Biotechnologists have constructed a genetic regulatory circuit from human components that monitors blood-fat levels. In response to excessive levels, it produces a messenger substance that signalizes satiety to the body. Tests on obese mice reveal that this helps them to lose weight.

Viruses are as simple as they are 'smart': too elementary to be able to reproduce by themselves, they exploit the reproductive machinery of cells, by inserting pieces of their own DNA so that it is transcribed by the host cell. To do this, they first have to inject their own genetic material into the cells they infect. Researchers have studied how this occurs and how long it takes for this process to be completed.

Scientists have glimpsed key chemical events, known as redox reactions, inside living cells of fast-growing Synechococcus. The work marks the first time that redox activity, a very fast regulatory network involved in all major aspects of a cell's operation, has been observed in specific proteins within living cells. The findings hone scientists' control over a common tool in the biofuels toolbox - a microbe that supplies some of the oxygen you breathe.

Like automobiles, ribosomes must pass through 'quality control' after their many components are assembled. Scientists investigated an important component in this control process. The researchers demonstrated that a specific protein, which occurs in all cells from yeast to humans, works like a molecular control switch and prevents incomplete ribosomes from leaving the 'assembly hall'.
