Olu Dara Jones (born Charles Jones III; January 12, 1941) is an American cornetist, guitarist and singer. He is the father of rapper Nas.
Olu Dara was born Charles Jones in Natchez, Mississippi, United States, the son of Ella Mae and Charles (Rufus) Jones.
Nas grandfather, Charles Jones II, was a singer touring with a quartet when Olu Dara was born, and everyone in his family was raised playing instruments.

Interestingly they have a lot of background on Nas' maternal ancestry but little on his paternal line.

Haplogroup I1-M253 (M253, M307, P30, P40) displays a very clear frequency gradient, with a peak frequency of approximately 35% among the populations of southern Norway, southwestern Sweden, and Denmark, and rapidly decreasing frequencies toward the edges of the historically Germanic-influenced world. A notable exception is Finland, where frequency in West Finns is up to 40%, and in certain provinces like Satakunta more than 50%.

Gene name errors are widespread in the scientific literature


The spreadsheet software Microsoft Excel, when used with default settings, is known to convert gene names to dates and floating-point numbers. A programmatic scan of leading genomics journals reveals that approximately one-fifth of papers with supplementary Excel gene lists contain erroneous gene name conversions.

Validating TrueAllele® DNA Mixture Interpretation


Abstract:  DNA mixtures with two or more contributors are a prevalent form of biological evidence. Mixture interpretation is complicated by the possibility of different genotype combinations that can explain the short tandem repeat (STR) data. Current human review simplifies this interpretation by applying thresholds to qualitatively treat STR data peaks as all-or-none events and assigning allele pairs equal likelihood. Computer review, however, can work instead with all the quantitative data to preserve more identification information. The present study examined the extent to which quantitative computer interpretation could elicit more identification information than human review from the same adjudicated two-person mixture data. The base 10 logarithm of a DNA match statistic is a standard information measure that permits such a comparison. On eight mixtures having two unknown contributors, we found that quantitative computer interpretation gave an average information increase of 6.24 log units (min = 2.32, max = 10.49) over qualitative human review. On eight other mixtures with a known victim reference and one unknown contributor, quantitative interpretation averaged a 4.67 log factor increase (min = 1.00, max = 11.31) over qualitative review. This study provides a general treatment of DNA interpretation methods (including mixtures) that encompasses both quantitative and qualitative review. Validation methods are introduced that can assess the efficacy and reproducibility of any DNA interpretation method. An in-depth case example highlights 10 reasons (at 10 different loci) why quantitative probability modeling preserves more identification information than qualitative threshold methods. The results validate TrueAllele® DNA mixture interpretation and establish a significant information improvement over human review.

The problem addressed in this paper is to define a learning algorithm for the prediction of splice site locations in human DNA in the presence of sequence annotation errors in the training data. To this aim we generalize a previous machine learning algorithm. Experimental results on a common dataset including errors show the algorithm outperforms its previous version, in particular in the complexity of the produced hypothesis.

Volkswagen under investigation over illegal software that masks emissions


The US government has ordered Volkswagen to recall almost 500,000 cars after discovering that the company deployed sophisticated software to cheat emission tests allowing its cars to produce up to 40 times more pollution than allowed.
