Researchers discover the exit route for Vibrio bacteria from cells

As soon as the foodborne pathogen Vibrio parahaemolyticus infects a human intestinal cell, the bacteria are already planning their escape. After all, once it is in and multiplies, the bacterium must find a way out to infect new cells.

'Survival of the fittest': How meiotic drivers shape the evolution of gamete formation

It can be hard to dispute the common adage 'survival of the fittest'. After all, "most of the genes in the genome are there because they're doing something good," says Sarah Zanders, PhD, assistant investigator at the Stowers Institute for Medical Research

Extrachromosomal DNA with potential to cause cancer drives poor patient outcomes

The multiplication of genes located in extrachromosomal DNA that have the potential to cause cancer drives poor patient outcomes across many cancer types, according to a Nature Genetics study published Aug. 17, 2020 by a team of researchers including Professors Vineet Bafna and Dr.Paul Mischel of the University of California San Diego and Professor Roel Verhaak of Jackson Laboratories.

Adaptive parallel mutations are more common in Lake Baikal amphipods

A group of scientists from Skoltech and the Institute for Information Transmission Problems of RAS (IITP RAS) showed, using Lake Baikal amphipods as an example, that parallel evolution driven by adaptations can be detected at the whole-genome level.

Light impulses can be used to trigger electrical excitation in plants

Optogenetics denotes the manipulation of cellular processes by light-based biological techniques. An international research team led by the Würzburg plant scientists Rainer Hedrich, Georg Nagel and Dirk Becker has succeeded in applying this method to higher plants: Light impulses can now be used to trigger electrical excitation in plants.

Using genetic engineering to study evolutionary assimilation of foreign DNA in a new host

All life is subject to evolution in the form of mutations that change the DNA sequence of an organism's offspring, after which natural selection allows the 'fittest' mutants to survive and pass on their genes to future generations.
