Satellites spot rapid “Doomsday Glacier” collapse

8:05
Two decades of satellite and GPS data show the Thwaites Eastern Ice Shelf slowly losing its grip on a crucial stabilizing point as fractures multiply and ice speeds up. Scientists warn this pattern could spread to other vulnerable Antarctic shelves.

A lost Amazon world just reappeared in Bolivia

6:26
Researchers exploring Bolivia’s Great Tectonic Lakes discovered a landscape transformed over centuries by sophisticated engineering and diverse agricultural traditions. Excavations show how Indigenous societies adapted to dynamic wetlands through raised fields, canals, and mixed livelihoods. Today’s local communities preserve this biocultural continuity, guiding research and conservation.

Fructose may quietly supercharge your inflammation

6:26
Researchers found that fructose can prime immune cells to overreact to bacterial toxins. In healthy adults, fructose-sweetened drinks increased receptors that trigger inflammation. This heightened sensitivity may contribute to greater infection risk. The effects could be even more dangerous in people with metabolic diseases.

New 3D scan reveals a hidden network of moai carvers on Easter Island

17:13
A high-resolution 3D model of Rano Raraku shows that the moai were created in many distinct carving zones. Instead of a top-down system, the statues appear to have been produced by separate family groups working independently while sharing techniques. Evidence of varied carving styles and multiple transport routes supports this decentralized picture. The results challenge old assumptions about ho…

Scientists discover a hidden brain circuit that rewrites vision

17:13
MIT scientists found that what we see is strongly influenced by how alert or active we are. Parts of the brain responsible for planning and control send specialized signals that either boost or quiet visual details. These areas seem to balance each other, sharpening important information while dimming distractions. The study shows vision is constantly being shaped by our internal state.

Your skin has a built-in cancer defense and sunlight turns it off

17:13
Scientists have uncovered how too much sunlight can flip a hidden switch inside skin cells that makes inflammation spiral out of control and increases the risk of cancer. Their research reveals that UV radiation breaks down a protective protein called YTHDF2, which normally prevents a small RNA signal from activating an immune sensor linked to dangerous inflammation. Once that protection is lost,…

Scientists find a hidden obesity trigger in soybean oil

17:13
Researchers at UC Riverside have uncovered why soybean oil, one of America's most widely consumed ingredients, drives significant weight gain—at least in mice. The findings point not to the oil itself but to the fat-derived molecules it produces inside the body, called oxylipins, which can trigger inflammation, alter liver function, and influence genes tied to metabolism.

A backwards Bible map that changed the world

17:13
Five hundred years ago, a Bible accidentally printed with a backwards map of the Holy Land sparked a revolution in how people imagined geography, borders, and even nationhood. Despite the blunder, the map reshaped the Bible into a Renaissance book and spread new ideas about territorial organization as literacy expanded. Over time, sacred geography evolved into political boundary-making, influenci…

Why some memories last a lifetime while others fade fast

30.listopadu
Scientists have uncovered a stepwise system that guides how the brain sorts and stabilizes lasting memories. By tracking brain activity during virtual reality learning tasks, researchers identified molecules that influence how long memories persist. Each molecule operates on a different timescale, forming a coordinated pattern of memory maintenance. The discoveries reshape how scientists understa…

Scientists find coastal seas acidifying shockingly fast

30.listopadu
New findings show that some coastal regions will become far more acidic than scientists once thought, with upwelling systems pulling deep, CO2-rich waters to the surface and greatly intensifying acidification. Historic coral chemistry and advanced modeling reveal that these regions are acidifying much faster than expected from atmospheric CO2 alone, raising serious concerns for fisheries, marine …

242-million-year-old mini predator changes lizard evolution

30.listopadu
A tiny 242-million-year-old fossil from Devon is shaking up scientists’ assumptions about the earliest members of the lizard lineage. Instead of the expected skull hinges and palate teeth typical of modern lizards and snakes, this ancient creature shows a surprising mix of primitive and unusual traits—along with strikingly large, blade-like teeth. High-resolution synchrotron scans revealed detail…

Simple thyroid check in pregnancy may lower autism risk

30.listopadu
Researchers have found that ongoing thyroid hormone imbalance in pregnancy may be linked to higher autism risk in children. Treated thyroid disorders did not show the same effect. The longer the imbalance lasted across trimesters, the more the risk appeared to rise. The study underscores the need for consistent thyroid monitoring.

Scientists discover hidden wolf DNA in most dogs

30.listopadu
Researchers studying thousands of canine genomes discovered that wolf DNA is still present in most dog breeds. This ancient genetic influence shows up in traits like body size, behavior, and environmental resilience. Even dogs bred far from wolves, including tiny chihuahuas, carry detectable wolf ancestry. The findings highlight how deeply intertwined the histories of dogs and wolves really are.

Dinosaur mummy found with hooves and a hidden crest

30.listopadu
Scientists have reconstructed the most complete and lifelike profile of Edmontosaurus annectens thanks to an extraordinary preservation process called clay templating, in which a thin clay film captured the dinosaur’s skin, scales, spikes, and even hooves in three dimensions. By combining newly excavated “mummies,” advanced imaging, and artistic reconstruction, researchers revealed a tall crest, …

Scientists just teleported information using light

30.listopadu
Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots—one of the biggest challenges in building a quantum internet. By creating nearly identical semiconductor-based photon sources and using frequency converters to sync them, researchers successfully transferred quantum states across a fiber link, proving a…
