Why did the elephant cross the road? In Malaysia they are trying to find the answer
The body of an elephant calf lies on the side of a remote highway in the north of Peninsular Malaysia - the East-West Highway is flanked by two wildlife refuges, Royal Belum State Park and the Temengor Forest Reserve. It is stories like this in the Malaysian media that are of increasing concern to wildlife experts.

Evolution of Alpine landscape recorded by sedimentary rocks
Evolution of Alpine landscape recorded by sedimentary rocks
Rock avalanches and torrents started to form V-shaped valleys in the Alps approximately 25 million years ago. This landscape contrasts to the flat and hilly scenery, which characterized the Alps a few millions of years before. Geologists from the University of Bern applied digital technologies to unravel these changes in landscape evolution.

Journey to the Center of a White-Dwarf Star
Journey to the Center of a White-Dwarf Star
A stellar core that challenges predictions: here is the result of the first cartography of the interior of a white-dwarf star performed by an international team that includes  Valérie Van Grootel and Marc-Antoine Dupret , two researchers belonging to the STAR Institute at Université de Liège. This discovery will provide insights on the different physical mechanisms involved in the evolution of stars and our Sun.

Strong El Niño Events Cause Large Changes in Antarctic Ice Shelves
A new study published Jan. Geoscience reveals that strong El Niño events can cause significant ice loss in some Antarctic ice shelves while the opposite may occur during strong La Niña events. El Niño and La Niña are two distinct phases of the El Niño/Southern Oscillation (ENSO), a naturally occurring phenomenon characterized by how water temperatures in the tropical Pacific periodically oscillate between warmer than average during El Niños and cooler during La Niñas.

Which came first: complex life or high atmospheric oxygen?
Which came first: complex life or high atmospheric oxygen?
We and all other animals wouldn't be here today if our planet didn't have a lot of oxygen in its atmosphere and oceans. But how crucial were high oxygen levels to the transition from simple, single-celled life forms to the complexity we see today? A study by UC Berkeley geochemists presents new evidence that high levels of oxygen were not critical to the origin of animals.
