*Do Not Track Approach Balances User Preferences with Personalized Web Experiences*

CAMBRIDGE, Mass. – 17 Nov 2011: To address rising concerns about privacy on the Web, W3C has published two first drafts for standards that allow users to express preferences about online tracking:

Tracking Preference Expression (DNT), which defines mechanisms for users to express cross-site tracking preferences and for sites to indicate whether they honor these preferences.
Tracking Compliance and Scope, which defines the meaning of a “Do Not Track” preference and sets out practices for websites to comply with this preference.

These documents are the early work of a broad set of stakeholders in the W3C Tracking Protection Working Group, including browser vendors, content providers, advertisers, search engines, and experts in policy, privacy, and consumer protection. W3C invites review of these early drafts, which are starting points of work to come. W3C expects them to become standards by mid-2012. (more…)

The birth of the Gamburtsev Subglacial Mountains buried beneath the vast East Antarctic Ice Sheet – a puzzle mystifying scientists since their first discovery in 1958 – is finally solved. The remarkably long geological history explains the formation of the mountain range in the least explored frontier on Earth and where the Antarctic Ice Sheet first formed. The findings are published this week in the journal Nature. (more…)

ANN ARBOR, Mich.— Angels are everywhere today—on lapel pins, magnetic dashboard figures, keepsake ornaments and in a Pulitzer Prize-winning play. But interest in angels is more than a contemporary fad. According to a University of Michigan historian, angels stirred intense interest in the early years of Christianity as well.

“Just as many people today think of pets as part of their families, many people in the first 500 years of Christianity were convinced that angels were part of their lives,” said Ellen Muehlberger, assistant professor of Near Eastern studies and history at the U-M College of Literature, Science, and the Arts.

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.

In contrast, mature cells in children and adults depend more on cell mitochondria to convert sugar and oxygen into carbon dioxide and water during a high energy–producing process called oxidative phosphorylation. (more…)
