We summarize the week's scientific breakthroughs every Thursday.
- Anthropology
Footprints offer clues about daily hominid life
Early male members of the human genus spent a lot of time together by the water, as their footprints attest.
- Neuroscience
Rats can navigate mazes, even when blind
Blind rats can learn to navigate with a compass and microchip prosthetic wired into their brains. Similar devices may one day help humans have super senses.
- Animals
Fossilized seashells’ true colors revealed
To the naked eye, fossilized seashells lack the colorful patterns of their living counterparts. But ultraviolet light can reveal some of their unique hues.

Heat makes scuttling tarantulas less coordinated
On hot days, tarantula run faster, but their may be harder to bend and flex at high speeds, researchers find.
- Health & Medicine
A more accurate prenatal test to predict Down syndrome
A test to detect genetic problems such as Down syndrome examines a baby’s DNA in the mother’s blood and may limit the need for more invasive screening.
- Animals
How human activities may be creating coywolves
Endangered red wolves will mate with coyotes when their partners are killed, which often happens because of human activities, a new study finds.
- Animals
Songbird crosses the Atlantic in a nonstop flight
Using light-sensing geolocators, researchers confirm an iconic songbird’s impressive transoceanic migration.
- Microbes
Some superbugs lurk in Britain’s surf
In Great Britain’s coastal waters, surfers and swimmers are exposed to low levels of drug-resistant E. coli, a new study finds.
- Humans
Egg-meet-sperm moments are equal opportunities for girls and boys
Despite previous claims, equal numbers of male and female embryos are conceived, new data suggest.
- Environment
Fracking chemicals can alter mouse development
Hormone-disrupting chemicals used in fracking fluid cause developmental changes in mice, new experiments show.
