We summarize the week's scientific breakthroughs every Thursday.
- Animals
Fewer scavengers could mean more zoonotic disease
Scavenger populations are decreasing, a new study shows. That could put human health at risk.
- Humans
100 years after the Scopes trial, science is still under attack
In 1925, John Scopes was indicted for teaching evolution. Science News looks at the forces that led to the trial and how expertise was the big loser.
- Health & Medicine
A genetic test may predict which weight loss drugs work best for patients
Variants of obesity-related genes influence how much weight patients lose on specific weight loss drugs like liraglutide, two studies report.
- Animals
This spider’s barf is worse than its bite
Most spider species subdue dinner by injecting venom from their fangs. Feather-legged lace weavers swathe prey in silk, then upchuck a killing brew.
- Neuroscience
At early ages, autism in girls and boys looks similar
A new study of more than 2,500 children under 5 found little difference in autism symptoms between boys and girls.
- Animals
Preemptively cutting rhinos’ horns cuts poaching
Comparing various tactics for protecting rhinos suggests that dehorning them drastically reduces poaching.
- Animals
Probiotics helped great star corals fend off a deadly disease
A probiotic paste prevented the spread of stony coral tissue loss disease, but the treatment is still a proof-of-concept, not a cure.
- 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.
