Magnetism's subatomic roots: Study of high-tech materials helps explain everyday phenomenon
19:25 03-09-2010; source: www.sciencedaily.com
Theoretical physicists have created a new model that helps define the subatomic origins of ferromagnetism -- the everyday "magnetism" of compass needles and refrigerator magnets. The model was created to explore the inner workings of ferromagnetic compounds that are related to high-temperature superconductors.
Cognitive effects of Parkinson's disease: Automated tasks easier, but task switching difficult

Researchers have found that people with Parkinson's disease can perform automated tasks better than people without the disease, but have significant difficulty switching from easy to hard tasks.
Chemists, engineers achieve world record with high-speed graphene transistors
18:43 03-09-2010; source: www.sciencedaily.com
Researchers have developed a new fabrication process for high-speed graphene transistors using a nanowire as the self-aligned gate. This new technique does not produce any appreciable defects in the graphene during fabrication, so the carrier mobility is retained. Also, by using a self-aligned approach with a nanowire as the gate, the group was able to overcome alignment difficulties previously encountered and fabricate short channel devices with unprecedented performance.

Hair provides proof of the link between chronic stress and heart attack

Researchers have provided the first direct evidence using a biological marker, to show chronic stress plays an important role in heart attacks. The scientists developed a method to measure cortisol levels in hair providing an accurate assessment of stress levels in the months prior to an acute event such as a heart attack.

There's only so much you can do, but if somebody doesn't give you a chance there is nothing you can do.
You can discover what your enemy fears most by observing the means he uses to frighten you.
The great majority of us are required to live a life of constant, systematic duplicity. Your health is bound to be affected if, day after day, you say the opposite of what you feel, if you grovel before what you dislike and rejoice at what bring you nothi
