Outbreaks of hand, foot and mouth disease (HFMD), which causes fever and rash in young children, typically occur in the summer months. Similarly, historic cases of polio were observed in the summer months in the United States. Both diseases are caused by different species of enteroviruses, a large genus of RNA viruses. However, the drivers of the seasonal patterns of these diseases have remained somewhat unclear. A common set of drivers can explain the timing of outbreaks of both HFMD and polio according a recent study by researchers at Brown University, Princeton University ...

(Memphis, Tenn. – August 6, 2024) To effectively treat a disease or disorder, doctors must first know the root cause. Such is the case for developmental and epileptic encephalopathies (DEEs), whose root causes can be hugely complex and heterogeneous. Scientists at St. Jude Children’s Research Hospital demonstrated the value of DNA methylation patterns for identifying the root cause of DEEs, showing specific gene methylation and genome-wide methylation “episignatures” ...

URBANA, Ill. – Black Americans experience racial discrimination on a regular basis, and it is a cause of chronic and pervasive stress. It is known to contribute to elevated risk for poor mental health outcomes, but most research has focused on individuals. A new study from the University of Illinois Urbana-Champaign looks at the interpersonal effects of discrimination on parents and their adolescent children. “A person’s experiences with racial discrimination are not just their own but may spill over into the ...

URBANA, Ill. -- Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.  A recent study from the University of Illinois Urbana-Champaign and the University of Pretoria in South Africa demonstrates how African conservation managers could create and optimize elephant movement corridors across a seven-country ...

Social media’s rise to popularity between 2010 and 2020 has been strongly correlated with the nationwide freefall in youth mental health that characterized the 2010s. Lawmakers have put increasing pressure on the U.S. government to take social media regulation more seriously, with cases about platforms like Facebook, Instagram and X rising to the Supreme Court level. But despite the ubiquity of social media, scientists at Northwestern Medicine and Ann & Robert H. Lurie Children’s Hospital of Chicago found that in Illinois, youth emergency room visits and hospitalizations for depression and anxiety decreased ...

or many plants, more branches means more fruit. But what causes a plant to grow branches? New research from the University of California, Davis shows how plants break down the hormone strigolactone, which suppresses branching, to become more “bushy.” Understanding how strigolactone is regulated could have big implications for many crop plants. The study was published August 1 in Nature Communications. “Being able to manipulate strigolactone could also have implications beyond plant architecture, including on a plant’s resilience to drought and pathogens,” said senior author Nitzan Shabek, an associate professor in the UC Davis Department of ...

How would you summarize your study for a lay audience? Some proteins, such as programmed cell death protein 1 (PD1), can stop the immune system from attacking cancer cells and, therefore, support the growth of cancer. Therapies targeting these proteins can be highly effective, but tumors can become resistant. We applied a method to detect proteins on a single–cell level to uncover human carcinoembryonic antigen cell adhesion molecule 1 (CEACAM1) patterns in melanoma. We found that increased ...

Using mice with the disease, the researchers found that treatment with dopamine could alleviate physical symptoms in the brain as well as improve memory. Published in the scientific journal Science Signaling on August 6, the study examines dopamine’s role in promoting the production of neprilysin, an enzyme that can break down the harmful plaques in the brain that are the ...

Millions of Americans consume supplements that contain potentially hepatoxic botanical ingredients, according to a study from University of Michigan researchers. Over a 30-day period, 4.7% of the adults surveyed in the National Health and Nutrition Examination Survey conducted from 2017 to 2020 took herbal and dietary supplements containing at least one of the botanicals of interest: turmeric; green tea; ashwagandha; black cohosh; garcinia cambogia; and red yeast rice containing products. The resulting paper, “Estimated Exposure ...

Sometimes you just can’t win, and that goes double for people navigating the increasingly polarized political landscape in the United States. Having nuanced opinions of politics in the U.S. turns out to be a very lonely, and unpopular, road, according to a recent study from a research team that includes assistant professor Aviva Phillipp-Muller from Simon Fraser University’s Beedie School of Business.   Published in the Journal of Experimental Social Psychology, the study found that people who express ambivalence about political topics – ranging from COVID-19 mask mandates, immigration and the death ...

EL PASO, Texas (Aug. 6, 2024) – Grab a drink with friends at happy hour and you’re likely to feel chatty, friendly and upbeat. But grab a drink alone and you may experience feelings of depression. Researchers think they now know why this happens. “Social settings influence how individuals react to alcohol, yet there is no mechanistic study on how and why this occurs,” said Kyung-An Han, Ph.D., a biologist at The University of Texas at El Paso who uses fruit flies to study alcoholism. Now, Han and a team of UTEP faculty and students have taken a key step in understanding the neurobiological process behind social drinking and how it boosts ...

The chemical and energy industries depend upon catalysts to drive the reactions used to create their products. Many important reactions use heterogeneous catalysts — meaning that the catalysts are in a different phase of matter than the substances they are reacting with, such as solid platinum reacting with gases in an automobile’s catalytic converter. Scientists have investigated the surface of well-defined single crystals, illuminating the mechanisms underlying many chemical reactions. However, there is much more to be learned. For heterogeneous catalysts, their 3D atomic structure, their chemical composition and the nature of ...

When we’re sick, the first step on the road to recovery is a visit to the doctor’s office.  It turns out the same may also be true for breathing life into America’s democracy. A Rutgers University–New Brunswick study published in the journal JAMA Health Forum finds that physicians can play a crucial role in strengthening political inclusion of marginalized groups by aiding patients in voter registration. “Hospitals aren’t the first place we think of when it comes to voter registration,” said Katherine McCabe, an associate professor of American politics at Rutgers University-New Brunswick and lead ...

Electronic waste, or e-waste, is a rapidly growing global problem, and it’s expected to worsen with the production of new kinds of flexible electronics for robotics, wearable devices, health monitors, and other new applications, including single-use devices. A new kind of flexible substrate material developed at MIT, the University of Utah, and Meta has the potential to enable not only the recycling of materials and components at the end of a device’s useful life, but also the scalable manufacture of more ...

Working with human stem cells that form a kind of “mini intestine-in-a-dish,” Johns Hopkins Medicine scientists say they have found several molecular mechanisms for COVID-19-related diarrhea, suggesting potential ways to control it. Details of the experiments in a model of human intestinal tissue, called enteroids, are described on July 30 in Cellular and Molecular Gastroenterology and Hepatology. Along with the unpleasant aches, fever, sore throat, cough, respiratory distress and other symptoms that may accompany COVID-19 infection, up to half of people who get the virus will experience diarrhea. Some 30% of them will go on to develop ...

Leuven, 6 August 2024 - A team of researchers from the lab of Prof. Stein Aerts (VIB-KU Leuven) presents Nova-ST, a new spatial transcriptomics technique that promises to transform gene expression profiling in tissue samples. Nova-ST will make large-scale, high-resolution spatial tissue analysis more accessible and affordable, offering significant benefits for researchers. The research was published in Cell Reports Methods. Transcriptomics is the study of gene expression in a cell or a population of cells, but it usually does not include spatial information about where those genes were active. This hurdle limited our understanding of complex ...

BUFFALO, NY- August 6, 2024 – On July 28, 2024, Mikhail V. Blagosklonny M.D., Ph.D., from Roswell Park Comprehensive Cancer Center published a new editorial in Volume 16, Issue 14 of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), entitled, “Targeted cancer therapy: the initial high concentration may slow down the selection for resistance.” “Unfortunately, any targeted therapy is, always, started with low levels of the drug in the organism, selecting for drug resistance. One should propose that initial drug levels must be maximized, ...
