Phys.org / Fresh brew, harsh bite: Coffee's bitter edge finally comes into full molecular view
Have you ever wondered why freshly brewed coffee smells so delicious, but tastes bitter? New research from the University of North Carolina School of Medicine has revealed the molecular details responsible for the detection ...
Phys.org / Smarter search for fuel-cell catalysts uses machine learning
A computational method combining generative AI with atomistic simulations can identify promising platinum alloy catalyst structures for hydrogen fuel cells, report researchers from Science Tokyo. Their approach addresses ...
Phys.org / Seismic attenuation techniques reveal what lies beneath Taiwan
As seismic waves travel through Earth, they gradually lose energy, a process called attenuation. That energy loss doesn't happen uniformly—some features in the crust sap far more energy from seismic waves than others. Researchers ...
Phys.org / Wildfire smoke's hidden ozone threat may be adding thousands of US deaths each year
A study that assesses the effects of wildfires over two decades shows that wildfire smoke significantly raises ground-level ozone and contributes to excess deaths from wildfire smoke in the United States each year. The research, ...
Phys.org / The birds and the babies: Humans and zebra finches have a similar technique for learning to speak
We are all born completely helpless, with little of the knowledge and skills we will need to survive as adults. Even our ability to communicate is almost entirely learned from our parents or caregivers.
Phys.org / Hidden proton pathways emerge as ultrathin polymer film method splits interface signals
Understanding how protons move at the interface between polymers and electrode materials is essential for improving fuel cells and related energy devices. However, conventional impedance measurements under inert conditions ...
Phys.org / Why gradual environmental change can trigger sudden species collapse and fragmented populations
When species are subjected to changing environments, they can survive in their current location through genetic adaptation. However, this ability is not unlimited. In a study published in PNAS, biomathematician Jitka Polechová ...
Phys.org / An everyday sweetener offers a surprisingly powerful engine for transparent, stretchable electronics
Professor Kyungwho Choi's team of the School of Mechanical Engineering at Sungkyunkwan University, in collaboration with Professor Jinsoo Kim's team in the Department of Chemical Engineering at Kyung Hee University, have ...
Phys.org / Old plant populations offer new clues to climate resilience
When scientists think about how plants will respond to climate change, they often look north. As temperatures rise, many species are expected to shift their ranges toward cooler regions with a loss of populations in warmer ...
Phys.org / Looped polymers unlock stronger, faster molecular binding through entropy, model suggests
Entropy gets a bad rap. Typically associated with randomness and chaos, it can also correlate with freedom and diversity. Cornell researchers have found that, thanks to the latter qualities, entropy can help bind certain ...
Phys.org / Cut marks on 1.6 million-year-old bones reveal early humans moved prized meat
There is an old adage that goes, "you are what you eat," meaning that the food you consume helps build your body and fuel your mind. The same is true now as it ever was. When it comes to early humans, studying what they ate ...
Phys.org / Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the ...
