New findings have suggested that adding sensors to supermarket trolleys could save people’s lives. Scientists investigated whether installing electrocardiogram (ECG) sensors – designed to check the heart’s rhythm – on the handles of supermarket, trolleys could identify shoppers with atrial fibrillation, which causes an irregular and often abnormally fast heart rate. The sensors would detect heart conditions that put them at increased risk of stroke. The researchers said that over the course of two months, they identified 39 people who were unaware that they had the condition. Ian Jones, professor of cardiovascular nursing at Liverpool John Moores University, who led the study, said: “That’s 39 people at greater risk of stroke who received a cardiologist appointment.” He added: “This study shows the potential of taking health checks to the masses without disrupting daily routines.” It is estimated that around 1.5 million people in the UK have atrial fibrillation, contributing to one in five strokes. The condition is treatable, but at least another 270,000 people in the UK remain undiagnosed and unaware, according to the British Heart Foundation.

Professor Jones said: “Nearly two-thirds of the shoppers we approached were happy to use a trolley, and the vast majority of those who declined were in a rush rather than wary of being monitored. “This shows that the concept is acceptable to most people and worth testing in a larger study.” He added: “Checking for atrial fibrillation while people do their regular shopping holds promise for preventing strokes and saving lives. “A crucial aspect is providing immediate access to a health professional who can explain the findings and refer patients on for confirmatory tests and medication if needed.” The findings were presented at ACNAP 2023 conference organised by the European Society of Cardiology (ESC).

A newly discovered species of beetle that has sex organs shaped like a bottle opener has been named Carlsberg after the beer giant. Many animals face an uncertain future thanks to changes to their habitats. So, when a brand new species is discovered it is an exciting thing for scientists. It allows experts an opportunity to get creative with the name, with some previous examples including a new rainbow fly species named after RuPaul and an ancient egg-laying mammal named after Sir David Attenborough. Now researchers from the University of Copenhagen have discovered six new South American beetle species of the rove beetle genus Loncovilius, one of which caught the eye. Because the insect’s penis was shaped like a bottle opener. The unusual shape led to researchers giving it the very apt name – Loncovilius carlsbergi. Biologist Aslak Kappel Hansen, from the Natural History Museum of Denmark, explained: “This species is characterised, among other things, by the fact that the male’s sexual organ is shaped remarkably like a bottle opener. "Therefore, we thought it is obvious to dedicate this species to the Carlsberg Foundation, which has generously supported independent research for many years. “Their support for various projects, expeditions, or purchase of the scientific instruments at the Natural History Museum of Denmark contributes to the discovery of new species on our planet.” Hansen explained that the beetles’ penises evolve to be differently shaped, allowing them to only reproduce with members of the same species. “As such,” Hansen explained, “they are often the best way to identify a species. That’s why entomologists like us are always quick to examine insect genitalia when describing a species. The unique shape of each species’ genitals ensures that it can only reproduce with the same species”.
