With the ‘resolution revolution’ of recent years, it should in principle be possible to determine atomic resolution structures of any proteins using electron cryo-microscopy (cryo-EM). However, in practice, preparation of frozen samples that are suitable for high resolution imaging is a barrier to progress. Christopher Russo’s group in the LMB’s Structural Studies Division have now […]

Decoding how detection of odours leads to diverse behaviours in flies
We, and all animals, sense things in our surroundings and react to them, but how a sensory input reaching the brain is transformed into behaviour is still unknown for all but the most simple reflexes. To better understand this, Greg Jefferis’ group in the LMB’s Neurobiology Division in collaboration with researchers at the Janelia Research […]
A novel mode of RNA recognition based on structure not sequence
Our genetic code is translated from DNA into proteins through an intermediate molecule: messenger RNA (mRNA). One major way in which synthesis of proteins can be regulated is through turnover of mRNA; less protein is produced from a short-lived mRNA molecule. The signal for the degradation of a particular mRNA is the removal of a […]
Creating an entire bacterial genome with a compressed genetic code
Jason Chin’s group in the LMB’s PNAC Division have, for the first time, synthesised the entire genome of a commonly used model organism, the bacterium E. coli. There has only been one previous example of synthesis of an entire genome: for the Mycoplasma bacterial genome, which consists of approximately 1 million bases. Over the last 5 […]
How tighter ligand binding in drug target cell-surface receptors is achieved
Much of the communication in cells is dependent on the presence of cell-surface receptors that detect signals in the form of messenger molecules called ligands. One large family of receptors are G protein-coupled receptors (GPCRs). This family includes a number of important drug targets, so understanding their structure and function are important. Their name derives […]
How eating feeds into the body clock
We are regularly reminded that a balanced diet is key to staying healthy and preventing disease. What is less well known is that the time at which we eat may also be an essential to long-term health. Central to this are circadian rhythms – commonly referred to as ‘body clocks’. These are endogenous daily rhythms that […]
