We summarize the week's scientific breakthroughs every Thursday.
- Animals
Flamingos create precise water vortices in a shrimp-hunting frenzy
Nashville Zoo flamingos reveal the oddball birds generate many types of vortices to eat. The swirls could be an inspiration to human engineers.
- Plants
Trees ‘remember’ times of water abundance and scarcity
Spruce trees that experienced long-term droughts were more resistant to future ones, while pines acclimatized to wet periods were more vulnerable.
- Animals
Aussie cockatoos use their beaks and claws to turn on water fountains
Parrots living in Sydney have learned how to turn on water fountains for a drink. It's the first such drinking strategy seen in the birds.
- Animals
How luna moths grow extravagant wings
Warm temperatures, not just predator pressure, may favor luna moths’ long bat-fooling streamers, a geographic analysis of iNaturalist pics shows.
- Animals
Genetics might save the rare, elusive saola — if it’s not already extinct
A new genetic study could help saolas survive by enabling better searches through environmental DNA. But some experts fear they may be extinct already.
- Health & Medicine
Personalized gene editing saved a baby, but the tech’s future is uncertain
The personalized CRISPR treatment could be the future of gene therapy, but hurdles remain before everyone has access.
- Neuroscience
‘Silent’ cells play a surprising role in how brains work
New studies show that astrocytes, long thought to be support cells in the brain, are crucial intermediaries for relaying messages to neurons.
- Animals
Bedbugs may have been one of the first urban pests
Common bedbugs experienced a dramatic jump in population size about 13,000 years ago, around the time humans congregated in the first cities.
- Life
The first cicada concert was 47 million years ago
A 47-million-year-old cicada fossil from Germany’s Messel Pit could teach us about the evolution of insect communication.
- Paleontology
Sloths once came in a dizzying array of sizes. Here’s why
A new fossil and DNA analysis traces how dozens of sloth species responded to climate shifts and humans. Just two small tree-dwelling sloths remain today.
- Climate
Penguin poop gives Antarctic cloud formation a boost
Penguin poop provides ammonia for cloud formation in coastal Antarctica, potentially helping to mitigate the impacts of climate change in the region.
- Animals
Juvenile capuchins are kidnapping infants of another monkey species
Over 15 months on Jicarón Island, researchers saw five capuchin juveniles abduct 11 endangered howler monkey infants — all for no clear purpose.
