Medical Xpress / One wrong mouse swap exposes how social learning shapes future choices
Humans and other animals can learn new skills and behaviors from others they interact with. This process, referred to as social learning, has been widely investigated in the past, particularly in the context of responses ...
Medical Xpress / Major surgery may accelerate memory loss in 1 in 7 older adults
Going through surgery can take a significant toll on a patient's physical health and capabilities, especially if they are elderly. A recent study found that the effects extend far beyond mobility and pain management, as the ...
Tech Xplore / AI model predicts building fire spread, redirecting evacuees to safer exits in real time
A fire alarm jolts you from your office desk, and you head for the nearest exit. But what if the closest exit has already been blocked by the fire? Researchers at the National Institute of Standards and Technology (NIST) ...
Medical Xpress / Prenatal Zika exposure may trigger vision, hearing and social changes despite seemingly healthy births
Infants exposed to the Zika virus during pregnancy may face hidden developmental challenges, even if they appear healthy at birth. A recent study at the University of Wisconsin-Madison highlights the need for better developmental ...
Medical Xpress / Brain circuit that times a state of low metabolism could have implications for space travel
You have gone without food for days, and the temperature drops to near freezing. What do you do? For some animals, the answer is influenced by the brain's circadian clock. Hummingbirds, bats, and mice are among the animals ...
Medical Xpress / Long-hidden 'junk DNA' regions may help explain cancer-linked genome instability
Many repetitive regions of the genome have been considered "junk DNA" because the available technologies did not allow them to be studied at sufficient resolution. This is the case for the SST1/NBL2 macrosatellites, considered ...
Phys.org / Global mangrove forests rebound, offering hopeful sign for climate and coastal resilience
Mangrove forests, once considered one of the world's most threatened coastal ecosystems, are showing signs of recovery worldwide, according to new research from Tulane University that finds decades of losses largely offset ...
Phys.org / Wildfires reverse decade of ozone cleanup in the United States, study reveals
Ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air, according to a new study titled "Fires reverse progress toward ...
Phys.org / Mathematician solves origami donut efficiency challenge with fewest folds
Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper. Yet, no one could quite figure it out until recently.
Medical Xpress / Favorable lifestyle and health linked to lower dementia risk even in people with a genetic risk factor
With dementia cases expected to nearly triple worldwide by 2050, researchers are increasingly focused on identifying ways to prevent or delay the disease. While lifestyle and health-related factors, such as blood pressure ...
Phys.org / Teaching AI to design optical surfaces using real-world imperfections
Designing surfaces that precisely control how light behaves at the nanoscale is tricky. Optical Fourier surfaces, which are nanostructured gratings that redistribute light into specific directions and wavelengths, hold enormous ...
Phys.org / Why jellyfish can't rise to the surface
Using box jellyfish as an example, researchers from Kiel University show how the physics of density, not behavior or physiology, can prevent animals from reaching the surface even as they actively swim upward.
