Reading always seemed to be the most private of acts: just you and your imagination immersed in another world. But now, if you happen to be curled up with an e-reader, you're not alone.

Data is being collected about your reading habits. That information belongs to the companies that sell e-readers, like Amazon or Barnes & Noble. And they can share — or sell — that information if they like. One official at Barnes & Noble has said sharing that data with publishers might "help authors create even better books."

Herding cattle up the side of a mountain might seem like a lot of extra work, but for thousands of years, people have hauled their cows into the Alps to graze during the summer months. Why? It's all about great-tasting cheese.

Tell Me More's "Social Me" series looks at how young people interact online — with a focus on online identities, privacy issues and breakthroughs in Internet-based learning.

The Energy Department wants to make similar strides with an agency called ARPA-E. Over three years now in operation, ARPA-E has spent nearly $800 million on 285 experimental projects.

We invited the agency's deputy director, Cheryl Martin, into our studio so we can find out more about these projects. Good morning.

CHERYL MARTIN: Good morning.

Google wants you to know you're being watched. Or rather, the company wants you to know how and when the police get to watch what you do online.

For the first time, the company has posted its policies for when it gives up users' information to the government. It's part of a broader company strategy to push for tougher privacy laws.

The hacker-activist group Anonymous is claiming responsibility for taking down a government website Saturday. NPR's Giles Snyder reports for our Newscast unit:
