Catalyst: Kaggle

8:00pm – Thursday, August 18 on ABC1

Some scientists come home from their everyday jobs, have dinner with their families and then get stuck into solving the world’s problems before bedtime. They use a Melbourne start up company, Kaggle, to network online and collaborate with experts from related fields. At their disposal are data made available by organisations looking for solutions to problems as far reaching as viral behaviour of HIV; who will win the Eurovision song contest; road traffic forecasting; and hospital resource requirements. Tanya Ha discovers that in addition to the satisfaction of solving big problems, there is significant prize money on offer.

In terrestrial mammals both sides of the brain sleep at the same. Fur seals, however, have developed both forms of sleeping, one for the water and one for land.

Richard Costin Profile The marine environment off the Kimberley coast in Western Australia is one of the world’s most pristine wilderness regions. It’s also one of the least researched. Most of the knowledge about this region comes from passionate naturalists like Richard Costin, who has spent the last 30 years filming and studying his local environment.
