British company claims biggest engine advance since the jet
intellitech (1912116) writes "Excerpts from the article: "A small British company, Reaction Engines Ltd, believes its Sabre engine, which would operate like a jet engine in the atmosphere and a rocket in space, could displace rockets for space access and transform air travel by bringing any destination on Earth to no more than four hours away. Sabre produces thrust by burning hydrogen and oxygen, but inside the atmosphere it would take that oxygen from the air, reducing the amount it would have to carry in fuel tanks for rocket mode, cutting weight and allowing Skylon to go into orbit in one stage. Scramjets on test vehicles like the U.S. Air Force Waverider also use atmospheric air to create thrust but they have to be accelerated to their operating speed by normal jet engines or rockets before they kick in. The Sabre engine, however, can operate from a standing start. If the developers are successful, Sabre would also be the first engine in history to send a vehicle into space without using disposable, multi-stage rockets. The space plane to incorporate this engine, dubbed Skylon, only exists on paper. What the company has right now is a remarkable heat exchanger that is able to cool air sucked into the engine at high speed from 1,000 degrees Celsius to minus 150 degrees in one hundredth of a second. However, they are tight-lipped on exactly how they managed to do it. The company has deliberately avoided filing patents on its heat exchanger technology to avoid details of how it works — particularly the method for preventing the build-up of frost — becoming public.""

New Comet Discovered—May Become "One of Brightest in History"
intellitech writes "Puzzling results from Cern, home of the LHC, have confounded physicists — because it appears subatomic particles have exceeded the speed of light. Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away seemed to show up a few billionths of a second early. The results will soon be online to draw closer scrutiny to a result that, if true, would upend a century of physics. The lab's research director called it "an apparently unbelievable result"."

intellitech (1912116) writes "From the article: The amount of debris orbiting the Earth has reached a tipping point for collisions, which would in turn generate more debris which threatens astronauts and satellites, according to a U.S. study released on Thursday. "The current space environment is growing increasingly hazardous to spacecraft and astronauts," Donald Kessler, the former head of NASA's Orbital Debris Program Office who chaired the study team, said in a statement. In addition to more than 30 findings, the panel made two dozen recommendations for NASA to mitigate and improve the orbital debris environment, including collaborating with the State Department to develop the legal and regulatory framework for removing junk from space. The study, "Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Programs," was sponsored by NASA." Link to Original Source top
intellitech (1912116) writes "Researchers led by ETH professor Yaakov Benenson and MIT professor Ron Weiss have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction. In a study that has just been published in Science (abstract), they describe a multi-gene synthetic "circuit" whose task is to distinguish between cancer and healthy cells and subsequently target cancer cells for destruction. This circuit works by sampling and integrating five intracellular cancer-specific molecular factors and their concentration. The circuit makes a positive identification only when all factors are present in the cell, resulting in a highly precise cancer detection. Researchers hope that it can serve a basis for very specific anti-cancer treatments." Link to Original Source top
intellitech (1912116) writes "Using state-of-the-art theoretical computations, the University of Kentucky-University of Louisville team demonstrated that an alloy formed by a 2 percent substitution of antimony (Sb) in gallium nitride (GaN) has the right electrical properties to enable solar light energy to split water molecules into hydrogen and oxygen, a process known as photoelectrochemical (PEC) water splitting. When the alloy is immersed in water and exposed to sunlight, the chemical bond between the hydrogen and oxygen molecules in water is broken. Because pure hydrogen gas is not found in free abundance on Earth, it must be manufactured by unlocking it from other compounds. Thus, hydrogen is not considered an energy source, but rather an "energy carrier." Currently, it takes a large amount of electricity to generate hydrogen by water splitting. As a consequence, most of the hydrogen manufactured today is derived from non-renewable sources such as coal and natural gas. The team says the GaN-Sb alloy has the potential to convert solar energy into an economical, carbon-free source for hydrogen." Link to Original Source top
intellitech (1912116) writes "The underlying disease process of amyotrophic lateral sclerosis (ALS and Lou Gehrig's disease), a fatal neurodegenerative disease that paralyzes its victims, has long eluded scientists and prevented development of effective therapies. Scientists weren't even sure all its forms actually converged into a common disease process, but a new Northwestern Medicine study has identified a common cause of all forms of ALS for the first time. The basis of the disorder is a broken down protein recycling system in the neurons of the spinal cord and the brain. Optimal functioning of the neurons relies on efficient recycling of the protein building blocks in the cells. In ALS, that recycling system is broken. The cell can't repair or maintain itself and becomes severely damaged. The discovery by Northwestern University Feinberg School of Medicine researchers, published in the journal Nature, provides a common target for drug therapy and shows that all types of ALS are, indeed, tributaries, pouring into a common river of cellular incompetence."

intellitech (1912116) writes "In the 15th century, when Europeans first began moving people and goods across the Atlantic, a microscopic stowaway somehow made its way to the caves and monasteries of Bavaria. The stowaway, a species of yeast that may have been transported from a distant shore on a piece of wood or in the stomach of a fruit fly, was destined for great things. In the dank caves and monastery cellars where 15th century brewmeisters stored their product, the newly arrived yeast fused with a distant relative, the domesticated yeast — used for millennia to make leavened bread and ferment wine and ale. The resulting hybrid, representing a marriage of species as evolutionarily separated as humans and chickens, would give us lager — the clear, cold-fermented beer first brewed by 15th century Bavarians and that today is among the most popular, if not the most popular, alcoholic beverage in the world."

Ultra-Fast Magnetic Reversal To Speed Up ReadWrite

The microscopic apparatus is a new tool for processing information and potentially could control the motion of a relatively large object at the smallest possible, or quantum, scale."

This could be expected from a country like China or the former Soviet Union, but there is simply no legitimate justification for such actions in the United States of America, unless our government is now attempting to mimic authoritarian regimes, which seems very much to be the case."
