Phys.org / AI mapping reveals hidden stage of Arctic freeze with climate implications
As autumn gives way to winter across the Arctic, the ground doesn't immediately freeze solid. Instead, soils often linger near the freezing point for days or even weeks in a phase called the zero curtain. In a new NASA-led ...
Medical Xpress / New brain cell formation stalls in adults with depression, study shows
Findings from a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons suggest that the trickle of neurons created in the adult hippocampus could be instrumental in preventing depression. ...
Medical Xpress / Thrombectomy provides 1-year gains for patients with severe stroke
A one-year follow-up analysis of a landmark clinical trial suggests that patients with severe strokes experienced better long-term outcomes after undergoing endovascular thrombectomy compared with medical management alone, ...
Medical Xpress / Study suggests new antibody therapy for tick-borne disease
Crimean-Congo hemorrhagic fever virus (CCHFV) is a dangerous virus spread by ticks. It transmits Crimean-Congo hemorrhagic fever (CCHF), a serious disease that has been spreading into new regions worldwide. Capable of killing ...
Medical Xpress / Atlantic climate variability enables the prediction of leishmaniasis outbreaks in North Africa
Climate variability in the Atlantic Ocean can help predict cutaneous leishmaniasis outbreaks in North Africa several months in advance. This is the finding of a new study led by the Barcelona Institute for Global Health (ISGlobal), ...
Phys.org / Laser-cut aluminum foil could replace costly terahertz polarizers
When physicists at the ARC Centre for Transformative Meta-Optical Systems (TMOS) needed a key component for their terahertz experiments, they ran into a frustrating problem—they needed tiny optical devices, known as wire-grid ...
Phys.org / Borneo forest fires spike again: Why El Niño isn't the sole culprit
Forest and land fires across Indonesia have spiked once again. News and social media in the country are flooded with images of thick plumes of smoke from Kalimantan (or Borneo)—the world's third-largest island—that are choking ...
Phys.org / Floating wetlands slash wastewater greenhouse gas emissions, according to study
A world-first trial of floating wetland pods in wastewater lagoons shows they cut greenhouse gas emissions by more than a quarter, highlighting their potential as a nature-based solution for decarbonizing the water sector.
Phys.org / What Gen Z‑led uprisings across Asia reveal about the strengths and limitations of youth protest
Recent Gen Z-led uprisings have reshaped political narratives across Asia, raising a pointed question: Can street-level youth outrage be transformed into governing power and lasting institutional change? Or does it burn out ...
Phys.org / South Africa produces enough food, yet millions face hunger. Better cold storage could help change that
South Africa can produce enough food for its population, according to official statistics. But millions face hunger, partly because food is lost and wasted in the value chain. An estimated 10.3 million metric tons of food ...
Phys.org / The dynamic duo: 'Weaving' hierarchical DNA materials with two classes of biomolecular nanomachines
Biomolecular nanomachines, such as enzymes and molecular motors, are the workhorses behind the synthesis and organization of complex materials in life. Powered by chemical energy, they build, transport and organize biomolecules, ...
Phys.org / Shrews exhibit reversible size changes in their skulls and noses to get through the winter
Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
