A network of devices called MERMAIDs is taking seismographs where they've never been.
- Most of the ocean floor is inaccessible to seismologists.
- Much can be learned about the interior of Earth by listening to earthquakes.
- Ingenious new floating sensors are changing the ocean seismology game.
Chinese scientists find a 600-million-year-old creature.
- Researchers in China find fossils of a creature that lived 600 million years ago.
- This creature resembles a modern-day comb jelly.
- If confirmed, these would be the oldest animal fossils discovered.
A completely unexpected discovery beneath the ice.
- Scientists find remains of a tardigrade and crustaceans in a deep, frozen Antarctic lake.
- The creatures' origin is unknown, and further study is ongoing.
- Biology speaks up about Antarctica's history.
We knew the Chicxulub crater was massive. We just didn't know how widespread the damage actually was.
- The asteroid that crashed into the Yucatan caused a mile-high tsunami.
- The wave was 52 times higher and 2,600 times more energetic than the 2004 Indian Ocean tsunami that killed over 227,000 people.
- Sediment was disturbed 3,700 miles from the site of the crash.
Tiny bubbles talk photosynthesis.
- During photosynthesis, algae produces a symphony of little "pings."
- The sounds are produced by oxygen bubbles breaking away from the plants.
- Monitoring reef health through its sound is a new avenue for acoustic ecology.
