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

Scientists found a new way to slow aging inside cells

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 […]
US justice department releases cache of Epstein files
The US Department of Justice has published a limited cache of heavily redacted documents relating to the late child sex offender Jeffrey Epstein, partially fulfilling a congressional order to release the files.
