Students build submarine to track Octopuses
Marine biologists want to find out more about the Giant Pacific Octopus, but this elusive creature doesn't willingly reveal its secrets. Divers can follow the octopus for short periods, but what's really needed is an undersea robot that will wait patiently outside the creature's den, ready to shadow its every move. University of Arizona engineering undergraduate students along with students from two other universities are building a mini-sub to answer this need.

Therapy for Alzheimer's in sight?
Immunoglobulins which are already being used to treat multiple sclerosis may also be able to help patients with Alzheimer's. This, at least, is the finding of a pilot study on five patients at the University of Bonn. The results are set out in the forthcoming edition of the Journal of Neurology, Neurosurgery and Psychiatry (vol. 75, pp. 1472-1474), which also devotes its editorial to this discovery.

22nd amino acid synthesized and added to genetic code of e. coli bacteria
Two years ago, researchers surprised the scientific community by announcing their discovery of a 22nd genetically encoded amino acid. Now they've successfully synthesized the amino acid - L-pyrrolysine - and shown that bacteria can incorporate it into new proteins - the biological components which do most of the work in cells. This explains exactly how the 22nd amino acid is incorporated into. The genetic instructions to put pyrrolysine into proteins follows a traditional path many scientists hadn't predicted.

Humans not irrational, just wary
Psychologists often conclude from research subjects' behavior in psychological experiments that humans are irrational. New research indicates that humans are in fact quite rational; they just do not trust what people in lab coats tell them.
