Could Assortative Mating Explain Autism? 286

Posted by samzenpus on Wednesday August 24, 2011 @04:11PM from the and-nerd-begot-nerd dept.

clm1970 writes "Researcher Simon Baron-Cohen has put forth the theory that 'how we mate and marry' could explain the increase in rates of Autism Spectrum Disorders, particularly Asperger's. When two technically minded people marry and have children, so the provocative theory goes, they are more apt to produce a child who crosses the line into mild autism."

No resources are freed for any future generations of database contaminants to breed on by filtering. And, the notion of evolution would also require changes to the contaminants, which don't really happen. So by all means, filter. It will leave harder-to-detect contaminants there, but they won't become more numerous.

Turn the picture around and re-scan, that way you effectively have the light coming from different angles by each scan. No need to modify the scanner.

Panel Recommends Space Science, Not Stunts 304

Posted by Soulskill on Sunday August 02, 2009 @09:27AM from the lunar-mission-accomplished-banner dept.

wisebabo writes "A panel reporting to President Obama is recommending that we skip landing on the Moon and Mars and instead consider progressively deeper space voyages (first to the L1 Earth-Moon point, then perhaps the L2 Earth-Sun point, then a Mars flyby/orbit or asteroid visits). While in Mars orbit, the astronauts could send robotic probes to land on the surface, which could be much more effective than current rovers without the 10-minute time lag to Earth. I, for one, whole-heartedly agree that this approach would lead to 'the most steady cadence of steady improvement,' and keep us from inconsistent achievements in space (like not leaving Earth orbit for 40 years). Some would say that this approach would be lacking in the photo-ops necessary to maintain interest in the space program (no footprints on Martian soil) but I think there would be plenty of cool vistas — perhaps a rendezvous with a comet, or even orbiting one of the moons of Jupiter, assuming they figure out radiation shielding — to keep the taxpayer dollars flowing. The science return would be much greater because it would hopefully utilize both man and machine at their best; robots on one-way trips down into a gravity well while the humans provide the intuition and flexibility from orbit."

Netflix calculates the score shown on the leaderboard from a set of rating predictions submitted by a team. The team does not, and will not, know the correct answers. For testing their algorithms, the teams use another dataset. The two datasets, part of the package made available to the competitors, are known as "qualifying" and "probe".

Bing Users' Click-Through Rate 55% Higher Than Google Users' 268

Posted by timothy on Sunday July 26, 2009 @02:30PM from the hey-now-I-like-that-ads-subsidize-stuff dept.

An anonymous reader writes "Techcrunch is running a story that shows some pretty significant differences in the clicking habits of users of Yahoo, Google, and Bing. As it turns out, folks who arrive at websites via Bing are 55% more likely to click on an ad than if they arrived from Google (data based on the Chitika network). Essentially, people who use Bing are far more susceptible to advertising. Bing has acquired a decent market share in such a short time, but could it just be that they've reaped the low hanging fruit of those particularly persuaded by advertising? When their huge marketing campaign winds down, what kind of staying power will it have?"

World's First 3D Webcam Tested 124

CNETNate writes "The world's first 3D webcam not only takes anaglyphic images, but will let you have a stereoscopic 3D video chat over the Internet. It's the work of a unique camera called 'Minoru,' which has been tested and documented in a feature today. Be warned though: anaglyphic photography was clearly not invented to create comfortably-viewable videos."

Choosing Better-Quality JPEG Images With Software? 291

Posted by timothy on Thursday July 16, 2009 @06:02PM from the on-the-tip-of-my-script dept.

kpoole55 writes "I've been googling for an answer to a question and I'm not making much progress. The problem is image collections, and finding the better of near-duplicate images. There are many programs, free and costly, CLI or GUI oriented, for finding visually similar images — but I'm looking for a next step in the process. It's known that saving the same source image in JPEG format at different quality levels produces different images, the one at the lower quality having more JPEG artifacts. I've been trying to find a method to compare two visually similar JPEG images and select the one with the fewest JPEG artifacts (or the one with the most JPEG artifacts, either will serve.) I also suspect that this is going to be one of those 'Well, of course, how else would you do it? It's so simple.' moments."

China Bans Gold Farming 293

Posted by ScuttleMonkey on Monday June 29, 2009 @03:10PM from the shooting-yourself-in-the-foot dept.

InformationWeek is reporting that the Chinese government has declared a ban on the sale of virtual goods for real currency. This move is poised to shut down a several billion yuan a year business that has been growing by leaps and bounds every year. "The trading of virtual currency for real cash employs hundreds of thousands of people worldwide and generates between $200 million and $1 billion annually, according to a 2008 survey conducted by Richard Heeks at the University of Manchester. He estimates that between 80% and 85% of gold farmers are based in China. [...] Game companies typically forbid gold farming but committed virtual currency traders find ways around such rules. Some game companies have recognized the futility of trying to ban the practice and have built virtual commerce into their game infrastructure."

