Medical Xpress / Brain circuit controlling compulsive behavior mapped
Researchers at Karolinska Institutet in Sweden have identified a brain circuit that can drive repetitive and compulsive behaviors in mice, even when natural rewards such as food or social contact are available. The study ...
Phys.org / Biodegradable mulching film can protect plants without pesticides or plastics
Whether you're a home gardener or an industrial farmer, you might be familiar with mulching films—plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these ...
Phys.org / New membrane sets record for separating hydrogen from CO₂
When designing membranes that separate industrial gases, scientists often incorporate structures that attract the gas they want to obtain. This attraction can enhance the membrane's permeability, and help isolate the desired ...
Medical Xpress / Current heart attack screening tools fail to identify half the people who are at risk, study shows
Current cardiac screening tools used to prevent heart attacks fail to identify nearly half of the people who are actually at risk of having one, according to a new study led by Mount Sinai researchers.
Phys.org / Laser-induced break-up of C₆₀ fullerenes caught in real-time on X-ray camera
The understanding of complex many-body dynamics in laser-driven polyatomic molecules is crucial for any attempt to steer chemical reactions by means of intense light fields. Ultrashort and intense X-ray pulses from accelerator-based ...
Medical Xpress / Hidden immune cells linked to early type 1 diabetes detected in lymph nodes
Type 1 diabetes (T1D) impacts nearly two million Americans, and by the time most people learn they have it, most of the body's insulin-producing cells are destroyed. Now, pinpointing a hidden group of immune "attack" cells ...
Phys.org / Bright squeezed vacuum reveals hidden quantum effects in strong-field physics
In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.
Medical Xpress / A two-minute fix for procrastination
You know that assignment, message or email you keep avoiding—the one that lingers in the back of your mind even as you scroll, tidy or "just check one more thing"? New research from UC Santa Barbara offers a science-backed ...
Phys.org / Mercury pollution in marine mammals is increasing, new study finds
In 2017, a new global treaty was meant to bring mercury pollution under control. But three decades of data from UK harbor porpoises show mercury is still increasing, and is linked to a higher risk of dying from infectious ...
Medical Xpress / Cerebrospinal fluid motion in the brain captured in remarkable detail
Cerebrospinal fluid (CSF) is a clear and watery liquid that flows in and around the brain and spinal cord. Its functions include protecting parts of the nervous system, delivering nutrients and removing metabolic waste.
Phys.org / Male green hermit hummingbirds: Bills evolved for battle
Let's get one thing out of the way: All hummingbirds fight. Most species fight for food, using their tiny bodies and sharp bills to force competitors away from flowers. But the green hermit hummingbird, which lives primarily ...
Phys.org / Artificial cartilage mimics natural flexibility with adjustable structure
A Washington State University research team is working to create an artificial cartilage that is similar to natural cartilage with a recipe that can be corrected along the way.
