Fortifying computer chips for space travel

Space is cold, dark, and lonely. Deadly, too, if any one of a million things goes wrong on your spaceship. It’s certainly no place for a computer chip to fail, which can happen due to the abundance of radiation bombarding a craft. Worse, ever-shrinking components on microprocessors make computers more prone to damage from high-energy radiation like protons from the sun or cosmic rays from beyond our galaxy. —> Read More

Depression Literally Colors The Way We See The World

Our moods can, quite literally, color our world — particularly in the case of depression.

New research published last week in the journal Psychological Science finds that sadness can affect our vision, making the world appear more gray, by impairing the neural processes involved in color perception.

As it turns out, there’s a reason we use colors as a metaphor for emotion, with expressions like “feeling blue” or having a “gray day.”

“It was interesting that we have so many metaphors that link emotion and color perception,” Christopher Thorstenson, a psychology researcher at the University of Rochester and the study’s lead author, told The Huffington Post in an email. “We were curious whether there really was a link between sadness and how people see color.”

To answer this question, the researchers asked 127 undergraduates to watch either a sad or funny video. Then, the students viewed 48 color swatches — which were desaturated to the point of being almost gray — and tried to identify them as red, yellow, green or blue. Those who had watched the sad clip were less accurate in identifying colors than the students who watched the funny clip, suggesting that they were perceiving less of the color.

The findings build on previous research that investigated the link between mood and perception. Other studies found that when people have a goal to reach or an object to attain — such as the finish line of a race — they may perceive that object to be larger than it really is. People experiencing fear, on the other hand, may perceive certain things in their environment — such as faces with negative expressions — as more threatening than they actually are.

This is because our emotions carry information about the value of objects, and that information is incorporated —> Read More
