Researchers here have discovered that a reddish deposit seeping out from the face of a glacier in Antarcticas remote Taylor Valley is probably the last remnant of an ancient salt-water lake. The lake probably formed as much as 5 million years ago when the sea levels were higher and the ocean reached far inland.

Ohio State University scientists reported their conclusions today at the annual meeting of the Geological Society of America in Seattle.
Berry Lyons, a professor of geological sciences and director of OSUs Byrd Polar Research Center, offered the best explanation to date for a strange, nearly-century-old discoloration halfway up the face of the Taylor Glacier in Antarcticas Dry Valleys. The Dry Valleys are well known to polar scientists who have studied these remarkably snow-free troughs leading from the Ross Sea onto the East Antarctic Ice Sheet.

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...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
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...
