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

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
