Moochman writes "New Scientist reports on a technology Microsoft is developing to identify users based on their browsing habits. Quote: 'The software could get its raw information from a number of sources, including a new type of 'cookie' program that records the pages visited. Alternatively, it could use your PC's own cache of web pages, or proxy servers could maintain records of sites visited. So far it can only guess gender and age with any accuracy,' but the aim is to be able to identify name, occupation and location as well. On a related note, The Inquirer reports on Microsoft's plans to widen the use of its identity-verification technology CardSpace, which is built into Windows Vista and available as an add-on to XP. It's being envisioned as an identity solution for the entire internet: says Kim Cameron, pioneer of the technology, 'We feel it has to solve all use cases.' (Aha, so the anonymous use cases, too, eh?) One might ask, with all of this user-ID information on hand, how long will it be until the Feds come knocking on Microsoft's door asking for help? They already have."

Dik Zak writes with word of a paper published in the journal Hormones and Behavior. A study found that women take greater care over their appearance when they are at peak levels of monthly fertility. The researchers took two photos of each of 30 women, one near ovulation and one at the other end of her cycle. They then showed the paired photos (with faces obscured) to a group of observers, who were asked to judge in which photo the women were trying to look more attractive. The observers chose the "high fertility" subject nearly 60% more of the time than would be expected by chance.
