New genetic engineering strategy makes human-made DNA invisible

Bacteria are everywhere. They live in the soil and water, on our skin and in our bodies. Some are pathogenic, meaning they cause disease or infection. To design effective treatments against pathogens, researchers need to ...

Gene activity in defenders depends on invading slavemaking ants

Temnothorax americanus is a slavemaking ant found in northeastern America. These tiny social insects neither rear their offspring nor search for food themselves. Instead, they raid nests of another ant species, Temnothorax ...

Screening technique uncovers five new plant activator compounds

A new high-throughput screening technique developed by researchers at the RIKEN Plant Science Center (PSC) has been used to uncover five novel immune-priming compounds in Arabidopsis plants. Discovery of the compounds, which ...

Poxviruses defeat antiviral defenses by duplicating a gene

Scientists have discovered that poxviruses, which are responsible for smallpox and other diseases, can adapt to defeat different host antiviral defenses by quickly and temporarily producing multiple copies of a gene that ...
