I want a Zafu that is harder than steel and bulletproof (in case the Zendo is attacked!) ...

MIT researchers have developed a new material that's as strong as steel but as light as plastic.

It can be easily manufactured in large quantities, and the use cases range from lightweight coatings for cars and phones to building blocks for massive structures such as bridges, according to Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of a new study.

“We don’t usually think of plastics as being something that you could use to support a building, but with this material, you can enable new things,” he said in a statement from MIT. “It has very unusual properties and we’re very excited about that.”

The material is several times stronger than bulletproof glass, and the amount of force needed to break it is twice that of steel, despite the fact that the material has only about one-sixth the density of steel, according to MIT.

The researchers were able to do this by developing a new process to form polymers. Plastics are an example of polymers, along with rubber and glass. ...

Well, a little mystery partially resolved in the Cohen house, but new mysteries added.

I found this old pot in a local junk shop about 3 years ago, and suspected that it is a kind of old rice cooking pot from maybe the Kofun (Burial Tumulus) Age in Japan, about 1500 to 1800 years ago. Because of Covid, I never got to show it to an expert, but finally did yesterday, asking our local city archeologist his opinion (yes, cities in Japan, like many in Europe, have town archeologists, because they are always digging up old things).

Turns out that I was partly wrong. While it appears to be an old rice cooking pot, it seems to be from the much earlier Late/Final Jomon period, the end of the Japanese stone age, about 1500 B.C. to 300 B.C., so maybe 2,500 or 3,000 years old? It is partially restored by someone, but we don't know how it ended up in the junk shop.

Late Jōmon (ca. 1500–1000 B.C.)
As the climate began to cool, the population migrated out of the mountains and settled closer to the coast, especially along Honshū’s eastern shores. Greater reliance on seafood inspired innovations in fishing technology, such as the development of the toggle harpoon and deep-sea fishing techniques. This process brought communities into closer contact, as indicated by greater similarity among artifacts. Circular ceremonial sites comprised of assembled stones, in some cases numbering in the thousands, and larger numbers of figurines show a continued increase in the importance and enactment of rituals.

Final Jōmon (ca. 1000–300 B.C.)
As the climate cooled and food became less abundant, the population declined dramatically. Because people were assembled in smaller groups, regional differences became more pronounced. As part of the transition to the Yayoi culture, it is believed that domesticated rice, grown in dry beds or swamps, was introduced into Japan at this time.

Now, here is the mystery. First, it does not appear to be from this region, but may be from Hokkaido in far northern Japan. However, rice had just come to Japan at the time, and is not thought to have made it this far north. So, it must be from Kyushu in southern Japan, in the very early days of rice cultivation in Japan! However, he is not sure, and it will need further research. He is only sure that it is late Jomon period.

Here are two pictures. It was a functional device, a family's kitchen vessel not made for beauty. However, you can see the lines carved into the surface, using a pressed rope pattern to make the design. The blackness either comes from the firing of the pottery or long use in cooking.

The hole shows that it was probably a steamer for rice, used in some kind of oven like this ...

So, new mysteries to investigate!

The pot is not of financial worth in any way, but does have historical and personal value!

3 paralyzed men can walk again after getting electrode implant

The device stimulates specific spinal nerves.

Three men with paralyzing spinal cord injuries can now stand, walk and cycle after electrodes were implanted into their spinal cords.

The electrodes deliver electrical pulses to specific regions of the spinal cord and thus activate muscles in the trunk and legs, according to a new study, published Monday (Feb. 7) in the journal Nature Medicine. The soft, flexible device lies directly on top of the spinal nerves, beneath the vertebrae, and can be controlled wirelessly with software, operated from a tablet, and a handheld clicker.

The software communicates with a pacemaker-like device in the abdomen, which then directs the activity of the nerve-bound electrodes on the spinal cord. So, with the tap of a touch screen, the user of the implant can prompt their device to generate a precise pattern of stimulation. These stimulation patterns translate to patterns of muscle activity, allowing the user to walk, cycle, or swim, for instance. Users can also manually switch between these stimulation patterns with their clicker. "All three patients were able to stand, walk, pedal, swim and control their torso movements in just one day, after their implants were activated ..."

After the initial implantation, the patients underwent extensive training to get used to using the device and regain muscle mass and motor control, co-senior author Dr. Jocelyne Bloch, an associate professor of neurosurgery at Lausanne University Hospital, told The Guardian. "It was not perfect at the beginning, but they could train very early to have a more fluid gait," she said. Eventually, the patients progressed from using the implants only in a controlled lab setting to using them out and about in their daily lives.

After four months of training, one patient, Michel Roccati, was able to walk about 0.6 mile (1 kilometer) outside the lab and without stopping, with only a frame for balance, AFP reported. He can now continuously stand for about two hours. Like the other participants in the trial, Roccati has a complete spinal cord injury, meaning the nerves below his site of injury cannot communicate with the brain at all. He was injured in a motorcycle accident in 2019 and lost both feeling and motor control in his legs.

...

The team is also investigating whether a similar stimulator could be implanted directly into the motor cortex, a key region of the brain for controlling voluntary movement, Courtine told NBC News. Such a device could allow people with paralysis to direct their movements without the aid of a tablet or clicker.

Big while small, yet small is big ...

Largest galaxy ever discovered baffles scientists

Astronomers just found the largest galaxy ever discovered, and they have no idea how it got so big.

At 16.3 million light-years wide, the Alcyoneus galaxy has a diameter 160 times wider than the Milky Way and four times that of the previous title holder, IC 1101, which spans 3.9 million light-years, researchers reported in a new study.

