Phys.org / The G-value paradox: Why similar genes can lead to very different brains
Biologists have long puzzled over why organisms with similar numbers of protein-coding genes can differ so dramatically in nervous system complexity. New research points to a potential link between the expanding diversity ...
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 / Inland seas may face widespread heat waves by midcentury as warming accelerates
Under the lead of the Leibniz Institute for Baltic Sea Research Warnemünde (IOW), climate simulations were used to investigate how 19 inland seas, including the Baltic Sea, are responding to climate change. The researchers ...
Phys.org / How the Atlantic herring adapted to the brackish water of the Baltic Sea
When the Atlantic herring colonized the Baltic Sea thousands of years ago, it needed to adapt to the low salinity. Genes with a vital role in the functioning of sperm, eggs and embryos were crucial to this adaptation. A new ...
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 / 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 / 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 / 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 / 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 / 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 / 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 ...
