As someone who hosts a weekly radio show, I was initially excited at the prospect of hearing my own voice in recording.

Science Tank | RIP Cassini

Posted 2:33pm Sunday 24th September 2017 by Chelle Fitzgerald

A planet named after the Roman god of time, renewal and liberation seems a fitting final resting place for our lovely friend Cassini-Huygens, whose life was spent furthering astronomical knowledge and the liberation of truth from a far-flung part of our small star system in this abyssal ocean of Read more...

Fluoride is Fine and We Can't Believe That Has to Be Said

Posted 1:39pm Sunday 10th September 2017 by Chelle Fitzgerald

Conspiratorial people love to claim that the government adds fluoride to water and toothpaste in some dastardly plan to make us all sleepy slaves, helpless to resist their evil bidding. The truth, however, is far less scandalous and far more reassuring - fluoride is your friend, my friend, and Read more...

A single drop of Russell’s viper venom will turn blood in a cup into a coagulated blob that looks like moulded jelly. However, in a living body, the venom has a different effect.

It was 2010 and my father had passed away earlier that year. My usual logic blinded by grief, I did what any standard mourner would do and booked an appointment to see a medium. Walking into her home-cum-spiritual lair, I immediately noticed the tacky abundance of quartz crystals (when will people Read more...

Science Tank | Supervolcanoes

Posted 2:02pm Sunday 6th August 2017 by Chelle Fitzgerald

It was 75,000 years ago, and all was peaceful in the Sumatran jungle - birds were chirping and swishing through sunlight-dappled tree canopies, while insects chirruped busily on the jungle floor.
