someWebGeek writes "From PhysOrg's 'Taking biofuel from forest to highway,' University of British Columbia biofuel expert Jack Saddler says, 'we will become less dependent on fossil fuels and will become more dependent on fuels made from the sugars and chemicals found in plants.' Nothing too new there; the idea of biofuels eventually taking over from petroleum distillates has been around for ages. However, Saddler contends further that 'Similar to an oil refinery that processes crude oil to make thousands of supplementary products like plastics, dyes, paints, etc., the biorefinery would use leftover agricultural and forest material to make many of the same products, but from a sustainable and renewable resource.' I remember my organic chem instructor back in '81 telling us that eventually the textbooks would have to be rewritten. There would be no presumption of fractional distillation of thousands of basic compounds from petroleum, and the teaching emphasis would shift to synthesis from simple hydrocarbons. He noted that we'd all miss 'the good, ole days' when synthetic fibers, plastics, etc. were cheap... or even an economically viable option. I can live without rayon, but, dang, I'm gonna miss polyvinyl chloride!"
Zothecula writes "Oxford Nanopore has been developing a disruptive nanopore-based technology for sequencing DNA, RNA, proteins, and other long-chain molecules since its birth in 2005. The company has just announced that within the next 6-9 months it will bring to market a fast, portable, and disposable protein sequencer that will democratize sequencing by eliminating large capital costs associated with equipment required to enter the field."
redletterdave writes "Samsung Electronics announced Monday that it will spin off its LCD business division to launch a new entity, provisionally called Samsung Display Co., set to go live on April 1, 2012. The new business will launch with about $668 million in capital, but Samsung plans to invest about $5.8 billion in 2012 to develop better displays. The move, which now awaits shareholder approval, has been rumored for months since Samsung's LCD business announced operating losses of $666 million in 2011, citing sluggish TV sales. The company's spin-off display business may eventually merge with Samsung Mobile Display, which makes the company's organic light-emitting diode (OLED) panels that are currently in high demand."
angry tapir writes "Intel's experimental solar-powered processor may have started off as a fun project, but the chip maker is now looking to extend the technology to hardware such as graphics processors, memory and floating point units. Intel last year showed the low-power processor — charged only by the light from a reading lamp — running Windows and Linux PCs. Intel is expected to share further details about the processor, which is code-named Claremont, at the International Solid-State Circuits Conference in San Francisco. The company is also expected to reveal information about efforts to integrate wireless capabilities into Atom chips for mobile devices."
Lucas123 writes "New research shows that far more than wireless network or CPUs, the NAND flash memory in cell phones, and in particular smartphones, affects the device's performance when it comes to loading apps, surfing the web and loading and reading documents. In tests with top-selling 16GB smartphones, NAND flash memory slowed mobile app performance from two to three times with one exception, Kingston's embedded memory card; that card slowed app performance 20X. At the bottom of the bottleneck is the fact that while network and CPUs speeds have kept pace with mobile app development, flash throughput hasn't. The researchers from Georgia Tech and NEC Corp. are working on methods to improve flash performance (PDF), including using a PRAM buffer to stage writes or be used as the final location for the SQLite databases."
Barence writes "In 2006, AMD could seemingly do no wrong. Its processors were the fastest in the PC market, annual revenue was up a record 91%, expansion into the graphics game had begun with the high-profile acquisition of ATI, and it was making exciting plans for a future where it looked like it could 'smash Intel's chip monopoly' for good. Now the company is fighting for its very survival. How did AMD end up surrendering such a advantageous position – and was it given an unfair shove on the way down? This article has plotted AMD's decline, including the botched processor launches, the anti-competitive attacks from Intel and years of boardroom unrest."
New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.
bonch writes "After months of reporting on photos of iPad 3 screen parts, MacRumors finally obtained one for themselves and examined it under a microscope, confirming that the new screens will have twice the linear resolution of the iPad 2, with a whopping 2048x1536 pixel density. Hints of the new display's resolution were found in iBooks 2, which contains hi-DPI versions of its artwork. The iPad 3 is rumored to be launching in early March."
