& VIEWS———————-Ageing: Longevity hits a roadblock
pp410-411Increased expression of sirtuin proteins has been shown to
enhance lifespan in several organisms. New data indicate that some of
the reported effects may have been due to confounding factors in
experimental design. Here, experts discuss the significance of these
data for research into ageing. See Letter p.482David B.Lombard, Scott

science: Slippery when wetted pp412-413The slick interior of the pitcher
plant has inspired a slippery material possessing self-lubricating,
self-cleaning and self-healing properties. The secret is to infuse a
porous material with a liquid that repels oils and water. See Letter

biology: A yeast for all reasons pp413-414Scientists have begun to
overhaul a yeast’s genome to make it more stable, engineerable and
evolvable. Remarkably, the part-natural, part-synthetic yeast cells
function and reproduce without obvious ill effects. See Letter

physics: Single electrons take the bus p414Single-electron circuitry is
a promising route for quantum information processing. The demonstration
of single-electron transfer between two distant quantum dots brings this
technology a step closer. See Letters p.435 & p.439Takis

sequenced, and the results are revelatory. See Article p.419Michael

of a moon pp36-37The Moon’s cratered surface preserves the record of
