Regulating the ribosomal RNA production line

The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria Escherichia coli needs to slow ...

Researchers reveal why heat stress damages sperm

University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat.

Structural biology reveals new target to neutralize COVID-19

An international team of researchers have discovered a new and highly conserved site on the SARS-CoV-2 virus that can be neutralized by a specific antibody. Previous studies have reported that antibodies that block the virus ...

Researchers study DNA polymerases at the molecular level

Complex biological systems can be described as a network of chemical processes that take place in molecules. The scientists of the "ChemLife" research initiative at the University of Konstanz are working together in an equally ...

How bacteria turbocharged their motors

Using detailed 3-D images, researchers have shown how bacteria have evolved molecular motors of different powers to optimize their swimming.
