Phys.org / An unprecedented Antarctic heat wave hit in the dead of winter—what it signals for the decades ahead
In the middle of the Antarctic winter, during months of darkness when temperatures often dip below −30°C, the continent warmed dramatically. In July and August 2024, temperatures in parts of East Antarctica rose by up to ...
Medical Xpress / Experimental drug may restore movement after stroke
Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered ...
Phys.org / Blue carbon: Unearthing the ocean's own climate fix
It's a common misconception that rainforests are the lungs of Earth. Our oceans produce most of the oxygen we consume and are more effective at storing carbon.
Phys.org / Sewers have been hiding a climate problem in plain sight, and this new tool finally exposes its true scale
Methane is the second-largest greenhouse gas after carbon dioxide. According to the Climate and Clean Air Coalition, anthropogenic methane emissions account for nearly 45% of current net warming, making it an important factor ...
Phys.org / Beer and cannabis could share 'sex switch,' study finds
Researchers at University College Dublin have identified a genetic "switch" that determines the sex of cannabis plants, and found the same system may exist in hops. The study, published in New Phytologist, pinpoints a specific ...
Phys.org / How deceptive content reached millions of voters during the 2020 US elections
Over the past decades, the diffusion of fake news and other deceptive content on social media platforms has become a heated topic of debate. Some past studies have explored the broad impact of online misinformation, while ...
Phys.org / How giants that vanished 10,000 years ago triggered ripple effects that are still felt today
Between 50,000 and 10,000 years ago, many of the world's largest mammals disappeared. Picture creatures like saber-toothed cats with 7-inch fangs and elephant-sized sloths. Woolly mammoths whose curved tusks grew longer than ...
Phys.org / Molecular quantum nanosensors reveal temperature and radical signals inside living cells
Researchers at the National Institutes for Quantum Science and Technology (QST), Japan, and The University of Tokyo, Japan, in collaboration with Kyushu University, Japan, have developed a new class of biocompatible molecular ...
Phys.org / Single-vesicle profiling could push liquid biopsies toward everyday clinical use
Extracellular vesicles, or EVs, are tiny membrane-bound particles released by nearly all cells. They carry proteins, RNA, lipids, and other biological cargo that reflect the condition of their parent cells. Because EVs circulate ...
Phys.org / At just four nanometers thick, this metal starts behaving in a way physicists did not expect
Researchers in the University of Minnesota Twin Cities have discovered a powerful new way to control the electronic behavior of a metal—by manipulating the atomic properties of materials where they meet. The study, published ...
Medical Xpress / Vegan diet beats Mediterranean diet on emissions and metabolic health in randomized trial
A new randomized clinical trial provides some of the clearest evidence to date that what we eat can meaningfully reshape both human health and the health of the planet. Researchers have found that a low-fat vegan diet reduced ...
Phys.org / Hold your nose and don't stop for a selfie: Why getting up close to a beached whale is a really bad idea
The beaches of Sydney's Royal National Park have been disrupted by a pungent odor. And its source is drawing in more than just seagulls.
