Editorial
Wanted: Good Observers
The above quote is a reminder on the wall of Frank H. Andres’ laboratory, where for the past 13 years the researcher has carefully observed and recorded what he sees through the lens of his microscope. Back in February, I wrote in this column about a study, produced by a classroom of young children and their teacher, on the ability of bees to learn to solve puzzles. The children said...

Thin sheets of light image live cells
Using an extremely thin sheet of light, a new type of microscope reveals the 3-D shapes of cellular landmarks in never-before-seen detail. The technique images live cells at high speed, creating movies of biological processes such as cell division. The ruffled membrane of a monkey kidney cell, as observed by Bessel beam plane illumination microscopy. Images courtesy of Eric Betzig, Thomas...

Critters meet cameras
A giant panda in the Chinese wilderness comes upon a camera attached to a tree. Curious, it approaches the instrument and attempts to put it into its mouth. Through the lens remotely, we catch a glimpse of the secret lives of these animals. Motion-triggered “camera traps” are increasingly used by researchers to study wildlife. Their sensors register an animal’s body heat and...
