In biology, as in construction, it’s all about having tools that fit
the job. Researchers at Rockefeller University have now created a tiny
tool, more than 10,000 times smaller than the diameter of a human hair,
capable of encasing single membrane proteins from living cells. The new
system, which resembles a nanoscale sushi roll, will allow
investigators to individually stimulate these key proteins with
specific molecules and signals in order to precisely define the
biological reactions that result.

Researchers at The Scripps Research Institute have developed a new
two-punch strategy against HIV and they have already successfully
tested aspects of it in the laboratory.
Their study, which appears this week in the Proceedings of the National Academy of Sciences
(PNAS), may re-energize attempts to create a preventive/therapeutic
vaccine against HIV, say the authors. To date, more than a dozen
candidate vaccines, which have attempted to raise immunity against the
spikey proteins on the viral envelope, have all failed in clinical
testing.
