Researchers are developing a prosthetic hand that can be wired into the nerves and can sense shapes and degrees of stiffness of objects.

In a surprising scientific breakthrough, researchers have found out that the skin communicates with the liver.

This could explain how some skin diseases can also affect the rest of the body.

Another reason why sleep is important – it seems to clear your brain of toxins. During sleep, the flow of fluid around the brain increases, washing away any buildup of waste proteins. This could explain the link between sleep disorders and brain disease such as Alzheimer’s disease.

The research was published in Science.

Perhaps your mother was right – not enough time playing outside could make you shortsighted. Shortsightedness (nearsightedness or myopia) is increasing in the US, Europe and Asia, with around a third of US adults and almost 95% of young men in Seoul and college students in Shanghai now shortsighted. Researchers believe that this could be a lack of bright light. Read more in ScienceNews.

People with Hirschsprung disease have no nerves in parts of their bowels. Researchers have transplanted nerve stem cells into mice and found that they rewired the nervous system and connected with muscles.

A study of faecal transplants had to be stopped early because it was so successful – it was three to four times more likely to cure the difficult to treat gut infection Clostridium difficile than the strong antibiotic vancomycin.

While they might sound gross, faecal transplants from healthy donors, administered via a tube up the nose,  are turning out to be very effective at halting these very nasty infections. An alternative could be a dose of synthetic poo.
