The space radiation mutations are a real problem for any space exploration. They would need to line spaceships with lead, which is far too heavy, to prevent mutations. Also, over time, that would lead to mutations in babies born in space or on other planets. This said, maybe that is the future of humanity: mutated humans that may be able to better adapt to other planets.
I don't think I've ever read any science fiction that takes this into account.

Our Galaxy Appears to Be Touching Another Galaxy, Scientists Say: The "Milky Way and Andromeda are already overlapping and interacting."
Researchers are suggesting that the outer boundary of our home Milky Way galaxy may stretch much farther into the vastness of space than initially thought — and is in fact already touching its closest neighbor, the galaxy Andromeda.
As detailed in a paper published in the journal Nature Astronomy, the international team of scientists posits a new definition for the boundary between interstellar space and the "circumgalactic medium," (CGM) the cloud of gas that surrounds galaxies. LINK
Government Scientist Investigating Whether Aging Parts of Your Brain Can Be Replaced With Cloned Tissue: "We're... a couple steps away from reversing brain aging."
A biologist with the US government's research and development arm is working on a radical new approach to anti-aging treatments: replacing parts of the human brain with cloned tissues. As the MIT Technology Review reports, researcher Jean Hébert was recently hired by the US Advanced Projects Agency for Health (ARPA-H) for his revolutionary plan to bring for "functional brain tissue replacement." ...
While there are already transplants for things like hips and kidneys, the concept of replacing one brain for another is terrifying on an existential level because on a fundamental level, our brains make us who we are. Hébert's research, however, is more focused on "progressively" replacing parts of the brain using young, lab-grown tissues. If done slowly enough, the Tech Review explains, the idea is that the brain could adapt by moving around memories and other key identity facets to accommodate its new biological material. LINK

Scientists Found Genetic Mutations in Every Astronaut Blood Sample They Studied
When they examined decades-old blood samples from 14 NASA astronauts who flew Space Shuttle missions between 1998 and 2001, researchers found that samples from all 14 astronauts showed mutations in their DNA.
While these mutations are likely low enough not to represent a serious threat to the astronauts' long term health, the research underlines the importance of regular health screenings for astronauts, especially as they embark on longer missions to the Moon and beyond in coming years.
The specific mutations, as identified in a new study published in the journal Nature Communications Biology, were marked by a high proportion of blood cells that came from a single clone, a phenomenon called clonal hematopoiesis.
Mutations like this can be caused by exposure to excess ultraviolet radiation, and other forms of radiation including chemotherapy.
In this case, researchers are suspicious that the mutations may have been the result of space radiation. LINK
Matching sets of dinosaur footprints found on opposite sides of the Atlantic Ocean

Scientists Discover “Spatial Grammar” in DNA: Breakthrough Could Rewrite Genetics Textbooks
A breakthrough in genetic research has uncovered a “spatial grammar” in DNA, showing that the positioning of transcription factors critically influences gene activity, potentially reshaping how we understand gene regulation and disease. ... Transcription factors, the proteins that control which genes in one’s genome are turned on or off, play a crucial role in this code. Long thought of as either activators or repressors of gene activity, this research shows the function of transcription factors is far more complex.
“Contrary to what you will find in textbooks, transcription factors that act as true activators or repressors are surprisingly rare,” said WSU assistant professor Sascha Duttke, who led much of the research at WSU’s School of Molecular Biosciences in the College of Veterinary Medicine.
Rather, the scientists found that most activators can also function as repressors.
“If you remove an activator, your hypothesis is you lose activation,” said Bayley McDonald, a WSU graduate student who was part of the research team. “But that was true in only 50% to 60% of the cases, so we knew something was off.”
Looking closer, researchers found the function of many transcription factors was highly position-dependent.
They discovered that the spacing between transcription factors and their position relative to where a gene’s transcription began determined the level of gene activity. For example, transcription factors might activate gene expression when positioned upstream or ahead of where a gene’s transcription begins but inhibit its activity when located downstream, or after a gene’s transcription start site. “It is the spacing, or ‘ambience,’ that determines if a given transcription factor acts as an activator or repressor,” Duttke said. “It just goes to show that similar to learning a new language, to learn how gene expression patterns are encoded in our genome, we need to understand both its words and the grammar.” LINK

Earth’s Temperature Could Increase by 25 Degrees: Startling New Research Reveals That CO2 Has More Impact Than Previously Thought
Analysis of Pacific Ocean sediments shows doubling atmospheric CO2 might raise Earth’s temperature by up to 14 degrees, exceeding IPCC predictions, with historical data indicating significant future climate impacts.
Doubling the atmospheric CO2 levels could raise Earth’s average temperature by 7 to 14 degrees Celsius (13 to 25.2 degrees Fahrenheit), according to sediment analysis from the Pacific Ocean near California conducted by researchers from NIOZ and the Universities of Utrecht and Bristol.
The results were recently published in the journal Nature Communications.
“The temperature rise we found is much larger than the 2.3 to 4.5 degrees Celsius (4.1 to 8.1 degrees Fahrenheit) that the UN climate panel, IPCC, has been estimating so far,” said the first author, Caitlyn Witkowski. LINK
Elon Musk Claims He Just Activated the World's Most Powerful AI Supercomputer
Behold Colossus: Elon Musk's new supercomputer, allegedly powered by a staggering 100,000 Nvidia AI chips, which would be more than any single AI system on the planet.
Built in Tennessee for his artificial intelligence startup xAI, Musk announced Monday that the formidable data center was finally brought online over the Labor Day weekend, after spending just 122 days assembling it — a record, according to Nvidia.
"Colossus is the most powerful AI training system in the world," Musk said in a tweet. ... Musk claimed that, in a few months, Colossus will "double" in size to 200,000 AI chips, which will include 50,000 H200 GPUs, a newer version that Nvidia says will have nearly twice the memory capacity as its predecessor, and 40 percent more bandwidth.
... The monstrous supercomputer's launch, however, was preceded by controversy. Last week, Memphis locals who live near the Tennessee data center complained about "untenable levels of smog" created by the supercomputer, which could augur further disputes down the line at the xAI facility.
And that'll just be the beginning of Colossus' troubles. Its title as the most powerful AI training system will surely come under threat, too. It's not likely that other AI leaders, like OpenAI, Microsoft, Google, and Meta, will rest on their laurels, some of whom already possess hundreds of thousands of GPUs of their own.
Microsoft, for example, reportedly aims to amass 1.8 million AI chips by the end of the year (though this number sounds highly optimistic, if not infeasible). LINK

Robot controlled by a king oyster mushroom blends living organisms and machines
A wheeled bot rolls across the floor. A soft-bodied robotic star bends its five legs, moving with an awkward shuffle.
Powered by conventional electricity via plug or battery, these simple robotic creations would be unremarkable, but what sets these two robots apart is that they are controlled by a living entity: a king oyster mushroom.
By growing the mushroom’s mycelium, or rootlike threads, into the robot’s hardware, a team led by Cornell University researchers has engineered two types of robots that sense and respond to the environment by harnessing electrical signals made by the fungus and its sensitivity to light.
The robots are the latest accomplishment of scientists in a field known as biohybrid robotics who seek to combine biological, living materials such as plant and animal cells or insects with synthetic components to make partly living and partly engineered entities.
Biohybrid robots have yet to venture beyond the lab, but researchers hope one day robot jellyfish may explore oceans, sperm-powered bots may be able to deliver fertility treatments and cyborg cockroaches could search for survivors in the wake of an earthquake.

