US Army's magic bullet will hang out in mid-air, but won't kill you

By


This is the recipe for peak absurdity in weapons design. One part bazooka round; one part suicidal drone; one part stun round. What the US Army hopes will emerge from that mix is a warhead that can loiter in midair while it hunts a human target -- but won't kill him when it finds him.
That "Nonlethal Warhead for Miniature Organic Precision Munitions" is on the Army's wish list for small business. For good measure, its outline for the weapon relies on a different system, one that's just barely getting off the ground. "This effort will require innovative research and advancements in non-lethal technologies which can be packaged within a very small volume and weight," the Army concedes.
This latest nonlethal weapon is a modification of something called the Lethal Miniature Aerial Munition System (LMAMS), something the Army explicitly compares to a "magic bullet." That warhead "should be capable to acquire a man-size target at the system's combat range, in less than 20 seconds, flying at an altitude of 100 metre[s] above ground," according to the Army's new solicitations for small business. "If conditions for attack are not met, LMAMS will be able to loiter over the target for up to 30 minutes."
Under this modification, the L in LMAMS would be replaced by something very un-L. "The user has expressed a strong need for a non-lethal alternative warhead for these munitions," the Army explains. What it doesn't explain is exactly what kind of non-lethal weapon this should be. (Chances are it won't be a heat ray, since the power generation necessary for one is probably beyond the scope of any warhead.) The Army encourages small businesses to think about "mechanical, such as rubber balls; acoustic; chemical; electrical; or dazzle." (Um, chemical weapons?)
One problem: the LMAMS program is in its infancy. The highest-profile example example of one of its weapons is the Switchblade drone by AeroVironment -- a teeny, tiny guided missile soldiers can direct on a laptop toward a target. Elite troops in Afghanistan are expected to get the first Switchblades -- the first weapon of its kind -- sometime later in 2012.
Give the Army this: the Switchblade does demonstrate that the technology necessary for creating loitering kamikaze weapons is more than theoretical -- as, on a larger scale, does the new-model Tomahawk missile, which can change direction in midair. But non-lethal weapons tend to have more flash than bang. The US Air Force gave up on plans for a dazzler gun in 2008, citing practicality concerns, and the design flaws in the millimetre-wave Active Denial System, a.k.a. the "Pain Ray," have kept it stuck in development for 15 years.
To help incentivise small businesses to outperform those recent disappointments, the Army lists some of the "potential commercial applications" for the non-lethal, loitering bazooka round. They're in your backyard: "crowd control for local law enforcement; border protection for Homeland Security; or temporary incapacitation of non violent criminals for local SWAT teams and/or law enforcement." So if this weapon turns out to be too absurd for the military, there's always the local police station.

Google and Stanford early adopters of Honda Fit EV

By
Honda's first all-electric vehicle is hitting the streets a little early. The  Honda Fit EV  debuted at the Los Angeles Auto Show in November 2011, and it's expected to be     available for lease this summer. However,  Honda announced  that Google and Stanford University got a special early delivery of the tiny EV this week.The Honda Fit EV is equipped with a 20kWh lithium ion battery, and has an EPA estimated driving range of 76 miles. Google added the EV to its  car -sharing service for employees, dubbed the G-Fleet, in    Mountain View, Calif. The search giant maintains several electric and plug-in vehicles that it uses for research and to cart Googlers around town and between buildings on campus. Stanford University also is an early adopter of the Fit EV, but will be using it primarily for research. The university's automotive research department will study the difference in psychological and physical reactions of using battery...

Hand-manipulated objects and transparent displays - the computer desktop of tomorrow

By
A see-through screen, digital 3D objects manipulated by hand, perspective adjustments according to the user's viewing angle - these are the core features of a prototype computer desktop user interface created by Microsoft's Applied Sciences Group. The prototype uses a "unique" Samsung transparent OLED display through which the user can see their own hands to manipulate 3D objects which appear to be behind the screen. A demo video appears to show a working prototype of a computer markedly different from those we use today. Yes it includes a familiar keyboard and trackpad - but these are placed behind the OLED display. The user simply lifts their hands from these input devices to manipulate on-screen (or more accurately  behind -screen) objects, such as selecting a file or window. The video shows the interface in action with a series of program windows stacked behind one another, with the user selecting the desired program by hand, using the depth of the w...

Bioengineers develop smart, self-healing hydrogel

By
Velcro is pretty handy stuff, but imagine if there was a soft, stretchy material with the same qualities. Well, now there is. Scientists from the University of California, San Diego have created a self-healing hydrogel that binds together in seconds, essentially copying the Velcro process at a molecular level. The new material could potentially find use in medical sutures, targeted drug delivery, industrial sealants and self-healing plastics. The secret to the jello-like polymer hydrogel is its "dangling side chain" molecules, that reach out toward one another like long, spindly fingers. When developing the gel, a team led by bioengineer Shyni Varghese ran computer simulations, in order to determine the optimal length for these molecules. The resulting substance is capable of healing cuts made to itself - or of bonding with another piece of hydrogel - almost instantly. The behavior of the material can be controlled by adjusting the pH of its environment. In lab t...
