Black Americans experience an increase in poor mental health days during weeks when two or more incidents of anti-Black violence occur and when national interest surrounding the events is higher, according to a new study.
The Andes Mountains of South America are the most species-rich biodiversity hotspot for plant and vertebrate species in the world. But the forest that climbs up this mountain range provides another important service to humanity. Andean forests are helping to protect the planet by acting as a carbon sink, absorbing carbon dioxide and keeping some of this climate-altering gas out of circulation, according to new research published in Nature Communications.
The national Ocular Hypertension Treatment Study was designed to determine whether lowering elevated eye pressure in patients might prevent vision loss from glaucoma. Researchers recently completed follow-up studies on patients 20 years after the start of the original study and found that not all patients with elevated eye pressure need pressure-lowering treatment to prevent vision loss from glaucoma.
Most African American women described successfully navigating the challenges of a breast cancer diagnosis with their partners, finds a new analysis from the Brown School at Washington University in St. Louis.
New research from the Center for Social Development at Washington University’s Brown School shows that parents of newborns with Child Development Accounts (CDAs) respond by deepening their commitment to the child’s higher education and their own efforts to save for that education.
Whatever ultimately caused inhabitants to abandon Cahokia, it was not because they cut down too many trees, according to new research from Washington University in St. Louis.

Children hospitalized with breathing problems due to infection with respiratory syncytial virus (RSV) are likely to get sicker and remain hospitalized if they have high levels of defective copies of the virus, according to a new study by researchers at Washington University School of Medicine in St. Louis.
An aggressive type of brain cancer, glioblastoma has no cure. Patients survive an average of 15 months after diagnosis, with fewer than 10% of patients surviving longer than five years. While researchers are investigating potential new therapies via ongoing clinical trials, a new study from Washington University in St. Louis suggests that a minor adjustment to the current standard treatment — giving chemotherapy in the morning rather than the evening — could add a few months to patients’ survival.
High cholesterol is the most commonly understood cause of atherosclerosis, a hardening of the arteries that raises the risk of heart attack and stroke. But now, scientists at Washington University School of Medicine in St. Louis have identified a gene that likely plays a causal role in coronary artery disease independent of cholesterol levels. The gene also likely has roles in related cardiovascular diseases, including high blood pressure and diabetes.
In one Madagascar forest, the trees teem with lemurs. In another forest just 150 miles away, the last few individuals of a small local population may soon be lost. Scientists are joining up to figure out how to best support these two endangered species.
Researchers at Washington University in St. Louis reported the first observations of a new form of fluorine, the isotope 13F, described March 30 in the journal Physical Review Letters. They made their discovery as part of an experiment conducted at the National Superconducting Cyclotron Laboratory at Michigan State University (MSU).
Climate change is altering the world we share with all living things. But it's surprisingly difficult to single out climate change as an extinction threat for any one particular species protected under the Endangered Species Act. To date, the U.S. Fish and Wildlife Service has only formally considered impacts from climate change in listing actions for four animal species and one alpine tree.
After a long pandemic winter, people are eager to welcome the first cheerful blooms of spring. Lucky for them, many flowers really are popping open earlier in the year. Not so lucky for some plants, though. Plants that rely on bees or other insect pollinators to transport pollen between like individuals — buzzing from violet to violet, or trillium to trillium — face uncertainties when spring becomes front-loaded.
Rectal cancer, along with colon cancer, is the third-most common type of cancer in the United States, and treatment and surgery greatly affect the quality of life of patients. A multi-disciplinary team at Washington University in St. Louis has developed and tested an innovative imaging technique that is able to differentiate between rectal tissues with residual cancers and those without tumors after chemotherapy and radiation, which could one day help to avoid unnecessary surgeries in some patients who have achieved complete tumor destruction after chemoradiation.
Public participation is critical to the success of medical research. Yet recruiting volunteers for trials is increasingly challenging. New Washington University research suggests the widening ideological gap in the U.S. may be to blame.
