The atomic-force microscope (AFM) was developed 20 years ago, but only recently has it become a significant tool for biologists.

Brian Fisher, curator of entomology at the California Academy of Sciences, has such enthusiasm for ants, he can make you feel guilty over spraying the little devils in your kitchen.

When an oscilloscope's audio monitor starts to screech rhythmically in a neurophysiology lab, its waves hint at one of the most puzzling patterns in biology.

Although arguments remain over whether autism is genuinely on the rise to the astonishing degree reported in places like California, there is general agreement among scientists that the condition has a genetic basis.

Shortly after the invention of the laser, Bell Labs physicist Arthur Ashkin began exploring the range of the new devices.

Three decades and 6,000 papers since the term was first coined, scientists are still debating the mechanisms of long-term potentiation (LTP).1 Defined in 1973 as an increase in synaptic strength following experimentally induced high-frequency stimulation,2 LTP has been consistently controversial. Now at last, "There is a consensus beginning to emerge," says Columbia University Nobel laureate, Eric Kandel, as years of research have begun to make sense of what once seemed irreconcilable contradict

The story goes like this: At a 1976 Biophysical Society meeting, Erwin Neher presented the technique that would win a Nobel Prize for him and Bert Sakmann.

With inquisitive minds and tools as simple as a Waring blender, the work of early phage researchers such as Max Delbruck, Seymour Benzer, and Alfred Hershey generated much of the knowledge underlying contemporary molecular biology.
