Thomas Kohnen of the Goethe University in Frankfurt and his coauthors discuss cataract surgery with the implantation of an artificial lens in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2009; 106[43]: 695). http://www.physorg.com/news176995980.html Medicine & Health Mon, 09 Nov 2009 14:10:09 EST news176995980 New research reveals how proteins that are critical for the transparency of the eye lens are properly sorted and localized in membrane bilayers. The study, published by Cell Press in the November 3rd issue of Biophysical Journal, analyzes how interactions between lipid and protein molecules can selectively concentrate proteins in certain regions of the cell membrane. http://www.physorg.com/news176474807.html Biology Tue, 03 Nov 2009 13:50:06 EST news176474807 (PhysOrg.com) -- David Smith, who has been building model railroads since 1965, has always had a preference for the smaller scale train models. His most recent project is a five-car train that runs through a scene of mountains, a tunnel, trees, buildings, and a cloud-studded sky - the whole thing measuring just 0.125 x 0.2 inches (0.3 x 0.5 cm). The train's modeling scale is 1:35,200. http://www.physorg.com/news175782519.html Technology Mon, 26 Oct 2009 13:29:14 EST news175782519 Sony today announced the development of a single lens 3D camera technology capable of recording natural and smooth 3D images of even fast-moving subject matter such as sports, at 240fps (frames per second). http://www.physorg.com/news173634913.html Technology Thu, 01 Oct 2009 17:10:01 EST news173634913 (PhysOrg.com) -- Researchers at Cornell University have developed a device called a "time lens" which is a silicon device for speeding up optical data.

Their technique, which was published in the January 2009 edition of the Journal of Synchrotron Radiation, could prove extremely valuable in the study of nanomaterials at future synchrotron light sources. http://www.physorg.com/news168536133.html Nanotechnology Mon, 03 Aug 2009 16:36:13 EST news168536133 The human eye lens consists of a highly concentrated mix of several proteins. Protective proteins prevent these proteins from aggregating and clumping. If this protective function fails, the lens blurs and the patient develops cataracts. http://www.physorg.com/news168253150.html Biology Fri, 31 Jul 2009 10:10:01 EST news168253150 Implantable lenses made of a collagen-like substance appear to provide stable correction of moderate to high nearsightedness (myopia) over four years of follow-up, according to a report in the July issue of Archives of Ophthalmology. http://www.physorg.com/news166729196.html Medicine & Health Mon, 13 Jul 2009 19:00:01 EST news166729196 Errant pixels and blurry regions in a photo, whether digital or scanned, are the bane of photographers everywhere. Moreover, in vision processing research degraded photos are common and require restoration to a high-quality undegraded state. Research published this month in the International Journal of Signal and Imaging Systems Engineering could provide new insights. http://www.physorg.com/news166267590.html Technology Wed, 08 Jul 2009 10:27:54 EST news166267590 (PhysOrg.com) -- Imagine a soldier's uniform made of a special fabric that allows him to look in all directions and identify threats that are to his side or even behind him. In work that could turn such science fiction into reality, MIT researchers have developed light-detecting fibers that, when weaved into a web, act as a flexible camera. Fabric composed of these fibers could be joined to a computer that could provide information on a small display screen attached to a visor, providing the soldier greater awareness of his surroundings. http://www.physorg.com/news166182832.html Nanotechnology Tue, 07 Jul 2009 10:55:48 EST news166182832 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. http://www.physorg.com/news163844569.html Medicine & Health Wed, 10 Jun 2009 09:23:16 EST news163844569 (AP) -- Contact lens maker Bausch & Lomb Inc. had an overriding reason for going private in 2007: It wanted to handle a devastating recall of its flagship lens cleaner, its chief executive said, "without a lot of outside distraction." http://www.physorg.com/news162995611.html Medicine & Health Sun, 31 May 2009 13:33:39 EST news162995611 While the majority of patients with common vision problems can find glasses or contact lenses fairly easily, others who suffer from diseases of the eye that affect the focus of light have more limited options and may simply have to learn to live with poor vision. http://www.physorg.com/news161441645.html Medicine & Health Wed, 13 May 2009 13:54:31 EST news161441645 (PhysOrg.com) -- Researchers from the University of Arizona have created a fluid-based opthalmic lens in which the amount of fluid can be constantly adjusted to provide customized eye correction. The lens may one day be incorporated into the tools that eye doctors use to determine prescription strength. http://www.physorg.com/news154705159.html Physics Tue, 24 Feb 2009 13:40:08 EST news154705159 Starting with the tiny fruit fly and then moving into mice and humans, researchers at VIB and K. U. Leuven show that expression of the same gene suppresses cancer in all three organisms. Reciprocally, switching off the gene - called Ato in flies and ATOH1 in mammals - leads to cancer. The authors show there is a good chance that the gene can be switched on again with a drug. They report their findings in two papers in the leading online open access journal PLoS Biology. http://www.physorg.com/news154618409.html Medicine & Health Mon, 23 Feb 2009 13:33:57 EST news154618409 (PhysOrg.com) -- Distorted cell-phone photos and big, clunky telephoto lenses could be things of the past.

But even had the economy been good, the tech industry wouldn't have earned many headlines. In short, there was nothing comparable to the debut of the iPhone or even Windows Vista. http://www.physorg.com/news150654161.html Technology Thu, 08 Jan 2009 16:22:41 EST news150654161 The remarkable ability of insects to look in all directions at once has been emulated by a team of international scientists who have built an artificial 'eye' with an unobstructed all-round view. http://www.physorg.com/news150385501.html Technology Mon, 05 Jan 2009 13:45:01 EST news150385501 Exposure to prolonged temperature elevation reduces antifungal activity of a contact lens solution that was implicated in the epidemic of the eye infection Fusarium keratitis that occurred between 2004 and 2006, according to a report in the November issue of Archives of Ophthalmology, one of the JAMA/Archives journals. http://www.physorg.com/news145557725.html Medicine & Health Mon, 10 Nov 2008 16:42:05 EST news145557725 Due to their underground habitats, moles' eyes have been modified by natural selection in ways very different from those of surface-dwelling animals. New research, published in the open access journal BMC Biology, features a detailed anatomical and genetic examination of the changes that result from living life in the dark. http://www.physorg.com/news143787509.html Biology Tue, 21 Oct 2008 05:58:29 EST news143787509 (PhysOrg.com) -- By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous burst of star formation. http://www.physorg.com/news143736009.html Space & Earth Mon, 20 Oct 2008 15:40:09 EST news143736009 Contact lenses increase the risk of infection with pathogenic protozoa that can cause blindness.

But how does the surface of the lens have to be structured in order to focus the light in the shape of a specific pattern? This used to be a task that took hours - now it can be done in a few seconds. http://www.physorg.com/news142098016.html Technology Wed, 01 Oct 2008 16:40:16 EST news142098016 New miniature image-capturing technology powered by water, sound, and surface tension could lead to smarter and lighter cameras in everything from cell phones and automobiles to autonomous robots and miniature spy planes. http://www.physorg.com/news141300733.html Physics Mon, 22 Sep 2008 11:12:13 EST news141300733 Glasses embedded with a telescope promise to make it easier for people with impaired vision to drive and do other activities requiring sharper distance vision.
