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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
