A surgeon wielding a micro-scalpel cuts through the head capsule of her subject, the nocturnal sweat bee Megalopta genalis, in a lab at the Smithsonian Tropical Research Institute in Panama. The surgeon, a researcher working under Dr. Eric Warrant, of Lund University in Sweden, inserts a glass electrode thinner than a micrometer into the bee’s brain. She is trying to pierce something very small—a monopolar cell in a layer at the top of the brain called the lamina. Warrant believes these cells are responsible for a trick called neural summation, which helps the bees maximize the use of light photons to see in their dark habitat—the dense tangled undergrowth of the nighttime Panamanian rainforest. “It seems that these bees are able to do something that almost defies physics,” says Warrant, (...)
