UCF scientists control living cells with light; advances could enhance stem cells' power
University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. view more (2009-08-12)
Scientists help police bust forgers
Forging wills and bank cheques could now be near impossible thanks to a team of physicists in Rome (Italy). Writing in the latest issue of the Institute of Physics journal, Journal of Optics A, the scientists announce a new technique that can detect forged handwriting better than ever before. Professor Giuseppe Schirripa Spagnolo, Carla... view more... (2004-08-08)
Scientists successfully awaken sleeping stem cells
Scientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells. view more (2008-03-19)
Repel the aphids and you attract the leafhoppers
Things don`t always turn out as you expect when you play with genes AN ATTEMPT to make potato plants resistant to sap-sucking insects has highlighted the unpredictability of genetic engineering. The modified plants unexpectedly turned out to be vulnerable to other kinds of insect pests, demonstrating how important it is to assess each transgenic... view more... (2002-05-29)
On a Wire or in a Fiber, a Wave is a Wave
In an experiment modeled on the classic "Young's double slit experiment" and published in the journal Nature Nanotechnology, researchers have powerfully reinforced the understanding that surface plasmon polaritons (SPPs) propagate and diffract just like any other wave. view more (2007-07-16)
First triple asteroid system found
One of the thousands of asteroids orbiting the sun has been found to have a mini planetary system of its own. view more (2005-08-11)
Declining sharks
The transformation of terrestrial and coastal ecosystems by humans is well known, but only recently have the impacts of anthropogenic forces in the open ocean been recognized. In particular, intense exploitation by industrial fisheries is rapidly changing oceanic ecosystems by drastically reducing populations of many marine species. For most... view more... (2004-02-05)
New technique measures ultrashort laser pulses at focus
Lasers that emit ultrashort pulses of light are used for numerous applications including micromachining, microscopy, laser eye surgery, spectroscopy and controlling chemical reactions. But the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. view more (2008-05-09)
Laser-optical mine detection needle will facilitate mine clearing
The "laser-optical mine detection needle" is intended to facilitate the removal of land mines for humanitarian reasons. The working group of Professor Dr. Wolfgang Schade at the Institute of Physics und Physical Technologies at the Technical University of Clausthal intends to exhibit a "laser-optical mine detection needle" at... view more...

PTB Terahertz calibration satisfies US laser manufacturer
Terahertz radiation still lies in a metrological no man's land - a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. view more (2009-11-06)
Microscopic brain imaging in the palm of your hand
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. view more (2005-08-25)
Iowa State plant scientists tweak their biopharmaceutical corn research project
A biopharmaceutical corn created at Iowa State University is getting a makeover. Researchers are developing the corn into a variety that keeps the therapeutic protein, but eliminates the pollen. And they're using traditional breeding to do it. view more (2006-06-26)
Scientists demonstrate highly directional semiconductor lasers
Applied scientists at Harvard University in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and... view more... (2008-07-28)
Lighter gas reduces damage to optics in extreme ultraviolet lithography
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips. view more (2007-09-13)
Transforming Nanowires Into Nano-Tools Using Cation Exchange Reactions
A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. view more (2009-10-26)
Loss of tumor supressor gene essential to transforming benign nerve tumors into cancers
Researchers at UCLA's Jonsson Comprehensive Cancer Center showed for the first time that the loss or decreased expression of the tumor suppressor gene PTEN plays a central role in the malignant transformation of benign nerve tumors called neurofibromas into a malignant and extremely deadly form of sarcoma. view more (2009-10-13)
Frantic activity revealed in dusty stellar factories
Thanks to the Very Large Telescope's acute and powerful near-infrared eye, astronomers have uncovered a host of new young, massive and dusty stellar nurseries in nearby galaxy NGC 253. The centre of this galaxy appears to harbour a twin of our own Milky Way's supermassive black hole. view more (2009-01-21)
Nearly a century later, new findings support Warburg theory of cancer
German scientist Otto H. Warburg's theory on the origin of cancer earned him the Nobel Prize in 1931, but the biochemical basis for his theory remained elusive. view more (2009-01-12)
A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle. view more (2007-03-13)
New technology could lead to camera based on human eye
Digital cameras have transformed the world of photography. Now new technology inspired by the human eye could push the photographic image forward even more by producing improved images with a wider field of view. view more (2008-08-07)
