Recent studies have shown tire emissions to be a larger threat to global health than anyone realized—and EVs could make the problem worse.

Scientists have captured the fleeting moment when a heart starts beating, a feat made all the more remarkable when you consider the relative brevity of a zebrafish’s life.

In a tight window about 20 hours into zebrafish development, the embryos’ developing hearts jumped into action, emerging as one from an ensemble of single cells.

“It was like somebody had flipped on a switch,” says Harvard University biophysicist Adam Cohen, senior author of the new study, which imaged zebrafish embryos snug in custom-made agarose molds to capture this once-in-a-lifetime event.

In a new study, self-sustaining chemical reactions were discovered which carry the potential to support alien life, which is very different from the elements present on Earth.

The biology of Earth hinges on organic compounds which comprise carbon along with elements like phosphorus, sulphur, nitrogen, oxygen and hydrogen. Scientists believe that alternative chemical frameworks can lead to the existence of alien life forms.

For long, scientists have wondered if alien life might evolve on the basis of significantly different chemistry. Researchers have speculated if silicon may work as a backbone for biology.

The discovery made using NASA’s powerful space telescope brings scientists a step closer to determining if the salty water oceans of Europa could support life.

Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers.

Ever wondered what the Sun looked like in its infancy?

A new image from NASA’s James Webb Space Telescope has captured what Earth’s sun looked like when it was only a few tens of thousands of years old.

(WTAJ) — Astronomers using the James Webb Space Telescope say they have stumbled onto possible signs of life coming from a massive Earth-like exoplanet, NASA confirmed in a release.

K2-18 b is an exoplanet — a planet outside our solar system — that’s 8.6 times as massive as Earth. A new investigation with the JWST revealed the presence of “carbon-bearing molecules” that include methane and carbon dioxide. The findings add to recent studies that suggest that K2-18 b could be a Hycean exoplanet, meaning it has the potential to hold a hydrogen-rich atmosphere and a water-covered surface, NASA reported.

Astronomers first studied K2-18 b’s atmosphere with NASA’s Hubble Space Telescope in 2019. The results prompted further studies of the massive exoplanet that have changed experts understanding of the system.

On Earth, only living things make dimethyl sulfide molecules. NASA’s James Webb Space Telescope just found hints of it in another world.

For a few hours after a star smashes into a supermassive black hole, some of the brightest light in the Universe is produced.

The subsequent flash of radio waves were thought to simmer down within weeks or months of a collision. It turns out we might have been a little impatient to turn our gaze elsewhere.

An international team of astrophysicists has witnessed radio waves bursting from material surrounding an assortment of supermassive black holes hundreds of days after they ripped apart a star, suggesting many collisions could be responsible for a serious case of cosmic indigestion.

With the emergence of AI, researchers are diving into the capabilities of these large language models, and one researcher has found intent for deception.
