Phys.org / Ancient dust points to retreat of West Antarctic Ice Sheet during last warm period
Antarctica's Ross Ice Shelf and the West Antarctic Ice Sheet may have been far smaller during one of Earth's most recent warm periods, according to a new study that traced the origin of ancient dust preserved in Antarctic ...
Phys.org / Discovery of furtivovirus advances understanding of giant virus evolution
In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. This model suggests that every living organism can be traced back to a distant common ancestor. However, ...
Phys.org / ATLAS observes new Bc meson excited state
Protons and neutrons—the building blocks of matter—belong to a huge class of particles called hadrons. Hadrons are composite particles made of quarks that are bound together by the strong force. They are classified into two ...
Phys.org / Data-driven model captures dynamics of turbulence at scale
Whether the dust borne on the violent winds of a tornado or the sugar grains in a swirled cup of coffee, the behavior of particles carried along in turbulence is subject to some similarities—all of them difficult to predict ...
Phys.org / Single-step 8-9x expansion reveals nanoscale centrioles without electron microscopy
In a study published in ACS Nano, researchers from National Taiwan University report a new expansion microscopy strategy termed high-fold homogeneous expansion microscopy (hiHomoExM), capable of achieving approximately 8–9× ...
Phys.org / Rattlesnakes among most vulnerable to fungal disease and parasitic lung infection
Snakes are threatened with extinction in many places around the globe. Disease, often caused by parasites or fungi, is thought to be one of the key factors alongside habitat destruction. Prominent among fungal diseases is ...
Phys.org / Dog daycare leptospirosis outbreak in Los Angeles reveals broader public health risks
A 2021 outbreak of leptospirosis that sickened more than 200 dogs in Los Angeles County reveals critical gaps in vaccination practices and raises broader concerns about the spread of the disease between animals and people, ...
Phys.org / Imaginary-time technique speeds X-ray scattering simulations by 50-fold for extreme matter
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a new procedure, enabling them to speed up elaborate computer simulations that analyze matter under extreme conditions. In particular, this work ...
Phys.org / Heat stress linked to higher koala hospitalizations and deaths above 27 C
New research from the University of Sydney has provided the first associative link between heat stress and koala mortality. Published in Biology Letters, the results highlight how even moderate temperature rises can increase ...
Phys.org / Low pH outside cells rewires transport network and displaces Golgi apparatus, study finds
A new study led by the Universidad Carlos III de Madrid (UC3M) describes the mechano-chemical mechanism by which the acidity of the cellular environment destabilizes microtubules, the "avenues" that organize internal cellular ...
Phys.org / Stretching and squeezing drive the timing of glacial meltwater release
As meltwater drains through and beneath a glacier, it can alter how the ice flows and whether it breaks apart. Meltwater can also cause feedback that leads to more ice loss. Understanding when and how glacial meltwater drains ...
Phys.org / It looks like rice's own defense, but this fungal trick turns a lifesaving response into a crop-killing weapon
For about half the global population, rice is the staple food. Yet every year, a fungal disease—rice blast—destroys harvests that could feed 60 million people. Researchers at the Karlsruhe Institute of Technology (KIT) have ...
