Whale pee is an ocean bounty
Some migrating cetaceans move thousands of miles to their breeding grounds, where whale urine fertilizes ocean waters with valuable nutrients.

Analyze This: Moving frogs to new places helped an endangered species spread
Frogs resistant to a deadly fungus jump-started populations in these new areas.
- Ecosystems
Scientists Say: Ecosystem
The interplay between living things and the physical environment gives rise to Earth’s thriving, life-sustaining ecosystems.
- Space
Is the International Space Station too clean?
Testing surfaces on board the space station revealed low microbial diversity, something that’s been linked to health problems elsewhere.

Meet some of the longest-lived animals
Think a 100-year-old person is old? Not compared to the world’s longest-lived animals — some of which have lifespans of thousands of years.
- Oceans
The world’s largest coral is longer than a blue whale
Scientists found the coral off the coast of the Solomon Islands.

Underwater mountains in the Pacific Ocean may be home to 20 new species
A recent expedition to undersea mountain ranges off the coast of Chile revealed a new seamount and a rich world of deep-sea biodiversity.
- Animals
This frog is the world’s smallest known vertebrate
Neither fleas nor toads, Brazilian flea toads are almost flea-sized. These mini frogs are small enough to fit on a pinkie fingernail.
- Life
Has the Endangered Species Act saved species from extinction?
After 50 years, this landmark law has kept many species alive — but few wild populations have recovered enough to come off the “endangered” list.
- Oceans
Shading corals during midday heat can limit bleaching
Shading coral reefs during the sunniest part of the day may help corals survive marine heat waves.
- Earth
Analyze This: Tropical forests have gotten patchier
Although many of the world's forests have gotten less fragmented since 2000, tropical forests have gotten more chopped up, putting animals at risk.
- Math
Bees and wasps devised the same clever math trick to build nests
During nest building, these insects add five- and seven-sided cells in pairs. This helps their colony fit together hexagonal cells of different sizes.
