"But the Obama 2011 budget kills Constellation. Instead, we shall have nothing. For the first time since John Glenn flew in 1962, the United States will have no access of its own for humans into space -- and no prospect of getting there in the foreseeable future."
Keith's note: Um, check your facts next time. First: America did indeed have the ability to launch people on Mercury-Atlas missions after John Glenn flew - and those missions were launched. Second: there was a 6 year gap between Apollo-Soyuz in 1975 and STS-1 in 1981. We had no way to send humans into space during that time. And, FWIW, between the end of Mercury and the beginning of Gemini, we had no access, and between Gemini 12 and Apollo 7 we had no access to space. Between STS-107 and STS-114 ... and so on. Gaps are not a new thing.
Of all the xkcd comics, it's the Valentine's Day ones that are always my favorites. Even when they're bittersweet like this one.

I suppose the lesson is to forget romance once science comes into the picture. [xkcd]
Bad Valentine is our own special take on the beauty—and awkwardness—of geek love.
To all my friends and colleagues in China and to all CR4 members, staff and guests, I wish you a happy AND PROSPEROUS Lunar New Year and wish you ALL good fortune for the Year of the Tiger.
You're looking at a mosquito who got taken down mid-flight by a "Death Star" laser gun designed by Nathan Myhrvold. The malaria-carrying pest never saw it coming, but you can watch everything happen over and over again in this video.
The idea behind the "Death Star" laser is that it could be used to control mosquito populations in developing countries in hopes of reducing the number of deaths due to malaria, a disease frequently carried by the flying insects. The device was shown off during the TED 2010 conference and does in fact appear to be capable of tracking and killing mosquitoes. Oh, and it was built out of parts found on eBay. [Wired]

Yes, Google will plan my wedding one day. Or at least I might use the wedding planning templates in Google Docs to organize things while wishing that Sergey Brin and Larry Page would personally plan my bachelorette party.
Right in time for the cheesiest of all romantic holidays, Google has partnered with Style Me Pretty to provide 20 different customizable wedding planning templates through Google Docs. There's a template for nearly everything from writing vows to sorting out seating arrangements.
Not that I'm ungrateful to Google for assisting me in in becoming a ball-and-chain one day, but geez. Getting into the wedding business seems a bit too much. Even for the Big G. [Google Blog via TechCrunch]

Fred Morrison didn't cure a disease, go to the moon, or invent some high-tech gadget. But he made many of our lives just a bit happier with a simple toy that prompted dreams of flying saucers and sparked intramural games.
According to his son, "old age caught up" with Morrison as he dealt with a battle against cancer. Yet somehow, this remark appears to be the only sad line in Morrison's obituary.
The man's life sounds like it contained as much joy as he brought to children and adults around the world with his invention. In fact, even the events which led to the creation of what is now known as a Frisbee sound happy:
Morrison and his future wife, Lu, used to toss a tin cake pan on the beach in California. The idea grew as Morrison considered ways to make the cake pans fly better and after serving as a pilot in World War II, Morrison began manufacturing his flying discs in 1948.
From there the simple plastic disc would change name from "Pluto Platter" to "Frisbee," but it would remain an staple in memories of summers in the park, beach games of Frisbee golf, and late night Ultimate Frisbee competitions.
So, while Fred Morrison's passing is a sad event, it's heartwarming to hear that he led a good life as he gave us an excuse to laugh and giggle as we send pieces of plastic whizzing through the air. [Yahoo]

Next week, for the first time, the public will be able to see how our government might respond to a full-fledged act of cyber terrorism, in a simulation that will include top intelligence and security officials.
On February 16, the Bipartisan Policy Center-hosted event, dubbed Cyber ShockWave, will assemble many top officials in the "White House situation room"—recreated by set designers in a conference room at the Mandarin Hotel—to respond to a multifacted cyber attack of which they will have no previous knowledge.
The attack, designed by security experts and embellished by professional scriptwriters (really), will unfold dynamically throughout the course of the simulation. The participants, including former Director of National Intelligence John Negroponter and former Homeland Security Advisor Fran Townsend among others, will have to figure out a course of action on the fly.
The fun part: we'll get to see how they do. Though the government has held similar simulations in the past, this will be the first time the process will be open to the public. CNN camera crews will be on location, shooting video that will run in the days following.
I'm curious to see how this group of people who are, of course, quite intelligent, but also, you know, quite old, respond to a fully-realized cyber attack. Hopefully they'll be able to sort out their firewalls from their Firefoxes. [The Atlantic via Computer World UK]

Breakthrough holds potential to deliver more energy at a fraction of the cost.
Arizona State University scientists have come up with a new twist in their efforts to develop a faster and cheaper way to read the DNA genetic code. They have developed the first, versatile DNA reader that can discriminate between DNA's four core chemical components - the key to unlocking the vital code behind human heredity and health.

A simple one-step process that produces both n-type and p-type doping of large-area graphene surfaces could facilitate use of the promising material for future electronic devices. The doping technique can also be used to increase conductivity in graphene nanoribbons used for interconnects.
A team of chemists from the University of New Hampshire has synthesized the first-ever stable derivative of nonacene, creating a compound that holds significant promise in the manufacture of flexible organic electronics such as large displays, solar cells and radio frequency identification tags.
