Fossil find fills in picture of ancient marine life

Paleontologists have discovered a rich array of exceptionally preserved fossils of marine animals that lived between 480 million and 472 million years ago, during the early part of a period known as the Ordovician. The specimens ...

Meteorites reveal warm water existed on Mars

New research by the University of Leicester and The Open University into evidence of water on Mars, sufficiently warm enough to support life, has been published this week in the journal Earth and Planetary Science Letters.

Four-legged jumping robots to explore the moon

A four-legged robot trained through artificial intelligence has learned the same lesson as the Apollo astronauts—that jumping can be the best way to move around on the surface the moon. An update on LEAP (Legged Exploration ...

Scientists crack mystery of the Sierra Nevada's age

In science, the simplest questions often prove themselves the most difficult to answer. Questions such as what killed the dinosaurs, or how many fish are there in the oceans took decades to solve or remain unanswered.

Study of northern Alaska could rewrite Arctic history

Parts of Alaska's mountainous Brooks Range were likely transported from Greenland and a stretch of the Canadian Arctic much farther to the east, according to a series of Dartmouth-led studies detailing over 300 million years ...

Ancient beavers cut trees for food first, not to build dams

Earth's Grand Canyon inspires awe for anyone who casts eyes upon the vast river-cut valley, but it would seem nothing more than a scratch next to the cavernous scar of Valles Marineris that marks the face of Mars.

Studying the moon's oldest geologic imprints

New Curtin research has found the moon may have been subjected to much greater impacts from asteroids and other bodies than previously thought, building on our understanding of the moon's earliest geologic evolution.

Clay may have been birthplace of life, new study suggests

Clay, a seemingly infertile blend of minerals, might have been the birthplace of life on Earth. Or at least of the complex biochemicals that make life possible, Cornell University biological engineers report in the Nov. 7 ...
