Study: Race influences warfarin dose
(American Society of Hematology) A new report demonstrates that clinical and genetic factors affecting dose requirements for warfarin vary by race. The study, published online today in Blood, the Journal of the American Society of Hematology, proposes race-specific equations to help clinicians better calculate warfarin dosage.

Collision course: ONR testing high-speed planing hulls to better understand wave slam
(Office of Naval Research) Earlier this month, scientists sponsored by the Office of Naval Research performed experiments to better understand the motions, forces and pressures generated by waves on boats with high-speed planing hulls. Planing hulls are like those used on a speedboat -- they're designed to produce lift and allow the watercraft to glide on top of the water, skimming more quickly over its surface. At higher speeds, 'wave slam' become a problem.

Donuts, math, and superdense teleportation of quantum information
(University of Illinois College of Engineering) Quantum teleportation has been achieved by a number of research teams around the globe since it was first theorized in 1993, but current experimental methods require extensive resources and/or only work successfully a fraction of the time. Now, by taking advantage of the mathematical properties intrinsic to the shape of a donut -- or torus, in mathematical terminology -- a research team led by physicist Paul Kwiat of the University of Illinois at Urbana-Champaign has made great strides by realizing 'superdense teleportation.'

Aftershock assessment
(Inderscience Publishers) Earthquakes kill, but their aftershocks can cause the rapid collapse of buildings left standing in the aftermath of the initial quake. Research published in the International Journal of Reliability and Safety offers a new approach to predicting which buildings might be most susceptible to potentially devastating collapse due to the ground-shaking aftershock tremors.

Exciting new Canadian open access journal FACETS to launch, with Dr. Jules Blais as Editor
(Canadian Science Publishing (NRC Research Press)) FACETS -- a new multidisciplinary open access journal led by Dr. Jules Blais and published by Canadian Science Publishing -- will encompass a broad range of scientific areas and provide a high-quality, affordable Canadian open access option that well serves the publishing and dissemination needs of researchers in Canada and beyond.

Endless oscillations
(International School of Advanced Studies (SISSA)) According to classical physics, the universe tends to equilibrium but the same does not apply to quantum systems, which are destined to shift constantly between different configurations without ever finding peace. A theoretical study conducted by SISSA and the University of Oxford illustrates this dramatic difference and explains that in order to be described correctly one-dimensional quantum systems should be thought of as being defined on discrete points in space.

Deciphering dark and bright
(PLOS) The human sensory systems contend with enormous diversity in the natural world. But it has been known for a long time the brain is adapted to exploit statistical regularities that nonetheless arise amongst this diversity. Research publishing this week in PLOS Computational Biology reports that established statistical distributions of visual features, such as visual contrast, spatial scale and depth, differ between dark and bright components of the natural world.

Helping robots put it all together
(Massachusetts Institute of Technology) A new algorithm lets autonomous robots divvy up assembly tasks on the fly.

Understanding and controlling the propagation of waves
(Karlsruher Institut fr Technologie (KIT) ) The Karlsruhe Institute of Technology (KIT) has successfully acquired funding for a new collaborative research center (CRC). The German Research Foundation (DFG) will finance the CRC 'Wave Phenomena: Analysis and Numerics' coordinated by KIT. Here, mathematicians in the areas of analysis and numerics cooperate to analytically understand, numerically simulate, and manipulate the propagation of waves. In addition, the DFG has approved the new CRC/Transregio 'Waves to Weather.' It addresses a new generation of weather forecasts.

How spacetime is built by quantum entanglement
(University of Tokyo) A collaboration of physicists and a mathematician has made a significant step toward unifying general relativity and quantum mechanics by explaining how spacetime emerges from quantum entanglement in a more fundamental theory.
