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.

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.

Faux eggs made with 3-D printers are better than sculpted versions, researchers say, because it's easier to systematically vary their size, weight and other features. Next goal: 3-D fragile shells.

Genetically, at least, not that much has changed in the billion years since you two last shared a relative. Roughly half the 500 genes yeast need for life are interchangeable with the human versions.
Tuesday, May 19, 2015
Genetic sleuthing and comparisons of recently discovered fossils with living snakes point to a "protosnake" ancestor that likely had tiny hind legs and lived about 120 million years ago.
Tuesday, May 12, 2015
Hoping to help trace the history of how velociraptors evolved into birds, researchers at Harvard and Yale may have tracked a key beak transformation to two genes.

It's a nightmarish job: No exercise or fresh air and little food and sleep for days at a time, all in an effort to persuade 200 countries to save Earth's climate and the planet. Can they do it?
Wednesday, May 06, 2015
Near a field of deep sea vents between Norway and Greenland, scientists discovered the DNA of microbes that seem to be primitive archaea, but with a lot more genes — typical of complicated creatures.
Monday, April 06, 2015
Some scientists suggest calling the era we live in the Anthropocene, to denote the time when humans came to dominate Earth's fate. But did it start with farming, the atom bomb or other event?
Monday, April 06, 2015
Leaders of what some call a new civil rights struggle say the protests must lead to long-term strategies. The goal is to sustain a national movement and to get past challenging obstacles.

During astronaut Scott Kelly's year in space, scientists will compare his physiology with that of his twin brother, Mark, to study the effect of prolonged space flight on the human body.
