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 / 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 / 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.
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 / 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 ...
Phys.org / Climate change is now warming the deepest parts of the Arctic Ocean
While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is ...
Medical Xpress / Redheads face impaired wound healing: MC1R dysregulation to blame, but a new treatment might help
Chronic wounds (CWs), like diabetic ulcers or pressure sores, are a major health care challenge, especially in the elderly. These wounds, marked by persistent inflammation, often lead to infection and poor patient outcomes. ...
Phys.org / Moss spores survive 9 months outside International Space Station
Mosses thrive in the most extreme environments on Earth, from the peaks of the Himalayas to the sands of Death Valley, the Antarctic tundra to the lava fields of active volcanoes. Inspired by moss's resilience, researchers ...
Phys.org / Researchers uncover the source of widespread 'forever chemical' contamination in North Carolina
An environmental chemistry laboratory at Duke University has solved a longstanding mystery of the origin of high levels of PFAS—so-called "forever chemicals"—contaminating water sources in the Piedmont region of North ...
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 / The Suez Rift—once deemed inactive—is still drifting, study reveals
The tectonic plates under Africa and Asia are slowly drifting apart, as the Gulf of Suez that separates these two land masses continues to widen at a rate of about 0.26–0.55 millimeters per year.
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 ...
