SAN FRANCISCO--If you've ever taken Lincoln Boulevard through the Presidio here, you almost certainly didn't know that you passed within feet of one of the best-preserved World War II-era anti-aircraft machine gun nests in the country.

In fact, all around the Presidio are dozens of these original trenches and fox holes, most of which are completely grown over with weeds and other vegetation, but many of which still have the pillars on which Army crews once mounted their .50 caliber guns in preparation for an aerial or sea-based attack that, thankfully, never came.

We've seen clothing that protects against radiation. Now researchers in Pennsylvania are working on patches that can measure the intensity of explosions on the battlefield and alert medics.

A University of Pennsylvania team is developing a "blast badge" that can show how hard soldiers are hit when exposed to explosives on the battlefield.

Described in an online issue of NeuroImage, the project involves the creation of nanoscale pores and columns using holographic lithography. The structures respond to a shock wave by changing color, indicating intensity, and can be applied as a thin film.

The badges are lightweight, … Read more

People serving in the U.S. military now have their own Web site where they can upload, share, and watch videos.

Announced yesterday, the new MilTube site has been set up as a safer, more secure alternative to YouTube, with content protected behind firewalls. As such, it's designed to serve the interests of military personnel who want to share videos but also satisfy the concerns of the Department of Defense (DOD), which has never been comfortable with access to commercial social network and sharing sites.

"Video is an extremely powerful tool for storytelling and sharing information among personnel,&… Read more

Soldiers may soon be able to avoid an all too common injury associated with modern warfare, if a new helmet and visor design make it to the field.

In Iraq and Afghanistan, the most common military injury is known as "blast-induced traumatic brain injury." Some 130,000 U.S. service members deployed in Iraq and Afghanistan have sustained traumatic brain injuries (TBIs) as a result of explosions, according to the Department of Defense, which can result in concussions, long-term brain damage, and death. (And that number could be even higher.)

So a team of researchers at MIT have … Read more

In a very 21st-century spin on the old World War II adage "loose lips might sink ships," an Associated Press report Wednesday claims that the U.S. Air Force is concerned about troops' use of geolocation services like Foursquare and Facebook Places and the possibility that it could reveal the location of U.S. forces in war zones.

Military authorities in the U.S. and other countries have already made warnings about social networking in general, claiming that it's all too easy for sensitive information to be exposed inadvertently. The Department of Defense had been considering banning the use of social media entirely (… Read more

One-ninth of the American ICBM strike force went offline on Saturday, according to a report on the Web site of the U.S. magazine The Atlantic, as a series of control errors multiplied beyond the ability of engineers to compensate.

The squadron of 50 missiles affected is stationed at F.E. Warren Air Force Base in Wyoming, said the report. The weapons are controlled by five launch control center computers (LCCs), which periodically interrogate the on-board guidance systems of the weapons to confirm their status. According to the report, one LCC began to ping the missiles out of sequence, causing … Read more

Algae biofuel producer Solazyme announced Wednesday it's delivered 20,000 gallons of algae-based shipboard fuel to the U.S. Navy.

Solazyme's Soladiesel Renewable Naval Distillate fuel will go toward the Navy's ambitious goal of getting 50 percent of its energy from renewable resources by 2020.

But algae fuel is not just useful for the Navy's ships.

This past summer Solazyme also delivered 1,500 gallons of algae-based jet fuel to the U.S. Navy for testing. If testing goes well, Solazyme's algae-based advance biofuel could be powering some of our nation's military aircraft.

A malware-laden flash drive inserted in a laptop at a U.S. military base in the Middle East in 2008 led to the "most significant breach of" the nation's military computers ever, according to a new magazine article by a top defense official.

The malware uploaded itself to the U.S. Central Command network and spread undetected on classified and unclassified computers creating a "digital beachhead, from which data could be transferred to servers under foreign control," William J. Lynn III, U.S. deputy secretary of defense, wrote in his essay in the September/October … Read more

PORTSMOUTH, R.I.--As someone interested in the cutting edge, one of the best things about Road Trip 2010 has been getting a rare look at the U.S. Navy's next-generation aircraft carrier and the world's most advanced submarine.

But that wasn't enough for me. I also had to see where the Navy is going with destroyers, and that's why my visit to Raytheon's Seapower Capability Center here was such a good investment of time: I got a chance for a lengthy discussion on the next-generation, Zumwalt-class guided-missile destroyer, which the Navy expects to be … Read more
