Announcement: Nature launches five new journals for 2017
Nature 541, 7636 (2017). doi:10.1038/541134a
Since Nature Genetics was launched in 1992, the stable of Nature research and review journals has grown significantly. This year they’ll be joined by five more — a launch rate that is unprecedented and unlikely to be repeated. These new online-only subscription journals are responding to positive
Microbiology: Bacterial explorers move fast
Nature 541, 7636 (2017). doi:10.1038/541136a
Bacteria that were long thought to be stationary are capable of rapid movement across surfaces when grown alongside yeast.Streptomyces bacteria are common in soil and generate many antibiotics. Marie Elliot at McMaster University in Hamilton, Canada, and her colleagues cultured Streptomyces venezuelae
Physiology: How alcohol ramps up hunger signals
Nature 541, 7636 (2017). doi:10.1038/541136b
Brain cells that regulate appetite and feeding are activated by alcohol, offering a possible explanation for why drinking can lead to overeating.Sarah Cains at the Francis Crick Institute in London and her colleagues exposed mice to alcohol for three days and found that the
Ecology: Invasive wild pigs spread across US
Nature 541, 7636 (2017). doi:10.1038/541136c
Eurasian wild pigs transmit disease and destroy crops in the United States, and are expected to spread throughout the country in the coming decades.The invasive wild pigs (Sus scrofa; pictured) compete with the country's native wildlife and cost the agricultural industry
Neuroscience: Age sees boost in facial recognition
Nature 541, 7636 (2017). doi:10.1038/541136d
The brain is thought to trim back neural connections as it develops, but scientists report that the region we rely on to recognize faces continues to increase in size into adulthood.Kalanit Grill-Spector at Stanford University in California and her colleagues measured the brains of
Cancer: 'Old' cells linked to drug side effects
Nature 541, 7636 (2017). doi:10.1038/541137a
Cancer chemotherapy causes a host of side effects, and a particular group of cells that have stopped dividing could be at the root of this problem.Chemotherapy drugs cause some healthy cells to stop dividing and become senescent, and such cells are thought to promote
Biomaterials: Silk gland mimic spins strong fibres
Nature 541, 7636 (2017). doi:10.1038/541137b
A device that recreates the conditions in spiders' silk-spinning apparatus has produced 1,000 metres of material that is tougher than other spun artificial spider silks.Anna Rising and Jan Johansson at the Swedish University of Agricultural Sciences in Uppsala and their colleagues used the bacterium
Medical devices: Mini machines deliver drugs
Nature 541, 7636 (2017). doi:10.1038/541137c
A small device with moving parts can release drugs and be wirelessly controlled after being placed in the body.Sau Yin Chin and Samuel Sia at Columbia University in New York and their colleagues used biocompatible hydrogels to build the device, which is just over
Conservation: Effects of wildlife trade mapped
Nature 541, 7636 (2017). doi:10.1038/541137d
Global maps that show where the impact of consumer demand for wildlife is felt most strongly could help to guide conservation spending and priorities.Daniel Moran at the Norwegian University of Science and Technology in Trondheim and Keiichiro Kanemoto at Shinshu University in Matsumoto, Japan,
Planetary science: Many collisions made the Moon
Nature 541, 7636 (2017). doi:10.1038/541137e
The Moon may have been formed not from one big cosmic smash, as the leading theory holds, but from multiple smaller collisions.Billions of years ago in the early Solar System, space debris would have collided with the young Earth. Using computer simulations, a team
