Stem Cells Grown From Patient's Arm Used To Replace Retina

Slashdot - 1 hour 50 min ago
BarbaraHudson writes: The Globe and Mail is reporting the success of a procedure to implant a replacement retina grown from cells from the patient's skin. Quoting: "Transplant doctors are stepping gingerly into a new world, one month after a Japanese woman received the first-ever tissue transplant using stem cells that came from her own skin, not an embryo. On Sept. 12, doctors in a Kobe hospital replaced the retina of a 70-year-old woman suffering from macular degeneration, the leading cause of blindness in the developed world. The otherwise routine surgery was radical because scientists had grown the replacement retina in a petri dish, using skin scraped from the patient's arm. The Japanese woman is fine and her retinal implant remains in place. Researchers around the world are now hoping to test other stem-cell-derived tissues in therapy. Dr. Jeanne Loring from the Scripps Research Institute in La Jolla, Calif., expects to get approval within a few years to see whether neurons derived from stem cells can be used to treat Parkinson's disease."

Detritus From Cancer Cells May Infect Healthy Cells

Slashdot - 2 hours 33 min ago
bmahersciwriter writes Tiny bubbles of cell membrane — called exosomes — are shed by most cells. Long thought to be mere trash, researchers had recently noticed that they often contain short, regulatory RNA molecules, suggesting that exosomes may be one way that cells communicate with one another. Now, it appears that RNA in the exosomes shed by tumor cells can get into healthy cells and 'transform' them, putting them on the path to becoming cancerous themselves.

British Army Looking For Gamers For Their Smart-Tanks

Slashdot - 5 hours 11 min ago
concertina226 writes The U.K. branch of global defense firm General Dynamics is working on a futuristic state-of-the-art smart-tank to replace the British Army's aging armored vehicle fleet, to be delivered to the Ministry of Defense in 2020. The Scout SV armored vehicle is the first fully-digitized armored fighting vehicle to have been built for the British Army, and is far bigger and more durable than any of its existing tanks, which are now at least 20 years old. The tank comes in six variants that can be customized with a tools for different missions, and has numerous sensors, cameras, and sights to offer real-time intelligence on weather conditions, target acquisition, and reconnaissance — all crucial battlefield data required by commanders to access and direct situations. "With the capability in the Scout SV, we're really looking for the type of people who play Xbox games – tech-savvy people who are able to take in a lot of information and process it in the proper way," says Kevin Connell, the vice president for General Dynamic UK's Land Systems Regiment.

Incapacitating Chemical Agents: Coming Soon To Local Law Enforcement?

Slashdot - 7 hours 6 min ago
Lasrick writes To this day, Russian authorities refuse to disclose the incapacitating chemical agent (ICA) they employed in their attempt, 12 years ago, to save 900 hostages held in a theater by Chechen fighters. Malcom Dando elaborates on a new report (PDF) that Russia, China, Israel, and a slew of other countries are continuing research into ICAs, and the apparent indifference of the international community into such research. Proponents of ICAs have long promoted their use in a variety of scenarios, including that of law enforcement, because in theory these chemicals incapacitate without permanent disability. Critics, however, point out that these weapons rely on exact dosage to prevent fatality, and that the ability to 'deliver the right agent to the right people in the right dose without exposing the wrong people, or delivering the wrong dose' is a near-impossible expectation. ICAs represent the further misuse and militarization of the life sciences and a weakening of the taboo against the weaponization of toxic substances, and the idea that they could be used in law enforcement situations is a disturbing one."

An anonymous reader writes A small group of researchers were able to publish an investigative report on the hacking of a popular Bitcoin exchange earlier this year by the name of CryptoRush.in. Close to a million dollars stolen in crypto currency lead the group to discover evidence, track down the attacker and put together a timeline of what exactly happened. A captivating read for a community desensitized by thefts, hackings and lack of reporting. With pictures, and logs to prove it all.

