Speeding up reactions: biological vs. chemical catalysts

Most chemical reactions go pretty slowly at room temperature. This is good news most of the time, otherwise random parts of the environment would be exploding at regular intervals, but bad news for industrial processes which need reactions to occur.

Shooting the messenger: small RNA as a target for antibiotics

Shooting the messenger: small RNA as a target for antibiotics

All living cells contain DNA; the code for producing every protein needed by the cell. As DNA is important it needs to be kept safe. Plants and animals keep their DNA tightly twisted and organised inside a double-membrane bound nucleus while bacteria keep their DNA coiled up in a big circle, with the occasional loop [...]
