Capturing atmospheric carbon: biological and nonbiological methods

Detection of biological and nonbiological motion.

Often it is claimed that humans are particularly sensitive to biological motion. Here, sensitivity as a detection advantage for biological over nonbiological motion is examined. Previous studies comparing biological motion to nonbiological motion have not used appropriate masks or have not taken into account the underlying form present in biological motion. The studies reported here compare the...

Biological versus nonbiological older brothers and men's sexual orientation.

The most consistent biodemographic correlate of sexual orientation in men is the number of older brothers (fraternal birth order). The mechanism underlying this effect remains unknown. In this article, I provide a direct test pitting prenatal against postnatal (e.g., social/rearing) mechanisms. Four samples of homosexual and heterosexual men (total n = 944), including one sample of men raised i...

Carbon Capturing and Sequestration

Capturing rogue carbon

declare that the warming world is phenomenon beyond all doubt, and that the likelihood of this being caused by the human action of putting greenhouse gases into the atmosphere — and not, say, by increased solar activity, as some have argued — is greater than 90 per cent. For all but the most perverse of sceptics, it ends the basic argument. And it also urgently warns that the risks are greater,...

Halloysite Nanotubes Capturing Isotope Selective Atmospheric CO2

With the aim to capture and subsequent selective trapping of CO2, a nanocomposite has been developed through selective modification of the outer surface of the halloysite nanotubes (HNTs) with an organosilane to make the nanocomposite a novel solid-phase adsorbent to adsorb CO2 from the atmosphere at standard ambient temperature and pressure. The preferential adsorption of three major abundant ...
