Why Scientists Are Trying Viruses To Beat Back Bacteria

Not all viruses are bad for us. Some of them might even help up us fight off bacterial infections someday.

Naturally occurring viruses called bacteriophages attack specific types of bacteria. So researchers at the University of Leicester decided to try and take advantage of phages' bacteria-d... Read More

Scientists Turn Dr. Frankenstein, Re-Write Bacteria’s Entire Genome

It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.

The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More

Much breast milk bought online is contaminated, analysis shows

Desperate for breast milk, some new mothers who can't nurse their babies are turning to online sources, typically strangers with ample supplies. But a new study finds that human milk bought and sold on the Internet may be contaminated — and dangerous.

Nearly 75 percent of breast milk bought t... Read More
