Leonardo fossil sketch may depict early nests

Posted on 16 Nov 2012 in Animal Behaviour, Earth Science, Featured, Journalism, Palaeontology

Around 500 years ago, Leonardo da Vinci briefly focused his attention on fossils – and triggered a mystery that remains unsolved. He sketched a honeycomb-like array of hexagons, the first recorded observation of the trace fossil Paleodictyon. New fossils could explain why we have never found the animal that makes Paleodictyon – and extend the fossil record of parental care. Image: mdwombat

Buddhist statue acquired by Nazis is meteorite fragment

Posted on 27 Sep 2012 in Archaeology, Earth Science, Featured, Physics, Space

One religious statue has a stronger connection than most to the heavens. An 11th-century carving from Mongolia of the Buddhist god Vaisravana was fashioned from a meteorite fragment, a chemical analysis shows. Its extraterrestrial origins make it unique in both religious art and meteorite science. Image: Elmar Buchner

Earth’s crust is cracking up under Indian Ocean

Posted on 26 Sep 2012 in Earth Science, Featured, Journalism

The whole world shuddered in sympathy back in April, as Earth’s crust began the difficult birth of a new tectonic plate boundary. Two huge earthquakes ripped through the floor of the Indian Ocean, triggering large aftershocks the world over, and providing the best evidence yet that the vast Indo-Australian plate is being torn in two.

Fossil raindrops reveal Earth’s early atmosphere

Posted on 28 Mar 2012 in Earth Science, Journalism, Physics

Some things never change. An analysis of a fossilised rain shower suggests air density on early Earth was broadly similar to today’s – and that makes it difficult to explain why Earth was warmer than it is now when the sun shone less brightly. Image: John-Morgan

Russian hot springs point to rocky origins for life

Posted on 13 Feb 2012 in Chemistry, Earth Science, Evolution, Featured, Journalism, Life

Where on Earth is the cradle of life? The widespread view is that life began in the oceans, in the water that surrounds deep-sea hydrothermal vents. But that story is being challenged by new evidence that life began on land, which is deepening a rift between origin-of-life biologists. Image: Anna S. Karyagina

Volcanoes may give a 100-year warning

Posted on 1 Feb 2012 in Earth Science, Journalism, Physics

A blast from the past has left tantalising hints that volcanic eruptions could be predicted decades in advance. Volcanoes can signal their intent to erupt days or months ahead of time, giving authorities a chance to evacuate the area. Now evidence of the events leading up to a Bronze Age eruption suggests it might be possible to extend that warning period. Image: miriam.mollerus
