Found: A new form of DNA in our cells
In a world first, Australian researchers have identified a new DNA structure – called the i-motif – inside cells. A twisted ‘knot’ of DNA, the i-motif has never before been directly seen inside living cells....

Study suggests method for boosting growth of blood vessels and muscle
As we get older, our endurance declines, in part because our blood vessels lose some of their capacity to deliver oxygen and nutrients to muscle tissue. An MIT-led research team has now found that...
Mysterious skeleton shows molecular complexity of bone diseases
A bizarre human skeleton, once rumored to have extraterrestrial origins, has gotten a rather comprehensive genomic work-up, the results of which are now in, researchers from the Stanford University School of Medicine report. The findings stamp...
Beneficial skin bacteria protect against skin cancer
Science continues to peel away layers of the skin microbiome to reveal its protective properties. In a study published in Science Advances on February 28, University of California San Diego School of Medicine researchers report a...
Bacteria play critical role in driving colon cancers
Patients with an inherited form of colon cancer harbor two bacterial species that collaborate to encourage development of the disease, and the same species have been found in people who develop a sporadic form...
Study proves ‘muscle memory’ exists at a DNA level
A study led by researchers at Keele University has shown for the first time that human muscles possess a ‘memory’ of earlier growth – at the DNA level. Periods of skeletal muscle growth are...
How alcohol damages DNA and increases cancer risk
Scientists have shown how alcohol damages DNA in stem cells, helping to explain why drinking increases your risk of cancer, according to research part-funded by Cancer Research UK and published in Nature today. Much previous research...
Why age? Should we end aging forever?
Why do we age and is there anything we can do about it? In the US, people can expect to live to about 77 years old on average. Is this the best we can...
Meteorites may have brought building blocks of life to Earth
Life on Earth began somewhere between 3.7 and 4.5 billion years ago, after meteorites splashed down and leached essential elements into warm little ponds, say scientists at McMaster University and the Max Planck Institute...
Genes that separate humans from fruit flies found
Genes which determine animal complexity – or what makes humans so much more complex than a fruit fly or a sea urchin – have been identified for the first time. The secret mechanism for...
