Medical Xpress / Feeling stressed? These immune cells might be key to understanding why
There are many ways that the human body responds to stress, from the adrenaline rush of the "fight-or-flight" instinct to more subtle, complex changes that may not be immediately recognizable to us.
Phys.org / Starting point for a COVID drug is the 5000th protein structure decoded at BESSY II
Many proteins have a complex architecture that enables biological functions. Molecules can bind to specific sites on a protein and alter its function. A team at HZB has now investigated the Nsp1 protein, which plays a role ...
Phys.org / Landowner trust and experience influence feral hog management, researchers find
Trust in others and prior experience with feral hogs were significant factors in whether landowners would commit effort and dollars to controlling the destructive animals, two studies have found.
Phys.org / The sea is higher than we thought and millions more are at risk, study finds
Climate change's rising seas may threaten tens of millions more people than scientists and government planners originally thought because of mistaken research assumptions on how high coastal waters already are, a new study ...
Phys.org / Study finds water oversight failures at California dairies
A Stanford Law report reveals California's inadequate monitoring of dairies and feedlots, highlighting the need for stronger regulatory enforcement to protect groundwater quality and community health.
Phys.org / SWOT satellite takes stock of world's river water
In a first, a space mission led by NASA and France has tracked Earth's rivers swelling and shrinking from month to month over the course of a year and found significantly less of a swing than previous model-based estimates. ...
Phys.org / 70-year field study finds fertilizer imbalance can halve mycorrhizal fungi
Almost all plants live in close symbiosis with so-called mycorrhizal fungi—an important symbiosis for absorbing essential nutrients. In their new study, a team led by ecologist Christina Kaiser from the Center for Microbiology ...
Phys.org / Poking a nanostring: Scientists uncover energy cascades in tiny resonators
Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...
Medical Xpress / AAOS: GLP-1 receptor agonist use increases five-year risk for osteoporosis
Treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) for type 2 diabetes and obesity is independently associated with a significantly increased five-year risk for osteoporosis, gout, and osteomalacia compared ...
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, ...
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 / NASA rules out asteroid smashup on the moon in 2032
Here's one less thing to worry about—or to look forward to: NASA has ruled out any chance that an asteroid called 2024 YR4 will hit the moon in 2032. Last year, the uncertainty surrounding the space rock's orbital path ...
