Why macrophages rest in healthy tissue

ETH scientists have shown that the immune system's macrophages are regulated not only biochemically, but mechanically as well. This could explain why the cells are less active in healthy body tissue.

Bending DNA costs less energy than assumed

The way DNA folds largely determines which genes are read out. John van Noort and his group have quantified how easily rolled-up DNA parts stack. This costs less energy than previously assumed. Publication in Biophysical ...

RNA microchips

Ribonucleic acid (RNA) is, along with DNA and protein, one of the three primary biological macromolecules and was probably the first to arise in early life forms. In the "RNA world" hypothesis, RNA is able to support life ...

Alcohols as carbon radical precursors

Alcohols play a pivotal role in organic synthesis because they are ubiquitous and can be used in a variety of well-established transformations. However, in C-C bond formation reactions, despite being central to organic synthesis, ...

Remedy against superbacteria found in crowberry

Researchers in Oulu have found small fragments of an antibacterial protein, also known as peptides, in a microbe living in crowberry. The peptide is able to destroy bacteria that cause infections. Based on the peptide, a ...

Physicists explain how large spherical viruses form

A virus, the simplest physical object in biology, consists of a protein shell called the capsid, which protects its nucleic acid genome—RNA or DNA.  The capsid can be cylindrical or conical in shape, but more commonly ...
