Polystyrene surface triples number of human ES and iPS cells in culture

By irradiating typical polystyrene lab plates with ultraviolet (UV) waves, Whitehead Institute and MIT scientists have created a surface capable of tripling the number of human embryonic stem (ES) and induced pluripotent stem (iPS) cells that can be grown in culture by current methods. Use of this novel surface also eliminates the need for layers of mouse "feeder cells" to support ES- and iPS-cell growth.

Scientists discover neurons responsible for light-induced arousal response

Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people use masks to make sure light doesn't wake them while they sleep.

First study to show how H. pylori toxin can spur apoptosis

Researchers report they have figured out how the cancer-causing bacterium Helicobacter pylori attacks a cell's energy infrastructure, sparking a series of events in the cell that ultimately lead it to self-destruct.

Peroxiredoxin enzyme holds key to ageing process

By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process.

Oscillatory signals in basal ganglia cause motor deficits in Parkinson's

The research group headed by Professor Atsushi Nambu and Professor Masahiko Takada has shown that the 'oscillatory' nature of electrical signals in subcortical nuclei, the basal ganglia, causes severe motor deficits in Parkinson's disease, by disturbing the information flow of motor commands.