Professor of Medicine Says Death Appears to Be Reversible
In an interview with The Telegraph, associate professor of medicine at New York University's Langone Medical Center Sam Parnia insisted that by and large, the medical industry is still very behind on the concepts of death and dying.
According to Parnia, studies from the last five years — including some undertaken by his own eponymous lab at NYU — have suggested that our brains remain "salvageable for not only hours, but possibly days" after death.
In one such Parnia Lab study from last year, for instance, researchers found that some cardiac arrest patients had memories of their death experiences up to an hour after their hearts had stopped, and brain activity from those same patients suggests a similar phenomenon. For 40 percent of those subjects, brain activity also returned to normal or near-normal an hour into cardiopulmonary resuscitation (CPR).
Combined with other studies, including a particularly gruesome one out of Yale that involved decapitated pig brains being revived up to 14 hours after their beheadings, the seemingly death-defying doctor said that the idea that death is a definitive state is "simply a social convention that does not conform with scientific realities." ... By his reasoning, that process can be reversed not only by using extracorporeal membrane oxygenation (ECMO) machines, which acts as a body's heart and lungs when those functions have failed, but also specific cocktails of drugs that have been demonstrated to aid in the process of resurrection in animal studies. ...

Underground reservoir on Mars could fill oceans on the planet’s surface, study finds
A team of scientists estimates that there may be enough water, trapped in tiny cracks and pores of rock in the middle of the Martian crust, to fill oceans on the planet’s surface. The groundwater would likely cover the entirety of Mars to a depth of 1 mile (1.6 kilometers), the study found. The data came from NASA’s InSight lander, which used a seismometer to study the interior of Mars from 2018 to 2022.
Future astronauts exploring Mars would encounter a whole host of challenges if they tried to access the water, because it’s located between 7 and 12 miles (11.5 and 20 kilometers) beneath the surface, according to the study published Monday in the journal Proceedings of the National Academy of Sciences. But the finding uncovers new details about the geological history of Mars — and suggests a new place to search for life on the red planet if the water could ever be accessed. LINK

Scientists Capture Thought in Stunning New Detail
Recordings from thousands of neurons reveal how a person’s brain abstractly represents acts of reasoning.
Researchers have identified how the brain forms cognitive maps during inferential reasoning by analyzing neurons in epilepsy patients. The hippocampus, traditionally linked to physical space mapping, also structures cognitive processes. This study highlights how experiential and verbal learning impact neural representations, offering insights for potential neurological treatments. Using mathematical tools that Dr. Fusi honed to integrate recordings from thousands of neurons, the researchers recast the volunteers’ brain activity into geometric representations – into shapes, this is – albeit ones occupying thousands of dimensions instead of the familiar three dimensions that we routinely visualize.
“These are high-dimensional geometrical shapes that we cannot imagine or visualize on a computer monitor,” said Dr. Fusi. “But we can use mathematical techniques to visualize much-simplified renditions of them in 3D.” When the researchers compared shapes of brain activity between instances when the subjects made successful inferences with those when their inferences were unsuccessful, stark differences emerged.

Groundbreaking Study Identifies Universal Blueprint for Mammalian Brains
Researchers have developed a new method to describe the cerebral cortex, revealing a universal fractal pattern across mammalian species that could enhance our understanding of brain development and disease. ... The cerebral cortex is the outermost layer of the brain, and is responsible for complex functions such as thought, perception, and decision-making. Cerebral cortex folding, known as gyrification, is the process by which the brain’s surface develops grooves (sulci) and ridges (gyri). This folding increases the surface area of the brain, allowing for a greater number of neurons and more complex information processing. The cortex displays a wide diversity of shapes and sizes across and within species. ... This revealed that, despite the clear visual differences between the species’ cortices, all of them follow a universal scaling law, and resemble the same fractal shape. So, if you take the most complex cortex studied, that of a human, and use the team’s process of ‘melting’ to eliminate the smallest folds, it begins to resemble that of a chimpanzee. If you ‘melt’ the cortex of a chimpanzee, it resembles that of a rhesus monkey, and so on. ... LINK

Decoding Visual Deceptions: How the Brain Predicts and Rewrites Reality
A groundbreaking study reveals how the brain’s complex visual system not only perceives but also predicts and alters our view of the world. This in-depth look shows that our brain integrates past experiences with present visual information to construct reality, which can lead to deceptions or illusions. ... How do we learn to make sense of our environment? Over time, our brain builds a hierarchy of knowledge, with higher-order concepts linked to the lower-order features that comprise them. For instance, we learn that cabinets contain drawers and that Dalmatian dogs have black-and-white patches, and not vice versa. This interconnected framework shapes our expectations and perception of the world, allowing us to identify what we see based on context and experience.
“Take an elephant,” says Leopoldo Petreanu, senior author of the la Caixa-funded study. “Elephants are associated with lower-order attributes such as color, size, and weight, as well as higher-order contexts like jungles or safaris. Connecting concepts helps us understand the world and interpret ambiguous stimuli. If you’re on a safari, you may be more likely to spot an elephant behind the bushes than you would otherwise. Similarly, knowing it’s an elephant makes you more likely to perceive it as grey even in the dim light of dusk. But where in the fabric of the brain is this prior knowledge stored, and how is it learned?” LINK

This period witnessed an explosion of biodiversity according to fossil records, the causes of which have baffled scientists since Charles Darwin.

