BERKELEY, CA "” TEAM 0.5, the world's most powerful transmission electron microscope "” capable of producing images with half angstrom resolution (half a ten-billionth of a meter), less than the diameter of a single hydrogen atom "” has been installed at the Department of Energy's National Center for Electron Microscopy (NCEM) at Lawrence Berkeley National Laboratory. "We have beam down the column," announced Uli Dahmen of Berkeley Lab's Materials Sciences Division, who is...

PARIS and WASHINGTON, May 17 /PRNewswire/ -- Mauna Kea Technologies (MKT), a leader in the field of in vivo cellular imaging for biomedical research and clinical practice, today announced that five oral presentations and eight posters on MKT's Cellvizio(R)-GI will be presented at the Digestive Disease Week(R) (DDW) 2007 conference taking place in Washington, D.C., May 19 to 24. Cellvizio(R)-GI is the Company's technology platform for gastrointestinal applications that enables real-time...

By Jeremy Lovell LONDON (Reuters) - A manuscript charting the birth of modern science, lost for more than 200 years, goes on sale on Tuesday with a price tag in excess of one million pounds. Hailed as "science's missing link," the journal of Robert Hooke contains details of experiments he conducted as curator at the Royal Society from 1662 and his correspondence as its secretary from 1677. It was found by chance in a cupboard at a private house in Hampshire by experts from auctioneer...

Arizona -- It'll be a snap to identify gemstones once Robert Downs finishes his library of spectral fingerprints for all the Earth's minerals.Downs is almost halfway there. So far, the associate professor of geosciences at The University of Arizona in Tucson has cataloged about 1,500 of the approximately 4,000 known minerals using a technique called Raman spectroscopy. The effort is known as the RRUFF Project."We're developing a tricorder," Downs said, referring to the instrument...

Researchers at Stanford University have demonstrated a promising, minimally invasive optical technique that can capture micron-scale images from deep in the brains of live subjects. The method, called two-photon microendoscopy, combines a pair of powerful optical and mechanical techniques into one device that fits in the palm of the hand. The results appear in the September 1, 2005 issue of Optics Letters, a journal published by the Optical Society of America.Researchers want to image...

Not only were images of test patterns (lines formed by layers of chromium and silicon in cross-section) sharper than those made with the XM-1's current 25-nanometer-resolution MZP, the new MZP was able to obtain sharp images of lines a mere 15 nanometers apart "” where the older zone plate had seen only a featureless field of gray. "Nanoscience and nanotechnology are everywhere around us "” biology and chemistry are nanoscience by nature "” but we need better analytical tools to...
