The prospect that the 'Earth summit' planned for June at Rio de Janeiro will be a monumental disappointment seems to have been strengthened by the planning meeting in New York over the past five weeks.
All the signs are that global ozone depletion is increasing. Ideas to mitigate the problem that at first glance may seem far-fetched deserve more serious consideration and a scientific process of evaluation.
Research opportunities are opening up for the long-neglected study of mycobacterium tuberculosis, a disease of poverty that is once again on the rise. TB is back.
Homology modelling software can predict the structure of a newly sequenced protein by incorporating conformational similarity information from related proteins for which atomic coordinates are known. Models built using structural data are more reliable than those based on sequence alignments alone.
A competent cell kit for improved protein expression, a new glycan release and preparation system for glycobiology research and a molecular modelling package that turns a desktop PC into a three-dimensional molecular modelling and analysis system - new tools for protein engineering.
