This little bugger, can hover using multiple jets. The idea is, that eventually it may be able to fight off incoming missiles by using kinetic energy alone. Probably, they'll run in front of the missile or something. They are cool!

Here's how a serious topic like the missile defense system can be condensed into 30 seconds of humorous info bulletin!

This was very unexpected...but in defense of the pigeon, there was a warning sign there Hilarious, enjoy!

This is the Skyguard Laser Defense system, which is part of the missile defense system, able to track, and fire upon incoming air threats. In this video clip the Skyguard Laser Defense System is tested by destroying mortars, artillery fire and missiles launched from the ground. The Skyguard Laser Defense system is definitely the future in terms of the missile defense system which America is believed to have up-and-running.

To isolate individual cells of the immune system and study the interaction in order to improve the treatment of cancer. At this will serve the new biosensor prototype developed under the project Cochise (Cell-On-CHIp bioSEnsor), supported by the European Union and coordinated by Roberto Guerrieri, professor of Electronics at the Faculty of Engineering, University of Bologna . The biological approach used to treat cancer patients consisting of interferon, interleukin-2 or other factors stimulating the growth of different cell types and able to reinforce the natural defenses of the body. But these substances are not always well tolerated. An alternative approach is to identify the immune cells able to fight cancer, cultivate them in vitro and then re-introduce them in the body. But here the problem lies in identifying and in isolating the small number of cells that are selectively able to fight cancer. The objective of the project Cochise (which is intended to last three years), is to develop a new class of biosensors capable of isolating cells (not more than 1 in 10 thousand) that are actually effective in fighting cancer cells . As the first objective was developed a prototype, used to demonstrate the possibility of controlling the flow of two individual cells and putting them in a display where you can study the interaction.

In the blood of alligators and crocodiles proteins were discovered with high antibacterial and antifungal activity. Unlike men, alligators can combat fungi, viruses and bacteria without the body being previously subjected to these micro-organisms. The researchers have demonstrated the McNeese State University and Louisiana State University who collected the blood from alligators and analyzed the white blood cells, which are the cells appointed to immune defense.

A study conducted by an Italian and published on Pnas shows that healthy cells, if required to "diet", have an increased resistance to stress caused by the drugs compared with those ill. Fasting can be a weapon against the heavy effects of chemotherapy. Just as the fight against cancer concentrates its efforts on the so-called magic bullets, drugs capable of selectively target diseased cells from laboratories of the University of Southern California shows a new paradigm: protect healthy cells and then go furiously only against those sick . A team led by biologist Italian Valter Longo, which involved the United States laboratories and the hospital Gaslini of Genoa, has discovered a kind of magic screen that healthy cells (as a result of caloric restriction) have as a defense against chemotherapy. The results of the study appeared on Pnas Early Edition (here a link to the video.)
