Legislation like the Clean Water Act has helped check the effluent flowing into rivers and streams. Though that fight is far from over, a new, all-too-modern danger has meanwhile seeped invisibly into waters around the world: legal and illegal drugs. And their effect on the ecosystem is poorly understood.

Due to the intense nature and duration of the post-9/11 conflicts, the United States has needed to help an increasingly large pool of veterans who require long-term medical and mental health care. More than 1 million Americans served in the Iraq war alone.

A new study suggests young women who are not heterosexual are at a greater risk of accidental pregnancy, partly because they are less likely than straight women to use contraceptives.

Demand for sugar in the United States grew throughout the 20^th century. But it skyrocketed when the food industry began mass producing high-fructose corn syrup (HFCS) in the 1970s. Though HFCS intake has fallen in the new millennium, researchers still struggle to understand how this hotly debated sweetener impacts our health.

Each year as the weather warms, crowds of families and tourists flock to the beaches. People sometimes don’t realize the risk they take when they enter the ocean, a vast aquatic habitat. Newsrooms in coastal communities are well aware that when humans and wildlife interact, the results can be tragic – especially when sharks make an appearance. Even a minor run-in with a shark can send someone to the emergency room for surgery and stitches.

As parents and policy-makers look for insights into how to best prepare children for the future, research is focusing on the long-term implications of early development and behavioral patterns. One key factor is children’s degree of self-control, which includes attributes such as the ability to delay gratification, conscientiousness and willpower.

Globally, lung cancer is the leading cause of cancer-related death, and recently surpassed heart disease as the leading cause of smoking-related mortality. The National Cancer Institute estimates that this year in the U.S., more than 222,000 men and women will be diagnosed with the disease and 157,300 will die. The high mortality rate is in part a consequence of the difficulty in diagnosing the disease. Using chest X-rays, physicians typically discover lung cancers only at an advanced stage.
