New research from Washington University provides the first evidence of a human antibody capable of protecting fetuses from the Zika virus. 

In pregnant women, the virus can cause severe birth defects, most notably microcephaly, in which infants are born with abnormally small heads. 

According to a paper published this week in the journal Nature, scientists tested multiple human antibodies on infected pregnant mice. One antibody, ZIKV-117, was able to defend the mice fetuses from all existing strains of the Zika virus. 

Wash U virologist Michael Diamond, a co-author of the study, said the finding makes significant progress in combating the virus.

Recent studies have indicated that wildfires such as the ones that have raged in the western United States could have a cooling effect on our climate. But early findings by engineers at Washington University suggest that wildfire smoke could have a warming effect on the atmosphere. 

Using material from forests in the west, Wash U scientists have been recreating wildfires in the laboratory to understand the effects such events have on climate and public health. Research predicts that wildfires could occur more frequently and for longer periods of time. A 2012 study suggests that the area burned by wildfires in the United States could double by 2050.

It would be an understatement to call Nick Norman an animal lover. A visit to his family's 200-acre property in St. Clair, Mo., will reveal quickly that his mission in life is to save them.

For example, he has shared his home with Charlie, a 170-pound African spurred tortoise. When Norman found Charlie, he was a malnourished company mascot. Charlie now spends his days marching slowly around Norman's yard, feasting on watermelons.

Madison County leads the state in vehicle crashes involving deer, and November is the most at-risk month for such accidents, according to the Illinois Department of Transportation.

Eight people died, and more than 600 were injured in 2015 in 15,754 vehicle-deer accidents in the state. Nearly 45 percent of those crashes occurred in October, November and December. There were 440 accidents in Madison County followed by Cook County with 431. By comparison, St. Clair County reported 212 crashes involving deer.

Think of the night sky when you look up through the smog of the city. Then, think of that same sky on a clear night in a rural area.

That’s the difference between two images of a 90-year-old man’s brain, after he passed away and donated his body to Alzheimer’s disease research. Both scans are dark blue, with points of light showing plaques consistent with the disease. But the sharper image uses a new compound developed by researchers at Washington University in St. Louis.

St. Louis developers of genetically-modified organisms have called into question a New York Times report that compares the yields of genetically modified crops between North America and Europe.

Using data from the United Nations, an investigative report published over the weekend by the Times claimed that "genetic modification in the United States and Canada has not accelerated increases in crop yields or led to an overall reduction in the use of chemical pesticides." Agriculture in the United States and Canada has embraced GMOs, while many European countries have banned cultivation of them for many years. The article also cites a National Academy report released this year that said there is no evidence that using GM crops have accelerated yield. 

In a statement released Monday, Monsanto said that it's tough to compare yields between large geographic areas, such as the United States and Europe.

For three months, 32-year-old Tara Hegger has lived in the intensive care unit at Mercy Hospital.

She passes the time listening to music, visiting with family members and watching TV, mostly comedies. They keep her mind off of a painful decision that inches closer every day.

“The social worker came to me and basically told me I had to leave, because my days ran out," Hegger said, pausing between the pumps of oxygen provided by a ventilator next to her. "I had to make a choice.”

Like other Missouri patients in her situation, she will have to leave the state to find a nursing home that accepts her insurance — a dilemma tied to the state's low Medicaid reimbursement rate for long term care.

Carolina Hidalgo | St. Louis Public Radio

In a community garden in central St. Louis, Saint Louis University biologist Gerardo Camilo walked methodically, scanning the plants while holding a butterfly net. Then, he stopped and stared intently at a patch of impatiens. 

He was pursuing a bee that was weaving in between the stems of the flowers. In one fell swoop, he swung the net down and clutched the net with a fist to trap the bee inside. He examined his captive with a quizzical expression. 

"Wow! I have never seen this in my life," Camilo said. "What the hell are you?"

Camilo and other scientists have found that bee populations are abundant and very diverse in urban areas, compared to rural areas, a finding that could help save endangered bees, important pollinators.

