UK Team Claims Breakthrough In Universal Cancer Test 33

Posted by Unknown Lamer
from the coming-to-a-patent-office-near-you dept.
An anonymous reader writes UK researchers say they've devised a simple blood test that can be used to diagnose whether people have cancer or not. The Lymphocyte Genome Sensitivity (LGS) test looks at white blood cells and measures the damage caused to their DNA when subjected to different intensities of ultraviolet light (UVA), which is known to damage DNA. The results of the empirical study show a distinction between the damage to the white blood cells from patients with cancer, with pre-cancerous conditions and from healthy patients. "Whilst the numbers of people we tested are, in epidemiological terms, quite small (208), in molecular epidemiological terms, the results are powerful," said the team's lead researcher. "We've identified significant differences between the healthy volunteers, suspected cancer patients and confirmed cancer patients of mixed ages at a statistically significant level .... This means that the possibility of these results happening by chance is 1 in 1000." The research is published online in the FASEB Journal, the U.S. Journal of the Federation of American Societies for Experimental Biology.

Ask Slashdot: Where Can I Find Resources On Programming For Palm OS 5? 95

Posted by Unknown Lamer
from the civilized-pda-for-a-civilized-business-climate dept.
First time accepted submitter baka_toroi (1194359) writes I got a Tungsten E2 from a friend and I wanted to give it some life by programming for it a little bit. The main problem I'm bumping up against is that HP thought it would be awesome to just shut down every single thing related to Palm OS development. After Googling a lot I found out CodeWarrior was the de facto IDE for Palm OS development... but I was soon disappointed as I learned that Palm moved from the 68K architecture to ARM, and of course, CodeWarrior was just focused on Palm OS 4 development.

Now, I realize Palm OS 4 software can be run on Palm OS 5, but I'm looking to use some of the 'newer' APIs. Also, I have the Wi-fi add-on card so I wanted to create something that uses it. I thought what I needed was PODS (Palm OS Development Suite) but not only I can't find it anywhere but also it seems it was deprecated during Palm OS's lifetime. It really doesn't help the fact that I'm a beginner, but I really want to give this platform some life. Any general tip, book, working link or even anecdotes related to all this will be greatly appreciated.

Smoking Mothers May Alter the DNA of Their Children 86

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 102

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 52

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?

New Findings On Graphene As a Conductor With IC Components 31

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 174

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 94

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) 29

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.

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?

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 134

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 29

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 89

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 24

Posted by timothy
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."
