I'm not sure we want to develop cheaper ways for creating gasoline, considering the environmental cost, but at least the option is available.

Nanotechnology Update

Researchers have found a new way to make transistors smaller and faster using self-assembled, self-aligned, and defect-free nanowire channels made of gallium arsenide:

Nanotechnology Update

(Could also be Computer Update)

"Unzipped" carbon nanotubes create "nanoribbons" which could lead to much faster computers:

It seems like they're coming up with more and more configurations for carbon at the nanoscale: buckyballs, nanotubes, nanosheets and now nanoribbons.

Robotics Update

Researchers develop first flying micro-robot:

Alternative Energies Update

Carbon nanotubes are used to create direct and efficient solar propulsion for water vehicles:

"When light is focused onto it, a boat about a centimeter long can travel as fast as eight centimeters per second. The second machine is a simple rotor with one nanotube strip on one side of each of its four fins. When exposed to direct sunlight, it spins at about 70 rotations per minute."

Alternative Energies Update

Incorporating diatoms into thin film solar cells makes them three times as energy efficient:

This is an early ancestor of the holy grail of nanotechnology: a desktop factory, which will allow us to manufacture anything we want in our own homes. No need to buy products anymore!

Robotics Update

"In recent decades, robots have replaced millions of manual laborers; now they're moving in on scientists, too. A fully automated robotic laboratory can design its own molecular biology experiments and has even made its first discoveries":

Artificial Intelligence Update

Researchers bring the ability to map the brain down to the expense and time frame of desktop computers:

http://www.physorg.com/news157733857.html

"Mapping the billions of connections in the brain is a grand challenge in neuroscience. The current method for mapping interconnected brain cells involves the use of room-size microscopes known as transmission electron microscopes (TEMs). Until now the process of mapping even small areas of the brain using these massive machines would have required several decades. In this week's open-access journal PLoS Biology, research teams at the University of Utah John A. Moran Eye Center and the University of Colorado at Boulder report technical advances that have reduced the time it takes to process high-speed "color" ultrastructure mapping of brain regions down to a few months."

Artificial Intelligence Update

Another step forward in the reverse engineering of the human brain?

http://www.physorg.com/news157717611.html

"Thirty-seven scientists from Cold Spring Harbor Laboratory (CSHL) and 20 other major research institutions in the U.S. and Europe have issued a major challenge to the neuroscience community. At long last, the time has come, they argue in a just-published paper, to assemble a comprehensive map of the major neural circuits in the mammalian brain."

MIT scientists have just figured out how to make the most popular AI image generators 30 times faster
