Researchers demonstrates the potential to enhance the human intellect's existing capacity to learn new skills

It's a case of life imitating art. Much as the sci-fi film "The Matrix" depicted a device capable of enhancing skill acquisition, researchers at HRL Laboratories, LLC in Malibu, California have discovered that low-current electrical brain stimulation can modulate the learning of complex real-world skills.
Dr. Matthew Phillips and his team of investigators from HRL's Information & System Sciences Laboratory used transcranial direct current stimulation (tDCS) in order to improve learning and skill retention. "We measured the brain activity patterns of six commercial and military pilots, and then transmitted these patterns into novice subjects as they learned to pilot an airplane in a realistic flight simulator," he says.
The study, published in the journal Frontiers in Human Neuroscience, found that subjects who received brain stimulation via electrode-embedded head caps improved their piloting abilities. "We measured the average g-force of the plane during the simulated landing and compared it to control subjects who received a mock brain stimulation," says Phillips.
While previous research has demonstrated that tDCS can both help patients more quickly recover from a stroke and boost a healthy person's creativity, HRL's study is one of the first to show that tDCS is effective in accelerating practical learning.
Phillips speculates that the potential to increase learning with brain stimulation may make this form of accelerated learning commonplace. "As we discover more about optimizing, personalizing, and adapting brain stimulation protocols, we'll likely see these technologies become routine in training and classroom environments," he says. "It's possible that brain stimulation could be implemented for classes like drivers' training, SAT prep, and language learning."

When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them? New research shows for the first time that when adults are engaged in joint play together with their infant, their own brains show similar bursts of high-frequency activity.
Many species of mammals have evolved what appear to be paradoxical behaviours towards their young. Like humans, most exhibit nurturing, protective behaviours, and in some circumstances even act as surrogate parents. However, virgin males often engage in infanticide as a strategy to propagate their own genes. How are these conflicting social behaviours controlled?
