Phys.org / Scientists may have discovered a new extinct form of life
Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or ...
Medical Xpress / Both reward and aversion learning require the brain molecule sulfatase 1
Researchers at University of Tsukuba and their collaborators have demonstrated that learning from both rewarding and aversive outcomes requires a common brain molecule, sulfatase 1 (Sulf1). This extracellular enzyme removes ...
Medical Xpress / Episodic and semantic memory retrievals involve the same areas of the brain, according to new work
A new study into how different parts of memory work in the brain has shown that the same brain areas are involved in retrieving different types of information, according to researchers from the School of Psychology at the ...
Phys.org / Mighty microscopic fibers are the key to cell division and life itself
Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around it called a spindle. The spindle extends its many fibers from the chromosomes ...
Medical Xpress / Deep-learning algorithms enhance mutation detection in cancer and RNA sequencing
Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have developed two innovative deep-learning algorithms, ClairS-TO and Clair3-RNA, that significantly advance genetic mutation detection in cancer ...
Phys.org / NASA's Artemis II crewed mission to the moon shows how US space strategy has changed since Apollo
When Apollo 13 looped around the moon in April 1970, more than 40 million people around the world watched the United States recover from a potential catastrophe. An oxygen tank explosion turned a planned landing into an urgent ...
Phys.org / Swimming in a shared medium makes particles synchronize without touching
Several years ago, scientists discovered that a single microscopic particle could rock back and forth on its own under a steady electric field. The result was curious, but lonely. Now, Northwestern University engineers have ...
Phys.org / Asteroid 2024 YR4 has a 4% chance of hitting the moon. Here's why that's a scientific goldmine
There's a bright side to every situation. In 2032, the moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%) ...
Phys.org / Climate change made Australian heat wave 5 times more likely
Human-induced climate change made the intense early January heat wave in Australia five times more likely, according to a new analysis by World Weather Attribution.
Phys.org / Tapping into risk in America's drinking water
When you turn on the tap, you can typically expect clean, safe water to flow out. But behind that simple action lies a complex system of pipes, pumps, governance, and financials that, for millions of Americans, is at risk ...
Phys.org / Sloshing liquefied natural gas in cargo tanks causes higher impact forces than expected
What happens if liquefied natural gas (LNG) hits the wall of the cargo tanks in a ship? New research from the team of physicist Devaraj van der Meer from the University of Twente, published in the Proceedings of the National ...
Phys.org / Sea levels are rising—but in Greenland, they will fall
Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper published in Nature Communications. "The Greenland coastline is going to experience quite ...
