Researchers from Tokyo Metropolitan University have identified how certain dangerous bacteria spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-producing E. coli (STEC), finding that single bacteria attach to a surface and elongate before
How can we predict the way a real material, such as a polymer, responds mechanically over timescales ranging from the ultrafast motion of atoms to the slow deformations measured in a laboratory? This is a deceptively difficult problem.
Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure is correspondingly complex: The outer cell membrane,
Access to clean water depends not only on preventing pollution but also on being able to detect contaminants quickly and reliably. Among the pollutants of concern are metal ions such as mercury, lead and zinc, which can enter aquatic environments through industrial and other
Researchers at Stanford Medicine have developed two new artificial intelligence models of the biological cell. The first, called universal cell embedding, paved the way for a second-generation model called TranscriptFormer, which has been trained on data from 112 million cells
Laboratory animals are anesthetized to avoid pain during invasive procedures. Anesthesia is necessary for these animals' welfare, but it is not always without problems: Substandard anesthesia can cause suffering, distort experimental results and force researchers to repeat
After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physical contacts through chromatin loops that act as bridges, bringing together sequences that are far
Explosive volcanic eruptions can be as destructive as they are difficult to predict, launching pyroclasts—the fragments of magma and rock blasted from a volcano—into the air and surrounding areas. These particles can have wide-ranging impacts, as seen during this summer's
When forests burn, the direct consequences are obvious: houses go up in flames and habitats are destroyed. The damage caused by smoke extending far beyond the fire area is less visible. Sarah Meier, an environmental economist at ETH Zurich, investigated this in relation to
A team of researchers has found that a common wastewater pollutant turned male fathead minnows into worse fathers and fiercer rivals, revealing ecological impacts that laboratory studies missed.
