Want to pretend to live on Mars? For a whole year? Apply now

Posted by in categories: habitats, space travel

Want to find your inner Matt Damon and spend a year pretending you are isolated on Mars? NASA has a job for you.

To prepare for eventually sending astronauts to Mars, NASA began taking applications Friday for four people to live for a year in Mars Dune Alpha. That’s a 1,700-square-foot Martian habitat, created by a 3D-printer, and inside a building at Johnson Space Center in Houston.

New tool maps cell types in lab-grown blobs of brain tissue

Posted by in categories: genetics, mapping, neuroscience

A new tool helps researchers explore the types of cells that make up brain organoids — clusters of cells that can mimic the basic structure, function and development of different parts of the brain.

The software, detailed in Cell Stem Cell, maps information about when and where genes are expressed in brain organoids onto a reference atlas of the developing mouse brain. Scientists can use the resulting overlay to develop organoids that better recapitulate the developing brain, the team says, or to uncover the effects of gene mutations and other experimental perturbations.

Brain organoids derived from the cells of people with conditions such as autism have proved useful in capturing neuronal abnormalities. But the findings are muddied by methodological differences in how researchers develop these lab-grown blobs. Advanced techniques to profile gene expression in single cells have made it easier to identify the cell types in any given organoid. But it’s remained difficult to map those cell types onto different brain regions.

Eye test may help diagnose long COVID

Posted by in category: futurism

In previous research, the researchers behind the present study analyzed nerve fiber damage in people’s corneas and linked this to neuropathy and fibromyalgia.


A recent study concludes that the loss of nerve fibers and an increase of immune cells in the cornea may have associations with long COVID.

China unveils 600 km/h Transrapid train

Posted by in category: transportation

CHINA’S NEW 600 KM PER HOUR LEVITATED TRAIN is the next step in its system of 38,000 km of high speed rail lines covering the nation. China’s land area is almost exactly the same as the USA’s, but, by contrast, the USA has ZERO km of high speed rail. China is financing this and other massive infrastructural networks in the same way that the US formerly financed all its major infrastructure— with governmental financing. Every highway, every railway system, every waterway, etc., etc., in the USA was built in the same way, but we stopped building such systems.


It’s fast, very fast.

In fact, it is the fastest train the world.

For AI to grow up, it needs to learn on its own

Posted by in category: robotics/AI

AI is already pretty powerful when humans show it what to do. As it gets better at drawing smart conclusions on its own, the technology will enter a new “age of self.”

Musk: ‘Dream come true’ to see fully stacked SpaceX Starship rocket during prep for orbital launch

Posted by in categories: Elon Musk, space travel

Elon Musk’s SpaceX stacked a Starship prototype rocket on top of a Super Heavy rocket booster for the first time Friday morning, giving a look at the scale of the combined nearly 400-foot-tall vehicle.

Musk, asked by CNBC what he thought of witnessing the milestone at the company’s facility in Boca Chica, Texas, responded simply.

“Dream come true,” Musk replied in a tweet.

Gene Targets of Stress Hormones in the Brain Identified

Posted by in category: neuroscience

Summary: Study reveals a link between corticosteroid receptors and genes associated with ciliary and neuroplasticity in the hippocampus, an area of the brain associated with stress response, learning, and memory.

Source: University of Bristol.

Chronic stress is a well-known cause of mental health disorders. New research has moved a step forward in understanding how glucocorticoid hormones (‘stress hormones’) act upon the brain and what their function is. The findings could lead to more effective strategies in the prevention and treatment of mental health disorders.

Urban eVTOL announces Leo, a 250-mph hypercar for the skies

Posted by in category: futurism

An electric propulsion specialist and a supercar designer have partnered up on an eye-catching three-seat eVTOL, claiming 250-mph (400 km/h) top speeds and extraordinary 300-mile (483-km) range figures, as well as some extreme flight dynamics and some nifty ideas.

Pete Bitar has been working on vertical propulsion systems for decades now. He’s got a DARPA contract to develop his electric jetpack designs, his Verticycle is a competitor in the GoFly personal flight challenge, and he’s just won one of nine NASA “Future-Scaping Our Skies” awards for his work on ground infrastructure and air traffic control for the coming eVTOL age.

Now he’s partnered up with automotive designer Carlos Salaff to start an eVTOL company. Salaff was behind the outrageous Mazda Furai concept, and has in more recent years been showing his own outrageous coach-built creations at events such as Pebble Beach.
