A single, small molecule can restore muscle strength, fuel brain cell growth and reduce inflammation in old mice, new research shows. So far, the anti-aging molecule has only been tested in rodents and in human cells in lab dishes. But the researchers say the results are compelling enough to move the compound toward human trials, … Read more
A new study has claimed that we may breach the 2 degrees Celsius (3.6 degrees Fahrenheit) climate change increase threshold by the late 2020s — almost two decades earlier than current projections. The study, published Feb. 5 in the journal Nature Climate Change, claims global surface temperatures had increased by 1.7 C (3 F) above … Read more
Using a new machine-learning algorithm, scientists have picked up eight extraterrestrial signals that seem to bear the hallmarks of technology. The research, published Jan. 30 in the journal Nature Astronomy, doesn’t claim to have really found proof of intelligent aliens; a brief follow-up search for the signals detected in the study turned up only silence. … Read more
New research has debunked a controversial 2020 study that claimed to have found the chemical phosphine in Venus’ hellish atmosphere. The chemical’s reported existence had hinted that there was alien life on the planet. In 2020, a team of researchers announced that they had found phosphine in Venus’ atmosphere using data collected by the Japanese … Read more
As Elton John once sang, “Mars ain’t the kind of place to raise your kids; in fact, it’s cold as hell.” But new research suggests that Martian chill could allow bacteria to survive for up to 280 million years below the planet’s surface. The finding raises hopes that traces of ancient life — or even … Read more
Researchers studying the aftermath of a gargantuan black hole collision may have confirmed a gravitational phenomenon predicted by Albert Einstein a century ago. According to new research published today (Oct. 12) in the journal Nature (opens in new tab), the phenomenon — which is known as precession and is similar to the wobbling motion sometimes … Read more
Somewhere out there, there’s probably a person who has your face. And this unrelated look-alike may have more in common with you than appearances, a new study suggests. The surprising research, based on 32 pairs of unrelated doppelgängers from around the world, shows that two people who have a strong facial similarity to each other … Read more
Imagine a spider hanging from a silky thread, as still as a corpse, until its eight legs unexpectedly tremble. While this might sound like a horror movie, it’s actually a nightly experience for jumping spiders (Evarcha arcuate) who can reach rapid eye movement (REM) sleep, the stage in which most dreaming occurs, a new study … Read more
The Milky Way is home to millions of potentially habitable planets — and approximately four of them may harbor evil alien civilizations that would invade Earth if they could, new research posted to the preprint database arXiv (opens in new tab) suggests. The new paper, which has not yet been peer-reviewed, poses a peculiar question: … Read more
After nearly 13.8 billion years of nonstop expansion, the universe could soon grind to a standstill, then slowly start to contract, new research published in the journal Proceedings of the National Academy of Sciences suggests. In the new paper, three scientists attempt to model the nature of dark energy — a mysterious force that seems … Read more
