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.
The launch of the first Sentinel satellite heralds an era in which detailed data on everything from earthquakes to urbanization will be freely available to anyone interested in Earth’s future.

Russia deserves to be sanctioned, but halting scientific collaboration is not the way to do it.

Two Nature papers signal new roles for this ancient metal in catalysis and cancer therapy.

Researchers are well placed to explain concepts, but journalists will bring the critical scrutiny needed to integrate science in society, says Susan Watts.

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 week in science: Chile hit by magnitude-8.2 quake; US unveils most accurate atomic clock; and European Parliament votes for clinical-trial transparency.

Director resigns as just one clinical-trial award is made.

Early clinical-trial results show promise for targeting cancer-related biochemical pathways.

Questions raised over health effects of devices.

Expectations high as first European Sentinel satellite launches.

Agencies withhold grant money from researchers who do not make publications openly available.

Country’s science renaissance threatened as NATO and NASA suspend links.

Rescue bid launched to save Hainan gibbon from becoming first ape driven to extinction by humans.

With the Ganges–Brahmaputra delta sinking, the race is on to protect millions of people from future flooding.

Biomathematician Steve Horvath has discovered a strikingly accurate way to measure human ageing through epigenetic signatures.

As the Intergovernmental Panel on Climate Change asks how its assessment process should evolve, Dave Griggs argues for decadal updates and eased workloads.

Costs of carbon emissions are being underestimated, but current estimates are still valuable for setting mitigation policy, say Richard L. Revesz and colleagues.

Nathaniel Comfort applauds a nuanced history of genetic engineering's early years.

Stuart Pimm enjoys a fellow naturalist's first visit to sub-Saharan Africa, and the global lessons drawn from it.

Highlights of this season's releases

Scott Barrett examines a study probing the nexus between climate change and energy.

Giovanna Mallucci assesses the autobiography of Stanley Prusiner, the discoverer of prions.

Maryn McKenna finds much to digest in a warning about the demise of our bodily bacteria.

Robert Lue enjoys a deft study of online pedagogy.

Chris Nelder relishes a lively history of fracking that delves into the complexities.

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
