Measuring in 3-D
Today, complex optical free-form geometries are used primarily in car headlamps and in optics for cameras and digital projectors. These optical components are expensive to manufacture and to test.   view more (2008-04-17)

Strengthening Fluids With Nanoparticles
Researchers at Rensselaer Polytechnic Institute have demonstrated that liquids embedded with nanoparticles show enhanced performance and stability when exposed to electric fields. The finding could lead to new types of miniature camera lenses, cell phone displays, and other microscale fluidic devices.   view more (2008-02-20)

Sight for sore eyes
In a world-first breakthrough, University of New South Wales (UNSW) medical researchers have used stem cells cultured on a simple contact lens to restore sight to sufferers of blinding corneal disease.   view more (2009-06-10)

New Research Shows Owning a Dog Helps People Make Friends
Dogs can act as powerful social catalysts, making it easier for people to make social contact with each other. This effect is the same in different locations and with differences in the appearance of the dogs or handlers. Quite simply, people are motivated to make conversation if there is a safe topic available. Dogs appear to fulfil this role.... view more... (2000-02-09)

Effective solar cells and sensitive bioanalysis
The efficiency factor of solar cells is crucial for the success of generating electricity from sunlight. Systems in which light is concentrated 400-fold through lenses onto solar cells are proving to be particularly advantageous.   view more (2009-06-26)

Turning sound into light
Actors who perform in musicals often sweat in torrents when they have to zap around the stage on roller-skates or sing a ballad under a burning spotlight, dressed in bearskin. To allow the audience to hear them clearly, the artists wear cleverly hidden microphones underneath their make-up and costume. But as soon they break into a sweat, the... view more... (2003-09-18)

Kiwi astronomers help find icy 'Super Earth' - Life in space discovery a step closer
By designing a variant of an astronomical technique proposed by Einstein, researchers from The University of Auckland and Massey University, together with astronomers from Auckland's Stardome Observatory, have found evidence for a new icy "Super Earth".   view more (2006-03-15)

New 'implanted contacts' designed to fix nearsightedness
UT Southwestern Medical Center ophthalmologists will be the first in the area to insert a new type of implanted lens to fix nearsightedness.   view more (2006-02-28)

An artificial cornea is in sight, thanks to biomimetic hydrogels
If eyes are "the windows of the soul," corneas are the panes in those windows. They shield the eye from dust and germs. They also act as the eye's outermost lens, contributing up to 75 percent of the eye's focusing power.   view more (2006-09-12)

Metamaterials with new electromagnetic properties
The development of new types of artificial materials, known as "metamaterials" and with electromagnetic properties not found in nature, is the aim of the Metamorphose Excellence European Network, of which the Public University of Navarre forms part, together with twenty-one other research institutions from 13 European countries.   view more (2004-03-25)

Mars Express: no signal from Beagle 2 so far
ESA's Mars Express orbiter made its first attempt to establish contact with the Beagle 2 lander, after the two spacecraft separated on 19 December 2003. The orbiter made its first pass over the Beagle 2 landing site today at 13:13 CET, but could not pick up any signal from the tiny lander. More attempts to contact Beagle 2 are planned in the... view more... (2004-01-07)

University of Warwick Designer Polymer Company Wins Business Equivalent of Pop Idol Competition
A University of Warwick spin-out company specialising in designer polymers has won the prestigious Enterprise Launch Pad award at this year's Cambridge Enterprise Conference. The company, Warwick Effect Polymers, wins £5,000 but also importantly it gives them entrance to a "deal day" where a select group of companies get the... view more... (2002-09-19)

Jury still out over risks of heading a soccer ball
Heading the ball in soccer is unlikely to cause brain injury but head to head collisions might, says a leading sports physician in this week’s BMJ.   view more (2003-08-12)

Spookfish uses mirrors for eyes
A remarkable new discovery shows the four-eyed spookfish to be the first vertebrate ever found to use mirrors, rather than lenses, to focus light in its eyes.    view more (2009-01-08)

New evidence for dark energy in the universe
An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious "Dark Energy". The new evidence comes from a 10-year census of the sky for examples of gravitational lenses, which are seen when a galaxy bends the light from a... view more... (2002-11-09)

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)

Weekly contact with drug reps linked to unnecessary prescribing
General practitioners who see drug industry representatives at least once a week are more likely to express views that will lead to unnecessary prescribing then those who report less frequent contact, finds a study in this week’s BMJ.   view more (2003-05-28)

Hubble finds large sample of very distant galaxies
New Hubble Space Telescope observations of six spectacular galaxy clusters acting as gravitational lenses have given significant insights into the early stages of the Universe. Scientists have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at a distance of 13 billion light-years (~redshift... view more...

Divorced parents 'make conflict worse by going to court over child contact'
Divorced and separated parents who resort to the law to settle chronic disputes over contact with their children risk making matters worse for all concerned. Research for the Joseph Rowntree Foundation contrasts the relative success of contact agreements that separated parents reach without legal intervention with the stress placed on children... view more...

Deep magmatic plumbing of mid-ocean ridges revealed
Some of the highest quality images ever taken of the Earth's lower crust reveal that the upper and lower crust form in two distinctly different ways.   view more (2005-08-25)
