History of Medicine : The Stethoscope

In the early 1800s, doctors began to listen to patients' chests to diagnose diseases of the heart and lungs. At first, the physician put his ear to the patient's chest. One day when examining a young lady under the watchful eye of her family, René Laënnec was embarrassed to place his head right next to her breast. Instead, he listened through a rolled up a piece of paper, and found he could hear much more clearly than without it--thus the stethoscope was invented.

World Population Day - 2012 Theme: Universal Access to Reproductive Health Services

          "On this World Population Day, I call for urgent, concerted action by Member States to bridge the     gap between demand and supply for reproductive health care. We must mainstream reproductive health and rights into all development and poverty reduction plans. Investing in universal access to reproductive health is a crucial investment in healthy societies and a more sustainable future."

2012 Theme: Universal Access to Reproductive Health Services

As the world population edged to 7 billion people in 2011 (up from 2.5 billion in 1950), it has had profound implications for development. A world of 7 billion is both a challenge and an opportunity with implications on sustainability, urbanization, access to health services and youth empowerment.

Study of the Day: To Teach Kids to Eat Smart, Parents Should Show, Not Tell

New research from Michigan State University shows that leading by example promotes healthier diets among children than explicit food restrictions.

PROBLEM: How does parental behavior during mealtime influence children's food intake, weight, and obesity risk?

METHODOLOGY: To explore the possible consequences of directive (overt) and nondirective (covert and environmental) forms of parental feeding control, Michigan State University researchers led by Megumi Murashima collected data from 330 dyads of children, aged three to five, and mothers participating in a federal preschool program for low-income families. They assessed the moms' feeding practices, the kids' food consumption, and the height and weight of both the mothers and children.

Infographic: The Mountains of Salt in Processed Food

You already know that salt intake is highly correlated with high blood pressure and heart disease. And you probably have a vague sense that processed foods contain a lot of salt. But the specifics are truly terrifying, as this graphic by Next Generation Food shows.
It's not exactly the most legible graph--I mean, triangles aren't exactly a case study in information clarity. But the point comes through. Check out, for example, that fact that a single Burger King Whopper with cheese has 75% of your recommended daily salt intake; and the fact that Americans eat 250% of their recommended daily allotment:
