Military.com is reporting that the U.S. Army is deploying new body worn sensors in Afghanistan to measure and help understand how intense impacts, such as nearby explosions, affect the human body. Each unit contains four sensors that communicate with one another as well with an armored vehicle based system that has additional sensors that collect information.
The Army hopes that the I-BESS (Integrated Blast Effects Sensor Suite) system, which passively collects and manages the data with minimal maintenance by the soldiers, will help identify those with a greater chance for asymptomatic injuries, often in the brain, and improve armor and other mitigation strategies.
From Military.com:
The Army’s Rapid Equipping Force has worked hard with the Georgia Tech Research Institute to rush the sensor suite to Afghanistan to collect as much data as possible on concussions and TBIs before soldiers leave in 2014.
“We’re trying to get the data while we still can. I don’t want this to sound wrong, but the data we collect from these explosions is very important for us to measure how these blasts affect a soldier’s head and body,†said Amy O’Brien, a REF chief scientist.
The Army is also installing 42 vehicles with floor-and seat-mounted accelerometers to measure the effect of blasts on soldiers inside vehicles hit by improvised explosive devices. Engineers will install I-BESS sensors into Mine Resistant Ambush Protected All Terrain Vehicles and MaxxPro Dash MRAPs in Afghanistan rather than ship more vehicles.
All of the data collected by the I-BESS will go to the Joint Trauma Analysis and Prevention of Injury in Combat, where medical professionals will have access to the database. A personal code inside each soldier’s Common Access Card will protect the soldier’s individual medical data, Hester said.

Question by Vicki M: What will you do to revise the "free trade" agreements that have devastated American workers? As Ross Perot predicted, free trade agreements have done nothing for us but "suck jobs out of America". Many AMERICAN companies now produce products to sell to here outside of the US. This is un-American and must be accounted for either in tariffs or taxes. Also, these supposedly "free trade" agreements are not truly free, these other countries have many restrictions on imported products. Without these changes, our economy may never recover because we need JOBS. Best answer for What will you do to revise the "free trade" agreements that have devastated American workers?:
Answer by Vulcan Hold public hearings on it - a LOT of public hearings where actual people (not just Billionaires) can be heard.
Answer by STEVEN True "Free" trade has been undermined by Congressmen and Cabinet members who get BIG campaign contributions and kick-backs from large corporations. Unions and their heavy handed requirements have also forced companies outside the US, as have DEQ/FDA and other regulatory commissions.
Answer by Willis Money talks, BIG money talks louder, Lack of character listens and will do NOTHING.
Answer by thinkbeforeuspeak Free trade is primarily between the US, Canada, and Mexico. Given that Canada is our largest trading partner (other than China), and provides us with most of our oil, the free trade agreement is of huge value to our economy and many people benefit as a result. Not to mention, Capitalism is a multi-national phenomenon. Outsourcing is part of capitalism. To prevent corporations from going where labor is cheapest is to interfere with an important part of the market. If American's want to keep the jobs here, they'll have to be willing to work at sweat-shop wages. So rather than letting others work cheaply and benefit off of the resulting low prices, you'd prefer that we get those jobs back by either throwing Americans in sweatshops here and abolishing the minimum wage, or forcing Americans to pay 100x as much for those goods by forcing companies to produce them here for 100x the cost.

