Sanjeevi Sivasankar was looking for a better tool to study how cells adhere to each other. Cells have surface proteins, called cadherins, that help them stick together. Different kinds of cells have different kinds of cadherins. The typical tools for observing and measuring those...

Ultrasound, a reverberating pitch too high for the human ear to recognize, has many applications including creating images of fetuses in the womb. But Elisa Konofagou, a professor at Columbia University, may be on the brink of uncovering a new use for ultrasound - the ability to temporarily open...

A new system for femtosecond laser-assisted cataract surgery developed at Stanford University School of Medicine uses a new approach to make the procedure less dependent on surgical skill and allow for greater consistency.

Any signal can be decomposed into components of sinusoids. This pioneer technique expands the theory of interchangeability of phase and a shift of time (or a shift of another variable). It faithfully preserves phase information by mathematically rearranging the signal’s...

A microorganism was isolated from the surfaces of the cleanroom facility in which the Phoenix lander was assembled. The isolated bacterial strain was subjected to a comprehensive polyphasic analysis to characterize its taxonomic position. Both phenotypic and phylogenetic analyses...