New Stanford Research Reveals Humans Age in Two Rapid Bursts: At 44 and 60
They found that thousands of molecules and microbes undergo shifts in their abundance, either increasing or decreasing — around 81% of all the molecules they studied showed non-linear fluctuations in number, meaning that they changed more at certain ages than other times. When they looked for clusters of molecules with the largest changes in amount, they found these transformations occurred the most in two time periods: when people were in their mid-40s, and when they were in their early 60s.
Although much research has focused on how different molecules increase or decrease as we age and how biological age may differ from chronological age, very few have looked at the rate of biological aging. That so many dramatic changes happen in the early 60s is perhaps not surprising, Snyder said, as many age-related disease risks and other age-related phenomena are known to increase at that point in life.
The large cluster of changes in the mid-40s was somewhat surprising to the scientists. At first, they assumed that menopause or perimenopause was driving large changes in the women in their study, skewing the whole group. But when they broke out the study group by sex, they found the shift was happening in men in their mid-40s, too. LINK

One hypothesis is that CWISE J1249 originally came from a binary system with a white dwarf, which exploded as a supernova when it pulled off too much material from its companion. Another possibility is that it came from a tightly bound cluster of stars called a globular cluster, and a chance meeting with a pair of black holes sent it soaring away. “When a star encounters a black hole binary, the complex dynamics of this three-body interaction can toss that star right out of the globular cluster,” says Kyle Kremer, incoming assistant professor in UC San Diego’s Department of Astronomy and Astrophysics.

Arbough's enthusiasm surrounding the implant — and the circumstances that led to its need in the first place — make its decline in functionality all the sadder.
... "It sucked. It was really, really hard," he told the podcaster. "I thought it would've been a cruel twist of fate if I had gotten to see the view from the top of this mountain and then have it all come crashing down after a month."
Despite all that, Arbaugh told the podcaster that he's still glad that he can still move a mouse cursor with his mind and have some level of independence left to him that he didn't have before.

This catalyst, developed through a combination of metal-organic frameworks and metal oxides, represents a significant advancement in the production of clean energy. It holds promise for reducing greenhouse gas emissions and providing a sustainable alternative to traditional hydrogen production methods, which rely on fossil fuels. LINK
Neuroscientists Have Pinpointed the Origins of Creativity in the Brain
A collaborative study by researchers from the University of Utah Health and Baylor College of Medicine has uncovered the crucial function of the default mode network in creativity using sophisticated brain imaging, highlighting possibilities for future therapeutic interventions. ... “There’s not a creativity cortex.” ... But there’s evidence that creativity is a distinct brain function. Localized brain injury caused by stroke can lead to changes in creative ability—both positive and negative. That discovery suggests that narrowing down the neurological basis of creativity is possible.
Shofty suspected that creative thought might rely strongly on parts of the brain that are also activated during meditation, daydreaming, and other internally focused types of thinking. This network of brain cells is the default mode network (DMN), so called because it’s associated with the “default” patterns of thought that happen in the absence of specific mental tasks. “Unlike most of the functions that we have in the brain, it’s not goal-directed,” Shofty says. “It’s a network that basically operates all the time and maintains our spontaneous stream of consciousness.”
The DMN is spread out across many dispersed brain regions, making it more difficult to track its activity in real-time. The researchers had to use an advanced method of brain activity imaging to understand what the network was doing moment-to-moment during creative thought. ... The researchers saw that during a creative thinking task in which participants were asked to list novel uses for an everyday item, like a chair or a cup, the DMN lit up with activity first. Then, its activity synchronized with other regions in the brain, including ones involved in complex problem-solving and decision-making. Shofty believes this means that creative ideas originate in the DMN before being evaluated by other regions.
What’s more, the researchers were able to show that parts of the network are required specifically for creative thought. When the researchers used the electrodes to temporarily dampen the activity of particular regions of the DMN, people brainstormed uses for the items they saw that were less creative. Their other brain functions, like mind wandering, remained perfectly normal. LINK
Scientists Use Nanoparticles to Remote Control Brains of Mice
Scientists at the Institute for Basic Science (IBS) in South Korea have developed a new way to control the minds of mice by manipulating nanoparticle-activated "switches" inside their brains with an external magnetic field.
The system, dubbed Nano-MIND (Magnetogenetic Interface for NeuroDynamics), works by controlling targeted regions of the brain by activating neural circuits.
While it's not the first "mind control" experiment involving animals, previous approaches have conventionally relied on invasive surgery and bulky external systems that limit the movement of test subjects, as Science Alert points out.
"This is the world's first technology to freely control specific brain regions using magnetic fields," said Jinwoo Cheon, director of the IBS Center for Nanomedicine, and senior author of a new paper published in the journal Nature Nanotechnology, in a statement about the research.

Cracking the Code of Life: New AI Model Learns DNA’s Hidden Language
GROVER, a new large language model trained on human DNA by researchers at Dresden University of Technology’s Biotechnology Center, can decode complex genomic information by treating DNA as a language. This innovative tool holds the potential to revolutionize genomics and accelerate personalized medicine. ... “GROVER learned the rules of DNA. In terms of language, we are talking about grammar, syntax, and semantics. For DNA this means learning the rules governing the sequences, the order of the nucleotides and sequences, and the meaning of the sequences. Like GPT models learning human languages, GROVER has basically learned how to ‘speak’ DNA,” explains Dr. Melissa Sanabria, the researcher behind the project. The team showed that GROVER can not only accurately predict the following DNA sequences but can also be used to extract contextual information that has biological meaning, e.g., identify gene promoters or protein binding sites on DNA. GROVER also learns processes that are generally considered to be “epigenetic”, i.e., regulatory processes that happen on top of the DNA rather than being encoded. LINK
MIT Claims New Artificial Neuron 1 Million Times Faster Than the Real Thing
Think and you’ll miss it: researchers at MIT claim to have successfully created analog synapses that are one million times faster than those in our human brains.
Just as digital processors need transistors, analog ones need programmable resistors. Once put into the right configuration, these resistors can be used to create a network of analog synapses and neurons, according to a press release.
These analog synapses aren’t just ultra-fast, they're remarkably efficient, too. And that's pretty important, because as digital neural networks grow more advanced and powerful, they require more and more energy, increasing their carbon footprint considerably.
As detailed in a new paper, the researchers hope their findings will advance the field of analog deep learning, a burgeoning field of artificial intelligence. LINK

