Phys.org / Tiny ancient fish fossil with preserved brain offers clues to early fish evolution
Over 300 million years ago, a minnow-sized fish died and fell to the bottom of a prehistoric swamp near the village of Trawden, Lancashire, in northwest England. The remains of this tiny fish—known as Trawdenia planti—became ...
Phys.org / Newly discovered corn trait may help improve crop drought tolerance
Researchers report some corn plants are genetically predisposed to develop longer, less constricted water-conducting tissues and deeper roots, which helps them deal with drought. That's the conclusion of a team led by Penn ...
Phys.org / Hidden toll: Interpersonal violence drives most of the world's annual cost of up to US $34 trillion
The media is full of news of war, terrorism and armed conflict, and this shapes our perceptions of violence. However, if we look at the costs resulting from these forms of violence, the numbers are surprising: About 12% of ...
Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Phys.org / Nautilus array to track missing exoplanet atmospheres
Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can't be directly imaged yet, so astronomers must get creative in how they search ...
Medical Xpress / Billions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A sweeping global review led by researchers at the University of British Columbia has found that mRNA vaccines—now administered billions of times worldwide—are safe and highly effective at preventing infectious diseases like ...
Phys.org / Lost megalodon vertebrae resurface, confirming 80-foot size estimate
An associated set of gigantic vertebrae belonging to the iconic extinct megalodon, or megatooth shark, that had been missing in action since the 1980s was discovered, providing new information about the shark's lifestyle. ...
Medical Xpress / Could creatine help depression? What five clinical trials show so far
Could the same supplement many people take to build muscle also help treat depression?
Tech Xplore / Physical pressure could make EV batteries last twice as long and reduce environmental impact
The key to making longer-lasting electric vehicle batteries may not be specialized materials or new chemistry, but simple physical pressure, according to new research.
Phys.org / A new CRASH clock measures the chance of satellite collisions, and it's ticking down fast
Imagine a piece of space debris the size of a hockey puck slams into a Starlink satellite at about 10 kilometers per second. The kinetic energy is equivalent to 2 kilograms of TNT, or a fully loaded semitruck traveling at ...
Medical Xpress / Discovery could help prevent cancer drug resistance before it starts
Cancer cells are quick to develop resistance to anti-tumor drugs. New research by scientists from the University of California, Davis, shows how cancers adapt to evade a class of anti-tumor drugs called BET inhibitors and ...
Phys.org / Extreme droughts in the rainforest reduce important feedback between soil and atmosphere, study finds
Isoprene is a volatile organic compound (VOC) that is produced naturally by plants. More than 500 megatonnes of isoprene are emitted each year into Earth's atmosphere, primarily from tropical forests. Soils are recognized ...
