 NatureSynchronized lasers measure how light changes matter How matter responds to light lies at the core of vision, photosynthesis, solar cells, and many other fields of scientific and practical import. But until now, it hasn't been possible to see just how light does it. A team led by scientists at Lawrence Berkeley National Laboratory has used SLAC's Linac Coherent Light for the first demonstration that x-ray and optical wave mixing reveals both structure and evolving charge states on the atomic scale.

Nature CommunicationsMagnetic vortex reveals key to spintronic speed limit Spintronics use electron spin to write and read information. To mobilize this emerging technology, scientists must understand exactly how to manipulate spin as a carrier of computer code. Now, scientists at Brookhaven Lab have precisely measured a key parameter of electron interactions called non-adiabatic spin torque that is essential to the development of spintronic devices. This unprecedented precision guides the reading and writing of digital information and sets the spintronic speed limit.

Physical Review ECooled coal emissions would clean air and lower health and climate-change costs Refrigerating coal-plant emissions would reduce levels of dangerous chemicals that pour into the air -- including carbon dioxide by more than 90 percent -- at a cost of 25 percent efficiency, according to a simple math-driven formula designed by a team of University of Oregon physicists.

ChemCam laser first analyses yield beautiful results Members of the Mars Science Laboratory Curiosity rover ChemCam team, including Los Alamos National Laboratory scientists, squeezed in a little extra target practice after zapping the first fist-sized rock that was placed in the laser's crosshairs last weekend. Much to the delight of the scientific team, the laser instrument has fired nearly 500 shots so far that have produced strong, clear data about the composition of the Martian surface.

Nature MaterialsORNL researchers probe invisible vacancies in fuel cell materials Knowing the position of missing oxygen atoms could be the key to cheaper solid oxide fuel cells with longer lifetimes. New microscopy research from the Department of Energy's Oak Ridge National Laboratory is enabling scientists to map these vacancies at an atomic scale. Contact: Morgan McCorkle

NatureFuture memory A new class of organic materials developed at Northwestern University boasts an attractive but elusive property: Ferroelectricity. The crystalline materials also have a great memory, which could be very useful in computer and cellphone memory applications, including cloud computing. The very long crystals with desirable properties are made using just two small organic molecules that are extremely attracted to each other. The starting compounds are simple and inexpensive, making the lightweight materials scalable for technology applications.

Nano LettersSelf-charging power cell converts and stores energy in a single unit Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. The development avoids converting mechanical energy to electrical energy for charging a battery.

American Chemical Society's 244th National Meeting & ExpositionFueling nuclear power with seawater A new absorbent material may be able to soak up enough trace uranium in seawater to help fuel future nuclear power plants. Tests by the Department of Energy's Pacific Northwest National Laboratory showed the material, which was developed by Oak Ridge National Laboratory, can soak up more than two times the uranium than a similar material developed in Japan.

Nature ChemistrySpeeding the search for better carbon capture Berkeley Lab researchers helped develop the first computational model to accurately predict the interactions between flue gases and a special variety of the carbon dioxide-capturing molecular systems known as metal-organic frameworks. This new model should greatly accelerate the search for new low-cost and efficient ways to burn coal without exacerbating global climate change.

ChemCam laser sets its sights on first Martian target Members of the Mars Science Laboratory Curiosity rover ChemCam team have received the first photos from the instrument's remote micro imager. The successful capture of ChemCam's first 10 photos sets the stage for the first test bursts of the instrument's rock-zapping laser in the near future. Contact: James E. Rickman

ScienceNew form of carbon observed A team of scientists led by Carnegie's Lin Wang has observed a new form of very hard carbon clusters, which are unusual in their mix of crystalline and disordered structure. The material is capable of indenting diamond. This finding has potential applications for a range of mechanical, electronic, and electrochemical uses. The work is published in Science on Aug. 17.

NatureGood vibrations Using a unique optical trapping system that provides ensembles of ultracold atoms, Berkeley Lab scientists have recorded the first direct observations of distinctly quantum optical effects -- amplification and squeezing -- in an optomechanical system. Their findings point the way toward low-power quantum optical devices and enhanced detection of gravitational waves among other possibilities.

Nature PhotonicsNano, photonic research gets boost from new 3-D visualization technology For the first time X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample. This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro- and nano-electronics. This new technique also reduces "guesswork" by eliminating the need for modeling-dependent structural simulation often used in X-ray analysis.

Nature MaterialsUnraveling intricate interactions, 1 molecule at a time In a key step towards the design of better organic electronic devices, a Columbia Engineering team has succeeded in performing the first quantitative characterization of van der Waals interactions at metal/organic interfaces at the single-molecule level. In a study published Aug. 12 in Nature Materials, the researchers reveal the existence of two distinct binding regimes in gold-molecule-gold single-molecule junctions, using molecules containing nitrogen atoms at their extremities that are attracted to gold surfaces.

Nature PhotonicsWorld's most powerful X-ray laser beam refined to scalpel precision With a thin sliver of diamond, scientists at the DOE's SLAC National Accelerator Laboratory at Stanford have transformed the Linac Coherent Light Source into an even more precise tool for exploring the nanoworld. The improvements yield laser pulses focused to higher intensity in a much narrower band of X-ray wavelengths, and may enable experiments that have never before been possible.

Nature CommunicationsNew phenomenon in nanodisk magnetic vortices New findings from a team of Berkeley Lab and Japanese scientists suggest that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well. A study at the Advanced Light Source revealed that contrary to suppositions, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon.

Nature CommunicationsMolecular economics: New computer models calculate systems-wide costs of gene expression Bioengineers at the University of California, San Diego have developed a method of modeling, simultaneously, an organism's metabolism and its underlying gene expression. In the emerging field of systems biology, scientists model cellular behavior in order to understand how processes such as metabolism and gene expression relate to one another and bring about certain characteristics in the larger organism.
