A hidden T cell switch could make cancer immunotherapy work for more people

Over the past ten years, T cell immunotherapy has emerged as one of the most promising developments in cancer treatment. These therapies work by training a patient’s own immune system to detect and destroy dangerous cells. Despite their success, scientists have struggled to fully explain how these treatments function at a molecular level. This lack […]

The gear meant to protect firefighters may carry hidden dangers

A new study published on Dec. 16 in Environmental Science & Technology Letters reports that some firefighter protective gear contains brominated flame retardants, chemicals that may pose health risks to firefighters. The research is the first U.S. study to formally examine and document the use of brominated flame retardants in firefighter turnout gear, which is […]

Neurons aren’t supposed to regrow but these ones brought back vision

For decades, neuroscientists have taught that neurons do not regenerate once they are damaged or destroyed. This belief has shaped how brain injuries are understood and treated. Yet people often regain at least some lost abilities after trauma, raising an important question: if neurons do not grow back, how does recovery happen? A new JNeurosci […]

Glowing neurons let scientists watch the brain work in real time

About ten years ago, researchers began exploring a bold idea: using bioluminescent light to see what the brain is doing in real time. Instead of shining light onto brain tissue from the outside, they wondered whether neurons could be made to glow on their own. “We started thinking: ‘What if we could light up the […]

Scientists found a new way to slow aging inside cells

People around the world are living longer than ever, and that shift is changing what many want from aging. The goal is no longer just more years, but more good years. That has put new attention on “healthspan,” the stretch of life when someone remains energetic, independent, and generally free of serious age-related problems. A […]

Helping others for a few hours a week may slow brain aging

Strong social ties are often linked to better health, and new research adds a brain benefit to that list. Researchers from The University of Texas at Austin and University of Massachusetts Boston report that regularly helping people outside your household can noticeably slow cognitive decline in middle-age and older adults. In a study that followed […]

An 11-year-old needed two new organs and doctors made history

Children’s Hospital Colorado (Children’s Colorado) has completed its first-ever dual heart and liver transplant, marking a major milestone for the hospital. The complex procedure involved dozens of specialists working across 25 multidisciplinary care teams. Nationwide, only 38 pediatric patients have previously received both a heart and liver transplant. “Performing Children’s Colorado’s first-ever heart and liver […]

The 98% mystery: Scientists just cracked the code on “junk DNA” linked to Alzheimer’s

When people picture DNA, they often imagine a set of genes that shape our physical traits, influence behavior, and help keep our cells and organs functioning. But genes make up only a small slice of our genetic code. Just around 2% of DNA contains our 20,000-odd genes. The other 98% has long been labelled the […]
