Asian hornets have been spotted in the UK in record numbers this year, sparking concern about what their presence could mean for our native insects, and in particular bee populations. Madeleine Finlay speaks to ecologist Prof Juliet Osborne about why this species of hornet is so voracious, how European beekeepers have been impacted by their arrival, and how scientists and the government are attempting to prevent them from becoming established here.

Last week the founder of the dating app Bumble forecasted a near future dating landscape where AI ‘dating concierges’ filter out prospective partners for us. But does AI, or even science, really understand what makes two people compatible? Madeleine Finlay speaks to Amie Gordon, assistant professor of psychology at the University of Michigan, to find out what we know about why two people go the distance, and why she and her colleague associate professor of sociology Elizabeth Bruch, are designing their own dating app to learn more..

AI, algorithms and apps: can dating be boiled down to a science?

As AI systems have grown in sophistication, so has their capacity for deception, according to a new analysis from researchers at Massachusetts Institute of Technology (MIT). Dr Peter Park, an AI existential safety researcher at MIT and author of the research, tells Ian Sample about the different examples of deception he uncovered, and why they will be so difficult to tackle as long as AI remains a black box.

Backstabbing, bluffing and playing dead: has AI learned to deceive?

Sales of cottage cheese are booming thanks to a boost from protein-hungry social media influencers. But do we really need all this extra protein? Madeleine Finlay speaks to Joanne Slavin, a professor of food science and nutrition at the University of Minnesota, to find out what exactly protein is doing in our bodies, and what happens to it when we consume it in excess.

How much protein is too much?

A study has found that more than two dozen US coastal cities are sinking by more than 2mm a year. It’s a similar picture across the world. Nearly half of China’s major cities, as well as places such as Tehran and Jakarta, are facing similar problems. These issues are compounded by sea level rises caused by global heating. Madeleine Finlay speaks to Prof Manoochehr Shirzaei of Virginia Tech University and Prof Robert Nicholls of the University of East Anglia to find out what’s making our cities sink and whether anything can be done to rescue them from the sea.

Glioblastomas are an extremely aggressive type of brain tumour, which is why the news this week of a vaccine that has shown promise in fighting them is so exciting. And this comes right off the back of the announcement of another trial of the world’s first personalised mRNA vaccine for melanoma, a kind of skin cancer. Ian Sample talks to Prof Alan Melcher of the Institute of Cancer Research about how these vaccines work and whether they could one day be used to target cancer before it is even detectable on scans.
