Virginia Tech scientists at the Fralin Biomedical Research Institute say the increased risk of cardiovascular disease after menopause may be due not only to lower hormone levels, but also to how those changes affect gene activity. In a new paper published in a magazine cellresearchers are looking at growing evidence that lower estrogen levels can alter epigenetics, the system that controls turning genes on and off. These changes may help explain why the incidence of heart disease, diabetes, and other metabolic diseases rises sharply in postmenopausal women. Additionally, this study also revealed a potential link between decreased estrogen, changes in…

Researchers at the University of California, San Diego School of Medicine, the Salk Institute, and Sanford Burnham Prebys have received a four-year, $13 million award from the California Institute for Regenerative Medicine (CIRM) to study ways to reverse age-related neurodegeneration by eliminating what the researchers call the “RNA contamination” of aging neurons. The ultimate goal is to develop new treatments to protect against neurodegenerative diseases. As brain cells age, they make more mistakes when processing genetic instructions (RNA). This creates RNA contamination that can accumulate over decades, stressing cells and making the brain highly vulnerable to diseases such as Alzheimer’s…

A strange object known as a “golden orb” has baffled scientists and gained public attention after it was collected during a 2023 National Oceanic and Atmospheric Administration (NOAA) expedition. More than two years later, researchers have finally determined what it is. Discovered at a depth of 3,250 meters (more than two miles) in the Gulf of Alaska, this unusual golden nugget turned out to be the remains of the dead tissue of a giant deep-sea sea anemone. Relicanthus daphnia. Specifically, it was part of the base that anchors the sea anemone to the rocky surface of the ocean floor. It…

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States and disproportionately impacts those receiving care in low-resource settings. Fortunately, several effective screening tests are available to detect most treatable cancers early. Researchers from Massachusetts General Brigham and UCLA Health, in collaboration with community health centers (CHCs), mailed one of two stool-based screening tests to more than 5,000 participants from CHCs in Boston and Los Angeles. The researchers found that participants were more likely to complete the screening if they received the new stool-based screening test, but the uptake of follow-up colonoscopies for participants with…

A new mathematical model developed by researchers at the University of Bristol could bring us one step closer to understanding how wounds heal after injury. Research published in physical review letter The study builds on previous work in Drosophila in which researchers observed how skin-like epithelial cells move to cover wounds.An important part of wound repair is re-epithelialization. This is a process in which skin cells spread throughout the wound and rebuild the body’s outer protective barrier. When this process is disrupted, the wound remains open and susceptible to infection, so it is important to understand what physical mechanisms and…

Researchers at Cedars-Sinai University of Health Sciences have developed and successfully tested a new treatment for pregnant women with severe early preeclampsia, a leading cause of premature birth and maternal and infant death. Early stage international research published in journals natural medicinefocused on removing harmful proteins from the mother’s blood. Preeclampsia is characterized by high blood pressure and can quickly become life-threatening. In the most severe early forms (before 34 weeks of gestation), doctors often have to deliver prematurely to protect the mother, even though early delivery can pose significant risks to the infant. The method tested by researchers was…

The American Medical Association (AMA) on Thursday urged federal lawmakers to strengthen protections amid the increasing use of artificial intelligence chatbots for mental health. The organization sent a letter to the co-chairs of the Congressional Caucus on Artificial Intelligence (PDF), the Congressional Caucus on Digital Health (PDF), and the Senate Caucus on Artificial Intelligence (PDF). The group praised the efforts of lawmakers to “promote the debate about the role of AI in society and mental health,” but said the rise of mental health chatbots, including reports encouraging self-harm and privacy violations, “highlights the urgent need for clear guardrails.” Safety measures…

Delaying hepatitis B vaccination after birth increases neonatal infections and reduces survival rates and quality of life, according to a new study from Cornell University. The paper, “Economic Evaluation of Delays in Infant Hepatitis B Vaccination Schedules,” is embargoed until April 27, 2026, at 11 a.m. ET. JAMA Pediatrics. The study found that the longer the delay, the higher the cost in lives and health care, with costs ranging from $16 million to $370 million, depending on the age of first vaccination and compliance with the vaccination schedule. Chronic hepatitis B is a leading cause of cirrhosis, liver failure, liver…

New research suggests finding age-appropriate, well-fitting clothing plays a role in midlife women’s overall mental health. This research shows that when women in this demographic are satisfied with their fashion choices, they tend to experience higher levels of happiness and less social avoidance. These research results have recently macromarketing journal. Researchers Jekaterina Rogaten and Viviana Rullo conducted this study to investigate how the modern fashion industry affects middle-aged consumers. The fashion market often prioritizes styles for young people, leaving older women with fewer options to suit their changing body shapes and professional needs. Despite having high purchasing power and often…
