Omomyid was among several readers writing in about the production of microscopic amounts of ultra-dense deuterium by scientists at the University of Gothenberg, in Sweden. A cubic centimeter of the stuff would weigh 287 lbs. (130 kg). UDD is 100,000 times more dense than water, and a million times more dense than deuterium ice, which is a common fuel in laser-ignited fusion projects. The researchers say that, if (big if) the material can be produced in large quantities, it would vastly improve the chances of starting a fusion reaction, as the atoms are much closer together. Such a D-D fusion reaction would be cleaner than one involving highly radioactive tritium. Many outlets have picked up the same press release that Science Daily printed pretty much verbatim (as is their wont); there doesn't seem to be much else about this on the Web. Here's the home page of one of the researchers. The press release gives no hint as to how the UDD was produced. Reader wisebabo asks: "I can easily imagine a material being compressed by some heavy duty diamond anvil to reach this density, the question is: what happens when you let the pressure off? Will it expand (explosively one would presume) back to its original volume?"

Philipp Lenssen writes "Google announced their very own browser project called Google Chrome — an announcement in the form of a comic book drawn by Scott McCloud, no less. Google says Google Chrome will be open source, include a new JavaScript virtual machine, include the Google Gears add-on by default, and put the tabs above the address bar (not below), among other things. I've also uploaded Google's comic book with all the details (details given from Google's perspective, anyway... let's see how this holds up). While Google provided the URL www.google.com/chrome there's nothing up there yet."

An anonymous reader commends a recently published study involving a new way to analyze genetic variation in human populations (full article published in PLOS Genetics): "[S]cientists from Ireland, the UK and the US analysed 2,540 genetic markers in the DNA of almost 1,000 people from around the world whose genetic material had been collected by the Human Genome Diversity Project. The results include a number of surprises... the Yakut people of northern Siberia were found to have received a significant genetic contribution from the population of the Orkney Islands, which lie off the coast of Scotland... there must have been a period of gene flow from northern Europe to east Asia. The study also shed light on the peopling of the Americas, as the results suggest that the native populations of north and south America have different origins."

OMNIpotusCOM writes "Tickets to the Olympic opening and closing ceremonies will contain a microchip with information about the ticket holder, including a photograph, passport details, addresses, e-mail, and telephone numbers. The stated intent is to keep troublemakers out of the 91,000-seat National Stadium so that they cannot cause disruptions while China is on world-wide television, but it brings up serious concerns for privacy and identity theft."

NewYorkCountryLawyer writes "As we say in the legal profession, 'issue has been joined' in Viacom v. YouTube. In its answer to Viacom's complaint (PDF), filed Friday, YouTube says Viacom's lawsuit is intended to 'challenge... the protections of the Digital Millennium Copyright Act ("DMCA") that Congress enacted a decade ago to encourage the development of services like YouTube.' It goes on to say that the suit 'threatens the way hundreds of millions of people legitimately exchange information, news, entertainment, and political and artistic expression.'"

coondoggie writes "Until today, most Internet-based real-estate brokers were considered second-class citizens, and their clients were left in the cold. But perhaps that will change with today's news that the Department of Justice has reached a proposed settlement with the National Association of Realtors that requires NAR to let Internet-based residential real estate brokers compete with traditional brokers. NAR has agreed to be bound by a 10-year settlement, under whose terms NAR will repeal its anticompetitive policies and require affiliated multiple listing services to repeal their rules that were based on these policies." Here's the whole settlement document on the DoJ's site.
