As antibiotic resistance increases the search for new anti-bacterial treatments becomes more and more important. One way to design anti-bacterials is to find specific biochemical pathways that the bacteria require to survive, and develop drugs that block off these pathways.
In her fascinating and wide-ranging talk on multi-dimensional spaces and human consciousness, Tauba Auerbach briefly mentioned the fact that after an organism dies its molecules will gradually change "handedness" — from an entropy defying left-handed favoritism back to 50-50 over many thousands of years.
Urea is a small molecule formed as proteins are broken down. It’s excreted in urine, but isn’t particularly toxic at low levels so it’s found in cells throughout the body.
While I’m getting used to my new arrival the iGEM Team from Copenhagen have kindly provided a great guest post about their work over the summer.
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 [...]
