We summarize the week's scientific breakthroughs every Thursday.
- Animals
The mysterious, extinct ‘Fuegian dog’ was actually a semi-tame fox
Historic European accounts long described the canids as domesticated dogs. A new study suggests that’s probably not true.
- Animals
The phoenix isn’t the only critter to survive the flames
There are no real phoenixes hiding anywhere. But science has revealed that some living things can take quite a bit of heat.
- Animals
Around the world, birds sing longer in light-polluted areas
In light-polluted landscapes, birds' singing time is an average of 50 minutes longer per day. It's still unclear if this hurts bird health or helps.
- Animals
Frilly bug feet inspire a water-striding robot
Ripple bugs’ nimble movements on the surface of water inspired a robot with automatically unfurling fans on its feet.
- Animals
These giant carnivorous bats hug, cuddle — and even share dinner
Infrared cameras in Costa Rica revealed that the world’s largest carnivorous bat maintains close social bonds through wing wraps and prey sharing.
- Health & Medicine
Could babies get bird flu through breast milk? Maybe, a study hints
H5N1 bird flu might infect human mammary glands, potentially allowing the virus to show up in breast milk.
- Animals
Streaked shearwaters poop only while flying over the ocean
In-flight defecation may help the birds stay away from feces that can contain pathogens such as bird flu while also fertilizing the ocean.
- Animals
A single protein makes lovesick flies spill their guts
Producing a male-specific protein in digestion-related neurons may have led to the evolution of an odd “romantic” barfing behavior in one species of fruit flies.
- Planetary Science
Cosmic rays could, in theory, sustain life on other worlds
The hypothesis could extend the search for extraterrestrial life to include frigid planets with thin atmospheres and underground water.
- Animals
Warm autumns could be a driver in monarch butterflies’ decline
In the lab, higher temperatures during fall migration led monarchs to break their reproductive pause, increasing their risk of death.
- Paleontology
Dinosaur teeth reveal some were picky eaters
The enamel in fossilized teeth reveals some dinosaurs preferred to eat particular parts of plants.

Squashing the spotted lanternfly problem may require enlisting other species
The invasive spotted lanternfly has spread to 17 states and can threaten vineyards. But bats, fungi, dogs and even trees may help control them.
