Starwatch: northern autumn brings the loneliest star

The blue-white star Fomalhaut, one of the brightest in the sky, can be seen low in the southern sky from the northern hemisphereIf there is one star that signposts autumn in the northern hemisphere, it ’sFomalhaut. Now is a good time to start your search for this bluish-white star. The chart shows the view at midnight (BST) as 23 September becomes the 24th, looking south. With a clear horizon, Fomalhaut will appear low and isolated as there are no other stars of comparable brightness around it. This has led astronomers to nickname it “the loneliest star”. The star itself is about twice the size and mass of the sun, yet pumps out about 16 times more light than our star. At a distance of 25 light years, it is a relatively nearby star. It is the brightest star in the faint southern constellation ofPiscis Austrinus. While it is relatively easy to see, the other stars in this constellation are difficult to pick out from northern latitudes because they are so faint and appear so low in the sky. The star ’s name is Arabic and translates literally as “mouth of the whale”.Continue reading...

Publication date: Available online 16 November 2019Source: Journal of Health EconomicsAuthor(s): Dimitris Christelis, Dimitris Georgarakos, Anna Sanz-de-GaldeanoAbstractEconomic theory predicts that a reduction in background risk should induce financial risk-taking, particularly for individuals with low stock market participation costs. Hence, health insurance coverage could affect financial risk-taking by offsetting health-related background risk. We use a regression discontinuity design to examine whether Medicare eligibility at age 65 increases stockholding in the US and find that it does so for those with college educa...

In this study, serum IL6 was measured by ELISA, and the HSD11B1rs12086634(T/G) polymorphism was analyzed using a TaqMan allelic discrimination assay technique. There were statistically significant differences between the two studied groups concerning the serum IL-6 level and HSD11B1rs12086634(T/G) genotype distribution, with increased serum IL6 and increased frequencies of the GG and TG genotypes in patients with PCO. The GG genotype of HSD11B1 rs12086634(T/G) and its associated high level of serum IL-6 may represent genetic risk factors for PCOS.

ConclusionThe CFQL-2 is a brief, reliable scale that effectively measures psychosocial aspects of QoL and is sensitive to changes in QoL in families of children with ASD or related neurodevelopmental disorders. Child externalizing behavior is strongly associated with reductions in multiple aspects of child and family psychosocial QoL.
