Molecular biologists travel back in time 3 billion years

A research group working at Uppsala University has succeeded in studying 'translation factors' – important components of a cell's protein synthesis machinery—that are several billion years old. By studying these ancient ...

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 ...

New data on 'jumping genes' linked to cancer

Scientists from the University of Granada and GENYO have discovered a mechanism via which our cells protect themselves against these transposable or mobile genetic elements, known as "LINE-1," which are involved in the development ...

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.
