According to an article on Fortune magazine published on November 13^th 2014 and few other resources on the internet (refer to references section for more information on the resources), following are the updates on few most ambitious projects of Google X:

1. Project Self- Driving Car: This is one of the most amazing project which Google X is working on. The cars are programmed in such a way that, they can even handle the worst situations on roads. Cars are equipped with sensors and software for sensing objects and driving safely. Objects like pedestrians, cyclists, vehicles etc., are detected by the sensors based on their shape, size and movement pattern. The software can predict the next action taken by all the surrounding objects and chooses a safe speed and trajectory for the car. Currently, this car is self-driven over 1 million miles and are looking for feedback from the community for further improvements.

2. High – Tech Balloons: Project Loon is Google’s idea to provide internet connectivity to remote and rural areas. Connectivity is not interrupted even after disasters. These balloons are present in the stratosphere layer. Cellular spectrum is shared by partnering with telecommunications companies and now people are able to connect to the balloon directly. This project was first tested by Poject Loon pioneers in New Zealand followed by California’s Central Valley and Northeast Brazil for enhancing this technology.

3. Nanoparticles: This project aims at monitoring state of health from inside either by injecting magnetic nanoparticles or by creating a capsule of magnetic particles which after consumption circulated through the bloodstream. Any suspicious proteins, sugars etc., will be binded to these magnetic nanoparticles and a magnetically-active wristband will receive signals.

4. Robots: This project is a collaborative effort of Google and Johnson & Johnson’s Ethicon subsidiary. They aim at creating robotic surgery systems where the doctors will use a console for looking at a high definition image which is by show by robot’s camera. Doctors operate these robotic surgery systems using hand controls. Few operations need levels of precision which is where these robotic systems perform effectively. This will help in creating smaller scars and reduce bleeding.
