We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Environment
Plastic pollution increases risk of devastating disease in corals
Researchers estimate about 11 billion pieces of plastic are polluting Asia-Pacific corals, raising the risk of disease at scores of reefs.
- Genetics
Scientists find 10 new defense systems used by bacteria
Scientists identify 10 groups of genes that appear to govern defense systems used by bacteria against virus attacks.
- Science & Society
Memory remains elusive, but the search continues
Acting Editor in Chief Elizabeth Quill explores the history of memory and scientists' search for its physical trace in our brains.
- Genetics
Baby macaques are the first primates to be cloned like Dolly the Sheep
Scientists have cloned two baby macaque monkeys with the same technique used to clone Dolly. The research could help advance the cloning of other species.
- Neuroscience
Somewhere in the brain is a storage device for memories
New technology and new ideas spur the hunt for the physical basis of memory.
