Biocompatibility to Ensure Body Friendly Parts
In recent years, the solution to the problem of diseased or damaged organs has been to replace the old with the new. By taking tissue from either a patient or a donor, surgeons have transplanted this to the damaged area and given many people a new lease of life. The method is not without limitations, however. Issues such as the availability of... view more... (2003-06-06)
Early treatment of children with bilateral amblyopia essential, according to multisite study
When a child is farsighted or has astigmatism or has both conditions in both eyes, bilateral amblyopia may develop. In contrast to single-eye amblyopia or "lazy eye," where one eye presents an unclear image to the brain, bilateral amblyopia affects both eyes and is less common. view more (2007-10-02)
MIT scientists create fiber webs that see
In a radical departure from conventional lens-based optics, MIT scientists have developed a sophisticated optical system made of mesh-like webs of light-detecting fibers. view more (2006-07-18)
New 'liquid lens' data for immersion lithography
New data on the properties of potential "liquid lenses" compiled by the National Institute of Standards and Technology (NIST) could help the semiconductor industry continue to shrink feature sizes on computer chips. view more (2006-03-21)
Freeing light shines promise on energy-efficient lighting
The latest bright idea in energy-efficient lighting for homes and offices uses big science in nano-small packages to dim the future Edison's light bulb. view more (2008-07-16)
Sheffield engineers have big ideas for the latest in medical scanners
Engineers at the University of Sheffield and STFC Rutherford-Appleton Laboratories have developed one of the World's largest imagers that could form the heart of future medical scanners. view more (2008-02-13)
Solar Power Game-Changer: "Near Perfect" Absorption of Sunlight, From All Angles
Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. view more (2008-11-04)
New lens device will shrink huge light waves to pinpoints
Manipulating light waves, or electromagnetic radiation, has led to many technologies, from cameras to lasers to medical imaging machines that can see inside the human body. view more (2007-07-13)
Electric Nudge toward Self-organization
In search of materials with nonlinear optical properties Window panes and eyeglass lenses that get darker as it gets brighter are especially great in the summer. Their secret lies in optical properties that change as the light intensity changes - nonlinear optical properties. Such materials are also of interest as optoelectronic components. One... view more... (2002-03-07)
T-ray breakthrough could make detecting disease far easier
A breakthrough in the harnessing of 'T-rays'-electromagnetic terahertz waves-which could dramatically improve the detecting and sensing of objects as varied as biological cell abnormalities and explosives has been announced. view more (2006-11-03)
Antibacterial coatings cut infection rates
Putting antibacterial coatings on hip and knee implants and biomedical devices such as catheters could cut infection rates following surgery and significantly reduce health care costs and improve quality of life for patients. view more (2005-11-30)
Nanocups brim with potential
Researchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices. view more (2009-03-16)
HIV research project scoops innovation prize
Research that could lead to a breakthrough in the treatment of HIV has scooped a University of Manchester scientist a prestigious industry award. view more (2004-11-23)
The crew will soon be able to watch you from the cockpit
AIRBUS, the European jet manufacturer, is planning to build concealed cameras into the light fittings above the seats in its aircraft. The idea is to let the crew monitor passengers and spot hijackers before they strike. The cameras also work in the dark. The move is part of an attempt to reassure... view more... (2002-05-08)
'T-ray' devices with perfect imaging abilities move a step closer
A team of American and British scientists has demonstrated an artificially made material that can provide a magnetic response to Terahertz frequency radiation, bringing the realisation and development of novel 'T-ray' devices a step closer. The advance, reported in the journal Science today (5 March), suggests many applications in biological and... view more... (2004-03-04)
Adults with lazy eye can improve
Young adults with amblyopia, or lazy eye, can improve substantially and retain their gains under a new treatment developed by researchers at USC and three Chinese universities. view more (2005-12-21)
Soft materials buckle up for measurement
Buckling under pressure can be a good thing, say materials scientists at the National Institute of Standards and Technology (NIST). view more (2006-06-28)
Holograms make for better vision tests
A new paper published in the July 1 issue of OSA's Optics Letters shows that researchers in Australia have created a new one-step test that uses holograms to diagnose the astigmatic error of the human eye, a key measurement in determining the appropriate prescriptions for eye glasses in patients. view more (2007-07-09)
Doctors cut repeat LASIK visits dramatically
Ophthalmologists have developed a formula that slashes by nearly two-thirds the likelihood that patients will need repeat visits to an eye surgeon to adjust their vision after their initial LASIK visit. view more (2006-09-19)
Promising new metamaterial could transform ultrasound imaging
Using the same principles that help create a guitar's complex tones, researchers at the University of California, Berkeley, have developed a new material that holds promise for revolutionizing the field of ultrasound imaging. view more (2006-06-01)
