explosivejared writes: Sheep Marketplace, a.onion marketplace that sprung up in the wake of the Silk Road seizure, closed down over the weekend after nearly 100 thousand BTC, worth around $100 million, were stolen. The market had been plagued by suspicion for weeks, and it all came to a head last week as admins began disallowing withdrawal of bitcoins in escrow. Users revolted. The forum was shutdown. Admins claimed a bug allowed 5,000 BTC to be stolen. Eventually the entire site went down, taking tens of millions of dollars worth BTC with it. It is still unclear who is responsible, but reddit user sheepreloaded2 claims to have identified the wallet containing the stolen bitcoins and has been frustrating attempts to launder them.

There's always a worry that moves like this might turn into mob-led witch hunts, but cooler heads seem to be prevailing. A post warning people of repeating the mistakes made surrounding the accusations of Richard Jewell has been voted to the top of the findbostonbombers reddit. Of particular interest is the subreddit on analysis of the bomb components. Users seem to have established the type of trigger used and may be able to establish a radius that the bomber(s) may have been within during the blast

Now Johnson has replied, and the subsequent debate is online.
With the conversation between Morozov and Johnson as a starting point, I'd like to pose some questions to/.. I think we can all agree that the internet has proven that decentralized organizations can bring significant positive impacts, but what are the limits on this? As Morozov points out, even in ostensibly decentralized organizations there are often hidden hierarchies, and this is true for the Internet as well. Where could the vast, varied phenomenon we call the internet benefit from more openly centralized organization, if it can at all?"
Nanothermal therapy – the use of nanoparticles to cook a tumor to death – is one of the many promising uses of nanotechnology to both improve the effectiveness of cancer therapy and reduce its side effects. Now, a team of investigators from the Texas Center for Cancer Nanomedicine has shown that liver cancer cells will take up targeted gold nanoparticles, absorb radio waves, and generate heat that damages the cells. In addition, the researchers have discovered how to increase the thermal toxicity of these nanoparticles."

Scientific productivity in this sense includes percent of GDP spent on R&D and the overall numbers of researchers, scholarly articles, and patents that a country produces. The article sees this as a natural side effect of the buoying economic prospects of these countries. Perhaps the most positive piece of the story is the fact that a full 35% of scholarly scientific articles in leading journals are now the product of international collaboration. From the article: "[M]ore than 35% of articles in leading journals are now the product of international collaboration. That is up from 25% 15 years ago—something the old regime and the new alike can celebrate.""
