Magnetism flicks switch on 'dark excitons'
In new experimental research appearing in this week's issue of Physical Review Letters, a Rice University-led team of nanoscientists and electrical engineers has flipped the switch on 'dark excitons' in carbon nanotubes by placing them inside a strong magnetic field.   view more (2006-01-11)

Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more... view more (2007-03-05)

Fluorescence Diffuse Optical Tomography Provides High Contrast, 3-D Look at Breast Cancer
Researchers at the University of Pennsylvania have created the first three-dimensional optical images of human breast cancer in patients based on tissue fluorescence.   view more (2007-06-14)

European Water Directive: Optical sensors detect minute amounts of pollutants
Minute amounts of organic pollutants-including oestrone-can now be detected in river water as a result of a new optical sensing instrument realised in a project funded by the EU's Environment Programme.   view more (2004-09-01)

One shot of gene therapy spreads through brain in animal study
By targeting a site in a mouse brain well connected to other areas, researchers successfully delivered a beneficial gene to the entire brain-after one injection of gene therapy. If these results in animals can be realized in people, researchers may have a potential method for gene therapy to treat... view more (2007-10-09)

Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions.   view more (2007-01-31)

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... view more (2008-07-28)

Virtual Colonoscopy Effective in Preventing Colorectal Cancer
Three-dimensional computed tomography (CT) colonography, also known as virtual colonoscopy, is an accurate screening method for colorectal cancer.   view more (2006-10-18)

Nano surfaces could slash cost of solar energy
Nanotechnologies which can artificially change the optical properties of materials to allow light to be trapped in solar cells could greatly reduce the cost of solar energy.   view more (2005-02-03)

A research team led by Carnegie Mellon University Materials Science and Biomedical Engineering Professor Prashant Kumta has discovered a nanocrystalline material that is cheaper, more stable and produces a higher quality energy storage capacity for use in a variety of industrial and portable... view more (2006-07-11)

Microfluidics and optical trapping integrated for the first time in new lab-on-a-chip research
Researchers at Cornell University for the first time have integrated optical functions with microfluidic ones, enabling the sorting of particles by light.   view more (2007-10-26)

European light research opens door for optical storage and computing
The goal of replacing electronics with optics for processing data in computers is coming closer through cutting edge European research into the mysterious properties of "fast and slow" light.   view more (2008-04-25)

Preservation of fresh-cut vegetables; a producer's and consumer's sake
In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the '80s in the UK. Their market is yearly... view more (2002-03-19)

Computer scientists develop solutions for long-term storage of digital data
Although the digital age is well under way, one crucial detail remains to be worked out--how to store vast amounts of digital information in a way that allows future generations to recover it.   view more (2008-04-22)

In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location.   view more (2007-02-08)

Denser computer chips possible with plasmonic lenses that 'fly'
Engineers at the University of California, Berkeley, are reporting a new way of creating computer chips that could revitalize optical lithography, a patterning technique that dominates modern integrated circuits manufacturing.   view more (2008-10-23)

Into the Epoch of Galaxy Formation
Current theories hypothesize that more than 80% of all stars ever formed were assembled in galaxies during the latter half of the elapsed lifetime of the Universe, i.e., during the past 7-8 billion years.   view more (2000-02-17)

Building blocks of the future
Structure and properties of carbon nanostructures The discovery in 1985 of fullerenes, tiny carbon balls of nanometer dimensions, ushered in a new era in international science. Only a few years later (1991) scientific interest also started to focus on so-called carbon nanotubes. The discovery of... view more (2002-12-05)

New Human Genetics Commission Announces 2000/2001 Workplan
