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 / Tropical butterflies 'hedge bets' on reproduction as extreme seasons reshape Amazon life
New research from Queen Mary University of London shows how extreme seasonal patterns are causing rainforest butterflies to adapt their reproductive strategies at a rapid pace, with implications for species resilience under ...
Phys.org / Protein shape mapping could detect diseases before symptoms appear
A University of Mississippi professor and his team have developed a technology that may one day lead to the early diagnosis of juvenile diabetes and CTE caused by traumatic brain injuries. The technology allows researchers ...
Phys.org / Unsealing cells' 'black box' strategy to regulate gene activation
While scientists have known for more than two decades that all cells use a strategy called RNA interference to regulate gene expression, a new study is the first to describe how a specific protein manages the step-by-step ...
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 / 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 / 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 / Timing in early brain growth may explain why closely related mammals build strikingly different cortexes
The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains. However, the proportions of different ...
Phys.org / Ice may release more iron than climate models predict
Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in the Proceedings of the National Academy of Sciences demonstrates that ice actively speeds up the ...
Phys.org / Tiny on-chip circuit could power next-generation quantum and AI technologies
Researchers from Monash University have developed a breakthrough nanoscale circuit that can generate, direct, and read light-based information, all on a single chip.
Phys.org / DNA reveals hidden UV defense network that dissipates energy in femtoseconds
New details of how DNA protects itself from harmful ultraviolet (UV) radiation show a hidden network of ultrafast molecular reactions that help prevent damage before it can trigger mutations that might lead to cancer, according ...
Phys.org / Collective vibrations unlock fast ion flow in superionic crystals
In the race to develop safer, faster-charging solid-state batteries and more efficient thermoelectric conversion technologies, engineers and scientists have long faced a fundamental challenge: how to ensure ions move through ...
