Phys.org / Chiral skyrmion flows enable new approach to nanoscale logic devices
In magnetic materials with antisymmetric exchange interactions, novel particle-like spin textures called magnetic skyrmions can appear and be manipulated by electrons. First observed in 2009, they have been created and controlled ...
Medical Xpress / New clues to why some women experience recurrent miscarriage
Researchers at the Victor Chang Cardiac Research Institute, University of Sydney, and the Royal Hospital for Women have uncovered important new insights into the biology of recurrent miscarriage—a devastating condition ...
Medical Xpress / Bone-targeted estrogen delivery reverses postmenopausal osteoporosis without uterine side effects in mice
Postmenopausal osteoporosis is a condition that weakens bones, making them brittle and prone to fracture. Taking the hormone estradiol can reverse these effects, but it may also increase endometrial and uterine cancer risks. ...
Medical Xpress / Study sheds light on cellular resistance to osimertinib in adenocarcinoma
Some lung cancers manage to overcome a targeted drug therapy despite it showing initial success. Yale researchers have now discovered a molecular-level resistance mechanism that begins to take hold as early as six to eight ...
Medical Xpress / Reduced opioid use found after knee surgery with mini-scope technique
A new study led by Marshall University researchers found that patients who underwent knee surgery using a minimally invasive "needle arthroscopy" technique used significantly fewer opioids after surgery compared to those ...
Medical Xpress / Even low-intensity smoking increases risk of heart attack and death, study finds
An analysis of data from almost two dozen long-term studies finds that even low-intensity smokers have a substantially higher risk of heart disease and death compared to people who never smoked, even years after they quit. ...
Phys.org / Hunting for 'wandering' black holes in dwarf galaxies
Tracking down black holes at the center of dwarf galaxies has proven difficult. In part it is because they have a tendency to "wander" and are not located at the galaxy's center. There are plenty of galaxies that might contain ...
Tech Xplore / X-ray vision dives deep to boost safety, inspection and response
X-ray imaging is useful for seeing inside objects without causing damage, but until now it was not practical for use underwater. Oak Ridge National Laboratory researchers have developed the first X-ray imaging system that ...
Medical Xpress / Targeted protein degradation: A new way to combat harmful proteins in tumor cells
A new active substance attacks a key protein in tumor cells, leading to complete degradation. In cell experiments, this caused cancer cells to lose their protection and die. The active substance was developed by researchers ...
Medical Xpress / Muscle protein linked to exercise opens new way to treat Alzheimer's
Alzheimer's disease (AD) is a devastating cause of memory loss and cognitive decline, for which no curative treatment is available. Among lifestyle factors, physical activity stands out as possibly one of the strongest defenders ...
Phys.org / Beyond the habitable zone: Exoplanet atmospheres are next clue to finding life on planets orbiting distant stars
When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to its star, water on its ...
Phys.org / Behavioral patterns and shopping habits shape household food waste, study shows
A study by Associate Professor Nevin Cohen and colleagues reveals that food waste in U.S. households varies significantly based on behavioral patterns and shopping habits, rather than simple demographics like age or income ...
