Anna Sale here on the day shift.

We are continuing to watch the Gulf Coast today, monitoring when and if BP's next attempt to plug the well leak — a process called "top kill" which involves plugging the leak with fluids — will happen. Tomorrow, President Obama will hold a press conference to announce new oil development regulations and he'll travel to the Gulf Coast on Friday. We're reaching out to experts and economists today to get a sense of how this disaster affects the economics of energy development. We're asking what the balance sheets for energy development would look like if these worst case scenarios and non-market expenses were accounted for up-front. We're also asking you what you still need to know. It's been more than a month since oil started gushing out of a well in the Gulf Coast, and we've been covering it ever since. What questions do you still have about its long-term effects and the effort to contain the damage?

We're also monitoring Facebook's announcement of new privacy policies today. We've been asking you about your experiences (good and bad) with sharing personal information on social networks. Tomorrow, we'll look at the power of Facebook. Facebook CEO Mark Zuckerberg has compared his legions of users to the population of countries, and that was back when Facebook just had 175 million users, not the 500 million registered today. We'll look at the social media network's power, its reach, and how Zuckerberg measures up as a world leader.

In our weekly look at tech, we're going to home in on military technology that's gone civilian. We'll look at what common technologies got their start on the battlefield and get a sense of what's to come — from cyborg insects, telepathic helmets, and electricity-generating pants. I don't know about you, but I want to get my hands on one of those helmets for my next poker game.
