Having tabs in Mozilla’s Thunderbird 3 email client is a nice feature, but for the most part I hardly ever use them. I’ve find that they are bulky and take up a lot of space. Here’s a quick way to disable them.

The nanorobotic arm is built out of DNA origami: large strands of DNA gently encouraged to fold in precise ways by interaction with a few hundred short DNA strands. The products, around 100 nanometers in diameter, are eight times larger and three times more complex than what could be built with a simple crystalline DNA array, vastly expanding the space of possible structures. Other nanoscale structures or machines built by Dr. Seeman and his collaborators including a nanoscale walking biped, truncated DNA octahedrons, and sequence-dependent molecular switch arrays. Dr. Seeman has exploited structural features of DNA thought to be used in genetic recombination to operate his nanoscale devices, tapping into the very processes underlying all life.

Brain wave applications in the laboratory –- whether using EEG or the more invasive ECoG –- now include the ability to “mind read” vowels, consonants, and individual letters; algorithms to turn brain waves into musical scores; and even twittering by thought alone. Who needs a keyboard when you can simply think about what you want to say (or play musically) and have it recorded and/or communicated?
