Watch uranium emits radiation inside a cloud chamber. This is a small piece of uranium mineral sitting in a cloud chamber, which means you can see the process of decay and radiation emission.

Perhaps one of my favourite TEDtalks. Amy Cuddy’s research on body language reveals that we can change other people’s perceptions - and even our own body chemistry - simply by changing body positions. Her take-home message is simple, instead of faking it till you make it and living a life as an impostor, you must fake it till you become it.

The KodKod (Leopardus guigna) is the smallest wildcat - it's even smaller than domestic cats. It lives primarily in central and southern Chile and marginally in adjoining areas of Argentina. Check out the video below for more information on this cute creature:

From July 10 to September 30, a team from the US National Oceanographic and Atmospheric Administration’s (NOAA) exploration ship, Okeanos Explorer, is going to be mapping the deep waters of the Hawaiian Archipelago in the North Pacific Ocean. This largely unknown deep-sea ecosystems will be explored for the first time using robotic submersibles, as shown in the video above.

Turkish communities living in the mountains in the north east of the country use a remarkable whistling language to communicate. Around 10,000 people use the bird-like whistle, which researchers suggest is the first known form of language to use both sides of the brain.

Whistlers usually speak Turkish when talking near each other, but switch to whistling when they want to convey a message over longer distances, which can be up to five kilometers. The whistling language has the same vocabulary and grammatical structure as Turkish, it’s just a different format. Scientists have previously assumed that all spoken language, written texts and sign language mainly utilize the left hemisphere, but this doesn't seem to be the case for the whistling l ...

Nitrogen triiodide (NI3) is a contact explosive that sets off whether it comes in contact with a feather or a bug. As shown in the diagram, the chemical is made up of a cluster of three iodine atoms around one side of a nitrogen atom. The result of such a crowd around one atom causes something called bond strain - the atoms repel each other in a small space. The result of this bond strain is that the molecule is prone to falling apart very, causing the mini explosion you see ().

Bdellovibrio bacteriovorus is a bacterium that attacks other bacteria. It can charge its prey at speeds of up to 100 micrometers per second, comparable to a human running 600 kilometers per hour. It then bores into its hapless victim by spinning at 100 revolutions per second. Most bacteria aren't quite that fast, but they can move by whipping flagella or by spiraling through their environment.

This mysterious goo gobbles up everything in its path. It's mesmerizing to watch and a lesson in magnetism.
