The American missile defense system, strategically placed all around the globe, has been the centerpiece of the “defensive” capabilities of Washington for years. The system relies on anti-aircraft missiles, supposed to shoot down incoming hostile projectiles. But the emergence of unconventional weaponry –namely the hypersonic missiles– has raised demand for new, equally unconventional defense systems.

Apart from hitting an incoming projectile with an intercepting one, the anti-missile research and development in the US revolved around two main ideas – using lasers and hitting hostile missiles with a kinetic device. The US military-industrial companies have been recycling the two concepts for years, fielding several prototypes that never entered full-scale production.

One of the biggest obstacles to transplanting organs from one person to another is that the immune system of the person getting the new life-saving organ often tries to reject it. The immune cells see the new material as “foreign” and attacks it, sometimes destroying it.

Right now, the only way to prevent that is by using powerful immunosuppressive drugs to keep the patient’s immune system at bay and protect the new organ. It’s effective, but it also comes with some long-term health consequences.

But now researchers at Tel Aviv University in Israel say they may have found a way around that, using the patient’s own stem cells.

You never know how far your #SpaceApps solution will go! Gema knows that first hand. Hear about her project Deep Asteroid, which was a 2016 finalist, and how she used NASA data and the open-source tool Tensor Flow.


When NASA issued a worldwide challenge to help them better track the asteroids and comets that surround Earth, Gema Parreño answered the call. She used #TensorFlow, Google’s machine learning tool, to create a program called Deep Asteroid, which helps identify and track Near Earth Objects.
