Think the memory card in your camera is high-capacity? It's got nothing on DNA. With data accumulating at a faster rate now than any other point in human history, scientists and engineers are looking to genetic code as a form of next-generation digital information storage.

Wikipedia is a wonderful resource, the kind of website that makes you marvel at what the internet can achieve. But it's only as good as its contributors and, while some are extremely committed, the sad truth is that the project is running out of editors and new admins.

Visualizing how the world's ideas fit together is no mean feat. But now you don't have to struggle, because Brendan Griffen has mined Wikipedia to create a map of how the world's greatest thinkers influenced each other.

If you think your home Wi-Fi connection is fast, think again. Scientists have been working on a new way to transmit data wirelessly, and they can now transfer a scorching 2.5 terabits of information per second.

When people discuss data privacy, they think about Google's grasp on their email, Apple's lack of iPhone address book security, or some other scenario which immediately affects them. But the New York Times reports that there is one organization few of us ever consider:
