Two tongue tips are better than one – an evolutionary biologist explains why snakes have forked tongues.
Who’s a good doggie? Sniffer dogs might one day be able to screen people for COVID-19 in large crowds. But not when they’re hungry or need a good lie down.
A transcript of episode 10 of The Conversation Weekly podcast, including a story on a new technique to prevent predators eating the eggs of endangered birds.
Not all flowers smell good, to people at least, but their scents are a way to attract pollinators.
An expert in olfaction explains the effects of long-term smell loss, the subtle role the sense plays in our lives and resources for those affected.
Scientists are experimenting with using dogs to sniff out people infected with COVID-19. But dogs aren’t the only animals with a nose for disease.
COVID-19 patients often lose their sense of smell and taste. This is rare for a viral infection. At-home smell tests could be used as a screening tool and help slow the spread of the coronavirus.
Dogs process the sensory world very differently than humans, but love in a way that is entirely familiar.
Hyperosmia is relatively rare, but there are many reasons a person might develop this condition – even temporarily.
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?
Is it possible that people who recover from COVID-19 will be plagued with long term side effects from the infection? An infectious disease physician reviews the evidence so far.
The good news is: you’ll probably get it back.
Imagine being able to detect a smell from more than a kilometre away. Dogs can sniff out things from a greater distance than that.
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.
Mmmmmmm. That smells delicious. Wait, how do you know that?
There is abundant evidence that a sudden loss of smell is related to COVID-19.
All of the senses have been affected by the coronavirus pandemic, not because the senses have changed, but because the world has, writes a sensory historian.
Patients who later test positive for COVID-19 are reporting early loss of smell and taste. Researchers are now trying to understand if this could be an early sign of the disease.
Researchers are currently looking into these reports to confirm whether loss of smell is an early indication of COVID-19.
Infections like coronavirus can kill the nerves that let you smell, but they’ll usually grow back within weeks.
