Elizabeth Blackburn shared the 2009 Nobel Prize in Physiology or Medicine with Carol Greider and Jack Szostak for their work on telomeres — the protective caps at the end of chromosomes — and for identifying the enzyme telomerase, which maintains telomere length. Now at the University of California, San Francisco, she offers Elena Tucker an insight into her life inside and outside academia.

Richard Roberts shared the 1993 Nobel Prize in Physiology or Medicine with Phillip Sharp for their discoveries of split genes, which contain parts that encode protein, called exons, and gaps between them, called introns. Now chief scientific officer at New England Biolabs based in Ipswich, Massachusetts, Roberts talks to Gijsbert Werner about microbes, genetically modified food and the problem with Nobel prizes.

Bruce Beutler is director of the Center for the Genetics of Host Defense at UT Southwestern in Dallas, Texas. He shared one half of the 2011 Nobel Prize in Physiology or Medicine with Jules Hoffmann for their work on the activation of innate immunity; the other half of the prize was awarded to Ralph Steinman. Here, Beutler talks to Christoph Thaiss about biological puzzles and intuition.

François Englert shared the 2013 Nobel Prize in Physics with Peter Higgs for the theoretical discovery of a mechanism that gives mass to subatomic particles. For this work, he collaborated with Robert Brout, who died in 2011. He looks back on his contribution to science with Thifhelimbilu Daphney Bucher.

A simple model captures the key features of the transition from smooth to turbulent flow for a fluid in a pipe. The findings pave the way for more-complex models and may have engineering ramifications. See Letter p.550

Authors: Nicola Harris
Acute infection of mice with an intestinal pathogen leads to long-lasting inflammation that is maintained by intestinal microorganisms. This observation reveals a path by which infection history can affect long-term immune function.

Tidal forces close to massive black holes can violently disrupt stars that make a close approach. These extreme events are discovered via bright X-ray and optical/ultraviolet flares in galactic centres. Prior studies based on modelling decaying flux trends have been able to estimate broad properties, such as the mass accretion rate. Here we report the detection of flows of hot, ionized gas in high-resolution X-ray spectra of a nearby tidal disruption event, ASASSN-14li in the galaxy PGC 043234. Variability within the absorption-dominated spectra indicates that the gas is relatively close to the black hole. Narrow linewidths indicate that the gas does not stretch over a large range of radii, giving a low volume filling factor. Modest outflow speeds of a few hundred kilometres per second are observed; these are below the escape speed from the radius set by variability. The gas flow is consistent with a rotating wind from the inner, super-Eddington region of a nascent accretion disk, or with a filament of disrupted stellar gas near to the apocentre of an elliptical orbit. Flows of this sort are predicted by fundamental analytical theory and more recent numerical simulations.
