The space shuttle Discovery undocked from the International Space Station for the last time this morning and started its two-day journey back to the Kennedy Space Center.
The shuttle fired its jets to separate from the ISS at 8:37am Eastern, NASA said. Discovery is scheduled to land at 11:58am on Wednesday; at this point, weather conditions are favorable.
Overall, the astronauts engaged in seven days, 23 hours, and 55 minutes worth of joint activities with the ISS crew. This is Discovery's 39th and final mission.
The crew received a special wake-up call at 3:23am this morning: the theme from "Star Trek" and a recorded message from actor William Shatner. "Space, the final frontier. These have been the voyages of the Space Shuttle Discovery. Her 30 year mission: To seek out new science. To build new outposts. To bring nations together on the final frontier. To boldly go, and do, what no spacecraft has done before," Shatner said.
There is going to be a lot of debate over the fact that American students are again falling behind in their education. According to National Assessment of Educational Progress, American children are nothing less than pathetic when it comes to understanding science.
This whole mess will be blamed on all sorts of things, probably all valid. But who, besides me, is going to blame the computer? Has anyone noticed that ever since the computer was brought into the classroom, student test scores have been falling? Does anyone find this coincidence weird? After all, the computer is, in itself, a teaching machine, of sorts.
Over the years, I've seen a lot of quasi-teaching software and educational software companies come and go, but can you name one large or middle-sized software company that specializes in educational software for children in grade school now? Just try to name one.
The biggest software company in the world, Microsoft, used to have some educational software sold under its discontinued Home brand, but I have no idea what became of it. The company, along with the Gates Foundation, promotes the idea of computers in the classroom, but it seems more of a ploy to make kids comfortable using Windows than anything else.
For science education, the greatest thing a computer can do is to show scientific principals in a way no blackboard or discussion could ever do, with graphical representation and full motion animation. You'd think that with all the computers that have been installed in school that American kids would be wizards by now. But no.

Astronaut Douglas H. Wheelock, the man responsible for the first FourSquare check-in from space, has been brought social media technology into his explorations again by tweeting some of his observations from high above the planet, revealing some stunning images over the past few days. Here are just a few of the beautiful Earth images Wheelock captured during his journey in space. Above is the Isle Juan de Nova in the Mozambique Channel between Madagascar and the African mainland.
DARPA is looking to get their hands on soldiers minds from the outside in, by using a gadget that installs in the helmet to regulate things such as alertness, cognition, pain, and psychiatric well-being.
William Tyler, a neuroscientist from Arizona State University has been working with funds from the Army Research Laboratory for several years, and his work has caught the eye of DARPA.
The mind-control device basically works through a “transcranial pulsed ultrasound” method to stimulate brain circuits from outside of the skull. This is much more convenient than other deep-brain approaches that require invasive surgery to implant electrodes and the like. Furthermore, the technology has proven capable of penetrating deep brain regions, and can zero in on specific brain zones as small as two millimeters.
The device fits snugly into a soldiers helmet and is controlled by a microcontroller. The ultrasound of the device stimulates different brain regions to improve soldier alertness and cognition, and relieve stress and pain, and other traumatic brain injuries.
We’re not too far off from a Metal Gear Solid universe after all.

The world’s first operation and anesthesia done by an all robot team was conducted at Canada’s McGill University Health Centre. The operation being one of extreme delicateness, a prostatectomy, was handled by two robots: DaVinci, a surgical robot, and McSleepy, an anesthetic robot. Both of whom were controlled by a team of surgeons from a workstation with 3D HD video control.
The robots allowed the team of surgeons to work with a precision not capable of by humans alone, allowing for a more precise and safe operation. The surgical team is planning to use this project to test more all-robotic surgery and anesthesia routines on more patients in different surgical situations. We are assured that the robots will not replace the doctors, but will only augment the surgical team to perform to their highest capabilities.

It’s always good news to hear of a military device intended for war that isn’t branded “death from above,” and that actually saves lives instead of taking them. This can be attributed to the researchers at the University of Michigan who have created a new way to protect helicopters from incoming missile up to 1.8 miles away. What’s different about this missile defense is that it uses a laser based technology to “blind” incoming missiles instead of destroying them. This is done by using a mid-infrared super continuum laser that takes on the heat properties of a helicopter, confusing the missile and causing it to lose “sight” of the helicopter. The device has no moving parts, giving it a long life span on the adverse conditions of aircraft operations. Mohammed Islam, a professor in the Department of Electrical Engineering and Computer Science stated: “The laser-based infrared countermeasures in use now for some aircraft have 84 pieces of moving optics. They couldn’t withstand the shake, rattle and roll of helicopters. We’ve used good, old-fashioned stuff from your telephone network to build a laser that has no moving parts.” This technology has enabled University of Michigan to start a company called Omni Sciences, funded up to $1 million from the Army and DARPA, to develop a second generation version.

The term ‘smartphone’ may be a tad misleading according to the recently published New York Times article, “Digital Devices Deprive Brain of Needed Downtime”. This is to say that frequent use of digital media can disrupt your brain’s downtime - a necessary component of internalizing information. Without this downtime, the brain has no chance to process information previously learned, resulting in cluttered, inattentive minds.
Chances are there are more than a few of you reading this article while accomplishing some cardio riding your local gym’s indoor bike, or while in class when you really should be listening to your professor’s first lecture of the semester (but don’t stop reading now on account of that!). While having a digital device handy is excellent for spicing up mundane moments, or for capturing your mind away from the tedium of exercising, it does come at a price.

Imagine, if you will, sitting in the local coffee shop waiting for your ever so tardy girlfriend to show up before your lunch break ends. Suddenly, she is right in front of you, only not in the way you had hoped. It’s a hologram, beaming straight from your cellphone right before your eyes. Her digital representative a fully rendered three dimensional image of her informing you that she will be there in 5 minutes. No, this is not science fiction - it’s the future. And the future is eye popping.
With the demands of technology growing by the second, our everyday bandwidth needs are increasing exponentially. Cisco and Verizon are both anticipating a quadruple increase in bandwidth requirements by the year 2014! This tremendous surge in our bandwidth needs can be attributed largely in part to the burgeoning 3D television market, as well as the growing use of streaming HD video.

Sick of entering a PIN every time you turn on your phone? Want something a bit more futuristic to go with the vastly improved OS of your smartphone? The University of Manchester has the answer - facial recognition.
In order to keep your identity safe in the very likely situation of misplacing your phone, the University of Manchester has created a sophisticated facial recognition technology called the Active Appearance modeling technique that locks in and tracks twenty-two of your facial features, even when upside down. The facial recognition technology was created as a way to access social media sites securely through your smartphone, but no word yet as far as how quickly it works in action. Check out the video after the jump.
