People whose biological age is higher than their chronological age may be more likely to develop dementia than people whose biological age matches or is lower than their chronological age, according to a study published on April 30, 2025, online in Neurology庐, the medical journal of the American Academy of Neurology.
Scientists have discovered that Mn3Si2Te6 changes from an insulator to an electrically conductive metal when exposed to a magnetic field. In Mn3Si2Te6, applying a magnetic field causes a weak metallic state with trapped electrical changes to form in the material. This study examined the processes that cause this behavior.
Here鈥檚 a look at some of the most recent discoveries that are helping to advance more effective and targeted treatment strategies for glioblastoma and other aggressive brain cancers.
In a study, published in JAMA Oncology, researchers at University of Michigan showed that the proportion of patients undergoing prostatectomy for the lowest-risk type of cancer dropped over fivefold between 2010 to 2024. They concluded that efforts to increase active surveillance and improved diagnostic methods have helped more men avoid unnecessary surgery.
An international team of scientists has moved beyond just 鈥渟cratching the surface,鈥� to understand how microplastics move through and impact the global ocean. For the first time, scientists have mapped microplastic distribution from the surface to the deep sea at a global scale 鈥� revealing not only where plastics accumulate, but how they infiltrate critical ocean systems.
Salt Lake City, Utah 鈥� From May 4 - 8,聽more than 8,000 scientists will gather at the Association for Research in Vision and Ophthalmology鈥檚 (ARVO) 2025 Annual Meeting in Salt Lake City, Utah, to share the latest discoveries in eye and vision research. Many studies being presented focus on the retina, the light-sensitive tissue at the back of the eye that captures the images people see and sends signals to the brain so that people can see and understand the world around them.
Salt Lake City, Utah 鈥� Transformative research offering fresh insights and treatment advancements for age-related macular degeneration (AMD), the leading cause of blindness in adults over age 50, will be among the highlights showcased from May 4 - 8 at the Association for Research in Vision and Ophthalmology鈥檚 (ARVO) 2025 Annual Meeting in Salt Lake City, Utah.
Simultaneous bariatric surgery and liver transplant for patients who are severely obese is safe and improves long-term health outcomes, according to a recent Mayo Clinic study. This combined approach offers a needed solution for these patients who are often denied a lifesaving liver transplant due to their weight.
An FDA-designated orphan drug that can target a key vulnerability in lung cancer shows promise in improving the efficacy of radiation treatments in preclinical models, according to a study by UT Southwestern Medical Center researchers. The findings, published in Science Advances, suggest a new way to enhance the response to radiotherapy by inhibiting DNA repair in lung cancer cells.
Traditional methods of studying human gene mutations are often laborious and costly. Now bioengineers at UC San Diego have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.
