Scientists have grave concerns over ethical and societal impacts of facial-recognition technology. In this surveillance special, we dig into the details.In this episode:03:24 Standing up against ‘smart cities’Cities across the globe are installing thousands of surveillance cameras equipped with facial recognition technology. Although marketed as a way to reduce crime, researchers worry that these systems are ripe for exploitation and are calling for strict regulations on their deployment.Feature: Resisting the rise of facial recognition17:44 The ethics of researching facial recognition technologyDespite concerns surrounding consent and use, researchers are still working on facial recognition technology. Can this sort of work be justified? We hear some of the debates going on in academia about this field of research.Feature: The ethical questions that haunt facial-recognition research25:02 What do researchers actually think?Nature surveyed 480 researchers who have published papers on facial recognition, AI and computer science. The results revealed that many researchers think there’s a problem.Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

New fossil finds and new techniques reveal evidence that early animals were more complex than previously thought.The Cambrian explosion, around 541 million years ago, has long been regarded as a pivotal point in evolutionary history, as this is when the ancient ancestors of most of today’s animals made their first appearances in the fossil record.Before this was a period known as the Ediacaran – a time when the world was believed to be populated by strange, simple organisms. But now, modern molecular research techniques, and some newly discovered fossils, are providing evidence that some of these organisms were actually animals, including ones with sophisticated features like legs and guts.This is an audio version of our feature: These bizarre ancient species are rewriting animal evolution Hosted on Acast.

Researchers try to unpick the complex relationship between sensory pollutants and bird reproduction, and how to combat organised crime in fisheries.In this episode:00:46 Sensory pollution and bird reproductionLight- and noise-pollution have been shown to affect the behaviour of birds. However, it’s been difficult to work out whether these behavioural changes have led to bird species thriving or declining. Now, researchers have assembled a massive dataset that can begin to give some answers. Research article: Senzaki et al.10:17 CoronapodInterim results from a phase III trial show compelling evidence that a coronavirus vaccine candidate can prevent COVID-19. However, amid the optimism there remain questions to be answered – we discuss these, and what the results might mean for other vaccines in development.