When AI Is Trained With AI-Generated Data, It Starts Spouting Gibberish
A fascinating new study published in the journal Nature shows that AI models trained on AI-generated material will experience rapid "model collapse." Basically, as an AI model cannibalizes AI-generated data, its outputs become increasingly bizarre, garbled, and nonsensical, as if synthetic data — as opposed to high-quality, human-made material — breaks its brain.
On the one hand, the study's results serve as another reminder that AI models are incredibly responsive to their training data, and that allowing AI-generated material to seep into those datasets can have serious consequences for AI systems and the billion-dollar companies building them. At the same time, it underscores AI companies' ever-growing need for high-quality human material with which to train its models — an increasingly scarce, and thus increasingly valuable, resource that could stand to put generative AI advancement at a plateau.
"The message is we have to be very careful about what ends up in our training data," study co-author Zakhar Shumaylov, an AI researcher at the University of Cambridge, told Nature, warning that otherwise "things will always, provably, go wrong." LINK
MIT Economist Blasts AI Hype, Says It's Too Dumb to Really Impact Jobs: Companies are "over-investing in generative AI and then regretting it.
In an interview with NPR, MIT economist and leading AI skeptic Daron Acemoglu made a case that the tech is simply far too dumb to have a major impact.
When asked if generative AI would usher in revolutionary economic changes, Acemoglu had a straightforward answer.
"No. No. Definitely not," Acemoglu told NPR. "I mean, unless you count a lot of companies over-investing in generative AI and then regretting it, a revolutionary change."
... Generative AI is still struggling with many of the same challenges as when ChatGPT was first made available to the public in late 2022. For one, AI chatbots still have a strong tendency to "hallucinate," meaning that their connection to reality is tenuous at best. As NPR points out, experts have also argued that claims of generative AI intelligence are likely exaggerated, and aren't much more than "autocorrect on steroids": a statistical model that does little more than recognize patterns in data. ... Acemoglu argued that AI isn't capable of most tasks in a modern office. According to the economist, generative AI will only ultimately impact less than five percent of human tasks. He also predicted that the tech will only boost the gross domestic impact by roughly 1.5 percent over the next decade. While that's "nothing to be sneered at," he told NPR, "it's not revolutionary in any shape or form."

The Black Hole at the HEART of the universe ...
Black Holes: Not Destroyers but Protectors
A study has revealed that galaxies possess a regulatory mechanism similar to a heart and lungs, which controls their growth by limiting gas absorption. ...This mechanism, involving a supermassive black hole and its jet emissions, prevents galaxies from expanding too rapidly, ensuring their longevity and preventing premature aging into “zombie” galaxies.... In their analogy, the researchers compared the supermassive black hole at the center of a galaxy to its heart and the two bipolar supersonic jets of gas and radiation they emit to airways feeding a pair of lungs. Pulses from the black hole — or “heart” — can lead to jet shock fronts oscillating back and forth along both jet axes, much like the thoracic diaphragm in the human body moves up and down inside a chest cavity to inflate and deflate both lungs. This can result in jet energy being transmitted widely into the surrounding medium, just as we breathe out warm air, resulting in slowing galaxy gas accretion and growth. LINK

Unlocking the Secrets of LUCA, Earth’s Earliest Life Form
A University of Bristol-led study found that life on Earth, stemming from a common ancestor called LUCA (Last Universal Common Ancestor), flourished soon after the planet’s formation. Through genetic analysis and evolutionary modeling, researchers pinpointed LUCA’s existence to about 4.2 billion years ago, revealing it as a complex organism with an early immune system integral to Earth’s earliest ecosystems. LUCA is the hypothesized common ancestor from which all modern cellular life, from single-celled organisms like bacteria to the gigantic redwood trees (as well as us humans) descend. LUCA represents the root of the tree of life before it splits into the groups, recognized today, Bacteria, Archaea, and Eukarya. Modern life evolved from LUCA from various different sources: the same amino acids used to build proteins in all cellular organisms, the shared energy currency (ATP), the presence of cellular machinery like the ribosome and others associated with making proteins from the information stored in DNA, and even the fact that all cellular life uses DNA itself as a way of storing information. ... Co-author Professor Davide Pisani said: “Our study showed that LUCA was a complex organism, not too different from modern prokaryotes, but what is really interesting is that it’s clear it possessed an early immune system, showing that even by 4.2 billion years ago, our ancestor was engaging in an arms race with viruses.”

This is your brain on psilocybin
As he began the brain scan, neurologist Dr. Nico Dosenbach wasn’t sure if he’d been given a psychedelic or a placebo as part of a new clinical trial that would capture how the brain works on psilocybin, the main psychoactive ingredient in magic mushrooms. Suddenly he felt a faster heartbeat, a flush of energy and a change in vision. It wasn’t until his brain morphed into a computer, however, that he knew for sure he was on a psychedelic trip. ... Dosenbach is the co-senior author of a very small, pilot study that conducted up to 30 functional magnetic resonance imaging (fMRI) scans of healthy participants’ brains before, during and three weeks after a psychedelic trip on psilocybin. “We found that psilocybin desynchronizes the brain,” said co-senior author Ginger Nicol of the study published Wednesday in the journal Nature.
“When psilocybin is on board, the brain is disconnecting from its typical pathways and reconnecting to different parts of the brain,” said Nicol, an associate professor of psychiatry at Washington University School of Medicine in St. Louis.
... Each of the participants had different experiences, with only one not entering a state of mysticism, Dosenbach said.
“My sense of self stretched like I was the universe,” he said. “Other people reported they saw God, and if I was very religious, I could see that, but for me it was more like ‘Oh, I’m the universe.’
“And then it disappeared in what I think psychiatrists call ego death,” he said. “Simultaneously with that I lost my sense of place, and time stopped. It felt like I was literally there for days and then weeks figuring things out.”
One man was able to pinpoint the specific time during the fMRI scan that he had his most vivid mystical experience, Nicol said.
“He felt the light of God was shining on him,” she said. “We were able to actually go to that spot on the scan and pinpoint when he felt that — it happened at the peak of desynchronization(from the brain’s typical pathways).

AI Learns To Think Like Humans: A Game-Changer in Machine Learning
Researchers at Georgia Tech are advancing neural networks to mimic human decision-making by training them to exhibit variability and confidence in their choices, similar to how humans operate, as demonstrated in their study published in Nature Human Behaviour. Their model, RTNet, not only matches human performance in recognizing noisy digits but also applies human-like traits such as confidence and evidence accumulation, enhancing both accuracy and reliability. ... Humans make nearly 35,000 decisions each day, ranging from determining if it’s safe to cross the road to choosing what to have for lunch. Each decision involves evaluating options, recalling similar past situations, and feeling reasonably confident about the right choice. What might appear to be a snap decision actually results from gathering evidence from the environment. Additionally, the same person might make different decisions in identical scenarios at different times.
Neural networks do the opposite, making the same decisions each time. Now, Georgia Tech researchers in Associate Professor Dobromir Rahnev’s lab are training them to make decisions more like humans. This science of human decision-making is only just being applied to machine learning, but developing a neural network even closer to the actual human brain may make it more reliable, according to the researchers.

