Hot Fusion: An Efficient Method to Clone Multiple DNA Fragments as Well as Inverted Repeats without Ligase

31.12.2014 | Changlin Fu et al., PLoS ONE, 2014

by Changlin Fu, William P. Donovan, Olga Shikapwashya-Hasser, Xudong Ye, Robert H. Cole Molecular cloning is utilized in nearly every facet of biological and medical research. We have developed a method, termed Hot Fusion, to efficiently clone one or multiple DNA fragments into plasmid vectors ...

Energies, Vol. 8, Pages 319-337: Hydrogen Storage in Boron Nitride and Carbon Nanomaterials

31.12.2014 | Oku, Takeo, Energies, 2014

Boron nitride (BN) nanomaterials were synthesized from LaB6 and Pd/boron powder, and the hydrogen storage was investigated by differential thermogravimetric analysis, which showed possibility of hydrogen storage of 1–3 wt%. The hydrogen gas storage in BN and carbon (C) clusters was also ...

Maternal temperature history activates Flowering Locus T in fruits to control progeny dormancy according to time of year [Plant Biology]

30.12.2014 | Min Chen; Dana R. MacGregor; Anuja Dave; Hannah Florance; Karen Moore; Konrad Paszkiewicz; Nicholas Smirnoff; Ian A. ..., Proceedings of the National Academy of Sciences current issue, 2014

Seasonal behavior is important for fitness in temperate environments but it is unclear how progeny gain their initial seasonal entrainment. Plants use temperature signals to measure time of year, and changes to life histories are therefore an important consequence of climate change. Here we show ...

Reply to Abatzoglou et al.: Atmospheric controls on northwest United States air temperatures, 1948-2012 [Physical Sciences]

30.12.2014 | James A. Johnstone; Nathan J. Mantua, Proceedings of the National Academy of Sciences current issue, 2014

We recently documented a strong relationship between northeast Pacific sea-level pressure (SLP) and coastal North American sea surface temperature (SSTs) and surface air temperatures (SATs), concluding that atmospheric circulation changes produced nearly all observed coastal warming from 1900 to ...

Electronic evidence of an insulator-superconductor crossover in single-layer FeSe/SrTiO3 films [Physics]

30.12.2014 | Junfeng He; Xu Liu; Wenhao Zhang; Lin Zhao; Defa Liu; Shaolong He; Daixiang Mou; Fangsen Li; Chenjia Tang; Zhi Li; L ..., Proceedings of the National Academy of Sciences current issue, 2014

In high-temperature cuprate superconductors, it is now generally agreed that superconductivity is realized by doping an antiferromagnetic Mott (charge transfer) insulator. The doping-induced insulator-to-superconductor transition has been widely observed in cuprates, which provides important ...

Questionable evidence of natural warming of the northwestern United States [Physical Sciences]

30.12.2014 | John T. Abatzoglou; David E. Rupp; Philip W. Mote, Proceedings of the National Academy of Sciences current issue, 2014

Johnstone and Mantua (1) claim that changes in atmospheric circulation were the primary cause of the observed warming of sea surface temperature around the northeastern Pacific margins and surface air temperature (SAT) in Northern California, Oregon, and Washington from 1901 to 2012. The results ...

Emergence of superconductivity in heavy-electron materials [Physics]

23.12.2014 | Yi-feng Yang; David Pines, Proceedings of the National Academy of Sciences current issue, 2014

Although the pairing glue for the attractive quasiparticle interaction responsible for unconventional superconductivity in heavy-electron materials has been identified as the spin fluctuations that arise from their proximity to a magnetic quantum critical point, there has been no model to ...

Energies, Vol. 7, Pages 8465-8482: Computational Fluid Dynamic Modeling of Horizontal Air-Ground Heat Exchangers (HAGHE) for HVAC Systems

22.12.2014 | Congedo, Paolo Maria; Lorusso, Caterina ; De Giorgi, Maria Grazia; Laforgia, Domenico, Energies, 2014

In order to satisfy the requirements of Directive 2010/31/EU for Zero Energy Buildings (ZEB), innovative solutions were investigated for building HVAC systems. Horizontal air-ground heat exchangers (HAGHE) offer a significant contribution in reducing energy consumption for ventilation, using the ...

[Technical Response] Response to Comment on “A 12-million-year temperature history of the tropical Pacific Ocean”

19.12.2014 | Yi Ge Zhang; Mark Pagani; Zhonghui Liu, Science , 2014

Contrary to our conclusions, Ravelo et al. argue that our TEX86-based sea surface temperature (SST) records do not conflict with the supposition of “permanent El Niño–like” conditions during the early Pliocene. We show that the way Ravelo et al. treat the existing temperature data perpetuates an ...

[Report] One-pot room-temperature conversion of cyclohexane to adipic acid by ozone and UV light

19.12.2014 | Kuo Chu Hwang; Arunachalam Sagadevan, Science , 2014

A photochemical route to a nylon precursor could prove more environmentally benign than current approaches. Authors: Kuo Chu Hwang, Arunachalam Sagadevan
