Phys.org / Detailed map reveals groundwater levels across the U.S.
How much fresh water is in the United States? It's a tough question, since most of the water is underground, accessible at varying depths. In previous decades, it's been answered indirectly from data on rainfall and evaporation. ...
Phys.org / Honeycomb lattice sweetens quantum materials development
Researchers at the Department of Energy's Oak Ridge National Laboratory are pioneering the design and synthesis of quantum materials, which are central to discovery science involving synergies with quantum computation. These ...
Phys.org / Microbubbles can release microplastics into our water
Microbubbles in the tap water you just poured into a plastic glass are strong enough to create tiny abrasions on the inner layer of the plastic—quietly adding to our growing microplastic problem.
Phys.org / Revealing the cell's nanocourier at work
An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls constitutive exocytosis: the uninterrupted delivery of spherical molecular packages to the cell surface. This ...
Phys.org / Spaceflight causes astronauts' brains to shift, stretch and compress in microgravity
Spaceflight takes a physical toll on astronauts, causing muscles to atrophy, bones to thin and bodily fluids to shift. According to a new study published in the journal PNAS, we can now add another major change to that list. ...
Phys.org / Early humans relied on simple stone tools for 300,000 years in a changing east African landscape
Our prehistoric human ancestors relied on deliberately modified and sharpened stone tools as early as 3.3 million years ago. The selection of rock type depended on how easily the material could be flaked to the desired shape ...
Phys.org / Sharks are famous for fearsome teeth, but ocean acidification could make them weaker
Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.
Phys.org / Nationwide racial bias shapes media reporting on gun violence, study suggests
Mass shootings in white-majority neighborhoods received roughly twice the news coverage of mass shootings in neighborhoods where a majority of residents were people of color, while coverage of police-involved shootings was ...
Phys.org / X-ray four-wave mixing captures elusive electron interactions inside atoms and molecules
Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, opens a new way to see ...
Phys.org / T. rex grew up slowly: New study reveals 'king of dinosaurs' kept growing until age 40
For decades, scientists have been counting annual growth rings—similar to tree rings—inside fossilized leg bones of Tyrannosaurus rex to estimate how old the giant carnivores were when they died and how quickly they grew ...
Phys.org / German study examines why women are less likely to hold leadership positions in logistics
The logistics industry is one of Germany's key economic sectors—yet women remain significantly underrepresented in its leadership ranks. To explore the reasons behind this imbalance, Prof. Dr. Fridtjof Langenhan and Prof. ...
Medical Xpress / 1 in 5 people say losing their pet was worse than losing a person
For one in five people, losing a pet has been more distressing than losing a human loved one. New research has revealed that 21% of those who experienced both types of bereavement found their pet's death harder to bear.
