We summarize the week's scientific breakthroughs every Thursday.
- Ecosystems
Ambush Ants: Beware the moldy patch on that branch
Tiny tropical ants build shaggy platforms on plants and hide underneath them, poised to reach out and capture insects that may be far larger than themselves.
- Animals
Funny Walks: Cranes bob, bob, bob along when hunting
The jerky neck motions of a whooping crane may help it spot food by keeping its head motionless about half the time.
- Paleontology
Egg-Citing Discovery: Dinosaur fossil includes eggshells
The first-ever find of shelled eggs inside a dinosaur fossil bolsters ideas about the reptiles' reproductive physiology.
- Animals
Fish Din: Reef clamor attracts young fish settlers
When looking for a home, young fish seem to prefer a reef that's alive with the sounds of shrimp and fish rather than a quieter environment.
- Animals
DNA tells pigs’ tale of diverse ancestry
A genetic study indicates that pigs were domesticated in at least seven different parts of Asia and Europe, not in just two regions, as many researchers had assumed.
- Ecosystems
Quick Fix: How invasive seaweed repairs its wounds
Scientists have discerned the chemistry underlying the rapid wound-healing process in an invasive green alga that is wreaking havoc in the Mediterranean Sea.
- Animals
Why a turkey helps a pal find a mate
A new study shows how the classic idea of kin selection could explain why male turkeys cruise in pairs, even though only one of them will win a mate.
- Animals
Big Mimics: African elephants can learn to copy sounds
Two captive African elephants—one rumbling like a truck and the other chirping like a different elephant species—show they may be the first land mammals other than primates to learn vocal imitations.
- Paleontology
Old Softy: Tyrannosaurus fossil yields flexible tissue
Scientists analyzing fragments of a Tyrannosaurus rex's leg bone have recovered soft, pliable material, including structures that apparently are cells and blood vessels.
- Animals
Ant larvae sway to say, ‘Feed me!’
The most detailed study yet of body language of ant larvae translates a swaying motion as begging for food and a chance at a better future.
- Animals
Cops with Six Legs
Insects commit crimes against their colonies, and researchers are taking a closer look at how these six-legged criminals get punished.
- Animals
Vampires Run: Bats on treadmills show high-speed gait
The first test of vampire bats on a treadmill shows that they've evolved their own style of running.
