Scientists Have Created a Device That Sucks Water Out of Thin Air, Even in the Desert

Posted by in categories: materials, sustainability

When it comes to future challenges, one of the biggest will be water scarcity — on a warming planet we’re going to have plenty of seawater, but not enough fresh, clean water in the right places for everybody to drink.

And while a lot of research has focussed on desalination, a team of scientists have now come up with another possible solution — a device that pulls fresh water out of thin air, even in places with humidity as low as 20 percent. All it needs is sunlight.

It might sound too good to be true, but so far the research is solid. Called the ‘solar-powered harvester’, the device was created by teams from MIT and the University of California, Berkeley, using a special type of material known as a metal-organic framework (MOF).

Star Trek’s Tricorder Now Officially Exists Thanks To A Global Competition

Posted by in categories: bioengineering, biotech/medical, holograms

Oscar Wilde once said that life imitates art, and science and engineering is often no exception to this. Science fiction certainly provides science types with plenty of inspiration for inventions, including holograms, teleportation, and even sonic screwdrivers.

Star Trek’s all-purpose medical device, the Tricorder, has also inspired a fair few people to recreate its near-magical ability to instantly diagnose a patient. As it happens, the non-profit X-Prize Foundation were so keen to get one invented that they started a global competition to see if any mavericks would succeed.

New pill considered key in the fight against ageing

Posted by in categories: biotech/medical, life extension

This contains information that is not in other articles on the same topic of David Sinclair:

“The results certainly sound encouraging. Before he started taking a 500mg NMN pill every morning, 47-year-old Professor Sinclair had his blood tested and was told his body had a biological age of 58.

After consuming NMN for three months, he was tested again and his biological age was 32.”

This college dropout says he’s cracked the crucial component for self-driving cars

Posted by in categories: robotics/AI, transportation

Most companies working on autonomous vehicles consider lidar sensors mandatory for vehicles to safely navigate alone and distinguish objects such as pedestrians and cyclists. But the best existing sensors are bulky, extremely expensive, and in short supply as demand surges (see “Self-Driving Cars’ Spinning Laser Problem”). Alphabet and Uber have both said they were forced to invent their own, better-performing sensors from scratch to make self-driving vehicles viable. Luminar hopes to serve automakers that would rather not go to that effort.

Russell doesn’t have a college degree—he dropped out of Stanford in return for a $100,000 check under a program started by venture capitalist Peter Thiel to encourage entrepreneurship. But Russell says a (short) lifetime of tinkering and building with electronics helped him design a new lidar sensor that sees farther and in more detail than those on the market.

AI picks up racial and gender biases when learning from what humans write

Posted by in categories: information science, robotics/AI

Artificial intelligence picks up racial and gender biases when learning language from text, researchers say. Without any supervision, a machine learning algorithm learns to associate female names more with family words than career words, and black names as being more unpleasant than white names.

For a study published today in Science, researchers tested the bias of a common AI model, and then matched the results against a well-known psychological test that measures bias in humans. The team replicated in the algorithm all the psychological biases they tested, according to study co-author Aylin Caliskan, a post-doc at Princeton University. Because machine learning algorithms are so common, influencing everything from translation to scanning names on resumes, this research shows that the biases are pervasive, too.

“Language is a bridge to ideas, and a lot of algorithms are built on language in the real world,” says Megan Garcia, the director of New America’s California branch who has written about this so-called algorithmic bias. “So unless an alg is making a decision based only on numbers, this finding is going to be important.”

NASA: Nearby ocean worlds could be best bet for life beyond Earth

Posted by in category: space

Fascinating stuff!


NASA has new evidence that the most likely places to find life beyond Earth are Jupiter’s moon Europa or Saturn’s moon Enceladus. In terms of potential habitability, Enceladus particularly has almost all of the key ingredients for life as we know it, researchers said.

New observations of these active ocean worlds in our solar system have been captured by two NASA missions and were presented in two separate studies in an announcement at NASA HQ in Washington today.

Synopsis: A Room-Sized Linear Accelerator for Proton Therapy

Posted by in category: biotech/medical

A proton beam can kill cancer cells, and the accelerators used for treatment are always the circular kind. Linear accelerators (“linacs”) allow more control of the beam; for example, the energy can be varied rapidly to match a patient’s breathing. But linacs take up a lot of space. Now researchers propose a design that could fit in a room 10 m x 20 m, potentially making linacs practical for patient therapy. Research from CERN.

NASA’s New Horizons Surprises With Whole New View Of Cosmos

Posted by in category: space travel

New Horizons has made observations it was never tasked with making; serendipity of the sort that may lead to new and better astronomical missions to observe the distant cosmos from the outer fringes of the solar system, where it’s darkest and astronomers would have the clearest, dust-free view of our own galaxy and the optical light from the universe as a whole.


NASA’s New Horizons spacecraft has unexpectedly made observations of optical light from beyond our Milky Way galaxy. Astronomers are ecstatic and hoping for more.
