The future of Chinese research
Nature 534, 7608 (2016). doi:10.1038/534435a
To boost its research quality and innovation, China must strengthen its scientific foundations and let researchers — not policymakers — set the agenda for innovation and discovery.
Biophysics: Chameleons' sticky spit grabs prey
Nature 534, 7608 (2016). doi:10.1038/534438a
Adhesive mucus allows chameleons to snare insects with their long tongues.Pascal Damman at the University of Mons in Belgium and his colleagues collected mucus from the tongue pads of veiled chameleons (Chamaeleo calyptratus; pictured) and found that it is 400 times more
Metabolism: Bone hormone boosts exercise
Nature 534, 7608 (2016). doi:10.1038/534438b
A hormone released from bones enhances muscle function during exercise, giving old mice the capabilities of young ones.Gerard Karsenty of Columbia University Medical Center in New York City and his colleagues found that blood concentrations of a hormone called osteocalcin increased during aerobic exercise
Astronomy: Early galaxy has wisps of oxygen
Nature 534, 7608 (2016). doi:10.1038/534438c
Astronomers have detected oxygen in a 13-billion-year-old galaxy — the first time that the gas has been found at such an early stage of the Universe.A team led by Akio Inoue at Osaka Sangyo University in Daito, Japan, used the powerful Atacama Large Millimeter/submillimeter
Neuroscience: Smart birds have big brains
Nature 534, 7608 (2016). doi:10.1038/534438d
Birds that sing or use tools have about as many neurons in their brains as monkeys do.Pavel Němec at Charles University in Prague and his colleagues measured the brain size of birds from 28 species, and counted the number of cells in the organs.
Neuroscience: Microbe makes mice social
Nature 534, 7608 (2016). doi:10.1038/534438e
Female mice that eat a high-fat diet produce litters with social deficits that are linked to changes in the offspring's gut bacteria.Mauro Costa-Mattioli at Baylor College of Medicine in Houston, Texas, and his colleagues compared offspring from mothers that ate a high-fat diet with
Medical devices: Insect-eye camera peers inside gut
Nature 534, 7608 (2016). doi:10.1038/534439a
Mini cameras at the end of a probe that are designed to 'see' like an insect's compound eye could eventually be used in medical endoscopes.Ömer Cogal and Yusuf Leblebici at the Swiss Federal Institute of Technology in Lausanne built a dome-shaped device measuring 10
Therapeutics: Antibody double trouble for HIV
Nature 534, 7608 (2016). doi:10.1038/534439b
Genetically engineered human antibodies that bind to two targets on HIV could one day be used to treat and prevent the disease.'Broadly neutralizing' antibodies can block various HIV strains, but the virus can overcome them by changing the viral protein that the antibodies recognize.
Organic chemistry: Plastic waste turned into fuel
Nature 534, 7608 (2016). doi:10.1038/534439c
Plastic from bottles and bags can be degraded into liquid fuels and waxes using available catalysts.Polyethylene is the world's most common plastic, but is difficult to break down, typically requiring temperatures higher than 400 °C. A team led by Zheng Huang at the Shanghai
Ecology: A climate refuge for trees
Nature 534, 7608 (2016). doi:10.1038/534439d
Forests in northeastern North America (pictured) could thrive in a warmer climate.How trees will react to a warmer environment is unclear; low average temperatures hamper their growth but higher temperatures can limit water availability. Loic D'Orangeville of the University of Quebec at
Neurobiology: Mitochondria make nerves grow
Nature 534, 7608 (2016). doi:10.1038/534439e
Enhancing the mobility of energy-producing structures called mitochondria in injured neurons helps these cells to regenerate in mice.After an injury, some young neurons can regrow their long signalling arms known as axons, but mature cells cannot. Zu-Hang Sheng of the National Institutes of Health
