When making visual art during their recovery from traumatic brain injuries (TBI), military service members who depicted psychological injuries like depression or anxiety in their artwork tended to have more acute post-traumatic stress disorder than those who used...

Scientists at Newcastle University have developed a biological system which lets cells form a desired shape by moulding their surrounding material -- in the first instance creating a self-curving cornea. The cornea is the clear outer layer at the...

Every year in Europe, three million people are admitted into hospitals for suspected mild traumatic brain injury (mTBI) cases. Yet 90% of these patients will be able to return home safely, as no trauma has been detected. Today,...

It takes a lot of cells to make a human brain. The organ houses not only an enormous quantity of neurons (tens of billions), but also an impressive diversity of neuron types. In recent years, scientists have been...

Beliefs can be hard to change, even if they are scientifically wrong. But those on the fence about an idea can be swayed after hearing facts related to the misinformation, according to a study led by Princeton University. After...

The tissues in our bodies largely are made of fluid. It moves around cells and is essential to normal body function. But in some cases, this fluid may be doing more harm than good. In people who have glioblastoma, the...

If the cell nucleus is like a bank for DNA, nuclear pores are the security doors around its perimeter. Yet more security doors aren't necessarily better: some cancer cells contain a dramatic excess of nuclear pores. Salk Institute researchers...
