If I were Neil deGrasse Tyson—host of the Pluto Files and director of the Hayden Planetarium—I wouldn't be able to sleep at night. Not after reading the hate mail from thousands of outraged American kids.

The kids wrote to de Grasse Tyson demanding an explanation about why scientists changed Pluto's classification from planet into a Kuiper Belt object. The Natural History Museum also retired it from their Solar System model, which logically got a lot of kids reaching for their pellet guns.

We just finished watching Google's live announcement of the launch of the Google App Marketplace. Keep reading for information on what they're offering users and developers. Oh, and know that the Marketplace is live today. Updating.

The event is called "Google Campfire One" and it's all about how easy it will be to create, set up, and install apps using Google's App Marketplace. It appears that the big focus is on how everything—apps and existing Google products—will work together seamlessly and allow for all your tools and data to sit in the cloud. Right now the appeal is for business applications, but the potential seems incredible.

The first portion of the announcement is about what developers will give and get in this whole deal. Google is offering them access to 25 million users and only asking for a one-time fee of $100 and 20% revenue in exchange—that's less than what access to Apple's App Store requires. Of course, Google is providing a solid system with apps being authenticated using OpenID, secured using oAuth, and made available through a universal Google Apps navigation system.

While there are already 50 partners right at launch, we're hearing that after new apps are submitted, they may take a few days to show up in the Marketplace—mind you, there's no word on what kind of approval process there is. But once an app is in the Marketplace, it's easy for users or buyers to add them to their Google accounts: They agree to some terms of service, grant access to data—such as Gmail or GCal, and enable the app. Tada! It'll show up in the new apps drop down.

Now apparently development of these apps is so simple that there are 40 developers who are on a bus traveling to an SXSW event and working on apps right now.

It looks like apps will be easy to integrate into existing Google products as seen by a demo of a payroll app by Intuit—information from it was embedded into Gmail or Google Docs.

Now remember how there have been some nice previews of YouTube videos in Gmail lately? Prepare to see more of that from these new apps because Google is offering developers the chance to set apps to be triggered by certain emails, events, or specific types of content.

What does all this mean right now? For business users, there are plenty of apps already available—ones for payroll, data entry, management, and an office suite—and they'll be able to run everything right from the cloud. For us plain Janes and Joes though, the Marketplace is full of potential at this moment. Think social media, data management, communication—all the things you already get from Google, just better.

Yes, my head's already in the cloud. Hopefully everything else will follow and I'll be able to work and play there.

For every time you've brought a scooter to the airport and wished it fit into the overhead compartment, I give you the Nexus: a battery-powered scooter that folds into a luggage-sized case. The TSA will love this.

Nexus is a concept designed by Francisco Lupin, and if it were either for a) sale or b) not guaranteed to get me arrested, I'd own one already. Its two electric engines run on four 12V batteries, and can achieve speeds of up to 15 km/h. It'll last two hours on one charge, though if you make it two minutes before being tackled by bored security personnel you deserve some kind of special award. [Tuvie via Dvice]

Wow. The PS3 is getting HD purchases and rentals from all six major studios. A quick search turns up that Xbox is missing Fox and, duh, Sony.

It's nice that Sony isn't handicapping the Playstation 3 in order to protect its blu-ray business.

Sony's got deals with Fox, Disney, Paramount, Itself, Universal and Warner. I'm impressed. Now I just have to remember my login for PS network.

Sure, these days it seems like everyone has an iPhone, but in bizarro 2010 literally everyone has a watchphone. They're miniature. They're wireless. They have geometric buttons. And they're eating bizarro AT&T's bandwidth alive. Oh, 1995, you are so naive.

After a decade of mystery, astronomers have now shown that a pair of white dwarf stars spin around each other in just 5.4 minutes, making them the fastest-orbiting and tightest binary star system ever found, the researchers claim.

Professors have banned laptops from their classrooms at George Washington University, American University, the College of William and Mary and the University of Virginia, among many others.
