As the recipients of the 2013 science Nobel prizes gather in Stockholm to celebrate and be celebrated, News & Views shares some expert opinions on the achievements honoured.
Our knowledge of how Earth's natural satellite formed is increasingly being challenged by observations and computer simulations. Two scientists outline our current understanding from the point of view of the satellite's geochemistry and its early dynamical history.

Proliferation-driving mutations in haematopoietic stem cells often result in the loss of stem-cell properties. But at least one common oncogenic mutation seems to enhance both proliferation and stem-cell self-renewal. See Letter p.143
Ketolide antibiotics have been found to induce a ribosomal frameshift — a change in the way that RNA is translated — in bacteria. This promotes the expression of a gene for antibiotic resistance, and may have broader implications.
Large panels of human cancer cell lines have been profiled at the DNA, RNA and pharmacological levels to accelerate the search for cancer therapies. But two of those large data sets show only partial concordance. See Analysis p.389
Detailed observations of an intermittent ultraluminous X-ray source indicate that its emission is unlikely to be powered by mass accretion onto an intermediate-mass black hole as previously thought. See Letter p.500
Analysis of a meteorite found in northwest Africa, prosaically named NWA 7533, indicates that it is the first sample of the regolith, or 'soil', of Mars, and is derived from the earliest Martian igneous crust yet identified. See Letter p.513
The shifting nature of positive and negative feedbacks in a woodland region invaded by an exotic grass sheds light on the complexity of managing natural systems. See Letter p.517
After three decades of unsuccessful efforts to develop small molecules that neutralize the cancer-causing Ras proteins, an approach has been found that opens up fresh avenues for anticancer research. See Letter p.548
In a bacterial population, some cells stay single and motile, whereas others settle down and form chains. A study now investigates the mechanisms that determine these outcomes. See Article p.481
Breaking waves place repeated loading on marine algae, which can lead to death by fatigue. But observations of one alga suggest that its joint structure, which lacks transverse connections, confers fatigue resistance.
