Researchers from Rice University have found a type of amoeba that practices a sort of "primitive farming behavior." When their bacteria food become scarce, the Dictyostelium discoideum will group together and form a "fruiting body" that will disperse bacteria spores to a new area. From the article: "The behavior falls short of the kind of 'farming' that more advanced animals do; ants, for example, nurture a single fungus species that no longer exists in the wild. But the idea that an amoeba that spends much of its life as a single-celled organism could hold short of consuming a food supply before decamping is an astonishing one. More than just a snack for the journey of dispersal, the idea is that the bacteria that travel with the spores can 'seed' a new bacterial colony, and thus a food source in case the new locale should be lacking in bacteria." It's good to know that even a single celled creature is not immune to the pull of Farmville.

An article at Gamasutra takes an in-depth look at how Zynga's new browser-based social game CityVille managed to accumulate tens of millions of players in the relatively short time since its launch early this month. Quoting: "The Facebook interface induces a high degree of user blindness. It does not do a great job of exposing new games and applications, and lacks a directory or a 'Featured in the App Store' style of editorial (as Apple does for the iPhone), which means that for most developers there are huge problems in getting their games in front of users' eyeballs. With all of the free advertising channels on the platform now constrained or dead, this has meant that the Facebook economy has been acquiring an increasingly Darwinian shape. Where it used to be an egalitarian environment in which any developer could strike it big, over the last year it has become top-heavy with larger developers accruing exponential success, and cutting off oxygen to smaller companies by default."

FlorianMueller writes "The US International Trade Commission, which is increasingly popular as a patent enforcement agency, voted to investigate a complaint filed by Motorola against Microsoft last month. Motorola claims that the Xbox infringes five of its patents. In October, Microsoft complained against Motorola, alleging patent infringement by its Android-based smartphones. Apple, Nokia and HTC are also involved with ITC investigations as complainants and respondents. A new one-page overview document shows the ongoing ITC investigations related to smartphones and the products that the complainants would like to have banned from entry into the US market. The good news is that any import bans won't be ordered until long after Christmas. The ITC is faster than courts, but not that fast."

It turns out the key to a male crocodile's heart is a sonic boom. Crocodiles at an Israeli farm have begun making mating calls in response to sonic booms created by air force planes breaking the sound barrier. From the article: "The males have already begun their mating calls, described by the newspaper as 'the sound a vehicle breaking,' normally reserved for the crocodiles' spring mating season, Israeli newspaper Maariv reported. David Golan of the Hamat Gadar crocodile farm in the Golan Heights, believes the reptiles were responding to the sonic booms, wrongly believing they were the calls of rival males encroaching on their territory

An anonymous reader writes "A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground. The magnetic field strength is 25 Gauss, or 50 times stronger than the magnetic field at the surface that makes compass needles align north-south. Though this number is in the middle of the range geophysicists predict, it puts constraints on the identity of the heat sources in the core that keep the internal dynamo running to maintain this magnetic field."

Bethesda took advantage of the Video Game Awards this weekend to announce the fifth installment of the Elder Scrolls series, titled Skyrim. The game is planned for November 2011, and a teaser trailer has been posted on the Elder Scrolls website. Details are sparse, though the game will apparently run on an "all-new" engine.

mernilio writes "According to UPI: 'A Massachusetts school district superintendent said a memo banning sixth graders from carrying pencils was written without district approval. North Brookfield School District interim Superintendent Gordon Noseworthy said Wendy Scott, one of two sixth-grade teachers at North Brookfield Elementary School, did not get approval from administrators before sending the memo to all sixth-grade parents, the Worcester Telegram & Gazette reported Thursday. The memo said students would no longer be allowed to bring writing implements to school. It said pencils would be provided for students in class and any students caught with pencils or pens after Nov. 15 would face disciplinary action for having materials 'to build weapons.'"
