(Phys.org)—David Ruffner and David Grier of New York University have developed a technique for using Bessel beams to draw a particle toward a source. In their paper published in Physical Review Letters they describe how ...
(PhysOrg.com) -- Studying chemical modifications in the chromosomes of cells is akin to searching for changes in coiled spaghetti. Scientists at Cornell have figured out how to stretch out tangled strands of DNA from chromosomes, ...

(Phys.org) —Researchers at Oxford Photovoltaics and other companies investigating the use of perovskite—a crystalline organometal—as a replacement for silicon in photovoltaic cells have created prototypes that are approximately ...
(PhysOrg.com) -- David Cox, a scientist in the Quantum Detection group at the National Physical Laboratory in the UK, is an expert in nanofabrication techniques. Recently, using the tools of his trade and a bit of humor, ...
Tomonori Totani, an astrobiologist with the University of Tokyo is proposing that the search for life beyond Earth be expanded to the study of space dust. In his paper published in the journal International Journal of Astrobiology, ...
Some laws are made to be broken, and others are made to be followed. A team of IBM Researchers in collaboration with two Swiss partners are looking to keep one law in particular alive and well for another 15 years: Moore's ...

(PhysOrg.com) -- Carbon nanotubes are at the center of the nanoelectronics research movement, with scientists making great progress toward getting nanotube-based electronic devices into the hands of consumers. But one area ...
A micrometer ( /maɪˈkrɒmɨtər/ US dict: mī·krŏm′·ĭ·tər), sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are often, but not always, in the form of calipers.
Colloquially the word micrometer is often shortened to mike /ˈmaɪk/ (US dict: mīk′).
