Reserve to cover 1.8m km will protect penguins, leopard seals, orca and blue whales

The UK government has thrown its weight behind the creation of the world’s biggest environmental sanctuary, covering a huge swathe of the Antarctic ocean.

The massive 1.8m sq km reserve – five times the size of Germany – would ban all fishing in a vast area of the Weddell Sea and parts of the Antarctic peninsula, safeguarding species including penguins, killer whales, leopard seals and blue whales.

Journalists grilled GOP politicians on climate change. It didn’t go well

Major climate science reports usually pass by largely unnoticed, but in the wake of the latest IPCC report a number of journalists laudably grilled Republican lawmakers about its findings. While their responses were predictably terrible, it’s nevertheless crucial for journalists to hold GOP politicians accountable for their climate denial and policy inaction. Donald Trump’s answers were particularly ignorant and nonsensical in his 60 Minutes interview with Lesley Stahl.

Lee Berger wins Frank Fenner prize for life scientist of the year while ANU emeritus professor Kurt Lambeck wins prime minister’s prize for science

The sudden crash of several frog species in Australia and central America between the late 1970s and 1990s was a global mystery. Six species were lost in Queensland alone. The prevailing wisdom was environmental factors must be to blame for their extinction. Could it be rising pollution? Or ultraviolet radiation from the growing hole in the ozone layer?

It turned out it was neither. A group of Australian scientists showed environmental change was not responsible, and in the process upended conventional thinking about what can trigger species loss. It started as a theory from Rick Speare, a Townsville-based doctor and vet: that an infectious disease was spreading north through Queensland, wiping out frog species as it went. He invited Lee Berger, a veterinary science graduate from the University of Melbourne, to join the investigation as a PhD candidate.
