Phys.org / Spider venoms could stop deadly varroa mites killing honey bees
Spider venoms contain ingredients that could lead to a new treatment to protect honeybees from the deadly Varroa destructor mite, according to a study led by the University of the Sunshine Coast. Researchers identified components ...
Phys.org / How much do friends influence teens' mental health? What a new study can (and can't) tell us
During adolescence, young people become especially sensitive to peer influence—more so than at any other time in life. So how does this affect their mental health?
Phys.org / More colorful songbirds face higher extinction risk
In the humid jungle of Vietnam, Natalia Ocampo-Peñuela and Monte Neate-Clegg spent hours patiently waiting to spot the rare "Halloween bird." Officially known as the collared laughingthrush, this songbird has striking orange, ...
Phys.org / Swimming crab trapped in plastic bottle survives two months at sea
How did a large crab end up trapped inside a plastic bottle with an opening smaller than its body? Hiroshima University researchers investigated this unusual marine mystery, revealing a lesser-known impact of marine plastic ...
Phys.org / New biosensor reveals rare lipid gathers in membrane hotspots during cell stress
Inside every cell are lipid molecules that make up cellular membranes, helping organelles communicate and respond to stress. Researchers have struggled to observe lipids in action because current detection tools lack sufficient ...
Phys.org / Harsh UVB bursts leave tadpoles with more DNA damage than longer exposure
Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. ...
Phys.org / Quiet outings linked to more frequent dangerous wildlife encounters
The more people expand into previously natural areas, the more wildlife and humans step on each other's toes, leading to more interactions that may result in conflict. This includes national parks, where people flock to recuperate ...
Phys.org / Beyond the dust: Families describe daily health challenges near the Salton Sea
A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality and structural inequities combine to place children ...
Phys.org / TESS just found a planet in a new way—and more may be hiding in its eight years of data
For the first time, NASA's TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly ...
Phys.org / DNA-based nanoswitch can flip in milliseconds and stay in one state for days without continuous forcing
Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that past versions required ...
Phys.org / 400-year-old painting reveals a bat's secret diet
Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As ...
Phys.org / How a giant planet survived its star's death, then migrated inward
When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star's violent demise. Now, observations from NASA's James Webb Space Telescope (JWST) may finally explain the planet's ...