Need a Favor? Talk To My Right Ear 288

Posted by samzenpus on Thursday June 25, 2009 @12:18AM from the bene-gesserit-tricks dept.

Hugh Pickens writes "The Telegraph reports that scientists have found that if you want to get someone to do something, ask them in their right ear. Known as the 'right ear advantage,' scientists believe it is because information received through the right ear is processed by the left hand side of the brain which is more logical and better at deciphering verbal information than the right side of the brain. 'Talk into the right ear you send your words into a slightly more amenable part of the brain,' say researchers. The team, led by Dr. Luca Tommasi and Daniele Marzoli from the University of Chieti in central Italy, observed the behavior of hundreds of people in three nightclubs across the city where they intentionally addressed 176 people in either their right or their left ear when asking for a cigarette. They obtained significantly more cigarettes when they made their request in a person's right ear compared with their left. 'These results seem to be consistent with the hypothesized specialization of right and left hemispheres,' say researchers. 'We can also see this tendency when people use the phone, most will naturally hold it to their right ear.'"

Where Does a Geek Find a Social Life? 1354

JustShootMe writes "I have a question for my fellow Slashdotters, and yes, I realize I am entering the lion's den covered in tasty meat-flavored sauce. I have never been a very social person, preferring to throw myself into technology; therefore, I've been spectacularly unsuccessful in developing any meaningful interpersonal relationships. Lately I have begun to feel that this situation is not tenable, and I would like to fix it. But I really don't know how and haven't the faintest idea where to start. I know that I am in the minority and that there are many different kinds of Slashdot readers, most of whom have more experience in this realm than I do. So please tell me: how, and more importantly, where do you meet fellow geeks — preferably including some of the opposite gender — in meatspace?"

English Market Produces Energy With Kinetic Plates 404

Posted by samzenpus on Thursday June 18, 2009 @02:51AM from the parking-power dept.

Johnathan Martinez writes "Sainsbury's market in England has installed 'kinetic energy' plates in the parking lot of its store in Gloucester. The plates are an experiment with a newer energy producing technology. The plates create as much as 30 kWh of energy as cars drive over them. The weight of the cars puts pressure on the plates creating kinetic energy to run a generator. The current is used to power the store and will lower the energy consumption of the market."

Texas Makes Zombie Fire Ants 398

Posted by samzenpus on Wednesday May 13, 2009 @10:20PM from the what-could-go-wrong dept.

eldavojohn writes "What do you do when a foreign species has been introduced to your land from another continent? Bring over the natural predator from the other continent. Scientists in Texas have introduced four kinds of phorid flies from South America to fight fire ants. These USDA approved flies dive bomb ants and lay an egg inside the ant. The maggot hatches and eats away juicy tender delicious ant brain until the ant is nothing more than a zombie that wanders around for two weeks before the head falls off and the ant dies. A couple of these flies will cause the ants to modify their behavior and this will be a very slow acting solution to curb the $1 billion in damage these ants do to Texas cattle ranches and — oddly enough — electrical equipment like circuit breakers. You may remember zombifying parasites hitting insects like cockroaches."

All Solid State Drives Suffer Performance Drop-off 150

Posted by CmdrTaco on Friday May 08, 2009 @05:48PM from the storage-slows-down-as-you-approach-5pm dept.

Lucas123 writes "The recent revelation that Intel's consumer X25-M solid state drive had a firmware bug that drastically affected its performance led Computerworld to question whether all SSDs can suffer performance degradation due to fragmentation issues. It seems vendors are well aware that the specifications they list on drive packaging represent burst speeds when only sequential writes are being recorded, but after use performance drops markedly over time. The drives with better controllers tend to level out, but others appear to be able to suffer performance problems. Still not fully baked are benchmarking standards that are expected out later this year from several industry organizations that will eventually compel manufacturers to list actual performance with regard to sequential and random reads and writes as well as the drive's expected lifespan under typical conditions."

New Flu Strain Appears In the US and Mexico 315

Posted by Soulskill on Saturday April 25, 2009 @01:20PM from the fluent-in-english-and-spanish dept.

Combat Wombat writes with this excerpt from Reuters: "A strain of flu never seen before has killed up to 60 people in Mexico and also appeared in the United States, where eight people were infected but recovered, health officials said on Friday. Mexico's government said at least 20 people have died of the flu and it may also be responsible for 40 other deaths. [The government] shut down schools and canceled major public events in Mexico City to try to prevent more deaths in the sprawling, overcrowded capital. ... Close analysis showed the disease is a mixture of swine, human and avian viruses, according to the CDC. Humans can occasionally catch swine flu from pigs but rarely have they been known to pass it on to other people. Mexico reported 1,004 suspected cases of the new virus, including four possible cases in Mexicali on the border with California.
