Green Microchips Are Faster
Researcher at Rice University, Krishna Palem has found that "pruning" away the little-used circuits on microchips can double the energy efficiency and computing speed of the chips.
Microchips installed in multimedia devices like hearing aids and cameras can be made more efficient and much faster by trimming off unnecessary portions of the circuitry. Accuracy in the devices, however, is reduced. "The result of this less-accurate computing process is much greater efficiency. By cleverly managing the probability of errors and by limiting which calculations produce errors, the designers have found they can simultaneously cut energy demands and boost performance."

Three scientists publish a paper proving that Mercury, not Venus, is the closest planet to Earth.
- Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
- Wrong! Neither Venus nor Mars is the right answer.
A new method of growing mini-brains produces some startling results.
- Researchers find a new and inexpensive way to keep organoids growing for a year.
- Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
- The mini-brains took control of muscles connected to the spinal cords.
