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 ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 ...
