"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg. "This will have important implications for various fields from climate modelling to human health." CFEL is a joint venture of Deutsches Elektronen-Synchrotron DESY, the German Max Planck Society and the University of Hamburg. Aerosol particles like soot play...

Laser probes microscopic components of air pollution Researchers at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles' surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important to climate change, as well as the design of cleaner combustion...

Sandia National Labs Scientist Arrested

Lee Rannals for redOrbit.com A Sandia National Labs scientist was arrested recently because he allegedly stole laboratory research and shared it with China. Jianyu Huang is being accused of stealing research belonging to the U.S. that he claimed was his own original research that he shared with several Chinese universities. He went online to share the data with the country's state-run schools. Sandia National Labs said that he did not have access to classified national security...

Precise Measurement Of Radiation Damage Identified
2012-06-06 06:55:26

Lawrence Livermore National Laboratory researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material. "A full understanding of the early stages of the radiation damage process provides knowledge and tools to manipulate them to our advantage," said Alfredo Correa, a Lawrence Fellow from Lawrence Livermore National Laboratory in the Quantum Simulations Group. Nuclear radiation leads to highly energetic ions that can...

A Sandia National Laboratories technology has been used to remove radioactive material from more than 43 million gallons of contaminated wastewater at Japan's damaged Fukushima Daiichi nuclear power plant. Sandia researchers had worked around the clock following the March 2011 disaster to show the technology worked in seawater, which was pumped in to cool the plant's towers. "It's the kind of thing that sends a chill," said Mark Rigali, manager of the geochemistry group at Sandia. "We've...

Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and the Notre Dame Radiation Laboratory at the University of Notre Dame used ultrafast spectroscopy to see what happens at the subatomic level during the very first stage of photosynthesis. "If you think of photosynthesis as a marathon, we're getting a...
