Labour launched their manifesto this week, introducing new rates of tax for high earners. But did the BBC do a good job of explaining it? A screen grab taken from a TV item was spread on social media which gave a misleading impression of the amount of tax you would pay if you earned £80,000 or £123,000. We take a look at what the tax rate would mean for people earning these amounts or more.

When we lie and tell the truth online

Researchers are very excited about the amount of data that is being generated by people using social media and internet tools. But what can we really glean from that information. Seth Stephens-Davidowitz has written a book called Everybody Lies where he explores the image we portray on social media versus the truths we tell about ourselves by what we search online. We also find out some speed dating tips.

Recently BBC 4 aired a documentary from 2007 which made the claim that by 2013 all the sea ice in the world would have disappeared during summer due to global warming. It is 2017 and that has not happened. We find out why that prediction was wrong and what is really happening to sea ice.
