Tiny island nations, Latin American developing countries and even non-joiners like Switzerland have all found more power and influence in climate negotiations after forming or joining a group.

Given two choices of attractive mates, female frogs pick the top vocalist. But add a third, inferior male to the mix, and females go for No. 2. The "decoy effect" shapes some human choices, too.

Dorothy Parker considered New York City her beloved hometown, but Parker's ashes can be found in Baltimore. Where were they before that? (This piece initially aired June 7, 2012 on Morning Edition.)

Scientists studying animals in their natural habitats can now just send in a drone with a camera, rather than trudging through rough terrain. But a new study finds that the drones don't go unnoticed.

Octopuses are cool. They can regrow lost arms, change the color of their skin, and are surprisingly smart. Scientists who sequenced the first octopus genome say it's nearly as big as a person's.

An international team of astronomers has measured the energy produced within a large portion of space more precisely than ever before, and their work shows how the universe is slowly dying.

Tigers have round pupils, but domestic cats have vertical slits in the center of their eyes. What gives? A census of the shapes of animals' pupils suggests size and way of life each play a big role.

Foraging bumblebees can pick up nearly half their weight in pollen before heading home to the hive, research shows. All that weight tucked into hollows on their hind legs can complicate flying.

Scientists who study bird behavior have made fake eggs to put in nests to see how birds react. This handicraft is going high-tech. (This piece first aired on May 26, 2015, on All Things Considered.)

The "new" dinosaur — named Wendiceratops pinhornensis — lived about 79 million years ago and helps scientists understand the early evolution of the family that includes Triceratops.

A clump of a mammoth's fur bought on eBay led scientists to a long list of ways the extinct species was special. One specific gene likely played a role in helping mammoths thrive in icy weather.

Speeches by high-level representatives were an attempt to keep momentum going as the world moves toward a key summit in Paris this year, which may produce an agreement to control greenhouse gases.
Monday, June 29, 2015
The United Nations is having a high-level climate meeting ahead of the end-of-year meeting in Paris that will hopefully result in a major new agreement to rein in greenhouse gases.

Scientists have figured out how massive chunks of ice trigger these seismically detectable events when they break off a glacier. The findings could help researchers track ice loss from glaciers.

The ribs of a 240 million-year-old fossil hold clues to how the first turtle shell evolved. And its skull shape seems closer to that of lizards and snakes than to an ancestor of dinosaurs and birds.

If a starfish loses a limb, a new arm buds and grows in its place. But young moon jellies have a different strategy for self-repair: Existing limbs rearrange themselves to regain symmetry.
Wednesday, June 10, 2015
Scientists say the Phoebe ring is "more than 200 times as big across as Saturn itself." They used a special infrared space telescope to get the best look yet at the massive ring of black dust.

Most tests for viruses aim to detect only one or two. But researchers can now check a drop of blood for antibodies to hundreds of viruses, tracing the history of a lifetime of infections, old and new.

The littlest things — punctuation, precise word choice and grammar — can hold tremendous power in worldwide climate negotiations. This year in Europe, editors get a chance to help make history.