Since the Mid-East Area Agency on Aging saw its funding slashed by about $2 million during the recession, the agency has had to piece together grants for major projects.

“We’ve had to close senior centers over the years because we can’t support the number that were originally being utilized. And yet at the same time the population is growing,” Director Mary Schaefer said.

That could soon change. On Nov. 8, voters in St. Charles County, St. Louis County and the city of St. Louis will see a box for “Proposition S” on the ballot. The initiative would increase property taxes to pay for programs for seniors, to help them continue living at home.

The eastern St. Louis metro area has been particularly hard hit by health insurance companies exiting the Affordable Care Act exchange. This week, the federal government released prices for 2017, which include substantial increases in western Illinois.

Insurance brokers in Belleville say three Metro East counties — St. Clair, Madison and Monroe — will have just one insurer to choose from this year: Blue Cross Blue Shield.

In Missouri, 27 percent of  carbon emissions are caused by the transportation sector, according to a national report. 

Local environmental advocates are using the findings by the nonprofit think tank, Frontier Group, to argue that providing more carbon-neutral transportation options could improve public health and safety. The report includes multiple policy recommendations to reduce transportation's impact on the environment, including incentives for consumers to purchase electric cars and creating more paths for pedestrians and bikers.

Police departments, recreation centers and a handful of grocery stores will accept and dispose of unused medications in the St. Louis region as part of a semi-annual National Prescription Drug Take-Back Day on Saturday.

Public health officials recommend that people dispose of unused medications to prevent accidental poisoning or addiction. While flushing pills down the toilet may be effective, it can contaminate the water system. With that in mind, a growing fixture at the take-back days are plastic disposal pouches, filled with a carbon compound. They can hold up to 45 pills, and a once cup of water is added, the mixture breaks down into a substance that is safe for a landfill.

This story was updated Oct. 20 with a response from Republic Services — The Missouri Department of Natural Resources has ordered Bridgeton Landfill LLC owner Republic Services to study the increased groundwater contamination detected at the site.

In a letter addressed to Republic Services engineer Erin Fanning last Friday, MDNR engineer Charlene Fitch provided a detailed review of groundwater sampling reports that span from October 2014 to April 2016. The sampling was conducted by a contractor hired by Republic Services. It noted increasing levels of hazardous substances that exceed federal levels, particularly benzene, which can increase the risk of cancer to those exposed to it.

Outdoor activities like hiking and camping can help people appreciate nature and encourage public support for conservation, but a new study finds that such recreation can also be harmful to the environment. 

In the most comprehensive survey of threats to rare plants conducted in 20 years, researchers from the Missouri Botanical Garden and the University of Missouri-St. Louis analyzed data on threats to nearly 3,000 rare plants in the United States. As scientists report in the journal Biological Conservation, they discovered that outdoor recreation was the most common threat to plants, above residential development and agriculture.

Rates of three common sexually transmitted diseases have risen to a record high level nationwide, and St. Louis continues to rank high among cities, according to federal data released Wednesday.

The St. Louis region recorded 14,961 cases of chlamydia in 2015, the 17th highest per-capita rate in the country. Rates of syphyllis stayed relatively steady at just over 400 cases in the metro area. The city of St. Louis, however, measured the highest rate of both chlamydia and gonorrhea among counties and independent cities. 

“We’ve seen closures of publicly funded STD clinics around the country, and St. Louis is similar in that we have very few options for people to get tested and treated,” said Dr. Brad Stoner, medical director of the St. Louis STD/HIV Prevention Training Center.

In 1960, Jane Goodall saw two chimps remove the leaves off of small twigs and used them as tools to fish for termites in the ground, which they ate.

It was the first time a scientist observed chimpanzees turning an object into a tool and using it for a specific purpose. But it was unclear how the chimps learned to do this. More than 50 years later, scientists have for the first time captured videos of chimpanzee mothers teaching their offspring to fish for termites.

The footage, taken in the Republic of Congo by researchers from the Goualougo Triangle Ape Project and Washington University in St. Louis, show several examples of mother chimpanzees handing termite fishing tools to their young.

