Scientists have known about a particular organelle in plant cells for over a century. However, UC Riverside scientists have only now discovered that organelle’s key role in aging. The researchers initially set out to understand more generally which parts of plant cells control plant responses to stress from things like infections, too much salt, or too little light. Serendipitously, they found this organelle, and a protein responsible for maintaining the organelle, control whether plants survive being left too often in the dark.   Because they had not expected this discovery, which is ...

If you hate the rain, you have something in common with wolf spiders. Researchers at the University of Cincinnati found that wolf spiders can’t signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains. The study was published in the Journal of Insect Behavior. Biologists in UC’s College of Arts and Sciences studied Schizocosa ocreata, a wolf spider found across much of the United States. Males respond to chemical signals from females by using a combination of visual ...

Leesburg, VA, January 17, 2024—According to the American Journal of Roentgenology (AJR), the No Surprises Act’s (NSA) independent dispute resolution (IDR) process would be financially unfeasible for a large portion of out-of-network (OON) claims for hospital-based specialties—more so for radiologists than other specialists. “Although the NSA enacted important patient protections, IDR fees limit clinicians’ opportunities to dispute payer-determined payments and potentially undermine their bargaining power in contract negotiations,” ...

Bacterial infections can lead to the formation of abscesses — pockets of dead cells and debris surrounded by inflammatory immune cells. Bacteria multiply within abscesses, causing more inflammation and further damage to surrounding tissues. In severe cases, these immune reactions spread across the body, resulting in life-threatening organ failure, or sepsis. But how these abscesses form and what can be done to prevent them were previously not well understood. Using preclinical models, investigators from Brigham and ...

RIVERSIDE, Calif. -- After COVID vaccination, it usually takes weeks for our bodies to develop protective antibody responses. Imagine, however, a vaccine that speeds up the production of antibodies against SARS-CoV-2, the virus that spreads COVID-19. A research team led by Rong Hai, an associate professor of microbiology and plant pathology at the University of California, Riverside, has developed such a vaccine by using preexisting immunity to a separate virus (the influenza virus) to help kickstart the process of making antibodies ...

MINNEAPOLIS – Approximately 23% of people diagnosed with Alzheimer’s disease or another related dementia in their 60s and later have cases that can be explained by controllable risk factors such as high blood pressure, diabetes, physical inactivity, and too little or too much sleep, and that percentage varies depending on race and ethnicity, according to a new study published in the January 17, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. When including APOE ε4, a gene variant associated with the strongest genetic risk for late-age Alzheimer’s disease, the study found about a third of cases could be explained ...

MINNEAPOLIS – Migraine can impact many aspects of a person’s life, but less is known about how feelings of stigma about the disease affect quality of life. For people with migraine, these feelings of stigma were linked to more disability, increased disease burden and reduced quality of life, according to new research published in the January 17, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Stigma is common where the disease is not readily apparent to others, and there is indication that it could be especially relevant for those living with migraine,” said study author Robert Evan Shapiro, ...

WHAT: Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies—a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys—target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells. The study, published in Science Translational Medicine, was led by the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.  Antibodies ...

In a study of nearly 5,000 North American first-year college students, those who were more extraverted, more agreeable, or less neurotic were more likely to feel a greater sense of belonging at school. Alexandria Stubblebine, an independent researcher in Ocala, Florida, USA, and colleagues present these findings in the open-access journal PLOS ONE on January 17, 2024. Prior research has suggested that one’s personality traits are associated with one’s general sense of belonging. Within a college-specific context, other research has linked a secure sense of belonging to many positives, such as better academic performance and better mental health. Some studies have investigated ...

When it comes to trends in mortality over the last thirty years, countries around the world can be grouped into five clusters, roughly representing the five continents, according to a new study published January 17, 2024, in the open-access journal PLOS ONE by David Atance of Universidad de Alcalá, Spain, and colleagues. While the clusters follow different trajectories, they share some commonalities, including longer life expectancies and fewer disparities between genders and groups of countries with different mortality and longevity indicators. Most countries in the world have seen improvements in longevity over the last two centuries, ...

A study of more than 25,000 U.S. dogs and 238 breeds has linked dog size to varying patterns of risk for health conditions over the course of a dog’s lifespan. Yunbi Nam of the University of Washington, U.S., and colleagues present these findings in the open-access journal PLOS ONE on January 17. On average, smaller dogs tend to live longer than larger dogs. Evidence suggests that larger dogs do not tend to have more health conditions, but that dogs of different sizes may face different levels of risk for different conditions. However, more research is needed to clarify links between dog age, size, and disease prevalence. To deepen understanding, ...
