Scientists create possible precursor to life

Science Daily - Mon, 20/10/2014 - 2:50pm
How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not only understand the origin of life -- we can also revolutionize the future of technology.

New antidepressant: Rapid agent restores pleasure-seeking ahead of other antidepressant action

Science Daily - Mon, 20/10/2014 - 2:50pm
A drug being studied as a fast-acting mood-lifter restored pleasure-seeking behavior independent of -- and ahead of -- its other antidepressant effects. Within 40 minutes after a single infusion of ketamine, treatment-resistant depressed bipolar disorder patients experienced a reversal of a key symptom -- loss of interest in pleasurable activities -- which lasted up to 14 days. Brain scans traced the agent's action to boosted activity in areas at the front and deep in the right hemisphere of the brain.

Digital native fallacy: Teachers still know better when it comes to using technology

Science Daily - Mon, 20/10/2014 - 2:49pm
A new study looks at how teachers and students use technology inside and outside the classroom. It turns out that members of today's younger Net Generation aren't more tech savvy than their teachers just because they were born into a world full of computers. In fact, if it weren't for the coaxing and support of their educators, many students would never use their electronic devices for more than playing games or listening to music, say experts.
