Wildfires are becoming more intense and dangerous, but a new Stanford-led study offers hope: prescribed burns—intentionally set, controlled fires—can significantly lessen their impact. By analyzing satellite data and smoke emissions, researchers found that areas treated with prescribed burns saw wildfire severity drop by 16% and smoke pollution fall by 14%. Even more striking, the smoke from prescribed burns was just a fraction of what wildfires would have produced in the same areas.
Buried for 23,000 years: These footprints are rewriting American history (link is external)
Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago — much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third line of evidence pointing to this revised timeline.
Scientists reveal a spontaneous reaction that could have started life (link is external)
Scientists have uncovered a surprising new way that urea—an essential building block for life—could have formed on the early Earth. Instead of requiring high temperatures or complex catalysts, this process occurs naturally on the surface of tiny water droplets like those in sea spray or fog. At this boundary between air and water, a unique chemical environment allows carbon dioxide and ammonia to combine and spontaneously produce urea, without any added energy. The finding offers a compelling clue in the mystery of life’s origins and hints that nature may have used simple, everyday phenomena to spark complex biological chemistry.
New Orleans is sinking—and so are its $15 billion flood defenses (link is external)
Parts of New Orleans are sinking at alarming rates — including some of the very floodwalls built to protect it. A new satellite-based study finds that some areas are losing nearly two inches of elevation per year, threatening the effectiveness of the city's storm defenses.
A giant pulse beneath Africa could split the continent — and form an ocean (link is external)
Beneath the Afar region in Ethiopia, scientists have discovered pulsing waves of molten rock rising from deep within the Earth — a geological heartbeat that could eventually split Africa in two. These rhythmic surges of mantle material are helping to stretch and thin the continent’s crust, setting the stage for a new ocean to form in millions of years. The pulses aren’t random: they follow patterns shaped by the tectonic plates above, behaving differently depending on how thick the plates are and how fast they’re spreading.
NASA discovers link between Earth’s core and life-sustaining oxygen (link is external)
For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking link between deep-Earth processes and life at the surface, suggesting that the planet’s churning molten interior could be subtly shaping the conditions for life. By comparing ancient magnetic records with atmospheric data, researchers found that these two seemingly unrelated phenomena have danced together since the Cambrian explosion, when complex life first bloomed. This tantalizing connection hints at a single, hidden mechanism — perhaps even continental drift — orchestrating both magnetic strength and the air we breathe.
Only 3 years left: The carbon budget for 1. 5 °C is almost gone (link is external)
At current emission rates, we re just over three years away from blowing through the remaining carbon budget to limit warming to 1.5 C. This new international study paints a stark picture: the pace of climate change is accelerating, seas are rising faster than ever, and the Earth is absorbing more heat with devastating consequences from hotter oceans to intensified weather extremes.

Remove the top male spotty fish and, within minutes, the next-in-line female morphs into the tank s new tyrant charging and nipping rivals while her body quietly begins a weeks-long transition to male.
These 545-million-year-old fossil trails just rewrote the story of evolution (link is external)
A groundbreaking study suggests that the famous Cambrian explosion—the dramatic burst of diverse animal life—might have actually started millions of years earlier than we thought. By analyzing ancient trace fossils, researchers uncovered evidence of complex, mobile organisms thriving 545 million years ago, well before the traditionally accepted timeline. These early creatures likely had segmented bodies, muscle systems, and even directional movement, signaling a surprising level of biological sophistication. Their behavior and mobility, preserved in fossil trails, offer new insight into how complex life evolved, potentially rewriting one of the most important chapters in Earth’s evolutionary history.
Tiny creatures, massive impact: How zooplankton store 65 million tonnes of carbon annually (link is external)
Zooplankton like copepods aren’t just fish food—they’re carbon-hauling powerhouses. By diving deep into the ocean each winter, they’re secretly stashing 65 million tonnes of carbon far below the surface, helping fight climate change in a way scientists are only just starting to understand.
