Nearly 700 Genetic Factors Found To Influence Human Adult Height 68

damn_registrars writes: A consortium of scientists from many different countries reviewed genome-wide association study data sets of over 250,000 individuals in a search for genetic factors that influence adult height. Looking at Single Nucleotide Polymorphisms, the researchers found 697 distinct genetic markers that can explain some 20 percent of the heritability of human adult height. Previous studies had found around 180 such markers, but the larger sample set increased the ability to detect these changes, both within genes and in non-coding regions. Genes found in this set included ones from pathways not previously connected to skeletal growth.

This study is also significant for the sample size, which allows it to address whether the data from such large sets has a tendency to converge or diverge on genetic pathways; this study particularly favors the latter, which is of great utility toward studying other polygenetic conditions in the future. The original paper is likely paywalled, however the abstract is available for free and some of the collaborators behind it have other bits available for free in the meantime.

An anonymous reader writes "Michael Geist reports that a newly study commissioned by the Government of Canada, which includes some of the most extensive surveying to date of the Canadian population on music purchasing habits, finds what many have long suspected — there is a positive correlation between peer-to-peer downloading and CD purchasing. The Impact of Music Downloads and P2P File-Sharing on the Purchase of Music: A Study For Industry Canada was conducted collaboratively by two professors from the University of London, Industry Canada, and Decima Research, who surveyed over 2,000 Canadians on their music downloading and purchasing habits."

Nanocosmetics Used Since Ancient Egypt 252

Roland Piquepaille writes "French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide (PbS) nanocrystals with a diameter of only 5 nanometers. At a moment where many people wonder if the use of nanoparticles is safe, it's good to know that nanotechnology has been widely used for a very long time."

This is a good time to punt work.
