We summarize the week's scientific breakthroughs every Thursday.
- Paleontology
Fossil footprints may put lizards on two feet 110 million years ago
Fossilized footprints found in South Korea could be the earliest evidence of two-legged running in lizards.
- Anthropology
In Borneo, hunting emerges as a key threat to endangered orangutans
Only small numbers of Bornean orangutans will survive coming decades, researchers say.
- Climate
Look to penguins to track Antarctic changes
Scientists say carbon and nitrogen isotopes found in penguin tissues can indicate shifts in the Antarctic environment.
- Genetics
Study debunks fishy tale of how rabbits were first tamed
A popular tale about rabbit domestication turns out to be fiction.
- Health & Medicine
Cutting off a brain enzyme reversed Alzheimer’s plaques in mice
Inhibiting an enzyme involved in the production of Alzheimer’s protein globs also made old globs, or plaques, disappear in mouse brains.
- Life
Shipping noise can disturb porpoises and disrupt their mealtime
Noise from ships may disturb harbor porpoises enough to keep them from getting the food they need.
- Genetics
Genes could record forensic clues to time of death
Scientists have found predictable patterns in the way our genetic machinery winds down after death.
- Animals
Even after bedbugs are eradicated, their waste lingers
Bedbug waste contains high levels of the allergy-triggering chemical histamine, which stays behind even after the insects are eradicated.
- Plants
Ancient ozone holes may have sterilized forests 252 million years ago
Swaths of barren forest may have led to Earth’s greatest mass extinction.
- Animals
Trove of hummingbird flight data reveals secrets of nimble flying
Tweaks in muscle and wing form give different hummingbird species varying levels of agility.
- Neuroscience
The wiring for walking developed long before fish left the sea
These strange walking fish might teach us about the evolutionary origins of our own ability to walk.
- 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.
