Hello Nature readers, Today we laud a Nobel prize for the developers of lithium-ion batteries, learn why deep-learning AIs are so easy to fool and explore how to overcome impostor syndrome.

Chemistry Nobel for world-changing batteries The Nobel Prize in Chemistry has been awarded to John Goodenough, Stanley Whittingham and Akira Yoshino for the development of lithium-ion batteries. All three contributed to the development of the kind of lightweight, rechargeable batteries that power most of our gadgets — and make "possible a fossil fuel-free society", the Nobel chemistry committee said. Goodenough, a solid-state physicist, becomes the oldest Nobel laureate ever at the age of 97. Nature | 3 min read

Kids' climate lawsuit to go before Alaska court Alaska's Supreme Court will hear arguments today to determine if a climate lawsuit brought by a group of young people can go to trial. The lawsuit aims to overturn a state law enacted in 2010 to promote fossil-fuel development. The Alaska case joins several other high-profile efforts to combat climate change by focusing on the legal rights of children, including a complaint submitted to the United Nations by a group including climate-strike founder Greta Thunberg and another that challenges the US government over rights enshrined in the US constitution.

Top scientists sound no-deal Brexit alarm Leading scientists in the United Kingdom are sending strong warnings about the chilling effect on science if the country leaves the European Union without agreements on funding and research collaborations. Top among their concerns is uncertainty about whether scientists will be able to access the huge pot of money known as Horizon Europe. "In science, a no-deal Brexit would be like a severe drought for an orchard. You can't expect to have a harvest after watering it again next year. All the trees are already dead," said Nobel laureate Andre Geim, who discovered graphene. The Guardian | 6 min read

Why deep-learning AIs are so easy to fool Deep neural networks are part of daily life, running everything from automated telephone systems to your Netflix recommendations. Yet altering inputs — in the form of tiny changes that are typically imperceptible to humans — can flummox the best of them. And when they are piloting self-driving cars or diagnosing disease, that can lead to substantial problems. Nature | 15 min read

Chat with Nobel prizewinner Didier Queloz Yesterday, astronomer Didier Queloz was awarded a share in the 2019 Nobel Prize in Physics for his research on exoplanets. Shortly after the announcement, reporter Benjamin Thompson went tochat to him about the discovery that led to the prize, and where his field is headed. Nature | 8 min listen

How to overcome impostor syndrome The perfectionism developed by many scientists-in-training can fuel a tendency to amplify criticism over praise, writes neuroscientist and clinical psychologist Desiree Dickerson. She shares how she dials down her own self-doubt by developing a compassionate inner voice and challenging the behaviours — avoidance, procrastination — that feed the feeling of failure.

Don't miss your PhD deadline Crashed hard drives, printing snafus and writer's block are among the hurdles to getting your hard-won PhD thesis submitted on time. "In 15 years of working with PhD candidates, I've never heard anyone say, 'It was totally fine,'" says university research trainer Inger Mewburn. Those who have been through disasters, or have helped others to overcome them, share their top tips to get you through submission day. Nature | 4 min read

QUOTE OF THE DAY "Robert Schrieffer solved a problem that had resisted the best minds in physics for more than 40 years, while riding the New York subway." Physicists Nick Bonesteel and Gregory Boebinger write about their colleague, J. Robert Schrieffer, who had his Nobel-prizewinning insight into the theoretical basis of superconductivity when he was just 25. Schrieffer died on 27 July, aged 88. (Nature)

Cosmologist James Peebles, who won the Nobel Prize in Physics yesterday, apparently eats an ice cream bar during his lectures, according to mathematician (and former student) Steven Strogatz. Now that's a strategy for success I can get behind. Send me your favourite habits of former profs — and any feedback on this newsletter — at briefing@nature.com.
