A wearable ultrasound patch regulates heartbeats from outside the chest, eliminating invasive surgery.

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 “forever chemical,” 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 “forever chemicals,” 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 Alzheimer’s disease. For millions of people who carry the APOE4 gene, the strongest known genetic risk factor for Alzheimer’s disease, changes in brain activity may start years before memory problems become noticeable. Researchers [...]

But there's more to the story than those influencer claims.

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 they’ve 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 Alzheimer’s disease by disrupting memory formation and recall. New research has revealed that tau, a protein closely linked to Alzheimer’s 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 [...]
