Stretch graphene, europium titanate – get interesting results

News: Nanotechnology    August 22, 2010
Forgive the pun, but a new way to get unusual behavior from graphene or europium titanate is a stretch. Literally a stretch, as in taking the material (which is produced in sheets) and stretching it. Stretching is a basic physical technique but applied to unusual materials it sometimes produces unexpected results. In this case two [...]

fMRI reveals conscious activity in vegetative brains

Impact: Neuroscience    February 4, 2010
It’s been seen in numerous movie and television dramas – the brain damaged patient, one with no outward sign of consciousness, who actually can hear, see, or think in an almost normal way. The doctors counsel, “Talk to him. It may do some good.” In dramas the patient usually recovers – talks, is grateful. In [...]

A coordinate system in the brain

News: Neuro-memory    January 21, 2010
In 2005 the Norwegians found them in rats. Now, in 2009, they were found in humans. ‘They’ – are location memory cells in the brain. They appear to be specialized neurons that work in some coordinated fashion. It’s something like having a coordinate system hard-wired into the brain, so as you move about the environment, [...]

Nanodiamonds make a good MRI great

News: Nanomedicine    January 15, 2010
Diamonds are among the hardest substances on Earth. Probably because of their hardness, they are impervious to biological materials. Nanodiamonds, diamond particles no bigger than six nanometers (recall that a nanometer is 1 hundred thousandth of the thickness of human hair), can be released in the human bloodstream and are biologically neutral. So why would [...]
