Radio images suggest a link between Betelgeuse’s changing outline and its companion’s expected orbit, offering clues to how a smaller star may influence a giant’s later life. Betelgeuse, the bright red supergiant marking Orion’s shoulder, may have another star stirring its atmosphere from within. Its recently identified companion, Siwarha, is thought to orbit at a […]
A Black Hole Could Split in Two, According to a Surprising New Theory
Black holes might split in two under extreme conditions, theoretical calculations suggest, offering physicists a way to explore the limits of our understanding of gravity. Two black holes can collide and merge into one. But could a single black hole divide into two smaller ones that go their separate ways? Reversing a merger might sound […]
Study Reveals How Brain Function Changes When We Learn Something New
A beginner’s violin lesson may seem worlds apart from dementia research, yet wearable brain scans are revealing signals that could help scientists understand both learning and neurological disease. Playing a familiar tune on a violin is no simple task for someone who has never held the instrument. Each movement must produce the intended sound, and […]
A Hidden Cancer-Fighting Switch Could Supercharge the Human Immune System
Temporarily activating a protein best known for preventing cancer helped engineered human immune cells kill melanoma cells more effectively in the lab, suggesting a way to improve existing cell therapies. Engineering a patient’s immune cells to recognize cancer does not guarantee that they will keep fighting it. Repeated exposure to cancer can gradually weaken T […]
Scientists Sound the Alarm As Colorectal Cancer Reverses a 20-Year Decline
After decades of decline, colorectal cancer rates are showing a concerning reversal. Colorectal cancer rates in the United States are rising across a much wider range of ages than previously recognized, reversing a long period of declining diagnoses. A new study published in NEJM Evidence found that the increase is no longer concentrated among adults […]

New Research Reveals That Honey Beehives Act as a Living Immune System
Scientists have discovered that honey beehives possess a surprisingly sophisticated system for protecting colonies against disease. A honey bee colony relies on more than its workers to fight disease. The hive itself acts as a “living immune system,” using carefully arranged natural materials to create layers of antimicrobial protection around developing bees and stored food. […]
“Schrödinger’s Penguin”: Scientists Discover a Bizarre Paradox Among Endangered Penguins
Endangered erect-crested penguins are holding steady on tiny islands while declining on a breeding ground 40 times larger, challenging assumptions about where the species’ best hope for survival lies. An endangered penguin species could receive a less severe global risk rating even as one of its only two breeding populations suffers a steep decline. A […]
A Devastating Disease Is Threatening the World’s Chocolate Supply – but Scientists May Have Found the Answer
A change to just two DNA letters reduced disease in cacao by about 42% under laboratory conditions, suggesting a possible way to protect future chocolate harvests. Black pod disease is estimated to reduce cacao yields by roughly 30% worldwide, threatening the livelihoods of farmers who grow the crop used to make chocolate. Shifting weather patterns […]
Researchers Discover Earth May Have Made Its Own Water 4.5 Billion Years Ago
Laboratory experiments suggest that rocky planets could generate their own water as they form, potentially giving distant worlds an essential ingredient for life. Rocks, hydrogen gas, and intense heat might sound like an unlikely recipe for an ocean. Yet experiments suggest that these ingredients could have produced much of Earth’s water while the planet was […]
