A review article has presented 10 key scientific reasons why the virus that causes COVID-19 is predominantly spread though the air. The research adds to a growing chorus of experts saying the evidence for airborne transmission is “overwhelming”.
-
A new internet speed record has been clocked at an incredible 178 terabits per second (Tb/s) – fast enough to download the entire Netflix library in under a second. It's achieved by modulating light in new ways before beaming it down optical fibers.
-
Researchers have developed a new method for transmitting data to smartphones – by embedding it in music. That means phones might one day receive Wi-Fi passwords or local information via tunes floating through the airwaves, with no perceptible change to the audio as far as the human ear can tell.

Toyota has unveiled new engines based on its Toyota New Global Architecture (TNGA), to be used in both standard gasoline and hybrid vehicles. The company says that the recently-developed, more efficient engines will begin rolling out in 2017.
-
Using a technique known as Probabilistic Constellation Shaping, Alcatel-Lucent and Nokia Bell Labs researchers claim to have achieved subsea optical fiber transmission speeds equivalent to streaming more than 10 million HDTV channels simultaneously across a single cable.
