Scientists have sequenced 15 ancient genomes spanning from Alaska to Patagonia and were able to track the movements of the first humans as they spread across the Americas at “astonishing” speed during the last Ice Age, and also how they interacted with each other in the following millennia.
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.
Only a small proportion of cases of dementia are thought to be inherited – the cause of the vast majority is unknown. Now, in a study published today in the journal Nature Communications, a team of scientists led by researchers at the University of Cambridge believe they may have found an explanation: spontaneous errors in our DNA that arise as cells divide and replicate.
A new synthetic enzyme, crafted from DNA rather than protein, ‘flips’ lipid molecules within the cell membrane, triggering a signal pathway that could be harnessed to induce cell death in cancer cells.
An extinct strain of the human Hepatitis B virus (HBV) has been discovered in Bronze Age human skeletons found in burial sites across Europe and Asia.
Seventy-two new genetic variants that contribute to the risk of developing breast cancer have been identified by a major international collaboration involving hundreds of researchers worldwide.
A new study into the genetics underlying restless legs syndrome has identified 13 previously-unknown genetic risk variants, while helping inform potential new treatment options for the condition.
Family history and location of genetic fault affect risk for carriers of key breast and ovarian cancer genes20 Jun 2017
A large scale study of women carrying faults in important cancer genes should enable doctors to provide better advice and counselling for treatments and lifestyle changes aimed at reducing this risk.
Our DNA influences our ability to read a person’s thoughts and emotions from looking at their eyes, suggests a new study published in the journal Molecular Psychiatry.
Study finds that ancient Egyptians were most closely related to ancient populations from the Middle East and Western Asia.
