Oysters' exposure to plastics is concerning, particularly because these materials can accumulate and release metals which are then absorbed by the molluscs. According to a recent study published in the journal Chemosphere, the combined presence of nanoplastics and arsenic affects the biological functions of oysters.
For the first time, a prospective, international study has shown that chest pain caused by problems with the very small vessels supplying blood to the heart is an important health problem that increases the risk of heart attacks, stroke and death due to cardiovascular reasons.
Research shows that poor sleep health may disproportionately affect children of color from families of low socioeconomic status and place them at risk for behavior problems and lower academic performance. However, few sleep studies utilize standard measures of both classroom behavior and academic achievement.
Highlights
Among patients receiving dialysis in the Southeastern United States, those at for-profit dialysis facilities were less likely to be referred for kidney transplantation than those at non-profit facilities.
Rates of starting medical evaluations soon after referral and placing patients on a waitlist after evaluations were similar between the groups.
Jodi Karnell and colleagues have developed a monoclonal antibody, VIB7734, that reduces symptom severity in people with cutaneous lupus by targeting and depleting plasmacytoid dendritic cells (pDC) in blood and skin. In two phase I clinical trials involving a total of 67 people with autoimmune diseases such as lupus, treatment with VIB7734 was as safe as a placebo and significantly reduced pDC frequencies, the researchers found. The antibody also reduced the activity of a group of key immune proteins called type 1 interferons in skin.
UNIVERSITY PARK, Pa. -- One of the most important and widespread reef-building corals, known as cauliflower coral, exhibits strong partnerships with certain species of symbiotic algae, and these relationships have persisted through periods of intense climate fluctuations over the last 1.5 million years, according to a new study led by researchers at Penn State. The findings suggest that these corals and their symbiotic algae may have the capacity to adjust to modern-day increases in ocean warming, at least over the coming decades.
To help patients manage their mental wellness between appointments, researchers at Texas A&M University have developed a smart device-based electronic platform that can continuously monitor the state of hyperarousal, one of the signs of psychiatric distress. They said this advanced technology could read facial cues, analyze voice patterns and integrate readings from built-in vital signs sensors on smartwatches to determine if a patient is under stress.
Up to half of patients with head and neck squamous cell carcinoma will experience tumor recurrence or new tumors--tumors that often spread and are difficult to treat.
A team of scientists led by the University of Michigan School of Dentistry identified a mechanism by which head and neck cancer cells subvert adjacent normal tissue, allowing small clusters of cancer cells to burrow beneath the healthy tissue.
ITHACA, N.Y. - Approximately one-third of all U.S. counties do not exempt grocery foods from the general sales tax, which means the lowest-income families living in those areas are most susceptible to food insecurity. New research from Cornell University finds that even a slight grocery tax-rate increase could be problematic for many.
It's well known that reptiles depend on temperature cues while in the egg to determine a hatchling's sex. Now, researchers writing in the journal Trends in Ecology & Evolution on May 26 say that embryos of many different animal species also rely on acoustic signals in important ways. They call this phenomenon "acoustic developmental programming."
Skokie, IL - The International Society for Stem Cell Research (ISSCR), today released updated guidelines for stem cell research and its translation to medicine. The update reflects emerging advances including, stem cell-based embryo models, human embryo research, chimeras, organoids, and genome editing.
Communities benefit from sharing knowledge and experience among their members. Following a similar principle - called "swarm learning" - an international research team has trained artificial intelligence algorithms to detect blood cancer, lung diseases and COVID-19 in data stored in a decentralized fashion. This approach has advantage over conventional methods since it inherently provides privacy preservation technologies, which facilitates cross-site analysis of scientific data.
New research published in Nature provides a powerful yet surprisingly simple way to determine the number of visitors to any location in a city.
What The Study Did: Researchers conducted a review of studies examining the frequency and variety of persistent symptoms after COVID-19 infection.

In the human gut, good bacteria make great neighbors.
A new Northwestern University study found that specific types of gut bacteria can protect other good bacteria from cancer treatments -- mitigating harmful, drug-induced changes to the gut microbiome. By metabolizing chemotherapy drugs, the protective bacteria could temper short- and long-term side effects of treatment.
