NASA’s X-43A Scramjet Breaks Speed Record
NASA’s X-43A research vehicle screamed into the record books again Tuesday, demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data from the scramjet-powered research vehicle show its revolutionary engine worked successfully at nearly Mach 9.8, or 7,000 mph, as it flew at about 110,000 feet.
After a quick fact check, this is to correct an earlier post about the SR-71 being the fastest plane on Earth. But, still, ‘Murica!
The fastest plane on Earth - Lockheed SR-71 Blackbird
Maximum speed: Mach 3.3 (2,200+ mph, 3,530+ km/h, 1,900+ knots) at 80,000 ft (24,000 m)
Range: 2,900 nmi (5,400 km)
Ferry range: 3,200 nmi (5,925 km)
Service ceiling: 85,000 ft (25,900 m)
Rate of climb: 11,810 ft/min (60 m/s)
1964 - 1999
Still, to this day, the fastest plane on Earth. ‘Murica!
Last year, researchers at the Ecole Polytechnique Federale de Lausanne in Switzerland announced plans to outfit a male patient with an artificial hand connected directly to the patient’s nervous system, enabling him to not only control the artificial hand, but to feel via touch signals embedded in the skin of the prosthetic.
Around the world, advancements in prosthetics are accelerating. In the United States, the Food and Drug Administration has approved a new artificial retina technology known as the Argus II that can restore partial sight to people suffering from a specific type of blindness known as retinitis pigmentosa.
Scientists at the University of Southern California at Los Angeles believe they are close to being able to restore a person’s memory capabilities with microchips inserted in the brain, while a San Diego-based company expects to be able to create a human liver via 3D printing technologies sometime in 2014.

Samsung gives us a glimpse of the future via a prototype of their flexible OLED screen, which paves the way for everything from foldable phones to tablets that you can roll up like a newspaper.
THIS CHANGES EVERYTHING
why is the necessary? like really, give me one reason
ummmmm so you don’t break your shit maybe? so that half your bag isn’t taken up by a tablet or phone? so that you migh not even NEED a bag
IT’S THE FUCKING FUTURE. FUCKING APPRECIATE IT
Don’t mess with your phone around toilets.
19% of you have lost a phone to the toilet ghoulie:
The kickstarter is funded, but you can still donate and get your hands on your own pen.
super, super fascinating
You know what
With this, I could make circuits and pretend it’s an arcane geometric magic.
From the biorobotics lab at Carnegie Mellon University comes this modular snake robot. According to the researchers, using the form of a snake allows the robot to navigate freely in many different environments, including networks of pipes and the gaps between walls. It can also climb stairs and trees.
Even CEO Elon Musk thinks Tesla Motors Inc.’s stock is overvalued.
“Volvo Concept Coupe may see limited production”
Despite the impressive production debuts from Porsche and BMW at this year’s Frankfurt Motor Show - the918 Spyder and the i8, respectively - there was one car that captured the attention of the press and the public alike, enough so that we awarded it our overall top pick of the show: the Volvo Concept Coupe. Most concepts never make it to production, but the car’s reception has been so positive that Volvo’s board of directors is considering to produce it in limited quantities, Auto Bild reports. Italian coachbuilder Bertone could handle the limited production run.
Styled after the classic P1800, the Volvo concept was similar to the new Porsche and BMW in that it was equipped with a high-performance hybrid drivetrain. But Volvo took a different route from there, giving the sleek coupe a turbocharged and supercharged 2.0-liter four-cylinder engine paired with an electric motor at the rear axle. All in, the combo is good for 400 horsepower and 490 pound-feet of torque.
“We chose to call this model LaFerrari,” declared Ferrari’s President, Luca di Montezemolo, “because it is the maximum expression of what defines our company – excellence. Excellence in terms of technological innovation, performance, visionary styling and the sheer thrill of driving. Aimed at our collectors, this is a truly extraordinary car which encompasses advanced solutions that, in the future, will find their way onto the rest of the range, and it represents the benchmark for the entire automotive industry. LaFerrari is the finest expression of our company’s unique, unparalleled engineering and design know-how, including that acquired in Formula 1.”
For Ferrari the development of a limited-series special like the LaFerrari represents an opportunity to experiment with all the technological solutions that will later filter down onto the production cars. Of particular significance in this context is the introduction of the hybrid system which, making full use of the Scuderia Ferrari’s F1 KERS know-how, has resulted in a solution that exalts Ferrari’s fundamental values – performance and driving thrills. The hybrid technology used, known as HY-KERS, represents the perfect combination of maximum performance and lower emissions. LaFerrari in fact emits just 330 g/km of CO2 but without resorting to electric-only drive which would not fit the mission of this model. The HY-KERS system is, however, designed so that in future applications a car can be driven using exclusively electric power for a few kilometres and, during development testing, a full-electric version of LaFerrari achieved just 220 g/km of C02 emissions on the combined cycle.
Chickens are like nature’s steady-cams. They posses a remarkable ability to keep their heads stable even as their bodies move around. And it all has to do with their eyes.
The anatomic feature is demonstrated to great effect in this newly released Mercedes commercial, which is presumably for some stability feature.
Pretty cool, right? Chickens – like most birds – lack the eye-control necessary to keep their gaze fixed on a stationary object while the rest of their body is moving. In humans, these compensatory adjustments are handled by the vestibulo-ocular reflex (VOR), an involuntary eye-movement that keeps your vision stabilized when you move your head. Lacking the oculomotor control that we humans possess, chickens have evolved to offload these compensatory adjustments to the muscles of the head and neck, instead. The result, as you now know, looks like this:
Or like this:
Lots of birds do this. If you’ve ever seen a pigeon bob its head as it walked around, you’ve seen a bird compensate for the movement of its body for the sake of its vision (or, in scientist speak, you’ve seen "an optokinetic response to stabilize the retinal image"). Remember the Rotate Your Owl video? Same thing.
