Meghan Owings plucks a horseshoe crab out of a tank and bends its helmet-shaped shell in half to reveal a soft white membrane. Owings inserts a needle and draws a bit of blood. “See how blue it is,” she says, holding the syringe up to the light. It really is. The liquid shines cerulean in the tube. Their distinctive blue blood is used to detect dangerous Gram-negative bacteria such as E. coli in injectable drugs such as insulin, implantable medical devices such as knee replacements, and hospital instruments such as scalpels and IVs. Components of this crab blood have a unique and invaluable talent for finding infection, and that has driven up an insatiable demand. Every year the medical testing industry catches a half-million horseshoe crabs to sample their blood.

There’s some evidence that people with a greater degree of openness also have better visual awareness. For example, when focusing on letters moving on a screen, they are more likely to notice a grey square appearing elsewhere on the display.
Now Anna Antinori at the University of Melbourne in Australia and her team are showing that people who score more highly when it comes to the openness trait “see” more possibilities. “They seem to have a more flexible gate for the visual information that breaks through into their consciousness,” Antinori says.
