This week, the Centers for Disease Control and Prevention (CDC) issued a controversial report about pregnancy and alcohol use. “More than 3 million US women are at risk of exposing their developing baby to alcohol because they are drinking, having sex, and not using birth control to prevent pregnancy,” the CDC web site reads.

It's hard to keep friends around when you reek, so most of us wear antiperspirant or deodorant to suppress that offensive natural musk. But those personal care products are changing the populations of bacteria that live in our armpits, according to a new study published this week in the journal PeerJ.
You might not know it, but your sweat is pretty valuable. The varying chemical concentrations in sweat reveal your blood sugar level, whether you're dehydrated, or if your blood is not pumping fast enough to a particular tissue. Now a team of researchers led by scientists at the University of California, Berkeley has developed a Fitbit-like device that can detect and track the molecular components of sweat, according to a study published today in Nature. Devices like these could help doctors and fitness aficionados track multiple variables of athletes' health, and could someday provide a non-invasive test for medical professionals working to diagnose disease.
