Li-Fi is a wireless technology that transmits high-speed data using visible light communication and will be available in the coming months. With scientists achieving speeds of 224 gigabits per second in the lab using Li-Fi earlier this year (that's equivalent to 18 movies of 1.5 GB each being downloaded every single second), the potential for this technology to change everything about the way we use the Internet is huge.

Scientists have now taken Li-Fi out of the lab for the first time, trialing it in offices and industrial environments in Tallinn, Estonia, reporting that they can achieve data transmission at 1 GB per second - that's 100 times faster than current average Wi-Fi speeds.

The technology uses Visible Light Communication, a medium ...

No, we're not referring to the candy. Humanity has done great!

Here's a more intricate version of the poster above. It was created by professor Peter Alway and was published in the book Rockets of the World:

A pigeon can accelerate from a standstill to 60 mph in less than two seconds - that’s faster than a Ferrari

During this experiment, spiders were exposed to a variety of drugs to help determine their effect on the brain.

Spiders who had been given marijuana started out well enough, but were unable to maintain focus.

Benzedrine (speed) produced spiders who spun enthusiastically, though no great thought or care was put into the web design.

Caffeine, one of the most common stimulants taken by humans, produced an erratic web.

Chloral hydrate, an ingredient in sleeping pills, made the spiders doze off after barely getting started on the web.

Though this 1995 experiment sought to determine toxicity of drugs, it was a continuation of experimentation of spiders on drugs that had started in 1948 by P. N. Witt. ...