Curiosity Lands on Mars: Know What You're Watching When You're Watching '7 Minutes of Terror' [science-oneinfo.blogspot.com]
Question by unstopabel45: What does the following mean? Distinguish the different senses of "science" in different disciplines of scienc? I have to write a final paper for my philosophy class: Philosophical theories of knowledge and reality I do not understand what my professor is asking for me to explain in this paper. The topic is summarized in the statement above. Actual statement:::: Make a long list of different kinds of science--Library science, Domestic science, and the more familiar sciences. Distinguish the different senses of "science" in these different disciplines. Please explain what the professor means and any examples would be nice. Thank you very much. Best answer for What does the following mean? Distinguish the different senses of "science" in different disciplines of scienc?:
Answer by Alan Turing He is just trying to get you to realize that people are somewhat sloppy in their use of the word science. With things like library science that science simply means some means of organizing and categorizing things. Biology science was like that until Darwin's core theory of evolution change it into a science that is about explaining why things are the way they are and how they got there. Before Darwin, biology was just a sort of library science of categorizing and grouping of living things. Physics and chemistry are sciences in the way the term science is most accurately used. They are not just a means of categorizing and grouping things, and not just a way of explaining how things got to where they are, they are also a methodology of predicting what will happen in the future given known conditions. Domestic science, political science, and sociology and psychology are also sciences but again the emphasis shifts to issues of control, defining what is normal or standard, how to effectively make change or maintain the status quo, and so forth. So in each of these science means something that can be radically different and you need to be aware of it to understand what a science is. And your study could be called a science of sciences. And that is part of what philosophy is.

A cheat-sheet guide to the dramatic descent of the Little Rover That Could
NASA
Later today, at 10:30 p.m. West Coast time, NASA's Curiosity rover is scheduled to touch down on the surface of Mars. If it's successful, the landing will represent not just a step forward for Martian exploration; it will also represent progress for interplanetary navigation.Â
But ... if it's successful. People are calling Curiosity's impending landing "seven minutes of terror" for a reason: Though there are many reasons to hope that the landing will go smoothly -- more than 2.5 billion reasons, in fact -- there is also much potential for the touch-down to go spectacularly wrong.
Here's a guide to Curiosity's trip as it's gone so far and as it's expected (and hoped) to conclude.
What is Curiosity, exactly?
The rover is basically a really expensive, and really advanced, robotic photographer. Curiosity -- full name: The Mars Science Laboratory -- is, as our Ross Andersen has put it, "a dune buggy equipped with a set of tools and instruments to shame Inspector Gadget." It carries ten instruments in total, among them two rectangular "eyes" -- the first a primary imaging camera featuring different filters and focal lengths, and the second a large, circular camera that can fire a laser that turns rock into vapor. (Another camera on the rover picks up the images from the laser-firer and interprets their composition.)
So "this rover can go around firing laser beams at rocks and other materials to find out what they're made of; I'd say that's one of its most impressive instruments," planetary scientist Michael Mischna told Andersen. And the rover can also gauge Martian weather. It can film in HD. And in 360-degree panoramas.
What does it look like?Â
Curiosity, our latest emissary to the Red Planet, is slightly larger than a standard automobile: It measures ten feet long by seven feet tall at the top of its mast. That makes it substantially larger than NASA's previous Mars explorers, which have ranged in size from slightly-larger-than-a-Roomba to slightly-smaller-than-a-human. And Curiosity really does look like a dune buggy. Here's one picture:Â
NASA
So, all things considered, Curiosity is actually pretty small! How has that tiny little thing gotten to Mars?Â
Curiosity has been hitched to an interplanetary spacecraft, tucked inside a protective aeroshell for the duration of the voyage to Mars. It's been traveling, ensconced in that way, for eight-and-a-half months -- and for 345 million miles.
Here it is, being launched into space by the Atlas V rocket, on November 26, 2011:Â
NASA
So now that it's approaching Mars, how will Curiosity descend to the Martian surface?Â
This is the nail-biting part. Curiosity's approach phase will begin 45 minutes before the spacecraft penetrates the Martian atmosphere. To help with navigation, Curiosity will enter that atmosphere 2,188 miles above the center of the planet. It will then barrel into Mars's atmosphere at 13,200 miles an hour, finally making entry "in a burst of fire."
