For decades, the Florida sack-bearer moth was hiding in plain sight among collections of other sack-bearer moths around the U.S. Ryan St Laurent

A newly rediscovered moth species in Florida may already be at risk

A newly discovered, rare species of moth appears to live only in the Florida scrub. Scientists hope that naming it will allow it to be protected.

Africa has the world’s greatest genetic diversity, yet it’s missing from research: we’re filling the gap

Most genetic studies focus on people from European ancestry. But Africa has the richest diversity and must be included in genetic databases.
Back in the day, how did Neanderthal men get on with Sapiens women? (From Néandertal nu. A comic book by Frédéric Bihel and Ludovic Slimak/©Odile Jacob, 2026)

A matter of taste: did Neanderthals really like Sapiens women?

A recent article published and widely read in Science revealed that Neanderthal men preferred “Sapiens” women, but it fails to tell the whole story.

Humans’ closest invertebrate ancestors date back much further than thought – how we discovered the fossils that show this

Did Earth’s major diversification event really happen in one sudden explosion? Our fossil discovery suggests not.

Mosquitoes carrying malaria are evolving more quickly than insecticides can kill them – researchers pinpoint how

Once-lethal insecticides now require concerningly high concentrations to effectively kill mosquitoes. Some mosquitoes are already immune to all classes of insecticides used to control malaria.

What was the very first plant in the world?

Plants changed the atmosphere, built soil and created ecosystems that allowed animals like us to thrive. But first they had to make their way from the water to the land.
Most people get acquainted with their appendix when it’s inflamed and about to rupture. Sebastian Kaulitzki/Science Photo Library via Getty Images

What does the appendix do? Biologists explain the complicated evolution of this inconvenient organ

The appendix has independently evolved at least 32 times across 361 mammalian species. What makes it an evolutionary darling when it’s more of a medical liability today?
