We summarize the week's scientific breakthroughs every Thursday.
- Animals
Nature has a dog problem
Free-roaming dogs spread disease, kill wildlife by the thousands and have even caused extinctions. But their full effect on the environment has been little studied.
- Animals
Primitive signs of emotions spotted in sugar-buzzed bumblebees
When bumblebees eat a sugary snack, they make more optimistic decisions, a new study finds. This could be early evidence for emotion in insects.
- Genetics
Gene linked to autism in people may influence dog sociability
DNA variants were linked to beagles’ tendency to seek human help.
- Paleontology
Ancient microbe fossils show earliest evidence of shell making
Armor-plated, 809-million-year-old fossilized microbes discovered in Canada are the oldest known evidence of shell making.
- Animals
New case emerging for Culex mosquito as unexpected Zika spreader
The much-debated proposal that a Culex mosquito could help spread Zika gets some international support.
- Genetics
First ‘three-parent baby’ born from nuclear transfer
The first human baby produced through spindle nuclear transfer was born in April, New Scientist reports.
- Animals
Barnacles track whale migration
The mix of oxygen isotopes in the shells of barnacles that latch on to baleen whales may divulge how whale migration routes have changed over millions of years.
- Genetics
New era of human embryo gene editing begins
Gene editing of viable human embryos is happening, in and out of the public eye.
- Health & Medicine
It’s time to retire the five-second rule
Wet food can slurp bacteria off the floor in less than a second.
- Plants
Narrowed plumbing lets flower survive summer cold snaps
Ice barriers help alpine plants save their flowers during summer cold snaps.
- Genetics
Endurance training leaves no memory in muscles
Unlike strength training, endurance workouts left no genetic trace months later, calling into question idea of a general muscle memory.
- Earth
Natural ally against global warming not as strong as thought
Soils may take in far less carbon by the end of the century than previously predicted, exacerbating climate change.
