Phys.org / Sprint or marathon? Aging muscle stem cells shift from rapid repair to long-term survival
Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher levels of a protein ...
Tech Xplore / A programmable, Lego-like material for robots emulates life's flexibility
Mechanical engineers at Duke University have demonstrated a proof-of-concept method for programming mechanical properties into solid Lego-like building blocks. By controlling the solidity of hundreds of individual cells in ...
Phys.org / With international law at a 'breaking point', a tiny country goes after Myanmar's junta on its own
Just four months ago, Timor-Leste formally became a member of the Association of Southeast Asian States (ASEAN). This week, the tiny country took an unprecedented step: its judicial authorities appointed a prosecutor to examine ...
Tech Xplore / Robotics build path from rural Kenya to world stage
Jeremiah Kithinji had never touched a computer before he finished high school. A decade later, he is teaching robotics, and even took a team of rural Kenyans to the World Robotics Olympiad in Singapore.
Phys.org / Unexpected climate feedback links Antarctic ice sheet with reduced carbon uptake
A study in Nature Geoscience reveals that changes in the West Antarctic Ice Sheet (WAIS) closely tracked marine algae growth in the Southern Ocean over previous glacial cycles, but not in the way scientists expected. The ...
Phys.org / Polarstern heads to the Weddell Sea to probe Antarctica's sharp sea ice drop
With the departure of the research vessel Polarstern from Punta Arenas (Chile) scheduled for this weekend, the "Summer Weddell Sea Outflow Study" (SWOS) international expedition will commence. Up to early April, a multidisciplinary ...
Tech Xplore / Neptunium study yields plutonium insights for space exploration
Researchers at the Department of Energy's Oak Ridge National Laboratory are breathing new life into the scientific understanding of neptunium, a unique, radioactive, metallic element—and a key precursor for production of ...
Medical Xpress / Scientists build a 'Rosetta Stone' to decode chronic pain neurons
Researchers from the Center for Addiction and Mental Health (CAMH) and the Institute of Neurophysiology at Uniklinik RWTH Aachen in Germany have deciphered the molecular signature of so-called sleeping nociceptors—a type ...
Phys.org / Machine learning accelerates plasma mirror design for high-power lasers
Plasma mirrors capable of withstanding the intensity of powerful lasers are being designed through an emerging machine learning framework. Researchers in Physics and Computer Science at the University of Strathclyde have ...
Phys.org / Ancient American pronghorns were built for speed
The fastest land animal in North America is the American pronghorn, and previously, researchers thought it evolved its speed because of pressure from the now-extinct American cheetah. But recently, that theory has come under ...
Medical Xpress / Quantifying the role of reducing obesity in preventing common conditions
Researchers have quantified the role of obesity in common long-term conditions, showing for the first time the effect of losing weight in preventing multiple diseases.
Medical Xpress / Two in five cancers worldwide are likely preventable, says new research
Nearly 40% of new cancer cases worldwide in 2022 may be associated with modifiable risk factors, according to an analysis of 36 cancer types from 185 countries. The findings suggest that reducing exposures such as tobacco ...