This breakthrough turns old tech into pure gold — No mercury, no cyanide, just light and salt (link is external)
At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on trace gold in scientific waste. Tested on everything from circuit boards to mixed-metal ores, the approach offers a promising solution to both the global gold rush and the growing e-waste crisis. The technique could be a game-changer for artisanal miners and recyclers, helping recover valuable metals while protecting people and the planet.
Why cats prefer sleeping on their left side—and how it might help them survive (link is external)
Cats overwhelmingly choose to sleep on their left side, a habit researchers say could be tied to survival. This sleep position activates the brain’s right hemisphere upon waking, perfect for detecting danger and reacting swiftly. Left-side snoozing may be more than a preference; it might be evolution’s secret trick.
Can these endangered lizards beat the heat? Scientists test bold relocation plan (link is external)
South Australia’s tiny pygmy bluetongue skink is baking in a warming, drying homeland, so Flinders University scientists have tried a bold fix—move it. Three separate populations were shifted from the parched north to cooler, greener sites farther south. At first the lizards reacted differently—nervous northerners diving for cover, laid-back southerners basking in damp burrows—but after two years most are settling in, suggesting they can ultimately thrive.
Skull study shows Chicago's rodents are rapidly evolving (link is external)
Urban wildlife is evolving right under our noses — and scientists have the skulls to prove it. By examining over a century’s worth of chipmunk and vole specimens from Chicago, researchers discovered subtle yet significant evolutionary changes in these rodents’ skulls, seemingly in response to city life.
Scientists finally know why early human migrations out of Africa failed (link is external)
New research reveals why early human attempts to leave Africa repeatedly failed—until one group succeeded spectacularly around 50,000 years ago. Scientists discovered that before this successful migration, humans began using a much broader range of environments across Africa, from dense forests to harsh deserts. This ecological flexibility, developed over thousands of years, gave them the adaptive edge needed to survive the more difficult exit routes into Eurasia.
New test unmasks illegal elephant ivory disguised as mammoth (link is external)
Poachers are using a sneaky loophole to bypass the international ivory trade ban—by passing off illegal elephant ivory as legal mammoth ivory. Since the two types look deceptively similar, law enforcement struggles to tell them apart, especially when tusks are carved or polished. But scientists may have found a powerful new tool: stable isotope analysis.
Farming without famine: Ancient Andean innovation rewrites agricultural origins (link is external)
Farming didn t emerge in the Andes due to crisis or scarcity it was a savvy and resilient evolution. Ancient diets remained stable for millennia, blending wild and domesticated foods while cultural innovations like trade and ceramics helped smooth the transition.
This team tried to cross 140 miles of treacherous ocean like stone-age humans—and it worked (link is external)
Experiments and simulations show Paleolithic paddlers could outwit the powerful Kuroshio Current by launching dugout canoes from northern Taiwan and steering southeast toward Okinawa. A modern crew proved it, carving a Stone-Age-style canoe, then paddling 225 km in 45 hours guided only by celestial cues—demonstrating our ancestors’ daring and mastery of the sea.
New viruses discovered in bats in China could be the next pandemic threat (link is external)
Two newly discovered viruses lurking in bats are dangerously similar to Nipah and Hendra, both of which have caused deadly outbreaks in humans. Found in fruit bats near villages, these viruses may spread through urine-contaminated fruit, raising serious concerns. And that’s just the start—scientists found 20 other unknown viruses hiding in bat kidneys.
Mammals didn't walk upright until late—here's what fossils reveal (link is external)
The shift from lizard-like sprawl to upright walking in mammals wasn’t a smooth climb up the evolutionary ladder. Instead, it was a messy saga full of unexpected detours. Using new bone-mapping tech, researchers discovered that early mammal ancestors explored wildly different postures before modern upright walking finally emerged—much later than once believed.
