So we know that Facebook gathers our personal information. It knows our friends, our significant others, the music we like, where we work. It’s enough to raise a lot of privacy concerns for a lot of people. But the social media site is trying to calm some of those worries. Facebook has just announced it’ll roll out a feature that will let users check out more of the information it has gathered. Still, that’s still only a fraction of the information Facebook has.

Energy and where to find it for an increasingly energy-hungry world is going to be an issue in the future, and so will be the management of the energy we have. A lot of smart people in America are going to need to address the ongoing issue of energy in a really smart way. That means getting serious about building a smart grid, a power grid that is constantly gathering and processing information. Maggie Koerth-Baker, the author of a new book on energy, says if we don’t smarten up our grid, we’ll see more blackouts, more headaches. Plus, Shakespeare broken down and 3D chocolate printing.

Happy National Robotics Week! Today is Robot Block Party day, and it’s just part of a weeklong series of events in all 50 states put on by major universities and private businesses. The goal? Pretty much to show off how neat robots are. But it also for recruiting the next generation of roboticists. Also, a new app says it can guide you to the dreams you want to have.

Tens of millions of iPads have been sold since the product first went on sale two years ago. It’s hard to peg an exact number since a bunch more have been sold in the time it’s taken you to read this sentence. They’re flying off the shelves, if they ever manage to get to the shelves. But despite the device’s cultural ubiquity, few Americans have been inside a Foxconn facility to see how it’s actually constructed. Rob Schmitz, China correspondent for Marketplace, is one of them. Rob was the second journalist to be allowed inside an Appe production line at the facility. We spoke to him about what he saw and heard.

For a lot of us who first got online in the 1990s, Yahoo! was a pretty special place. But that was a while ago and Yahoo! hasn’t really managed to roll with the punches all that well. It kind of got punched by the punches instead. What could be next for the tech company? Plus, social network fans shop differently.

The Flashback Trojan has infected over 600,000 Mac computers around the world, most of them in the United States, and it shows no signs of slowing down. It is unusual for bad guys to target Mac computers and while the incidents of big Mac attacks are still very slim compared to those on PCs, it’s happening more and more. We look into how it happened, and what to do next. Also, a new game lets you be the road instead of a car on the road.

The Windows Phone platform is about to get a big boost from Nokia. The Finnish company, which made it big in handset phones is launching the Lumia 900, a smartphone that runs on Windows and will be available (at least for a while) at $99, making it half the price of the average new smartphone. But does the device have what it takes to compete against the big two and give customers a legitimate third major option? Also, we debate pros and cons of Google Glasses.

A new report from the American Civil Liberties Union says that law enforcement agencies are frequently using cell phone tracking information provided by wireless carriers. The ACLU claims the information is readily available, and that police are interested in figuring out where people go and what they do. But what is that info being used for? Finally, scientists at MIT have developed these tiny magnetic blocks that can communicate with one another and come together to replicate objects.

Up to 1.5 million credit card numbers for Visa and MasterCard accounts have been stolen from the databases of a company called Global Payments. We hear about how to know and what to do if you’re affected. Also on the show, evolving robots that are designed to be like animals — and even reproduce like animals.
