Isolated populations are genetically less diverse but linguistically more diverse. A new PNAS study documents an inverse global correlation between genetic and structural linguistic diversity, and the signal is stronger than climate or terrain. #linguistics #populationgenetics #languagediversity https://www.anthropology.net/p/where-languages-diverge-most-genomes

“Juggling is sometimes called the art of controlling patterns, controlling patterns in time and space”*…

A skill for our times…

The Library of Juggling is an attempt to list all of the popular (and perhaps not so popular) juggling tricks in one organized place. Despite the growing popularity of juggling, few websites are dedicated to collecting and archiving the various patterns that are being performed. Most jugglers are familiar with iconic tricks such as the Cascade and Shower, but what about Romeo’s Revenge or the 531 Mills Mess? The goal of this website is to guarantee that the tricks currently circulating around the internet and at juggling conventions are found, animated, and catalogued for the world to see. It is a daunting task, but for the sake of jugglers everywhere it must be done.

For every trick found in the Library, there will be an animated representation of the pattern created via JugglingLab, in addition to general information about the trick (siteswap, difficulty level, prerequisite tricks, etc.). If I am able to run the pattern, then I will provide a text-based tutorial for the trick with the help of animations. I will also include links to other tutorials for the trick that can be found online, ranging from YouTube videos to private sites like this one. If I am unable to provide my own tutorial, there will still be a short description of the trick in addition to outside tutorials and demonstrations…

… if you have come to the Library looking to find out how to start juggling, than it would be best to begin with the Three Ball Cascade pattern. If you are a juggler who is already familiar with the basics, then the various tricks included in the Library can be accessed via the navigation tree on the left, or you can click here to view all of the tricks by difficulty…

Enjoy “The Library of Juggling.”

And see also: “The Museum of Juggling History,” the resources at the International Jugglers’ Association, and “The world cannot be governed without juggling.”

* mathematician (and juggler) Ronald Graham

As we toss ’em up, we might send carefully-calculated birthday greetings to G. H. Hardy; he was born on this date in 1877. A mathematician who made fundamental contributions to number theory and mathematical analysis, Hardy juggled other interests as well– for example his  Hardy–Weinberg principle (“allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences”) is now a basic principle of population genetics.

In Hardy’s own estimation, his greatest contribution was something else altogether: from 1917, Hardy was the mentor of the Indian mathematician Srinivasa Ramanujan, a relationship that has become celebrated.  Hardy almost immediately recognised Ramanujan’s extraordinary (albeit untutored brilliance), and the two became close collaborators. When asked by a young Paul Erdős what his greatest contribution to mathematics was, Hardy unhesitatingly replied that it was the discovery of Ramanujan, remarking that on a scale of mathematical ability, his own ability would be 25, Littlewood would be 30, Hilbert would be 80, and Ramanujan would be 100.

Variome (Evolutionary biology 🧬)

The variome is the whole set of genetic variations found in populations of species that have gone through a relatively short evolution change. For example, among humans, about 1 in every 1,200 nucleotide bases differ. The size of human variome in terms of effective population size is claimed to be about 10,000 individuals. This variation rate is comparatively small ...

(1/2) Very happy to announce the publication of our latest work by my former student Sylvain Pouzet in @journal-evo.bsky.social: "Gene network topology drives the mutational landscape of gene expression". Based on simulations, we show that the size and pleiotropy of mutations affecting gene expression heavily depend on the structure of the underlying gene network.

This newly-recognized butterfly species is endemic to a single alluvial fan in Waterton Lakes National Park, Alberta, Canada. This adds to a significant list of isolated species occurrences in and near this small park, including 7 relict freshwater species in upper Waterton Lake, brachypterous lake-dwelling stoneflies, and if memory serves, several plant species. A Wisconsinan ice-free refugium here or nearby?

Intriguing: modeling and empirical data support that after whole genome duplication (autotetraploids) genetic variation rises, and mutation load increases because deleterious mutations are masked by additional chromosome copies

Wolf distribution (Biogeography 🌍)

Wolf distribution is the species distribution of the wolf. Originally, wolves occurred in Eurasia above the 12th parallel north and in North America above the 15th parallel north. However, deliberate human persecution has reduced the species' range to about one-third, because of livestock predation and fear of wol...

This observation suggests that the main patrilineal expansion in China occurred in the Neolithic Era and might be related to the development of agriculture.” #isogg #dna #populationgenetics #chinese

We investigated the effect of a fishway on the genetic structure of brown trout populations, finding that the fishway *increased* genetic structuring, we think because it enabled fish to move to their preferred spawning sites.
