A new study from University of California San Diego has found that, while a third of Californians use cannabis regularly, there are significant gaps in knowledge around cannabis use and driving. The researchers found that even six years after the legalization of recreational cannabis use, adults in California demonstrate mixed awareness and knowledge of driving-related laws and regulations. The study results, published in BMC Public Health, come from a large-scale survey of cannabis use in California, titled Impact 64, which was funded by the California ...

EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, OCTOBER 22, 2025 Highlights: A new study finds that having both gum disease and cavities is linked to an 86% increased risk of stroke compared to having a healthy mouth. Poor oral health was tied to a 36% higher risk of heart attacks and other cardiovascular events. People with regular dental visits were 81% less likely to have both gum disease and cavities. Researchers say improving oral health could be an important — and often overlooked — way to help reduce stroke risk. MINNEAPOLIS – People with both cavities and gum disease may face a higher risk of ischemic stroke, according to a study ...

EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, OCTOBER 22, 2025. MINNEAPOLIS – Adults with gum disease may be more likely to have signs of damage to the brain’s white matter, called white matter hyperintensities, than people without gum disease, according to a new study published on October 22, 2025, in Neurology® Open Access, an official journal of the American Academy of Neurology. White matter refers to nerve fibers that help different parts of the brain communicate. Damage to this tissue can affect memory, thinking, balance and coordination and has been linked to higher stroke risk. White matter hyperintensities are bright spots that appear on ...

Researchers led by investigators at Mass General Brigham and Massachusetts Institute of Technology have validated an ingestible capsule in preclinical models for the diagnosis of acute mesenteric ischemia, a condition caused by blocked or reduced blood flow to the intestines. The research is published in Science Robotics. Acute mesenteric ischemia accounts for less than 1.5% of emergency department visits for abdominal pain but has a mortality rate of 55%, due in part to how difficult it can be to diagnose the condition early. “Acute mesenteric ischemia is a potentially deadly but often underdiagnosed ...

Study found which abnormal cells talk to each other in harmful ways and perpetuate lung damage Scientists are already exploring therapeutic strategies based on this study’s discoveries Treatments also could help patients with other lung-scarring diseases (COPD, COVID-19, etc.) CHICAGO --- More than 50% of lung-transplant recipients experience a rejection of their new lung within five years of receiving it, yet the reason why this is such a prevalent complication has remained a medical mystery.  Now, a new Northwestern Medicine study has found that, following transplant and in chronic disease states, abnormal cells emerge and “conversations” ...

Very early on in our universe, when it was a seething hot cauldron of energy, particles made of matter and antimatter bubbled into existence in equal proportions. For example, negatively charged electrons were created in the same numbers as their antimatter siblings, positively charged positrons. When the two particles combined, they canceled each other out.  Billions of years later, our world is dominated by matter. Somehow matter "won out" over antimatter, but scientists still do not know how. Now, two of the largest experiments attempting to find answers—projects that focus on subatomic particles called neutrinos—have joined forces.  In a ...

Three copies of chromosome 21 causes Down syndrome (DS), and roughly half of children born each year in the United States with DS—approximately 2,600—also have congenital heart defects (CHDs). What is not known is exactly why the genes on too many copies of chromosome 21 wreak such devastating effects. In a new paper published in the journal Nature, a team of scientists, including first and co-corresponding author  Sanjeev S. Ranade, PhD, assistant professor in the Center for Cardiovascular and Muscular Diseases and Center for Data Science and Artificial Intelligence at Sanford Burnham Prebys, identify a nuclear ...

About The Study: In this cohort study of more than 1,900 patients in randomized clinical trials (RCTs) for advanced epithelial ovarian cancer, Black and Asian patients were underrepresented compared with the general population estimates in the U.S., and Black patients had worse survival outcomes compared with white and Asian patients, despite having similar progression-free survival. Equitable enrollment in clinical trials ensures access to cutting-edge treatments and can lead to outcomes comparable to those of white counterparts. Sustained efforts to improve RCT diversity remain essential to long-term equity in cancer care and survival.  Corresponding ...

About The Study: In this large national cohort, all adverse pregnancy outcomes except small for gestational age were associated with increased risk for atrial fibrillation up to 46 years later. Women with adverse pregnancy outcomes need early preventive actions and long-term clinical follow-up for timely detection and treatment of cardiovascular disorders related to the development of atrial fibrillation.

Ants have evolved an acute sense of smell, which requires each sensory neuron to choose one scent receptor out of hundreds. In a new study published in Nature, researchers at New York University have discovered what ants use to solve this biological puzzle: a self-regulating system in which choosing one gene physically silences all its neighbors. A high-stakes sense of smell Ants communicate via pheromones to hunt, detect outsiders, and determine their role within a colony. Without precise control of olfactory receptors, ant society would unravel. When ants cannot smell, “they stop performing their duties, which leads to anarchy,” explained ...

SAN FRANCISCO—October 22, 2025—Nearly half of all babies born with Down syndrome face congenital heart defects, often involving serious malformations that require surgery in the first months of life. For decades, scientists have known that having an extra copy of chromosome 21—the genetic cause of Down syndrome—was responsible, but they couldn’t pin down which of its hundreds of genes were key for causing the heart problems. Now, scientists at Gladstone Institutes have an answer. In a study published in Nature, the researchers leveraged stem cell science and ...
