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.
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.

We took a trip down to Cedar Park, Texas to visit the fine folks at ETS Lindgren, a company that builds anechoic chambers and testing solutions for things like smartphone antennas. We learned a lot, and at the end of the day decided that we wanted to see if they’d allow us to test the iPhone 4 antenna by itself, and then test those results against an iPhone 4 inside of the ElementCASE Vapor 4.
The Vapor 4 is an $80 case that looks great, but we’ve been hearing that users were having issues with dropped calls and data signal loss. We wanted to know if the case was the reason, or if it was the iPhone 4 antenna itself. Get a look at our scientific test, and the results, in this episode!
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 future of stealthily cloaked super soldiers running around with nano machines injected in their bodies is closer than we think, thanks to Elena Semouchkina. Elena is an associate professor of electrical and computer engineering at Michigan Tech, who has found a way to cloak objects by using carefully thought out materials and shapes to produce the magnetic resonance necessary to bend infrared light around objects.
While not yet able to do so in visible light, Elena’s team has found a way to cloak metallic cylinders using metamaterials made of chalcogenide glass. “Starting from these experiments, we want to move to higher frequencies and smaller wavelengths,” states one researcher.
While far from being perfected, Elena’s new theory in cloaking puts us in the ball park for a stealthy future. Perhaps we will bear witness to the implementation of the practical usage of cloaking devices in the near future. Solid Snake, eat your heart out.

If you’re a child of the 80’s like me, some of your fondest memories revolve around movies like ‘Real Genius’ or Hughes-ian bits of brain candy like ‘The Breakfast Club’ or, better yet, ‘Weird Science’. Oh, for the halcyon days of wrist-watch calculators and pocket protectors—when nerds first began to rattle the bars of their cages and shout their skinny-armed superiority from atop a mound of servers—the true first days of ‘nerd-chic’. These beer-steins of science are hand-crafted from Pope Scientific bench top dewar flasks which should ring-true for any hard core science geeks out there and help you drink your way back to your childhood. So strap a bra to your head, fire a laser through the wall, and fill your favorite college prof’s house with popcorn. Then get trashed in the name of SCIENCE!!!!
Today, Touch International is releasing its Windows 7-compatible Multi-Touch Analog Resistive (MARS) Touch Screen Module. The MARS module supports 10-finger touch and is easily modifiable, featuring superior drift-free performance, outstanding optical clarity and a fast and accurate response time, it also allows for True Touch Gesture and palm rejection while working with bare/gloved/bear-gloved fingers or a pointing device. The MARS module can also transform to a virtual keyboard or even a touch-screen piano as well. Don’t worry, I’m sure that you can figure out a way to play Scrabble on Facebook with it as well. Just remember to wipe your hands before use, Cochise; can you imagine if you had to actually view a computer screen through the grime you’ve accumulated on your mouse pad? It would be like trying to look through frosted-glass, or the windshield on your moldy ‘82 Buick Regal. Don’t lie, we’ve seen you driving it.
At TED 2010, Bill Gates gave a talk that laid out his vision and hope for the world’s energy future, citing the need for what may amount to a miracle to avoid planetary catastrophe, with the goal of zero carbon emissions across the globe by 2050. One of the more interesting, and most talked about, moments involves Bill take out a jar of fireflies (at last years talk, he used mosquitos) to make a point. Definitely a great video to take in, and it gives you a nice idea of what Mr. Gates is up to these days.
Regardless of how annoying he might be, David Blaine’s TEDMED talk on how he set the world record for holding his breath underwater for 17 minutes is pretty phenomenal. Definitely interesting to see the different ways he thought of to do it as an illusion, using various technological methods and DIY gadgets, before finally deciding that he would do it for real. This one is definitely worth watching, and also worth not trying at home. It’s kind of ridiculous.
These days, everything from our mobile phones to our iPods have WiFi capability, so why not put it in a device where it really matters, like a pacemaker? Apparently, a New York woman was the first to receive such a device, and it is designed to upload any troubling stats tol her doctor should it pick up anything abnormal.
We like seeing technology used to keep people safe, and this saves time as well, since most of her normal tests are now done on the fly, with results delivered without an appointment needing to be made.
