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 future disease risks, based on their current medical record. While AI health prediction systems do exist, they typically only estimate risks for a single disease — the authors hope that their system could one day save healthcare professionals time and be used to calculate disease burdens at a population level.Research Article: Shmatko et al.News: What diseases will you have in 20 years?

Using a well-studied test of honesty, researchers looked to see if people were more likely to engage in unethical behaviour if given the option of delegating it to an AI. Including AIs seemed to increase the chance that someone would be dishonest, which raises concerns about the impacts of these tools on ethics.Research Article: Köbis et alNews and Views: People are more likely to cheat when they delegate tasks to AI24:54 Briefing ChatEurope has a new supercomputer, JUPITER, that could boost its AI ambitions, and a catalogue of octopus movement.Nature: World's most energy-efficient AI supercomputer comes onlineNew York Times: Building an Octopus Dictionary, One Arm Movement at a TimeSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

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 of Maryland about the quest to detect gravitational waves, which were first hypothesised by Albert Einstein back in 1916.

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 been “virtually impossible” without climate change, and that nearly a quarter of the heatwaves recorded from 2000 to 2023 can be directly linked to the greenhouse-gas emissions from individual energy giants.Research Article: Juvé et al.News and Views Forum: Heatwaves linked to emissions of individual fossil-fuel and cement producersNews: Dozens of heatwaves linked to carbon emissions from specific companies10:47 Research HighlightsHow shifting coastal tides may have spurred the rise of the world’s oldest civilization — plus, the liquid crystal lenses that can refocus in a flash.Research Highlight: Changing tides ushered in the world’s first civilizationResearch Highlight: Liquid-crystal specs refocus with the push of a button12:40 The growing resistance to the US war on scienceScience in the United States is facing an increasing crisis, in the face of swinging cuts and President Donald Trump’s ongoing attack on anything with a connection to diversity, equity and inclusion.

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.Cases like this are rare, but science is not immune to misconduct. The rise in 'paper mills' — organisations that produce questionable or fake papers that they sell authorships on — has led some to worry that misconduct is on the rise and that a proportion of the scientific literature cannot be trusted.In episode two of Self Correction, we explore how researchers are responding to the problem of research misconduct. We discuss how difficult it is to determine the prevalence of misconduct, and how sleuths, journalists and research integrity institutions are fighting back.This episode was written and produced by Nick Petrić Howe.

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. Nature reporter Mariana Lenharo visited the facility and told us all about her experience in this Podcast Extra.News: This is the world’s largest ‘mosquito factory’: its goal is to stop dengueVideo: Inside a mosquito factorySubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
