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…

Political favoritism can quite literally be seen from space, according to a new study that finds the home regions of leaders become brighter at night after the person comes to power. The findings apply mostly to countries with weak political institutions and limited public education. One prominent example was Zaire (now the Democratic Republic of…

Electricity: Faster than light!
The experiments of Sir Charles Wheatstone showed that the velocity of electricity is about 288,000 miles per second, much greater than the speed of light, which we all consider as the ultimate barrier. [1, 2, 3, 4] However in order to interpret this we must understand what “electricity” is. In fact we do not have…

Hidden Symmetry
Two Rutgers physics professors have proposed an explanation for a new type of order, or symmetry, in an exotic material made with uranium. When cooled to 17.5 degrees above absolute zero or lower, the flow of electricity through this material changes subtly. The material essentially acts like an electronic version of polarized sunglasses, he explains.…
