It shattered the eardrums of sailors over 50 kilometres away, sent shock waves around the world several times over, and could be heard by 50 geological locations covering over 10% of the globe. This was the loudest sound in recorded history occurred in 1883. The sound was caused by a record-breaking volcanic eruption that sent smoke up almost 80 kilometres into the air as ash fell into the ocean some 20 kilometres away. Burning hot debris was shot from the mouth of Krakatoa's volcano at speeds of up to 2,575 kilometres per hour, which is more than double the speed of sound.

The video below gives you an idea of what an erupting volcano sounds like, but of course, nothing close to what was described above!

Researchers have shown that people who believe they've slept well and "deeply", even when they didn't, perform better on tests than those who're told they slept badly. So simply believing you had a good night's sleep can improve performance.

A drug made from berries produced the blushwood tree (Hylandia dockrillii), found in Australia, has been used to treat animals with face and neck tumours, and it starts taking effect within five minutes. Human trials have now been approved. According to researchers, in 75 percent of the 300 animals cases, the tumour disappeared in individuals that were treated with isolated compound found in the seed, and has so far not come back. "The compound works in three ways essentially: it kills the tumour cells directly, it cuts off the blood supply and it also activates the body's own immune system to clean up the mess that's left behind." ...
