Phys.org / Cells use a little-known molecule to protect themselves from iron overload
Iron is essential. Our cells need it to produce energy, carry oxygen throughout the body and power countless chemical reactions that sustain life. But this metal has a dark side. When too much of it is left free inside cells, ...
Phys.org / EU cities plan to compensate for a fifth of their emissions through carbon removal, but few have thought through how
An analysis of 103 European cities' climate-neutral plans for 2030 (including 22 capital cities) shows that municipalities are planning to rely on carbon removal to compensate for about a fifth of their emissions. This would ...
Phys.org / Constipation is common in astronauts—blood tests provide new answers
For astronauts in space, constipation is a well-known problem. But why this happens has long been unclear. Now, a new study from the University of Copenhagen in collaboration with NASA provides an idea of what happens in ...
Phys.org / US could exhaust domestic phosphorus within 40 years, but waste offers reserves
The United States could exhaust its domestic phosphorus supply within 40 years. Europe, Latin America and Southeast Asia already depend on imports from China and Morocco to meet their needs. Without phosphorus, crops cannot ...
Phys.org / Stable RNA elements open new possibilities for mRNA therapeutics
A research team led by Director Kim V. Narry at the Center for RNA Research within the Institute for Basic Science (IBS) has discovered compact viral RNA elements that can make mRNA more stable and increase protein production. ...
Phys.org / New AI model detects hidden signs of solar eruptions hours before they emerge
Long before dark sunspots appear on the sun's surface, a new active region—where powerful solar eruptions can originate—begins showing subtle signs of its formation. Now, researchers say a new artificial intelligence model ...
Phys.org / Long-lost convent rediscovered under a soccer field in Denmark
A medieval monastery complex, long believed to be lost, has now been identified using ground-penetrating radar (GPR) in Roskilde, Denmark. The investigations have uncovered extensive and well-preserved remains of the St Clare's ...
Phys.org / Tiny DNA rotor lets microscopes track gene transcription one base pair at a time
Scientists often describe life as a series of chemical reactions. Pallav Kosuri, Ph.D., describes life as movement. Chemical reactions are how you drive the movement of atoms, proteins, cells and bodies—without movement, ...
Phys.org / Doomscrolling at work wastes time, but the real cost is what happens after
Whether on lunch break or on the clock, many employees scroll through the news and social media during the workday. Researchers found that employees who "doomscroll" at work suffer hidden costs that extend beyond lost productivity.
Phys.org / Europe's mountain summits are warming—vegetation is responding in surprisingly different ways
Decades of climate change have not left Europe's mountain vegetation unscathed. However, the changes observed do not always match expectations. As a new international study by a research team led by researchers from the University ...
Phys.org / Butterfly-inspired technology could change the way we monitor air
Respiratory infectious diseases and air pollution remain persistent global health challenges. Yet the tools used to monitor airborne threats are often expensive, power-hungry and difficult to deploy outside laboratories.
Phys.org / Cells pulse together as they grow—and malignant cells pulse the longest
Epithelial cells are the tiny shields that line and protect our bodies. In a developing embryo, epithelial cells grow, divide and move into positions to form the outer layers of our skin and the surfaces of our organs and ...
