Extreme ultraviolet lithography accelerates the future
The era of nanoscale computer chips is almost upon us. Recent advances
employ the "at-wavelength"
extreme-ultraviolet interferometer at the Advanced Light Source, arguably
the most accurate wavefront measuring device in the world, now converted
to print test wafers from advanced optics.

A powerful new magnetic plate combines a permanent magnet with ferromagnetic
materials to select DNA samples much faster than standard magnetic microtiter
plates. It
promises advances in gene sequencing, functional genomics, and the study
of proteins.

Nanowires
composed of two different semiconductors that could function as transistors,
light-emitting diodes, biochemical sensors, thermoelectric heat pumps --
or all of the above on the same length of wire -- may hasten the arrival
of silicon chips packed with billions of electronic devices.
