The molecules behind metastasis

Many cancer cells never leave their original tumors. Some cancer cells evolve the ability to migrate to other tissues, but once there cannot manage to form new tumors, and so remain dormant. The deadliest cancer cells are ...

Gene therapy for heart attacks in mice just got more precise

If humans are ever going to be able to regrow damaged tissues the way lizards and fish routinely do, it will require the precise control of gene expression in time and place—otherwise you might end up with random cells ...

Researchers unlock pattern of gene activity for ADHD

Researchers at the National Institutes of Health have successfully identified differences in gene activity in the brains of people with attention deficit hyperactivity disorder (ADHD). The study, led by scientists at the ...

Understanding the minutiae of seeing in 3D

So much has to go right as our visual systems develop. One of them is that many thousands of retinal ganglion cells (RGCs) have to relay signals through the eye's optic nerve via delicate projections, or axons, to precise ...

System that uses light stimulation to modulate brain waves

Researchers have developed a system which uses light stimulation to modulate brain waves. This opens up new avenues to explore for possible treatment of conditions such as epilepsy, Parkinson's and migraine.

New tool reveals what happens in the brain when we learn

Scientists at Scripps Research have developed a new tool to monitor brain plasticity—the way our brains remodel and physically adapt as we learn and experience things, from watching a movie to learning a new song or language. ...