First time accepted submitter core_tripper writes "Students at the University of Twente have stolen thirty laptops from various members of the university's staff. They were not prosecuted for this, so they could just get on with their studies. Indeed, these students even received ECTS credits for these thefts. UT researcher Trajce Dimkov asked the students to steal the machines as part of a scientific experiment. Stealing these laptops turned out to be a pretty simple matter."
MojoKid writes "OpenXC is an open source connectivity platform developed in tandem by Ford and open source hardware maker Bug Labs. Announced this fall, the platform is designed to allow developers the ability to use Android- and Arduino-based modules to interact with a vehicle's in-car tech, such as vehicle sensors and GPS units. The OpenXC website succinctly describes the platform as 'an API to your car.' Ford announced that OpenXC beta test kits are now shipping to developers worldwide, including U.S. institutions such as MIT and Standford as well as India's HCL Technologies."
New submitter jank1887 writes "Back in 2010, the aid organization Climate Healers gave a number of solar-powered cookstoves to rural Indian villages. The stoves were rejected by the communities, mainly because they were useless when they were wanted most: for the evening meal sometimes after the sun goes down, and for breakfast before the sun has risen. Following this, the group issued a challenge to EngineeringForChange. Details of the challenge include the need to provide 1kW of heat at about 200C for two hours in both early morning and late evening, and the users should be able to cook indoors, while sitting. A number of groups, mainly at U.S. and Indian engineering institutions, accepted the challenge, and developed potential solutions. Now, almost a year later, the ten finalist designs have been selected. The actual papers have been posted to the E4C challenge workspace. The goals of most of the designs are to keep the technology simple, although there are a few exceptions, and many include sand-, oil-, and salt-based concentrated thermal storage. Many reports include some level of discussion on the social and economic considerations, barriers to acceptance and sustainability, and how to overcome initial resistance to adoption."
cylonlover writes "This year is a historic one for nuclear power, with the first reactors winning U.S. government approval for construction since 1978. Some have seen the green lighting of two Westinghouse AP1000 reactors to be built in Georgia as the start of a revival of nuclear power in the West, but this may be a false dawn because of the problems besetting conventional reactors. It may be that when a new boom in nuclear power comes, it won't be led by giant gigawatt installations, but by batteries of small modular reactors (SMRs) with very different principles from those of previous generations. However, while it's a technology of great diversity and potential, many obstacles stand in its path. This article takes an in-depth look at the many forms of SMRs, their advantages, and the challenges they must overcome."
ananyo writes "DNA origami, a technique for making structures from DNA, has been used to build devices that can seek out and potentially destroy cancer cells. The nanorobots use a similar system to cells in the immune system to engage with receptors on the outside of cells. The barrel-shaped devices, each about 35 nanometers in diameter, contain 12 sites on the inside for attaching payload molecules and two positions on the outside for attaching aptamers, short nucleotide strands with special sequences for recognizing molecules on the target cell (abstract). The aptamers act as clasps: once both have found their target, they spring open the device to release the payload. The researchers tested six combinations of aptamer locks, each of which were designed to target different types of cancer cells in culture. Those designed to hit a leukemia cell could pick that cell out of a mixture of cell types, then release their payload — in this case, an antibody — to stop the cells from growing. The researchers designed the structure of the nanorobots using open-source software, called Cadnano."
Zothecula writes "Inspired by origami and children's pop-up books, Harvard engineers have pioneered a means of mass-producing bee-sized flying microrobots. The breakthrough mechanizes the already state-of-the art process of making Harvard's Mobee robots by hand, by mass producing flat assemblies by the sheet which can be folded and assembled in a single movement. The technique, which cunningly exploits existing machinery for making printed circuit boards, can theoretically be applied to a multitude of electromechanical machines."
An anonymous reader writes "The idea is simple — load up a microchip with a whole pharmacy of drugs that are dispensed as needed automatically. The devil has been in the details, since mistakes could kill the patient if, say, a leak developed dumping dangerous cocktails into the bloodstream. This MIT sponsored company, however, claims to have perfected wireless control of a pharmacy-on-a-chip and has just completed the clinical trials to prove it. The test microchip has just 20 doses of a single drug, but their new prototype will house thousands of pin-prick sized drug reservoirs, after which they will seek FDA approval. The elderly (who have complicated drug regime) and soldiers could both benefit from these smart pharmacies-on-a-chip, since drugs can be dispensed even if the patient is unconscious."
