Science X / Tropical cooling points to a world 5.4°C colder at the Ice Age peak
During the Last Glacial Maximum, tropical regions with lush vegetation would have looked completely different. The last Ice Age reached its peak about 20,000–21,000 years ago, and massive ice sheets covered parts of North ...
Medical Xpress / High-speed microscopy reveals electrical activity across the brain
Within the brain, neurons compute by generating electrical impulses. These signals travel throughout neurons, which are in turn connected in vast networks that control brain functions such as sensory perception, memory formation ...
Tech Xplore / Helmholtz resonance powers miniature boats and ultrasonic flying robots
When air is blown across the neck of a bottle, it doesn't just produce a pleasant tone: it also demonstrates a phenomenon called Helmholtz resonance. This occurs when airflow passing across an opening causes air trapped inside ...
Phys.org / Phytophthora dieback linked to habitat loss and lower digging activity among quendas in Western Australia
A new study from Murdoch University has found that the introduced plant disease Phytophthora dieback is indirectly hindering quendas in Western Australia's jarrah forests by reducing their habitat quality and consequently ...
Phys.org / Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island
Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species. However, ...
Medical Xpress / Evolution of wastewater and environmental surveillance in carceral settings traced
Wastewater and environmental surveillance (WES)—the analysis of water and environmental samples like sewage to enable early, noninvasive tracking of biological and chemical markers across a population—is a powerful and increasingly ...
Medical Xpress / Youth-associated protein helps restore healthy function in immune cells in the aging brain
Researchers at the Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells.
Phys.org / Early settlement dynamics in the Pacific revealed through ancient DNA
New genetic analyses of ancient human skeletons from western Remote Oceania are shedding light on the complex history of settlement in this vast Pacific region over the past 3,000 years. With island nations such as Vanuatu, ...
Phys.org / Nonrepeating photonic crystal may enable more tunable, reliable semiconductor lasers
Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are ...
Phys.org / The Nigerian fishing community being eaten up by the Atlantic
The beach shrinks every year in Ayetoro, in southern Nigeria, and what is left is peppered with the remains of homes swallowed by the ocean—some years ago, some just months prior.
Medical Xpress / Mental health and peer support: Sometimes online communities can help
The mental health impact of social media—particularly online peer support groups—is unclear. "The scientific literature is contradictory," said Université de Montréal psychology professor Diana Cárdenas. "Some studies have ...
Medical Xpress / Autistic people often struggle to tell when they're too hot: 5 ways to help
Recent decades have seen a year-on-year increase in clinical diagnoses of autism. Unfortunately, autism and temperature regulation problems often go hand in hand, especially in summer.
