Phys.org / Four decades of data give unique insight into the sun's inner life
Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their findings in Monthly Notices ...
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 / 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 / Life forms can planet hop on asteroid debris—and survive
Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily ...
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.
Medical Xpress / Time changes still frustrate Americans, and the fall shift appears to linger longer
Individuals have a more negative reaction to the societal time change to Standard Time (ST) in the fall than to Daylight Saving Time (DST) in the spring, according to a study published in the open-access journal PLOS One. ...
Phys.org / HETDEX data reveal a vast 'sea of light' between early galaxies
Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the largest, most accurate 3D map yet of the light emitted by excited hydrogen in the early universe, 9 billion ...
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 / 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 ...
Phys.org / NASA finds source of Artemis II problem that forced rollback from the launch pad
NASA announced it had found the source of a helium flow blockage that forced it to roll the Artemis II rocket back from the launch pad at Kennedy Space Center and delay its lunar fly-by mission until at least April.
Phys.org / Paternal mitochondria in plants can rescue defective maternal DNA, study reveals
In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the mechanisms behind this ...
Phys.org / Ancient zircon crystals provide a window into early Earth history
There are many open questions about how our planet formed 4.55 billion years ago: When did plate tectonics start? When did the Earth's mantle begin to vigorously circulate in a process called convection? What was Earth like ...
