Inspired by the work of 18th Century botanist Karl Linne, who assembled a literal circadian clock composed of flower species that open and close their petals at specific times of day, Japanese scientists recently set about constructing an analogous 'body clock' for mammals.
Singapore precision equipment manufacturer Solves Innovative Technology Pte Ltd, together with A*STAR's Institute of Materials Research and Engineering and Data Storage Institute, has built a machine capable of producing nanometer-size components and in wafer-scale volumes, for a host of applications in consumer electronics such as hard disk media and optical storage media.
The films show atoms being added in a regular pattern at the growing tip of a nanotube, like bricks to a round tower, support the so-called theoretical screw-dislocation-like model of carbon nanotube growth.
Music, rather than electromechanical valves, can drive experimental samples through a lab-on-a-chip in a new system developed at the University of Michigan. This development could significantly simplify the process of conducting experiments in microfluidic devices.
Measurements with ytterbium-174, an isotope with 70 protons and 104 neutrons, have shown the largest effects of parity violation in an atom ever observed - a hundred times larger than the most precise measurements made so far, with the element cesium.