Carpenter ants amputate the legs of their nestmates to save their lives, study says
Humans aren’t the only ones capable of performing amputations to save lives.
Florida carpenter ants have been observed biting off the injured limbs of nestmates, depending on the location of the wounds, to help their counterparts survive, according to a new study.
About 90% to 95% of the ants receiving amputations make it through the process and continue with their duties within the nest just fine despite losing a leg, researchers found.

Surprising asteroid sample reveals Bennu may have originated from an ocean world
An early analysis of a sample collected from the asteroid Bennu suggests that the space rock had an unexpectedly water-rich past — and it may have even splintered off from an ancient ocean world. The NASA OSIRIS-REx mission scooped up the 4.3-ounce (121.6-gram) pristine sample from the near-Earth asteroid in 2020 and returned it to Earth last September. ... During a new analysis of the sample, the team discovered that Bennu’s dust is rich in carbon, nitrogen and organic compounds, all of which helped form the solar system. These ingredients are also essential to life as we understand it and could help scientists better understand how Earth-like planets evolve. ... “The presence and state of phosphates, along with other elements and compounds on Bennu, suggest a watery past for the asteroid,” said co-lead study author Dante Lauretta, principal investigator for OSIRIS-REx and regents professor at the University of Arizona, Tucson, in a statement. “Bennu potentially could have once been part of a wetter world. Although, this hypothesis requires further investigation.” LINK

THE UNIVERSE MAY BE SHAPED LIKE A HALL OF MIRRORS, SCIENTISTS SAY
For decades now, scientists have argued about how the universe is shaped, in the sense of complex parameters that govern the rules of space and time. Is it a simple open expanse, like a bigger version of the spaces we're used to? Does it wrap around on itself like a donut? Or something even stranger?
Now, new research published in the journal Physical Review Letters, in the inaugural paper from a new consortium of cosmologists known as the COMPACT Collaboration, found that the "topology" of the universe — the shape of its geometry, basically — is likely anything but simple.
... The researchers looked at the universe's cosmic microwave background, which is basically the inherent "glow" of space, dating back to ancient radiation at the dawn of time.
While they didn't nail down any one definite topology for the universe, they did find that data on the universe's background radiation doesn't rule out some seriously exotic shapes — and in fact, we might just live in something akin to an infinite hall of mirrors. ... Take the main focus of the paper, a shape known as a "3-torus." As the American Physical Society explained in a summary of the paper, that would be like if there was a cube on which each set of opposing sides were connected — meaning that no matter how large the universe appears, if you peer deep enough into its depths, you'll see the back of your head. ...

BEWARE THE THREE HORSEMEN OF THE OCEAN APOCALYPSE.
Extreme heat, acidification, and deoxygenation are all fearsome forces on their own. Combine two or more of them, and they can be catastrophic: they cause what's known as column-compound extreme events (CCX), which turn affected areas of the ocean virtually uninhabitable.
The research, which focused on the effects in the upper one thousand feet of the ocean, found that these compound events are growing, and now threaten up to 20 percent of global ocean volume. The waters of the North Pacific and the tropics are the most hard hit, as the only areas faced with full-blown triple CCX — at least so far.
To make matters worse, the events are only getting more extreme, lasting three times longer — up to 30 days — and are six times more intense compared to the 1960s, per the Guardian. And wherever they occur, they can cut down the amount of habitable space by up to 75 percent.
"The impacts of this have already been seen and felt," study lead author Joel Wong, a researcher at ETH Zurich, told the newspaper. "Intense extreme events like these are likely to happen again in the future and will disrupt marine ecosystems and fisheries around the world."

REMOTE AMAZON TRIBE FINALLY GETS INTERNET, GETS HOOKED ON PORN AND SOCIAL MEDIA
The New York Times reports on what may sound a bit familiar: young people poring over social media feeds, streaming soccer games, and of course, gossiping over WhatsApp. Evenings are spent lounging around on their phones and playing first-person shooters and other video games.
"When it arrived, everyone was happy," said Tsainama Marubo, 73. "But now, things have gotten worse."
Some of the young men are especially getting a kick out of it. Alfredo Marubo, a leader of an association of the tribe's villages, lamented that the boys, now with their own group chats, were sharing porn and other explicit videos — which is unprecedented in their culture that considers kissing in public taboo.... "Everyone is so connected that sometimes they don't even talk to their own family," he told the NYT.
Tsainama echoed those fears, but was more conflicted. "Young people have gotten lazy because of the internet," she said. "They're learning the ways of the white people. But please don't take our internet away." ... New job opportunities have opened up. Villages can now easily coordinate over group chats, and also reach out to local authorities.
"It's already saved lives," Enoque Marubo, who was one of the first in the tribe to push for an internet connection, told the NYT, such as in the case of venomous snakebites, which need immediate medical treatment.
"The leaders have been clear," he added. "We can't live without the internet."

Scientists used machine learning to discover what they say could be a new way to speed up the process of breaking down plastic significantly
As detailed in a new paper published in the journal Nature, a research team from the University of Texas at Austin modified an enzyme to break down the individual components of polyethylene terephthalate (PET), a commonly used plastic that makes up a staggering 12 percent of global waste.
Impressively, the modified enzyme also reduced the amount of time it takes for the plastic to degrade from months to a just single week.
The process, called depolymerization, has the added benefit of allowing the broken down monomers to be reconstituted back into virgin PET plastic, a potentially revolutionary way of recycling the astronomical amounts of plastic waste we've accumulated.
That all depends, though, on figuring out a reliable and affordable way to scale up and industrialize the process.

SCIENTISTS CONNECT 16 MINI BRAINS MADE OF HUMAN TISSUE TO CREATE A "LIVING COMPUTER"
Switzerland-based startup FinalSpark claims to have built a unique computer processor made from 16 mini brains made from human brain tissue, Tom's Hardware reports — and they are positioning this "living computer" as an alternative to silicon-based computing.
And now, other researchers can remotely access the startup's biocomputer, the Neuroplatform, to conduct studies on, say, artificial intelligence, which typically requires enormous resources.
"One of the biggest advantages of biological computing is that neurons compute information with much less energy than digital computers," FinalSpark scientist and strategic advisor Ewelina Kurtys wrote in a company blog post earlier this month. "It is estimated that living neurons can use over 1 million times less energy than the current digital processors we use."
The startup takes brain organoids, small samples of human brain tissue derived from neural stem cells, and places them in a special environment that keeps these organoids alive. They then hook up these mini brains to specialized electrodes to perform computer processing and digital analog conversions to transform neural activity into digital information.
The concept of living computers has been around for quite some time now. Last year, for instance, scientists hooked up neurons to electrical circuits, resulting in a device that could perform voice recognition.
These unusual machines have some noteworthy advantages over their silicon-based counterparts, including a significantly smaller carbon footprint.

