Underground dome house of the family who led geese to fly home

Posted by in categories: existential risks, transportation

Paula and Bill Lishman spent many winters in a poorly-insulated A-frame cabin before realizing they needed to go underground to use the earth’s energy to stay warm, so they knocked the top off a hill, dropped in ferro-cement domes, and covered it up again with dirt.

Thanks to skylights cut into every dome and the white-powdered marble that covers the interior, their earth-sheltered home is naturally well-lit despite being below the frost line.

Asteroid mining: SpaceX will help a startup launch operations in 2023

Posted by in categories: materials, space travel

The space tech startup, AstroForge, hopes to complete two proof-of-concept missions this year using SpaceX rockets.

In what might be a groundbreaking moment in space industry history, a new startup plans to launch not one but two space missions this year. This might not sound like a big deal, but the company wants to go into space to find and use minerals from asteroids and other deep-space objects.

Watch a sea cucumber-inspired shapeshifting robot escape jail

Posted by in categories: materials, robotics/AI

It can even liquefy and move through small spaces, just like T-1000 in Terminator 2.

An international team of scientists created sea cucumber-inspired miniature robots that can quickly shift between liquid and solid states.

They built the new robots with a material they dubbed a “magnetoactive solid-liquid phase transitional machine.” The robots are also magnetic and can conduct electricity, as per a press release.

First nuclear-powered Bitcoin mine to start operations in US this year

Posted by in categories: bitcoin, computing, nuclear energy, sustainability

This will reduce carbon emissions from mining operations but is that the only way?

TeraWulf, a Minnesota-headquartered company, will become the first entity in the U.S. to power its Bitcoin mining operations with nuclear energy, CNET.

Researchers broke the record for the shortest pulse of electrons ever

Posted by in category: computing

They produced a signal a mind-bending short 53 billionths of a second.

A team of scientists broke the record for the shortest pulse of electrons ever created. They produced a signal a mere 53 attoseconds long. That’s a mind-bending short 53 billionths of a second.

The researchers say their new achievement could lead to more accurate electron microscopes and could also speed up data transmission in computer chips, as per an institutional press release.

Green comet’s new “anti-tail” seemingly breaks the laws of physics

Posted by in categories: cosmology, physics

Astrophotographers spotted what looks like a third tail flowing in front of, instead of behind, the glowing comet.

The green comet C/2022 E3 (ZTF), which last flew by Earth 50,000 years ago when Neanderthals still coexisted with humans, has been gradually making its way across the night sky over the last few days.

What’s more, as per a LiveScience report, this “anti-tail” appears to be flowing in the wrong direction and is, therefore, seemingly breaking the laws of physics.

Metal alloys may support nuclear fusion energy

Posted by in categories: business, nuclear energy

The research is a huge milestone towards fusion energy that can power millions of homes and businesses with a carbon-neutral energy source.

Researchers at the Lawrence Livermore National Laboratory announced that they observed a net gain in nuclear fusion energy for the very first time at the end of 2022. The research is a huge milestone towards fusion energy that can power millions of homes and businesses with a carbon-neutral energy source. However, converting this achievement into a practical nuclear energy source requires innovative technologies to bring fusion-powered society to life.

Can humans still grow fur? New study discovers the genes

Posted by in categories: evolution, genetics

An examination of 19,149 mammalian genes sheds new light on the future of hair loss.

Due to evolution, we got rid of most of the hair on our bodies. Although we are mammals, it is obvious that we are less hairy than the majority of them. So, could this mean we are on our way to becoming more hairless? Or is there a way to turn hair development back on?

This is where a new study comes in. As stated by the University of Utah, a groundbreaking comparison of genetic codes from 62 animals is beginning to tell the story of how humans—and other mammals—came to be, naked. The study was published in the journal eLife.

VEXAS: Mysterious disease with high mortality rate detailed in study

Posted by in categories: biotech/medical, health

Nearly 15,500 people in the U.S. over age 50 are estimated to have VEXAS syndrome.

A rare disorder called VEXAS syndrome has bemused the United States’ health services since 2020. The syndrome was a great mystery until the researchers’ work yielded results.

As stated by NYU Langone Health, with up to 50 percent of sufferers, mostly men, passing away within five years of diagnosis, this illness has a significant mortality rate.
