TechnoBabble Pro writes “The CAPTCHA idea sounds simple: prevent bots from massively abusing a website (e.g. to get many email or social network accounts, and send spam), by giving users a test which is easy for humans, but impossible for computers. Is there really such a thing as a well-balanced CAPTCHA, easy on human eyes, but tough on bots? TechnoBabble Pro has a piece on 3 CAPTCHA gotchas which show why any puzzle which isn’t a nuisance to legitimate users, won’t be much hindrance to abusers, either. It looks like we need a different approach to stop the bots.”

Hugh Pickens writes “Mass strandings of dolphins and whales could be caused because the animals are rendered temporarily deaf by military sonar, experiments have shown. Tests on a captive dolphin have demonstrated that hearing can be lost for up to 40 minutes on exposure to sonar and may explain several strandings of dolphins and whales in the past decade. Most strandings are still thought to be natural events, but the tests strengthen fears that exercises by naval vessels equipped with sonar are responsible for at least some of them. For example, in the Bahamas in March, 2000, 16 Cuvier’s beaked whales and Blainville’s beaked whales and a spotted dolphin beached during a US navy exercise in which sonar was used intensively for 16 hours (PDF). ‘The big question is what causes them to strand,’ says Dr. Aran Mooney, of the University of Hawaii. ‘What we are looking at are animals whose primary sense is hearing, like ours is seeing. Their ears are the most sensitive organ they have.’ In the experiment, scientists fitted a harmless suction cup to the dolphin’s head, with a sensor attached that monitored the animal’s brainwaves, and when the pings reached 203 decibels and were repeated, the neurological data showed the mammal had become deaf, for its brain no longer responded to sound. ‘We definitely showed that there are physiological and some behavioral effects [from repeated, loud sonar], but to extrapolate that into the wild, we don’t really know,’ said Mooney.”

mmmscience writes with this excerpt from the Examiner: “Big news in the medical world: scientists in Australia have found a way to stop the body from attacking organ transplants, greatly decreasing the possibility of organ rejection. … When a new tissue is introduced, one’s immune system kicks into overdrive, sending out cells known as killer T cells to attack and destroy the unknown tissue. … Professor Jonathan Sprent and Dr. Kylie Webster from Sydney’s Garvan Institute of Medical Research focused on a different type of T cells — known as regulatory T cells (Treg) — in this study. Tregs are capable of quieting the immune system, stopping the killer T cells from seeking out and attacking foreign objects.”

Digg’s release of a pervasive, software-free toolbar last week brought with it a sweet little surprise: the capability to jump to a random site or story that was recommended by other Digg users. For a site that’s run entirely by its community, this puts the power of browsing in the hands of an algorithm that does the deciding for you.

Hugh Pickens writes “Roger Friedman, an entertainment columnist for FoxNews.com, discovered over the weekend just what Rupert Murdoch means by ‘zero tolerance’ when it comes to movie piracy. On Friday, the film studio 20th Century Fox — owned by the News Corporation, the media conglomerate ruled by Mr. Murdoch — became angry after reading Friedman’s latest column, a review of ‘X-Men Origins: Wolverine,’ a big-budget movie that was leaked in unfinished form on the Web last week. Friedman posted a mini-review, adding, ‘It took really less than seconds to start playing it all right onto my computer.’ The film studio, which enlisted the FBI to hunt the pirate, put out a statement calling Friedman’s column ‘reprehensible’ while News Corporation weighed in with its own statement, saying it had asked Fox News to remove the column from its Web site. ‘When we advised Fox News of the facts,’ the statement said, ‘they promptly terminated Mr. Friedman.'”

BobB-nw writes “A new cloud storage vendor is entering the market, promising an enterprise-class file system with snapshots, replication, and other features designed to simplify adoption for existing users and applications. Zetta, founded in 2007 by veterans of Netscape, has million in funding and is coming out of stealth mode Monday with Enterprise Cloud Storage, a Web-based storage platform that will compete against Amazon’s Simple Storage Service and a growing number of cloud vendors. Zetta’s goal was to build a Web-based storage system that would be accepted by enterprise IT professionals for storing primary data. ‘Data growth rates are staggering. In businesses you see growth rates of 40 to 60 percent year over year,’ says CEO Jeff Treuhaft, a Zetta cofounder and formerly one of Netscape’s first employees. Another Zetta cofounder is Lou Montulli, an early Netscape employee who invented Web cookies.”

Andre writes “As their final-year project, an eight-man team of fourth-year electrical and computer-engineering students at the University of Waterloo in Ontario, Canada, constructed a robot-controlled, motor-and-actuator foosball table capable of playing against human opponents in a two-on-two fashion; one mechanical player controls two defensive rods (goalies and full-backs) and the other controls two offensive rods (half-backs and forwards). They considered the computers ‘medium-skilled’ players in that they were very competitive against beginners and fairly competitive against intermediates.”

Hugh Pickens writes “Chicks can add and subtract small numbers shortly after hatching, says Rosa Rugani at the University of Trento. Rugani reared chicks with five plastic containers of the kind found inside Kinder chocolate eggs. This meant the chicks bonded with the capsules, much as they do with their mother, making them want to be near the containers as they grew up. In one test, the researchers moved the containers back and forth behind two screens while the chicks watched. When the chicks were released into the enclosure, they headed for the screen obscuring the most containers, suggesting they had been able to keep track of the number of capsules behind each by adding and subtracting them as they moved. It is already known that many non-human primates and monkeys can count, and even domestic dogs have been found to be capable of simple additions but this is the first time the ability has been seen in such young animals, and with no prior training in problem solving of any kind.”

Time Warner Cable’s bandwidth caps are such a hit that the company is rolling them out in more cities this year. The caps start at 5GB per month, but Time Warner Cable’s CEO says that they are needed to cover its infrastructure costs. We’re (deeply) skeptical.

Akido37 writes “Time Warner Cable is expanding its transfer capping program to new markets in Rochester, NY, Austin, TX, San Antonio, TX, and Greensboro, NC. It seems they have been testing plans with 5, 10, 20, or 40GB of data transfer per month, with prices ranging from to a month. BusinessWeek quotes Time Warner Cable CEO Glenn Britt saying, ‘We need a viable model to be able to support the infrastructure of the broadband business … We made a mistake early on by not defining our business based on the consumption dimension.’ Ars Technica adds, ‘The BusinessWeek article notes that only 14 percent of users in TWC’s trial city of Beaumont, Texas even exceeded their caps at all. My own recent conversations with other major ISPs suggest that the average broadband user only pulls down 2-6GB of data per month as it is. One the one hand, this suggests that caps don’t really bother most people; on the other, it indicates that low cap levels aren’t needed to keep traffic ‘reasonable’ since it’s actually quite low to begin with.'”
