00:00:58 By looking at astronomical records from 720 BC to AD 2015, researchers have found a small inaccuracy in modern calculations of the Earth’s rotational speed. The Earth’s spin is slowing down slightly slower than we thought.

00:11:44 A small section of a dinosaur’s tail has been found in a piece of amber for sale in a market in Myanmar. The tail is amazingly well preserved – and feathered!

00:17:31 Nuclear fusion – as opposed to our current nuclear reactors, which use nuclear fission – is the ‘holy grail’ of physics research. It could provide near limitless energy, without toxic by-products. Now the Wendelstein 7-X project in Germany appears to be making progress, successfully trapping plasma in a magnetic cage.

00:29:39 A small study at Johns Hopkins University could give cancer patients suffering from depression and anxiety some hope. It suggests that just a single dose of magic mushrooms can improve their mental health for months.
