A federal appeals court has vacated an EPA rule that would have limited the amount of power plant pollution that drifts across state lines.

Unlike their cold-weather relatives, Humboldt penguins live only in South America, along the rocky Pacific coast of Chile and Peru. The Saint Louis Zoo’s Michael Macek has been monitoring the penguins there, tracking their health and numbers.

According to a new study, the Midwest is getting hotter. With this summer's record-breaking temperatures, that probably doesn't sound like news.

But a new report by the Union of Concerned Scientists shows our hot weather isn't an anomaly - things have been heating up across the Midwest for the past six decades.

The study found that on average, some Midwestern cities like St. Louis now have twice the number of very hot, humid, summer days as it did in the 1940s. Nighttime temperatures are also on the rise, and heat waves of three or more days are becoming more common.

Pediatric leukemia is a cancer of the blood and bone marrow. There are about 3,000 new cases in the United States every year, typically in children between the ages of four and six.

With treatment, about three-quarters of affected children are able to beat the disease.

But for those with what’s known as “high risk” leukemia, the odds of survival are much worse.

A new report by the Missouri Foundation for Health estimates that about two-thirds of Missouri’s more than 800,000 uninsured could get health insurance under the federal health care law. The county level data suggest that rural counties will benefit the most.

The fast food chain Hardee’s says it will stop buying pork from suppliers who use gestation crates – the cramped metal cages where many industrial pork producers house pregnant sows for most of their adult lives.

Some of Missouri's largest insurance companies will be refunding consumers almost $61 million this month under a provision of the federal healthcare law. Insurers who failed to spend at least 80 percent of premium-dollars on medical care and quality improvement have to repay the difference to consumers.

As part yesterday's Supreme Court decision on Obama's health care law, the justices ruled the federal government can't revoke states' Medicaid funding for failing to comply with the law's required Medicaid  expansion. And as Véronique LaCapra reports, that could leave some Missourians without access to health insurance.

The bacterium Enterococcus faecalis, which lives in the human gut, is just one type of microbe that was studied as part of the Human Microbiome Project funded by the National Institutes of Health (NIH).

Researchers have completed the first comprehensive census of the human “microbiome” — the trillions of bacteria, viruses, and other microorganisms that live in and on our bodies.

A new study out of Washington University has found that the 2-1-1 phone information system could be an effective tool to fight cancer in low-income and minority communities.

Across the U.S., people can call 2-1-1 to get help with housing, food, and other social service needs.