How Sony, Intel, and Unix Made Apple's Mac a PC Competitor

Slashdot - 13 hours 30 min ago
smaxp writes In 2007, Sony's supply chain lessons, the network effect from the shift to Intel architecture, and a better OS X for developers combined to renew the Mac's growth. The network effects of the Microsoft Wintel ecosystem that Rappaport explained 20 years ago in the Harvard Business Review are no longer a big advantage. By turning itself into a premium PC company with a proprietary OS, Apple has taken the best of PC ecosystem, but avoided taking on the disadvantages.

Microsoft Exec Opens Up About Research Lab Closure, Layoffs

Slashdot - 15 hours 12 min ago
alphadogg writes It's been a bit over a month since Microsoft shuttered its Microsoft Research lab in Silicon Valley as part of the company's broader restructuring that will include 18,000 layoffs. This week, Harry Shum, Microsoft EVP of Technology & Research, posted what he termed an "open letter to the academic research community" on the company's research blog. In the post, Shum is suitably contrite about the painful job cut decisions that were made in closing the lab, which opened in 2001. He also stresses that Microsoft will continue to invest in and value "fundamental research".

Tech Firm Fined For Paying Imported Workers $1.21 Per Hour

Slashdot - 15 hours 56 min ago
An anonymous reader sends in news about a company that was fined for flying in "about eight employees" from India to work 120-hour weeks for $1.21 per hour. Electronics for Imaging paid several employees from India as little as $1.21 an hour to help install computer systems at the company's Fremont headquarters, federal labor officials said Wednesday. "We are not going to tolerate this kind of behavior from employers," said Susana Blanco, district director of the U.S. Labor Department's wage and hour division in San Francisco.... An anonymous tip prompted the U.S. Department of Labor to investigate the case, which resulted in more than $40,000 in back wages paid to the eight employees and a fine of $3,500 for Electronics for Imaging.

Mark Zuckerberg Speaks Mandarin At Tsinghua University In Beijing

Slashdot - 16 hours 40 min ago
HughPickens.com writes Abby Phillip reports at the Washington Post that that Mark Zuckerberg just posted a 30-minute Q&A at Tsinghua University in Beijing in which he answered every question exclusively in Chinese — a notoriously difficult language to learn and particularly, to speak. "It isn't just Zuckerberg's linguistic acrobatics that make this a notable moment," writes Philip. "This small gesture — although some would argue that it is a huge moment — is perhaps his strongest foray into the battle for hearts and minds in China." Zuckerberg and Facebook have been aggressively courting Chinese users for years and the potential financial upside for the business. Although Beijing has mostly banned Facebook, the company signed a contract for its first ever office in China earlier this year. A Westerner speaking Mandarin in China — at any level — tends to elicit joy from average Chinese, who seem to appreciate the effort and respect they feel learning Mandarin demonstrates. So how well did he actually do? One Mandarin speaker rates Zuckerberg's language skills at a seventh grader's speech: "It's hard not see a patronizing note in the Chinese audience's reaction to Zuckerberg's Mandarin. To borrow from Samuel Johnson's quip, he was like a dog walking on its hind legs: It wasn't done well, but it was a surprise to see it done at all."

Assange: Google Is Not What It Seems

Slashdot - Thu, 10/23/2014 - 23:15
oxide7 (1013325) writes "In June 2011, Julian Assange received an unusual visitor: the chairman of Google, Eric Schmidt. They outlined radically opposing perspectives: for Assange, the liberating power of the Internet is based on its freedom and statelessness. For Schmidt, emancipation is at one with U.S. foreign policy objectives and is driven by connecting non-Western countries to Western companies and markets. These differences embodied a tug-of-war over the Internet's future that has only gathered force subsequently. Assange describes his encounter with Schmidt and how he came to conclude that it was far from an innocent exchange of views."

