Pinching out sulfur

Article Abstract:

Removing sulfur from crude oil needs new, innovative technology with better selectivity upstream, less need for energy and capital-intensive separation processing downstream is focused. One of the sulfur stripping technique is developed by SulfCo to refine heavy oils into sweet crude called acoustic cavitation and other technique designed by Trans Ionics that would make desulfurization more efficient and with less capital investment there by proving an elegant solution to the problem.

Leafy letdown

Article Abstract:

Large, long-term studies have mostly failed to corroborate initial signs of cancer-fighting powers of produce despite the belief that eating fruits and vegetables will reduce the risk of chronic ills such as heart diseases, high blood pressure and cancer. However, even with the uncertainty, the National Cancer Institute's recommendation of having five-to-nine servings of fruits and vegetables daily could be part of overall healthy eating habits and block the disease's early stages.

RNA to the rescue: Novel inheritance patterns violet Mendel's laws

Article Abstract:

Biologists believe that RNA is a special molecule with more versatility, as in various organisms the genetic information is inherited in the form of DNA, copied into RNA and expressed as protein. The non-mendelian method of inheritance discovered in Arabidopsis plants may be just one example of RNA's ability to introduce variety absent from an organism's DNA.
