The secrets of a tadpole's tail and the implications for human healing
The secrets of a tadpole’s tail and the implications for human healing
It is generally appreciated that frogs and salamanders have remarkable regenerative capacities, in contrast to mammals, including humans. For example, if a tadpole loses its tail a new one will regenerate within a week. For several years Enrique Amaya and his team at The Healing Foundation Centre in the Faculty of Life Sciences have been trying to better understand the regeneration process, in the hope of eventually using this information to find new therapies that will improve the ability of humans to heal and regenerate better.

Graphene plasmonics beats the drug cheats
Graphene plasmonics beats the drug cheats
Writing , the scientists, working with colleagues from Aix-Marseille University , have created a device which potentially can see one molecule though a simple optical system and can analyse its components within minutes. This uses plasmonics – the study of vibrations of electrons in different materials.

A Clock Einstein Would Have Loved
A very special clock that can measure time on the basis of the mass of a single atomic or even subatomic particle holds promise not only for ultraprecise measurements of mass and time, but also for such exotic applications as testing Einstein's general theory of relativity, or the effects of gravity on antimatter.

3D colour X-Ray imaging improved for identifying contraband, corrosion or cancer
3D colour X-Ray imaging improved for identifying contraband, corrosion or cancer
Its ability to identify the composition of the scanned object could radically improve security screening at airports, medical imaging, aircraft maintenance, industrial inspection and geophysical exploration. The X-Ray system developed by Robert Cernik and colleagues from The School of Materials can identify chemicals and compounds such as cocaine, semtex, precious metals or radioactive materials even when they're contained inside a relatively large object like a suitcase.

Worms hijack development to foster cannibalism when needed
Worms hijack development to foster cannibalism when needed
Conventional wisdom holds that genes determine the shape and structure (morphology) of animals, but something else may be at play. A new study shows that a roundworm ( P. pacificus) regulates its offspring's morphology by using a potent cocktail of small-molecule signals. Exposure to trace quantities of these chemically unusual molecules can turn genetically identical juveniles into very different types of adults.

Scientists pinpoint molecular signals that make some women prone to miscarriage
Scientists pinpoint molecular signals that make some women prone to miscarriage
Scientists have identified molecular signals that control whether embryos are accepted by the womb, and that appear to function abnormally in women who have suffered repeated miscarriages. The research, carried out at Imperial College London and the University of Warwick , suggests these signals could be targets for drugs that would help prevent miscarriage in women who are particularly vulnerable.
