00:11:00 For a long time it’s been believed that having some potted plants around the house will help filter out pollutants and toxins. But now the evidence suggests that houseplants do very little or even nothing at all when it comes to cleaning the air.
00:17:56 There’s around 200 billion stars in our galaxy alone, and probably least one planet orbiting each of them. But a new study suggests there could be an additional 50 billion rogue planets, that aren’t orbiting any stars at all.
00:27:17 Our nearest big galactic neighbour, Andromeda, has long been thought to be the much larger and more massive than the Milky Way. Now, new data from the Gaia mission and the Hubble Space Telescope indicates the Milky Way could be significantly bigger than we thought.
00:39:48 A new study published in the journal Science finds that before agriculture, when humans were nomadic hunter gatherers, languages didn’t have the same sounds that they do now – in fact some sounds just weren’t even possible.

Sean M. Elliott is a science educator, communicator and performer with a new show starting this weekend at the Melbourne International Comedy Festival, Tesla: Death Rays & Elephants!
