A new study by researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care system shows that people who have been infected with COVID-19 are at an increased risk of developing a range of gastrointestinal conditions within the first month to a year after illness.
Most studies on the effects of heavy metals on bacteria living in these environments have only focused on one metal at a time. In this study, researchers found that exposing bacteria to a mixture of metals caused their metabolism to change and led them to act as if they were starved for iron.
Fluctuating impulsivity in college students is linked to increased positive thoughts about alcohol, heavier drinking, and more negative consequences, a new study suggests—information that could inform more effective intervention programs to reduce alcohol harm. Almost a third of young adults report binge drinking in the past month, and 16% meet criteria for alcohol use disorder in the past year. Impulsivity, a tendency to act rashly without considering consequences, is known to be associated with heavier drinking. A predictive behavioral model theorizes that impulsive people are particularly predisposed to certain beliefs about alcohol and that this influences their consumption. These beliefs—alcohol expectancies—determine how individuals perceive the positive and negative effects of drinking. Positive expectancies (e.g., increased sociability) are linked to higher alcohol use, while negative expectancies (e.g., becoming impaired) are thought to restrain drinking behavior. Recent resea
The 18-foot-long structures, including fascinating honeycomb-shaped tubes, are part of an effort by University of Miami researchers and scientists to help restore damaged coral reefs and protect coastal environments.
Psychiatry researchers at Washington University School of Medicine in St. Louis, led a multicenter study that found, in older adults with treatment-resistant depression, that augmenting an antidepressant drug with aripiprazole helped a significant number of patients.
Now, in a surprising new discovery, Harvard Medical School researchers have found that a class of regulatory T cells (Tregs) made in the gut play a role in repairing injured muscles and mending damaged livers.
In an even more unexpected twist, the researchers found that gut microbes fuel the production of Tregs, which act as immune healers that go on patrol around the body and respond to distress signals from distant sites of injury.
Research led by Washington University School of Medicine in St. Louis has identified a possible treatment strategy for a rare bone marrow failure syndrome that is named poikiloderma with neutropenia. The work also may have implications for treating other bone marrow failure syndromes with similar underlying dysfunctions.

Midwestern agriculture contributes the vast majority of nitrogen in the Gulf of Mexico, causing an oxygen-starved hypoxic zone and challenging coastal economies. State and federal policies have tried for decades to provide solutions and incentives, but the hypoxic zone keeps coming back.
A time-lapse movie from the Hubble Space Telescope captures the impact of asteroid Dimorphos when it was deliberately hit by NASA's DART spacecraft on Sept. 26, 2022. The movie shows three overlapping stages of the impact aftermath: the formation of an ejecta cone; the spiral swirl of debris caught up along the asteroid's orbit about its companion asteroid; and the tail swept behind the asteroid by the pressure of sunlight. Later on, Hubble records the tail splitting in two.

Today, the WORLD Policy Analysis Center (WORLD) at UCLA, launched “Equality within Our Lifetimes,” the most comprehensive analysis to date of laws and policies related to gender equality in all 193 U.N. member states. While the U.S. performs well in some areas, it has become even more of an outlier when it comes to care.
UT Southwestern biochemist Zhijian “James” Chen, Ph.D., famously identified the cGAS enzyme pathway that alerts the human immune system to disease-causing invaders like viruses. Since then, researchers have found that cGAS signaling is an ancient, conserved defense strategy stretching from bacteria to mammals. A new study from the Chen lab published in Nature reports a novel mechanism bacteria use to enhance the effectiveness of the cGAS-mediated immune response.

Previous research estimated that it took hundreds of million years for the ancient Earth's magma ocean to solidify, but new research from Florida State University published in Nature Communications narrows these large uncertainties down to less than just a couple of million years.
Face blindness, a mystifying condition that can trick us into believing we recognize people we’ve never met or make us fail to recognize those we have, has been previously estimated to affect between 2 and 2.5 percent of people in the world.
Now, a new study by researchers at Harvard Medical School (HMS) and the VA Boston Healthcare System is providing fresh insights into the disorder, suggesting it may be more common than currently believed.
New research shows that a warming world is increasing human-wildlife conflicts globally: Climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.
Argonne is focused on building a more diverse workforce in high performance computing (HPC). Sustainable Research Pathways for HPC, an internship & mentoring program, connects students from underrepresented groups with scientists to jump start careers.
Physicists report new evidence that production of an exotic state of matter in collisions of gold nuclei at the Relativistic Heavy Ion Collider (RHIC) can be 'turned off' by lowering the collision energy. The findings will help physicists map out the conditions of temperature and density under which the exotic matter, known as a quark-gluon plasma (QGP), can exist and identify key features of the phases of nuclear matter.
Most voters in Northern Ireland do not rank the Protocol among their highest policy concerns when compared to other policy issues, a new report by researchers at Queen’s University Belfast, has found.

For men undergoing surgery to repair scarring in the urethra (urethroplasty), a new approach to pain management can reduce the need for strong opioid drugs without compromising pain control, reports a study in Urology Practice®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
In Journal of Applied Physics, a team of scientists fabricate sensitive nanostructured silver surfaces to detect arsenic, even at very low concentrations. The sensors make use of surface-enhanced Raman spectroscopy: As a molecule containing arsenic adheres to the surface, it's hit with a laser and the arsenic compound scatters the laser light, creating an identifiable signature. The technique is a departure from existing methods, which are time-consuming, expensive, and not ideally suited to on-site field assays.
Prazosin, a medication FDA-approved for hypertension and used off-label for alcohol use disorder, may help prevent drinking relapse in people with cardiovascular or behavioral symptoms of alcohol withdrawal, according to a new study involving active-duty soldiers.
While no cancer is 100% preventable, a healthful eating plan and regular physical activity can help reduce your risk of developing cancer, according to the Academy of Nutrition and Dietetics.
