Phys.org / High-resolution dataset tracks land productivity changes to combat degradation
An international research team has developed the world's first 30-meter resolution dataset to track changes in land productivity, a crucial tool for fighting global land degradation. Published in Scientific Data, this innovation ...
Phys.org / Secrets of superfluid: How dipolar interactions shape two-dimensional superfluid behavior
In a recent study, researchers made a significant observation of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a 2D dipolar gas of ultracold atoms. This work marks a milestone in understanding how 2D superfluids ...
Phys.org / Coastal management model plays the long game against the rising tides
To protect against rising sea levels in a warming world, coastal cities typically follow a standard playbook with various protective infrastructure options. For example, a seawall could be designed based on the latest climate ...
Phys.org / Phosphorylation enables tau protein to form reversible droplets, offering insights into early Alzheimer's
In a study published in the Journal of the American Chemical Society, scientists explore how a brain protein called tau changes its behavior when a small chemical group called a phosphate attaches to it—a process known ...
Phys.org / DNA organization offers clues for advancing stem cell therapy
Scientists at the University of California, Riverside, have discovered how adult stem cells retain their regenerative power. The researchers demonstrate in a paper published in the journal Genes & Development that these cells ...
Phys.org / Scientists discover new trigger mechanism for solar microflares
A study published in The Astrophysical Journal Letters reveals new insights into the triggering mechanisms of solar microflares and the self-similarity of solar flares. The research was led by Prof. Bi Yi from the Yunnan ...
Phys.org / A genetic basis of adaptive evolution: Complex chromosomal rearrangements drive color changes in stick insects
Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies on many mutations with ...
Phys.org / Scientists map fastest pathways for replenishing Central Valley groundwater
Depleted groundwater threatens communities, agriculture, and ecosystems in California's Central Valley, which produces much of the nation's fruit, vegetables, and nuts. But the same acres where farmers have long cultivated ...
Phys.org / Personality test for bees: Research reveals differences in honey bee defense behavior within same colony
Researchers from the Cluster of Excellence Collective Behavior at the University of Konstanz have discovered that honey bees from the same colony have different preferences in terms of defensive behavior. While some are still ...
Phys.org / Sugar-mimicking molecule central to virulence of a common crop disease, study finds
In plants, the space between cells is a key battleground during infection. To avoid recognition in this space, a strain of the bacterial tomato disease Pseudomonas syringae manipulates plants by producing a substance called ...
Phys.org / Scientists hack cell entry to supercharge cancer drugs
A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body. Scientists at Duke University School of Medicine, University of Texas Health Science Center at San ...
Phys.org / Simulations predict how pesticides may affect honeybee colonies
Honeybees are essential pollinators for agriculture and natural ecosystems. Stressors like climate change, habitat loss and pesticide exposure threaten their ability to forage for pollen, a critical resource for colony survival. ...