... The galactic monster is an especially large example of a radio galaxy, or a galaxy with a supermassive black hole at the center which gobbles up enormous amounts of matter before spitting it out — sending gigantic two jets of plasma moving at close to the speed of light.

... But other than its gigantic plumes, Alcyoneus is a normal elliptical galaxy, with a total mass roughly 240 billion times the mass of the sun (half that of the Milky Way's) and a central supermassive black hole 400 million times the sun's mass (100 times less massive than the largest black hole). In fact, Alcyoneus' center is on the small side compared with those of most radio galaxies.

... For now, the astronomers are stumped, but they are investigating some potential explanations. One possibility is that the galaxy's surrounding environment has a lower density than is usual, enabling its jets to expand across unprecedented scales. Another possible explanation is that Alcyoneus exists inside a filament of the cosmic web, a vast and little-understood structure of gas and dark matter that links galaxies.

Three galaxies are tearing each other apart in stunning new Hubble telescope image

This twisty-turny collision is a preview of what awaits our galaxy.

Corkscrewing through the cosmos, three distant galaxies collide in a stunning new image captured by NASA's Hubble Space Telescope.

This cosmic crash is known as a triple galaxy merger, when three galaxies slowly draw each other nearer and tear each other apart with their competing gravitational forces. Mergers like these are common throughout the universe, and all large galaxies — including our own, the Milky Way — owe their size to violent mergers like this one.

As chaotic as they seem, mergers like these are more about creation than destruction. As gas from the three neighboring galaxies collides and condenses, a vast sea of material from which new stars will emerge is assembled at the center of the newly unified galaxy.

Existing stars, meanwhile, will survive the crash mostly unscathed; while the gravitational tug-of-war among the three galaxies will warp the orbital paths of many existing stars, so much space exists between those stars that relatively few of them are likely to collide ...

The galaxy cluster seen above is called IC 2431, located about 681 million light-years from Earth ...

But some good news ...

Meanwhile, our galaxy appears on track to combine with the nearby Andromeda galaxy about 4.5 billion years from now. The merger will totally alter the night sky over Earth but will likely leave the solar system unharmed, according to NASA.

It's the largest solar prominence ever observed in a single image together with the full disc of the sun, ESA said in a statement released Friday.

The solar eruption took place on February 15 and extended millions of miles into space. The image was taken by the Full Sun Imager of the Extreme Ultraviolet Imager onboard the Solar Orbiter. ...

... these ejections are directed toward Earth, they can disrupt technology reliant on satellites. The ejections also cause the northern lights.
However, in this instance, the coronal mass ejection was traveling away from us.

Glowing clouds surround an exploded star in NASA mission's stunning first image

... A new pair of X-ray eyes on the universe is allowing us to see extreme objects like never before.

Just over two months after launching to space, NASA's newest explorer --- the Imaging X-Ray Polarimetry Explorer, or IXPE [JUNDO: not to be confused with Webb ] -- shared its very first images.

And they are stunning. The images offer a glimpse of Cassiopeia A, the famous remnant of a supernova, or exploding star.

Glowing purple gas clouds can be seen around the remains of the star. These clouds were created when shock waves from the explosion heated surrounding gas to incredibly high temperatures, accelerating high energy particles called cosmic rays.

... The beautiful remnants of the Cassiopeia A supernova are located about 11,000 light-years away from Earth. It is now a giant bubble of hot, expanding gas, and it's the youngest known remnant from a supernova explosion, dating back 340 years ago, in our Milky Way galaxy. The light from this supernova first reached Earth in the 1670s.

https://us.cnn.com/2022/02/16/world/...scn/index.html

This image shows supernova remnant Cassiopeia A, combining the first X-ray data collected by NASA's Imaging X-ray Polarimetry Explorer in purple, with high-energy X-ray data from NASA's Chandra X-Ray Observatory in blue.


This IXPE image maps the intensity of X-rays coming from Cassiopeia A. The colors, including cool purple, blue, red and white, correspond with the increasing brightness of the X-rays.

We are Each Other: Scientists create biggest-ever human family tree

It is true, we are a great family ...

Scientists create biggest-ever human family tree, dating back 100,000 years

Researchers have used genetics to create the largest human family tree ever made, allowing individuals to find out who their distant ancestors were and where they lived, as well as exactly how they are related to everyone alive today.

The research, carried out by scientists from the University of Oxford's Big Data Institute, combines human genomes from a variety of sources -- both ancient and modern DNA -- to better understand human history and evolution.

Just as a family tree shows how an individual is related to their parents or siblings, genetic genealogy reveals which genes are shared between two individuals, lead author Anthony Wilder Wohns, now a postdoctoral researcher at the Broad Institute of MIT and Harvard, told CNN.

"Simply put, what we did was we created the largest human family tree ever," Wohns said. "We have a single genealogy that traces the ancestry of all of humanity, and shows how we're all related to each other today." ...

The resource means anyone who has access to their own genetic information can work out when their ancestors moved to a particular place, and why they have certain genes.

"It's basically understanding the entire story of human history that's written in our genes," Wohns said.
Human genetic research has developed rapidly in recent decades, generating huge amounts of new information. New techniques in ancient DNA analysis have provided tantalizing details about prehistory and in 2010 explosively revealed that humans interbred with Neanderthals.

... As things stand, the genes of 3,609 people from 215 populations have been sequenced, with some dating from more than 100,000 years ago. The method allows for this number to be expanded to potentially millions of genomes in the future.

The paper confirms existing conclusions about human history, including that most human evolution took place in Africa before a large movement out of the continent around 70,000 years ago, Wohns said.
