How Electricity Could Improve Your Appreciation Of Art

Test subjects were asked to rate paintings before and after receiving a mild amount of current in a portion of their brain. Paintings that depicted realistic scenes earned higher ratings after the zap.

What's the Latest Development?

University of Milan Bicoccia scientist Zaira Cattaneo and her team asked 12 test subjects to view and rate paintings done in different styles. They then used transcranial direct current stimulation on some of the subjects to deliver a small amount of electric current to a portion of the brain involved in emotion processing. On the other subjects, they performed a similar treatment that used no current. When asked to view and rate the paintings again, those who received the current rated certain paintings -- those depicting real-world scenes -- more highly than before. Their ratings didn't change for abstract works.

What's the Big Idea?

It's hard to say exactly what motivates an individual's appreciation for certain types of art, but scientists working in the relatively young field of neuroaesthetics hope to provide some clarification in the future. Commenting on Cattaneo's study -- which was published in Social Cognitive and Affective Neuroscience -- University of Pennsylvania neurologist Anjan Chatterjee says, "The effect of stimulation was subtle, but still pretty remarkable considering the participants were basically just putting a battery on their head."

Surprising Science

While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.

Why we're so self-critical of ourselves after meeting someone new

A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.

Surprising Science

We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.

NASA launches ICESat-2 into orbit to track ice changes in Antarctica and Greenland

Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.

Firing three pairs of laser beams 10,000 times per second, the ICESat-2 satellite will measure how long it takes for faint reflections to bounce back from ground and sea ice, allowing scientists to measure the thickness, elevation and extent of global ice

Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
