Phys.org / Dynamic catalyst interfaces offer a smarter route for converting CO₂ into formic acid
Electroreduction offers a promising route for converting CO2 into value-added chemicals using renewable electricity. Among the possible products, formic acid is particularly attractive because it is an important chemical ...
Science X / An ancient quantum machine controls our immune system—and researchers just discovered how it works
Our immune system is much older than we think. Long before dinosaurs existed, early life forms had developed a powerful defense system. Innate immunity has existed since the Cambrian period—that is, since the time when almost ...
Medical Xpress / Testosterone suppresses brain tumor growth in males, study suggests
In a new study, scientists at Cleveland Clinic discovered that hormones associated with male development may play a key role in limiting the growth of brain tumors in men. The research team found that the loss of androgen ...
Medical Xpress / Why zebrafish hearts heal so well: Early immune signals can improve repair even further
When the human heart is damaged by a heart attack, stiff scar tissue eventually forms around the affected areas. This weakens the heart's pumping ability and increases the risk of heart failure and arrhythmias. Zebrafish, ...
Phys.org / Satellite captures a sea of spinning clouds
Over the Southern Ocean surrounding Antarctica, winds can whip around the globe relatively unimpeded by land. Intrepid sailors termed these southern latitudes the Roaring Forties, Furious Fifties, and Screaming Sixties on ...
Phys.org / Aircraft measurements reveal surprisingly strong Southern Ocean biological productivity
The biological productivity of the Southern Ocean in the summertime is substantially greater than many previous estimates have suggested, according to new airborne research by the U.S. National Science Foundation National ...
Tech Xplore / AI training method helps robots carry lab-learned skills into real-world tasks
Robots are trained for specific tasks, such as cutting, using simulation. However, collecting real-world data is expensive, slow, and sometimes unsafe, particularly for tasks involving physical interaction. A new AI-based ...
Phys.org / Portable sensor detects PFAS in water on-site, cutting need for costly lab tests
A new study has unveiled a new method to cost-effectively and practically test for "forever chemicals" in water, potentially revolutionizing environmental PFAS monitoring. Led by Griffith University, the novel PFAS detection ...
Phys.org / Locked in stone for 210 million years, this newly identified crocodile cousin was built to crush larger prey
On a fateful day 210 million years ago, two crocodile cousins about the size of jackals stood side-by-side amid the low ferns of a humid riverbank that would one day become northern New Mexico. One of the crocs, Hesperosuchus ...
Medical Xpress / How a deadly hantavirus outbreak unfolded on a cruise ship for weeks before it was identified
A deadly outbreak of the rare hantavirus unfolded over the course of weeks on a cruise ship that sailed from Argentina toward Antarctica and then across the Atlantic Ocean, stopping at or near remote islands on the way as ...
Phys.org / AI matches human teachers: Brief pre-lecture chat boosts students' brain synchrony and learning outcomes
Millions of students worldwide have long relied on self-paced learning through pre-recorded video lectures, a model that forms the backbone of massive open online courses (MOOCs) and large-scale online education. Since the ...
Phys.org / Troubled waters: Jakarta battles deadly, invasive suckerfish
Mounds of slimy carcasses pile up on a riverbank in Jakarta where authorities are fighting an uphill battle against a fast-breeding invasive fish flourishing in Java island's heavily polluted waterways.
