Scientists reassemble the backbone of life with a particle acceleratorynchrotron X-rays
Scientists have been able to reconstruct, for the first time, the intricate three-dimensional structure of the backbone of early tetrapods, the earliest four-legged animals. High-energy X-rays and a new data ...

Predicting fatigue: Nanocrystals reveal damaged material
A small crack in a metal wheel caused Germany's worst-ever rail accident—the 1998 Eschede train disaster. The problem: it was practically impossible to detect damage of that nature to a metal by inspecting ...

A method is now available to produce non-aggregating semiconducting particles in water
Conversion of water into hydrogen is a fundamental reaction powered by light, but the lack of suitable artificial drivers, or photocatalysts, for this reaction has hampered its commercial development. Platinum-decorated ...

Shift to shore: New model shows extinct tetrapod Ichthyostega couldn't walk
Palaeontology has gone high-tech: no more wax and plaster-cast models. Instead, 3D data from computed tomography (CT) scans is overturning long-held views of how the earliest land animals moved.

Lungfish provides insight to life on land
A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals. This innovation gave rise to the tetrapods—four-legged ...

Fossil footprints give land vertebrates a much longer history
The discovery of fossil footprints from early backboned land animals in Poland leads to the sensational conclusion that our ancestors left the water at least 18 million years earlier than previously thought. ...

Fossils suggest earlier land-water transition of tetrapod
New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to landlubber.
