~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The Raelian Movement for those who are not afraid of the future : http://www.rael.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Scientists make 'sonic screwdriver' http://www.guardian.co.uk/uk/feedarticle/10202626 Press Association, Thursday April 19 2012 Physicists at the University of Dundee used equipment designed for MRI-guided ultrasound surgery and created a tool that can lift and spin a 10cm rubber disk with an ultrasound beam. The team said the beam carries momentum that can push an object in its path and can cause the object to rotate when shaped like a helix or vortex. Mike MacDonald, of the university's Institute for Medical Science and Technology, said: "This experiment not only confirms a fundamental physics theory but also demonstrates a new level of control over ultrasound beams which can also be applied to non-invasive ultrasound surgery, targeted drug delivery and ultrasonic manipulation of cells. "The 'sonic screwdriver' device is also part of the EU-funded Nanoporation project where we are already starting to push the boundaries of what ultrasound can do in terms of targeted drug delivery and targeted cellular surgery. "It is an area that has great potential for developing new surgical techniques, among other applications, something which Dundee is very much at the forefront of." Doctor Who uses his screwdriver to open locks and doors and control other devices, but the Dundee team believes its study could help make surgery using ultrasound techniques more precise and effective by giving doctors the ability to steer ultrasound waves to the precise spot where they are needed. Ultrasound waves allow surgeons to treat a range of conditions without having to cut a patient open. Dr MacDonald added: "Like Doctor Who's own device, our sonic screwdriver is capable of much more than just spinning things around." The results of the research are published in the American Physical Society's journal Physical Review Letters. Last year, scientists in Bristol began working on their own "sonic screwdriver" to be used in DIY. The team experimented with rotating ultrasonic force fields which acted like the head of a screwdriver.

"Selected by RAEL" means that I believe it is important for the people of this planet to know about what people think or do, even when what they think or do is completely stupid and against our philosophy. When I selected articles in the past about stupid Christian fundamentalists in America praying for rain, I am sure no Rael-Science reader was stupid enough to believe that I was supporting praying to change the weather. So, when I select articles which are in favor of drugs, anti-Semitic, anti-Jewish, racist, revisionist, or inciting hatred against any group or religion, or any other stupid article, it does not mean that I support them. It just means that it is important for all human beings to know about them. Common sense, which is usually very good among our readers, is good enough to understand that. When, like in the recent articles on drug decriminalization, it is necessary to make it clearer, I add a comment, which in this case was very clear: I support decriminalizing all drugs, as it is stupid to throw depressed and sad people (as only depressed and sad people use drugs) in prison and ruin their life with a criminal record. That does not mean that there is any change to the Message which says clearly that we must not use any drug except for medical purposes. The same applies to the freedom of expression which must be absolute. That does not mean again of course that I agree with anti-Jews, anti-Semites, racists of any kind or anti-Raelians. But by knowing your enemies or the enemies of your values, you are better equipped to fight them. With love and respect of course, and with the wonderful sentence of the French philosopher Voltaire in mind: "I disapprove of what you say, but I will defend to the death your right to say it". -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Ethics" is simply a last-gasp attempt by deist conservatives and orthodox dogmatics to keep humanity in ignorance and obscurantism, through the well tried fermentation of fear, the fear of science and new technologies. There is nothing glorious about what our ancestors call history, it is simply a succession of mistakes, intolerances and violations. On the contrary, let us embrace Science and the new technologies unfettered, for it is these which will liberate mankind from the myth of god, and free us from our age old fears, from disease, death and the sweat of labour.
