Phys.org / Mating reveals cholesterol's hidden role in male fruit fly lifespan
Scientists have discovered that the optimal diet for male fruit flies may depend strongly on whether they are reproducing, challenging long-standing assumptions about nutrition and aging. Led by researchers from the University ...
Phys.org / Mountain lions have major ecological impact even in small preserves
Big cats have a big impact. A long-term study showed that when mountain lions began regular visits to a small suburban preserve about 45 miles (72 kilometers) south of San Francisco, they changed the behavior of many other ...
Tech Xplore / Ultrathin membranes could transform hydrocarbon processing by slashing energy use
A team of international researchers has developed a new class of ultrathin polymer membranes that can rapidly and selectively separate complex hydrocarbon mixtures, potentially transforming how crude oil is refined and refinery ...
Phys.org / Trace additive unlocks faster bioplastic biodegradation without losing transparency or strength
Compostable plastics could be part of a solution to the world's plastic waste problem. But currently these materials need industrial composting facilities to break down. In a step toward making a home-compostable plastic, ...
Medical Xpress / Link between genetics and BMI has become stronger since rise in obesity rates, study finds
People who carry genetic variations linked to obesity are more likely to be heavier now than individuals with the same variants who were born before the recent obesity epidemic. Liam Wright of University College London and ...
Tech Xplore / Stretchable self-powered sensor delivers stable signals even at 668% elongation
Wearable medical devices that monitor heart rate, respiration and joint movements for long periods without battery concerns, electronic skins that sense external stimuli like human skin, and soft robots made of flexible materials ...
Phys.org / Rice gene switch helps plants rebound from cold and use nitrogen more efficiently
Global climate change has increased the frequency of regional cold spells, causing substantial yield losses and even crop failure. Meanwhile, excessive nitrogen fertilizer use in agriculture has increased non-point-source ...
Phys.org / Heat waves increase wildfire risk—a new study explains how much, and it's not a small number
When heat waves hit the Western United States, the risk of wildfires quickly rises. The prolonged heat dries out vegetation, but that's only part of the cause—heat waves also play other roles in spreading wildfires.
Phys.org / Heatwave hits more than one in two people in France
More than half of France's population was dealing with scorching temperatures on Friday, according to AFP's calculations, with hundreds of schools adapting their timetables to keep students out of broiling classrooms.
Tech Xplore / Wearable glove turns data into heat and touch for more personal insights
University of Adelaide researchers have developed a wearable glove that uses heat, touch and physical objects to transform data into a sensory experience. The prototype, called ThermoPhy, was developed as part of a remote ...
Phys.org / Drug-free nanoparticles stop tumor growth by transmitting biological messages to immune cells
A research team from the Technion's Wolfson Faculty of Chemical Engineering has developed an original technology for treating cancer using nanoparticles that carry no drugs at all and has demonstrated its effectiveness against ...
Medical Xpress / Update to 89-year-old motor homunculus model shows brain's motor cortex isn't as neatly organized as previously thought
For almost a century, budding neuroscientists have been taught that the headband-like strip of brain tissue over our ears that controls our movements, called the motor cortex, contains an orderly map of our bodies. Brain ...
