Smoking Mothers May Alter the DNA of Their Children 14

Posted by Unknown Lamer
from the that-explains-the-hooves dept.
sciencehabit (1205606) writes "Pregnant women who smoke don't just harm the health of their baby—they may actually impair their child's DNA, according to new research. A genetic analysis shows that the children of mothers who smoke harbor far more chemical modifications of their genome — known as epigenetic changes — than kids of non-smoking mothers. Many of these are on genes tied to addiction and fetal development. The finding may explain why the children of smokers continue to suffer health complications later in life.

OKCupid Experiments on Users Too 43

Posted by Unknown Lamer
from the statistics-are-only-skin-deep dept.
With recent news that Facebook altered users' feeds as part of a psychology experiment, OKCupid has jumped in and noted that they too have altered their algorithms and experimented with their users (some unintentional) and "if you use the Internet, you’re the subject of hundreds of experiments at any given time, on every site. That’s how websites work.". Findings include that removing pictures from profiles resulted in deeper conversations, but as soon as the pictures returned appearance took over; personality ratings are highly correlated with appearance ratings (profiles with attractive pictures and no other information still scored as having a great personality); and that suggesting a bad match is a good match causes people to converse nearly as much as ideal matches would.

Samsung Delays Tizen Phone Launch 33

Posted by Unknown Lamer
from the enlightenment-deemed-too-cool-for-you dept.
New submitter tekxtc (136198) writes Slashdot has reported in the past that a Tizen phone is coming and that the design and photos leaked. But, it has just been announced that the launch of the first Tizen phone has been delayed because of its Tizen's small ecosystem. Should it ever ship? Haven't Android and iOS completely cornered the market? Is there any hope for the likes of Tizen, Firefox OS, and Windows on phones and tablets?

from the honey-I-shrunk-the-cpu dept.
ClockEndGooner (1323377) writes Philadelphia's NPR affiliate, WHYY FM, reported today on their Newsworks program that a research team at the University of Pennsylvania have released their preliminary findings on the use of graphene as a conductor in the next generation of computer chips. From the article: "'It's very, very strong mechanically, and it is an excellent electronic material that might be used in future computer chips,' said Charlie Johnson, a professor of physics and astronomy at the University of Pennsylvania. ... Future graphene transistors, Johnson said, are likely to be only tens of atoms across."

The Misleading Fliers Comcast Used To Kill Off a Local Internet Competitor 116

Posted by Unknown Lamer
from the muni-broadband-madness! dept.
Jason Koebler (3528235) writes In the months and weeks leading up to a referendum vote that would have established a locally owned fiber network in three small Illinois cities, Comcast and SBC (now AT&T) bombarded residents and city council members with disinformation, exaggerations, and outright lies to ensure the measure failed. The series of two-sided postcards painted municipal broadband as a foolhardy endeavor unfit for adults, responsible people, and perhaps as not something a smart woman would do. Municipal fiber was a gamble, a high-wire act, a game, something as "SCARY" as a ghost. Why build a municipal fiber network, one asked, when "internet service [is] already offered by two respectable private businesses?" In the corner, in tiny print, each postcard said "paid for by SBC" or "paid for by Comcast." The postcards are pretty absurd and worth a look.

A Fictional Compression Metric Moves Into the Real World 73

Posted by Unknown Lamer
from the best-thing-since-sliced-scatterplots dept.
Tekla Perry (3034735) writes The 'Weissman Score' — created for HBO's "Silicon Valley" to add dramatic flair to the show's race to build the best compression algorithm — creates a single score by considering both the compression ratio and the compression speed. While it was created for a TV show, it does really work, and it's quickly migrating into academia. Computer science and engineering students will begin to encounter the Weissman Score in the classroom this fall."

A Credit Card-Sized, Arduino-Based Game Device (Video) 25

Posted by Roblimo
from the not-quite-nanotech-but-moving-in-that-direction dept.
Slashdot's Tim Lord was cruising the halls at OSCON, where he spotted Kevin Bates and his tiny Arduino-based device, called the Arduboy. On Kevin's Tindie.com sales page, he says the games it can run include, "Space Rocks, Snake, Flappy Ball, Chess, Breakout, and many more...The most exciting one could be made by you!" || His work with Arduboy got Kevin invited to the recent White House Maker Faire, where he rubbed shoulders (and shot selfies with) Bill Nye the Science Guy, Will.i.am from the Black Eyed Peas, and Arduino creator Massimo Banzi. || Does Kevin have a Kickstarter in the works? There's nothing about Arduboy on Kickstarter.com, and given the Arduboy's simplicity and low price (currently $50), plus stories about it everywhere from Time.com to engadget to Slashdot, he may not need any financing or capital to make his idea succeed.

Ask Slashdot: Preparing an Android Tablet For Resale? 76

from the link-free-cloth-and-a-.45 dept.
UrsaMajor987 (3604759) writes I have a Asus Transformer tablet that I dropped on the floor. There is no obvious sign of damage but It will no longer boot. Good excuse to get a newer model. I intend to sell it for parts (it comes with an undamaged keyboard) or maybe just toss it. I want to remove all my personal data. I removed the flash memory card but what about the other storage? I know how to wipe a hard drive, but how do you wipe a tablet? If you were feeling especially paranoid, but wanted to keep the hardware intact for the next user, what would you do?

