‘Malicious use is already happening’: machine-learning pioneer on making AI safer
Yoshua Bengio, considered by many to be one of the godfathers of AI, has long been at the forefront of machine-learning research . However, his opinions on the technology have shifted in recent years — he joins us to talk about ways to address the risks posed by AI, and his efforts to develop an AI with safety built in from the start.

However, examination of the limb bones of a well-preserved Nanotyran
Bowhead whales can live for more than 200 years – this protein might be why

The protein, cold-induced RNA-binding protein, was shown to enhance repair of double stranded DNA breaks, a particularly troublesome kind of damage. The team showed that this protein could also extend the lives of Drosophila f

Advice on how to get good sleep is everywhere, with the market for sleep aids worth more than US$100 billion annually. However, scientists warn that online hacks and pricey tools aren’t always effective, and suggest that lessons learnt about the workings of a network of biological clocks found in the human body could ultimately lead to improved sleep.This is an a
Honey, I ate the kids: how hunger and hormones make mice aggressive
00:48 How hunger, hormones and aggression interact in mouse brainsResearchers have uncovered the neural mechanisms that underlie an aggressive behaviour in mice prompted by hunger and hormonal state. Virgin female mice can become aggressive towards mouse pups when they are food deprived, but it seems that the relevant amounts of pregnancy hormones, oestrogen and progesterone, also played a role.

This stereotype extends to the jobs that people perceive women do, with men being associated with roles such as CEO or he
Ancient viral DNA helps human embryos develop
00:50 How ancient viruses drive modern human developmentResearch suggests that ancient viral-DNA embedded in the human genome is playing a key role in early embryo development. Around 8% of our genome consists of endogenous retrovirus DNA — the remnants of ancient infections, but knowledge of their activity is limited. Now, a team show that these sequences are required for the correct development
Audio long read: Autism is on the rise — what’s really behind the increase?
In April, Robert F. Kennedy Jr held a press conference about rising diagnoses of autism, and said he would soon be announcing a study to find the responsible agent. Although Kennedy said that environmental factors are the main cause of autism, research has shown that genetics plays a bigger part. Also, the rise in prevalence, many researchers say, is predominantly caused b
How a dangerous tick-borne virus sneaks into the brain

In rare cases an infection can lead to serious neurological symptoms, but little was known about how the virus interacts with human cells. Now, a team show that a protein found on the outside of cells plays an important role in infection. In mouse exper

This AI tool predicts your risk of 1,000 diseases — by looking at your medical records
00:50 The AI tool that predicts disease riskResearchers have developed an AI tool that can calculate a person’s risk of developing over 1,000 different diseases, sometimes years in advance. The system, called Delphi-2M, was trained to identify patterns of disease progression using 400,000 people's health records from data repository the UK Biobank. This training allowed it to predict someone’s fut
Detecting gravitational waves
In 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time, known as gravitational waves. These waves were produced by the final spiral of two orbiting black holes that smashed into each other, sending ripples across the Universe. In this podcast, Benjamin Thompson speaks to Cole Miller from the University o
Feeling the heat: fossil-fuel producers linked to dozens of heatwaves
00:45 Attributing extreme heat events to major energy producersMajor energy producers increased the likelihood and intensity of heatwaves, according to research published in Nature. Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would have
Research misconduct: how the scientific community is fighting back
In 2016, Brian Wansink wrote a blog post that prompted scientific sleuths to investigate his work. They found evidence of data manipulation, and, after several news articles and two investigations by his institution, he would found to have committed misconduct, as defined by Cornell University. His work had been used to inform US policy around food, much of which has now been thrown into question.
Nature goes inside the world’s largest ‘mosquito factory’ — here’s the buzz
Raising mosquitoes to tackle disease might sound like an odd concept, but that’s what a facility in Brazil is aiming to do. Millions of mosquitoes are produced there every week, but these insects carry harmless Wolbachia bacteria that curbs their ability to spread deadly human viruses.
