2023/05/30

Every year, the world’s leaders gather for the UN climate change conference. At Cop28, they will be faced with two stark warnings from scientists: we are likely to breach 1.5C warming above pre-industrial levels in the next five years, and we are on course to reach 2.7C of warming by the end of the century. Progress has never been more critical and this year it lies in the hands of the United Arab Emirates, a country that has plans to expand its already extensive oil and gas productions. With six

2023/05/23

We now know that global temperatures are likely to temporarily rise by more than 1.5C above pre-industrial levels in the next five years. Breaching this crucial threshold will give humanity an insight into what the next few decades could bring. It will undoubtedly have serious consequences in all aspects of our lives, including what we eat.

2023/05/09

Psychedelic drugs have long been been used for their mind-altering effects. Now, they are making their way into western medicine as a treatment for mental health disorders. From July, psychiatrists in Australia will be able to prescribe MDMA for post-traumatic stress disorder, making it the first country in the world to recognise psychedelics as medicines. The US could soon follow, with plans for the US Food and Drug Administration to be asked for approval to treat PTSD with MDMA this year. Ian

2023/05/04

For the first time, researchers have found a way to non-invasively translate a person’s thoughts into text. Using fMRI scans and an AI-based decoder trained on a precursor to ChatGPT, the system can reconstruct brain activity to interpret the gist of a story someone is listening to, watching or even just imagining telling. Ian Sample speaks to one of the team behind the breakthrough, the neuroscientist Dr Alex Huth, to find out how it works, where they hope to use it, and whether our mental privacy
