This paper describes a possible structure for the paracrystalline form of the sodium salt of deoxyribonucleic acid. The structure consists of two DNA chains wound helically round a common axis, and held together by hydrogen bonds between specific pairs of bases. The assumptions made in deriving the structure are described, and co-ordinates are given for the principal atoms. The structure of the crystalline form is discussed briefly.
A battle that has raged for over a decade between advocates of open science and publishers of traditional scientific journals is coming to a head. Eighty five percent of published papers remain locked behind subscription pay walls, accessible only to those affiliated with universities and other large research institutions. But new journals that make everything they publish freely available are growing rapidly.
We scientists are all so focussed on getting our work published that many of us seem to forget something very important; that publication is just the beginning. After publication is when our manuscripts really have to do their essential work of communicating our science to our peers. If no-one reads the manuscript,
The largest collection of Isaac Newton’s papers has gone digital, committing to open-access posterity the works of one of history’s greatest scientist.Among the works shared online by the Cambridge Digital Library are Newton’s own annotated copy of Principia Mathematica and the ‘Waste Book,’ the notebook in which a young Newton worked out the principles of calculus.
But artificial intelligence, it turns out, is so twentieth century.
The latest buzzword is “augmented intelligence” – the difference being that instead of leaving it up to computers to draw their own conclusions, augmented intelligence uses human analysts as well.
The trend has spawned a new occupation: data scientist. The first summit for data scientists was held in Las Vegas in May and if you’re thinking of retraining, or looking for a new career, you could do a lot worse. A recent report from the McKinsey Global Institute (MGI) forecasts that by 2018 the United States alone could face a shortage of up to 190,000 data scientists and up to 1.5 million data-savvy managers and analysts.
MGI describes “big data” as the next frontier for innovation, competition and productivity, and suggests huge potential savings in sectors such as electronics, finance and insurance, and government.

Prestigious US academic institution Princeton University will prevent researchers from giving the copyright of scholarly articles to journal publishers, except in certain cases where a waiver may be granted.
One of the biggest issues is that the content in these publications is provided to these journals for free, and in many cases, the research that is being produced is publicly funded via government grants. So private corporations are raking in huge sums for access to research they get for nothing — and even the peer-editing of the articles in most journals is done for free by other researchers.
It is easy to understand why. Aiden is a scientist, yes, but while most of his peers stay within a specific field – say, neuroscience or genetics – Aiden crosses them with almost casual abandon. His research has taken him across molecular biology, linguistics, physics, engineering and mathematics. He was the man behind last year’s “culturomics” study, where he looked at the evolution of human culture through the lens of four per cent of all the books ever published. Before that, he solved the three-dimensional structure of the human genome, studied the mathematics of verbs, and invented an insole called the iShoe that can diagnose balance problems in elderly people. “I guess I just view myself as a scientist,” he says.
His approach stands in stark contrast to the standard scientific career: find an area of interest and become increasingly knowledgeable about it. Instead of branching out from a central speciality, Aiden is interested in ‘interdisciplinary’ problems that cross the boundaries of different disciplines. His approach is nomadic. He moves about, searching for ideas that will pique his curiosity, extend his horizons, and hopefully make a big impact. “I don’t view myself as a practitioner of a particular skill or method,” he tells me. “I’m constantly looking at what’s the most interesting problem that I could possibly work on. I really try to figure out what sort of scientist I need to be in order to solve the problem I’m interested in solving.”
