Tim Hanlon writes "Biofuels continue to lead the field in the search for a renewable, environmentally friendly replacement for crude oil. Besides its use in the transport industry, crude oil is also used to produce conventional plastics and chemical products such as fertilizers and solvents. Now chemists have learned how to convert plant biomass directly into a chemical building block that can be used to produce not only fuel, but also plastics, polyester, and industrial chemicals, cheaply and efficiently."

FEMA has decided to pull a children's coloring book entitled, "A Scary Thing Happened" from their website. The coloring book contained three images of the twin towers on fire for children to color. Rose Olmsted, the coordinator behind the book said, "I stand firm that it was a very well thought-out and useful resource for kids, but it's obviously being misinterpreted by a lot of people." Since people are so upset about the coloring book, I can only assume FEMA's plan for a human remains concentration game will be put on hold.

Hugh Pickens writes "While it may seem unlikely that single-celled organisms could be trained to salivate like Pavlov's dog at the sound of a bell, researchers say that bacteria can 'learn' to associate one stimulus with another by employing molecular circuits. This raises the possibility that bioengineers could teach bacteria to act as sentinels for the human body, ready to spot and respond to signs of danger. As with Pavlov's dog, the bacteria in the model learn to build stronger associations between the two stimuli the more they occur together. Now called Hebbian learning, it's often expressed as a situation in which 'neurons that fire together wire together.'" (More below.)

Roland Piquepaille writes "Dutch engineers have built the third generation of the DelFly autonomous air vehicle. The DelFly Micro made its first public flight earlier today in Delft. This micro air vehicle weighs only 3 grams and has a wingspan of 10 centimeters. This very small remote-controlled aircraft carries a 0.4 gram camera. The DelFly Micro, which looks like a dragonfly, can fly for 3 minutes at a maximum speed of 5 meters/second. It could be used for observation flights in difficult-to-reach or dangerous areas."