The aeroshell that has protected Curiosity in its voyage to Mars -- at 14.8 feet across, the largest ever used for a Martian mission -- will at that point act as a heat shield as the craft makes that entry.Â
NASA
Then begins the descent and landing (EDL) phase -- the true test of Curiosity's mettle. That phase begins when the craft reaches the atmosphere of Mars, roughly 81 miles above its landing site, and ends when the rover -- fingers crossed! -- touches down on Mars intact. This is the "seven minutes of terror" everyone's been talking about: During those tense minutes, the spacecraft carrying Curiosity -- powered by rockets -- will decelerate from its starting velocity (that mind-boggling 13,200 miles an hour at the top of the atmosphere) to a stationary state. The margin of error here is zero: If the craft doesn't decelerate enough, it will hurl into the Martian surface; if it decelerates too much, it'll lose momentum and crash.
And how, actually, will it land?Â
Right. As the spacecraft is descending, its heat shield will be jettisoned and its backshell will drop away, allowing the craft's built-in radar system to determine its altitude and velocity. That system will leverage the friction of the Martian atmosphere to slow the spacecraft and trigger the craft's robotic steering.
And "that's one of the unique things about this mission -- the capsule isn't just a ballistic object plummeting through space," Mischna told Andersen. "It actually moves in response to precise conditions in the atmosphere."
To help ensure a gentle landing, The Mars Science Laboratory is making use of the largest parachute ever built for a planetary mission. The device, more than 165 feet in length and more nearly 51 feet across, has 80 suspension lines to keep it secured to its craft. And it's designed to survive the Mach 2.2 punishment it'll take as it hurtles through the Martian atmosphere.
NASA
Part of NASA's challenge here was figuring out how to deal with the (relatively!) large size of Curiosity. "The gravity on Mars is about one-third of the gravity we have here on Earth, which means you don't need as much rocket power to make the spacecraft hover -- but it's still a lot of power," Mischna said. "To get something of this size to the Martian surface, you have to come up with a whole new landing system because the air bags, which we used on previous rovers, just aren't going to work. It would be like dropping a piano wrapped in bubble wrap and expecting it to land without damage. We had to completely rethink our approach to landing, but that's a good thing, because we hope this will be the first of many projects like it, eventually leading to human exploration on Mars. And if you're going to send humans to Mars, you're going to need to bring a lot of heavy equipment -- places to live, food, water, etc."
If you want a first-person sense of the intricacies involved in the landing, there's a (free) Xbox game you can play to give yourself an idea.
Where, specifically, will Curiosity land?Â
The rover is scheduled to make Marsfall at the Gale Crater, an impact crater that measures over 95 miles in diameter. (That would make it nearly as wide as Earth's Chicxulub crater, the impact zone of the asteroid thought to have killed the dinosaurs.) The Gale Crater was formed between 3.5 and 3.8 billion years ago. And it was chosen as Curiosity's destination because scientists believe that the sediment in the crater is likely to contain evidence that there was once a habitable environment on Mars.Â
Mt. Sharp, in particular -- the official name of which is Aeolis Mons, and which forms the central mound of the Gale Crater -- features an enticing series of layered rock deposits. Those layers could offer scientists a rich source of data about the Martian surface, which is also to say the Martian environment, as it's changed over time.
And there are lots of layers to explore. Mt. Sharp is comparable in height to some of the tallest mountains on Earth:
NASA
And yet the Gale Crater was actually controversial as a landing site, Wired notes. Despite Mt. Sharp's promising layers, some engineers dismissed the site as too risky for a landing. Enhanced navigational procedures, however, made NASA determine that the potential reward offered by the site would be worth the landing's considerable risk.
How will Curiosity actually get free of the spacecraft that's carried it to Mars?
Curiosity, as Mischna noted, is too big to rely on airbags to soften its landing. Instead, the spacecraft itself will use a sky crane to connect the rover to the Martian surface. The method relies on a system of steerable rockets, located on the underbelly of the spacecraft, that will both slow the vehicle and mitigate the effects of any horizontal winds it might encounter. Once the craft has slowed to zero velocity, the sky crane system will lower Curiosity on a bridle that will extend about 25 feet to the ground. (Curiosity will actually, at first, be attached to its craft via three nylon -- nylon! -- tethers, along with an "umbilical cord" to provide power and a communication connection.)
