Phys.org / Strange 500-million-year-old marine fossils reveal a feeding strategy that still shapes oceans today
More than 500 million years ago, during what is known as the Cambrian period, the seas and oceans on Earth were filled with a myriad of marine animals, many of which have now become extinct. This evolutionary burst in new ...
Phys.org / Recreating dying stars reveals hydrogen's key role in cosmic dust formation
Silicon carbide (SiC) dust is one of the most important ingredients in cosmic dust, the tiny particles floating throughout the cosmos that eventually give rise to new planets and stars. This compound of silicon and carbon ...
Phys.org / Mostly empty foam overturns assumptions of electron beam stopping
When physicists fire beams of fast electrons at materials, they often need to know exactly how much energy those electrons will lose as they travel through. Through new research published in Physical Review Letters, a team ...
Phys.org / Atomic bands in two transition metal dichalcogenides hint at long-theorized quantum state
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside ...
Phys.org / Rivalry with neighboring groups may be a key driver of male size in primates
In many primate species, males are much larger than their female counterparts, which is generally attributed to male competition for mates (sexual selection). But bigger bodies may not just be about alpha males defeating ...
Phys.org / These computer voices sound human enough to mislead, but one layer of speech still breaks the illusion
We are surrounded by computer-generated voices these days, from navigation systems and voice assistants to automated announcements. But how human do these voices actually sound? A recent study by the Max Planck Institute ...
Phys.org / The first domesticated horses: 6,000 years of a complex story
Horses were being ridden, worked, and traded long before anyone thought it possible. New research pushes back the accepted timeline of human use of horses by centuries, showing that humans used horses in organized ways as ...
Phys.org / Ancient iceberg scratches reveal reverse Great Lakes snowbelt
Buffalo's legendary snowfall totals are largely the result of one unlucky geographic reality: the city sits east of the Great Lakes instead of west. Anyone who has lived through a winter in Buffalo, Cleveland or any snowbelt ...
Phys.org / Rice plants observed trapping and killing fall armyworm caterpillars
Rice plants and Venus flytraps share something in common that was not scientifically documented until recently. Using a faint smell to lure caterpillars into a trap, rice plants killed early-stage fall armyworm larvae by ...
Phys.org / A twinkling pulsar reveals invisible structures in space
The twinkling stars in the night sky are not just beautiful to look at. Their flickering reveals something about the varying temperatures and densities in the layers of Earth's atmosphere, which refract the light as it travels ...
Dialog / Optical meta‑conveyors enable programmable nanomanipulation along arbitrary open paths
The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new ...
Phys.org / Bee magnetism appears far more widespread than expected across 120 species
As married research professors at the University of Tennessee, Knoxville, Dustin Gilbert and Anne Murray often discuss their work once they get home each night. Their fields of study rarely crossover. That changed six years ...
