We summarize the week's scientific breakthroughs every Thursday.
- Animals
Abandoned frog eggs can hatch early
If their father doesn’t keep them hydrated, frog embryos react by hatching early.
- Neuroscience
How brains filter the signal from the noise
Our brains can distinguish a single voice in the middle of a noisy street. A new study in ferrets shows how auditory systems might separate the signal from the noise.
- Genetics
E. coli’s mutation rate linked to cells’ crosstalk
When E. coli cells are in smaller crowds, their genes mutate at an increased rate.
- Plants
South American vine is a masterful mimic
The vine Boquila trifoliolata changes the shape of its leaves to match its host and avoid getting eaten.
- Life
1918 flu pandemic linked to human, bird virus gene swap
The 1918 pandemic flu, which killed up to 50 million people, may have come from a human virus and a bird virus swapping genetic material.
- Paleontology
‘Hidden dragon’ fossil is oldest flying reptile
Researchers have unearthed the oldest pterodactyl ever discovered: Kptodrakon progenitor soared over the Earth 163 million years ago.
- Genetics
Y chromosome gets a closer examination
The Y chromosome may play a larger role in Turner syndrome and in health and disease differences between males and females than previously thought.
- Animals
A guide to the world’s biggest flightless birds
A rhea on the loose in England has prompted warnings about approaching the bird. From ostriches to cassowaries, here’s your guide to friendly and unfriendly big birds.
- Climate
Glacial microbes gobble methane
While some bacteria produce methane in Greenland’s melting ice sheet, others may consume the greenhouse gas as it escapes.
- Animals
Frustrated fish get feisty
Smaller rainbow trout become more aggressive towards bigger fish when they don’t their usual treats.
- Genetics
Farmers assimilated foragers as they spread agriculture
While some European hunter-gatherers remained separate, others mated with the early farmers that introduced agriculture to the continent.
- Genetics
Gene therapy with electrical pulses spurs nerve growth
Deaf guinea pigs' hearing improves with electrical pulses from a hearing implant are combined with gene therapy, a new study shows.
