New microbial genes responsible for bile acid conversion is a major step forward for gut health
As the owner of a human body, you re carrying trillions of microbes with you everywhere you go. These microscopic organisms aren t just hitching a ride; many of them perform essential chemical reactions that regulate everything from our digestion to our immune system to our moods.
One important set of reactions relates to fat absorption via bile acids. Our livers make these acids to help digest fats and fat-soluble vitamins as they travel through the small intestine.

In a first, scientists in Europe and the US have been able to partially restore the eyesight for a blind man who suffered photoreceptor disease nearly 40 years ago. Employing the technique known as optogenetics, which involves altering cells such that they manufacture the light-sensitive proteins, scientists were able to get the vision back for the 58-year old patient. Now, he can recognize people, do the counting, locate and touch different objects.  ....
