The way forward is through Paris
Nature 527, 7579 (2015). doi:10.1038/527409a
Leaders must come together on a solid agreement at the United Nations climate conference — and then get to work at home by meeting commitments and finding new ways to reduce emissions.
Built on trust
Nature 527, 7579 (2015). doi:10.1038/527410a
Written agreements between parties in research collaborations are not a sign of a lack of faith.
A ‘perfect’ agreement in Paris is not essential

Success at the latest climate talks will be a recognition by the world’s nations that incremental change will not do the job, says Johan Rockström.
Zoology: Mollusc sees with its shell
Nature 527, 7579 (2015). doi:10.1038/527412a
A marine mollusc has hundreds of eyes in its armour that can see images.Christine Ortiz at the Massachusetts Institute of Technology in Cambridge and her colleagues studied the structural, optical and mechanical properties of the eyes of Acanthopleura granulata (pictured) using various experimental
Metabolism: Gastric surgery alters sweet tooth
Nature 527, 7579 (2015). doi:10.1038/527412b
Some weight-loss surgeries can diminish cravings for sweets by altering the brain's response to the neurotransmitter dopamine.Ivan de Araujo of Yale University in New Haven, Connecticut, and his colleagues studied the effects of a duodenal–jejunal bypass, which reroutes food from the stomach directly into
Ecology: Toads saved from killer fungus
Nature 527, 7579 (2015). doi:10.1038/527412c
Biologists have rid a wild toad species of a lethal fungal disease that threatens amphibians around the world.The chytrid fungus Batrachochytrium dendrobatidis has wiped out many species of frogs and toads. Jaime Bosch at Spain's National Museum of Natural History in Madrid and
Hydrology: Snow-fed water supply threatened
Nature 527, 7579 (2015). doi:10.1038/527412d
The southwestern United States, the Iberian Peninsula and parts of the Middle East and other regions are at risk of seasonal water shortages resulting from decreasing snowfall in a warming climate.Justin Mankin at Columbia University in New York and his colleagues looked at projections
Nutrition: Personalized diets for health
Nature 527, 7579 (2015). doi:10.1038/527413a
People who eat identical meals display different blood glucose levels afterwards, thanks in part to differences in their gut microbes.Large spikes in blood glucose after eating increase the risk of type 2 diabetes, so dietary guidelines rank foods based on their glycaemic index —
Quantum metrology: Lasers reveal quantum jitters
Nature 527, 7579 (2015). doi:10.1038/527413b
Ultrafast laser pulses can be used to detect the motion of a single atom, from energetic wiggles to quantum jitters.Kale Johnson at the University of Maryland in College Park and his colleagues trapped ions of ytterbium and zapped them with laser pulses just 10
Bioelectronics: Flower given digital power
Nature 527, 7579 (2015). doi:10.1038/527413c
Researchers have incorporated electronic circuitry into the tissues of a rose.Magnus Berggren at Linköping University in Norrköping, Sweden, and his colleagues submerged the cut end of a rose stem into a water-based solution of PEDOT, a conducting polymer that is used in printable electronics.
Agricultural ecology: Complex effects of pesticides on bees
Nature 527, 7579 (2015). doi:10.1038/527413d
Honeybee colonies could be compensating for the harmful effects of certain pesticides by producing more workers, at least in the short term.Some European countries banned neonicotinoid pesticides in 2013, but this remains controversial because field studies have failed to confirm the adverse effects reported
Planetary science: Martian moon will break apart
Nature 527, 7579 (2015). doi:10.1038/527413e
Phobos, one of Mars's two moons, will disintegrate some 20 million to 40 million years from now, and its particles will form the only planetary ring in the inner Solar System.Benjamin Black and Tushar Mittal of the University of California, Berkeley, made these predictions

Gene editing: Heed disability views
Nature 527, 7579 (2015). doi:10.1038/527446a
Author: Tom Shakespeare
CRISPR–Cas9 is a gene-editing tool of great potential, although not necessarily from a disability-rights perspective (see D. J. H.Mathewset al. Nature527, 159–161; 201510.1038/527159a). People with disabilities are, in my view, unlikely to be queuing up
