Phys.org / Sourdough starters: How flour choice shapes microbial communities
Sourdough starter, a fermented mix of flour and water, is a staple for bakers. It's also a rich experimental testing ground for microbiologists. The bread's chewy texture and tangy taste arise from the mix of microbes that ...
Phys.org / Mitochondria migrate toward the cell membrane in response to high glucose levels, study shows
Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move remain unclear. Research published in the Biophysical Journal shows that when beta cells—the ...
Medical Xpress / Scientists unravel neural networks that guide guilt and shame-driven behaviors
Feelings of guilt and shame can lead us to behave in a variety of different ways, including trying to make amends or save face, cooperating more with others or avoiding people altogether. Now, researchers have shed light ...
Phys.org / Team shatters 3D nanofabrication limits with meta-optics
Lawrence Livermore National Laboratory (LLNL) engineers and scientists, in collaboration with Stanford University, have demonstrated a breakthrough 3D nanofabrication approach that transforms two-photon lithography (TPL) ...
Medical Xpress / NU-9 halts Alzheimer's disease in animal model before symptoms begin
An experimental drug developed at Northwestern University has demonstrated further promise as an early intervention for Alzheimer's disease.
Medical Xpress / FDA may reduce how often supplement warnings appear on labels
The U.S. Food and Drug Administration (FDA) is weighing a change that could make warning labels on dietary supplements appear less often on packaging.
Tech Xplore / What the hyperproduction of AI slop is doing to science
Over the past three years, generative artificial intelligence (AI) has had a profound impact on society. AI's impact on human writing, in particular, has been enormous.
Phys.org / Super strain-resistant superconductors: Study narrows down the hidden symmetry
Superconductors are materials that can conduct electricity with zero resistance, usually only at very low temperatures. Most superconductors behave according to well-established rules, but strontium ruthenate, Sr₂RuO₄, ...
Tech Xplore / Model predicts optimal cooling and aging for stronger, lightweight aluminum alloys
High-strength aluminum alloys are critical for making cars and planes more lightweight and fuel-efficient, but manufacturers struggle to process them consistently.
Phys.org / Nature's pest controllers: Wasps keep whiteflies in check as resistance proves costly for survivors
Using insects such as wasps to control agricultural pests remains a resilient method, despite increasing resistance, a new University of Stirling study has shown.
Phys.org / Continuous spread: Raccoon roundworm detected in nine European countries
While the spread of raccoons in Europe is often discussed, their companion tends to remain unnoticed: The raccoon roundworm Baylisascaris procyonis arrived in Europe at the beginning of the 20th century with the first raccoons ...
Phys.org / Catch the Ursid meteor shower as it peaks just before Christmas
The last major meteor shower of the year, known as the Ursids, peaks soon, bringing glowing streaks to nighttime and early morning skies. Compared to other meteor showers, it's more subdued, but experts say it's still worth ...
