Medical Xpress / GLP-1 medications get at the heart of addiction, study finds
Researchers at Washington University School of Medicine in St. Louis have shown in a new study that GLP-1 medications may be effective at treating and preventing substance-use disorders across all major addictive substances ...
Phys.org / Simulation makes it possible to study movements of cell's largest protein complexes without supercomputers
Large protein machines in the body carry out many of the cell's most essential tasks, from energy production to the regulation of signal transmission. Although they can now be imaged in great detail using cryo-electron microscopy, ...
Medical Xpress / Better sleep could reduce anxiety in later life
As humans grow older, their emotional stability and sleep patterns can change significantly. For instance, some past studies have found that many older adults find it harder to manage negative emotions, experience higher ...
Phys.org / Influenza's molecular theft caught in action—how the virus steals the cap of host RNA in order to replicate
The cold season is in full swing, throats are scratchy and noses are running. We feel ill and hope it is not the flu. The influenza virus continues to pose a threat to our health. It triggers seasonal epidemics and, from ...
Phys.org / A new face for 'Little Foot,' the most complete Australopithecus skeleton to date
What did the face of our ancestors look like three million years ago? Our international team has answered this question by virtually reconstructing the facial fragments of Little Foot, the most complete Australopithecus skeleton ...
Phys.org / Antibacterial coatings with short-term effect may fail over longer periods of time
Researchers from the Institute of Physics and the Institute of Molecular and Cell Biology of the University of Tartu have shown in a recently published study that antibacterial coatings which initially appear highly effective ...
Phys.org / Drinking water at risk long after wildfires, study warns
Canada's drinking water can remain at risk long after wildfires burn out, according to a UBC-led global review that found water-quality impacts often emerge months or years later—not just immediately after a fire. Researchers ...
Medical Xpress / Functional photoacoustic microscopy reaches super-resolution by tracking red blood cells
The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires. While modern imaging technologies allow researchers to follow the activity ...
Phys.org / Just three molecules can launch gene-silencing condensates in stem cells
A new study has uncovered how an exceptionally scarce protein can orchestrate the assembly of large-scale gene-silencing structures inside cells, and what happens when that process breaks down. The findings, published today ...
Medical Xpress / Study finds 45% of adults 65 and older improved over 12 years
Aging in later life is often portrayed as a steady slide toward physical and cognitive decline. But a new study by scientists at Yale University suggests an alternate narrative—that older individuals can and do improve ...
Tech Xplore / How hawks slip through tight gaps: A flight stability trick drones could copy
Birds have an ability to fly through obstacles by shifting their shape in flight, which is difficult to reproduce in uncrewed aerial vehicles, commonly known as UAVs or drones. A new study from researchers at the University ...
Phys.org / What's going on inside quantum computers? New method simplifies process tomography
Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum computers can solve complex equations at staggeringly fast speeds that vastly outpace regular computers. ...