Dark Holes ...
Scientists may have found an answer to the mystery of dark matter.
... The study, published June 6 in the journal Physical Review Letters, reveals that these black holes must have appeared in the first quintillionth of a second of the big bang: “That is really early, and a lot earlier than the moment when protons and neutrons, the particles everything is made of, were formed,” Alonso-Monsalve said.
...
“You cannot find quarks and gluons alone and free in the universe now, because it is too cold,” Alonso-Monsalve added. “But early in the big bang, when it was very hot, they could be found alone and free. So the primordial black holes formed by absorbing free quarks and gluons.”
Such a formation would make them fundamentally different from the astrophysical black holes that scientists normally observe in the universe, which are the result of collapsing stars. Also, a primordial black hole would be much smaller — only the mass of an asteroid, on average, condensed into the volume of a single atom. But if a sufficient number of these primordial black holes did not evaporate in the early big bang and survived to this day, they could account for all or most dark matter. ... LINK

An AI chatbot named VIC, or Virtually Integrated Citizen, is trying to make it onto the ballot in this year's mayoral election for Wyoming's capital city of Cheyenne. But as reported by Wired, Wyoming's secretary of state is battling against VIC's legitimacy as a candidate — and now, an investigation is underway. ... According to Wired, VIC, which was built on OpenAI's GPT-4 and trained on thousands of documents gleaned from Cheyenne council meetings, was created by Cheyenne resident and library worker Victor Miller. Should VIC win, Miller told Wired that he'll serve as the bot's "meat puppet," operating the AI but allowing it to make decisions for the capital city.
And why should VIC run? According to its creator: paperwork!
"My campaign promise," Miller told Wired, "is he's going to do 100 percent of the voting on these big, thick documents that I'm not going to read and that I don't think people in there right now are reading." (Also, VIC is a "he," apparently.)

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.
“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept. ... Now, a new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that’s attracting scrutiny and alternate theories. ... “It’s difficult for us to find an explanation for these sources, because we don’t have enough data to prove what is the real cause of the infrared glow,” he said. “They could be Dyson spheres, because they behave like our models predict, but they could be something else as well.”
Among the natural causes that could explain the infrared glow are an unlucky alignment in the observation, with a galaxy in the background overlapping with the star, planetary collisions creating debris, or the fact that the stars may be young and therefore still surrounded by disks of hot debris from which planets would later form.

‘Once-in-a-lifetime’ explosion will bring a new star to the night sky
Astronomers are expecting a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA.
“It’s a once-in-a-lifetime event that will create a lot of new astronomers out there, giving young people a cosmic event they can observe for themselves, ask their own questions, and collect their own data,” said Dr. Rebekah Hounsell, an assistant research scientist specializing in nova events at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement. “It’ll fuel the next generation of scientists.”
The expected brightening event, known as a nova, will occur in the Milky Way’s Corona Borealis, or Northern Crown constellation, which is located between the Boötes and Hercules constellations.
While a supernova is the explosive death of a massive star, a nova refers to the sudden, brief explosion from a collapsed star known as a white dwarf. The dwarf star remains intact, releasing material in a repetitive cycle that can occur for thousands of years.

CHINESE LANDER INSTRUMENT DETECTS NEGATIVE IONS ON FAR SIDE OF MOON
Within just over 48 hours, China's Chang'e-6 lunar touched down on the far side of the Moon, successfully scooped up samples, and kicked off once again.
... These ions are created when charged particles from the Sun pelt the lunar surface, causing particles there to react and become negatively charged. Here on Earth, the planet's magnetic field stops these particles from ever reaching the surface.
But since the Moon doesn't have a magnetic field, its surface is extremely vulnerable to these charged particles. Unlike positively charged particles, however, they never make it back into orbit, forcing scientists to study them on the surface instead.
Before making its observations, the NILS instrument went through cycles of reboots and blackouts as it adjusted to the extreme conditions on the lunar surface.
Fortunately it prevailed, sending back usable data. The observations could have considerable implications for our understanding of what goes on in other spots in our celestial neighborhood that aren't protected by a magnetic field either.

PLAN TO TRANSPLANT A HUMAN HEAD FROM ONE BODY TO ANOTHER
Hashem Al-Ghaili, a biologist and filmmaker, presents in the video a gory yet goofy illustration of how the bizarre experiment could be carried out: two identical autonomous robots, each with multiple arms, would simultaneously operate on the healthy brain-dead donor body and the presumably worn-out body that's the source of the head and brain.
Labeling the whole concept under the catchy brand name of "BrainBridge," Al-Ghaili conceives that this process would unfold like an assembly line, with one robot surgically removing the recipient's entire head while the other robot does the same to the donor's. Then a mobile platform would shift the recipient's head to the healthy donor body and suture these two disparate pieces together.

