Wild turtles in Missouri may soon be protected from trappers, as the Missouri Department of Conservation proposed a ban this week on the commercial harvest of turtles in the state. 

Many wild turtles that are captured and exported from the United States are sold as exotic pets or processed into food and traditional Chinese medicine. Missouri is one of a few states in the country that doesn't impose a limit on how many wild turtles that trappers can collect.

At an experimental mine at the Missouri University of S&T in Rolla, scientists are setting off explosives around lab mice and cell cultures to study how exposure to blasts in combat damage the brains of military personnel.

Neuroscientists at the University of Missouri-Columbia and Stanford University are leading the research, funded by the U.S. Department of Defense. The study is focused on mild traumatic brain injury, the most common type of brain injury affecting military personnel. However, the condition is difficult to diagnose and not well studied.

The Great River National Wildlife Refuge in Annada, Missouri,  is acquiring two islands on the Mississippi River to protect wildlife and provide more areas for outdoor recreation. 

The U.S. Fish and Wildlife Service has given $677,500 to the refuge in northeast Missouri, a portion of $21.9 million the U.S. Department of the Interior dedicated to conserving public lands in 16 states. A family near the river used to farm on the 702-acre property, called Slim and Haps Islands, but stopped as flooding increased along the Mississippi River.

More than a hundred protesters marched in downtown Clayton on Sunday afternoon and demanded the release of 22 people who were arrested at the Saint Louis Galleria on Saturday.

It wasn’t so much of a protest as a vigil on Sunday as demonstrators gathered at the Justice Center in Clayton to wait for the release of the people arrested Saturday at a protest in the Galleria.

By 5 p.m., all 22 of those arrested had been released.

One week after a judge acquitted former St. Louis police officer Jason Stockley of murder in the 2011 death of Anthony Lamar Smith, protesters continued their push for change, taking their message Friday to the mostly white city of St. Charles.

Protesters blocked Brentwood Blvd. outside of the Galleria mall on Wednesday night as they chanted “for Anthony Smith and Michael Brown, shut it down, shut it down.”

Updated at 7:45 p.m. with mall closure — The advertised gathering spot Wednesday for people wanting to voice their displeasure with the Jason Stockley verdict was downtown Clayton.

That was a decoy, as protesters converged on the St. Louis Galleria and blocked traffic on busy Brentwood Boulevard in Richmond Heights, about a mile away. Both Clayton and the mall were targeted because of protesters’ strategy to disrupt business as usual in affluent communities.

Sikeston, Missouri — In front of several greenhouse scaffolds, Steve Hamra gestured to a metal cart containing trays of seedlings for bell peppers, tomatoes and romaine lettuce. About 150 miles south of St. Louis on a 10-acre site, Hamra is growing produce hydroponically, or in water instead of soil, for about 400 schools, in Missouri and other states.

Updated at 6:45 p.m. to recast throughout, add details about cleanup — When morning broke Monday, about 100 people already were in the streets of downtown St. Louis to silently protest the acquittal of former St. Louis officer Jason Stockley and high schoolers in the suburbs were walking out of classes.

It was the fourth day of action since a judge decided Stockley wasn’t guilty of first-degree murder in the 2011 shooting death of Anthony Lamar Smith. More than 150 people have been arrested since Friday’s verdict, including 123 people Sunday night in downtown, where businesses mended broken windows Monday.

An evening protest took place in the Delmar Loop, which hosted a largely peaceful demonstration Saturday before a few people broke several windows.

Updated at 3:25 p.m. Sept. 18 with release of Post-Dispatch reporter — More than 80 people were arrested Sunday night, St. Louis police said, long after the official — and peaceful — protests ended. The last group of people to be arrested downtown were boxed in by police and sprayed with a chemical agent, a livestream showed, and a St. Louis Post-Dispatch staffer tweeted that one of their reporters was among them. A Post-Dispatch editor this morning announced that reporter Mike Faulk has been released.

Visitors to the St. Louis Zoo will be able to watch two grizzly bear cubs from Montana starting Friday.

The male, Huckleberry and female, Finley, are both 2 1/2 years old. They and their mother were found disturbing residences and livestock, posing a risk to public safety. Montana wildlife officials killed the mother and sent the cubs to St. Louis Zoo, because zoo officials already had plans to revamp the grizzly bear exhibit.

As European regulators investigate the potential $66 billion Bayer-Monsanto merger, Bayer's CropScience division is preparing to address challenges in crop technology, especially those tied to Monsanto's products. 

At the annual Ag Innovation Showcase in St. Louis hosted by the Donald Danforth Plant Science Center, Adrian Percy, Bayer CropScience's head of research and development, said a priority for the merged companies would be addressing a decline in pollinators and meeting the high demand for herbicides to combat resistant weeds.

The city of St. Louis could soon commit to an ambitious goal to depend on renewable energy sources such as wind and solar power for its electricity by 2035. 

Board of Alderman President Lewis Reed introduced a resolution Friday that would completely transition the city away from using fossil fuels. The St. Louis region currently receives less than 5 percent of its electricity from wind, solar and other renewable sources.

Nearly 600,000 people in the Midwest are working in the clean energy sector and that number likely will continue to rise, according to advocates for the industry. 

The nonprofit groups Clean Energy Trust and Environmental Entrepreneurs released a report Thursday that demonstrated a significant increase in the past year in the number of people who work in fields such as wind and solar power and energy auditing. Illinois led the region's clean energy sector growth by adding nearly 120,000 jobs, largely in the area of energy efficiency. Missouri showed growth in multiple areas, including renewable energy, which saw jobs grow by 14.5 percent in the last year.

The SuperTIGER detects cosmic rays, high-energy radiation that's produced from supernovas. Researchers at Washington University and NASA will launch the 6,000 pound device over Antarctica in November.

In November, a team of scientists from Washington University and NASA will head to Antarctica to launch a device that will help them study space radiation. 

When massive stars die, they create explosions known as supernovas. Researchers theorize that the shocks from these events strip particles of their electrons and send them through space close to the speed of light. These high energy particles are called cosmic rays and studying them could help physicists understand the universe outside of our solar system.

The National Park Service has ordered the Missouri Department of Natural Resources to stop construction work for a proposed ice recreation facility in Creve Coeur Lake Memorial Park. 

In a letter to the Missouri Department of Natural Resources last Friday, the federal agency expressed its concerns about the St. Louis Ice Center.

"We are concerned that the Ice Center would act as a stand-alone attraction and would not encourage further outdoor recreation at the rest of the site," wrote Carol Edmondson, an outdoor recreation planner at the National Park Service.

The Missouri Department of Natural Resources has requested the U.S. Environmental Protection Agency upgrade Jefferson County's air quality status, now that levels of sulfur dioxide have dropped below the federal limit. 

In 2013, the EPA designated Jefferson County as "nonattainment," or not meeting the federal standard for sulfur dioxide, a gas that produces toxic odors and causes respiratory problems. A monitor near the Doe Run lead smelter in Herculaneum detected sulfur dioxide levels above 200 parts per billion, said Kyra Moore, director of the state's air quality control program. After the smelter closed in 2013, levels have dropped well below the 75 parts per billion limit.

Researchers are studying countless plants and animals to understand how climate change could threaten populations. At Saint Louis University, scientists want to know if changes in temperature could affect the mating songs of insects.  

Biologists at SLU have received $480,000 from the National Science Foundation to study how temperature affects treehopper mating songs, which could provide clues as to how climate change could affect insect survival. The loss of insect species could adversely affect agriculture and many ecosystems that depend on them.
