A study by researchers at Washington University School of Medicine in St. Louis and the Broad Institute of MIT and Harvard suggests that women who get recurrent urinary tract infections (UTIs) may be caught in a vicious cycle in which antibiotics given to eradicate one infection predispose them to develop another.
Researchers from the Washington University Center for the Study of Itch and Sensory Disorders have identified a specific neuropeptide and a neural circuit that transmit pleasant touch from the skin to the brain. The findings eventually may help scientists better understand and treat disorders characterized by touch avoidance and impaired social development.
If Florida’s action to strip Walt Disney World of its status as a special tax district is indeed retaliatory against the company for its opposition to the state’s “Don’t Say Gay” law, as critics call it, then Florida has plainly violated the First Amendment, said a constitutional law expert at Washington University in St.
Three of four blood tests used to identify people in early stages of Alzheimer’s disease perform differently in Black individuals compared to white individuals, according to a new study from Washington University School of Medicine in St. Louis. Such differences may put Black patients at risk of misdiagnosis.
By scanning the genomes of nearly 6,000 stroke patients, researchers at Washington University School of Medicine in St. Louis identified two genes associated with recovery. Both are involved in regulating neuronal excitability, suggesting that targeting overstimulated neurons may help promote recovery in the pivotal first 24 hours.
Crows and ravens are well known for their black color and the harsh “caw” sound they make. They are intelligent birds that use tools, solve complex abstract problems and speak a volume of words. But what is less well appreciated is how diverse they are. Their diversity is accompanied by their ability to live all over the world in a variety of habitats.
Up to half of older adults may have sleep apnea, a condition in which breathing and sleep are briefly interrupted many times a night.

Researchers at Washington University School of Medicine have found that many people who tested positive for the coronavirus in the early months of the pandemic also experienced peripheral neuropathy — pain, tingling and numbness in the hands and feet — during and following their bouts with COVID-19.
On March 21, President Biden issued an urgent warning to American business leaders to strengthen their companies’ cyber defenses immediately. In recent weeks, experts have been surprised by the lack of full-scale cyberattacks by Russia. But the threat of devastating cyberattacks is still very real and American companies and individuals must remain vigilant, warned Liberty Vittert, professor of practice of data science at Washington University’s Olin Business School.
Shantanu Chakrabartty at the McKelvey School of Engineering proposes a new kind of encryption to protect data in the age of quantum computers.
Biologists have developed a new method to measure the extent to which regional geographic features — including barriers between regions, like mountains or water — affect local rates of speciation, extinction and dispersal for species. As a test case, they successfully used their model to delineate the movement and diversification of neotropical anole lizards.
The United States Senate’s passing of a resolution supporting a war crimes investigation into Russian President Vladimir Putin for his invasion of Ukraine adds to an international call to hold Putin accountable for Russia’s actions.The invasion gives rise to a real concern not only about breaches of international law for which the Russian Federation might be liable, but about liability of individuals for international crimes, said Leila Sadat, the James Carr Professor of International Criminal Law and Special Adviser on Crimes Against Humanity to the International Criminal Court prosecutor.
International business experts John Horn and Patrick Moreton offer their perspectives on the developing situation with China, including challenges facing the country and what impact their actions could have on the Chinese and global economies.
Alzheimer’s disease is the most common and best known of the tauopathies, a set of neurodegenerative brain diseases caused by toxic tangles of the protein tau. A study by researchers at Washington University School of Medicine in St. Louis has shown that targeting astrocytes — an inflammatory cell in the brain — reduces tau-related brain damage and inflammation in mice.

A new study — in mice — from Washington University School of Medicine in St. Louis suggests that blocking a major inflammatory pathway that is activated in pancreatic cancer makes the tumors sensitive to chemotherapy and a type of immunotherapy that prompts the immune system’s T cells to attack the cancer cells. The therapy more than doubled survival in a mouse model of pancreatic cancer.
Scientists from Washington University in St. Louis are helping to recover gases from a container of lunar soil that astronauts collected and sealed under vacuum on the surface of the Moon in 1972. The effort is part of NASA’s Apollo Next Generation Sample Analysis (ANGSA) initiative. Preliminary science results will be discussed during the Lunar and Planetary Science Conference, which will be held in Houston March 7-11.
Digital technologies are beginning to make inroads into agriculture in lower-income countries in Asia, Africa and Latin America. Precision agriculture has the potential to remove farmers from the local circuits of information and create new dependencies on external commercial services, according to WashU expert Glenn Stone.
Studying mice, researchers at Washington University School of Medicine in St. Louis have discovered that roseolovirus can trigger autoimmunity in a previously unknown way: by disrupting the process by which immune cells learn to avoid targeting their own body's cells and tissues.
Researchers in the lab of Peng Bai at the McKelvey School of Engineering have discovered the key to making a stable, safe battery.
The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia.
Antibiotics provide no benefit in preventing future recurrent wheezing in babies hospitalized with respiratory syncytial virus (RSV), according to a new study led by Washington University School of Medicine in St. Louis. And there is some evidence that antibiotics may make wheezing worse.
If President Joe Biden follows through on his promise to nominate a Black woman to replace retiring Supreme Court Justice Stephen Breyer, longer-term change to the court is possible, based on voting patterns of Black female judges versus white male judges, suggests new research from Washington University in St. Louis.The study, “Replacing Justice Breyer,” suggests that in the near term, the court’s center of power is unlikely to shift to the left, given that the list of possible Biden nominees is ideologically close to Breyer.
After months of anticipation, failed negotiations and broken promises, Russia launched a wide-scale military attack on Ukraine on Thursday, Feb. 24.Yet questions remain regarding Vladimir Putin’s motivation. Is he concerned about Western influence in neighboring Ukraine raising security concerns at home? Does he want to take over Ukraine? Is he deflecting attention from Russia’s domestic problems?“Some combination of these is surely part of the answer, but another little-discussed factor is also at work,” James Wertsch wrote in an op-ed published Feb.
