Microbes living in a hyena's scent pouch may actually be responsible for how it smells, as well as signaling its identity to other animals, according to microbiologists at Michigan State University.  The research was published Monday in the journal Proceedings of the National Academy of Sciences.

HealthSherpa lets users quickly shop for health insurance plans by ZIP code, and calculates their federal tax subsidy eligibility.  Unlike the federal and state exchange websites, the site does not force users to go through a lengthy sign up and application process to get their information.

Japanese Car Makers Getting to the Heart of the Matter

b_250_0_16777215_00_images_obgrabber_2013-11_31b40b7d46.jpgiStock/Thinkstock (NEW YORK) -- The car of the future is once again being crafted by Japanese engineers, and this one is really impressive. Researchers at Nippon Medical School are working on a model that will be able to warn a driver that a heart attack is looming or even tip off the motorist well in advance of possible heart disease. The car’s steering wheel will be set up for electrocardiographic monitoring as well as detecting pulse waves when blood flows from the heart.

Bad Diets Linked to a Lack of Education and a Lot of Movement

b_250_0_16777215_00_images_obgrabber_2013-11_dd1eeb91d3.jpgiStock/Thinkstock (BERLIN) -- Eating foods rich in fats and sugars -- in other words, the stuff that’s not good for you -- might have to do with how physically active you are. That level of activity also seems to tie in to the amount of education one has had, according to researchers at the Robert Koch Institute in Berlin. Study author Jonas Finger says that previous studies have shown those of lower economic status, typically with less schooling, often have poorer diets than other income groups.

Researchers at the University of Montreal presented these findings at the Neuroscience 2013 conference in San Diego on Sunday, providing moms-to-be with even more reasons to make exercise a priority.
