Nature is the international weekly journal of science: a magazine style journal that publishes full-length research papers in all disciplines of science, as well as News and Views, reviews, news, features, commentaries, web focuses and more, covering all branches of science and how science impacts upon all aspects of society and life.
In just 22 million years or so, hummingbirds have rapidly diversified from a single ancestor into more than 300 species, and some lineages are still generating new species at an extraordinary rate.Jimmy McGuire at the University of California, Berkeley, and his colleagues compared the
Sequencing the genome of an antibiotic-resistant microbe can identify the most dangerous isolates, reports a team led by Ruth Massey at the University of Bath, UK.Her group studied 90 isolates of methicillin-resistant Staphylococcus aureus (MRSA) that had varying levels of ability to stick
Researchers have uncovered how certain bacterial pathogens that infect plants make them sterile and capable only of spreading disease.Phytoplasma pathogens are transmitted by sap-feeding insects that turn flowers (such as Arabidopsis thaliana, pictured top) into leaf-like structures (bottom) that do not produce
A DNA-binding protein that regulates several genes also attaches to RNA, revealing another way in which the protein acts as a 'master weaver' of the genome.Félix Recillas-Targa of the National Autonomous University of Mexico in Mexico City, Danny Reinberg of New York University's Langone
Beneath Enceladus's south pole lies a watery ocean that could hold organic molecules that form the basis of life.Luciano Iess at the Sapienza University of Rome and his colleagues analysed gravity measurements from the Cassini spacecraft during three flybys of this moon of Saturn
Different kinds of El Niño warming events in the tropical Pacific Ocean can have widely varying effects on global temperatures.Simon Donner and Sandra Banholzer of the University of British Columbia in Vancouver, Canada, used historical sea surface temperature data to classify El Niño events
Genetically engineered poplars can make a modified polymer in their wood that breaks down more easily than natural forms. Such trees could one day be sources of biofuels.Current methods for digesting the tough, resistant polymer called lignin involve concentrated chemicals at high temperatures. John
A field experiment shows that wheat exposed to higher carbon dioxide levels converts less of the nitrogen it absorbs into protein. This could result in decreased food quality this century.Arnold Bloom at the University of California, Davis, and his colleagues compared nitrate concentrations and
Molecular 'robots' can perform complex logic tasks inside a living organism.Ido Bachelet of Bar-Ilan University in Ramat Gan, Israel, and his colleagues used folded strands of DNA to create a suite of nanorobots that open, close and coordinate with each other in response to
Highly read on iopscience.iop.org in MarchEven if the global temperature rise is held to a limit of 2 °C, most of Europe will probably warm by substantially more.A team led by Robert Vautard at the Pierre-Simon Laplace Institute in Gif-sur-Yvette, France, combined
The time lag between reporting a scientific discovery worthy of a Nobel prize and the awarding of the medal has increased, with waits of more than 20 years becoming common. If this trend continues, some candidates might not live long enough to attend their Nobel
Among many otherwise laudable suggestions, Mark Eisler and colleagues propose limiting feedstuffs for livestock to fibrous fodder, such as grass and silage (see Nature507, 32–34; 10.1038/507032a2014). However, we believe that any attempt to meet the rapid growth in
Mark Eisler and co-authors advocate eating only 300 grams of red meat a week (roughly the volume of three decks of playing cards) as a step towards producing sustainable livestock (Nature507, 32–34; 10.1038/507032a2014). That amount corresponds to
Zoos and aquaria worldwide attract more than 700 million visits every year. They are therefore well placed to make more people aware of the importance of biodiversity — a prime target of the United Nations Strategic Plan for Biodiversity 2011–20.We surveyed approximately 6,000 visitors
The gene CYLD is so named because one of its mutant forms is associated with cylindromatosis, which causes skin tumours.The CYLD protein is an enzyme; its active site in humans contains a cysteine residue at position 601 (denoted as C in the one-letter
The affiliation for Joshua Tewksbury in the Editorial ‘Natural decline’ (Nature508, 7–8; 2014) should have said he is director of the Luc Hoffmann Institute at the conservation group WWF in Gland, Switzerland.
A combination of laboratory experiments and modelling shows that diurnal temperature variations are the main cause of rock breakdown and the ensuing formation of powdery rubble on the surface of small asteroids. See Letter p.233
The MTH1 protein prevents oxidized nucleotides from being misincorporated into DNA. Two studies find that selective inhibition of MTH1 by small molecules suppresses tumour growth. See Articles p.215 & p.222
Africa had been thought to be a potentially large carbon sink — of great value in efforts to mitigate carbon dioxide emissions. But an analysis now reveals that it could be a net source of greenhouse gases that will increase global warming.
