How cells navigate in messy environments

Your cells need to get around. For example, immune cells must roam around your body to locate sites of infection, and neurons must migrate to specific positions in the brain during development. But cells do not have eyes ...

Physical mechanisms explaining DNA and RNA twist changes

The double-helix structure of DNA is deformed by environmental stimuli, which will then affect gene expression, and eventually trigger a sequence of cellular processes. Recent research led by a physicist from City University ...

New method simultaneously measures flow and oxygen

An international research team headed by the Max Planck Institute for Marine Microbiology in Bremen, Aarhus University and the Science for Life Lab in Uppsala has developed tiny particles that measure the oxygen concentration ...

Discovery uncovers need for ammonia emission regulations

A discovery by former Carnegie Mellon Ph.D. student, Mingyi Wang, leading a large collaborative team, sheds light on one way new particles are forming in the upper troposphere. The study, published in Nature, reveals an unexpected ...
