A major international study of the genetics of breast cancer has identified more than 350 DNA ‘errors’ that increase an individual’s risk of developing the disease. The scientists involved say these errors may influence as many as 190 genes.

Researchers at the University of Cambridge have uncovered a specialised population of skin cells that coordinate tail regeneration in frogs. These ‘Regeneration-Organizing Cells’ help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues.

In the largest study of its kind to date, Cambridge researchers have looked at why some people manage to stay thin while others gain weight easily. They have found that the genetic dice are loaded in favour of thin people and against those at the obese end of the spectrum.

Scientists have created the most comprehensive method yet to predict a woman’s risk of breast cancer, according to a study led by researchers at the University of Cambridge. The study, funded by Cancer Research, is published today in Genetics in Medicine.

Evidence has been building in recent years that our diet, our habits or traumatic experiences can have consequences for the health of our children – and even our grandchildren. The explanation that has gained most currency for how this occurs is so-called ‘epigenetic inheritance’ – patterns of chemical ‘marks’ on or around our DNA that are hypothesised to be passed down the generations. But new research from the University of Cambridge suggests that this mechanism of non-genetic inheritance is likely to be very rare.
