Medical Xpress / Outdated mortality benchmarks risk missing early signs of famine and delay recognizing mass starvation

Recent global crises have exposed the limits of a universal mortality threshold for declaring famine—an approach that can obscure how famine actually unfolds across different populations. In a paper published in The Lancet, ...

Phys.org / Supercomputer simulations test turbulence theories at record 35 trillion grid points

Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence ...

Phys.org / New lithium-based green phosphors rival today's commercial LED standard

Research results from Innsbruck, Schwabmünchen, and Düsseldorf demonstrate how the most widely used green phosphors in commercial LEDs can be replaced by representatives of an entirely new class of compounds. Green luminescence, ...

Tech Xplore / Counter-drone technologies are evolving—but there's no surefire way to defend against drone attacks

When the Federal Aviation Administration closed the airport in El Paso, Texas, and the airspace around it on Feb. 10, 2026, the cause was, ironically, the nearby use of a technology that could be key to keeping airports and ...

Phys.org / Bison hunters abandoned long-used site 1,100 years ago to adapt to changing climate, Great Plains study finds

On the Great Plains of North America, bison were hunted for thousands of years before populations collapsed to near extinction due to overexploitation in the late 1800s. But long before then, bison hunters used various strategies ...

Phys.org / Mapping where local pollution and fishing suppress climate refugia for world's coral reefs

As ocean temperatures rise due to climate change, corals and other sensitive organisms survive where temperatures are less extreme. But a new study from researchers at Florida Tech, published this month in the journal Communications ...

Phys.org / mRNA fragments reveal a hidden process that protects cells from harmful mutations

Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells can ramp up the activity ...

Phys.org / Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve ...

Medical Xpress / Gut microbes bolster immunity in HIV patients, research reveals

The circumstances surrounding a study on a deadly virus could hardly have been more dramatic. One of its first authors was forced to flee his homeland when it became a war zone. More than 2,000 kilometers away, the laboratory ...

Phys.org / New perspectives on how physical instabilities drive embryonic development

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal kingdom, from insects to ...

Phys.org / Cell division spindles self-organize like active liquid crystals—a theory that holds up

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells. The spindle is the machinery behind that process: It latches onto chromosomes (where DNA is stored) ...

Phys.org / How AI is distorting online research, from polls to public policy

Artificial intelligence is increasingly able to simulate human behavior and answer online surveys and political polls, putting the reliability of survey-based research at risk. Consequences can be serious, not only for science ...
