An endangered beetle will be making its Missouri comeback on Tuesday.

That's when about 250 American burying beetles will be reintroduced in the Wah’Kon-Tah prairie, about 60 miles northwest of Springfield.

It's a joint effort of the Nature Conservancy, the U.S. Fish and Wildlife Service, the Missouri Department of Conservation, and the St. Louis Zoo.

It's been 40 years since a confirmed sighting of the insect in Missouri, and the director of the zoo’s Center for American Burying Beetle Conservation, Bob Merz, says he hopes it will get reestablished in the state.

For those who think this may just be the warmest spring ever in Illinois, the state's climatologist has this to say: You're right.

In a news release, Jim Angel of the Illinois State Water Survey says March, April and May were warmer than at any time since records started being kept all the way back in 1895.

This year's spring temperatures averaged 59.1 degrees, or nearly 2 degrees warmer than the average temperature of 57.3 in 1977.

The average temperature of 48.8 degrees from January through the end of May was also the highest on record.

The current answer to that question is unclear, the Kansas City Star says, but in the last two years, scientists with the Missouri Black Bear Project have tagged 108 bears in Missouri.

Now, scientists have begun the third year of a project to document the increasing number of black bears in the state.

Hundreds of wildlife cameras and hair snare traps are in place around the state, ready for the Missouri Department of Conservation to count the bears and document their movements.

A new study by Washington University indicates that folic acid may be responsible for reductions in certain kinds of childhood cancer.

Kimberly Johnson is an Assistant Professor of Public Health at Washington University, she says  folic acid has been a supplement in enriched grains since 1998.

“The study says that there is a correlation between fortification of the food supply,  with folic acid and a reduction in the incidence of some types of childhood cancer,” says Johnson.
