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 ...

A team of researchers, led by the University of Houston, has discovered two new ways of preventing and treating respiratory viruses. In back-to-back papers in Nature Communications, the team - from the lab of Navin Varadarajan, M.D. Anderson Professor of William A. Brookshire Chemical and Biomolecular Engineering - reports the development and validation of NanoSTING, a nasal spray, as a broad-spectrum immune activator for controlling infection against multiple respiratory viruses; and the development of NanoSTING-SN, a pan-coronavirus nasal vaccine, that can protect against infection and disease by all members of the coronavirus family.  NanoSTING ...

A new UBC study has revealed regular seasonal shifts in people’s moral values. The finding has potential implications for politics, law and health—including the timing of elections and court cases, as well as public response to a health crisis. The research published this week in Proceedings of the National Academy of Sciences (PNAS) analyzed survey responses from more than 230,000 people in the U.S. over 10 years and revealed that people’s embrace of certain moral ...

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, ...

In 2023, roughly 60,000 firework shells exploded above Manhattan’s East River as part of Macy’s Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before. This is according to the results of a new study, led by researchers at NYU Langone Health, which measured air quality just before and after the Independence Day event, one of the largest in the United States. Tiny particles of hazardous metals and organic compounds peaked at 3,000 micrograms per cubic meter at an air sampling site ...

A paper out today in Nature Communications reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone.   Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called ‘Hobbits’ of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island’s west by a team co-led by Australian-New Zealand archaeologist Professor Mike Morwood (1950–2013).   Archaeological evidence suggests these diminutive, small-brained humans inhabited Liang Bua ...

**EMBARGOED FOR RELEASE UNTIL AUG. 6 AT 11 A.M. ET** A protein called Meteorin-like (METRNL) in the tumor microenvironment saps energy from T cells, thereby severely limiting their ability to fight cancer, according to new research directed by investigators at the Johns Hopkins University School of Medicine and the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy. Finding ways to block the effects of METRNL signaling on tumor-infiltrating T cells may allow these immune cells to regain the energy necessary to eliminate tumors.     A report about the work was published Aug. 6 in the journal Immunity.  METRNL ...

Everyone wants to live to a ripe old age, but no one wants to be decrepit. Now, University of Connecticut researchers have demonstrated a treatment that could lengthen life—and vigor—up to the very end. Even as human lifespans have lengthened over the past century, most people in old age suffer a serious health decline in the last decade of life. Chronic illnesses such as cancer, diabetes, or cardiovascular disease may begin, followed by frailty. Many interventions can prolong life, but not necessarily good health. And nobody wants to spend the last ...

In materials science, substances are often classified based on defining factors such as their elemental composition or crystalline structure. This classification is crucial for advances in materials discovery, as it allows researchers to identify promising classes of materials and explore new ones with similar functions and properties. A recent Advanced Intelligent Systems study led by Researcher Nobuya Sato and Assistant Professor Akira Takahashi from Tokyo Institute of Technology developed a new machine learning-powered clustering technique. This technique groups similar materials by taking into account both their ...
