New Armored Wall System Assembles Like Legos, Could Replace Sandbags In Afghanistan

McCurdy's Armor Dynamic Defense Materials

From Popular Science:

Attention recruits. Those of you landing in Afghanistan in coming months may not have to engage in the sandbag stacking and trench digging usually associated with lowly grunt-dom. An $800,000 investment in an armored wall system known as McCurdy’s Armor could have Marines rapidly erecting 6.5-foot-tall mortar-, RPG- and bullet proof fortresses in less than an hour, saving the days it can take to fortify an area by conventional means and making forward-operating units more nimble.

From Science Daily:

Science Daily (Feb. 9, 2010) — Two patients with rare lesions to the brain have provided direct of evidence of how we make decisions -- and what makes us dislike the thought of losing money.

Researchers at the California Institute of Technology studied a phenomenon known as 'loss aversion' in two patients with lesions to the amygdala, a region deep within the brain involved in emotions and decision-making. The results of the study, part-funded by the Wellcome Trust, are published February 8 in the journal Proceedings of the National Academy of Sciences.

Can Battlefield Robots Take The Place Of Soldiers?

Can battlefield land-robots be made to obey the rules of war?

From The BBC:

Can war be fought by lots of well-behaved machines, making it "safer for humans"? That is the seductive vision, and hope, of those manufacturing and researching the future of military robotics.

With 8,000 robots already in use, they believe they can bring about a military revolution.

Most of the robots currently deployed on land deal with non-combat tasks such as bomb disposal - unlike lethal aerial drones.

But Bob Quinn, who works for the US subsidiary of the British robot manufacturer QinetiQ, says the future promises more armed robots on the battlefield, including driverless vehicles.

Why NASA Picked Stormy Florida

From Christian Science Monitor:

Weather thwarts shuttle launches. But important factors favor this state.

If the space shuttle Endeavour lifts off in the early hours of Feb. 7, it will be the first shuttle launch in more than half a year to leave on time.

Each of the last three missions has been delayed for days or weeks – with one held back by a scheduling conflict and two by stormy weather. Despite its "Sunshine State" moniker, Florida has postponed shuttles due to five hurricanes, two hailstorms, a tropical storm, lightning damage, countless cloudy days, and meddlesome woodpeckers stabbing a fuel tank. And if the temperature goes below 36 degrees F., as it did earlier this month, Cape Canaveral's fickle weather will thwart yet another scheduled blastoff.

Boeing’s New 747-8 Continues A Jumbo Tradition

From Autopia:

EVERETT, Washington — Boeing spent more than five years and hundreds of millions of dollars developing its new 747-8, but in the end the decision on whether to send the company’s biggest aircraft ever down the runway and into the air for the first time rested with the man in the cockpit.

The flight window for the 747-8’s maiden flight opened at 10 a.m. Monday, but Mother Nature had other plans. Paine Field was socked in by low clouds, and the clock was ticking. Mark Feuerstein, Boeing’s chief test pilot for the 747 program — the man who has spent years preparing for the day — had to decide whether to proceed.

The Dawn Of Civilization: Writing, Urban Life, And Warfare -- Discovery Magazine

An extraordinary ancient Syrian settlement shines a light on one of the most important moments in human history.

Joan Oates’s sharp blue eyes spotted something that was not right. Standing on the windy summit of a vast, human-made mound in northeastern Syria, the wiry 81-year-old archaeologist noticed an ugly scar that had been left by a backhoe on one of the smaller mounds ringing the ancient city of Nagar, where she has excavated for a quarter century. Oates had just arrived to begin her latest season at the site, and this blemish on her cherished landscape annoyed her. Two young men on her team volunteered to investigate the damage. They returned, shaken. Jumping into the trench, one of them had come face-to-face with a skull. “Everywhere we looked, there were human bones,” one recalls. “There were an enormous number of dead people.”

From Technology Review:

Autoantibodies could alert doctors to cancer development.

A new screening tool developed by scientists in Denmark may help detect the earliest stages of cancer by taking advantage of the body's own defenses. The researchers constructed a microarray system that analyzes patients' blood for a specific class of immune agents called autoantibodies. These are agents that attack the body's own tissue, targeting what they perceive as "foreign" cells, such as specific molecules on the surface of tumors.

The MV-22 Osprey Finds Purpose In Disaster Relief

From Popular Mechanics:

Can the much-maligned tilt-rotor aircraft earn respect on the job?

USS Bataan—After a couple of days working just under the flight deck of the amphibious assault ship USS Bataan you begin to recognize the signature sounds of various helicopters: The high-pitch rip of an HH-60 Knighthawk, the deep, rapid drum beat of the giant CH-53D Super Stallion or the rhythmic song of a UH-1 Huey. So the crew of the USS Bataan, outside Haiti, knows when something new lands onboard. Seconds after a bass-drum vibration shook the ward-room lounge, an excited Marine officer stuck his head in and announced "The Ospreys are taking off! Let's go up to the top of the island and watch!"

From Popular Science:

New light-emitting electrochemical cells could replace OLEDs.

Graphene may brighten the future more literally than we had originally anticipated, besides merely revolutionizing electronics and Silicon Valley. Swedish and American researchers have transformed the one-atom-thick carbon material into a new, inexpensive lighting component that could give organic light diodes (OLEDs) a run for their money.

From The Telegraph:

New evidence that liquid water lies beneath the surface on the Saturn moonof Enceladus has been discovered by Nasa scientists, suggesting that life may exist.

Nasa's Cassini spacecraft flew through icy plumes created by ice volcanoes and detected negatively charged water molecules, in a clear sign an underground sea exists.

On Earth this short-lived type of ion is produced where water is moving, such as in waterfalls or crashing ocean waves.

Apple iPad Price Cut: Blunder or Brilliance?

From PC World:

If Apple is really considering price cuts on its just-introduced iPad, the best advice is to make them before launch, not after.

Not today, or tomorrow, but a price drop a week--or even a day--before it goes on sale might give the iPad an incredible boost. I will also describe what other businesses can learn from Apple's troubles.

Genetic Disorder Turns Risk-Averse Into Gamblers

The study found that people with a damaged amygdala had a higher inclination to risk losing money as a result of reckless gambling. Alamy

From The Independent:

The brains of people who risk everything when gambling may be wired up differently to those of the naturally cautious, according to a study that appears to have discovered a neurological basis for reckless behaviour.

The research found that people were far more gullible to high-risk gambling when a small but distinct part of their brain had been damaged as a result of a rare genetic disorder. They showed little of the natural aversion to losing something of value that most people are born with.

From The Guardian:

It will soon be half a century since the American astronomer Frank Drake first pointed a radio telescope at the star Tau Ceti in the hope of picking up an extraterrestrial broadcast, and we still haven't heard anything. So is there anyone out there?

Fifty years ago Frank Drake – then a young astronomer from Cornell University – began an experiment that would have profound implications for humanity's understanding of its place in the cosmos. He turned the newly constructed Green Bank radio telescope in West Virginia towards Tau Ceti, a nearby star that is similar to our own Sun.
