We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
Watch nerve cells being born in the brains of living mice
For the first time, scientists have seen nerve cells being born in the brains of adult mice.
- Ecosystems
Humans are overloading the world’s freshwater bodies with phosphorus
Human activities are driving phosphorus levels in the world’s lakes and other freshwater bodies to a critical point.
- Animals
It’s a bad idea for a toad to swallow a bombardier beetle
Toads are tough. But there are some insects even they shouldn’t swallow.
- Paleontology
This ancient creature looks like a spider with a tail
A newly discovered ancient creature looks like a spider and has silk spinners and spidery male sex organs.
- Plants
Pollinators are usually safe from a Venus flytrap
A first-ever look at what pollinates the carnivorous Venus flytrap finds little overlap between pollinators and prey.
- Neuroscience
A blood test could predict the risk of Alzheimer’s disease
A blood test can predict the presence of an Alzheimer’s-related protein in the brain.
- Animals
A peek into polar bears’ lives reveals revved-up metabolisms
Polar bears have higher metabolisms than scientists thought. In a world with declining Arctic sea ice, that could spell trouble.
- Animals
A killer whale gives a raspberry and says ‘hello’
Tests of imitating sounds finds that orcas can sort of mimic humans.
- Life
Here’s how cells rapidly stuff two meters of DNA into microscopic capsules
Scientists have figured out how cells quickly pack up their chromosomes before a cell divides.
- Animals
Slower speed, tricky turns give prey a chance against cheetahs and lions
A bonanza of data on wild predators running shows that hunting is more than sprinting.
- Animals
Here’s why so many saiga antelope mysteriously died in 2015
Higher than normal temperatures turned normally benign bacteria lethal, killing hundreds of thousands of the saiga antelopes.
- Earth
Life may have been possible in Earth’s earliest, most hellish eon
Heat from asteroid bombardment during Earth’s earliest eon wasn’t too intense for life to exist on the planet, a new study suggests.
