With mounting concern over climate change, scientists around the world are looking for ways to keep carbon dioxide out of the atmosphere.

A team of geologists and engineers at Washington University is testing ways to trap carbon dioxide beneath the Earth’s surface. The process, known as carbon sequestration, involves injecting carbon dioxide deep underground. Over time, the gas reacts with the surrounding rock and water and becomes rock itself.


Understanding how bacteria detoxify and eat antibiotics might help us develop ways to address antibiotic contamination in the environment.
Michael Worful

Ten years ago, Gautam Dantas stumbled across a strange phenomenon in the lab: bacteria that were able to feed on antibiotics.

“The story really starts very serendipitously,” said Dantas, who is now a professor of pathology and immunology at Washington University. “Like whoa, there are bugs in the soil that are munching on antibiotics.”

Scientists at Washington University in St. Louis reached a new milestone in cancer research this month with the completion of a comprehensive analysis of the molecular underpinnings of the causes of the disease.

The National Institutes of Health funded the PanCancer Atlas project, more than a decade in the making. Biologists from more than two dozen institutions analyzed DNA from 11,000 cancer patients with 33 major types of the disease, including breast and pancreatic cancer.

The analysis is part of a larger NIH initiative called the Cancer Genome Atlas.

President Donald Trump's proposal to cut the National Institutes of Health 2018 budget by more than a fifth could severely hamper the ability to deliver life-saving treatments to patients, according to a report by Washington University researchers.

In a study published Thursday in the journal Cell Chemical Biology, researchers looked at 100 of the most prescribed drugs and drugs approved by the Food and Drug Administration in the last decade. The NIH funded 93 percent of the 100 widely prescribed drugs and 97 percent of drugs approved between 2010 and 2016.

St. Louis researchers have used a strain of the Zika virus to shrink highly lethal brain tumors in mice. 

The study, run by Washington University and the University of California San Diego, used 33 lab mice with glioblastoma, an aggressive form of brain cancer. Mice injected with a strain of the Zika virus lived longer and were measured to have smaller tumors than the control group, which was injected with saltwater.

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.’”

Washington University psychiatrist Dr. Anne Glowinski discussed the rising prevalence of teen depression on "St. Louis on the Air."

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.

An adult female chimpanzee arrives at a termite nest with two fishing probes. She transfers one fishing tool to her offspring, who uses it to fish for termites, while keeping the other tool for her own use.

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.
