Female Sharks Can Reproduce Alone 293

mikesd81 writes "The Washington Post has an article about a team of American and Irish researchers that have discovered that some female sharks can reproduce without having sex, the first time that scientists have found the unusual capacity in such an ancient vertebrate species. Their report concludes that sharks can reproduce asexually through the process known as parthenogenesis (the growth and development of an embryo or seed without fertilization by a male). Scientists started investigating after a female hammerhead shark was mysteriously born at Omaha's Henry Doorly Zoo in a tank that housed 3 female sharks. It was originally thought one had stored sperm from a male shark before fertilizing an egg. However, baby shark's genetic makeup perfectly matched one of the females in the tank, with no sign of a male parent."

Feed Cannibalism Of The Young Allows Individual Fish To Specialize (sciencedaily.com)

Whitefish, Arctic char, threespine stickleback and some sunfishes display quite discrete groups living in the same lakes but utilizing different food resources in order to survive. The phenomenon is called "resource polymorphism." Why don't all species show this pattern? Early cannibalism is found in all species displaying resource polymorphism.

Golygydd Max writes: "Who says that Microsoft and open source developers are enemies? It's not Ubuntu founder Mark Shuttleworth. He says that Microsoft is not the patent threat Linux and open source developers should be worried about, and that the software giant will itself be fighting against the software patents system within a few years."

IT Departments Fear Growing Expertise of Users 499

flatfilsoc recommends a long article in CIO magazine on users who know too much and the IT leaders who fear them. Dubbing the universe of consumer technology the "shadow IT department," the article highlights the extent to which the boundary between users' workplace and home have broken down. It notes the increasing clash — familiar to anyone who works in a company with an IT department — between users' home-grown productivity boosters and IT's mandate to protect corporate data. The inherent tendency of the IT department to want to crack down and control technology that it doesn't supply should be resisted at all costs, according to CIO. The article outlines strategies for co-existence. It just might persuade some desperate CIO somewhere not to embark on a career-limiting path of decreeing against gmail and IM.

Submission + - More Privacy Tech - digital credentials & ecas

John Q Random writes: From the cypherpunks-write-code / privacy-through-advanced-crypto department, Stefan Brands company credentica.com announced their U-Prove library and SDK implementing ID tokens (also known as digital credentials or private credentials).

(Private Credentials are a cool PKI replacement and anonymous ecash tech that allows you to prove certified attributes like age, credit rating, group membership, etc without revealing who you are; to allow you to have a digital life without the digital dossier effect inherent in central databases like google's).

Following that Adam Back announcedcredlib, an open source implementation of Brands credentials (and the older more basic Chaum certificates).

Relates to recent news from IBM's Zurich labs on their identity-mixer project (reported on slashdot here) that is based on the less efficient Jan Camenisch and Anna Lysyanskaya credentials.

Why Microsoft Is Beating Apple At Its Own Game 418

ttom writes "OSWeekly.com looks at Microsoft's promotional strategy and concludes that Microsoft is beating Apple at its own game." From the article: "Apple is to blame for this, at least to some extent. They just had to go and release Boot Camp, didn't they? By the way, please don't take my sarcastic tone as an expression of my dissatisfaction for the product. I think it's great, and I really never expected to see something like Boot Camp come out of the Apple Camp. I know that users have bombarded them with requests for officially allowing Windows usage on a Mac, and the fact that they yielded to these requests is interesting because they've emphasized the OS X and Windows experiences as being completely separate for quite some time."
