Scientists observe nanosize microtubules 'treadmilling' across plant cells
...kes treadmilling a really unexpected mechanism for assembling higher-ordered structures," Shaw observed. What guides the microtubule to its new orientation? The researchers hope that subsequent experiments will provide the answer. "When a microtubule is crawling along the surface of the cell, how does it know ...Texas A&M, Ecor Corp. sign deal to produce health-related proteins

Plans call for protein production facilities to be constructed in Weslaco, he said, where Mirkov and a proCANE researcher, Martin Yassi, now share labor...Discovery of proteins necessary for HIV release suggests possible new therapeutic targets
... of specific cellular proteins that are crucial to assembling HIV, Dr. Sundquist is providing potential new targets for future anti-HIV drugs. For example, he and his colleagues were the first to show that a protein called TSG101 is required for HIV release. HIV needs TSG101 in order to escape from its host c...From slime to saviors: Sorting out the fungal family tree
... the university's $510,000 share of the grant. "In assembling the family tree of fungi, our team will look at multiple genes and structural characteristics across a broad spectrum of fungi and put them in a database. Here at the University of Minnesota, we're studying the very finest elements of structure." "G...Researchers warn biotech advances could be misused by terrorists
