Field guide for confirming new earth-like planets described
Astronomers looking for earth-like planets in other solar systems - exoplanets - now have a new field guide thanks to earth and planetary scientists at Washington University in St. Louis.   view more (2005-09-08)

Astronomers detect echoes from ancient supernovae
A team of astronomers has found faint visible "echoes" of three ancient supernovae by detecting centuries-old light reflected by interstellar gas clouds hundreds of light-years removed from the original explosions.   view more (2005-12-22)

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)

Max Planck researchers channel microcapsules into tumour cells and release their contents using a laser impulse
Treating malignant tumours is difficult. Doctors have to destroy the tumour, but healthy tissue needs to be preserved. Chemotherapy tends to kill diseased cells, at the same time causing great damage to the body in general.   view more (2006-08-24)

Nanoscale microscope sheds first light on gene repair
Proteins called H2AX act as "first aid" to DNA, among other roles. For the first time, scientists using the world's most powerful light microscope (the only one of its kind in the Americas) have seen how H2AX is distributed in the cell nucleus: in clusters, directing the first aid/repair... view more (2006-11-14)

Stanford innovation helps 'enlighten' silicon chips
Light can carry data at much higher rates than electricity, but it has always been too expensive and difficult to use light to transmit data among silicon chips in electronic devices.   view more (2005-10-27)

NIST method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes.   view more (2006-02-17)

NRC team uses new Quantum Technology to control molecules
A research team at the National Research Council Canada (Ottawa) has developed a new quantum technology which uses laser pulses to control quantum processes.   view more (2006-10-13)

Key to early diagnosis of autism may be in the placenta
Researchers at Yale School of Medicine have discovered in the placenta what may be the earliest marker for autism, possibly helping physicians diagnose the condition at birth, rather than the standard age of two or older.   view more (2006-06-26)

Carbon-based quantum dots could mean 'greener' safer technology in medicine and biology
Chemists at Clemson University say they have developed a new type of quantum dot that is the first to be made from carbon.   view more (2006-05-24)

NYU physicists find way to create three-dimensional quasicrystals
New York University physicists have applied a ground-breaking nanotechnology method to create three-dimensional quasicrystals, highly ordered structures that, unlike conventional crystals, never repeat themselves.   view more (2005-07-12)

New light microscope may help unlock some of cells' secrets
A microscopy technique pioneered with the help of Florida State University's National High Magnetic Field Laboratory has led to the development of a new light microscope capable of looking at proteins on a molecular level.   view more (2006-08-17)

Light-sensing cells in retina develop before vision
Investigators at Washington University School of Medicine in St. Louis have found that cells making up a non-visual system in the eye are in place and functioning long before the rods and cones that process light into vision.   view more (2005-12-22)

Metamaterials four to work for visible light
For the first time ever, researchers at the U.S. Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light.   view more (2007-01-05)

Titanium dioxide — It slices, it dices ...
Chemists from the National Institute of Standards and Technology (NIST) and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis.   view more (2007-04-02)

DNA gets new twist: Carnegie Mellon scientists develop unique 'DNA nanotags'
Carnegie Mellon University scientists have married bright fluorescent dye molecules with DNA nanostructure templates to make nanosized fluorescent labels that hold considerable promise for studying fundamental chemical and biochemical reactions in single molecules or cells.   view more (2007-01-29)

Near infrared laser device can measure brain oxygen levels
A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.   view more (2005-10-24)
