Darpa's Self-Aiming "One Shot" Sniper Rifle Scheduled for Next Year

A sniper crouches near an open window and zooms in on his target, who sits a half-mile away. He peers through a scope and holds his breath, preparing to squeeze the trigger. But it's windy outside, and he can't afford a miss. What to do?

A new DARPA-funded electro-optical system will calculate the ballistics for him, telling him where to aim and ensuring a perfect shot, no matter the weather conditions.

Darpa Moves a Step Closer to Its Flying Humvee

In the spring, the futurists at Darpa rethought troop transport. Instead of adding armor or changing the shape to deflect bomb blasts, the agency reasoned, why not let it leap into the sky at the first sign of danger or inconvenience? That's exactly what Darpa's "Transformer" project is supposed to be: a mashup of a helicopter, plane and armored truck.

New Audio Teen-Repellent

Gallery Place business owners in the Chinatown area of Washington DC are using a new approach to chasing away loitering teenagers: zapping them with a device that emits a high-pitched, headache-inducing sound that only young ears can hear.

The Mosquito, as the $1,000 device is called, is apparently annoying not only its intended targets, but also some of their sharp-hearing elders.

Tiny Thorium Reactors Could Wean World Off Oil

An abundant metal with vast energy potential could quickly wean the world off oil, if only Western political leaders would muster the will to do it, a UK newspaper says today. The Telegraph makes the case for thorium reactors as the key to a fossil-fuel-free world within five years, and puts the ball firmly in President Barack Obama's court.

My New Home in Far North Dallas

I have been on the waiting list for two terrific apartments for several months. It took so long for me to find an apartment because I'm picky. I demanded a top floor apartment, preferably a corner unit, with a good view in a vibrant neighborhood. My favorites were the Ravello in Uptown near the Dallas arts and entertainment center and Turnberry Isle located beside the Prestonwood Country Club golf course.

I am now a Turnberry Isle resident. Turnberry is less than 10 minutes from the Galleria and even closer to Addison's nightlife. There are DOZENS of great restaurants nearby. And I'm only 20 minutes to my options classes in Uptown. The rent on my 2-bedroom top floor corner unit apartment costs 60% less than my Fairfax VA 1-bedroom apartment.

The photos below were taken from my balcony that overlooks the 11^th hole of the golf course.
This is my living room. The living room and master bedroom also overlook the golf course. I'm going to turn the master bedroom into a large office as soon as I buy a desk and some bookshelves.

Spinal-Fluid Test Confirmed to Predict Alzheimer's

Download a Movie from iTunes in Less than 1 Second

That's the promise of a research breakthrough from Intel that combines silicon chips and lasers to transmit data at 50 gigabits per second — and someday, maybe as fast as a terabit per second.

The 50-Gbps speed is enough to download an HD movie from iTunes, or up to 100 hours of digital music, in less than a second.

The technology, known as silicon photonics, can be used as a replacement for copper wires to connect components within computers, or between computers in data centers. Over the next two years, Intel hopes to perfect the technology by improving the efficiency of the lasers, as well as the packaging and assembly of the silicon chips and the manufacturing techniques needed to churn out millions of these modules.

Telemedicine Comes Into Its Own

"Telemedicine — providing care using advanced communications technology may be coming into its own with a little help from Uncle Sam. The Obama administration recently awarded $795 million in grants and loans for 66 new broadband projects. Most of these projects will involve using videoconferencing equipment to allow doctors to consult on medical procedures or examinations remotely."

NOAA interactive map tracks Gulf oil spill

Geoplatform.gov/gulfresponse employs the Environmental Response Management Application (ERMAR) a web-based GIS platform developed by NOAA and the University of New Hampshire's Coastal Response Research Center. ERMA was designed to facilitate communication and coordination among a variety of users - from federal, state and local responders to local community leaders and the public.

The mapping tool includes only those vessels equipped with the automatic identification system and therefore is not representative of all the vessels supporting the largest oil spill response and recovery operation in U.S. history.

Army’s Self-Driving Trucks Let Humans Watch for Bombs

As insurgents in Afghanistan target the U.S. military's soft underbelly — its long logistics lines — trucking materiel through war zones has become an increasingly dangerous mission. One U.S. Army solution? Self-driving trucks that let the humans behind the wheel look out for bombs, instead.

3-D Printers Make Real Items From Design Downloads

Home computer printers gave people the ability to produce bank statements, concert tickets, holiday cards and party invitations at the touch of a button.

But what if you wanted to "print out" a dinner plate, the leg of an armchair or an eyeglass frame? It may sound far-fetched and futuristic, but machines that can do this -- popularly known as 3-D printers -- are poised to enter the home electronics market.

PERSONAL NOTE: These devices remind me of the "3D printer" that my old Army agency has that can produce solid 3-D color models from digital geospatial information. The 3D printer is used to create color models of cities, mountainous areas and other complex terrain around the world in support of military operations and other applications. Some visiting Congressmen have requested models of cities or other areas in their home districts.

Mark Twain To Reveal All After 100 Year Wait

One of Mark Twain's dying wishes is at last coming true: an extensive, outspoken and revelatory autobiography which he devoted the last decade of his life to writing is finally going to be published one hundred years after his death. Twain, the pen name of Samuel Clemens, left behind 5,000 unedited pages of memoirs when he died in 1910, together with handwritten notes saying that he did not want them to hit bookshops for at least a century, but in November, the University of California, Berkeley, where the manuscript is in a vault, will release the first volume of Mark Twain's three-volume autobiography. Scholars are divided as to why Twain wanted his autobiography kept under wraps for so long, with some believing it was because he wanted to talk freely about issues such as religion and politics. Michael Shelden, who this year published Man in White, an account of Twain's final years, says that some of his privately held views could have hurt his public image. 'He had doubts about God, and in the autobiography, he questions the imperial mission of the US in Cuba, Puerto Rico and the Philippines,' says Shelden. 'He's also critical of [Theodore] Roosevelt, and takes the view that patriotism was the last refuge of the scoundrel. Twain also disliked sending Christian missionaries to Africa. He said they had enough business to be getting on with at home: with lynching going on in the South, he thought they should try to convert the heathens down there.'

Toyota, Tesla Burnish Their Images by Teaming Up

This is a very interesting article. Suddenly Tesla, the new EV auto company, becomes more believable as it gets Toyota components and an unused California auto plant!

The Japanese giant and the Silicon Valley upstart stunned everyone with Thursday's announcement that they'll work together on electric vehicles and components. Toyota will buy $50 million worth of stock when Tesla Motors goes public, and it gets a closer look at proven EV tech. Tesla gets a shuttered Toyota factory in Northern California to build the Model S sedan and expert advice on how to engineer and build a mass-market car.

Researchers Restore Youthful Memory in Aging Mice

"German neuroscientists have made a breakthrough in 'age-related cognitive decline', a common condition that often begins in one's late 40s (especially declarative memory — the ability to recall facts and experiences). Their new study identifies a genetic 'switch' for the cluster of learning and memory genes that cause memory impairment in aging mice. By injecting an enzyme, the team 'flipped' the switch to its on position for older mice, giving them the memory and learning performance they'd enjoyed when they were young. Now the team ultimately hopes to recover seemingly lost long-term memory in human patients."
