Studying the hotbed of horizontal gene transfers

For over 200,000 years, humans and their gut microbiomes have coevolved into some of the most complex collections of living organisms on the planet. But as human lifestyles vary from the urban to rural, so do the bacterial ...

Harvey samples saddled with antibiotic-resistant genes

Rice University scientists have released the first results of extensive water sampling in Houston after the epic flooding caused by Hurricane Harvey. They found widespread contamination by E. coli, likely the result of overflow ...

Cross species transfer of genes has driven evolution

Far from just being the product of our parents, University of Adelaide scientists have shown that widespread transfer of genes between species has radically changed the genomes of today's mammals, and been an important driver ...

Road rules for gene transfer are written in DNA

A new discovery suggests that bacteria's ability to transfer genes, like those associated with antibiotic resistance, are governed by a previously unknown set of rules that are written in the DNA of the recipient.

Fungus senses gravity using gene borrowed from bacteria

The pin mold fungus Phycomyces blakesleeanus forms a dense forest of vertically growing fruiting bodies, but how does it know which way is "up"? New research publishing 24 April in the open access journal PLOS Biology, from ...

Bacterial 'gene swapping' sparks disease outbreaks

A new study by scientists at the University of Liverpool documents, for the first time, how the ability of bacteria to swap genetic material with each other can directly affect the emergence and spread of globally important ...
