Animal behaviour: Videos teach tricks to wild monkeys
Nature 513, 7517 (2014). doi:10.1038/513146a
Wild monkeys can learn new behaviours by watching instructional videos — a feat that had previously been accomplished only in the laboratory.Tina Gunhold at the University of Vienna and her collaborators recorded video of two captive marmosets (Callithrix jacchus) as they opened
Genomics: How coffee got its buzz
Nature 513, 7517 (2014). doi:10.1038/513146b
The coffee plant makes caffeine using different genes from those found in tea and cacao, suggesting that the ability to produce the stimulant evolved at least twice in plants.Victor Albert at the University of Buffalo in New York and his colleagues sequenced the genome
Evolution: Wooing frogs are bat bait
Nature 513, 7517 (2014). doi:10.1038/513146c
Bats use echolocation not only to navigate, but also to spot and capture male frogs that are in the act of courting.Many male frogs inflate their vocal sacs while sending out calls to attract potential mates. Wouter Halfwerk at the Smithsonian Tropical Research Institute
Physics: Magnets used in suspension act
Nature 513, 7517 (2014). doi:10.1038/513146d
Researchers have developed a way to handle small objects in three dimensions using magnetic levitation, even when the objects themselves are not magnetic.George Whitesides and his team at Harvard University in Cambridge, Massachusetts, suspended a non-magnetic nylon screw in a liquid that becomes magnetic
Marine ecology: Blue whales bounce back
Nature 513, 7517 (2014). doi:10.1038/513147a
A population of blue whales has reached pre-whaling levels and is no longer endangered.Cole Monnahan at the University of Washington in Seattle and his colleagues modelled a population of blue whales (Balaenoptera musculus) in the eastern North Pacific along with the number
Microbiology and immunology: Early diet shapes gut flora
Nature 513, 7517 (2014). doi:10.1038/513147b
Breast- and bottle-fed monkeys develop distinct immune systems and communities of gut microbes.Populations of gut flora vary among adult primates, but little is known about what drives these differences. Dennis Hartigan-O'Connor of the University of California, Davis, and his colleagues found that breast-fed rhesus
Neuroscience: Music training aids speech processing
Nature 513, 7517 (2014). doi:10.1038/513147c
The more music training children receive, the better their brains become at distinguishing between similar speech sounds.Nina Kraus at Northwestern University in Evanston, Illinois, and her colleagues studied children aged six to nine years from low-income neighbourhoods in Los Angeles, California, who took part
Biofuels: Bacteria generate propane gas
Nature 513, 7517 (2014). doi:10.1038/513147d
Genetically engineered bacteria could one day be harnessed to make renewable propane fuel.Patrik Jones at Imperial College London, Kalim Akhtar at University College London and their colleagues introduced genes for various enzymes from different species of bacteria into Escherichia coli, so that the
Zoology: Archer fish show how to sharpshoot
Nature 513, 7517 (2014). doi:10.1038/513147e
Archer fish can control the water jets they shoot from their mouths to nab prey from a variety of distances.Peggy Gerullis and Stefan Schuster at the University of Bayreuth in Germany trained the fish (Toxotes jaculatrix; pictured) to fire at specific
The language of deception
Nature 513, 7517 (2014). doi:10.1038/513147f
A PLoS ONE paper on language patterns in fraudulent papers has sparked social-media speculation about new ways to spot dishonest work. Researchers at Cornell University in Ithaca, New York, took advantage of a singular resource to study the linguistics of fraud: the collected

Nature 513, 7517 (2014). http://www.nature.com/doifinder/10.1038/513157a
Author: Andrew Curry
Using a wildlife version of fitness trackers, biologists can finally measure how much energy animals need to stay alive.
Curing blindness: Vision quest
Nature 513, 7517 (2014). http://www.nature.com/doifinder/10.1038/513160a

Climate policy: Rethink IPCC reports
Nature 513, 7517 (2014). doi:10.1038/513163a
Authors: Thomas F. Stocker & Gian-Kasper Plattner
Voluntary work alone cannot sustain the assessments carried out by the Intergovernmental Panel on Climate Change. Thomas F. Stocker and Gian-Kasper Plattner call for institutional support and a longer report cycle.
Economics: Manufacture renewables to build energy security
Nature 513, 7517 (2014). doi:10.1038/513166a
Authors: John A. Mathews & Hao Tan
Countries should follow China's lead and boost markets for water, wind and solar power technologies to drive down costs, say John A. Mathews and Hao Tan.
Science fiction: Verne and beyond
Nature 513, 7517 (2014). doi:10.1038/513169a

Best-selling science-fiction writer Neal Stephenson's works cover everything from cryptography to Sumerian mythology. Ahead of next year's novel Seveneves, he talks about his influences, the stagnation in material technologies, and Hieroglyph, the forthcoming science-fiction anthology that he kick-started to stimulate the next generation of engineers.
