MarkWhittington writes "NASA has unveiled a new prototype lunar rover, called the Chariot, a production version of which is hoped to be operational on the lunar surface by 2019. NASA is now testing the Chariot lunar rover in Arizona, on terrain that resembles the lunar surface." Perhaps Arizona's an even closer match to the moon's surface than is Texas, or Moses Lake, WA where NASA was testing the last time we mentioned Chariot. (Here's a bit of video from the Texas round.)

Ars Technica reports on a recent study by Ipsos MediaCT which evaluated gamers with respect to a large variety of social parameters. Among their findings: "55 percent of gamers polled were married, 48 percent have kids, and new gamers — those who have started playing videogames in the past two years — are 32 years old on average." Also, "In terms of hard dollars, the average gaming household income ($79,000) is notably higher than that of nongaming households ($54,000), but the value of the gamer as a marketing target can be seen in a variety of ways. 39 percent of gamers said that friends and family rely upon them to stay up-to-date about the latest technology." The press release for the study is available at IGN.

bshell writes "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 indicates 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."
