No Evidence That WHO-recommended Treatment For Insecticide Poisoning Improves SurvivalA new study finds no evidence to suggest that a controversial antidote recommended by the World Health Organization (WHO) to treat patients poisoned with highly toxic insecticides improves their chance of survival. The results may even add weight to existing concerns about pralidoxime, the treatment recommended by the WHO, by suggesting that it could be harmful in patients who have deliberately poisoned themselves with insecticides.Source: ScienceDaily: Latest Science News | 6 Jul 2009 | 3:00 am Researchers Unveil Whiskered Robot RatScientists have developed an innovative robot rat which can seek out and identify objects using its whiskers.

Source: Yahoo! News: Science News | 5 Jul 2009 | 4:55 am Hope for blindness cure with laser breakthroughPulses of light clean key membrane to prevent the onset of macular degeneration Millions of people could have their eyesight saved thanks to ground-breaking laser treatment that has the potential to eradicate the most common cause of blindness. One of Britain's leading eye experts has developed a technique to reverse the disabling effects of age-related macular degeneration (AMD), which leaves many older people unable to read, drive or live independently, and eventually robs them of sight in one or both eyes. Professor John Marshall has developed a way of "cleaning" eyes which, due to the ageing process, have accumulated tiny particles of debris which start to cloud their sight. His pioneering technique uses a painless "short pulse" laser to solve the otherwise intractable problem of how to help the eye's waste disposal system do its job after it has been weakened by age. Marshall, a senior ophthalmologist at King's College London, said he hopes this "retinal regeneration therapy" could prevent and reverse the onset of AMD. The technique works by rejuvenating a thin membrane behind the retina, called Bruch's membrane. Over time this membrane becomes so "clogged" with the by-product of cell renewal that vital nutrients can no longer cross from the bloodstream into the retina and excess material becomes trapped, unable to pass in the other direction. This leads to the death of retinal cells and, in time, to AMD and eventual blindness. Marshall's technique promises to prevent and even reverse the process, allowing the eye to return to something like its youthful, uncluttered state. In a clinical trial involving more than 100 diabetics, Marshall found that focusing a laser beam on one part of the retina helps stimulate the release of enzymes, which then set about cleaning up the waste material. Participants reported this led to a marked improvement in their sight. Marshall now plans to conduct a wider trial among those suffering the early stages of AMD. In most cases the "clogging" begins when people reach their mid-40s, but does not always lead to significant sight loss. Some are more at risk, because of a number of factors in addition to their age. These include genetics - such as a family history of AMD. Women are more likely to suffer, and environmental factors can play a part, with smokers at greater risk. AMD is the leading cause of blindness in those aged over 60 in the western world. Initially it causes blurred or distorted central vision, but worsens over time leaving sufferers unable to do everyday tasks. About a quarter of all over-60s in the UK suffer some loss of vision as a result of the condition. Eye specialists say Marshall's discovery could mark a breakthrough in tackling the condition. There is currently no effective treatment for "dry" AMD - the less serious form of the disease. The drugs Lucentis and Avastin are used to treat the more disabling and aggressive "wet" version, but these usually do little more than stabilise the condition. Marshall's use of laser technology to restore an ailing eye could therefore open up a whole new method of treatment. Conventional lasers have been used previously, but they have damaged the eye's light-sensitive cells in the process. Marshall said: "The laser I've used is a totally new soft-pulse laser which doesn't cause any damage to any of the nearby tissues, unlike conventional lasers. All it does is stimulate the required chemical reaction. And it treats both 'dry' AMD and the effects of ageing." Marshall's next clinical trial of the technique will be with patients who are already being treated for AMD in one eye. He hopes that it will prove that treating the patient's other eye will delay the onset of AMD by up to seven years. If further trials are successful, it could open many possibilities. "In the short term it could benefit anybody with a family history or with diagnostic signs that they are at high risk of AMD," Marshall said. "In the longer term it could be that we all decide to have our retinas cleaned so that we don't develop these problems later in life." Eyesight specialists say Marshall's research could be of huge importance. Tom Pey of Guide Dogs for the Blind, which funded the work, said: "This is potentially a huge breakthrough for millions of people across the world." guardian.co.uk © Guardian News & Media Limited 2009 | Use of this content is subject to our Terms & Conditions | More Feeds
Source: Science news, comment and analysis | guardian.co.uk | 4 Jul 2009 | 11:01 pm One thing is sure, it was a man's stepWhere the Eagle daredThe Moon landings bear remarkable testimony not so much to "human" or "American" achievement but to the achievements of western, that is, European, civilisation, the culmination of more than 2,500 years of cultural, scientific and technological developments (not forgetting the contributions of Babylonian, Islamic, Hindu, Chinese and other civilisations) ("Apollo ... the dream that fell to Earth", 21 June). They also provide evidence of European man's continuing drive for power and advantage over others, and his ability to rationalise and deceive himself into believing that his motivations are noble. The actual motivations for putting men on the Moon were contemptible (a Darwinian demonstration of power), but then so too were the motivations for commissioning much of our greatest works of art. If only we were to recognise ourselves for the apes that we still are, we might yet save ourselves from self-destruction. Robin McKie calculates the cost of the Apollo programme at "about $1 trillion in today's money". All spent on reaching a lifeless environment incapable of supporting life. One wonders how far $1tn would go in averting climate change catastrophe on Earth by replacing fossil fuel with renewable sources of energy such as wind and sunshine. To add some perspective, whilst the Apollo programme may have cost $24bn in 1960s money, the Vietnam war cost $111bn. Robin McKie's excellent overview of the Apollo project is a striking story of brave men, technology, money and cold war competitive folly. But the other hidden histories behind the Apollo era involve the women, all great pilots, who were trained by NASA but then ditched in an act of blatant sexism. These women, the Mercury 13, were all selected by NASA at end of the 1950s to be trained for the space programme. Jerri Truhill was the leading light, a glamorous, tough-talking Texan, wife and mother and a superb aviator (she flew perilous reconnaissance missions over Cuba during the 1960s missile crisis). In Ulrike Kubatta's documentary She Should Have Gone to the Moon, Truhill tells how the women outperformed men in all the training tests (including water tank isolation) but how ultimately, the authorities, with the approval of President Johnson, stipulated that they would "rather send monkeys into space than a woman". Architecture's young gunsIn the context of HRH vs Rogers ("The young generation with new vision to build Britain", 21 June), you might as well read Sergison Bates, Caruso St John, Fretton and a host of others for FAT and Muf, as they all came to prominence at about the same time and are all besotted with different takes on the 'contextualism' agenda. In this post-post modern age of global warming, with the failures of the 60s and 70s behind us, it is all too easy for those simply lucky enough to be born sometime after 1960 to make fun of their artistic and professional forebears. Let's see how besotted they are with contextualism if they ever get an opportunity to do a big project. The avant garde are always doomed to become the orthodoxy. The first is spring, the second is winter, and the media play a major part in changing the seasons. The young guns, always desperate to be noticed, are willing accomplices in the game. guardian.co.uk © Guardian News & Media Limited 2009 | Use of this content is subject to our Terms & Conditions | More Feeds
