Researchers have uncovered why a common and costly dental implant infection often resists antibiotics. Dental implants have helped tens of millions of people regain a full set of stable, functional teeth, something traditional dentures cannot provide. However, between 10% and 20% of implant recipients eventually develop peri-implantitis, a serious infection that damages the jawbone around [...]
PFDA, a PFAS βforever chemical,β can cause craniofacial birth defects by disrupting retinoic acid regulation during fetal development, revealing the first clear molecular mechanism behind the link. Researchers have long linked perfluoroalkyl and polyfluoroalkyl substances (PFAS), often called βforever chemicals,β to serious birth defects. However, scientists have struggled to explain exactly how these pollutants affect [...]
Scientists have uncovered an early brain mechanism that may help explain why people carrying the APOE4 gene face a higher risk of Alzheimerβs disease. For millions of people who carry the APOE4 gene, the strongest known genetic risk factor for Alzheimerβs disease, changes in brain activity may start years before memory problems become noticeable. Researchers [...]
Humans are wired to focus on threats, making constant negative news exhausting. Limiting exposure and focusing on what you can control helps reduce news fatigue. During several recent conversations, people have told me that theyβve stopped checking their phones in the morning. Not because nothing was happening, but because everything was. They described the feeling [...]
A new study shows that tau helps organize and preserve long-term memories, while abnormal tau may contribute to memory problems in Alzheimerβs disease by disrupting memory formation and recall. New research has revealed that tau, a protein closely linked to Alzheimerβs disease, is also essential for creating long-lasting memories. The findings could point to new [...]
A vitamin D-based therapy may help remodel the protective barrier surrounding pancreatic tumors, offering a potential new treatment strategy. Pancreatic cancer is notoriously difficult to treat in part because tumors surround themselves with a dense, protective barrier that blocks drugs and suppresses immune activity. Now, a small clinical trial led by researchers at Dana-Farber Cancer [...]
Google has applied for an experimental mosquito release permit to deploy millions of non-biting southern house mosquitoes that it has infected with the bacterium Wolbachia pipientis, in an effort to reduce mosquito-borne diseases like West Nile virus.
An arthritis drug reduces the amount of RSV in human respiratory cells, but experts say it's too early to say if it will actually treat the common infection.
A closer look at cancer cells with extra chromosomes uncovered surprising traits linked to faster-growing, more dangerous tumors, pointing to potential new indicators of disease severity. Cancer cells are notorious for breaking the rules of biology. One of the most dramatic violations occurs when a cell suddenly doubles its entire genetic library, creating a chromosome-packed [...]
New research indicates that a moderate amount of weekly strength training may be associated with the greatest longevity benefits, especially when paired with regular aerobic exercise. For years, exercise advice has focused heavily on getting enough cardio. But a major new study suggests that what you do with your muscles may be just as important [...]
A widely prescribed class of weight-loss and diabetes medications may be doing more than improving metabolic health. Drugs such as Ozempic and Wegovy have transformed the treatment of obesity and type 2 diabetes, helping millions lose weight and improve metabolic health. But scientists are increasingly uncovering effects that extend far beyond the scale. Research has [...]
