Rare US total solar eclipse excites Americans coast-to-coast For the first time in almost a century the United States is preparing for a coast-to-coast solar eclipse, a rare celestial event millions of Americans, with caution, will be able to observe.
Institute of Nanotechnology Small world by Ralph C. Merkle Xerox PARC 3333 Coyote Hill Road Palo Alto, CA 94304 merkle@xerox.com This is an extended web version of the article published in the Feb/Mar 1997 issue of MIT Technology Review. This version has greater technical detail and embedded links. Introduction Manufactured products are made from atoms. Since we first made stone tools and flint knives we have been arranging atoms in great thundering statistical heards by casting, milling, grinding, chipping and the like. That's changing. Build products with almost every atom in the right place. One warning: in contrast to the useage in this article some researchers use the word "nanotechnology" to refer to high resolution lithographic technology while others use it to refer to almost any research where some critical size is less than a micron (1,000 nanometers). There are two main issues in nanotechnology: What might molecular manufacturing systems look like? The advantages ofnanotechnology The advantages of positional control
This article discusses the extensive range of nano tech 2012 International Nanotechnology Exhibition & Conference 11 Predictions for the World in 2030 That May Sound Outrageous Today but not in the Future. - I Look Forward To All futurism is speculation. It's time someone made some claims. I've picked developments I honestly consider plausible. Alright, crystal ball time: 1. A tiny computer that fits in your ear, and translates what you hear into your own language? 2. Aubrey de Grey says: I think we have a 50% chance of achieving medicine capable of getting people to 200 in the decade 2030-2040. 3. The eradication of extreme poverty will happen in our lifetime. 4. Soil-based agriculture is so passé. 5. I'm sure you've dreamed it: Getting into a car, kicking your shoes off and leaning back with a good movie and a cold beer while your self-driven car takes you safely to your destination, without your having to worry about directions or pedestrians. 6. I actually think this is a conservative estimate. 7. Probably a lot sooner, actually. 8. 9. 10. Today, 90% of people in the UK and 80% of Americans live in cities, while in China only 46% do. 11.

Overview of Nanotechnology Nanotechnology draws its name from the prefix "nano". A nanometer is one-billionth of a meter—a distance equal to two to twenty atoms (depending on what type of atom) laid down next to each other. Nanotechnology refers to manipulating the structure of matter on a length scale of some small number of nanometers, interpreted by different people at different times as meaning anything from 0.1 nm (controlling the arrangement of individual atoms) to 100 nm or more (anything smaller than microtechnology). At the small end of this scale, the structure is controlled to atomic precision—each atom is exactly where it should be for the optimum function of the material or the device. The Foresight Institute is focused on this small end of the scale: atomically-precise manufacturing or "molecular manufacturing". Life is the Existence Proof for Atomically Precise Technology Chemistry has of course always worked with atomic precision. Building to Atomic Precision
Tiny brains created from SKIN could lead to cures for disorders like schizophrenia and autism Scientists used stem cells to grow 3D tissue that mimics a brainThe cells displayed an organisation similar to that seen in the early stages of the developing human brain's cerebral cortex - also known as grey matterThe miniature brains helped the researchers identify a defect that affects normal brain development in microcephaly leading to a smaller brainThe findings could eventually lead to treatments for other neurological disorders By Emma Innes Published: 18:19 GMT, 28 August 2013 | Updated: 00:00 GMT, 29 August 2013 A ‘brain in a bottle’ has been grown by stem cell scientists who hope it will lead to treatments for neurological and mental diseases. The ‘organoids’, three to four millimetres across, have a structure similar to that of an immature human brain. The goal was to produce a biological tool that can be used to investigate the workings of the brain, better understand brain diseases, and test new drugs. ‘These structures are not just peculiar lab artefacts.
'Fabbers' could launch a revolution Lindsay France/University Photography Hod Lipson, assistant professor of mechanical and aerospace engineering, right, and engineering graduate student Evan Malone work with a Fab@Home machine in the Computational Synthesis Lab in Upson Hall Feb. 22. On the stage is a Lego tire duplicated by the Fab@Home. The Altair 8800, introduced in the early 1970s, was the first computer you could build at home from a kit. Hod Lipson, Cornell assistant professor of mechanical and aerospace engineering, thinks a little machine he calls a Fab@Home may have the same impact. Some day, Lipson believes, every home will have a "fabber," a machine that replicates objects from plans supplied by a computer. Such machines could evolve from the 3-D printers currently used by industrial engineers for "rapid prototyping." Lindsay France/U. "Fabbing" a Lego tire. Provided The Lego tire on the vehicle. Some recent developments: A high school student in Kentucky is "fabbing" chocolate bars.
News ::: Columbia Engineers Prove Graphene is Strongest Material July 21, 2008 Columbia Engineers Prove Graphene is the Strongest Material Research scientists at Columbia University’s Fu Foundation School of Engineering and Applied Science have achieved a breakthrough by proving that the carbon material graphene is the strongest material ever measured. Graphene holds great promise for the development of nano-scale devices and equipment. Until now, graphene’s estimated strength, elasticity and breaking point were based on complex computer modeling theories. “Our team sidestepped the size issue by creating samples small enough to be defect-free,” said Columbia Professor Jeffrey Kysar. The studies were conducted by postdoctoral researcher Changgu Lee and graduate student Xiaoding Wei, in the research groups of mechanical engineering professors Kysar and James Hone. “Our research establishes graphene as the strongest material ever measured, some 200 times stronger than structural steel,” Hone said.
