New Kind of ‘Solar’ Cell Shows We Can Generate Electricity Even at Night

New Kind of 'Solar' Cell Shows We Can Generate Electricity Even at Night

Conventional solar technology soaks up rays of incoming sunlight to bump out a voltage. Strange as it seems, some materials are capable of running in reverse, producing power as they radiate heat back into the cold night sky. A team of engineers in Australia has now demonstrated the theory in action, using the kind of … Read more

Extraterrestrial Stone Found in Egypt May Be First Evidence on Earth of Rare Supernova

Extraterrestrial Stone Found in Egypt May Be First Evidence on Earth of Rare Supernova

‘Standard candle’ (or type Ia) supernova explosions are some of the most energetic events in the Universe, happening when a dense white dwarf star subsumes another star. Now, scientists think they’re found the first evidence on Earth of such a supernova. The claim comes after a careful study of the extraterrestrial Hypatia stone that was … Read more

‘Smart’ Contact Lens Could Help Treat a Leading Cause of Blindness, Scientists Say

'Smart' Contact Lens Could Help Treat a Leading Cause of Blindness, Scientists Say

A flexible contact lens that senses eye pressure and releases a drug on-demand could help treat glaucoma, the second leading global cause of blindness worldwide. The compact wireless device, which has been developed by a team of Chinese researchers and tested in pig and rabbit eyes so far, appears to detect and reduce rising eye … Read more

Over 1,000 New Asteroids Discovered Hidden in Hubble Archives

Over 1,000 New Asteroids Discovered Hidden in Hubble Archives

Researchers have found over 1,700 asteroid trails in archived Hubble data from the last 20 years. While many of the asteroids are previously known, more than 1,000 are not. What good are another 1,000 asteroids? Like all asteroids, they could hold valuable clues to the Solar System’s history. As time passes and more and more … Read more

The Ghostly Sounds of Auroras Can Be Heard, Even When They’re Invisible

The Ghostly Sounds of Auroras Can Be Heard, Even When They're Invisible

If you’re up high, and you listen carefully on nights when the northern sky dances with blazing sheets of green light – Earth’s spectacular aurora borealis – you might hear some ghostly sounds. Almost imperceptible, the sounds had only been heard during the wildest aurora displays, described as rushing sounds, like a waterfall at a … Read more

Potentially Alive 830-Million-Year-Old Organisms Found Trapped in Ancient Rock

Potentially Alive 830-Million-Year-Old Organisms Found Trapped in Ancient Rock

An incredible discovery has just revealed a potential new source for understanding life on ancient Earth. A team of geologists has just discovered tiny remnants of prokaryotic and algal life – trapped inside crystals of halite dating back to 830 million years ago. Halite is sodium chloride, also known as rock salt, and the discovery … Read more

Survey of More Than 800 Planet-Forming Disks Reveals a Planetary Evolution Surprise

Survey of More Than 800 Planet-Forming Disks Reveals a Planetary Evolution Surprise

Is our Solar System comparable to other solar systems? What do other systems look like? We know from exoplanet studies that many other systems have hot Jupiters, massive gas giants that orbit extremely close to their stars. Is that normal, and our Solar System is the outlier? One way of addressing these questions is to … Read more

A Never-Before-Seen Mimicry Trick Has Just Been Recorded in Buzzing Bats

A Never-Before-Seen Mimicry Trick Has Just Been Recorded in Buzzing Bats

Scientists have discovered a clever mimicry trick used by some bats: they’ll buzz like hornets when they think they’re under threat from predators, giving the sonic impression they’re more dangerous than they actually are. It’s the first time behavior like this has been recorded in mammals, but it happens elsewhere in the animal kingdom – … Read more

For The First Time, Scientists Have Grown Plants in Moon Dirt. It Didn’t Go Great

For The First Time, Scientists Have Grown Plants in Moon Dirt.  It Didn't Go Great

When the Artemis program returns humans to the Moon in (hopefully) a few years’ time, there are considerable logistics that need to be addressed for keeping such fragile beings alive in such a hostile environment. Not least is the issue of food. Space agencies involved in the International Space Station are very experienced, by now, … Read more

There’s a Major Issue With How We Treat Lab Mice, And It Could Affect Study Results

There's a Major Issue With How We Treat Lab Mice, And It Could Affect Study Results

Over 120 million laboratory rats and mice are used worldwide each year. Many are used to study distressing conditions like cancer, arthritis and chronic pain, and nearly all spend their lives in small, empty box-like cages: a kind of permanent lockdown. Our new analysis shows that this restrictive, artificial housing causes rats and mice to … Read more
