- Satellites seeing clearly despite clouds
- Two researchers at Pacific Northwest National Laboratory PNNL have developed a mathematical tweak which dramatically improves air pollution detection on cloudy days. They've found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases. 'Because clouds represent one...

- Self-healing ceramics for nuclear safety
- Pacific Northwest National Laboratory PNNL researchers have used supercomputers to simulate how common ceramics could repair themselves after radiation-induced damages. This is an important discovery because 'materials that can resist radiation damage are needed to expand the use of nuclear energy.' These ceramics, which are able to handle high-radiation doses,...

- Growing metals on cotton
- Researchers at the Pacific Northwest National Laboratory PNNL have created a new form of metal crystals grown on cotton. Theyve used acid-treated cellulose fibers from cotton to crystallize them. Then, they grew all kinds of metal nanocrystals measuring between 2 and 200 nanometers on what they call "a cotton assembly...

- Cleaning uranium waste with bacteria
- Nuclear bombs can kill people even if they're not used. In the U.S. alone, the Department of Energy estimates that more than 2,500 billion liters of groundwater are contaminated with uranium as a consequence of nuclear weapons production. In "Uranium 'pearls' before slime," scientists from the Pacific Northwest National Laboratory...

- Bacteria can build nanowires
- Researchers at the Pacific Northwest National Laboratory PNNL have discovered that under certain conditions, some very common bacteria can form nanowires. These bacteria were able to produce nanowires as small as 10 nanometers in diameter, but which can reach hundreds of microns in length. What is interesting here is that...

- HP's newest supercomputer geared for energy and environment
- The newest supercomputer in town isn't for simulating nuclear explosions or the human brain, but rather take on arguably more pressing problems in areas such as climate science, hydrogen storage and molecular chemistry. Built by HP, the $21.4 million Chinook is a custom-made machine specifically designed for...

- Two-front attack on the snow in U.S. mountains
- There's been considerable written about the gradual warming of the earth's atmosphere and the shrinkinhg of glaciers and mountain snowpack. Now comnes research confirming there is a second man-made pollutant reducing mountain snowpack, directly affecting water supplies for urban areas from Denver to Los Angeles. Soot...

- Get Smart: Researchers call results of GridWise energy demand-response project encouraging
- If this blog takes the form of a news story, that's because it kinda is. In some ways this is a phenomenon I’ve been writing about for years -- the fact that headless devices like sensors and meters and intelligent appliances will start driving more traffic on the Internet than...

- 'Cooking' carbon nanotubes like spaghetti
- Scientists from the Pacific Northwest National Laboratory PNNL have developed a technique to force a variety of enzymes to self-assemble layer-by-layer on carbon nanotubes CNTs with the help of noodle-like polymer molecules. In "A biosensor layered like lasagna," the researchers say that this technique can be applied to a wide...
