Hydrogen metabolism: A eukaryote taps into the electron sink.

The ability to harvest reducing power from molecular hydrogen was once considered a prokaryotic trait. New research challenges this notion by finding the first eukaryotic organism capable of oxidizing hydrogen.

Comparison of Oil Content and Fatty Acids Profile of Western Schley, Wichita, and Native Pecan Nuts Cultured in Chihuahua, Mexico.

Two different extraction processes, Soxhlet and ultrasound, were used to obtain the oil extracts of Western Schley, Wichita, and Native pecan nuts cultured in Chihuahua, Mexico. The aspects evaluated in this study were the extraction yield of the processes and fatty acids' profile of the resulting extracts. Gas chromatography coupled with mass spectrometry (GC-MS) was used to identify and determine the composition percentage of fatty acids present in pecan nuts oils extracted.