On March 16, a man went on a shooting rampage at three Atlanta spas, killing eight people, including six Asian women. The killings have sparked outrage and fear in the Asian American community, but the suspect has denied that the killings were racially motivated.The suspect’s claims and subsequent claims made by the Cherokee County Sheriff’s Office have set off a debate about anti-Asian racism in America.
Wearing masks, social distancing and frequent hand-washing have kept in-school COVID-19 transmission low, according to results of a pilot study in Missouri aimed at identifying ways to keep elementary and secondary schools open and safe during the pandemic. The study is part of a larger, ongoing collaboration involving Washington University School of Medicine in St. Louis, the Centers for Disease Control and Prevention, and other groups.
Imposing term limits on justices who sit on the U.S. Supreme Court could bring significant changes to the nation’s highest court, suggests a forthcoming paper from two Washington University in St. Louis law professors.
A foodborne fungus that is harmless to most people exacerbates gastrointestinal symptoms in people with Crohn’s disease by preventing intestinal ulcers from healing, according to a new study from Washington University School of Medicine in St. Louis and the Cleveland Clinic. The findings suggest that antifungal medications or dietary interventions may help alleviate the symptoms of Crohn’s.
Your pay depends on your productivity and occupation. If you earn roughly the same as others in your job, with the precise level determined by your performance, then you're paid market value. And who can question something as objective and impersonal as the market? That, at least, is how many of us tend to think. But, we need to think again, according Jake Rosenfeld, associate professor of sociology at Washington University in St. Louis.
Anniversaries are an opportunity to recognize important events in our lives — both good and bad — and reflect on how they have shaped us. There will be no shortage of anniversaries this month.There are the big anniversaries, like the March 11 anniversary of the World Health Organization declaring the global COVID-19 pandemic.
A new study from Washington University School of Medicine in St. Louis shows that whole genome sequencing is at least as accurate and often better than conventional genetic tests that help determine the treatment for a patient’s blood cancer. Genome sequencing technology continuously is decreasing in cost and recently reached a level similar to that of conventional testing.
The pandemic is exacerbating preexisting social and economic inequalities in the United States and abroad, finds a new study from the Social Policy Institute (SPI) at Washington University in St. Louis.
Power and in-situ resources are two things humans will need as they explore deep space. How future astronauts use these commodities depends on the technology at hand. That’s why NASA is looking to U.S. universities — including Washington University in St. Louis — for lunar-focused research to bring about advancements in in-situ resource utilization and sustainable power solutions.
Scientists at Washington University School of Medicine in St. Louis have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).
New research from Washington University School of Medicine in St. Louis has found that new variants of the virus that causes COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic, potentially undermining the effectiveness of vaccines and antibody-based drugs now being used to prevent or treat COVID-19.
A new study from Washington University School of Medicine in St. Louis and the National Cancer Institute finds a possible link between slow walking pace and an increased risk of death among cancer survivors. The researchers say more work is needed to see if physical activity programs or other interventions could help cancer survivors improve their ability to walk and perhaps increase survival after a cancer diagnosis.
The drug buprenorphine is an effective treatment for opioid use disorder, but many who misuse opioids also take benzodiazepines — drugs that treat anxiety and similar conditions. Many treatment centers hesitate to treat patients addicted to opioids who also take benzodiazepines. Researchers at Washington University School of Medicine in St. Louis studied overdose risk in people taking buprenorphine and found that the drug lowered risk, even in people taking benzodiazepines.
A new study from Washington University School of Medicine in St. Louis provides evidence that COVID-19 patients’ heart damage is caused by the virus invading and replicating inside heart muscle cells, leading to cell death and interfering with heart muscle contraction. The researchers used stem cells to engineer heart tissue that models the human infection and could help in studying the disease and developing possible therapies.
