My favorite comedy from Bill Nye was Speeeeeeed Walker, a super hero that always adhered to the rules of the International Speed Walking Association: Heal Toe! Heal Toe!
In a December 2010 submission to the Federal Aviation Administration, the FBI asserted that its three drones [“UAS,” or unmanned aerial system, in the above] were safe to fly in domestic skies. In an otherwise heavily redacted document, this one number escaped the censors’ gaze.

"On March 2nd 2014 Flexcoin was attacked and robbed of all coins in the hot wallet. The attacker made off with 896 BTC, dividing them into these two addresses: 1NDkevapt4SWYFEmquCDBSf7DLMTNVggdu 1QFcC5JitGwpFKqRDd9QNH3eGN56dCNgy6 As Flexcoin does not have the resources, assets, or otherwise to come back from this loss, we are closing our doors immediately".
Diggester writes: The days when solid, liquid and gas were the only three states of matter were over when newer states such as plasma and superficial fluid were discovered. It seems like science students will be updating their course notes in the near future, thanks to the discovery of a yet another state of matter. Say hello to Dropleton which comes across as a new sort of puny particle that may possess the postulates of the liquid state of matter.
MTorrice writes: Lithium-sulfur batteries promise to store four to five times as much energy as today’s best lithium-ion batteries. But their short lifetimes have stood in the way of their commercialization. Now researchers demonstrate that a sulfur-based polymer could be the solution for lightweight, inexpensive batteries that store large amounts of energy. Battery electrodes made from the material have one of the highest energy-storage capacities ever reported
kc123 writes: From Bloomberg: Rolls-Royce’s Blue Ocean development team has set up a virtual-reality prototype at its office in Alesund, Norway, that simulates 360-degree views from a vessel’s bridge. Eventually, the London-based manufacturer of engines and turbines says, captains on dry land will use similar control centers to command hundreds of crewless ships. Drone ships would be safer, cheaper and less polluting for the $375 billion shipping industry that carries 90 percent of world trade, Rolls-Royce says.
An anonymous reader writes: A high school student makes a great case for moving fossil-fuel based cars to an ammonia-based fuel--a mix anywhere from 10% ammonia to 80% ammonia. This is a pretty compelling article that examines not only ammonia as a fuel, but how it can be produced in such a way that the carbon dioxide emissions coming out of your car would be close to zero. The technology already exists!
sciencehabit writes: President Barack Obama yesterday used a visit to drought parched California to announce that his 2015 budget request to Congress, to be released in early March, will include a proposal to create a $1 billion “Climate Resilience Fund.” It is not yet clear exactly how much of the proposed funding would be entirely new money, how much would be shifted from cancelled programs, and how much is already earmarked for programs that would be folded into the new fund. White House officials have also been vague about which agencies, programs and activities would be included in the fund. Some hints, however, can be gleaned from a report released this past March by the President’s Council of Advisors on Science and Technology (PCAST). In a letter to Obama, PCAST suggested that the Department of Homeland Security might be put in charge of developing domestic “climate preparedness plans,” while the Department of Defense could play “the lead role for involving events overseas that affect our national security.”
sciencehabit writes: This week, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California announced an important milestone on the road to achieving ignition, which could lead to producing controlled fusion reactions here on Earth. But NIF isn’t just about harnessing the energy of the stars—it’s about learning how stars produce their energy in the first place. In fact, pushing matter to extreme pressures and temperatures lets scientists explore all sorts of unanswered questions. At the annual meeting of AAAS in Chicago four physicists sat down with Science Magazine to discuss NIF’s basic science potential and what experiments they would do if they had the laser all to themselves.
Nerval's Lobster writes: The author of the Patriot Act has warned that the legal justification for the NSA’s wholesale domestic surveillance program will disappear next summer if the White House doesn’t restrict the way the NSA uses its power. Section 215 of the Patriot Act will expire during the summer of 2015 and will not be renewed unless the White House changes the shocking scale of the surveillance programs for which the National Security Administration (NSA) uses the authorization, according to James Sensenbrenner Jr. (R-Wis.), an original author of the Patriot Act and its two reauthorizations, stated Washington insider-news source The Hill. “Unless Section 215 gets fixed, you, Mr. Cole, and the intelligence community will get absolutely nothing, because I am confident there are not the votes in this Congress to reauthorize it,” Sensenbrenner warned Deputy Attorney General James Cole during the Feb. 4 hearing. Provisions of Section 215, which allows the NSA to collect metadata about phone calls made within the U.S., give the government a “very useful tool” to track connections among Americans that might be relevant to counterterrorism investigations, Cole told the House Judiciary Committee. The scale of the surveillance and lengths to which the NSA has pushed its limits was a “shock” according to Sensenbrenner, who also wrote the USA Freedom Act, a bill to restrict the scope of both Section 215 and the NSA programs, which has attracted 130 co-sponsors. Senate Judiciary Committee Chairman Patrick Leahy (D-Vt.) has sponsored a similar bill in the Senate.
schwit1 writes: Curious why Michael Dell was so eager to take the company he founded private? So he could do stuff like this without attracting too much attention. According to the Channel Register, the recently LBOed company is "starting the expected huge layoff program this week, claiming numbers will be north of 15,000." Of course, with a private sponsor in charge of the recently public company, the only thing that matters now is maximizing cash flows in an environment of falling PC sales, a commoditisation of the server market and a perceived need to better serve enterprises with their ever-increasing mobile and cloud-focused IT requirements — things that do not bode well for Dell's EBITDA — and the result is perhaps the largest axing round in the company's history. But at least the shareholders cashed out while they could.
KentuckyFC writes: In May last year, Google and NASA paid a reported $15 million for a quantum computer from the controversial Canadian start up D-Wave Systems. One question mark over the device is whether it really is quantum or just a conventional computer in disguise. That's harder to answer than it sounds, not least because any direct measurement of a quantum state destroys it. So physicists have to take an indirect approach. They assume the computer is a black box in which they can input data and receive an output. Given this input and output, the question is whether this computing behaviour can be best reproduced by a classical or a quantum algorithm. Last summer, an international team of scientists compared a number of classical algorithms against an algorithm that relies on a process called quantum annealing. Their conclusion was that quantum annealing best reproduces the D-Wave computer's behaviour, a result that was a huge boon for the company. Now a group from UC Berkeley and IBM's Watson Research Lab says it has a found a classical algorithm that explains the results just as well, or even better, than quantum annealing. In other words, the results from the D-Wave machine could just as easily be explained if it was entirely classical. That comes on the back of mounting evidence that the D-Wave computer may not cut the quantum mustard in other ways too. Could it be that Google and NASA have forked out millions for a classical calculator? Just possibly, yes.
Of course you can eliminate all sounds, duh. You just have to make sure the fans are blowing supersonic air. Sound can't travel upstream supersonically.
