Sodium-based batteries are particularly attractive: Sodium is a cheap, nontoxic, and abundant element that is uniformly distributed around the world and therefore would be ideal as a transport ion for rechargeable batteries.

This paper has two halves. First, I piece together what we know about Margaret Thatcher's training and employment as a scientist. She took science subjects at school; she studied chemistry at Oxford, arriving during World War II and coming under the influence (and comment) of two excellent women scientists, Janet Vaughan and Dorothy Hodgkin. She did a fourth-year dissertation on X-ray crystallography of gramicidin just after the war. She then gathered four years' experience as a working industrial chemist, at British Xylonite Plastics and at Lyons. Second, my argument is that, having lived the life of a working research scientist, she had a quite different view of science from that of any other minister responsible for science. This is crucial in understanding her reaction to the proposals-associated with the Rothschild reforms of the early 1970s-to reinterpret aspects of science policy in market terms. Although she was strongly pressured by bodies such as the Royal Society to reaffirm the established place of science as a different kind of entity-one, at least at core, that was unsuitable to marketization-Thatcher took a different line.

"As the fastest growing energy technology in the world, solar energy continues to account for more and more of the world's energy supply. Currently, most commercial photovoltaic power comes from bulk semiconductor materials. But in the past few years, scientists have been investigating how semiconductor nanostructures can increase the efficiency of solar cells and the newer field of solar fuels. "

Why ask people what they think of a product when you can just scan their brains instead? New Scientist explores the brave new world of neuromarketing

The concept of artificial intelligence clouds our view of the world.

Researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric -- ordinary cotton -- with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.

Scientists have discovered that our brains have the ability to determine the shape of an object simply by processing specially-coded sounds, without any visual or tactile input.

During the past 15 years, the World Wide Web has created remarkable new methods for harnessing the creativity of people in groups, and in the process has created powerful business models that are reshaping our economy. As the Web has undermined old media and software companies, it has demonstrated the enormous power of a new approach, often referred to as Web 2.0. In a nutshell: the secret to the success of bellwethers like Google, Amazon, eBay, Craigslist, Wikipedia, Facebook, and Twitter is that each of these sites, in its own way, has learned to harness the power of its users to add value to-no, more than that, to co-create-its offerings.

WikiLeaks is again publishing a trove of documents, in this case classified U.S. State Department diplomatic cables. The whistle-blower website will gradually be releasing more than 250,000 of these documents in the coming months so that they can be analyzed and gain the attention they deserve. The cables are internal, written communications among U.S. embassies around the world and also to the U.S. State Department. WikiLeaks described the leak as "the largest set of confidential documents ever to be released into the public domain [giving] an unprecedented insight into U.S. government foreign activities."

Our new online intimacies create a world in which it makes sense to speak of a new state of the self, itself. "I am on my cell … online … instant messaging … on the Web"--these phrases suggest a new placement of the subject, wired into society t

...Historians of science have always had a soft spot for the history of theoretical physics. The great theoretical advances of this century -- relativity and quantum mechanics -- have been documented in fascinating historical accounts that have captivated the mind of the cultivated public. There are no comparable studies of the relations between science and engineering. Breaking with the tradition of the Fachidiot, theoretical physicists have bestowed their romantic autobiographies on the world, portraying themselves as the high priests of the reigning cult.

For a period of about a decade, extending from my late undergraduate years to my early postdoctoral years, it would be fair to say that I was obsessed with Ockham's razor. I was convinced that it was the key to understanding how we acquire knowledge about the world. I no longer believe in Ockham's razor.
