Phys.org / Three days of Ontario wildfire smoke brought unhealthy air to 106 million person-days
Smoke from Canada's July wildfires exposed people across Canada and the United States to unhealthy, very unhealthy or hazardous air for nearly 106 million person-days between July 15–17. Over the peak impact period of July ...
Phys.org / 'Imposing ignorance': US climate science under siege
A benchmark U.S. report on the fast-changing state of the Arctic has been canceled. The nation's top research body has removed a chapter on global warming from a reference manual for judges.
Medical Xpress / Food decisions in anorexia engage brain region tied to inflexible habits, study finds
Individuals with anorexia nervosa restrict food intake, sometimes to the point of starvation. Yet a new study published in The Journal of Neuroscience finds that the cognitive machinery they use to make decisions about what ...
Phys.org / Using salt to drive drug-carrying particles deeper into difficult-to-treat biofilms
Biofilms—bacterial communities encased in a sticky, polymer-rich matrix—can be difficult to treat because that matrix slows antibiotics and drug-carrying particles. With help from salt, though, Yale researchers have found ...
Phys.org / X-ray analysis reveals the inner life of leaves while advancing engineering efforts to reduce 'crop sweat'
In the Midwestern summer, humans and plants have to breathe through the heat and humidity. Researchers hope that a retooled crop plant—one with an improved ventilation system within its leaves—could thrive while avoiding ...
Medical Xpress / Air pollution-linked blood changes detected years before lung cancer diagnosis
A new study, published Tuesday in Nature Communications, found measurable changes in people's blood associated with exposure to air pollution and the subsequent development of lung cancer. The findings provide promising clues ...
Phys.org / Slow spin could explain why planets become hellish
Hundreds of Venus-like planets could soon help determine why some worlds become sweltering greenhouse hellscapes while others remain capable of supporting life. But before answering that question, scientists first need to ...
Phys.org / Real-time measurements reveal antiferromagnetic skyrmions move in line with an applied current
Skyrmions—essentially magnetic vortices—represent a promising approach in spintronics; in the future, they could serve as components in storage media or computers, potentially complementing established CMOS technologies. ...
Phys.org / Fungal chitin offers new route to tougher hydrogels for medical devices and soft robots
Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) and the University of Tennessee (UT), Knoxville, have made an advance by using a natural substance from fungi called chitin to create hydrogels ...
Medical Xpress / How precision nutrition may enhance effectiveness of GLP-1 drugs
A review titled "Integrating Precision Nutrition with GLP-1 Receptor Agonist Therapy: Mechanisms, Clinical Outcomes, and Pharmacoeconomic Implications" examines the biological mechanisms of nutrition, body composition, gut ...
Medical Xpress / 3D lifespan map suggests mouse ovaries keep a constant share of eggs primed
As mice age, their total egg reserve collapses around tenfold. Yet, according to a new study published in Nature Aging, the proportion of eggs in the brief window where a follicle is shifting from dormant to growing stays ...
Tech Xplore / Recycling discarded solar panels could yield $1 trillion by 2060, analysis finds
The world's rapid shift to solar power is creating a massive new waste problem, with up to 402 million tonnes (443 million tons) of discarded solar panels projected to accumulate globally by 2060, according to new research ...
