A group of researchers in Germany, led by Lorenz Meinel, has created an innovative molecular sensor capable of detecting flu through taste in the tongue, offering a fast, accessible and laboratory-free alternative to traditional diagnostic methods. According to the World Health Organization (WHO), the flu causes between 290,000 and 650,000 deaths each year, so having an early detection tool can be key to reducing serious contagions and complicat…
