Making a meal of DNA in the seafloor

While best known as the code for genetic information, DNA is also a nutrient for specialized microbes. An international team of researchers led by Kenneth Wasmund and Alexander Loy from the University of Vienna has discovered ...

Move over CRISPR, the retrons are coming

While the CRISPR-Cas9 gene editing system has become the poster child for innovation in synthetic biology, it has some major limitations. CRISPR-Cas9 can be programmed to find and cut specific pieces of DNA, but editing the ...

Study shows how some bacteria withstand antibiotic onslaught

In a study with implications for chronic infections, Princeton researchers have described multiple pathways that some bacteria use to tolerate normally lethal antibiotic treatments. The findings overturn common assumptions ...

What lives inside the chicken gut?

In a recently published study, investigators from Norwich and Surrey have more than doubled the number of microbial species known to live in the chicken gut. As the health and wealth of humans is tied to the health and productivity ...

A bacterial toxin that acts as a mediator rather than a killer

Traditionally, bacterial toxins have been seen as killers of target cells. But is there more than meets the eye? Umeå University Professor Teresa Frisan and her team have discovered that toxin-host interactions are more ...

Where antibiotic resistance comes from

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started ...

Safer CRISPR gene editing with fewer off-target hits

The CRISPR system is a powerful tool for the targeted editing of genomes, with significant therapeutic potential, but runs the risk of inappropriately editing "off-target" sites. However, a new study publishing July 9, 2020 ...
