Bacteria made to mimic cells, form communities

Rice University scientists have found a way to engineer a new kind of cell differentiation in bacteria, inspired by a naturally occurring process in stem cells.

Genome-edited bull passes on hornless trait to calves

For the past two years, researchers at the University of California, Davis, have been studying six offspring of a dairy bull, genome-edited to prevent it from growing horns. This technology has been proposed as an alternative ...

Scientists uncover mystery of DNA methylation

All species mark their DNA with methyl groups. This is done to regulate gene expression, distinguish indigenous DNA from foreign DNA, or to mark old DNA strands during replication. Methylation is carried out by certain enzymes ...

Revolutionising the CRISPR method

Everyone's talking about CRISPR-Cas. This biotechnological method offers a relatively quick and easy way to manipulate single genes in cells, meaning they can be precisely deleted, replaced or modified. Furthermore, in recent ...

Using tiny organisms to unlock big environmental mysteries

When you hear about the biological processes that influence climate and the environment, such as carbon fixation or nitrogen recycling, it's easy to think of them as abstract and incomprehensibly large-scale phenomena. Yet ...

New strategy may curtail spread of antibiotic resistance

Spotless surfaces in hospitals can hide bacteria that rarely cause problems for healthy people but pose a serious threat to people with weakened immune systems. Acinetobacter baumannii causes life-threatening lung and bloodstream ...

Genomic study of 412 anthrax strains provides new virulence clues

By analyzing genomic sequences from more than 400 strains of the bacterium that causes anthrax, researchers have provided the first evidence that the severity – technically known as virulence – of specific strains may ...
