Climatologist Dr. Roy Spencer: ‘Why 2014 Won’t Be the Warmest Year on Record’ – ‘We are arguing over the significance of hundredths of a degree’

Climate Depot - Tue, 10/21/2014 - 13:00
Spencer: ‘The two main research groups tracking global lower-tropospheric temperatures (our UAH group, and the Remote Sensing Systems [RSS] group) show 2014 lagging significantly behind 2010 and especially 1998′: ‘With only 3 months left in the year, there is no realistic way for 2014 to set a record in the satellite data.’  the alarmists will [...]

A long view of nuclear

World Nuclear News - Tue, 10/21/2014 - 10:06
More than a century has passed since radiation and nuclear energy were discovered and the image of those energy sources has undergone much evolution with the passing of several cultural waves, each of which left its mark on the public's perception and attitude to nuclear power, writes Jeremy Gordon.

Tepco boosts water decontamination capacities

World Nuclear News - Tue, 10/21/2014 - 09:31
Testing of a new high-performance water decontamination system has started at the Fukushima Daiichi plant. When in full operation, the new system should increase water treatment capacity while significantly reducing the volume of waste generated.

Licence application for Brazilian mine

World Nuclear News - Tue, 10/21/2014 - 09:19
Mining is expected to begin at Brazil's Engenho uranium deposit next year, according to front-end fuel cycle company Indústrias Nucleares do Brasil. A licence application for the mine is currently before the national regulator.

Parallel gene expression evolution in photophores [Evolution]

PNAS Early Edition Articles - Tue, 10/21/2014 - 09:02
Despite contingency in life’s history, the similarity of evolutionarily convergent traits may represent predictable solutions to common conditions. However, the extent to which overall gene expression levels (transcriptomes) underlying convergent traits are themselves convergent remains largely unexplored. Here, we show strong statistical support for convergent evolutionary origins and massively parallel...

Genomic analyses of A. cinnamomea [Genetics]

PNAS Early Edition Articles - Tue, 10/21/2014 - 09:02
Antrodia cinnamomea, a polyporus mushroom of Taiwan, has long been used as a remedy for cancer, hypertension, and hangover, with an annual market of over $100 million (US) in Taiwan. We obtained a 32.15-Mb genome draft containing 9,254 genes. Genome ontology enrichment and pathway analyses shed light on sexual development...

Evolutionary tradeoffs and eco-evo feedbacks [Ecology]

PNAS Early Edition Articles - Tue, 10/21/2014 - 09:02
Evolution on a time scale similar to ecological dynamics has been increasingly recognized for the last three decades. Selection mediated by ecological interactions can change heritable phenotypic variation (i.e., evolution), and evolution of traits, in turn, can affect ecological interactions. Hence, ecological and evolutionary dynamics can be tightly linked and...

GPR56-G{alpha}12/13 signaling and muscle hypertrophy [Cell Biology]

PNAS Early Edition Articles - Tue, 10/21/2014 - 09:02
Peroxisome proliferator-activated receptor gamma coactivator 1-alpha 4 (PGC-1α4) is a protein isoform derived by alternative splicing of the PGC1α mRNA and has been shown to promote muscle hypertrophy. We show here that G protein-coupled receptor 56 (GPR56) is a transcriptional target of PGC-1α4 and is induced in humans by resistance...

Fangjiashan 1 achieves first criticality

World Nuclear News - Tue, 10/21/2014 - 08:49
Unit 1 of the Fangjiashan plant in China's Zhejiang province has moved closer to commissioning by achieving a sustained chain reaction.

South Africa plans next steps with vendors

World Nuclear News - Tue, 10/21/2014 - 08:36
South Africa is moving towards signing framework agreements with China and Japan and is inviting would-be reactor vendor countries to participate in workshops to showcase their offerings as it moves through the pre-procurement phase of its nuclear new-build plans.

Recent H1N1 strains escape human antibodies [Microbiology]

PNAS Early Edition Articles - Mon, 10/20/2014 - 13:02
Influenza viruses typically cause the most severe disease in children and elderly individuals. However, H1N1 viruses disproportionately affected middle-aged adults during the 2013–2014 influenza season. Although H1N1 viruses recently acquired several mutations in the hemagglutinin (HA) glycoprotein, classic serological tests used by surveillance laboratories indicate that these mutations do not...

Supersymmetric dark matter/LHC [Physics]

PNAS Early Edition Articles - Mon, 10/20/2014 - 13:02
I review the status of the model of dark matter as the neutralino of supersymmetry in the light of constraints on supersymmetry given by the 7- to 8-TeV data from the Large Hadron Collider (LHC).

DAT variant Val559 in transgenic mice [Neuroscience]

PNAS Early Edition Articles - Mon, 10/20/2014 - 13:02
Despite the critical role of the presynaptic dopamine (DA) transporter (DAT, SLC6A3) in DA clearance and psychostimulant responses, evidence that DAT dysfunction supports risk for mental illness is indirect. Recently, we identified a rare, nonsynonymous Slc6a3 variant that produces the DAT substitution Ala559Val in two male siblings who share a...

Ligand for leukocyte tyrosine kinase [Biochemistry]

PNAS Early Edition Articles - Mon, 10/20/2014 - 13:02
There are many transmembrane receptor-like proteins whose ligands have not been identified. A strategy for finding ligands when little is known about their tissue source is to screen each extracellular protein individually expressed in an array format by using a sensitive functional readout. Taking this approach, we have screened a...

Diabetes and allostatic load [Medical Sciences]

PNAS Early Edition Articles - Mon, 10/20/2014 - 13:02
Psychological stress-related processes are thought to contribute to the development and progression of type 2 diabetes, but the biological mechanisms involved are poorly understood. Here, we tested the notion that people with type 2 diabetes experience chronic allostatic load, manifest as dynamic disturbances in reactivity to and recovery from stress...

Peripheral immune system impacts stress response [Neuroscience]

PNAS Early Edition Articles - Mon, 10/20/2014 - 13:02
Depression and anxiety disorders are associated with increased release of peripheral cytokines; however, their functional relevance remains unknown. Using a social stress model in mice, we find preexisting individual differences in the sensitivity of the peripheral immune system that predict and promote vulnerability to social stress. Cytokine profiles were obtained...
