Microwave Tissue Soldering »
“A portable microwave generator and hand-held antenna are used to seal wounds, binding the edges of the wound together using a biodegradable protein sealant or “solder”. This method could be used for repairing wounds in emergency settings, by restoring the wound surface to its original strength within minutes. This technique could also be utilized for surgical purposes involving solid visceral organs (i.e., liver, spleen, and kidney) that currently do not respond well to ordinary surgical procedures.
The experimental approach utilized was to produce a “test wound” in bovine muscle using a scalpel. Once the incision or cut was made, different candidate protein solders and varying microwave parameters/frequencies were tested for wound closure efficacy. To date, over 200 tests have been performed. Once sealed, the effectiveness of wound closure was measured using a tensile strength meter. Welds stronger than the uninjured (uncut) muscle have been consistently and precisely achieved.”
El avión segador. Esto es una de las cosas más MACARRAS que he visto en mucho tiempo. Lástima que lo que tiene de macarra lo tenga de inútil. Aun así me hubiera encantado presenciar alguna de sus misiones. Ahora los militares sólo decapitan infectados usando aspas de helicóptero. ¡Menudencias!
The Soviet ‘Fire Hedgehog’
What looks to be an anti-infantry experiment - 88 downward-firing machine guns in the bomb bay of a Tupolev Tu-2, giving a firing rate of about 1,300 rounds per second.
Believed to be flown and tested in 1944, and abandoned due to the problems associated with in-flight reloading of the guns.

Esto era algo que salía en Cyberpunk 2020 (el juego de rol) y que me parecía un poco lo suyo, curarte los agujeros poniéndote una plasta orgánica que se transforme en el tejido adecuado. Están trabajando en ello.
“According to Darpa’s solicitation, 85 percent of recent wartime injuries involved damage to the extremities and facial regions. That often means multiple surgeries, rehab and permanent disability for vets. They’re hoping to eliminate the injuries, and their long-term consequences, with a system that can reproduce in vitro tissues with the same structural and mechanical properties of the real stuff. And maybe make better versions: Darpa wants implanted results that will “replace, restore or improve tissue/organ function.”
Phase II of the project will see animal testing of the most promising systems. And Darpa foresees eventual use by military and civilian populations. Sounds like fodder for Hollywood, but broken bones and third-degree burns might one day be treated with an easy drop-in at the body part bank.”
El artículo de la propia DARPA, aquí. Por cierto, es muy interesante la lista de puntos que supuestamente hacen a DARPA una organización competente. Si la abstraes, vale para montar cualquier empresa.
