Researchers in India are developing a tampon that changes color if it detects a urinary tract infection. They soaked fibers in a substance that breaks down in the presence of Candida albicans, a common yeast infection, and placed them inside pads and tampons. In simulations, the fibers turned bright pink, indicating the presence of an … Read more
Death of the pelican crossing? New ‘smart’ traffic lights will automatically detect pedestrians and wait for slower people to cross the road using cameras and artificial intelligence Now Wireless developed technology so councils can programme traffic lights Artificial intelligence will be able to detect a pedestrian from 15 metres away System takes images from wide-angled … Read more
US scientists detect 55 chemicals in blood of pregnant women and their children that have never before been reported in humans and are linked to plastics and cosmetics – along with 42 ‘mystery’ compounds Scientists discovered 96 unique and strange chemicals in pregnant women The team found the chemicals in their blood and newborn babies … Read more
A British hospital is the first in the world to use a ‘sponge on a string’ to detect oesophageal cancer in a Covid-safe way. It allows health workers to collect cell samples from the food pipe without the need for an endoscopy, biopsy or sedation. Endoscopies, which involve passing a thin tube containing a camera … Read more
Forget painful nose swabs! Non-invasive SKIN tests can detect Covid-19 with 83% accuracy, scientists say Sebum is a waxy substance made by glands in the skin of the face, neck and back Researchers found the composition of lipids in the sebum is altered by Covid The difference in lipid levels was found to correlate with positive Covid … Read more

Scientists have created an algorithm that can accurately diagnose people with Covid-19 just by the sound of their cough. Their algorithm would underpin an app that could herald a quicker, cheaper and less invasive way of preliminary testing for the virus, according to the experts. DeepCough, created by experts from the University of Essex, was built … Read more
Scientists have created an algorithm that can accurately diagnose people with Covid-19 just by the sound of their cough. DeepCough, created by experts from the University of Essex, was built using 8,380 clinically-validated audio samples of people coughing. The samples were taken from hospitals in Spain and Mexico since April last year –2,339 who tested … Read more
It may be time to rewrite the textbooks, as scientists have discovered the Earth has a ‘fifth layer’ in the form of an innermost inner core at the centre of the planet. Geologists from the Australian National University created search algorithms allowing them to trawl through thousands of models of the Earth’s inner core. For … Read more
A small, wearable sensor that can detect levels of the stress hormone cortisol in sweat may soon help warn when people are nearing burnout, a study reported. Engineers at the Swiss Federal Institute of Technology Lausanne (EPFL) and start-up Xsensio said that the tool could help to objectively quantify stress levels. The device is placed directly … Read more
