We summarize the week's scientific breakthroughs every Thursday.
- Animals
Are your cats having fun or fighting? Here are some ways to tell
Certain behaviors indicate if your cats’ interaction is friendly, aggressive or something in between, a new study finds.
- Life
76 percent of well-known insects fall outside protected areas
Protected areas can provide safe havens for insects, but many existing ones fall short, a new study finds.
- Science & Society
Here are 7 new science museums and exhibitions to visit in 2023
The Grand Egyptian Museum is slated to open, as well as new exhibitions dedicated to space travel, the Galápagos Islands and more.
- Life
A new metric of extinction risk considers how cultures care for species
Conservation efforts should consider relationships between cultural groups and the species important to them, researchers argue.
- Animals
Prairie voles can find partners just fine without the ‘love hormone’ oxytocin
Researchers knocked out prairie voles’ oxytocin detection system. They weren’t expecting what happened next.
- Life
Birds that dive may be at greater risk of extinction
For birds, a diving lifestyle seems irreversible, evolutionarily speaking. The inflexibility possibly increases diving birds’ chances of going extinct.
- Life
Fossils suggest early primates lived in a once-swampy Arctic
Teeth and jawbones found on Ellesmere Island, Canada, suggest that two early primate species migrated there 52 million years ago.
- Paleontology
A bird with a T. rex head may help reveal how dinosaurs became birds
The 120-million-year-old Cratonavis zhui, newly discovered in China, had a head like a theropod and body like a modern bird.
- Animals
Some young sea spiders can regrow their rear ends
Juvenile sea spiders can regenerate nearly all of their bottom halves — including muscles and the anus — or make do without them.
- Animals
A rare rabbit plays an important ecological role by spreading seeds
Rabbits aren’t thought of as seed dispersers, but the Amami rabbit of Japan has now been recorded munching on a plant’s seeds and pooping them out.
- Animals
Chicken DNA is replacing the genetics of their ancestral jungle fowl
Up to half of modern jungle fowl genes have been inherited from domesticated chickens. That could threaten the wild birds’ long-term survival.
- Microbes
Scientists have found the first known microbes that can eat only viruses
Lab experiments show that Halteria ciliates can chow down solely on viruses. Whether these “virovores” do the same in the wild is unclear.
