Schrödinger expresses amazement that even with the perturbations caused by heat and environment at the molecular level, the naive physicist’s expectation of wild variability is incorrect, and chemical stability holds. While DNA does sometimes mutate in ways that persist through generations, forming ...
Currently, the influences of grazing on the water and nutrient cycles in alpine meadows, as well as corresponding underlying mechanisms, still remain unclear. The quantitative contributions of influence variables to the nutrient loading variations in rivers and streams in alpine-meadow watersheds need ...
Measurement of the hydrogen isotope ratios of cometary water suggests that some of the Earth's oceans may be derived from comets (Chyba1990; Meier et al.1998). If this is true, comets could also have delivered organics, though the survival of these would depend on the nature of the delive...
As you point out, you are highly qualified and experienced in geology and isotope chemistry. I would expect anything you say about those fields to be correct (within the limits of a blog post) and when I see you discussing them, I will be sure to read, learn and keep quiet. On other...
Although it may be argued that these problems can be overcome with methods such as Stable Isotope Labelling by Amino acids in Cell culture (SILAC) [5], where label incorporation occurs in the cell and therefore allows cellular level normalization, the use of this technique incurs an additional ...
Benzaldehyde is absorbed through the skin and lungs and is then distributed to organs, but it does not accumulate in any specific tissue type. It is rapidly metabolized to benzoic acid, then conjugated with glucuronic acid or glycine, and excreted in the urine. The use pf benzaldehyde as an ...
