Endless days… Time… Infinity… Zero…
A Duke University researcher has a new explanation for why those endless days of childhood seemed to last so much longer than they do now - physics. According to Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke, this apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are…

Killing humans. By analyzing rocks. [Brake that rock!]
University of California, Berkeley neuroscientists have tracked the progress of a thought through the brain, showing clearly how the prefrontal cortex at the front of the brain coordinates activity to help us act in response to a perception. Recording the electrical activity of neurons directly from the surface of the brain, the scientists found that…

Remembering. Electricity. Not asking the right questions.
Direct electrical stimulation of the human amygdala, a region of the brain known to regulate memory and emotional behaviors, can enhance next-day recognition of images when applied immediately after the images are viewed, neuroscientists have found. The results were published in PNAS. The findings are the first example of electrical brain stimulation in humans giving…
