Phys.org / Managing hydrogen emissions is key to maximizing climate benefits as hydrogen use expands, say researchers
Current estimates of hydrogen's climate impact are now sufficiently robust to inform policy and business decision-making, according to researchers in a new review article on the climate impacts of hydrogen emissions.
Phys.org / Cells have a built-in 'seatbelt' against sudden stress
When cells experience sudden physical stress, like stretching or pressure, they can activate a fast, protective mechanism that shields their nuclei from destruction, according to a new study published in the Biophysical Journal. ...
Medical Xpress / Engineered Salmonella deliver cancer-killing viruses, shrinking liver and pancreatic tumors in mice
Researchers at the University of Massachusetts Amherst have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors—two cancers with an extremely ...
Phys.org / Dead Sea archaea sport reinforced swimming tail for hypersalty waters
Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and temperatures ranging from 10–50°C, it takes unique environmental adaptations to survive in such harsh ...
Phys.org / Q&A: Why do telomeres shorten when a cell divides, and how does it affect human aging?
In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, but over time, the copying process degrades. After many cycles of making copies, the ends of the ...
Phys.org / Laser beam builds cell-like protein networks without chemical modification
Networks of protein fibers play important roles in living cells. To understand the dynamical behavior of these networks, model networks are needed to perform in vitro studies. However, fabrication of protein networks similar ...
Medical Xpress / Nursing home staffing declined in states that protected facilities from COVID-19 malpractice lawsuits, study finds
Nursing homes across the country had less staffing in states where legislatures granted the facilities immunity from COVID-19-related lawsuits filed by patients and their families, according to findings from a new UCLA-led ...
Medical Xpress / Copper imbalance tied to autism's social symptoms and white matter development
Trace elements are needed only in small amounts, but they can have large effects on the developing brain. A research team led by Niigata University has now reported that copper, an essential trace element, may help connect ...
Medical Xpress / Why insulin, the core element of diabetes treatment remains inaccessible for millions of people
The discovery of insulin in 1921 revolutionized diabetes care. Type 1 diabetes went from being a death sentence to a manageable chronic condition.
Phys.org / Climate vulnerable residents in Nigeria are creating makeshift adaptation systems
Residents in informal settlements in Lagos—who are among the most vulnerable to climate change—have developed sophisticated, multi-scale climate adaptation systems and are earning a living from climate action, a new study ...
Medical Xpress / Unexpected chromosome interaction fuels aggressive cancers, researchers discover
Published in Nature, researchers at the University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center report a previously unrecognized change in how the cell's genetic material is packaged into structures called ...
Phys.org / Animals were sharpening their senses long before the Cambrian explosion, ancient tracks reveal
Tracks left by some of the earliest complex animals are giving new insights into how they experienced the world. New research reveals how these creatures started to understand their surroundings, paving the way for animal ...
