The first experimental demonstration of quantum telecloning has been achieved by scientists at the University of Tokyo, the Japan Science and Technology Agency, and the University of York. Telecloning combines cloning (or copying) with teleportation; ie, disembodied transport. The scientists have succeeded in making the first remote copies of beams of laser light, by combining quantum cloning with quantum teleportation into a single experimental step. Telecloning is more efficient than any combination of teleportation and local cloning because it relies on a new form of quantum entanglement — multipartite entanglement — via Warren Ellis
Noted physicist Dr Franklin Felber will present his new exact solution of Einstein’s 90-year-old gravitational field equation to the Space Technology and Applications International Forum in Albuquerque. The solution is the first that accounts for masses moving near the speed of light. Felber’s antigravity discovery solves the two greatest engineering challenges to space travel near the speed of light: identifying an energy source capable of producing the acceleration; and limiting stresses on humans and equipment during rapid acceleration — via Warren Ellis
Several companies are developing electronically controlled lenses to provide enhanced vision. Thanks to technologies created for astronomical telescopes and spy satellites, aberrometers can map a person’s eye with extreme accuracy. Lasers bounce off the back of the eyeball, and structures in the eye scatter the resulting beam of light
A team of New York physicists has confirmed that a tabletop contraption made at UCLA does in fact generate nuclear fusion at room temperatures, using pairs of crystals and a small tank of deuterium. But unlike less reliable reports back in the 1980s, there’s no talk this time of producing endless supplies of power. Rather, the technology could lead to ultra-portable x-ray machines and even a wearable device that could provide safe, continuous cancer treatment — via Science Blog
Two antibodies that enabled the severed spinal nerves of rats to be regenerated are to be tested in humans. The antibodies have helped rats with damaged spinal cords to walk again, by blocking the action of Nogo, a protein that stops nerve cells sprouting new connections. But there were concerns about whether blocking Nogo would lead to uncontrolled neuronal rewiring in the brain or spinal cord and it was also unclear how such a therapy could be given to humans
Australian researchers are developing a new surface coating which has the potential to realise the utopian dream of a self-cleaning bathroom. Researchers at the University of NSW are currently testing out a number of properties that might help to create the new coating with the goal of rolling out test products within the next year or so. Their research is based on nanoparticles already being incorporated into self-cleaning glass which comprise a tiny coating of titanium dioxide. When the particles interact with natural light the electrons become activated and oxidate the surface, effectively cleaning it
Egyptian authorities gave a peek Friday into the first tomb uncovered in the Valley of the Kings since 1922. US archaeologists said they discovered the tomb by accident while working on a nearby site. The tomb, believed to be some 3,000 years old and dating to the 18th Dynasty, does not appear to be that of a pharaoh
A team of British scientists investigating whether a tiny tropical hookworm could provide a cure for asthma and hay fever have committed the ultimate act of bravery by infecting themselves with the parasite to observe the effects. It was fairly itchy when they first go through the skin,

Senators have voted in favour of a bill removing control over the abortion drug RU486 from the federal health minister, a noted loonie fundie. Senators were given a rare conscience vote on the bill, with 45 voting in favour of the change and 28 voting against. The bill now heads to the House of Representatives and if passed will end the Health Minister’s power to ban RU486 and allow the Therapeutic Goods Administration to make a decision on the drug. It is the first conscience vote since 2002
Alexander Franklin Mayer, a physicist at Stanford, has just recently published a peer review website for several physics lectures focusing on a single underlying idea that time is not a single dimension of spacetime but rather a local geometric distinction in spacetime. The science is presented quite clearly and originally uses GPS systems as a point of focus — via Slashdot
The US military is considering testing the principle behind a type of space drive which holds the promise of reaching Mars in just three hours. The problem is it’s entirely theoretical and many physicists admit they don’t understand the science behind it — via digg
Fluorinex Active has developed a new technology that can protect the tooth from cavities for five years with one simple electrical treatment. The company is currently working on a small device which, together with a gel, will impose an efficient ion exchange process through an electro-chemical reaction in which fluor ions displace the Hydroxide ions at the outer layer of the tooth. This is intended to produce a new mineral layer with significantly improved chemical and physical resistance to the aggressive bacteria and the resulting acidic environment in the mouth
An astonishing mist-shrouded lost world
of previously unknown and rare animals and plants high in the mountain rainforests of New Guinea has been uncovered by an international team of scientists — via digg
Carbon nanotubes being used to make memory chips. As the name suggests, carbon nanotubes are extremely small cylinders of carbon, and they have some similar properties to the extremely fine hairs on the feet of Geckos that enable the lizards to climb walls and hang from ceilings. The new chips work faster than current technologies, and hold their data without needing a power source
Alon Bodner has developed an underwater breathing system, called LikeAFish, that literally squeezes oxygen directly from seawater, doing away with the need for compressed air tanks — via digg
Suwan Jayasinghe of University College London and colleagues at Kings College London has used a form of ink-jet printing to create

of living cells. The biophysicists say their technique, which does not destroy the cells, could be used to grow biological tissue or even human organs — via digg
Hundreds of thousand of people could die in a nuclear attack, but hundreds of thousands of others could be saved. That’s because the Pentagon — after decades of searching — believes it has found a drug to treat radiation exposure. Why isn’t that drug available? Because bureaucratic red tape is blocking the availability of Neumune, a drug developed by San Diego biotech firm Hollis Eden to treat Acute Radiation Syndrome — via Boing Boing
A study was done where people put on glasses which inverted the image. They saw everything upside-down, but after wearing them constantly for a few days, their brains were retrained to flip the image right-side-up again. When they took the glasses off, the image was upside-down again — via digg
James Hansen, longtime director of the agency’s Goddard Institute for Space Studies and the top climate scientist at NASA, says the Bush administration has tried to stop him from speaking out since he gave a lecture last month calling for prompt reductions in emissions of greenhouse gases linked to global warming — via digg
According to a new UK survey done for the BBC, only 48 percent of Britons accept evolution. Forty-percent of the 2,000 participants think that creationism or intelligent design should be taught in schools — via Boing Boing
