3D Printed guns



A short documentary from VICE about the home based manufacturing of guns through 3D printing processes.

Guns, some will say, are tools and you cannot criticise or regulate the ownership of the tool by the potencial evil use of it. This is quite true in most cases but the reality is guns are tools ment to be use on evil ways, guns are either for killing something or for get control over a subject by threading to kill or injure it.  Criminals do that as well as the Police.

Now with the digital manufacturing revolution getting into every home and supported by 3D files sharing communities we can not only print guns but we also can share with the  world specialised knowledge about building guns, so everyone having a 3D printer can become a potencial gun man to defend his own couse, this being criminal life or a fighting an oppressive ruler.

As with every mayor technological revolution on manufacturing the bottom line quickly becomes about power and dominance either from one country to another or from one side of society to the other, but differently from previous breakthroughs this one place the responsibility to answer the question about how to use this new possibilities directly on the hands of the one used to know as the bystander.

low cost cooling device for neonatal care


When babies are deprived of oxygen before birth, brain damage and disorders such as cerebral palsy can occur. A common cause of this deficiency is knotting of the umbilical cord, and in developing nations, untrained delivery, anemia, and malnutrition during pregnancy can also contribute to oxygen deprivation. Extended cooling can prevent brain injuries, but this treatment is not always available in developing regions where advanced medical care is scare. Johns Hopkins University undergraduates have devised a low-tech $40 unit to provide protective cooling in the absence of equipment that can cost $12,000. The device, called the Cooling Cure, lowers a newborn's temperature by about 6 degrees F for three days - a treatment that has been shown to protect the child from brain damage if administered shortly after a loss of oxygen has occurred. The device, simply made of a clay pot, plastic-lined basket, sand, instant cold pack powder, and a temperature sensor, is powered by two AA batteries.
