In a new study, researchers at the Montreal Neurological Institute and Hospital (The Neuro), McGill University have found an important mechanism involved in setting up the vast communications network of connections in the brain.

Known for their wide variety of vibrant plumage, birds have evolved various chemical and physical mechanisms to produce these beautiful colors over millions of years.

For the first time, Whitehead Institute researchers have shown definitively that mutations associated with prion diseases are sufficient to cause a transmissible neurodegenerative disease.

A novel electronic sensor array for more rapid, accurate and cost-efficient testing of DNA for disease diagnosis and biological research has been developed by scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN).

For over a century, scientists have been using electrical stimulation to explore and treat the human brain. The technique has helped identify regions responsible for specific neural functions—for instance, the motor cortex and pleasure center—and has been used to treat a variety of conditions from Parkinson's disease to depression. Yet no one has been able to see what actually happens at the cellular level when the brain is electrically prodded.

In new animal research done by investigators at Wake Forest University School of Medicine, scientists have discovered a treatment effective in mice at blocking the growth and shrinking the size of lung cancer tumors, one of the leading causes of cancer death in the world.
