Ocean sciences: Farmed salmon swim to freedom
Nature 512, 7514 (2014). doi:10.1038/512234a
Vastly more salmon could be escaping from aquaculture farms (pictured) than is officially reported, say Ove Skilbrei and his colleagues at the Institute of Marine Research in Bergen, Norway.Farmed salmon that escape could mate with wild populations and make them less fit for survival.
HIV: Antibody–drug mix stops relapse
Nature 512, 7514 (2014). doi:10.1038/512234b
A combination of antibodies and multiple virus-activating drugs can keep HIV from resurging in infected mice, even after treatment ends.During drug treatment, HIV enters a dormant state and stays hidden inside infected cells; afterwards, it bounces back. A team led by Michel Nussenzweig at

Virology: Secret to Ebola's success
Nature 512, 7514 (2014). doi:10.1038/512235d
The Ebola virus might elude immune responses by stopping a key protein in infected cells from activating defence genes.Ebola, which kills up to 90% of people it infects, is known to disrupt the activity of interferon, a crucial antiviral protein. Gaya Amarasinghe at Washington
Engineering: Robot swarms take shape
Nature 512, 7514 (2014). doi:10.1038/512235e
A thousand-strong army of coin-sized robots (pictured) can arrange itself into various configurations.Michael Rubenstein and his co-workers at Harvard University in Cambridge, Massachusetts, programmed 1,024 robots with a simple set of rules and an image of a shape to be formed. Four

Author: Barbara Kiser
As a concept, sustainability is now near-ubiquitous. But is it a “buzzless buzzword”, as environmentalist Bill McKibben has opined? Historian Jeremy Caradonna writes that, on the contrary, this dynamic ethos has plenty of buzz. Predicated on joined-up thinking (such as the idea that society, economy
Non-native species: UK bill could prompt biodiversity loss
Nature 512, 7514 (2014). doi:10.1038/512253a
Author: Sarah Durant
The UK government's proposed Infrastructure Bill for England and Wales gives new powers to control or eradicate invasive, non-native species (see go.nature.com/kbkvtt). However, what constitutes such a species needs careful definition to ensure that any use of these powers is beneficial for conservation.The