AFRICAN WORKERS DOING OPENAI'S TRAINING SAY THEY'RE BEING SUBJECTED TO "MODERN DAY SLAVERY"
Low-paid AI workers in Africa who perform AI and social media content moderation work for major Silicon Valley companies like Meta and OpenAI have published an open letter imploring US President Joe Biden to help ensure fair working conditions in a system that the letter's 97 signees say amounts to "modern day slavery," Wired reports. ...
To build AI models, like OpenAI's DALL-E image creator or Meta's "Llama" language model, those companies require a massive — and endless — amount of data, which has generally been acquired by a process of scraping the web. But AI models are what they eat: if you feed them a ton of wretched, unsafe, or low-quality material, their outputs will reflect those undesirable qualities.
That's where these workers come in. Their job is effectively to clean AI training datasets, removing bad or unsafe content and providing labels for text, images, and other inputs. But this job takes a toll; these folks are tasked with constantly consuming the worst aspects of humanity, all to ensure the safety of what those on the other side of the process experience as a human-free tool.
This work is done at an incredibly low wages. Largely based in Kenya, African content moderators are often paid a measly sum of less than two dollars an hour. In the letter, the moderators also say their work has left them with life-altering post-traumatic stress disorder (PTSD); the signees further claim that they "weren't warned about the horrors of the work" before starting. ... "US tech giants export their toughest and most dangerous jobs overseas," the document continues. "Our work involves watching murder and beheadings, child abuse and rape, pornography and bestiality, often for more than 8 hours a day." ...
African workers who label AI data or screen social posts for US tech giants are calling on President Biden to raise their plight with Kenya's president, William Ruto, who visits the US this week.
How AI and bionics are helping Ukrainian soldiers return to action
Since the start of the war, an estimated 20,000 Ukrainians have lost limbs. Such injuries typically end military careers, but advancements in bionics are enabling some veterans to resume what they see as their duty.
“For me, prosthetics were made in such a way that I’m returning back to the army,” Kucherenko told CNN.
Kucherenko was fitted with two bionic hands that are new to the market. The Esper Hand is the first product from Esper Bionics, a Ukrainian-US based company focused on next-generation prosthetics. ...
Artificial Intelligence is disrupting many industries, but it is also offering up unprecedented solutions. In the field of bionic prosthetics, AI or machine learning can help patients who’ve lost limbs regain functions – and perhaps even gain functions they didn’t originally have with human limbs.
‘I’m the new Oppenheimer!’: my soul-destroying day at Palantir’s first-ever AI warfare conference
America’s military-industrial complex took center stage at AI Expo for National Competitiveness, where a fire-breathing panel set the tone
... . The vibe for the expo, according to the Guardian, was quickly set by a panel of speakers that included billionaire former Google CEO and current drone manufacturing hopeful Eric Schmidt, billionaire Palantir cofounder Alex Karp, CIA deputy director David Cohen, and Former Chairman of the Joint Chiefs of Staff Mark Milley.
Much of the panel's conversation reportedly centered on the ongoing conflict in Israel and Palestine. And Karp — whose company inked its most recent contract with the US Army in March, this one worth a cool $178 million — used the platform to spew his strikingly candid views on the conflict, US war efforts, and, uh, paganism.
Speaking about campus protests, for instance, Karp blamed student backlash against Israel's response in Gaza on "pagan religion infecting our universities" and referred to demonstrations as an "infection inside of our society," according to the Guardian. He chillingly added that a US failure to quell public dissent against a conflict could be chalked up to an ideological failure, declaring that "if we lose the intellectual debate, you will not be able to deploy any armies in the west ever."
"The peace activists are war activists," Karp — who, again, is a military contractor — continued, according to the Guardian. "We are the peace activists."

Harvard Physicists Demonstrate First Metro-Area Quantum Network in Boston
Imagining a quantum internet capable of transmitting hacker-proof information globally through photons superimposed in different quantum states is one thing; demonstrating its feasibility in the real world is quite another.
That’s exactly what Harvard physicists have done. They used existing Boston-area telecommunication fiber in a demonstration of the world’s longest fiber distance between two quantum memory nodes to date. Think of it as a simple, closed internet between points A and B, carrying a signal encoded not by classical bits like the existing internet, but by perfectly secure, individual particles of light. ... The Harvard team established the practical makings of the first quantum internet by entangling two quantum memory nodes separated by an optical fiber link deployed over a roughly 22-mile loop through Cambridge, Somerville, Watertown, and Boston. The two nodes were located a floor apart in Harvard’s Laboratory for Integrated Science and Engineering. ... “Showing that quantum network nodes can be entangled in the real-world environment of a very busy urban area, is an important step towards practical networking between quantum computers,” Lukin said. ,,,

How a Newly Mapped Brain Circuit Could Transform Panic Disorder Treatment
Salk researchers have identified a specific brain circuit outside the amygdala that could lead to new treatments for panic disorder. This circuit involves neurons that communicate via a neuropeptide called PACAP, which, when activated during a panic attack, triggers receptor neurons and produces panic symptoms. This discovery points to PACAP and its receptor as potential targets for future therapeutics, fundamentally different from current treatments that focus on the serotonin system.
Dartmouth Researchers Have Mapped How the Brain Regulates Emotions
A new study by Dartmouth researchers identifies specific brain regions involved in emotion regulation and explores the neurochemical interactions that influence our emotional responses. The findings, which have potential clinical implications, highlight the importance of combining psychological and pharmaceutical approaches in mental health treatments. ... The new study reveals that emotion regulation, also known in neuroscience as “reappraisal,” involves particular areas of the anterior prefrontal cortex and other higher-level cortical hierarchies whose role in emotion regulation had not previously been isolated with this level of precision. These regions are involved in other high-level cognitive functions and are important for abstract thought and long-term representations of the future.

FIRST NEURALINK PATIENT WANTS TESLA ROBOT HE CAN CONTROL WITH HIS MIND: "IT WOULD ELIMINATE PROBABLY 90 PERCENT OF THE THINGS THAT I NEED OTHER PEOPLE FOR."
Now that the first Neuralink patient, Noland Arbaugh, is a whiz at playing video games and noodling around his laptop with the power of his new brain implant, he's told Wired he'd like to go one step further and get a Tesla Optimus robot and control it with his mind.
"I think it would be so freakin’ cool if I had a [Tesla] Optimus robot that I could control with it that would do basically everything for me and be a caretaker," Arbaugh, a quadriplegic, told Wired. "It would eliminate probably 90 percent of the things that I need other people for."
Arbaugh would also like a Tesla vehicle that he could connect to via the Neuralink device in his brain and get around town.
"If I could do all that on my own, man, it would change everything," he said.
... The major hiccup that has happened since he got his implant was that some wires inside his brain came loose and his implant stopped working as effectively until Neuralink tweaked the software.
"It seems like the threads have stabilized, and even some that were pulled out of my brain had found their way back in," he said. "I’m not worried about it now."

Unlocking Memory: Neuroscientists Reveal How the Brain Decides What To Remember
Neuroscientists have determined that some daily experiences are transformed into permanent memories during sleep through a process facilitated by the brain. A recent study led by NYU Grossman School of Medicine has identified “sharp wave-ripples” in the hippocampus as the key mechanism that selects which memories to retain permanently. These ripples occur during idle moments and play a crucial role in determining which experiences, followed closely by multiple ripples, are consolidated into long-lasting memories during sleep.
Rewiring the Brain: How Practice Really Makes Perfect
Practice makes perfect” is no mere cliché, according to a new study from researchers at Rockefeller University and UCLA. Instead, it’s the recipe for mastering a task, because repeating an activity over and over solidifies neural pathways in your brain.
As they describe in Nature, the scientists used a cutting-edge technology developed by Rockefeller’s Alipasha Vaziri to simultaneously observe 73,000 cortical neurons in mice as the animals learned and repeated a given task over two weeks. The study revealed that memory representations transform from unstable to solid in working memory circuits, giving insights into why performance becomes more accurate and automatic following repetitive practice.

