We summarize the week's scientific breakthroughs every Thursday.

Urban animals may get some dangerous gut microbes from humans
Fecal samples from urban wildlife suggest human gut microbes might be spilling over to the animals. The microbes could jeopardize the animals’ health.
- Neuroscience
Americans tend to assume imaginary faces are male
When people see imaginary faces in everyday objects, those faces are more likely to be perceived as male, a new study shows.
- Animals
An Arctic hare traveled at least 388 kilometers in a record-breaking journey
An Arctic hare’s dash across northern Canada, the longest seen among hares and their relatives, is changing how scientists think about tundra ecology.
- Animals
Scientists uncover the secret to fishing cats’ hunting success
Volunteers in India have helped to explain how one of the world’s semiaquatic wild cat species hunts.
- Animals
A ‘trapdoor’ made of muscle and fat helps fin whales eat without choking
An “oral plug” may explain how lunge-feeding fin whales don’t choke and drown as they fill their mouths with prey and water while eating.
- Animals
These tiny beetles fly fast thanks to wing bristles and a weird, wide stroke
Minuscule featherwing beetles have evolved a unique way of flying that lets them match the speed of beetles three times as big.
- Chemistry
A disinfectant made from sawdust mows down deadly microbes
Antimicrobial molecules found in wood waste could be used to make more sustainable, greener disinfectants.
- Animals
Scientists vacuumed animal DNA out of thin air for the first time
The ability to sniff out animals’ airborne genetic material has been on researchers’ wish list for over a decade.
- Genetics
A genetic analysis hints at why COVID-19 can mess with smell
People with some genetic variants close to smell-related genes had an 11 percent higher risk of losing their sense of taste or smell.
- Animals
Part donkey, part wild ass, the kunga is the oldest known hybrid bred by humans
Syria’s 4,500-year-old kungas were donkey-wild ass hybrids, genetic analysis reveals, so the earliest known example of humans crossing animal species.
- Animals
The largest group of nesting fish ever found lives beneath Antarctic ice
Researchers stumbled upon a fish breeding colony of unprecedented size, spanning a territory slightly larger than Baltimore.
- Animals
Female dolphins have a clitoris much like humans’
The similarities suggest female dolphins experience sexual pleasure, which may explain why the species is so randy all the time.
