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.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
