How to make robots that we can trust

We are witnessing dramatic advances in the deployment of autonomous systems, but are we designing robots that can be trusted?
The analysis of large amounts of ice from Antarctica’s Taylor Valley has helped scientists to tease apart the natural and human-made sources of the potent greenhouse gas methane. Hinrich Schaefer

Antarctic ice reveals that fossil fuel extraction leaks more methane than thought

Analysis of 12,000-year-old Antarctic ice reveals that methane leaks from fossil fuel extraction play a larger role than previously thought.

Climate change set to increase air pollution deaths by hundreds of thousands by 2100

A new study suggests climate change will cause changes to patterns of ground-level ozone and smog – two deadly pollutants set to increase deaths by about 260,000 worldwide by the end of the century.

How trade policies can support global efforts to curb climate change

Climate change will have a big impact on the global economy, for better or worse. We explore four issues that bring climate and trade negotiations head to head.

The flightless, nocturnal and sweet-smelling kākāpō was thought to be extinct, but during the 1970s, two remnant populations were discovered. One, in Fiordland, included only males. From Wikimedia Commons

Plant hormone boost for New Zealand’s critically endangered night parrot

New research suggests that New Zealand’s bizarre nocturnal parrot, the kākāpō, needs plant hormones to breed successfully.

More reason to use Meningococcal B vaccine – it could also cut the Clap

As the WHO calls for urgency to address antibiotic resistance in gonorrhoea, new research shows that a vaccine developed against an unrelated disease offers protection.
Climate teams: if countries pooled resources, they could support a low-emission transformation.

A new approach to emissions trading in a post-Paris climate

New Zealand is a trailblazer for emissions trading, which could help drive a low-emission transformation, both domestically and overseas, in a post-Paris world.
