Phys.org / Moss spores survive 9 months outside International Space Station
Mosses thrive in the most extreme environments on Earth, from the peaks of the Himalayas to the sands of Death Valley, the Antarctic tundra to the lava fields of active volcanoes. Inspired by moss's resilience, researchers ...
Dialog / Hydrogenases spill the beans: Key catalytic moves revealed
Hydrogenases catalyze the reversible splitting and production of hydrogen gas (H2), using complex catalytic cofactors comprising Earth-abundant nickel and/or iron ions. These enzymes, especially the [NiFe]-hydrogenases (fig. ...
Phys.org / Discovery of rare protist reveals previously unknown branch of eukaryotic tree of life
A research team from the Faculty of Science, Charles University in Prague has discovered Solarion arienae, an extremely rare and morphologically unique unicellular eukaryote that sheds new light on early eukaryotic evolution.
Medical Xpress / Not all immune cells are created equal: Memory T cells in tissues outlast those in blood
Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found throughout the body: some ...
Medical Xpress / Redheads face impaired wound healing: MC1R dysregulation to blame, but a new treatment might help
Chronic wounds (CWs), like diabetic ulcers or pressure sores, are a major health care challenge, especially in the elderly. These wounds, marked by persistent inflammation, often lead to infection and poor patient outcomes. ...
Phys.org / Why mysterious structures within Earth's mantle hold clues to life here
For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.
Phys.org / The paradox of climate protest
Climate activism takes many forms, but one of the most visible is so-called disruptive protests. These protests are characterized by interruptions to everyday life or specific cultural events. Examples of disruptive protests ...
Medical Xpress / AI-driven system automates fax filing and digital consent, saving 8,500 staff hours
An emerging artificial intelligence-powered system developed at Penn Medicine has tripled the speed of fax processing and cut a full week off the new patient intake process—freeing up thousands of staff hours. The system, ...
Phys.org / New substitution method enables high-precision nuclear reaction measurements using natural copper
A joint research team has made important progress in the field of photoneutron cross section measurement. The team proposed a substitution measurement method that avoids the use of expensive and hard-to-prepare high-purity ...
Medical Xpress / Most people are happy to do their own hearing tests at home. Could it relieve pressure on the NHS?
If the NHS recommended it, would people test their own hearing at home and use self-fitting hearing aids?
Phys.org / The Suez Rift—once deemed inactive—is still drifting, study reveals
The tectonic plates under Africa and Asia are slowly drifting apart, as the Gulf of Suez that separates these two land masses continues to widen at a rate of about 0.26–0.55 millimeters per year.
Phys.org / Tea leaf experiments suggest tropical forests may better withstand climate change
Researchers at Northern Arizona University and the Smithsonian found an unconventional method to understand how rainforests will survive with climate change—making tea with living leaves at the top of the rainforest canopy.
