Talk about precision. New measurements of key wavelengths of ultraviolet light — down to a few millionths of a nanometer — are among the most precise ever reported and are improving calibrations of microlithography tools used in making integrated circuits such as those in computer chips.
The dimensions involved are 10,000 times smaller than hydrogen atoms, the smallest of all atoms.
To make the measurements, physicists at the National Institute of Standards and Technology (NIST) used a spectrometer so sophisticated that it is one of only five of its kind in the world, two of which are at NIST. The spectrometer, which separates and detects specific wavelengths of light radiation, provides 10 times better resolution than similar instruments used in calibrations for highly demanding applications such as the Hubble Space Telescope. The work is reported in the February issue of the Journal of the Optical Society of America B.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