Some scientists dream of a future in which people can add sorghum, intermediate wheatgrass and other currently wild perennial plants to their diet.

In St. Louis, researchers at the Missouri Botanical Garden and Saint Louis University are developing a list of wild perennials, which live for many years, to recommend for domestication. Researchers say such plants have the potential to make agriculture more sustainable and feed a growing human population.

A federal initiative to find cures for brain disorders is granting $3.8 million to Washington University researchers and their collaborators.

The group is studying how neurons respond to light by implanting fiber-optic threads the width of a human hair into the brains of lab mice.

“We’re able to get animals to do particular behaviors while this light is dialing up or dialing down particular activities,” said Dr. Michael Bruchas, a Washington University neuroscientist. “We can actually affect how they approach one another, how they interact.”

It took hundreds of millions of years to populate oceans with its vast array of wildlife from plankton up to Coral Reefs and blue whales. It only took a few decades for humans to extract 90 percent of the big fish in the ocean and cut the number of Coral Reefs in half, said Dr. Sylvia Earle, a famous oceanographer and National Geographic Explorer-In-Residence.

A Missouri state representative from St. Louis County is launching a coalition to prevent the shooting deaths of children who find a loaded weapon in the home. The Children’s Firearm Safety Alliance will work with Washington University researchers to build a database tracking accidental shootings nationwide.

“First of all, you need to know what the numbers are. You need to know what the incidents are. We also need to know if adults are charged with anything in their states,” said Rep. Stacey Newman, D-Richmond Heights.

At least 95 children in the United States have been shot and killed accidentally so far this year, according to the database.

Four neighborhoods in south St. Louis could look a lot cleaner in the next couple years, thanks to new local efforts to address illegal dumping.

The "So Fresh, So Clean, So Creative Southside St. Louis" project, initiated by the Dutchtown South Community Corporation, recently received a $120,000 grant from the Environmental Protection Agency.

The two-year grant will fund efforts to educate residents on how to report illegal dumping, which is common in the neighborhoods of Dutchtown, Marine Villa, Gravois Park and Mount Pleasant. DSCC is working with the nonprofit group Brightside St. Louis to help with cleanup and education efforts.

Durrie Bouscaren | St. Louis Public Radio

NAMULONGE, Uganda — Before rows of tall, green bushes, Jude Aleu picks a cassava tuber off the ground and cracks it in half.

That shouldn’t be so easy. Healthy cassava tubers — a staple food crop in the region — can grow as thick as your upper arm. But the root in Aleu’s hands is stunted and gnarled because of a plant virus called brown streak disease. When he breaks it open, the flesh is streaked with brown and yellow, a necrosis that will render the harvest inedible.

“It’s corky,” said Aleu, a cassava safety manager for Uganda’s National Crops Resources Research Institute. “This root you cannot eat. Even animals cannot eat it.”

A set of construction standards that lower environmental requirements for new residential buildings could soon be approved by St. Louis County officials. 

The county's Building Code Review Committee has approved a draft ordinance on the building codes. The proposed ordinance, which will be sent to the county's Building Commission, dismisses energy efficiency measures from the 2015 International Energy Conservation Code (IECC) that would require new homes to reduce air infiltration, install more energy efficient lights and add more increased wall and ceiling insulation.

Students make signs on campus at Washington University before the start of the presidential debate on Sunday.
Carolina Hidalgo | St. Louis Public Radio

It took just a few minutes for the Affordable Care Act to feature in Sunday’s presidential debate between Democratic nominee Hillary Clinton and Republican nominee Donald Trump as Trump quickly blamed the legislation for the rising cost of health care.

“When I watch what’s happening with some horrible things like Obamacare where your health insurance and health care is going up by numbers that are astronomical,” Trump said, adding that costs have gone up as much as 71 percent.

The Trump campaign has not said where he obtained his figures. But even though premiums are rising, the effect is concentrated on plans sold on the individual market not those that are provided through an employer.
