Hans Larsson, a McGill University palaeontologist (located in Montreal, Canada), has found physical proof that Canadas Arctic regions once had a Jurassic era. Scientists have suspected that dinosaurs lived in Canadas great north eons ago, yet it remained an unproven theory, since no bones had ever been uncovered.
Not anymore. Larsson has discovered tyrannosaurus dinosaur bones, which until now, had only been located in Canadas Prairie Provinces, as well as in the Western United States. "We were able to clarify that dinosaurs – large predatory dinosaurs – and a great variety of plants lived in the High Artic," he says. "We found dinosaur remains, as well as fern and tree fossils," continues Larsson, who walked up to 25 kilometres per day for one month with his research team to locate bones during the summer of 2003 and 2004. "You wouldnt expect it, yet dinosaurs and a great variety of plants lived in the High Arctic 240 to 65 million years ago."
These were Larssons first Arctic expeditions. He has also visited Western Africa five times to seek out elusive dinosaur fossils. He says the work isnt easy. Artic digs meant hours of walking with heavy equipment, while African digs came with pounding sun and drinking bad water. Yet its all worth it. "The fact that I may bring new perspectives on ancient life is what keeps me going," he says.

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...