Leaked Documents Reveal Behind-the-Scenes Ebola Vaccine Issues

Slashdot - Thu, 10/23/2014 - 22:33
sciencehabit writes Extensive background documents from a meeting that took place today at the World Health Organization (WHO) have provided new details about exactly what it will take to test, produce, and bankroll Ebola vaccines, which could be a potential game changer in the epidemic. ScienceInsider obtained materials that vaccinemakers, governments, and WHO provided to the 100 or so participants at a meeting on 'access and financing' of Ebola vaccines. The documents put hard numbers on what until now have been somewhat fuzzy academic discussions. And they make clear to the attendees—who include representatives from governments, industry, philanthropies, and nongovernmental organizations—that although testing and production are moving forward at record speed, knotty issues remain.

Ubuntu 14.10 Released With Ambitious Name, But Small Changes

Slashdot - Thu, 10/23/2014 - 21:46
Ubuntu 14.10, dubbed Utopic Unicorn, has been released today (here are screenshots). PC World says that at first glance "isn't the most exciting update," with not so much as a new default wallpaper — but happily so: it's a stable update in a stable series, and most users will have no pressing need to update to the newest version. In the Ubuntu Next unstable series, though, there are big changes afoot: Along with Mir comes the next version of Ubuntu’s Unity desktop, Unity 8. Mir and the latest version of Unity are already used on Ubuntu Phone, so this is key for Ubuntu's goal of convergent computing — Ubuntu Phone and Ubuntu desktop will use the same display server and desktop shell. Ubuntu Phone is now stable and Ubuntu phones are arriving this year, so a lot of work has gone into this stuff recently. The road ahead looks bumpy however. Ubuntu needs to get graphics drivers supporting Mir properly. The task becomes more complicated when you consider that other Linux distributions — like Fedora — are switching to the Wayland display server instead of Mir. When Ubuntu Desktop Next becomes the standard desktop environment, the changes will be massive indeed. But for today, Utopic Unicorn is all about subtle improvements and slow, steady iteration.

German Publishers Capitulate, Let Google Post News Snippets

Slashdot - Thu, 10/23/2014 - 20:59
itwbennett writes German publishers said they are bowing to Google's market power, and will allow the search engine to show news snippets in search results free of charge — at least for the time being. The decision is a step in an ongoing legal dispute between the publishers and Google in which, predictably, publishers are trying to get compensation from the search engine for republishing parts of their content and Google isn't interested in sharing revenue. The move follows a Google decision earlier this month — and which was to go into effect today — to stop using news snippets and thumbnails for some well-known German news sites.

We Need Distributed Social Networks More Than Ello

Critics said that the idealistic model would buckle under pressure from venture capitalists. But both gave scant mention to the fact that a distributed social networking protocol, backed by a player large enough to get people using it, would achieve all of the goals that Ello aspired to achieve, and more.

Ask Slashdot: Smarter Disk Space Monitoring In the Age of Cheap Storage?

Slashdot - Thu, 10/23/2014 - 19:17
relliker writes In the olden days, when monitoring a file system of a few 100 MB, we would be alerted when it topped 90% or more, with 95% a lot of times considered quite critical. Today, however, with a lot of file systems in the Terabyte range, a 90-95% full file system can still have a considerable amount of free space but we still mostly get bugged by the same alerts as in the days of yore when there really isn't a cause for immediate concern. Apart from increasing thresholds and/or starting to monitor actual free space left instead of a percentage, should it be time for monitoring systems to become a bit more intelligent by taking space usage trends and heuristics into account too and only warn about critical usage when projected thresholds are exceeded? I'd like my system to warn me with something like, 'Hey!, you'll be running out of space in a couple of months if you go on like this!' Or is this already the norm and I'm still living in a digital cave? What do you use, on what operating system?

Austin Airport Tracks Cell Phones To Measure Security Line Wait

Slashdot - Thu, 10/23/2014 - 18:21
jfruh writes If you get into the TSA security line at Austin-Bergstrom International Airport, you'll see monitors telling you how long your wait will be — and if you have a phone with Wi-Fi enabled, you're helping the airport come up with that number. A system implemented by Cisco tracks the MAC addresses of phones searching for Wi-Fi networks and sees how long it takes those phones to traverse the line, giving a sense of how quickly things are moving. While this is useful information to have, the privacy implications are a bit unsettling.
