Phys.org / Bee bandits: How a yeast influences nectar-robbing behavior in bumble bees
From fundamental biological units as tiny as genes to complex societies, ecological systems rely on cooperation. All manner of organisms can benefit from working together to survive in a dog-eat-dog world. "Mutualism is a ...
Phys.org / Exposure to burn injuries played key role in shaping human evolution, study suggests
Humans' exposure to high temperature burn injuries may have played an important role in our evolutionary development, shaping how our bodies heal, fight infection, and sometimes fail under extreme injury, according to new ...
Phys.org / When blackouts occur during heat waves, Austin homes pose major risk
If the power goes out during a heat wave, there's nowhere more dangerous to be than where people spend most of their time—indoors. A new study led by researchers at The University of Texas at Austin is the first to assess ...
Medical Xpress / Intermittent fasting cuts Crohn's disease activity by 40% and halves inflammation in randomized clinical trial
A randomized controlled study found that time-restricted feeding—a form of intermittent fasting—significantly reduced symptomatic disease activity and systematic inflammation in adults with Crohn's disease and overweight ...
Tech Xplore / Hair-thin silica fiber microphone detects ultrasound from 40 kHz to 1.6 MHz
Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound frequencies beyond the reach of the human ear. Able to withstand temperatures up to 1,000°C, the ...
Medical Xpress / Speed-focused brain training tied to 25% lower dementia risk after 20 years
A simple brain-training exercise could reduce people's risk of developing dementia by 25%, a study said Monday, but with outside researchers expressing caution in interpreting the results.
