Production resumes at Metropolis

World Nuclear News - 8 hours 51 min ago
Full production has resumed at Honeywell's Metropolis uranium conversion plant in Illinois after a uranium hexafluoride leak earlier this month. The leak was caused by over-pressurization of a system that was undergoing maintenance at the time.

http://www.cnsnews.com/news/article/penny-starr/back-school-feds-tell-teachers-push-renewable-energy-class-kids-can-save   Teachers heading back to the classroom will be adding renewable energy to the curriculum to mold future “energy leaders to save the planet,” thanks to a summer training program run by the Department of Energy (DOE) and the Smithsonian Science Education Academies for Teachers.   “By teaching the teacher, events like this one [...]

Former NOAA Meteorologist Says Employees ‘Were Cautioned Not To Talk About Natural Cycles’

Climate Depot - Wed, 08/26/2015 - 12:31
Former NOAA meteorologist David Dilley has submitted an essay below that has 2 parts: 1) How the government has been starving researchers who hold alternative opinions of funding, and 2) climate cycles show we are starting a cooling period. Readers will recall that David Dilley is a 40-year meteorology veteran and the producer of the [...]

Biofilm matrix composition and localization [Microbiology]

PNAS Early Edition Articles - Wed, 08/26/2015 - 12:04
Biofilm formation is a complex, ordered process. In the opportunistic pathogen Pseudomonas aeruginosa, Psl and Pel exopolysaccharides and extracellular DNA (eDNA) serve as structural components of the biofilm matrix. Despite intensive study, Pel’s chemical structure and spatial localization within mature biofilms remain unknown. Using specialized carbohydrate chemical analyses, we unexpectedly...

Single-molecule FRET studies on neuronal NOS [Biochemistry]

PNAS Early Edition Articles - Wed, 08/26/2015 - 12:04
Mechanisms that regulate the nitric oxide synthase enzymes (NOS) are of interest in biology and medicine. Although NOS catalysis relies on domain motions, and is activated by calmodulin binding, the relationships are unclear. We used single-molecule fluorescence resonance energy transfer (FRET) spectroscopy to elucidate the conformational states distribution and associated...

Intracisternal arrays within the native Golgi [Cell Biology]

PNAS Early Edition Articles - Wed, 08/26/2015 - 12:04
We acquired molecular-resolution structures of the Golgi within its native cellular environment. Vitreous Chlamydomonas cells were thinned by cryo-focused ion beam milling and then visualized by cryo-electron tomography. These tomograms revealed structures within the Golgi cisternae that have not been seen before. Narrow trans-Golgi lumina were spanned by asymmetric membrane-associated...

Commissioning of Ignalina solid waste facilities under way

Cold testing - one of the first stages of the commissioning process - has started at the new Solid Waste Management and Storage Facilities at the shut down Ignalina nuclear power plant in Lithuania.

Canadian accident study puts risks into perspective

World Nuclear News - Wed, 08/26/2015 - 08:05
A Canadian Nuclear Safety Commission study has concluded that there would be no detectable increase in cancer risk for most of the population from radiation released in a hypothetical severe nuclear accident.

Vanity Fair: Global Warming hitting Film Industry Hard – ‘How Extreme Weather Is Melting Hollywood’s Winter Shoots’

Climate Depot - Tue, 08/25/2015 - 20:06
Eric Holthaus, a meteorologist who works for Slate, says climate change may affect Hollywood in several ways: The frequency of extreme weather makes it harder to predict which areas of the world may have snow, rain, or sunny days during any given month. And Hollywood may not be able to rely on “locations that are [...]
