All Headlines
Scientists just recreated a rare cosmic reaction never seen before
A breakthrough experiment has shed new light on one of astrophysics’ biggest mysteries: the origin of rare proton-rich elements. For the first time, scientists directly measured a key reaction that creates selenium-74 using a rare isotope beam. The results sharpen models of how these elements form in supernova explosions, cutting uncertainty in half. But the findings also reveal gaps in current theories, hinting that the story isn’t complete yet.
Scientists just debunked a 50-year myth about Hawaii’s birds
A new study from the University of Hawaiʻi at Mānoa is overturning a decades-old belief that Indigenous Hawaiians hunted native waterbirds to extinction. Instead, researchers found no scientific evidence supporting this claim and propose a more complex explanation involving climate change, invasive species, and shifts in land use—many occurring before Polynesian arrival or after traditional stewardship systems were disrupted.
Mammal ancestors laid eggs, and this 250-million-year-old fossil finally proves it
In the aftermath of Earth’s most catastrophic extinction event, one unlikely survivor rose to dominate a shattered world: Lystrosaurus. Now, a stunning fossil discovery—an ancient egg containing a curled-up embryo—has finally answered a decades-old mystery about whether mammal ancestors laid eggs. Using advanced imaging technology, scientists confirmed that these resilient creatures did reproduce this way, likely producing large, soft-shelled eggs packed with nutrients.
Scientists discover why bread can cause weight gain without extra calories
Bread and other carbohydrate staples may be doing more than just filling plates—they could be quietly reshaping metabolism. In a surprising twist, researchers found that mice strongly preferred carbs like bread, rice, and wheat, abandoning their regular diet entirely. Even without eating more calories, they gained weight and body fat, not because they overate, but because their bodies burned less energy.
Scientists finally know where the Colorado River’s missing water is going
For years, water managers have been puzzled as the Colorado River kept delivering less water than expected—even when snowpack levels looked promising. New research reveals the missing piece: spring rain, or rather, the lack of it. Warmer, drier springs mean plants are soaking up more snowmelt before it can reach rivers, fueled by sunny skies that boost growth and evaporation. In fact, this shift explains nearly 70% of the shortfall, tying the mystery directly to the long-running Millennium droug
Quantum systems can remember and forget at the same time, scientists discover
Quantum systems can secretly “remember” their past—even when they appear not to. Scientists found that whether a system shows memory depends on how you look at it: through its evolving state or its measurable properties. Each perspective uncovers different kinds of memory, meaning a system can seem memoryless and memory-filled at the same time. This discovery could change how researchers design and control quantum technologies.
New toothpaste stops gum disease without killing good bacteria
Scientists have developed a new way to fight gum disease without wiping out the mouth’s helpful bacteria—a major shift from traditional treatments. Instead of killing everything, this targeted approach blocks only the harmful microbes that drive periodontitis, allowing beneficial bacteria to thrive and restore balance naturally.
This strange “pearling” motion inside cells could change how we understand disease
Mitochondria don’t just generate energy—they also carefully organize their own DNA in a surprisingly elegant way. Scientists have discovered that a long-overlooked phenomenon called “mitochondrial pearling,” where mitochondria briefly form bead-like shapes, helps evenly space clusters of mitochondrial DNA.
The people you live with could be changing your gut bacteria
Spending time with close companions might do more than strengthen bonds—it could also reshape your gut bacteria. In a study of island birds, those with stronger social ties shared more gut microbes, especially types that require direct contact to spread. This suggests that social interaction itself—not just shared space—drives microbial exchange. The same process may be happening in human households through everyday closeness.
Gray whales are entering San Francisco Bay and many aren’t surviving
Gray whales are beginning to break their long-established migration patterns, venturing into risky new territory like San Francisco Bay as climate change disrupts their Arctic food supply. But this unexpected detour is proving deadly: nearly one in five whales that enter the Bay don’t survive, with many struck by ships in the crowded, foggy waters.
Light makes plants stronger but also holds them back
Light doesn’t just help plants grow—it may also quietly hold them back. Researchers have uncovered a surprising mechanism where light strengthens the “glue” between a plant’s outer skin and its inner tissues. This tighter bond, driven by a compound called p-coumaric acid, reinforces cell walls but also restricts how much the plant can expand. The discovery reveals a hidden balancing act: light both fuels growth and subtly puts the brakes on it.
Stanford scientists discover “natural Ozempic” without side effects
A newly discovered molecule could reshape the future of weight loss treatments by mimicking the powerful appetite-suppressing effects of drugs like Ozempic — but without many of the unpleasant side effects. Identified using artificial intelligence, this tiny peptide, called BRP, appears to act directly on the brain’s appetite-control center, helping animals eat less and lose fat without nausea or muscle loss.
