Newfound taste cells ‘multitask’ to sense it all

Researchers have found taste cells in mice that respond to as many as four different tastes. Humans are likely to have the same cells, the researchers say.

Synthetic odors created by activating brain cells help neuroscientists understand how smell works

Brains recognize a smell based on which cells fire, in what order – the same way you recognize a song based on its pattern of notes. How much can you change the 'tune' and still know the smell?

COVID-19, smell and taste – how is COVID-19 different from other respiratory diseases?

Many respiratory viruses cause us to temporarily lose our sense of smell. But SARS-CoV-2 isn't like those other viruses. Researchers are now exploring how it differs and whether patients recover.
