Researchers at Washington University School of Medicine have shown a relationship between daily sleep patterns and a protein associated with Alzheimer’s disease.

The researchers found that levels of the beta amyloid protein in spinal fluid increased during waking hours and decreased during sleep.

Wash U neurologist Randall Bateman says that pattern was strongest in young, healthy test subjects. It lessened in people over sixty, and disappeared altogether in Alzheimer’s patients.

The Asian elephant calf Kenzi is making her public debut this morning at the Saint Louis Zoo.

The three-month-old calf will be on view at the "River's Edge" habitat from 10 a.m. to noon and then again from 1:30 to 3:30 p.m. today through Sunday.

A new report released today by the advocacy group Environment Missouri ranks St. Louis as the 10th smoggiest metropolitan area in the country.

Demolition of the former Chemetco copper smelter took another step forward on Tuesday. The demolition is the start of a long clean-up process for the hazardous Metro East eyesore.

The Illinois EPA is overseeing the dismantling of the smelter buildings, which began last year.

In the wake of the 9/11 attacks, more than 50,000 rescue and recovery workers converged at the World Trade Center. Among them were the 62 members of Missouri’s FEMA Urban Search and Rescue task force.

The experience at ground zero made many workers sick, with health problems ranging from asthma to post-traumatic stress disorder.

Soon after the terrorist attacks of 9/11, letters laced with anthrax started appearing in the U.S. mail, killing five people and sickening 17 others.

The incidents triggered a surge in research dedicated to preventing future bioterrorism attacks.

St. Louis Public Radio’s Véronique LaCapra spoke with Washington University virologist David Wang about his research on emerging infectious diseases, and how his work is helping to combat bioterrorism.

Missouri is doing a better job of getting toddlers vaccinated for childhood diseases.

Results of the CDC’s National Immunization Survey show Missouri rose from last in the rankings in 2009 up to 39th last year.

Washington University's Center for Obesity Prevention and Policy Research and the Missouri Foundation for Health have launched a "first-of-its-kind" website with information on obesity-related policy for organizations across the state.

The site, named "Policy Lift" has a variety of different functions, as an announcement about the site describes:

The Environmental Protection Agency is fining Washington University for failing to tell tenants about lead paint hazards in some of its married student housing units. The violation will cost the university close to $28,000.

The civil settlement involves three rental apartments northeast of Washington University’s Danforth campus.

The consent agreement says that between 2008 and 2010, the university failed to tell student tenants about previous citations for lead paint violations from the City of St. Louis Health Department.

A St. Louis County private school has received a $21.5 million donation from the James S. McDonnell family.

Mary Institute and St. Louis Country Day School, or MICDS, will use the money to build a new, 52,000 square-foot science and math facility.

MICDS head of school, Lisa Lyle, says the goal is to involve students in the process of scientific research.

The Missouri Foundation for Health has named a new president and CEO.

Robert Hughes will assume his new post on Nov. 1, taking over from founding president James Kimmey who is retiring at the end of this year.

Hughes is an Illinois native but has spent the past 20 years in New Jersey. There, he worked for the Robert Wood Johnson Foundation, the largest health philanthropy in the U.S.

A decade ago, more than one in four Missourians smoked. Now, only about one in five smoke, and those who do smoke are doing so less often.

Two men in Illinois are the first human cases of West Nile virus in the state.

The Illinois Department of Public Health says a Cook County man in his 80s got sick earlier this month. A 30-year-old from south-central Illinois became ill in July. In 2010, the first human case was reported on Aug. 31 - 61 people eventually tested positive.

The EPA today issued its decision on Missouri's water quality standards, approving how the state categorized 244 streams, rivers and lakes.

That decision means water bodies newly designated for high contact uses like swimming will need more protection.

Some sewage treatment plants, municipalities and others will need to start treating their wastewater discharges.

A new study out of Saint Louis University suggests that a child’s first doses of flu vaccine can be given as either two shots or two nasal sprays, but that giving one shot and one nasal spray may be most protective.

Lead researcher Dr. Dan Hoft says the nasal spray – which is a live vaccine – can cause wheezing. But it’s more effective than an inactivated vaccine, which is injected.

Hoft says this initial study suggests giving children one injection and one nasal spray may provide better protection against the flu, without the respiratory side effects.

Gov. Pat Quinn has signed legislation creating a commission to ensure minorities and the poor aren't disproportionately affected by environmental pollution.

The Environmental Justice Act was sponsored by Democratic Sen. Toi Hutchinson of Chicago Heights and Rep. Will Davis of East Hazel Crest.

The Environmental Protection Agency says testing near the old Carter Carburetor plant in north St. Louis shows offsite contamination is too low to cause health problems.

The EPA tested air, soil, and sediments in a one-block radius around the plant for PCBs, dioxins, and other industrial pollutants.

A new study shows that despite decades of effort to reduce nitrate pollution in the Mississippi River Basin, concentrations remain as high today as they were in the 1980s.

The U.S. Geological Survey conducted the study, which looked at nitrate levels at eight sites on the Mississippi, Iowa, Illinois, Missouri, and Ohio rivers.

USGS hydrologist and study lead Lori Sprague said the next step will be to figure out where the pollution is coming from.

The National Park Service is bracing for the possible loss of more than 900 trees near the Gateway Arch. That’s what could happen if the emerald ash borer makes it to the St. Louis area.

The emerald ash borer has killed millions of ash trees since it was accidentally introduced to the U.S. in the early 1990s.
