The International Earth Rotation and Reference Systems Service has announced that a leap second will be added on December 31, 2008 at 23h 59m 60s, meaning that this year will be exactly one second longer. The last leap second occurred Dec 31, 2005; they are added due to fluctuations in the rotational speed of the earth. You can read all about leap seconds on Wikipedia."

beuges writes "Microsoft has announced over the weekend that it would allow computer manufacturers to receive copies of XP until the end of May 2009, shortly before Windows 7 is expected to hit the market. This should allow users to skip Vista entirely and move straight to 7, which has been receiving cautiously favorable reviews of pre-release and leaked alphas."

MediaSight writes "Shortfin mako sharks can shoot through the ocean at up to 50 miles per hour (80 kilometres an hour). Now a trick that helps them to reach such speeds has been discovered — the sharks can raise their scales to create tiny wells across the surface of their skin, reducing drag like the dimples on a golf ball."

zootropole writes "If you are using Firefox 3 (or even Chrome) you should consider taking a look at Mozilla's Minefield. This browser (alpha version yet, but stable) would give a new meaning to 'fast browsing experience.' Some Firefox extensions aren't supported, but riding the fastest javascript engine on the planet definitely worth a try. Minefield's install won't affect your Firefox, so there's no risk trying it. It's fast. Really. And I'm loving it." Reviews popping up around the web are overwhelmingly positive, calling the upcoming browser crazy fast, blisteringly fast, etc.

Iddo Genuth writes to tell us that Samsung and Unidym have shown the world's first carbon nanotube-based color e-paper. Interestingly, the new film is electrically conductive while remaining almost completely translucent and only 50 nanometers thick. "The company also mentions that the EPD [electrophoretic displays] has important advantages over conventional flat panel displays. EPDs have very low power consumption and bright light readability, which means that even under bright lights or sunlight, the user would be able to view the display clearly. Furthermore, since the device uses the thin CNT films, applications can include e-paper and displays with thin, flexible substrates. Power consumption is lowered due to the EPD's ability to reflect light and therefore able to preserve text or images on the display without frequently refreshing."

snydeq writes "Microsoft today introduced Windows Azure, its operating system for the cloud. The OS serves as the underlying foundation of the Azure Services Platform to help developers build apps that span from the cloud to the datacenter, to PCs, the Web, and phones. Cloud-based developer capabilities are combined with storage, computational, and network infrastructure services, which are hosted on servers within Microsoft's global data center network."

Matt_dk writes "VASIMR is a new high-power plasma-based space propulsion technology, initially studied by NASA and now being developed privately by Ad Astra. A VASIMR engine could maneuver payloads in space far more efficiently and with much less propellant than today's chemical rockets. Ultimately, VASIMR engines could also greatly shorten robotic and human transit times for missions to Mars and beyond."

Scientists at the University of California Los Angeles are reporting that while some people may think "life begins at 40," all it seems to do is slow down. According to recent research, at age 39 our brain reaches its peak speed, and it's all downhill after that. "The loss of a fatty skin that coats the nerve cells, called neurons, during middle age causes the slowdown, experts say. The coating acts as insulation, similar to the plastic covering on an electrical cable, and allows for fast bursts of signals around the body and brain. When the sheath deteriorates, signals passing along the neurons in the brain slow down. This means reaction times in the body are slower too."

Ant writes "The Telegraph reports that people over 55 who were brought up watching a monochrome TV set are more likely to dream in black and white, even years later. New research suggests that the type of television you watched as a child has a profound effect on the color of your dreams. While almost all under-25s dream in color, many over-55s, all of whom were brought up with B&W sets, often still dream in monochrome. The study, out ot Dundee University, used a small number of subjects under 25 or over 55 and the results suggest that '... there could be a critical period in our childhood when watching films has a big impact on the way dreams are formed ... [B]efore the advent of black and white television all the evidence suggests we were dreaming in color.'"

An anonymous reader writes "The hedge fund investor who prided himself on achieving 1000% returns, Andrew Lahde, wrote a goodbye letter to mark his departure from the financial world. In it, he suggests people think about building a new government model, and his suggestion is to have someone like George Soros fund a new government that brings together the best and brightest minds in a manner where they're not tempted by bribery. In doing so, he refers to how Linux grows and competes with Microsoft. An open source government. How would such a system work, and could it succeed? How long before it became corrupt? Would it need a benevolent dictator (Linus vs. Soros)?"

ThinSkin writes "Just when you thought laser and optical mice were enjoying their reign on mousepads worldwide, Microsoft has to come along and introduces their 'BlueTrack Technology,' a mouse tracking system that aims to work on virtually any terrain short of mirrored and reflective surfaces. ExtremeTech reviews the Explorer Mouse and Explorer Mini Mouse, both of which are powered by Microsoft's newest sensor, to see just how well this technology works. Testing on granite, carpet, marble, and other surfaces, the reviewers were impressed with the responsiveness of BlueTrack, but they also noted that laser mice were competitive on these surfaces as well. Even though the mice didn't get a recommendation from the reviewers (price being a major concern), they did admit that this BlueTrack is the best tracking system available today. MaximumPC has some pictures and a brief technical interview."

snydeq writes "Fatal Exception's Neil McAllister calls for generic VMs divorced from the syntactic details of specific languages in order to provide developers with some much-needed flexibility in the years ahead: 'Imagine being able to program in the language of your choice and then choose from any of several different underlying engines to execute your code, depending upon the needs of your application.' This 'next major stage in the evolution of programming' is already under way, he writes, citing Jim Hugunin's work with Python on the CLR, Microsoft's forthcoming Dynamic Language Runtime, Jython, Sun's Da Vinci Machine, and the long-delayed Perl/Python Parrot. And with modern JITs capable of outputting machine code almost as efficient as hand-coded C, the idea of running code through a truly generic VM may be yet another key factor that will shape the future of scripting."

Ars Technica reports on research out of Cal Tech where scientists were able to create logic gates out of RNA molecules. Thus far, they've demonstrated AND gates and OR gates, with work proceeding on more complicated systems. The work shows promise for ability to easily detect the presence of particular chemicals. The abstract from the scientists' paper is available at Science. Quoting Ars: "Detecting tetracycline isn't especially interesting, but RNA that binds to specific small molecules is actually relatively easy to make; repeated rounds of amplification and selection for binding can evolve these RNAs in a couple of days. This means that, in a matter of days, researchers can grow yeast colonies that glow in response to a variety of chemicals, or even to combinations of chemicals. More complicated circuits should be possible if the ribozymes are inserted into messenger RNAs that encode transcription factors, which could, in turn, regulate genes that encode yet other ribozymes."
