In the debate over refugees, immigration, and terrorism, the impact of policy on the practice of science and its role in American prosperity is being ignored.
In an interesting article in the magazine Nautilus, J.B. MacKinnon, reports that a brain scan (fMRI) of free solo climber, Alex Honnold’s brain explains why he is so willing to risk his life to climb rocks without a rope. The fear circuitry in his brain is dysfunctional.
We are on the brink of a new understanding of the neuroscience of violence. Like detectives slipping a fiber optic camera under a door, neuroscientists insert a fiber optic microcamera into the brain of an experimental animal and watch the neural circuits of rage respond during violent behavior.

The Zika virus is a global health threat. Despite renewed urgency because of the evidence suggesting that Zika causes birth defects, science has known of the virus for some time. It’s a deadly and debilitating virus for some newborns, so it’s important to have an accurate picture of the science behind it, the risks of infection and how it affects developing brains.

A neuroscience demonstration.
At the east end of the University of Arizona’s 7.5 acre grass mall is a Carolina sphinx moth fit snug in a blue plastic tube with its insect head sticking out. Two electrodes, one placed on the left eye and the other in a tiny clear plastic tube surrounding the moth’s right antenna. The electrodes are hooked up to a portable screen that displays the measured electrical activity of the moth’s antenna. Each antenna houses a quarter million primary sensory neurons that allow the moth to sense its environment. In this case, the environment happens to be engulfed in the smoky smell of barbecued ribs coming from the BrushFire’s BBQ co. tent next door. Continue reading
Tennis star Maria Sharapova has admitted to using the performance-enhancing drug meldonium, which boosts brain and body power and endurance. Here’s how it works.
