The moment scientists had been dreading arrived late last year, when H5N1, or bird flu, was found for the first time in the Antarctic. Last week a king penguin on the island of South Georgia became the first in the region to be suspected to have died from the disease. The Guardian’s biodiversity reporter, Phoebe Weston, tells Ian Sample why researchers have said the spread of bird flu through the Antarctic’s penguin colonies could signal ‘one of the largest ecological disasters of modern...

If you’ve made a resolution to spend less time on your phone this year, help is at hand. The Guardian has launched a new newsletter, Reclaim your brain. Its co-writer and expert coach Catherine Price tells Madeleine Finlay how her own excessive phone use inspired her to investigate the science behind our relationships with our devices, and what we know about how to break the cycle. And Prof Barbara Sahakian of Cambridge University explains why many of us are drawn to looking at bad news on...

In November, a plane powered by 100% ‘sustainable’ jet fuel took off from London to New York. It was hailed by some as a milestone in reducing the carbon footprint of air travel, which accounts for about 2.5% of global CO2 emissions. Could this be the start of a greener way to fly? Madeleine Finlay speaks to Guy Gratton, associate professor of aviation and the environment at Cranfield University, to find out if the future of aviation can ever truly be guilt-free..
