Some surprise headlines need a second look, but quirky studies can often have a significant impact.
From singing fish to anti-malarial soup, we take a look back at the stories which made readers do a double-take in 2019.
Grandma's miracle soup
In November, schoolchildren from London found their traditional family soups had antimalarial properties.
Researchers from Imperial helped the schoolchildren test their clear homemade broths, originating from all over the world, and found that several of them showed activity against the malaria parasite Plasmodium falciparum.
The test was designed to engage children in the idea that evidence is the difference between natural remedies and modern medicine. Now researchers hope that this study may lead to discovering new anti-malarial compounds.
