There is a real irony in the Left’s repeated insinuation that climate realists must be funded, somehow, by the oil industry. In truth, there is plenty of money being distributed to climate scientists, but just about all of it comes from governments, and all government money goes to alarmists who promote government power. From this [...]

‘The large increase in Antarctic sea ice since 2002 is real’

Climate Depot - Tue, 07/22/2014 - 16:04
A new paper is being spun by warmists as debunking the recent record highs in Antarctic sea ice. According to the authors, a change in satellite sensors in December 1991 led to a “significant error” in either the data prior to 12/91 or the data after 12/91, but they don’t know which one.  Color me skeptical, but the alleged step-change [...]

BRICS plans energy association in wake of new bank

World Nuclear News - Tue, 07/22/2014 - 09:33
Russian President Vladimir Putin has announced plans to establish a BRICS "energy association" that will include a fuel reserve bank and an energy policy institute.

Russian waste transport ship completes test mission

The Rossita, a nuclear waste transport ship donated to Russia by Italy in 2011, has completed its first mission.

Genomes of two gut symbionts of eusocial bees [Microbiology]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
Gilliamella apicola and Snodgrassella alvi are dominant members of the honey bee (Apis spp.) and bumble bee (Bombus spp.) gut microbiota. We generated complete genomes of the type strains G. apicola wkB1T and S. alvi wkB2T (isolated from Apis), as well as draft genomes for four other strains from Bombus....

Metaproteomics of coupled biogeochemical cycling [Environmental Sciences]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
Marine oxygen minimum zones (OMZs) are intrinsic water column features arising from respiratory oxygen demand during organic matter degradation in stratified waters. Currently OMZs are expanding due to global climate change with resulting feedback on marine ecosystem function. Here we use metaproteomics to chart spatial and temporal patterns of gene...

Single-cell imaging in the heart [Physiology]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
Knowledge of cardiomyocyte biology is limited by the lack of methods to interrogate single-cell physiology in vivo. Here we show that contracting myocytes can indeed be imaged with optical microscopy at high temporal and spatial resolution in the beating murine heart, allowing visualization of individual sarcomeres and measurement of the...

TLR9 signaling enhances germinal center response [Immunology and Inflammation]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
Recent studies have demonstrated important roles of nucleic acid-sensing Toll-like receptors (TLRs) in promoting protective antibody responses against several viruses. To dissect how recognition of nucleic acids by TLRs enhances germinal center (GC) responses, mice selectively deleted for myeloid differentiation primary-response protein 88 (MyD88) in B cells or dendritic cells...

Regulation of PDL1 and PDL2 expression by DOK3 [Immunology and Inflammation]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
The adaptor Downstream-of-Kinase (DOK) 3 functions as a negative regulator and attenuates B-cell receptor-mediated calcium signaling. Although DOK3 is dispensable for early B-cell development, its role in plasma cell (PC) differentiation is unknown. Here, we show that Dok3−/− mice have increased populations of T follicular-helper (Tfh) and germinal center (GC)...

Plant Golgi UDP-Rha/UDP-Gal transporters [Plant Biology]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
Plant cells are surrounded by a cell wall that plays a key role in plant growth, structural integrity, and defense. The cell wall is a complex and diverse structure that is mainly composed of polysaccharides. The majority of noncellulosic cell wall polysaccharides are produced in the Golgi apparatus from nucleotide...

Helical motion of the cell body enhances motility [Biophysics and Computational Biology]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
We resolve the 3D trajectory and the orientation of individual cells for extended times, using a digital tracking technique combined with 3D reconstructions. We have used this technique to study the motility of the uniflagellated bacterium Caulobacter crescentus and have found that each cell displays two distinct modes of motility,...

Stationary nanoliter droplet array [Engineering]

PNAS Early Edition Articles - Tue, 07/22/2014 - 09:17
Microfluidic water-in-oil droplets that serve as separate, chemically isolated compartments can be applied for single-cell analysis; however, to investigate encapsulated cells effectively over prolonged time periods, an array of droplets must remain stationary on a versatile substrate for optimal cell compatibility. We present here a platform of unique geometry and...

Russia targets 2030 for BN-1200

World Nuclear News - Tue, 07/22/2014 - 09:12
Russia plans to start construction of three BN-1200 sodium-cooled fast neutron reactors before 2030, the director general of Rosenergoatom, Evgeny Romanov, said on 21 July.

Tender for Egyptian plant rescheduled

World Nuclear News - Tue, 07/22/2014 - 09:04
A tender to construct Egypt's first nuclear power plant will now be launched by the end of 2014. The tender for the El-Dabaa plant was originally scheduled for earlier this year.
