An anonymous reader writes: License plate scanners are a contentious subject, generating lots of debate over what information the government should have, how long they should have it, and what they should do with it. However, it seems policy changes are driven more by practical matters than privacy concerns. Earlier this year, Ars Technica reported that the Oakland Police Department retained millions of records going back to 2010. Now, the department has implemented a six-month retention window, with older data being thrown out. Why the change? They filled up the 80GB hard drive on the Windows XP desktop that hosted the data, and it kept crashing. Why not just buy a cheap drive with an order of magnitude more storage space? Sgt. Dave Burke said, "We don't just buy stuff from Amazon as you suggested. You have to go to a source, i.e., HP or any reputable source where the city has a contract. And there's a purchase order that has to be submitted, and there has to be money in the budget. W ...
HughPickens.com writes: A police officer is directing traffic in the intersection when he sees a self-driving car barreling toward him and the occupant looking down at his smartphone. The officer gestures for the car to stop, and the self-driving vehicle rolls to a halt behind the crosswalk. This seems like a pretty plausible interaction. Human drivers are required to pull over when a police officer gestures for them to do so. It's reasonable to expect that self-driving cars would do the same. But Will Oremus writes that while it's clear that police officers should have some power over the movements of self-driving cars, what's less clear is where to draw the line. Should an officer be able to do the same if he suspects the passenger of a crime? And what if the passenger doesn't want the car to stop—can she override the command, or does the police officer have ultimate control? According to a RAND Corp. report on the future of technology and law enforcement "the dark side to all ...
iONiUM sends news that Mayo Clinic cancer researchers have developed a technique to reprogram cancer cells in a lab, essentially "turning off" their excessive cell growth.That code was unraveled by the discovery that adhesion proteins — the glue that keeps cells together — interact with the microprocessor, a key player in the production of molecules called microRNAs (miRNAs). The miRNAs orchestrate whole cellular programs by simultaneously regulating expression of a group of genes (abstract). The investigators found that when normal cells come in contact with each other, a specific subset of miRNAs suppresses genes that promote cell growth. However, when adhesion is disrupted in cancer cells, these miRNAs are misregulated and cells grow out of control. The investigators showed, in laboratory experiments, that restoring the normal miRNA levels in cancer cells can reverse that aberrant cell growth. Read more of this story at Slashdot.
theodp writes: Wired positively gushes over IBM's Pathways in Technology Early College High School (P-TECH), saying it could fix education and tech's diversity gap. Backed by IBM, the P-TECH program aims to prepare mainly minority kids from low-income backgrounds for careers in technology, allowing them to earn a high school diploma and a free associate degree in six years or less. That P-TECH's six inaugural graduates completed the program in four years and were offered jobs with IBM, Wired reports, is "irrefutable proof that this solution might actually work" (others aren't as impressed, although the President is drinking the Kool-Aid). While the program has only actually graduated six students since it was announced in 2010, Wired notes that by fall, 40 schools across the country will be designed in P-TECH's image. IBM backs four of them, but they'll also be run by tech giants like Microsoft and SAP, major energy companies like ConEdison, along with hospital systems, manufacturing a ...
sciencehabit writes: Articles with shorter titles tend to get cited more often than those with longer headers, concludes a study published today, which examined 140,000 papers published between 2007 and 2013. It appears in the journal Royal Society Open Science. Citations are a key currency in the academic world. The number of times other researchers cite a scientist’s work is often an important metric in hiring and workplace evaluations. Citations also play a role in determining a journal’s place in the scholarly pecking order, with journals that publish more highly cited papers earning a higher “impact factor” (although many critics challenge that measure).

Lucas123 writes: Researchers at MIT have been able to build a printer with uses 10 different photosensitive polymers to create a myriad of objects, and they were able to build it using off-the-shelf commodity parts for around $7,000. The MultiFab 3D printer works by mixing together microscopic droplets of photopolymers that are then extruded through inkjet printheads similar to those in office printers. A UV light then hardens the polymers layer by layer. Perhaps even more remarkable than the list of materials it can use is the MultiFab 3D printer's ability to self-calibrate and self-correct during a print job (PDF). The printer has an integrated machine vision system that automatically readjusts the printer head if errors occur, rectifying the build before a problem ruins the object; that means print jobs that run into errors don't need to be cancelled and materials wasted. The researchers said they can foresee an array of applications for the MultiFab 3D in consumer electronics, micr ...
szczys writes: Crowd Funding is the wild-wild west of business financing, and it's not just the people starting campaigns that are playing without many rules. One of Kickstarter's sort algorithm triggers is the "Staff Pick." Research indicates being featured by Kickstarter staff is a huge predictor for success. But there is no published benchmark for how these are chosen. Oddly, Kickstarter only discourages users from falsely labeling their campaign as a Staff Pick. To protect backers and ensure the crowdfunding ecosystem isn't sullied by scammers, Kickstarter needs to boost their transparency starting with this Staff Pick conundrum.

HughPickens.com writes: In the mid-1980s, a University of Arizona surgery professor, Marlys H. Witte, proposed teaching a class entitled "Introduction to Medical and Other Ignorance." Far too often, she believed, teachers fail to emphasize how much about a given topic is unknown. "Textbooks spend 8 to 10 pages on pancreatic cancer," said Witte, "without ever telling the student that we just don't know very much about it." Now Jamie Holmes writes in the NY Times that many scientific facts simply aren't solid and immutable, but are instead destined to be vigorously challenged and revised by successive generations. According to Homes, presenting ignorance as less extensive than it is, knowledge as more solid and more stable, and discovery as neater also leads students to misunderstand the interplay between answers and questions. In 2006, a Columbia University neuroscientist named Stuart J. Firestein, began teaching a course on scientific ignorance after realizing, to his horror, that many ...
New submitter subh_arya writes: Engineers from Microsoft Research have unveiled the first technology to perform 3D surface reconstruction from ordinary smartphone cameras. Their computational framework creates a connected 3D surface model by continuously registering RGB input to an incrementally built 3D model. Although the reconstruction results look promising, Microsoft does not plan to release an app anytime soon. Read more of this story at Slashdot.
