Great Moments In Science

Books, new and old, have a particular smell but what we call that 'new book smell' isn't always the same from book to book and even publisher to publisher as Dr Karl Kruszelnicki explains.

When the ancients looked to the stars and wondered if they were alone, they probably never imagined the possibility that Saturn's tiny moon Enceladus might host a strange underwater ecosystem, as Dr Karl Kruszelnicki explains.

This year's Nobel Prizes saw scientists recognised for their work on unusual states of matter and the world's smallest machines. Dr Karl Kruszelnicki explains the science behind the discoveries.

The 2016 Nobel Prize in Medicine or Physiology was awarded for research into autophagy. The word literally means 'self-eating', and it refers to the phenomenon that happens inside cells where 'things' are broken down.

Are you a perfectionist, a crisis maker, a defier or a dreamer?Dr Karl Kruszelnicki discovers the four kinds of personalities that are especially prone to being chronically late—and what might help to change these habits.

In our complex world, the cure can sometimes be as bad as the original problem. For example, you would think that if you had a fire in a data centre, it would make sense to deprive the fire of oxygen by flooding the room with an inert gas. But what if the noise of the escaping gas is loud enough to kill the spinning hard drives—potentially causing more damage than the fire?
