Currently, in order to reshape cartilage such as that within the nose, incisions and subsequent sutures are typically required. Not only is the procedure invasive, but it can also result in scarring. Now, however, scientists have demonstrated a new method of cartilage-reshaping that requires no cutting.
One of the many ways scientists are working to unravel the mysteries of Alzheimer’s is by conducting experiments on mice that have been genetically engineered to develop the disease. Researchers pondering the protective potential of compounds found in green tea and carrots have again taken this route and returned some promising results, with the Alzheimer’s mice demonstrating unimpaired cognitive function following a carefully designed bout of treatment.
The earlier cancer is detected, the better the odds of treating it. But of course tumors can be hard to spot until they get to a certain size, at which point it might be too late. Now MIT researchers have developed a new optical imaging system that could be used to spot tiny tumors deep inside the body.
While the advent of 3D printers is commonly thought of as a revolution for manufacturing, it could have huge benefits for medicine as well. To help patch up large wounds that might normally require a skin graft, researchers at Wake Forest Institute for Regenerative Medicine (WFIRM) have developed a new bioprinter that can print dual layers of a patient’s own skin directly into a wound.
Generally, there are two types of twins in humans – identical and fraternal. But now, researchers have announced that twins born in Queensland, Australia, have been found to belong to an extremely rare in-between type known as “semi-identical” twins. This is only the second known case in the world, and the first time it has been identified during pregnancy using genetic testing.
