Einstein Probe may have caught a black hole tearing apart a white dwarf for the first time
Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in its earliest moments, revealing an unusual sequence of intense X-ray flashes unlike anything seen in a typical gamma-ray burst.
After 70 years of excavation, ancient Sardis becomes a UNESCO World Heritage site
After nearly seven decades of excavation, the legendary ancient city of Sardis has become a UNESCO World Heritage Site, celebrating years of discoveries that continue to reshape its history. Archaeologists say the biggest breakthroughs don't happen in a single season—they emerge as decades of evidence slowly come together.
Earth may have been seeding Venus with life for billions of years
A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—it may have come from Earth.
NASA’s Lucy finds a wobbling peanut-shaped asteroid with signs of ancient water
NASA’s Lucy spacecraft discovered that asteroid Donaldjohanson is a wobbling, peanut-shaped relic born from a violent collision and slowly reshaped by the subtle force of sunlight. It also carries traces of ancient water, making it an important clue to the solar system’s mysterious past.
Scientists discover ancient brain cells that help block distractions
Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mice, the animals became unusually distractible—similar to what is seen in ADHD—but regained normal focus as soon as the neurons were reactivated.
The universe may be hiding conscious minds stranger than we can imagine
What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastness of the universe and the likely existence of countless alien civilizations, they suggest it would be surprisingly Earth-centric to assume that only Earth-like biology can support conscious experience.
Early humans were bringing fire into caves 1.8 million years ago
A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was likely carried in and maintained by human ancestors. The discovery pushes back the timeline for fire use and reveals surprisingly sophisticated behavior long before humans could create fire on demand.
This common vitamin deficiency can mimic normal aging
Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly. This could explain why some people experience fatigue and brain fog even before traditional signs of deficiency show up.
Why South Africa’s leopards shrank to half their normal size
A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after being isolated for roughly 20,000 years. Surprisingly, despite their small population, they have retained much of their genetic diversity.
Researchers discover why fructose doesn't satisfy hunger like glucose
A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High-fructose corn syrup triggered a stronger response and was preferred by the animals. The findings suggest that the type of sugar—not just the calories—can influence appetite and food preferences.
Scientists just discovered how queen bees are really made
For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen. New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax, carefully regulate warmth and humidity, and dedicate entire teams of attendants to raising future queens.
Scientists discover hidden “footprints of death” that may help viruses spread
Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny “footprints of death” packed with newly discovered particles that help guide the immune system to clean up the remains. But researchers found that influenza viruses can exploit this process, hiding inside these microscopic packages and potentially using them to spread to nearby cells.
