So far all lifeforms on Earth have a phosphorous based chemistry, in particular as the backbone of DNA. In 2010 a paper was published in science claiming that arsenic based bacteria were living in a California lake. That paper was finally retracted by the journal Science the other day.

Some of the world’s largest record labels, including Sony and Universal Music Group, filed a lawsuit against the Internet Archive and others for the Great 78 Project (https://great78.archive.org), a community effort for the preservation, research and discovery of 78 rpm records that are 70 to 120 years old. The project has been in operation since 2006 to bring free public access to a largely forgotten but culturally important medium. Through the efforts of dedicated librarians, archivists and sound engineers, we have preserved hundreds of thousands of recordings that are stored on shellac resin, an obsolete and brittle medium. The resulting preserved recordings retain the scratch and pop sounds that are present in the analog artifacts; noise that modern remastering techniques remove.

The Verge has a great photo-essay about Tûranor PlanetSolar, the first boat to circle the globe with solar power. The boat is currently in NYC. Among other remarkable facts, the captain (Gérard d'Aboville) is one of those rare individuals who solo-rowed across both the Atlantic and Pacific Oceans, journeys that took 71 and 134 days, respectively. The piece has a lot of detail about control systems and design.

According to the CBC, there was a massive leak of "files containing information on over 120,000 offshore entities — including shell corporations and legal structures known as trusts — involving people in over 170 countries. The leak amounts to 260 gigabytes of data, or 162 times larger than the U.S. State Department cables published by WikiLeaks in 2010...In many cases, the leaked documents expose insider details of how agents would incorporate companies in Caribbean and South Pacific micro-states on behalf of wealthy clients, then assign front people called "nominees" to serve, on paper, as directors and shareholders for the corporations — disguising the companies' true owners." Makes a good read and there are some good interactive components. Perhaps slashdot readers can figure out how the source of the leak, the D.C.-based International Consortium of Investigative Journalists got their hands on this data.

With Christmas around the corner I know we are all thinking about religion, or at least maybe wondering why this one religion dominates the rest for these few weeks. A fellow named Rodrigo Braz Monteiro (amz) posted this list comparing each programming language to a religion. Guaranteed to make you chuckle and generate a good long thread here on slashdot. Great way to pass the time as work winds down this week and we relate to our own programming faiths during this very special time of year. Merry PHPmas.

An article in science blog says we may have to rethink how genes work. So called "junk DNA" actually appears to be functional. What's more it works in a mysterious way involving multiple overlaps that seems to be connected in some sort of network. From the article:
The ENCODE consortium's major findings include the discovery that the majority of DNA in the human genome is transcribed into functional molecules, called RNA, and that these transcripts extensively overlap one another. This broad pattern of transcription challenges the long-standing view that the human genome consists of a relatively small set of discrete genes, along with a vast amount of so-called junk DNA that is not biologically active.
The new data indicate the genome contains very little unused sequences and, in fact, is a complex, interwoven network. In this network, genes are just one of many types of DNA sequences that have a functional impact. "Our perspective of transcription and genes may have to evolve," the researchers state in their Nature paper, noting the network model of the genome "poses some interesting mechanistic questions" that have yet to be answered.
