Climate warming likely to impact water resources in regions around the globe
Scientists at Scripps Institution of Oceanography at the University of California, San Diego, and their colleagues have produced the first clear evidence of human-produced warming in the worlds oceans, a finding they say removes much of the uncertainty associated with debates about global warming. In a new study conducted with colleagues at Lawrence Livermore National Laboratorys Program for Climate Model Diagnosis and Intercomparison (PCMDI),
Tim Barnett and David Pierce of Scripps Institution used a combination of computer models and real-world "observed" data to capture signals of the penetration of greenhouse gas-influenced warming in the oceans. The authors make the case that their results clearly indicate that the warming is produced anthropogenically, or by human activities. "This is perhaps the most compelling evidence yet that global warming is happening right now and it shows that we can successfully simulate its past and likely future evolution," said Tim Barnett, a research marine physicist in the Climate Research Division at Scripps. Barnett says he was "stunned" by the results because the computer models reproduced the penetration of the warming signal in all the oceans. "The statistical significance of these results is far too strong to be merely dismissed and should wipe out much of the uncertainty about the reality of global warming."

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...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