Lots Of People Really Want Slideout-Keyboard Phones: Where Are They? 348

Posted by timothy
from the could-be-anywhere-really dept.
Bennett Haselton writes: I can't stand switching from a slideout-keyboard phone to a touchscreen phone, and my own informal online survey found a slight majority of people who prefer slideout keyboards even more than I do. Why will no carrier make them available, at any price, except occasionally as the crummiest low-end phones in the store? Bennett's been asking around, of store managers and users, and arrives at even more perplexing questions. Read on, below.

US States Edge Toward Cryptocoin Regulation 125

Posted by timothy
from the hey-these-still-smell-like-dollars dept.
SonicSpike points out an article from the Pew Charitable Trusts' Research & Analysis department on the legislation and regulation schemes emerging in at least a few states in reaction to the increasing use of digital currencies like Bitcoin. A working group called the Conference of State Bank Supervisors’ Emerging Payments Task Force has been surveying the current landscape of state rules and approaches to digital currencies, a topic on which state laws are typically silent. In April, the task force presented a model consumer guidance to help states provide consumers with information about digital currencies. A number of states, including California, Massachusetts and Texas, have issued warnings to consumers that virtual currencies are not subject to “traditional regulation or monetary policy,” including insurance, bonding and other security measures, and that values can fluctuate dramatically. ... The article focuses on the high-population, big-economy states of New York, California and Texas, with a touch of Kansas -- but other states are sure to follow. Whether you live in the U.S. or not, are there government regulations that you think would actually make sense for digital currencies?

Internet Census 2012 Data Examined: Authentic, But Chaotic and Unethical 26

Posted by timothy
from the could-have-been-worse dept.
An anonymous reader writes "A team of researchers at the TU Berlin and RWTH Aachen presented an analysis of the Internet Census 2012 data set (here's the PDF) in the July edition of the ACM Sigcomm Computer Communication Review journal. After its release on March 17, 2013 by an anonymous author, the Internet Census data created an immediate media buzz, mainly due to its unethical data collection methodology that exploited default passwords to form the Carna botnet. The now published analysis suggests that the released data set is authentic and not faked, but also reveals a rather chaotic picture. The Census suffers from a number of methodological flaws and also lacks meta-data information, which renders the data unusable for many further analyses. As a result, the researchers have not been able to verify several claims that the anonymous author(s) made in the published Internet Census report. The researchers also point to similar but legal efforts measuring the Internet and remark that the illegally measured Internet Census 2012 is not only unethical but might have been overrated by the press."

Oracle Offers Custom Intel Chips and Unanticipated Costs 81

Posted by timothy
from the your-fries-come-with-lobster dept.
jfruh (300774) writes "For some time, Intel has been offering custom-tweaked chips to big customers. While most of the companies that have taken them up on this offer, like Facebook and eBay, put the chips into servers meant for internal use, Oracle will now be selling systems running on custom Xeons directly to end users. Those customers need to be careful about how they configure those systems, though: in the new Oracle 12c, the in-memory database option, which costs $23,000 per processor, is turned on by default."

Attackers Install DDoS Bots On Amazon Cloud 23

from the fully-buzzword-compliant dept.
itwbennett (1594911) writes "Attackers are exploiting a vulnerability in distributed search engine software Elasticsearch to install DDoS malware on Amazon and possibly other cloud servers. Last week security researchers from Kaspersky Lab found new variants of Mayday, a Trojan program for Linux that's used to launch distributed denial-of-service (DDoS) attacks. The malware supports several DDoS techniques, including DNS amplification. One of the new Mayday variants was found running on compromised Amazon EC2 server instances, but this is not the only platform being misused, said Kaspersky Lab researcher Kurt Baumgartner Friday in a blog post."

Google's Mapping Contest Draws Ire From Indian Government 86

from the you-can't-look-there dept.
hypnosec writes with news that India's Central Bureau of Investigation has ordered a preliminary enquiry (PE) against Google for violating Indian laws by mapping sensitive areas and defence installations in the country. As per the PE, registered on the basis of a complaint made by the Surveyor General of India's office to the Union Home Ministry, Google has been accused of organizing a mapping competition dubbed 'Mapathon' in February-March 2013 without taking prior permission from Survey of India, country's official mapping agency. The mapping competition required citizens to map their neighbourhoods, especially details related to hospitals and restaurants. The Survey of India (SoI), alarmed by the event, asked the company to share its event details. While going through the details the watchdog found that there were several coordinates having details of sensitive defence installations which are out of the public domain."

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film 109

Posted by timothy
from the high-voltage dept.
puddingebola (2036796) writes "A team at Stanford has created a stable Lithium anode battery using a carbon honeycomb film. The film is described as a nanosphere layer that allows for the expansion of Lithium during use, and is suitable as a barrier between anode and cathode. Use of a lithium anode improves the coulombic efficiency and could result in longer range batteries for cars." The linked article suggests that the 200-mile-range, $25,000 electric car is a more realistic concept with batteries made with this technology, though some people are more interested in super-capacity phone batteries.
