Loudest sound in Earth's history
|
view preview
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.

Miraculous headless chicken
|
view preview
This is Miracle Mike, the Headless Chicken. Beheaded by a farmer for dinner in 1945, part of Mike's brain was accidentally spared, which allowed him to live for another 18 months. In fact, Mike thrived without his head, gaining more than 2 kg as the farmer fed him food and water by depositing it into his exposed oesophagus.

Where else are taste buds found in the body?
|
view preview
Lungs have 'taste buds' which can detect bitter-tasting compounds, although aren't connected to the brain! The taste receptors in the lungs are the same as those in the mouth except they are not found in clusters and do not send any signals to the brain.

Science is true whether you like it or not
|
view preview
Not promoting anyone here, but I do like this quote. The goal of science is to come as close as we can to understanding the cause-effect realities of the natural world. It's never "truth" or "facts". "Truth" and "facts" can mean different things to different people.

This super-effective cancer-fighting berry can help fight cancer
|
view preview
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." ...
