I lost a friend to sepsis a few years back By time they recognized it, it was too late. By one account as many as 750,000 people a year are afflicted in the US alone. What's good for the battlefield is good at home as well.
Good to see this technology being developed. A relatively young and healthy friend of mine contracted sepsis and was hours away from death before it was finally identified and before the drugs took effect. It was very scary. I hope that the cost of the device is also reasonable so that this equipment can be purchased by many hospitals.
This looks like a great idea and the latest in battlefield medicine, which has a long history of innovations in emergency surgery and certain preventive techniques. I wouldn't be surprised if DARPA-funded research has shrunk the size of these machines dramatically from what's used for dialysis.
This is exciting stuff. When I was in college, I worked on a portable membrane filtration system for red blood cells. For long-term storage, red blood cells are treated with glycerol and frozen, but the glycerol needs to be removed before they can be used in a transfusion. The system we designed was a closed-loop system which used refractive index and UV spectrophotometry to ensure that the blood cells were clean. This DARPA project is obviously much more complex.
Besides being used to treat wounded soldiers, I could imagine this technology being used to treat maternal sepsis and neonatal sepsis, which claim the lives of many mothers and their newborn children, especially in developing countries.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
