Phys.org / 100 million years ago, an 'evolutionary fuse' was lit in the deep ocean, sparking squid diversification

From color-changing skin to jet-propelled motion, squid and cuttlefish have long fascinated scientists. To understand the origins of their unique characteristics, many attempts have been made to define their evolutionary ...

Phys.org / 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 ...

Phys.org / 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 ...

Phys.org / 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 ...
