Sometimes a spoonful of sugar helps the medicine go down; or in this case, the vaccine. A new study released by mBio shows that combining β-(1-3)-D-glucans (long chains of the sugar glucose) with an antigen creates a potent vaccine platform that could eventually be put to clinical use.
An ... Read More
The variety of bacteria in the digestive tract is strongly linked to whether a child will develop type 1 diabetes, according to a new study.
The connection could give doctors an early test for the condition and lead to new treatment for the disease.
There appears to be little or no genetic... Read More
In a potential breakthrough in the prevention of AIDS, researchers are reporting today that a vaginal gel containing an existing AIDS drug can cut in half a woman's chances of getting HIV from an infected partner.
The women involved in the study used it only 60 percent of the time, and it was... Read More
We think of ourselves as individuals — perhaps, in philosophical moments, as the merger of body and soul. Most of us are barely aware of the estimated 10 trillion individual cells that make up the human body or of the 100 trillion or more bacteria that live collaboratively and benignly within an...