The craft's landing system will place the rover on its wheels, allowing mission controllers to check its systems and make sure that it survived the landing intact and ready to roll. As soon as touchdown is detected, though, the bridle will be cut using pyrotechnic cutters -- and the craft itself will launch away from Curiosity's landfall site, crash-landing at a safe distance from the rover.
NASA
Will the landing really be as dramatic as everyone is saying?
Yes. Mostly because there are so many ways that it could go wrong, and so many aspects of Curiosity's fate, at this point, that are out of human control. Curiosity's planned Martian descent is "the most daring landing ever attempted on an alien world," as The Guardian put it, because the descent itself is alien to us. All we can do, at this point, is watch.
Speaking of ... can I watch the landing?Â
You can! Right here. Or here. Or here. (And you can also get updates from the perky little rover itself via -- natch -- its perky little Twitter feed.)
Whatever you see, though, won't be happening in real time: For this mission, there's a 14-minute communications gap between Earth and Mars, meaning that even the scientists who created Curiosity will be spectators in the landing itself. The landing's success, or failure, will be determined by the interaction between earthly computers and Mars's gravitational pull. And while the landing itself is scheduled to occur at 1:30 a.m. Eastern, officials have cautioned that confirmation of the touchdown could take several hours -- or even several days. During which time, we'll just have to wait. And hope.
So what if something goes wrong?
Something could go wrong! And really easily. There are multiple steps that coordinate iteratively over the course of Curiosity's "seven minutes of terror." If any of those doesn't go precisely according to plan, the entire mission will be moot. "Failure could set back American-led Mars explorations for years," The New York Times notes.
Then again, though: If Curiosity fails, it won't be the first time NASA has experienced a setback in its overall mission to Mars. In 1999, infamously, the agency lost a Mars orbiter due to confused measurements between metric and English systems. But NASA has also had great successes with rover exploration of the Red Planet. The rover Opportunity, launched in 2003 and landed on Mars in 2004, is still actively exploring the Red Planet. In 2010, NASA finally lost communication with Opportunity's twin rover, Spirit, which, in 2009 -- after nearly five years of Martian recon -- became stuck in Mars's soft soil. So if something goes wrong with Curiosity, "we'll pick ourselves up, dust ourselves off," Doug McCuistion, NASA's Mars exploration program director, told reporters at a news conference on Saturday. "This will not be the end."
What's Curiosity going to do once it's landed?Â
The rover will ascend up Mt. Sharp, probing its layers for data suggesting that Mars once supported life. "We're looking for habitability, not specifically for life, but for the conditions where life might have thrived," UK Space Agency research fellow Matthew Balme told the Daily Telegraph. He added: "We want to find evidence of standing water." Project scientist John Grotzinger echoes that caveat. "Curiosity is not a life detection mission," he told The Guardian. "We're not actually looking for life; we don't have the ability to detect life if it was there."
And the habitability focus extends, most intriguingly, to humans. NASA will use its Martian soil analysis in part to determine the feasibility of future manned missions to the planet.
How will Curiosity stay energized for its travels?
Curiosity is equipped with two lithium-ion batteries. But its journeys will also be powered by a plutonium-238 fueled electrical generator -- a lump just the size of a marshmallow. And that little lump, actually, makes Curiosity "revolutionary." Because the Little Dune Buggy That Could has, for the first time, a nuclear power source. The decay of the plutonium, Mischna explains, will create heat that will, in turn, generate electricity that will charge the rover's batteries. And that will produce much more power than any of the previous rovers enjoyed. As an additional edge over solar panels, it will also make environmental factors like clouds and dust irrelevant, giving Curiosity a constant stream of energy.
How long will Curiosity spend on Mars?Â
It's scheduled to spend one Martian year, or 687 Earth days, exploring the Red Planet.
Is it just me, or does this whole thing seem like it could double as a plot for a really nerdy but really fantastic action movie?
It is not just you. And this could be that movie's trailer:
