New tool to assess largely ignored risk in pharmaceutical industry
A new method to test the likelihood of a drug turning into a potentially harmful version of itself when it enters the body has been developed by researchers at Cardiff University. In collaboration with Liverpool John Moores University and AstraZeneca, the team have developed a simple approach to trawl through large databases of pharmaceutical drugs and assess the likely risk of a drug undergoing racemisation - a process in which a drug flips into a mirror image of itself and becomes either inert or potentially dangerous.

Even wild mammals have regional dialects
Researchers from Cardiff University's Otter Project have discovered that genetically distinct populations of wild otters from across the UK have their own regional odours for communicating vital information to each other. The findings could have implications for wild mammal conservation efforts. The study, which profiled chemical secretions from the Eurasian otter, suggests that genetically distinct populations of wild mammals have different odour dialects, which may have been driven by geographical separation.

Complications at birth associated with lasting chemical changes in the brain
New King's College London research, published today in eLife , shows that adults born prematurely - who also suffered small brain injuries around the time of birth - have lower levels of dopamine in the brain. This chemical change has been linked to lack of motivation and enjoyment in normal life, and changes to attention and concentration, which could all be early signs of more serious mental health issues such as substance dependence and depression.

Fatty molecule in human blood controls malaria parasites' decision to leap to mosquitoes
Fatty molecule in human blood controls malaria parasites’ decision to leap to mosquitoes
Depletion of a fatty molecule in human blood propels malaria parasites to stop replicating and causing illness in people and instead to jump ship to mosquitoes to continue the transmission cycle, according to a new study by an international research team co-led by the University of Glasgow. The discovery, published online in Cell, answers a longstanding question about what controls this critical step in the life cycle of Plasmodium falciparum , the parasite responsible for about half a million malaria deaths worldwide each year.

Dealing with disaster - when rooted to the spot
When nature turns nasty plants can't run for cover, they have had to evolve to survive what the environment throws at them. Whether that's drought, flooding, saline soils or extreme temperatures, scientists, led by a team at the University of Nottingham , have now discovered that flowering plants have adopted a single biochemical mechanism to sense multiple environmental stresses, that enhances survival.

Formation of porous crystals observed for the first time
Scientists at the University of Bristol have, for the first time, observed the formation of a crystal gel with particle-level resolution, allowing them to study the conditions by which these new materials form. The study showed that the mechanism of crystal growth follows the same strategies by which ice crystals grow in clouds, an analogy which could improve our understanding of these fundamental processes In addition, this novel mechanism allowed the research team to spontaneously form sponge-like nanoporous crystals in a continuous process.
