Fins, fingers and toes: A new take on repeating body parts and how they come to be
As biologists know, nature can take its sweet time explaining itself. Andrew Gillis, associate scientist at the Marine Biological Laboratory (MBL), has been investigating how the paired fins of fishes evolved for nearly 20 ...

Precision work prior to cell division: How enzymes optimize DNA structure
Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the DNA is wrapped around ...

Targeting the tiniest divide: Research reveals potential vulnerability in bacterial reproduction
A Université de Montréal study has found a previously unknown mechanism in bacterial reproduction that could be attacked by future antibiotics. Bacteria reproduce by dividing into two: they form a wall, or septum, between ...

Viruses 'eavesdrop' on each other—but it can backfire
University of Exeter scientists studied chemical communication by phages (viruses that infect bacteria). The phages assessed in the study have two choices when they enter a cell: lie dormant or kill the cell and release new ...
