Bacteria can spread antibiotic resistance through soil

When most people think about bacterial antibiotic resistance, they think about it occurring in bacteria found in people or animals. But the environment surrounding us is a huge bacterial reservoir, and antibiotic resistance ...

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 ...

Researchers probe secrets of bacterial immune system

Scientists from New Zealand's University of Otago and the Netherlands are continuing to unlock the secrets of a surprisingly flexible bacterial immune system, called CRISPR-Cas.

Two-part system turns stem cells into whatever you want

Whether using embryonic or adult stem cells, coercing these master cells to convert to the desired target cell and reproduce flawlessly is difficult. Now an international team of researchers has a two-part system that can ...

Protein could put antibiotic-resistant bugs in handcuffs

Staph infections that become resistant to multiple antibiotics don't happen because the bacteria themselves adapt to the drugs, but because of a kind of genetic parasite they carry called a plasmid that helps its host survive ...
