Study reveals new information about how to prevent chronic inflammation from zombie-like cells that accumulate with age In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way. Certain factors can cause cells to abandon this characteristic and enter a zombie-like state known as senescence where they persist but no longer divide to make new cells. Our bodies can remove…
University of Arizona neuroscientists studying the brains of songbirds have found that aging alters the gene expressions that control the birds’ song. The finding could lead to earlier diagnoses and better treatments for human neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, which are known to hinder vocal production in their early stages. The study, published in the journal Neurobiology of Aging, found that networks of interacting genes, in a region of the bird’s brain involved with singing, dramatically…
A new type of antibody which stimulates the immune system to target cancer cells slows tumor growth, according to new research Antibody treatment which activates the patient’s own immune system against cancer, known as immunotherapy, is increasingly being investigated as an alternative for chemotherapy and radiotherapy. This is because it specifically targets the cancer cells, which reduces the side effects seen with more conventional therapies. Tumours, such as some breast and ovarian cancers, can express the marker HER2. HER2 is…
Study links genetics, vision and neural processing to mating behavior in Heliconius butterflies A simple neural change alters mating preferences in male butterflies, aiding rapid behavioral evolution, Nicholas VanKuren and Nathan Buerkle at the University of Chicago, US, and colleagues, report March 11th in the open-access journal PLOS Biology. Heliconius are a group of tropical butterflies known for their wide variety of wing patterns and colors, which act as a warning to predators. Because wing coloration is crucial for their…
Scripps Research scientists created a stable form of carnosic acid, observing greater memory function and other disease improvements in mice. The herb rosemary has long been linked with memory: “There’s rosemary, that’s for remembrance,” says Ophelia in Shakespeare’s Hamlet. So it is fitting that researchers would study a compound found in rosemary and sage—carnosic acid—for its impact on Alzheimer’s disease. In the disease, which is the leading cause of dementia and the sixth leading cause of death in the US,…
Researchers from Osaka University find that in immune tissues, plasma cells that express certain proteins are more likely to migrate to the bone marrow, where they help create long-lasting antibody responses Vaccine effectiveness relies on creating a strong antibody response that can be reactivated to fight future infections. Now, researchers from Japan report that antibody-producing cells are destined for longevity from the moment they are born. In a recent study published in the Journal of Experimental Medicine, a multi-institutional research…
American Heart Association Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2025 – Oral Presentation 060 Research Highlights: Embargoed until 11 a.m. CT/12 p.m. ET, Sunday March 9, 2025 This news release contains updated information from the researcher that was not in the abstract and will be referenced in the oral presentation. Among postmenopausal women with a history of cancer, taking more daily steps and engaging in moderate-to-vigorous physical activity were both associated with a significantly reduced risk…
Novel study paints more accurate picture of extinct, gigantic shark The megalodon has long been imagined as an enormous great white shark, but new research suggests that perception is all wrong. The study finds the prehistoric hunter had a much longer body—closer in shape to a lemon shark or even a large whale. The study team, which included researchers from University of California, Riverside and across the globe, used a novel approach to estimate the shark’s total body length, moving…
Declining student performance tied to life skills gaps, not just pandemic The impact of the COVID-19 pandemic on student performance is well known, but four years after the pandemic, scores in college classes are not returning to their pre-pandemic levels. A University of Mississippi study might point to an answer. In a study published in a special issue of the Educational Sciences journal, three Ole Miss researchers found that student performance scores started a downward trend following COVID-19. Dozens of…
Researchers at Rice University have uncovered a critical link between rising temperatures and declines in a species’ population, shedding new light on how global warming threatens natural ecosystems. The study, published in Ecology and led by Volker Rudolf, revealed that rising temperatures exacerbate competition within populations, ultimately leading to population crashes at higher temperatures. It offers one of the first clear experimental confirmations that rising temperatures alter the forces that control population dynamics in nature. “Our research provides an essential missing piece in…
Researchers at the University of Gothenburg have discovered that what was previously thought to be a unique seaweed species of bladderwrack for the Baltic Sea is in fact a giant clone of common bladderwrack, perhaps the world’s largest clone overall. The discovery has implications for predicting the future of seaweed in a changing ocean. In the brakish waters of the Baltic Sea, bladderwrack is the dominant seaweed species as it is one of the few seaweed species that can tolerate…
Cardiovascular diseases remain a leading cause of death worldwide, with platelet hyperactivity and subsequent thrombosis playing a pivotal role in these conditions. While intermittent fasting has long been recognized for its metabolic benefits, including improvements in metabolic diseases, weight loss, and even lifespan extension, its effect on platelet activation and thrombosis formation remains less understood. A recent study by Professor Junbo Ge team at Fudan University unveiled a novel mechanism by which intermittent fasting can significantly reduce the risk of…
They include polycystic ovary syndrome, endometriosis, heavy or irregular periods Having one or more common gynaecological disorders, such as endometriosis or heavy or irregular periods, may be linked to a heightened risk of heart disease and conditions that affect blood flow to the brain (cerebrovascular disease), finds a pooled data analysis of the available evidence published online in the journal Heart. Although the quality of the studies included in the analysis was variable, the researchers nevertheless conclude that clinicians and the…
University’s $59 million research spending in 2024 boosted local, state and national economies while supporting student development University of Texas at Arlington research projects contributed $59 million to the national economy in 2024—an increase of 39% from 2023, according to a new report from the Institute for Research on Innovation and Science (IRIS). UTA has invested heavily in research infrastructure, purchasing cutting-edge scientific equipment and technology, such as North Texas’ most advanced gene sequencer and a super-sensitive magnetic resonance imaging machine for the Clinical…
A groundbreaking study led by a team of researchers at the University of Kentucky has revealed a surprising biochemical connection between plant immune responses and human neurological health. A groundbreaking study led by a team of researchers at the University of Kentucky’s Martin-Gatton College of Agriculture, Food and Environment has revealed a surprising biochemical connection between plant immune responses and human neurological health. Researchers have discovered that the metabolic pathways regulating vitamin B6 homeostasis — critical in certain forms of…
EPFL scientists have developed a geometric deep learning method that can create a coherent picture of neuronal population activity during cognitive and motor tasks across experimental subjects and conditions In the parable of the blind men and the elephant, several blind men each describe a different part of an elephant they are touching – a sharp tusk, a flexible trunk, or a broad leg – and disagree about the animal’s true nature. The story illustrates the problem of understanding an…
