Racism Might Be Bad for Your Heart Whether You’re Black Or White

Racism hurts the heart. Both black and white residents of counties where whites reported more racist attitudes were more likely to die from heart disease than those in areas with lower racial bias, according to a recent study from Berkeley psychology researchers. The relationship between whites’ racial bias and death rates was more pronounced for blacks, according to the study, which appeared in the journal Psychological Science last fall.

Strength in Numbers: Inside the Berkeley Institute Where Math Geeks Rule

Ever see the TV game show Let’s Make a Deal? Contestants are given a choice of three doors and told that behind one of them is a shiny new sports car. If they pick door No. 1, the host may open door No. 2 to reveal that there’s nothing behind it. Then he asks if they want to stick with door No. 1 or switch to door No. 3. What’s the best move?

Natural by Design: Next-Gen Robots Run, Flap, Crawl—and Talk to Each Other

Imagine a city in the near future devastated by a powerful earthquake. Rescue workers arrive and unleash hundreds of tiny robots. Some of these robots flap into the air with “wings,” sending images of the disaster area to the ground team—a swarm of insect-like devices the size of a matchbox that scuttle over the concrete and disappear into crevices. One robot’s sensors detect a person trapped under the rubble, so it signals to a larger, stronger robot for assistance before moving on to the next building.
