Al writes "Researchers from the University of Connecticut have created a new light-emitting material by doping spun strands of salmon DNA with fluorescent dyes. The material, which is robust because DNA is such a strong polymer, absorbs energy from ultraviolet light and gives off different colors depending on the amounts of dye it contains. A team led by chemistry professor Gregory Sotzing created the new material by mixing salmon DNA with two types of dye, then pumping the solution from a fine needle while a voltage is applied between the needle tip and a grounded copper plate covered with a glass slide. As the liquid jet comes out, it dries and forms long nanofibers that are deposited on the glass slide as a mat. The researchers then spin this nanofiber mat directly on the surface of an ultraviolet LED to make a white-light emitter. The color-tunable DNA material relies on an energy-transfer mechanism between two different fluorescent dyes, and the DNA keeps the dye molecules separated at a distance of 2 to 10 nanometers from each other."

An anonymous reader sent in a video clip showing Sun experimenting with shoving a data center through a simulated 6.7 Earthquake. Everything stays running, but some power cords came out and some screws worked loose. It's still kind of neat to see a bunch of racks shake like a polaroid.

aremstar writes "I'm a final-year Computer Science student from the UK. During my studies, we covered 3 programming languages: C, C++ and Java. The issue is that we didn't cover any of these languages in sufficient depth for me to claim that I have commercial-ready experience. It's one thing being able to write simple programs for class assignments, but those are quite different from writing something as complex as the Linux kernel or a multi-threaded banking app. I'm thinking of spending a few weeks/months studying in order to specialize in one of those languages. Fortran also entered my consideration, as it is great for numerical computing and used by many financial institutions, banks, etc. In terms of skill requirements in job ads, my (brief) experience suggests that most programming jobs require C++, with Java a close second. C — unfortunately — doesn't appear as much. My question is: if you were in my shoes, which language would win your time investment? My heart suggests C, with a little bit of Fortran to complement it, but I'm a bit worried that there might not be enough demand in the job market."

Big Download is running an article with details and screenshots from the MMO under development by NASA. The game makes use of Unreal Engine 3, and it's titled Astronaut: Moon, Mars and Beyond. A demo is planned for later this year, and in 2010 they expect "the first episodic installment of the game" to come out. Jerry Heneghan, founder and CEO of Virtual Heroes, described it thus: "This game is going to be a fresh look at the future circa about 2035. ... The core of the gameplay is going to be people building up their characters and as you move forward, you will have more options unlock with new places to go, new equipment to use and new things to do. We are not so much focused on interstellar flight and all that entails... the gameplay is actually about being in a habitat on a planetary surface and doing things like mining Helium-3 for fuel, operating a hydroponics facility to grow plants and create oxygen and operating robots and vehicles."

Since I've been having serious problems with satellite all week, DeviceGuru's submission was really interesting to me. He says "Inspired by Roku's awesome Netflix video download box and impressed with Boxee's free A/V media center platform, it was merely a matter of time before DeviceGuru blogger Rick Lehrbaum would create the BoxeeBox, an Ubuntu-powered HTPC with Boxee serving as its primary media center UI. Based on a 2.5GHz Core 2 Duo CPU, the BoxeeBox has the look and feel of consumer A/V equipment and packs 2GB RAM, 1TB HDD, CD/DVD drive, USB, Firewire, HDMI, DVI-D, RGB, and 8-channel surround sound audio."
