Scientists at Washington University in St. Louis are developing a test for the Zika virus that produces results quickly and don't require refrigeration. 

To test for the Zika virus, which is transmitted by mosquitos and is linked to birth defects, blood samples have to be sent to a laboratory, where a positive or negative result is generated in a couple days. The blood and the chemicals used in the test have to be refrigerated. Researchers at Wash U's medical and engineering schools created a test for the virus using nanotechnology, or particles smaller than 100 nanometers. It shows results in a matter of minutes.

Adly Castanaza, nurse from Jalapa, Guatemala, guides the probe of a portable ultrasound over the belly of a volunteer in St. Louis. It’s the same machine she’ll use back in Guatemala, to measure how pregnant women, their children and the elderly are affected by smoke from cook stoves.  

“I have seen, when I was in the hospital, so many people who come from rural communities that have [chronic obstructive pulmonary disease],” Castanza explained. “We have to know exactly if there’s a relation(ship with air pollution).”

Washington University in St. Louis is training health workers from India, Rwanda, Guatemala and Peru to conduct a massive study on how the smoke from traditional cook stoves affects women and children.

A mind-controlled robotic glove under development by Washington University scientists could give hope to those whose hands have become paralyzed due to a stroke. 

In the journal Stroke, researchers reported some success with using the device, called the Ipsihand, to help stroke patients regain the ability to grasp objects. A  group of 10 patients wore the robotic exoskeleton over the hand, wirelessly connected to a cap fastened to the head that reads brain signals that tell the hand to open and close.

Antiobitic resistance is a big concern in the medical community these days. On Wednesday's St. Louis on the Air, we turn our attention to the issue.

When Meredith Littlejohn died, her parents Steve Littlejohn and Stefanie London had spent over a year in and out of the hospital with her for treatment of Acute Myeloid Leukemia. It wasn’t AML that killed Meredith, but rather an antibiotic-resistant infection she developed in the hospital while her immune system was compromised.

Antibiotic-resistant infection is a rising issue in American society and thousands of people die each year when they develop infections that no antibiotic can control.

Before the end of March, scientists from Washington University in St. Louis plan to burn parts of an Ozark forest about 30 miles outside of St. Louis. 

Research has shown that repeated burning of forests can help increase the variety of plants that live in a forest. That's particularly the case for plants that live under the forest canopy, said Jonathan Myers, a Wash U biology professor and a member of the Tyson Research Center in Eureka. Having more kinds of  wildflowers can attract native insects that pollinate plants that animals eat.

About five years ago, Doug Wiens, a seismologist from Washington University in St. Louis, went knocking on the doors of farmers in Minnesota and Wisconsin. He asked them if they would let him and his team of geologists place seismometers, devices that measure the earth’s movements, on their land.

The farmers were a little suspicious.

“‘Why are you doing this here? Are you exploring for oil? Nobody’s done anything like this before,’” Wiens recalled them asking. “And so, we would show them this gravity map and we’d say, ‘Well, there’s this really unusual feature here and we want to study that.’”

A recent study published in the medical journal “Pediatrics,” has found that depression is on the rise among teenagers, particularly in girls. It also found that the percentage of young people with a major depressive episode who are seen by a primary care provider for those occurrences has not increased concurrently.

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.

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.”

On Sunday, Oct. 9, the eyes of the world turned to St. Louis as Washington University hosts the second presidential debate between Donald Trump and Hillary Clinton. We’ve laid out some of the things you need to know ahead of the debate (like road closures and the cost of such an event) here, but we’re also working to bring you updates day-of from our reporters and producers with St. Louis Public Radio.

With Republican Donald Trump’s presidential campaign in crisis mode one day before a pivotal debate in St. Louis, at least two area GOP officials want their party's nominee to step aside.

U.S. Rep. Ann Wagner, R-Ballwin, and Illinois Congressman Rodney Davis, R-Taylorville, both released statements on Saturday pulling their support for Trump. Their retractions came a little less than a day after the Washington Post’s explosive story detailing Trump’s vulgar comments about women that were captured on tape in 2005.

After a little bit of time away, the national spotlight is back on St. Louis.

Hordes of reporters and political types will venture here this weekend for the second presidential debate between Republican Donald Trump and Democrat Hillary Clinton.

This area has a lot in common with what’s forming the national political discourse. Our racial, social and economic divisions were broadcast to the world after Michael Brown’s death in Ferguson. And finding tangible solutions to these longstanding gaps has been a slow and frustrating process.

Reaching younger voters may be one benefit of using college campuses for presidential debates.  Which, no doubt, is one of the goals for Donald Trump and Hillary Clinton as they prepare to take the stage Sunday at Washington University.

A recent campus debate at Wash U between the college Republicans and Democrats offers a window into the candidates’ dilemma, as they seek to woo millennials, many of whom don’t align themselves with either major party.

Updated Thursday, Oct. 6 at 1:20 p.m. with traffic closure details  Last Monday night featured the first presidential debate of the year and the first time Hillary Clinton and Donald Trump faced off one-on-one over plans and policy. It was the most-watched debate in televised debate history.

But what about the second round? In addition to a different format, a town hall, the second debate is at Washington University. It has hosted more debates than any other institution in history.

Since the presidential campaign began in earnest, it’s become fairly common for candidates to allude to the aftermath of Michael Brown’s shooting death at the hands of a Ferguson police officer.

But according to officials that represent Ferguson, neither Hillary Clinton nor Donald Trump has visited the city since announcing their presidential bids. And with both candidates set to debate Sunday at Washington University, some of the city’s elected leaders say it’s time for Trump and Clinton to see the town for themselves.

As Washington University gets ready to host the second presidential debate on Sunday night, 18 of the school's freshmen are not only learning about how the face-offs affect who will win the White House. They’re also excited to cast their first presidential ballots.

In class, history Professor Peter Kastor and his students engage in lively debates themselves, about how the candidate sessions shape the election. And, Kastor said, they have many questions for him.

About 30 Washington University students are competing for funds to develop projects to reduce gun violence this weekend.

It’s the latest effort in the university’s on-going gun violence initiative launched almost a year and a half ago.

“We want more student involvement in this public health issue. And also we want them to come up with innovative ideas on how we can solve gun violence since usually (the ideas come) from researchers,” said initiative coordinator Poli Rijos.

A giant balloon will soon provide scientists at Washington University in St. Louis a view of black holes in the Milky Way galaxy.

Researchers will launch the 40 million cubic foot unmanned balloon, carrying an X-Ray telescope named X-Calibur, this month from NASA’s Columbia Scientific Balloon Facility in Fort Sumner, N.M. The payload will ascend 126,000 feet into the stratosphere, which is about four times the cruising altitude of commercial airplanes.

Imagine a day when law enforcement could rely on a tiny tool to scope out bombs hidden underground in potentially dangerous places.

That day could come soon, if scientists at Washington University in St. Louis have success with tapping the potential of locusts. Relying on locusts' keen sense of smell, researchers are building devices that use the insects' olfactory system to improve homeland security.

Cardinals are known for their bright red plumage, a color that gives birds an advantage when attracting mates. But what gives them this attractive hue?

It’s all in the genes, say scientists at Washington University in St. Louis.

Children who live with persistent asthma in childhood are at a higher risk of developing lung problems later in life, according to new findings from a national asthma study that began in the 1990s. A small number of patients even exhibited symptoms of chronic obstructive pulmonary disease, or COPD, in early adulthood.
