Corneal transplant technique shows promise in children
For infants and children with blinding diseases of the cornea, a sophisticated new corneal transplantation technique offers the hope of improving vision while overcoming the technical difficulty and low success rate of traditional penetrating keratoplasty (PK) in children, according to reports in the current issue of the Journal of AAPOS (American... view more...

RUBBER BULLETS NOT SAFE FOR CROWD CONTROL (p 1795)
A study in this week's issue of THE LANCET which highlights the injuries sustained by Arab demonstrators after clashes with Israeli forces in 2000 concludes that rubber bullets are not a safe form of ammunition for crowd control. Rubber bullets were first used by British forces in Northern Ireland in 1970. These missiles are intended to inflict... view more... (2002-05-22)
Safety, efficacy of corneal transplant procedure confirmed; an antibiotic can cause double vision
Highlights of September's Ophthalmology, the journal of the American Academy of Ophthalmology (Academy), include a 2009 review by the Academy of the safety and efficacy of a widely used corneal transplant procedure and a warning about an unusual but serious reaction to systemic fluroquinolones, a class of antibiotics used to treat a variety of... view more...

Bottleneck in Blood Supply Makes Brain Vulnerable to Strokes
A team of UC San Diego physicists and neuroscientists has discovered a bottleneck in the network of blood vessels in the brain that makes it vulnerable to strokes. The finding may explain the origin of the puzzling damage to the brain's gray matter often detected in brain scans, especially among the elderly. view more (2007-01-05)
Laser surgery does not appear to have long-term effects on corneal cells
Laser eye surgery to correct vision problems does not appear to be associated with lasting changes to cells lining the inside of the cornea at nine years after the procedure. view more (2009-11-10)
Breaking the 'mucus barrier' with a new drug delivery system
Chemical engineers from Johns Hopkins University have broken the "mucus barrier," engineering the first drug-delivery particles capable of passing through human mucus - regarded by many as nearly impenetrable - and carrying medication that could treat a range of diseases. Those conditions include lung cancer, cervical cancer and cystic... view more... (2008-08-20)
Tunnel vision
Criminals of all kinds are digging tunnels along the U.S. border at a fast and furious pace. Of every tunnel ever discovered by U.S. border patrol agents, 60 percent have been found in the last three years. Agents spot a new one every month. view more (2009-06-30)
New cancer weapon: nuclear nanocapsules
Rice University chemists have found a way to package some of nature's most powerful radioactive particles inside DNA-sized tubes of pure carbon -- a method they hope to use to target tiny tumors and even lone leukemia cells. view more (2007-08-24)
Nanotech coating could lead to better brain implants to treat diseases
Biomedical and materials engineers at the University of Michigan have developed a nanotech coating for brain implants that helps the devices operate longer and could improve treatment for deafness, paralysis, blindness, epilepsy and Parkinson's disease. view more (2009-03-11)
TIMMI2 Images the Heart of the Orion Nebula
A new astronomical instrument, TIMMI2, has just been installed on the ESO 3.6-m telescope at La Silla. The first images have now been obtained and hold great promise for future research programmes with this facility. The Thermal Infrared MultiMode Instrument was built in a collaboration between ESO and a consortium headed by the Jena University... view more... (2001-03-30)
LAND MINES LEGACY REMAINS DESPITE BAN:
The Second International Conference on the Detection of Abandoned Land Mines, to be held in Edinburgh, 12-14 October, 1998 will hear experts from some 18 countries describe the progress being made on a whole range of approaches to this problem. view more (1998-08-19)
Nanoneedle is small in size, but huge in applications
Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. view more (2009-04-29)
Human immunodeficiency virus (HIV) treatment
Russian researchers have developed a medication capable of protecting against various human immunodeficiency virus (HIV) strains. Their effort has been supported by the International Scientific Technical Center. Intense search for efficacious human immunodeficiency virus treatment carried out by scientific laboratories worldwide has not yet... view more... (2004-01-30)
Details of solar particles penetrating the Earth's environment revealed
Co-ordinated efforts by China/ESA's Double Star and ESA's Cluster spacecraft have allowed scientists to zero in on an area where energetic particles from the Sun are blasting their way through the Earth's magnetic shield. view more (2006-10-04)
Reading the brain without poking it
Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. view more (2009-06-29)
TU Delft demonstrates for the first time how light squeezes through small holes
How does light pass through a tiny hole" For the first time, Dr Aurele Adam and Prof. Paul Planken of Delft University of Technology, in conjunction with two South Korean and one German research groups, have succeeded in mapping this process properly. view more (2008-05-09)
Integral - tracking extreme radiation across the Universe
The world`s most advanced gamma-ray space telescope Integral [International Gamma Ray Astrophysics Laboratory] was successfully launched today [17 October 2002] from the Baikonur Cosmodrome, Kazakhstan. Integral will provide first-hand observations of cosmic objects that release some of the most energetic radiation of the Universe. British... view more... (2002-10-11)
