EurekaMag.com Publishes New Insights Into Palindrome, Coconut Palm Sugar and Mistral

March 1, 2012

The Life Sciences Magazine EurekaMag.com publishes insights into specific subjects of all areas of natural science. The latest review covers Palindrome which is is a sequence of DNA units that can be read the same way in either direction, Coconut Palm Sugar which is made from the sap of coconut palms and may be sold as coconut sugar, and Mistral which is a strong, cold and usually dry regional wind in France, which accelerates when it passes through the valleys of the Rhone and the Durance Rivers to the coast of the Mediterranean.

The Life and Earth Sciences Magazine EurekaMag.com publishes insights into subjects in all areas of natural sciences including biology, agriculture, horticulture, forestry, geography, environment and health. Drawing from this pool of scientific disciplines, it provides articles, reviews and insights on natural sciences topics. While the Life and Earth Sciences Research Category contains over 36 million references, most of the insights are included in the Life and Earth Sciences Keyword Category of the online magazine. The latter category now includes three newly published insights into Palindrome, Coconut Palm Sugar and Mistral.

The EurekaMag.com insight into Palindrome covers sequences of DNA units that can be read the same way in either direction, with general allowances for adjustments to punctuation and word dividers. The EurekaMag.com insight covers resolution of the junction fragment of DNA which generated two newly synthesized viral telomeres, each of which was covalently associated with NS-1 and contained a duplex copy of the complex palindrome located around the axis of symmetry of the concatemer junction. It also describes the Dyad domain I which consists of the outermost bases on the left arm of the operator palindrome whose alteration causes a shift, but apparently not a major loss, in occupancy by MerR, and no decrease in RNA polymerase occupancy. In contrast, Dyad domain III is tentatively defined by a mutant in the outermost base of the right palindrome arm which is unaffected in either MerR or RNA polymerase occupancy, however, a second lesion within the P-TPCAD -10 hexamer of this mutant limits effective open complex formation. How such giant palindromes are generated remains largely unknown. Recent studies of a palindrome in the ciliate Tetrahymena suggest a novel mechanism that requires chromosome breakage next to short inverted repeats. The prevalence of short inverted repeats in eukaryotic genomes raises the interesting possibility that this process may occur widely as a response to chromosome damage.

EurekaMag.com presents an insight into Coconut Palm Sugar which covers sugar made from the sap of the coconut palm which may be sold as “coconut sugar”. The taste of pure coconut palm sugar resembles that of brown sugar, yet with more rounded caramel and butterscotch notes, without the metallic ending flavor that brown sugar has. The EurekaMag.com review covers an analysis where elution was carried out with acetonitrile/water to which SAM had been added. This enabled separation of eight sugars and glycerol. Analysis of commercial samples of coconut palm sugar showed that they contained only three sugars: sucrose, glucose and fructose. Because of the close interaction of these components, a change in any one of them can alter the whole system. Another analytical study shows that anodic current peaks were indicative of antioxidant activity. The rank order of these sugars was: gula anau > gula merah > China rock honey sugar > soft brown sugar > raw sugar. Gula anau is an unrefined coconut palm sugar, while the other four are from sugarcane. Soft brown sugar and raw sugar are coated brown sugars. The China rock honey sugar contained chrysanthemum flowers, and its antioxidant properties appear to be due to these flowers and not to the sugar per se. Pure white sugar, other rock sugars and rock honey sugars as well as gula Melaka, an unrefined rock sugar from palm trees, had no observable antioxidant activity.

Mistral is a strong, cold and usually dry regional wind in France, coming from the north or northwest, which accelerates when it passes through the valleys of the Rhone and the Durance Rivers to the coast of the Mediterranean around the Camargue region. The Eurekamag.com insight into Mistral includes migration of ladybirds to mountain pastures to find different food sources. During this migration, strong south-western storms often force the ladybirds to shelter in urban habitats. When the sunny weather returns again, due to the mistral, the adults continue the flight in swarms to mountain areas. On Mt. Vettore somre scientists witnessed a “shower” of ladybirds, some of which hid in the turf. When reaching high altitude locations still covered with snow, the adults, exhausted by the long flight, usually remain motionless on the snow. Due to the warming of the sun they sink to a depth of 5-6 cm, so that they remain trapped in the frozen snow during the night. It also covers ecological factors associated with mistral winds, one unprotected and one protected by the mixed hedge from the Mistral wind. The first zone contained a population of psyllids that was significantly larger than that in the protected zone, which harboured a great majority of beneficial insects. This spatial stability over 3 years suggested in particular that climatic factors were related to psyllids, while spatial factors, such as distance from the mixed hedge, were related to beneficial insects.

The Science Magazine EurekaMag.com was launched in November 1998 as the online version of the French science magazine “Eurêka – Le magazine des sciences” published since 1995. During the past decade, it has emerged as a comprehensive aggregator of information on biology, on the applied life sciences agriculture, horticulture and forestry, on the earth sciences, on the environmental sciences, and on the health sciences.