Ocean water is rushing miles underneath the ‘Doomsday Glacier’ with potentially dire impacts on sea level rise
Ocean water is pushing miles beneath Antarctica’s “Doomsday Glacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space to perform an X-ray of the crucial glacier.
As the salty, relatively warm ocean water meets the ice, it’s causing “vigorous melting” underneath the glacier and couldmean global sea level rise projections are beingunderestimated, according to the study published Monday in the Proceedings of the National Academy of Sciences.
The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida. It’s also Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice.
Thwaites, which already contributes 4% to global sea level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world’s coastal communities.

Scientists say they’ve found where the sun’s magnetic field originates
The sun has a powerful magnetic field that creates sunspots on the star’s surface and unleashes solar storms such as the one that bathed much of the planet in beautiful auroras this month.
But exactly how that magnetic field is generated inside the sun is a puzzle that has vexed astronomers for centuries, going back to the time of Italian astronomer Galileo,who made the first observations of sunspots in the early 1600s, and noticed how they varied over time.
Researchers behind an interdisciplinary study have put forth a new theory in a report published Wednesday in the journal Nature. In contrast to previous research that assumed the sun’s magnetic field originates from deep within the celestial body, they suspect the the source is much closer to the surface.

MIT Researchers Discover the Universe’s Oldest Stars
MIT astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way’s “halo” — the cloud of stars that envelopes the main galactic disk — and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape. ... The researchers have coined the stars “SASS,” for Small Accreted Stellar System stars, as they believe each star once belonged to its own small, primitive galaxy that was later absorbed by the larger but still growing Milky Way. Today, the three stars are all that are left of their respective galaxies. They circle the outskirts of the Milky Way, where the team suspects there may be more such ancient stellar survivors.

The researchers looked at the universe's cosmic microwave background, which is basically the inherent "glow" of space, dating back to ancient radiation at the dawn of time.
While they didn't nail down any one definite topology for the universe, they did find that data on the universe's background radiation doesn't rule out some seriously exotic shapes — and in fact, we might just live in something akin to an infinite hall of mirrors. ... that would be like if there was a cube on which each set of opposing sides were connected — meaning that no matter how large the universe appears, if you peer deep enough into its depths, you'll see the back of your head.

NASA Simulation’s Plunge Into a Black Hole
This new, immersive visualization produced on a NASA supercomputer represents a scenario where a camera — a stand-in for a daring astronaut — enters the event horizon, sealing its fate. Goddard scientists created the visualizations on the Discover supercomputer at the NASA Center for Climate Simulation. The destination is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located at the center of our Milky Way galaxy. To simplify the complex calculations, the black hole is not rotating. A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds the black hole and serves as a visual reference during the fall. So do glowing structures called photon rings, which form closer to the black hole from light that has orbited it one or more times. A backdrop of the starry sky as seen from Earth completes the scene.
The problem with space junk – and how to solve it
Proponents of a circular space economy advocate for a transformative departure from this wasteful paradigm. Much like embracing reusable materials on Earth, transitioning to a circular space economy means designing space systems with reuse, refurbishment and recyclability in mind. Satellites should be built to have extended lifespans, allowing for upgrades and modifications rather than being discarded after a single mission. ... Rather than leaving defunct satellites to drift aimlessly in orbit or plunge unpredictably to Earth we must adopt controlled reentry procedures. This means purposefully making the satellite burn up in the atmosphere, while at the same time ensuring that the particles produced by this process don’t pollute it. That requires us to utilize research and engineering to determine the best materials and designs for satellites. This would ensure that objects safely burn up, minimizing the risk of debris scattering across our lands and oceans and not polluting the atmosphere in the process. ...

One new feature, called Ask Photos, allows users to search photos for deeper insights, such as asking when your daughter learned to swim or recall what your license plate number is, by looking through saved pictures.
He also showed how users can ask Gemini 1.5 Pro to summarize all recent emails from your child’s school by analyzing attachments, and summarizing key points and spitting out action items.
Meanwhile, Google executives took turns demonstrating other capabilities, such as how the latest model could “read” a textbook and turn it into a kind of AI lecture featuring natural-sounding teachers that answer questions.

A Google executive also demoed a virtual “teammate” that can help stay on top of to-do lists, organize data and manage workflow.
The company also highlighted search improvements by allowing users to ask more natural or more focused questions, and providing various versions of the responses, such as in-depth or summarized results. It can also make targeted suggestions, such as recommending kid friendly restaurants in certain locations, or note what might be wrong with a gadget, such as a camera, by taking a video of the issue via Google Lens.

Researchers Warn: AI Systems Have Already Learned How To Deceive Humans
Numerous artificial intelligence (AI) systems, even those designed to be helpful and truthful, have already learned how to deceive humans. In a review article recently published in the journal Patterns, researchers highlight the dangers of AI deception and urge governments to quickly establish robust regulations to mitigate these risks.
“AI developers do not have a confident understanding of what causes undesirable AI behaviors like deception,” says first author Peter S. Park, an AI existential safety postdoctoral fellow at MIT. “But generally speaking, we think AI deception arises because a deception-based strategy turned out to be the best way to perform well at the given AI’s training task. Deception helps them achieve their goals.” ...

Cambridge Experts Warn: AI “Deadbots” Could Digitally “Haunt” Loved Ones From Beyond the Grave
According to researchers at the University of Cambridge, artificial intelligence that allows users to hold text and voice conversations with lost loved ones runs the risk of causing psychological harm and even digitally “haunting” those left behind without design safety standards.
‘Deadbots’ or ‘Griefbots’ are AI chatbots that simulate the language patterns and personality traits of the dead using the digital footprints they leave behind. Some companies are already offering these services, providing an entirely new type of “postmortem presence.”
AI ethicists from Cambridge’s Leverhulme Centre for the Future of Intelligence outline three design scenarios for platforms that could emerge as part of the developing “digital afterlife industry,” to show the potential consequences of careless design in an area of AI they describe as “high risk.” ....

Scientists say they’ve discovered a ‘phonetic alphabet’ in whale calls
Scientists have accomplished a whale of a feat. They’ve identified previously unknown complexity in whale communication by analyzing thousands of recorded sequences of sperm whale clicks with artificial intelligence.
Variations in tempo, rhythm and length of the whales’ click sequences, called codas, weave a rich acoustic tapestry. These variables hint that whales can combine click patterns in multiple ways, mixing and matching phrases to convey a broad range of information to one another.
What sperm whales are saying with their clicks remains a mystery to human ears. Still, uncovering the scope of whales’ vocal exchanges is an important step toward linking whale calls to specific messages or social behaviors, the scientists reported May 7 in the journal Nature Communications.
Scientists using AI have found sperm whales can vary the tempo, rhythm and length of their click sequences, creating a richer communication system than realized.
