‘The Climate Crisis & Renewable Energy Industry has become a $1.5-trillion-a-year business’

Climate Depot - Sat, 08/22/2015 - 07:28
According to a 200-page analysis by the Climate Change Business Journal, this Climate Industrial Complex can be divided into nine segments: low carbon and renewable power; carbon capture and storage; energy storage, like batteries; energy efficiency; green buildings; transportation; carbon trading; climate change adaptation; and consulting and research. Consulting alone is a $27-billion-per-year industry that [...]

CD38 depletes NADP causing endothelial dysfunction [Medical Sciences]

PNAS Early Edition Articles - Fri, 08/21/2015 - 13:14
In the postischemic heart, coronary vasodilation is impaired due to loss of endothelial nitric oxide synthase (eNOS) function. Although the eNOS cofactor tetrahydrobiopterin (BH4) is depleted, its repletion only partially restores eNOS-mediated coronary vasodilation, indicating that other critical factors trigger endothelial dysfunction. Therefore, studies were performed to characterize the unidentified...

Protein folding and disulfide bonds [Chemistry]

PNAS Early Edition Articles - Fri, 08/21/2015 - 13:14
The Anfinsen principle that the protein sequence uniquely determines its structure is based on experiments on oxidative refolding of a protein with disulfide bonds. The problem of how protein folding drives disulfide bond formation is poorly understood. Here, we have solved this long-standing problem by creating a general method for...

Disposal beats MOX in US comparison

World Nuclear News - Fri, 08/21/2015 - 09:58
America is reconsidering how it will dispose of 34 tonnes of plutonium as the previous plan involving a MOX plant has been said to be twice as costly as a dilution and disposal option in a leaked Department of Energy report.

Pakistan breaks ground for new Karachi units

World Nuclear News - Fri, 08/21/2015 - 09:36
Pakistani prime minister Nawaz Sharif yesterday held a ceremony to mark the start of construction of two Chinese-designed Hualong One units near the coastal city of Karachi.

Russia tests fuel assemblies for BN-800 fast reactor

World Nuclear News - Fri, 08/21/2015 - 06:24
Russia's Mining and Chemical Combine said today that its mixed-oxide fuel fabrication facility has completed tests on putting together the first nuclear fuel assemblies for the BN-800 fast neutron reactor. The BN-800 is unit 4 at the Beloyarsk nuclear power plant in the Sverdlovsk district.

Hottest July in 4000 years? Not even the hottest July since *2014* according to satellites

Hottest July in 4000 years? Not even the hottest July since *2014* according to satellites http://joannenova.com.au/2015/08/hottest-july-in-4000-years-not-even-the-hottest-july-since-2014-according-to-satellites/ NOAA has a press release out being picked up around the world. For example, the DailyMail, UK, is saying July was the hottest month since records began in 1880 as heatwaves swept the Earth’s countries and oceans. Other silly [...]

Climatologist Dr. John Christy: We Have a ‘Moral Imperative’ to Burn Fossil Fuels – ‘The global climate is not very sensitive to CO2′

Climate Depot - Thu, 08/20/2015 - 20:54
The pope’s encyclical “displays a lack of understanding of how the real world works,” Christy told CNSNews.com. According to microwave data from satellites going back to 1978, which are precise to within .08 of a degree, “very little warming is taking place,” he pointed out. … Carbon-based energy, which is “the most affordable and reliable [...]

Snapping transitions in creased shells [Applied Physical Sciences]

PNAS Early Edition Articles - Thu, 08/20/2015 - 13:51
Curvature and mechanics are intimately connected for thin materials, and this coupling between geometry and physical properties is readily seen in folded structures from intestinal villi and pollen grains to wrinkled membranes and programmable metamaterials. While the well-known rules and mechanisms behind folding a flat surface have been used to...

Haploidization by a CENH3 point mutation [Agricultural Sciences]

PNAS Early Edition Articles - Thu, 08/20/2015 - 13:51
The chromosomal position of the centromere-specific histone H3 variant CENH3 (also called “CENP-A”) is the assembly site for the kinetochore complex of active centromeres. Any error in transcription, translation, modification, or incorporation can affect the ability to assemble intact CENH3 chromatin and can cause centromere inactivation [Allshire RC, Karpen GH...

Social dynamics and ecological regime shifts [Sustainability Science]

PNAS Early Edition Articles - Thu, 08/20/2015 - 13:51
Regime shifts triggered by human activities and environmental changes have led to significant ecological and socioeconomic consequences in marine and terrestrial ecosystems worldwide. Ecological processes and feedbacks associated with regime shifts have received considerable attention, but human individual and collective behavior is rarely treated as an integrated component of such...

What limits the speed of muscle contraction? [Biochemistry]

PNAS Early Edition Articles - Thu, 08/20/2015 - 13:51
It is not known which kinetic step in the acto-myosin ATPase cycle limits contraction speed in unloaded muscles (V0). Huxley’s 1957 model [Huxley AF (1957) Prog Biophys Biophys Chem 7:255–318] predicts that V0 is limited by the rate that myosin detaches from actin. However, this does not explain why, as...

Weather data at Washington’s Reagan National Airport fiddled

Climate Depot - Thu, 08/20/2015 - 12:44
Are political considerations superseding scientific ones at the National Oceanic and Atmospheric Administration? When confronted with an obviously broken weather station that was reading way too hot, they replaced the faulty sensor — but refused to adjust the bad readings it had already taken. And when dealing with “the pause” in global surface temperatures that [...]

Warmist Joe Romm: ‘Why President Trump Would Likely Honor A Paris Climate Deal & EPA’s’ Climate Regs

Climate Depot - Thu, 08/20/2015 - 11:02
First, the Paris accord is almost certain to be a very good deal for us (as I discussed here), and Trump sees himself as a great deal-maker above all else. Second, Trump understands the value of “brand” — and nothing would ruin his brand (or this country’s) more permanently than to be the guy (or [...]
