Using Nanotechnology To Build Thinner, Stronger Condoms 253

Hugh Pickens DOT Com writes "Discovery Magazine reports that the Bill and Melinda Gates Foundation has granted $100,000 to Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) to develop a nanoparticle coating for condoms that will make them more comfortable and stronger while simultaneously keeping them thin to preserve – and increase – sensation in order to make them more appealing to use. According to the Gates Foundation, in the time that condoms have been in use, not much has changed: '[Condoms] have undergone very little technological improvement in the past 50 years. The primary improvement has been the use of latex as the primary material and quality-control measures, which allow for quality testing of each individual condom. Material science and our understanding of neurobiology has undergone revolutionary transformation in the last decade, yet that knowledge has not been applied to improve the product attributes of one of the most ubiquitous and potentially underutilized products on earth.' The nanotechnology that the Boston doctors intend to use for their improved condoms will be superhydrophillic nanoparticles that coat the condom and trap water to make them more resilient and easier to use. 'We believe that by altering the mechanical forces experienced by the condom, we may ultimately be able to make a thinner condom which reduces friction, thereby reducing discomfort associated with friction increases pleasure, thereby increasing condom use and decreases rates of unwanted pregnancy and infection transmission.'"

Submission + - Source code for 22nd IOCCC winners has been released (ioccc.org)

An anonymous reader writes: The source code for the 22nd IOCCC winners has finally been released. Many entries exploited bugs in the size check program, making the 2013 entries possibly the most featureful submissions ever.

Submission + - The String Theory Landscape may not be Science after all

StartsWithABang writes: For more than the last decade, physicists have realized that String Theory provides a Landscape of possible values for the cosmological constant, some 10^500 of them. Only the ones that are finely tuned to support possible observers could ever be observed by someone like us, so says the anthropic principle. But despite all the work, publicity and hype that's gone into it, not only have there been no scientific advancements on this front, but this line of thinking is unlikely to ever lead us there, not without some actual science.

Searching the Internet For Evidence of Time Travelers Screenshot-sm 465

Hugh Pickens DOT Com writes "Here's an interesting paper by two physicists at Michigan Technological University who have come up with a practical methodology for finding time travelers through the internet. 'Time travel has captured the public imagination for much of the past century, but little has been done to actually search for time travelers. Here, three implementations of Internet searches for time travelers are described, all seeking a prescient mention of information not previously available. The first search covered prescient content placed on the Internet, highlighted by a comprehensive search for specific terms in tweets on Twitter. The second search examined prescient inquiries submitted to a search engine, highlighted by a comprehensive search for specific search terms submitted to a popular astronomy web site. The third search involved a request for a direct Internet communication, either by email or tweet, pre-dating to the time of the inquiry. Given practical verifiability concerns, only time travelers from the future were investigated. No time travelers were discovered. Although these negative results do not disprove time travel, given the great reach of the Internet, this search is perhaps the most comprehensive to date.' Stephen Hawking's similar search (video) also provided negative results."

4 Tips For Your New Laptop 310

Bennett Haselton writes with four big tips for anyone blessed by the holiday buying frenzy with a new laptop; in particular, these are tips to pass on to non-techie relatives and others who are unlikely to put (say) "Install a Free operating system" at the very top of the list: Here's Bennett's advice, in short: (1) If you don't want to pay for an anti-virus program, at least install a free one. (2) Save files to a folder that is automatically mirrored to the cloud, for effortless backups. (3) Create a non-administrator guest account, in case a friend needs to borrow the computer. (4) Be aware of your computer's System Restore option as a way of fixing mysterious problems that arose recently." Read on for the expanded version; worth keeping in mind before your next friends-and-family tech support call.

CMU AI Learning Common Sense By Watching the Internet 152

An anonymous reader writes with this excerpt from the Washington Post "Researchers are trying to plant a digital seed for artificial intelligence by letting a massive computer system browse millions of pictures and decide for itself what they all mean. The system at Carnegie Mellon University is called NEIL, short for Never Ending Image Learning. In mid-July, it began searching the Internet for images 24/7 and, in tiny steps, is deciding for itself how those images relate to each other. The goal is to recreate what we call common sense — the ability to learn things without being specifically taught."

FCC To Consider Cellphone Use On Planes 183

aitikin writes "The Federal Communications Commission is expected to propose allowing passengers to use their cellphones on airplanes. While phone use would still be restricted during takeoff and landing, the proposal would lift an FCC ban on airborne calls and cellular data use by passengers once a flight reaches 10,000 feet. From the article: 'The move would lift a regulatory hurdle, but any use of cellphones on planes would still have to be approved by the airlines, which have said they would approach the issue cautiously due to strong objections from their customers. Airlines would have to install equipment in their planes that would communicate with cellphone towers on the ground.'"

Ask Slashdot: Can You Trust Online Tax Software? 237

An anonymous reader writes "TurboTax from Intuit and H&R Block's own tax package have been perennial mainstays for U.S. citizens trying to use software to figure out just how much they owe the country, without reading the tens of thousands of pages of IRS forms guidance. With tax season just around the corner, the new online platforms from both providers raise an interesting question: can you trust your return information any more or less to an online platform than you do to the equivalent software on your computer?"
