Underwater Wi-fi

Summary: Although I cannot think of the last time I was scuba-diving and had a burning desire to check my email, I am excited for the prospect of underwater internet. The intended purpose is not for watching "Finding Nemo" with the fish, but for detecting tsunamis. While normal wi-fi using radios waves, due to the limited range and stability in water, sound waves will be used instead. This technology has been in use before but it was cumbersome to share data between research teams. The University of Buffalo team is hoping that this will create a shared standard so that anyone with a computer or smartphone could be instantly alerted when a tsunami is approaching.

Space Internet!

Summary: Internet has become a crucial part of life, especially when it comes to communicating over extremely long distances. But our beloved Internet has been lacking in space. Don't fret though, you future astronauts! NASA and ESA have been working on creating an interplanetary net. While they probably aren't too concerned about whether you will be able to watch YouTube or not, it will allow them better control over their rovers.
The way it is now, each robot is controlled separately and if there is an error in sending data, it it lost forever. This new space Internet hopes to remedy that. It is in testing phase with astronauts on the ISS successfully controlling a robot in Germany. I honestly do not understand how it works but the BBC explains it well for anyone who knows computers well.
