Phys.org / Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
Medical Xpress / BCG vaccine may rewire brain immunity, shift Alzheimer's markers over 12 months
New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine—which is delivered through the skin to prevent tuberculosis—may remodel the human brain's immune environment, ...
Phys.org / A WRAP for biology's greasiest problem
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
Medical Xpress / Intermittent fasting maintains long-term weight loss, regardless of meal timing, study shows
A team of scientists from the University of Granada (UGR), the Granada Institute for Biomedical Research (ibs.GRANADA), the Public University of Navarra and the Biomedical Research Networking Center (CIBER) has demonstrated ...
Medical Xpress / You can dream while you're awake. The boundary between wakefulness and sleep is a lot blurrier than you'd think
Tonight, as you close your eyes in bed, something strange will happen to you: Your mind will drift from an ordinary thought to a dream, but it will be impossible to say exactly when it happened. We tend to imagine that the ...
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 ...
Medical Xpress / Precision fMRI maps prefrontal cortex in individuals, revealing fine-scale structures
Much like camera settings—filters, flashes and focus—affect what we notice in a final photo, the way scientists measure something can affect how we interpret and understand it. This is especially true when imaging things ...
Phys.org / Giant exoplanet may hold a magnetic grip on its host star
Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.
Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / Primate evolution kept aging rates stable for 25 million years despite lifespan gaps
Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifespans.
Medical Xpress / We can't entirely blame COVID vaccine mandates for lower vaccination rates today. It's not that simple
Childhood vaccination rates have slumped globally. In several countries, people are more hesitant about getting vaccinated. Populist political actors promote distrust of government and scientific institutions. And the disinformation ...
