00:46 The frozen root of Pluto’s polygonal patterns
In 2015, NASA’s New Horizons probe sent back some intriguing images of Pluto. Huge polygonal patterns could be seen on the surface of a nitrogen-ice ice filled basin known as Sputnik Planitia. This week, a team put forward a new theory to explain these perplexing patterns.

09:06 How the mixed-race ‘mestizo’ myth has fostered discrimination
The term 'mestizo' emerged during the colonial period in Latin America to describe a blend of ethnicities – especially between Indigenous peoples and the Spanish colonizers. But this label is a social construct not a well-defined scientific category. Now researchers are challenging the mestizo myth, which they say is harmful and has a troubling influence on science.