Decades of feminist gains in the workforce have been undermined by the COVID-19 pandemic, which has upended public education across the United States, a critical infrastructure of care that parents - especially mothers - depend on to work, according to new research from Washington University in St. Louis.
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study in Science Advances raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.
Instead of a collapse amid dry conditions, development of agriculture and increasingly complex human social structures set the stage for a dramatic increase in human population in central plains of China around 3,900 to 3,500 years ago.
A new study from Washington University School of Medicine in St. Louis has uncovered a previously unknown role for exosomes in inflammatory respiratory diseases. The study has implications for finding new therapies. Exosomes are tiny compartments released from cells that carry different types of cargo, including inflammatory chemicals called cytokines that can drive lung disease.
Amyloid deposits in the brain increase the risk of dementia and strokes. Researchers at Washington University School of Medicine in St. Louis have identified an antibody that clears amyloid deposits from the brain without raising the risk of brain bleeds.
Antibody-based drugs have been authorized for emergency use in COVID-19 patients by the Food and Drug Administration. Researchers at Washington University School of Medicine in St. Louis have discovered that the ability to interact with other elements of the immune system is an indispensable part of the effectiveness of such antibodies. The findings could help improve the design of the next generation of antibody-based COVID-19 drugs.
New research is exposing how — with little oversight or accountability — lenders prioritized PPP loan applications from businesses with prior lending relationships or personal connections to bank executives in the early stages of the program.
What if the idealized image of American society — a land of opportunity that will reward hard work with economic success — is completely wrong?“Poorly Understood: What America Gets Wrong About Poverty,” a new book from Mark Rank, a leading academic expert on poverty, explores this concept.It is the first book to systematically address and confront many of the most widespread myths pertaining to poverty.
Biologists at Washington University in St. Louis lead a team awarded $1.7 million from the National Science Foundation to streamline the genome of a cyanobacterium with the goal of developing a green cellular factory for sustainable production of food, feed and fuels.
Hydraulic fracturing, also known as “fracking,” relies on water, sand and other chemicals to clear the way for engineers to remove oil or gas from shale — porous rocks below the ground.Engineers know what they are pumping into the ground, but they haven’t understood why they have found certain highly dangerous compounds in flowback — the mixture of water, salt and other chemicals that flows back to the surface after being pumped through the shale.
A new study from Washington University School of Medicine in St. Louis demonstrates that a liquid biopsy examining blood or urine can help gauge the effectiveness of therapy for colorectal cancer that has just begun to spread beyond the original tumor. Such a biopsy can detect lingering disease and could serve as a guide for deciding whether a patient should undergo further treatments.
A new study led by Washington University School of Medicine in St. Louis has revealed a detailed map of the genes, proteins, infiltrating cells and signaling pathways that play key roles in driving glioblastoma. The study, of 99 tumors from patients, is the largest and most detailed schematic of this deadly brain tumor.
Sen. Mitt Romney (R-Utah) has proposed providing at least $3,000 per child to millions of American families. The move could actually provide enormous future savings for the country, says one of the country’s foremost experts on poverty.
It has been more than half a century since the landmark Equal Pay Act passed, yet the gender pay gap still exists. On average, women make 18% less than their male counterparts. Lack of transparency in pay contributes to the disparity, according to a Washington University in St. Louis sociologist.
A new round of COVID-19 relief payments is likely. These relief payments, which propose distributing $1,400 to qualifying adults, will be the third such payment offered since the beginning of the pandemic—the first round of payments occurred in the summer of 2020 offering up to $1,200 per adult and the second round of payments were distributed in the winter offering $600.
Researchers at Washington University School of Medicine in St. Louis have identified a potential way to eradicate the latent HIV infection that lies dormant inside infected immune cells. Studying human immune cells, the researchers showed that such cells have a natural alarm system that detects the activity of a specific HIV protein. Rather than attack the virus based on appearance, this strategy is to attack the virus based on what it is doing — vital activities that are required for the virus to exist.
