Thank You For Smoking: Cigarette Smokers May Be The Key To Solving Global Warming

Climate Depot - Tue, 05/19/2015 - 12:28
As it turns out, used cigarette butts can be converted into material used for energy storage. South Korean scientists say this material could one day be used to coat the electrodes of supercapacitors which would enhance energy storage for things like electric cars, solar panels and wind turbines. “Our study has shown that used cigarette [...]

BAF-mediated avoidance of autophagy [Cell Biology]

PNAS Early Edition Articles - Tue, 05/19/2015 - 09:07
Knowledge of the mechanisms by which a cell detects exogenous DNA is important for controlling pathogen infection, because most pathogens entail the presence of exogenous DNA in the cytosol, as well as for understanding the cell’s response to artificially transfected DNA. The cellular response to pathogen invasion has been well...

Evolution of IIS/TOR in amniotes [Evolution]

PNAS Early Edition Articles - Tue, 05/19/2015 - 09:07
The insulin/insulin-like signaling and target of rapamycin (IIS/TOR) network regulates lifespan and reproduction, as well as metabolic diseases, cancer, and aging. Despite its vital role in health, comparative analyses of IIS/TOR have been limited to invertebrates and mammals. We conducted an extensive evolutionary analysis of the IIS/TOR network across 66...

Ten-coordinated TiO2 and SiO2 at high pressure [Earth, Atmospheric, and Planetary Sciences]

PNAS Early Edition Articles - Tue, 05/19/2015 - 09:07
We predict by first-principles methods a phase transition in TiO2 at 6.5 Mbar from the Fe2P-type polymorph to a ten-coordinated structure with space group I4/mmm. This is the first report, to our knowledge, of the pressure-induced phase transition to the I4/mmm structure among all dioxide compounds. The I4/mmm structure was...

Structural twists in a viral DNA gatekeeper [Biophysics and Computational Biology]

PNAS Early Edition Articles - Tue, 05/19/2015 - 09:07
Many icosahedral viruses use a specialized portal vertex to control genome encapsidation and release from the viral capsid. In tailed bacteriophages, the portal system is connected to a tail structure that provides the pipeline for genome delivery to the host cell. We report the first, to our knowledge, subnanometer structures...

ASLV vectors dissect multiple neural circuits [Neuroscience]

PNAS Early Edition Articles - Tue, 05/19/2015 - 09:07
Pathway-specific gene delivery is requisite for understanding complex neuronal systems in which neurons that project to different target regions are locally intermingled. However, conventional genetic tools cannot achieve simultaneous, independent gene delivery into multiple target cells with high efficiency and low cross-reactivity. In this study, we systematically screened all receptor–envelope...

Regulation of AMD pathogenesis by factor H [Medical Sciences]

PNAS Early Edition Articles - Tue, 05/19/2015 - 09:07
Complement factor H (CFH) is a major susceptibility gene for age-related macular degeneration (AMD); however, its impact on AMD pathobiology is unresolved. Here, the role of CFH in the development of AMD pathology in vivo was interrogated by analyzing aged Cfh+/− and Cfh−/− mice fed a high-fat, cholesterol-enriched diet. Strikingly,...
