Catalysis under the graphene cover [Chemistry]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
Graphitic overlayers on metals have commonly been considered as inhibitors for surface reactions due to their chemical inertness and physical blockage of surface active sites. In this work, however, we find that surface reactions, for instance, CO adsorption/desorption and CO oxidation, can take place on Pt(111) surface covered by monolayer...

Role of VEGF-B on peripheral nerve injury [Medical Sciences]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
VEGF-B primarily provides neuroprotection and improves survival in CNS-derived neurons. However, its actions on the peripheral nervous system have been less characterized. We examined whether VEGF-B mediates peripheral nerve repair. We found that VEGF-B induced extensive neurite growth and branching in trigeminal ganglia neurons in a manner that required selective...

Reciprocity triggers children's benevolence [Psychological and Cognitive Sciences]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
A very simple reciprocal activity elicited high degrees of altruism in 1- and 2-y-old children, whereas friendly but nonreciprocal activity yielded little subsequent altruism. In a second study, reciprocity with one adult led 1- and 2-y-olds to provide help to a new person. These results question the current dominant claim...

Queen control of egg fertilization in termites [Evolution]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
Males and females are in conflict over genetic transmission in the evolution of parthenogenesis, because it enhances female reproductive output but deprives the males’ genetic contribution. For males, any trait that coerces females into sexual reproduction should increase their fitness. However, in the termite Reticulitermes speratus, queens produce their replacements...

Neural maintenance of a lost language [Psychological and Cognitive Sciences]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
Optimal periods during early development facilitate the formation of perceptual representations, laying the framework for future learning. A crucial question is whether such early representations are maintained in the brain over time without continued input. Using functional MRI, we show that internationally adopted (IA) children from China, exposed exclusively to...

Charging-free battery powered by low-grade heat [Applied Physical Sciences]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
Efficient and low-cost systems are needed to harvest the tremendous amount of energy stored in low-grade heat sources (<100 °C). Thermally regenerative electrochemical cycle (TREC) is an attractive approach which uses the temperature dependence of electrochemical cell voltage to construct a thermodynamic cycle for direct heat-to-electricity conversion. By varying temperature,...

Cytoplasmic HIV-1 RNA is transported by diffusion [Microbiology]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
Full-length HIV-1 RNA plays a central role in viral replication by serving as the mRNA for essential viral proteins and as the genome packaged into infectious virions. Proper RNA trafficking is required for the functions of RNA and its encoded proteins; however, the mechanism by which HIV-1 RNA is transported...

Earthquake and tsunami forecasts [Earth, Atmospheric, and Planetary Sciences]

PNAS Early Edition Articles - Mon, 11/17/2014 - 14:26
The 5 September 2012 Mw 7.6 earthquake on the Costa Rica subduction plate boundary followed a 62-y interseismic period. High-precision GPS recorded numerous slow slip events (SSEs) in the decade leading up to the earthquake, both up-dip and down-dip of seismic rupture. Deeper SSEs were larger than shallower ones and,...

US funding for supercomputers

World Nuclear News - Mon, 11/17/2014 - 10:42
US energy secretary Ernest Moniz has announced major funding packages to support high performance computing projects - $325 million to build new supercomputers at the US Department of Energy's Oak Ridge and Lawrence Livermore National Laboratories, plus $100 million for R&D into "extreme scale" supercomputing technologies.

Canada ships first synchrotron isotopes

World Nuclear News - Mon, 11/17/2014 - 10:35
The first batch of molybdenum-99 (Mo-99) produced in the Canadian Light Source (CLS) linear accelerator in Saskatoon, Saskatchewan has been shipped in a developmental milestone for the non-reactor production of medical isotopes.

More time to build US MOX plant

World Nuclear News - Mon, 11/17/2014 - 10:07
The construction licence for the partially-built mixed-oxide (MOX) fuel fabrication plant at the Savannah River Site in South Carolina has been extended by ten years at the request of its builder.

U.S.-China deal? ‘A lame duck President, who just suffered a major defeat in the midterm elections has managed the ‘feat’ of getting the Chinese to shake his hand and solemnly promise to keep doing what they are doing for another 16 years’

No uranium processing campaigns are likely to take place in 2015 at the USA's only conventional uranium mill, White Mesa, after the current campaign finishes in March, according to operator Energy Fuels.

Green disinformation on fossil-fuel ‘subsidies’: Report ‘described as ‘subsidies’ normal deductions of expenses and capital costs from revenues for calculation of taxable income’
