Medical Xpress / Rural communities face serious obstacles in promoting physical activity
People in rural communities have long experienced disproportionate levels of chronic disease, driven in part by systemic barriers to physical activity. A new study from North Carolina State University highlights ways some ...
Phys.org / Solar wind stirs Mars' upper atmosphere, boosting ion loss to space
Our sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow. As a result, the solar ...
Medical Xpress / Researchers find simple habit to improve physical and mental health
University of Missouri researchers have identified a simple, effective way to improve quality of life. A new study found that maintaining a consistent daily routine can reduce physical pain and ease symptoms of depression, ...
Phys.org / Combined rattlesnake proteins prove 10 times more potent than current antivenom in lab tests
University of Maryland researchers discovered a new approach to treating venomous snakebites—using the same toxin-blocking proteins that snakes evolved to protect themselves. The team found that specific combinations of blood ...
Medical Xpress / Eye contact helps infants 'tune in' to speaker's brainwaves and learn language
Infants use eye contact with speakers to work out what to pay attention to and synchronize their brainwaves, helping them learn language, scientists in Cambridge and Singapore have shown.
Phys.org / How fitness, speed and position shape competition in expanding populations
A study published in the Journal of Statistical Mechanics: Theory and Experiment (JSTAT), inspired by the behavior of bacterial colonies observed in previous experiments, uses mathematical models to describe the expansion ...
Medical Xpress / Ancient mummy DNA provides scientific evidence that colonization brought smallpox to the Americas
Ancient mummy DNA recovered in Chile has yielded the firmest evidence yet that European colonization brought smallpox to the Americas.
Medical Xpress / Chromosome-protecting protein may help explain muscle repair and the rarity of muscle cancers
A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the ...
Tech Xplore / AI reduces sensory hallucinations, even at night or in smoke
Multimodal large language models (MLLMs), which process multiple types of sensory information, such as text, images and audio, at the same time, are rapidly expanding the range of applications for artificial intelligence ...
Phys.org / Ancient diamond preserves evidence of water-bearing mineral deep in Earth's mantle
A team of Brazilian researchers discovered the first direct evidence that goethite—the mineral responsible for the brown color of soils—can withstand extreme pressures and temperatures all the way to the planet's interior ...
Phys.org / Volcanic eruptions in Pacific Ring of Fire may have cooled Earth for centuries
For around 12,000 years, the Earth has been in the Holocene epoch, a warmer period following a glacial period. During this epoch, however, there have been around 22 abrupt cold phases, each lasting up to several centuries ...
Medical Xpress / Experimental treatment significantly slows progression of a fatal brain disease in women during clinical trial
Researchers at Tel Aviv University have presented new findings indicating that the experimental drug Davunetide may significantly slow the progression of progressive supranuclear palsy (PSP) in women, who exhibited a markedly ...
