Scientists at the Kyoto Prefectural University in Japan discovered a novel way to detect coronavirus by using antibodies derived from ostrich eggs. Using face masks fitted with special filters, the researchers sprayed fluorescent dye containing the ostrich antibodies onto the masks. When the virus was present, the filters glowed bright green under ultraviolet light. "We can mass-produce antibodies from ostriches at a low cost," said Yasuhiro Tsukamoto, president of the team. "In the future, I want to make this into an easy testing kit that anyone can use."
