2014: The Year In Science
Lasers in Space- It looks like communication in space is changing from radio waves to lasers.
Mapping the Human Brain- There is a project started in 2013 to map the human brain, and create a simulated brain. I wonder if it will gain self awareness? Please keep in mind this is not PRSI.
Practical Quantum Physics- IMO one of the most impressive breakthroughs which validates the notion of quantum physics for the masses is an encryption system based on the principle that observing something changes it...
Lasers in Space- It looks like communication in space is changing from radio waves to lasers.
In January 2013, the Lunar Reconnaissance Orbiter received a historic transmission: an image of the Mona Lisa. It was the first time scientists used a laser to send data to the moon, a feat that promises to exponentially increase the flow of information to and from space.
For the past 50 years, spacecraft have relied on radio waves to communicate with Earth. But radio has limitations. Airwaves are crowded. Signals degrade with distance, so transmissions require power-hungry generators and large antennas. Focused laser light operates in wavelengths 10,000 times shorter than radio, pumping out more wavesand more informationeach second. Lasers maintain signal strength across large distances, so transmitters require less power. And spacecraft carrying smaller receivers would be cheaper to launch.

On October 7, 2013, at the Swiss Federal Institute of Technology in Lausanne, one of the most ambitious brain-research projects in history officially kicked off. The Human Brain Projectbacked by 1.2 billion euros and more than 250 researchersaims to create the first complete computer simulation of the human brain. Over the course of a decade, everything we know about the organs biology will be modeled. Eventually, virtual neurons will even be subjected to virtual drugs.

Quantum key distribution (QKD) is an essentially unbreakable encryption protocol that exploits one of quantum physics more head-spinning principlesthat simply observing information changes it. In a QKD-based system, a randomly generated key is encoded on light particles and shared through fiber-optic cables before being used to encrypt sensitive data. Any attempt to detect the key en route will alter its photons, indicating that the transmission has been intercepted and a new key is necessary.
So far, QKD has remained tethered to fiber-optic networks. It also requires large emitters and detectors, but now researchers are working to miniaturize them: Nokia and the University of Bristol in England are collaborating on a quantum source small enough to fit in a phone, while physicists at the Institute of Quantum Computing in Waterloo, Ontario, are developing microsatellites that could beam encoded photons across the globe.
