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.

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.

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.

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?

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.

Researchers were surprised by what they found when they sandwiched a drop of water between two layers of an unusual two-dimensional material called graphene.
Saturday, March 21, 2015
Scientists outfitted some fake fungi with LEDs and put them in a Brazilian forest to test their theory that light, not some funky mushroom fragrance, was luring bugs.

Public passion is all well and good, but it will take more than big talk to get to Mars by 2025, space specialists say. Even several rockets' worth of cash won't easily solve the technical challenges.
Thursday, March 12, 2015
Scientists announced in a NASA teleconference that the biggest moon in our solar system has a salty ocean hidden below its icy surface.

Scientists have found some human DNA that, when added to mice, makes their brains bigger. But as DNA research into human brains goes forward, are there ethical lines we shouldn't cross?
