Phys.org / Ice Age erosion may explain Appalachians' smoother northern peaks
Hike north on the Appalachian Trail and the scenery slowly transforms. Rugged, steep ridgelines in Tennessee and Virginia soften into the broad summits and smooth peaks of Pennsylvania and New Jersey. According to new research ...
Phys.org / Shorter early-life telomere length could predict survival in Arctic seabirds
A study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family). In the work titled "Who's coming home? ...
Phys.org / Marine plastic pollution alters octopus predator-prey encounters, study shows
More than 350,000 chemicals are used worldwide, and many find their way into the ocean through plastic pollution. As plastics accumulate in coastal waters, they continuously leach bioactive additives that can interfere with ...
Phys.org / Decision-making nudges can improve racial equity in tenure decisions
After years of research, teaching, and service, a faculty member's tenure and future in academia hinge on the evaluations of their peers—senior faculty who serve on promotion and tenure committees. These evaluations can ...
Phys.org / Nutrient-driven 'death fronts' may explain why some antibiotics fail outside the lab
Antibiotics are medical marvels that have transformed once deadly bacterial infections into manageable conditions. But with a rise in antibiotic resistance that renders existing treatments ineffective, new agents are urgently ...
Phys.org / How studying yeast in the gut could lead to new, better drugs
A new study sheds light on the behavior of yeast cells in the gut, paving the way for new lines of yeast that more efficiently produce therapeutic drugs tailored to address specific diseases. The research is published in ...
Phys.org / AI provides a more precise time of death post-mortem
Artificial intelligence can be used to provide a more precise time of death, which could be crucial in murder investigations. The method was developed by researchers at Linköping University and the Swedish National Board ...
Phys.org / Americans reveal deepening split between self and country
American reports of individual well-being have remained relatively stable over decades, but confidence in the nation has sharply declined. James N. Druckman and colleagues analyzed long-term survey data from two projects: ...
Phys.org / Methane's missing emissions: The underestimated impact of small sources
Methane is a potent greenhouse gas, with an impact estimated at 80 times that of CO₂. Although efforts are being made to reduce the contribution of big polluters to methane in Japan, new research from Osaka Metropolitan ...
Phys.org / With the flip of a switch, scientists harness light to program how particles interact and assemble
NYU scientists are using light to precisely control how tiny particles organize themselves into crystals. Their research, published in Chem, provides a simple and reversible method for forming crystals that can be used to ...
Phys.org / Finding the honey bee dance floor: New method shows how it moves within the hive
When honey bees find a good source of food, they return to their hive and perform a waggle dance. It consists of a series of movements that communicate the direction and distance to nectar, pollen or water relative to the ...
Phys.org / 40,000-year-old Stone Age symbols may have paved the way for writing, long before Mesopotamia
Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new analysis by linguist Christian Bentz at Saarland University and archaeologist Ewa Dutkiewicz at the Museum ...
