Paper Microscope Magnifies Objects 2100 Times and Costs Less Than $1

ananyo writes: “If ever a technology were ripe for disruption, it is the microscope. Microscopes are expensive and need to be serviced and maintained. Unfortunately, one important use of them is in poor-world laboratories and clinics, for identifying pathogens, and such places often have small budgets and lack suitably trained technicians. Now Manu Prakash, a bioengineer at Stanford University, has designed a microscope made almost entirely of paper, which is so cheap that the question of servicing it goes out of the window. Individual Foldscopes are printed on A4 sheets of paper (ideally polymer-coated for durability). A pattern of perforations on the sheet marks out the ‘scope’s components, which are colour-coded in a way intended to assist the user in the task of assembly. The Foldscope’s non-paper components, a poppy-seed-sized spherical lens made of borosilicate or corundum, a light-emitting diode (LED), a watch battery, a switch and some copper tape to complete the electrical circuit, are pressed into or bonded onto the paper. (The lenses are actually bits of abrasive grit intended to roll around in tumblers that smooth-off metal parts.) A high-resolution version of this costs less than a dollar, and offers a magnification of up to 2, 100 times and a resolving power of less than a micron. A lower-spec version (up to 400x magnification) costs less than 60 cents.” Read more of this story at Slashdot.

US Takes Out Gang That Used Zeus Malware To Steal Millions

coondoggie (973519) writes “The US Department of Justice charged nine members of a group that used Zeus malware to infect thousands of business computers and illegally siphon-off millions of dollars into over-seas bank accounts. The DoJ said an indictment was unsealed in connection with the arraignment this week at the federal courthouse in Lincoln, Neb., of two Ukrainian nationals, Yuriy Konovalenko, 31, and Yevhen Kulibaba, 36. Konovalenko and Kulibaba were recently extradited from the United Kingdom.” Read more of this story at Slashdot.

$250K Reward Offered In California Power Grid Attack

An anonymous reader writes “The Associated Press reports that Pacific Gas & Electric Co. has put up a $250, 000 reward for ‘information leading to an arrest and conviction in a startling attack mounted nearly a year ago on telephone lines and the power grid in Silicon Valley.’ Besides cutting power lines, the attackers also cut AT&T fiber-optic phone lines, thereby denying some people access to 911, and fired shots into a PB&E substation, knocking out 17 transformers in Silicon Valley and causing $15 million in damage. As of this post, the perpetrators are still unidentified and continue to elude the FBI. Meanwhile, the Federal Energy Regulatory Commission (FERC) on Thursday was brought before the Senate Energy Committee to explain why the FERC disseminated via insecure media a sensitive document describing where all the nation’s power grids are particularly sensitive to a physical attack. FERC responded with assurances that databases are currently being scrubbed and procedures being implemented to safeguard critical data.” Read more of this story at Slashdot.

New French Law Prohibits After-Hours Work Emails

Hugh Pickens DOT Com (2995471) writes “Lucy Mangan reports at The Guardian that a new labor agreement in France means that employees must ignore their bosses’ work emails once they are out of the office and relaxing at home – even on their smartphones. Under the deal, which affects a million employees in the technology and consultancy sectors (including the French arms of Google, Facebook, and Deloitte), employees will also have to resist the temptation to look at work-related material on their computers or smartphones – or any other kind of malevolent intrusion into the time they have been nationally mandated to spend on whatever the French call la dolce vita. “We must also measure digital working time, ” says Michel De La Force, chairman of the General Confederation of Managers. “We can admit extra work in exceptional circumstances but we must always come back to what is normal, which is to unplug, to stop being permanently at work.” However critics say it will impose further red tape on French businesses, which already face some of the world’s tightest labor laws.” (Continues) Read more of this story at Slashdot.

Navy Creates Fuel From Seawater

New submitter lashicd sends news that the U.S. Naval Research Laboratory has announced a successful proof-of-concept demonstration of converting seawater to liquid hydrocarbon fuel. They used seawater to provide fuel for a small replica plan running a two-stroke internal combustion engine. “Using an innovative and proprietary NRL electrolytic cation exchange module (E-CEM), both dissolved and bound CO2 are removed from seawater at 92 percent efficiency by re-equilibrating carbonate and bicarbonate to CO2 and simultaneously producing H2. The gases are then converted to liquid hydrocarbons by a metal catalyst in a reactor system. … NRL has made significant advances in the development of a gas-to-liquids (GTL) synthesis process to convert CO2 and H2 from seawater to a fuel-like fraction of C9-C16 molecules. In the first patented step, an iron-based catalyst has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production in favor of longer-chain unsaturated hydrocarbons (olefins). These value-added hydrocarbons from this process serve as building blocks for the production of industrial chemicals and designer fuels.” Read more of this story at Slashdot.

Samsung Claims Breakthrough In Graphene Chip Design

jfruh (300774) writes “Graphene, a carbon-based crystalline lattice that is extremely strong, lightweight, and an excellent conductor of electricity and heat, is coveted as a potential base for semiconductor chip design, and Samsung, working with the Sungkyungkwan University School of Advanced Materials Science and Engineering, has claimed a big jump towards that goal. With IBM also making progress in this realm, the days of silicon could actually be numbered.” Read more of this story at Slashdot.

Nanodot-Based Smartphone Battery Recharges In 30 Seconds

Zothecula (1870348) writes “At Microsoft’s Think Next symposium in Tel Aviv, Israeli startup StoreDot has demonstrated the prototype of a nanodot-based smartphone battery it claims can fully charge in just under 30 seconds. With the company having plans for mass production, this technology could change the way we interact with portable electronics, and perhaps even help realize the dream of a fast-charging electric car.” Read more of this story at Slashdot.

Microsoft’s Security Products Will Block Adware By Default Starting On July 1

An anonymous reader writes “Microsoft [Thursday] announced a change to how it handles adware, a form of malware that pushes unwanted advertisements to the user. As of July 1, the company’s security products will immediately stop any adware they detect and notify the user, who can then restore the program if they wish. Currently, when any of Microsoft’s security products (including Microsoft Security Essentials and Microsoft Forefront) detects a program as adware, it will alert the user and offer them a recommended action. If the user doesn’t do anything, the security product will let the program continue to run until the user makes a decision.” If adware is malware, why wait until July?
