Biotechnology startup Koniku is developing high-tech sensors to sniff out bombs. The device, a "Konikore", is made from living biological cells -- like the ones found in your nose -- that can smell molecular compounds. In December, trials of the device at international airports will begin. Koniku is also investigating whether the device could be used to detect Covid-19.

Airports around the world are increasingly testing out biometric identification, verifying a flier's identity through fingerprints or facial features. For instance, Delta Air Lines has installed facial recognition technology at the check-in kiosks, counters, checkpoints and boarding gates of a number of US airports. The company stresses that the system is optional for customers and that all biometric data is kept secure.
