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 / 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 / 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 / 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 / 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 ...
Phys.org / Stardust trapped in Antarctic ice reveals tens of thousands of years of solar system's past
When you think of outer space, you're likely picturing stars, planets and moons. But much of space is filled with clouds of gas, plasma and stardust—known as interstellar clouds.
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 / Dual spacecraft capture both hemispheres of interstellar comet 3I/ATLAS at once
The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA's Jupiter Icy Moons Explorer (Juice) spacecraft and NASA's Europa Clipper made unique observations of interstellar comet 3I/ATLAS ...
Phys.org / Quantum geometry provides theoretical limits on measurable properties of solids
Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids through a lens of quantum geometry. Their results shed light both on the physics of solids and on quantum ...
Phys.org / Identity traits sharply narrow who becomes friends or marries, model reveals
Our personal identity is composed of many dimensions, such as age, gender, ethnic background, or socioeconomic status. A research team led by Fariba Karimi from the Institute of Human-Centered Computing at Graz University ...
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 ...
