When termites are chewing on your home, your immediate thought probably isn't "I wonder how they digest that stuff?" But biologists have been gnawing on the question for more than a century. The key is not just the termite, but what lives in its gut. A multitude of genes from the microbes populating the hindgut of a termite have been sequenced and analyzed, and the findings reported today in the journal Nature.

Scientists at the California Institute of Technology have deciphered the activity of an area of the brain that could one day prove vital in the development of neural prostheses--within-the-brain implants that would translate thought into movement in paralyzed patients. The results of this study were published as the featured article in the November 8 issue of Neuron.

What are the ultimate limits to miniaturization? How small can machinery--with internal workings that move, turn, and vibrate--be produced? What is the smallest scale on which computers can be built? With uncanny and characteristic insight, these are questions that the legendary Caltech physicist Richard Feynman asked himself in the period leading up to a famous 1959 lecture, the first on a topic now called nanotechnology.

An unusual population of the darkest, most lightweight galaxies known has shed new light on a cosmic conundrum. Astronomers used the W. M. Keck Observatory in Hawaii to show that the recently uncovered dwarf galaxies each contain 99 percent of a mysterious type of matter known as dark matter. Dark matter has gravitational effects on ordinary atoms but does not produce any light. It accounts for the majority of the mass in the universe.

A team of American and Canadian scientists has devised a new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils. The first published tests with the method further support the view that atmospheric CO2 has contributed to dramatic climate variations in the past, and strengthen projections that human CO2 emissions could cause global warming.

Astronomers from the California Institute of Technology and the University of Cambridge have developed a new camera that produces much more detailed pictures of stars and nebulae than even the Hubble Space Telescope, and it does all this from here on Earth.
