Phys.org / Are climate models detecting monsoon changes a decade too early? 'Super-simulations' say yes

Changes in rainfall within global monsoon regions affect the livelihoods of billions. For years, climate models have suggested that the fingerprint of human-caused climate change on monsoons would become visible by a certain ...

Phys.org / Molecular map reveals Andes hantavirus entry protein at the nanoscale

Hantaviruses, transmitted from rodents to people, have a death rate approaching 40%. They're found around the world, and because there are no approved vaccines or treatments, they're among the pathogens of highest concern ...

Phys.org / Female Daubenton's bats share scarce feeding grounds at the edge of their range, study finds

At newly colonized high-elevation sites in the central Italian Apennines, female Daubenton's bats take turns using the same hunting spots instead of feeding side by side. A study published by a research team from the University ...

Phys.org / Political polarization can spur CO₂ emissions and stymie climate action

In recent years, studies and media reports have blamed growing partisan hostility in the U.S. for shattered marriages, broken families, ruined holiday dinners, and increased stress. New CU Boulder research suggests it may ...

Phys.org / Protein regulator of sugars and fats may work with an unexpected partner—itself

A protein that is a key modulator of fat, glucose and cholesterol levels in the body usually works in tandem with another protein, but new research shows it can also work with an unexpected partner—itself. A team of Penn ...

Phys.org / Older male humpbacks sire more calves as populations recover from whaling

New research from the University of St Andrews published in Current Biology has shown that the role of age in male humpback whale reproduction has changed as populations recover from centuries of exploitation. Whaling drove ...

Phys.org / Over 70% of global ecosystems remain unsampled for critical underground fungi

Underground, intricate networks of soil fungi underpin the functioning of terrestrial ecosystems. Yet despite their global importance, only 30% of global ecosystems have been sampled for these fungal partners. Arbuscular ...

Phys.org / Beam-spin asymmetry study puts proton models to the test

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as easy. It requires peeling ...
