Quantum memory 'world record' smashed
A fragile quantum memory state has been held stable at room temperature for a "world record" 39 minutes - overcoming a key barrier to ultrafast computers. "Qubits" of information encoded in a silicon system persisted for almost 100 times longer than ever before. Quantum systems are notoriously fickle to measure and manipulate, but if harnessed could transform computing. The new benchmark was set by an international team led by Mike Thewalt of Simon Fraser University, Canada. "This opens the possibility of truly long-term storage of quantum information at room temperature," said Prof Thewalt, whose achievement is detailed in the journal Science.

The Power of Stories in Personality Psychology
God made man because He loves stories. ~ Elie Wiesel I’ve always loved this quote in part because I’m a sucker for stories. (As a writer I guess that’s a prerequisite, but we’re all storytellers by nature; yes, all of us.) Stories are how we make sense of our lives and the world and how we communicate with others. Stories also are how we make sense of ourselves. According to researcher Dan P.

The brain region that shouldn't be there
Medial wall of brain with posterior cingulate cortex In the Victorian era the map of Africa was blank and the prospect of mapping its interior lured the most adventurous men of the day. If you are of that frame of mind now, I would recommend exploring the dark interior of the brain . The parts of the brain we understand best are on its surface.

What are some examples of online simulations for science labs?
Printable Version Sometimes it is difficult for students with disabilities to participate in experiments and other science lab activities. Online simulations can help these students participate in science exercises with more independence than may be possible in the traditional lab setting. The following list, although not comprehensive, provides examples of available science simulations. Inclusion on the list does not imply endorsement. Learn.Genetics offers three virtual, interactive Biotechniques laboratories, where students can learn and practice basic techniques that molecular biologists use every day in DNA extraction, gel electrophoresis, and DNA microarray analysis.
