Phys.org / Bacteria from bumblebees can produce vitamin B₂ in soya drinks
Researchers at DTU have developed a new method that can reduce the time needed to find new bacteria for fermentation. They have now identified a bacterium that can be used both for acidification and to increase the vitamin ...
Phys.org / Alzheimer's-linked protein tau plays a role in cell division
All processes such as wound healing, hair growth, and the replacement of old cells with new ones depend on cell division. During this process, chromosomes inside the cell must be evenly divided between two daughter cells. ...
Phys.org / SoCal's hybrid bees outsmart Varroa mites before they even hatch
Southern California is home to a flying black-and-yellow treasure. While commercial honeybee hives nationwide are collapsing under attack from deadly parasites, a unique hybrid bee found only in this part of the state has ...
Phys.org / Using menstrual blood-derived particles to treat osteoarthritis
New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers ...
Phys.org / Unlocking Earth's 4.5-billion-year secret: The case of the missing lead
Geoscientists have long relied on different forms of lead to understand Earth's geological history and how it was created over billions of years. However, there is a mystery that has been puzzling scientists for decades: ...
Phys.org / Glaciers rapidly declining, with extreme losses in 2025
Earth's glaciers are continuing to shrink at alarming rates, with new international research revealing that 2025 was among the worst years on record for global ice loss. Published in the Climate Chronicles collection of Nature ...
Phys.org / Tarantulas may use learning and memory to search for food and locate their retreats
Researchers have documented several cases of spatial orientation in tarantulas living both in trees and in underground burrows. Spatial orientation refers to the ability of an animal to understand where it is in three-dimensional ...
Phys.org / Seabirds reveal global mercury distribution in oceans
Mercury released into the oceans affects marine environments worldwide. Traditionally, its distribution and quantity have been estimated using marine biogeochemical simulation models.
Phys.org / After reaching speeds of 10,657 meters per second, Artemis II hurtles home for make-or-break splashdown
The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data and took in unprecedented moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday's splashdown.
Phys.org / Could your housemates be changing your gut bacteria? An island bird study suggests so
Living with friends may quietly be altering your gut bacteria, according to a new study from the University of East Anglia. Research on a colony of tiny island birds reveals they share more of their gut bacteria with the ...
Phys.org / Medieval Japanese poetry and buried trees help elucidate volatile space weather
On Earth, extreme solar activity often appears as beautiful, benign auroras. But venturing beyond the safety of the Earth's magnetic field, one faces the full brunt of a temperamental star that can suddenly erupt with flares ...
Phys.org / AI-designed proteins built from scratch can recognize specific compounds
Professor Gyu Rie Lee of the Department of Biological Sciences successfully designed artificial proteins that selectively recognize specific compounds using AI through joint research with Professor David Baker. The research, ...
