Interesting discussion of how to tell apart classical and quantum systems using Bells inequality. The basic idea is finding more correlated events between two separate
systems than one might expect classically were they are decoupled. This implies that there is a quantum characteristic to the system. This fact can be exploited to measure the degree to which two systems are behaving as a “quantum unit” in relation to cryptographic applications and large-scale quantum
computation.

Great link on True Cost of Science #Publishing: $5K/article with #openaccess giving clearer view on costs
http://www.nature.com/news/open-access-the-true-cost-of-science-publishing-1.12676 MT @Richvn

Interesting discussion on the cost of scientific publishing. It appears that the open access model, in addition to having free access to the content, is also giving people a much more open view of the cost. This is because most of the costs are upfront and clear to see author paid charges as opposed to being hidden in secret contracts to libraries. A number of the journals have a cost of
~$5000/article going down to as low as ~$1300 for PLoS ONE.
It is claimed that some of the marquee subscription
publishers such as Nature have costs of >$30,000/article
and it is interesting thinking about how to meld these
together.

Nature: A gene of rare effect. Interesting discussion of #PCSK9 as a poster child for #LOF mutations
http://www.nature.com/news/genetics-a-gene-of-rare-effect-1.12773 #genetics

The woman who had this LOF mutation was identified in the large Dallas cholesterol study based on her family history.

QT:”
How did the gene exert such profound effects on LDL cholesterol levels? As researchers went on to determine, the PCSK9 protein normally circulates in the bloodstream and binds to the LDL receptor, a protein on the surface of liver cells that captures LDL cholesterol and removes it from the blood. After binding with the receptor, PCSK9 escorts it into the interior of the cell, where it is eventually degraded. When there is a lot of PCSK9 (as in the French families), there are fewer LDL receptors remaining to trap and remove bad cholesterol from the blood. When there is little or no PCSK9 (as in the black people with mutations), there are more free LDL receptors, which in turn remove more LDL cholesterol.
