(SCMP) – Dutch researchers have trained bees, which have an unusually keen sense of smell, to identify samples infected with Covid-19, a finding they said could cut waiting times for test results to just seconds.
To train the bees, scientists in the bio-veterinary research laboratory at Wageningen University gave them sugary water as a reward after showing them samples infected with Covid-19. They would get no reward after being shown a non-infected sample.
Having got used to the system, the bees were able to spontaneously extend their tongues to receive a reward when presented with an infected sample, said Wim van der Poel, a professor of virology who took part in the project.
