The rapidly rising volume of genomic data means that genomic scientists need fast and efficient methods to share, analyze and store sequence information. A major upgrade of Samtools, one of the most popular nextgeneration sequence analysis tools, now supports the highly efficient CRAM format, enabling researcher to easily compress and share their data, reducing costs and facilitating worldwide collaboration.

Many physical systems, from superfluids to pi mesons, are understood to be manifestations of spontaneous symmetry breaking, whereby the symmetries of a system are not realized by its lowest energy state. A consequence of spontaneous symmetry breaking is the existence of excitations known as Goldstone bosons, which account for the broken symmetries. Here the authors investigate systems with larger than usual amounts of broken symmetry.

 'In the analysis of a physical system, the first step is to derive a mathematical model for the system. However, it is important to note that mathematical models, in general, may assume many different forms,' said emeritus professor Chan Wah Chun, 'Depending on the particular system, one mathematical model may be more suitable than others.' ...> Full Article 
 A computer algorithm being developed by Brown University researchers enables users to instantly change the weather, time of day, season, or other features in outdoor photos with simple text commands. Machine learning and a clever database make it possible. A paper describing the work will be presented at SIGGRAPH 2014. ...> Full Article 
Physicists have identified a mechanism that may help explain Zipf's law  a unique pattern of behavior found in disparate systems, including complex biological ones. The journal Physical Review Letters is publishing their mathematical models, which demonstrate how Zipf's law naturally arises when a sufficient number of units react to a hidden variable in a system.

 The happiness of over 18,000 people worldwide has been predicted by a mathematical equation developed by researchers at UCL, with results showing that momenttomoment happiness reflects not just how well things are going, but whether things are going better than expected. ...> Full Article 
 Researchers from the Centre for Genomic Regulation in Barcelona, show that BMP and WNT proteins are the socalled 'Turing molecules' for creating embryonic fingers. Findings explain why polydactyly  the development of extra fingers or toes  is relatively common in humans, affecting up to one in 500 births, and confirms a fundamental theory first proposed by the founding father of computer science, Alan Turing, back in 1952. ...> Full Article

 In a new paper in the Journal of Applied Physics, researchers apply the Construcal Law to airplanes, showing 'that we can witness evolution in our lifetime by documenting the evolution of a flow system that is a little more than a century old: the flying 'humanandmachine species.' ...> Full Article 
String bends, tapping, vibrato and whammy bars are all techniques that add to the distinctiveness of a lead guitarist's sound, whether it's Clapton, Hendrix, or BB King. Now guitarist and physicist Dr. David Robert Grimes has described the physics underlying these techniques in the journal PLOS ONE.

A new study authored by Northwestern Medicine researchers found that reviewing electronic health records using algorithms can successfully identify patients with previously undiagnosed hypertension, or high blood pressure, with a high rate of accuracy. The study, 'A TechnologyBased Quality Innovation to Identify Undiagnosed Hypertension Among Active Primary Care Patients,' was published in the 2014 July/August issue of the Annals of Family Medicine.
