Phys.org / Stress-reduction molecule has potential to treat aging and metabolic disorders
University of Queensland researchers say the discovery of a new stress reduction role for a naturally occurring molecule in the body could lead to new drugs and treatment for metabolic disorders and aging.
Phys.org / Molecular surgery: 'Deleting' a single atom from a molecule
Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This process, called skeletal editing, can dramatically speed up drug discovery or be applied for upcycling ...
Medical Xpress / How exercise-induced migration of mitochondria protects the brain against stroke
Physical rehabilitation and symptom management still remain the mainstay of treatment for stroke, as clot removal or dissolution is effective only within a narrow time frame after the stroke. After that, many patients are ...
Phys.org / Lifting magnetic fingerprints using scanning probe microscopy
A Czech and Spanish-led research team has demonstrated the ability to distinguish subtle differences between magnetic ground states using a new form of scanning probe microscopy.
Phys.org / New structural insights reveal how human respiratory chain complexes assemble
A new study shows how one of the cell's most important energy-producing machines is built. Researchers at Karolinska Institutet have mapped late steps in the formation of the human respirasome, a large protein assembly that ...
Phys.org / Space station crew credits ultrasound machine for handling in-orbit health crisis
The astronauts evacuated last week from the International Space Station say a portable ultrasound machine came in "super handy" during the medical crisis.
Phys.org / Meet the marten: An updated look at a rare, adorable carnivore
Oregon State University researchers have painted a clearer picture of the coastal marten, a secretive, ferret-sized forest carnivore renowned for its cuteness but nearly driven to extinction by human activity in the 20th ...
Phys.org / 'Supercooling' keeps salamanders from freezing in Canadian winters
On a frigid April day, Brock University Professor of Biological Sciences Glenn Tattersall, then-Ph.D. student Danilo Giacometti and wildlife researcher Patrick Moldowan ventured out into Ontario's Algonquin Provincial Park ...
Phys.org / Socio-environmental movements emerge as key global guardians of biodiversity amid rising violence
A new study published in the Proceedings of the National Academy of Sciences reveals that organized civil society and social mobilization are key, yet often unrecognized, agents of global biodiversity conservation. By analyzing ...
Phys.org / COVID-era trick could transform drug and chemical discovery
Laboratories turned to a smart workaround when COVID‑19 testing kits became scarce in 2020. They mixed samples from several patients and ran a single test. If the test came back negative, everyone in it was cleared at once. ...
Medical Xpress / Uncovering cancer's hidden oncRNA signatures: From discovery to liquid biopsy
After being described in 2018, researchers knew they had something interesting with T3p, a single small RNA found in breast cancer but absent from normal tissue. The molecule took the team on a six-year journey to systematically ...
Phys.org / Meta-study reveals mechanisms of animals' adaptations to cope with climate change
Climate change has a wide range of effects on wildlife. It affects seasonal migration, reproduction times, body size and mass, and disrupts ecological processes, thereby posing challenges for the populations of some species. ...
