Aeolian (wind-borne) sediments in the upper part of the Kopanskaya Svita (basal Triassic) at Elshanka, near Buzuluk, on the south-western margin of the Urals, European Russia. Dr Richard Twitchett (University of Plymouth) prepares to make measurements.
The biggest mass extinction of all time happened 251 million years ago, at the Permian-Triassic boundary. Virtually all of life was wiped out, but the pattern of how life was killed off on land has been mysterious until now. A team from Bristol University and Saratov University, Russia, have now laid the evidence bare.
The Bristol and Russian researchers have documented the event in Russia after looking at 675 specimens of amphibians and reptiles from 289 areas spanning 13 successive geological time zones in the South Urals basin. The study will be reported in Nature, Thursday, November 4.
The mass extinction at the Permian-Triassic boundary is accepted as the most profound loss of life on record. Records indicate a loss of 50 per cent of animal groups or more, in both sea and on land, with a loss of 80 to 96 per cent of species. Local and regional-scale studies of marine specimen confirm the loss, but the terrestrial record has been harder to analyse in such close detail.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
