Tetraploid genetics complicate breeding

00:40 What a trove of potato genomes reveals about the humble spud

Researchers have created a ‘pangenome’ containing the genomes of multiple potato types, something they believe can help make it easier to breed and sequence new varieties. The potato’s complicated genetics has made it difficult to sequence the plant’s genome, but improvements in technology have allowed the team to combine sequences, allowing them to look for subtle differences in between varieties.

10:28 Hundreds of physicists on a remote island: we visit the ultimate quantum party

According to legend, physicist Werner Heisenberg formulated the mathematics behind quantum mechanics in 1925 while on a restorative trip to the remote North Sea island of Heligoland.

To celebrate the centenary of this event, several hundred researchers have descended on the island to take part in a conference on all things quantum physics. Nature reporter Lizzie Gibney was also in attendance, and joined us to give an inside track on the meeting.

23:03 These malaria drugs treat the mosquitoes — not the people

Researchers have developed two compounds that can kill malaria-causing parasites within mosquitoes, an approach they hope could help reduce transmission of the disease. The team showed that these compounds can be embedded into the plastics used to make bed nets, providing an alternative to insecticide-based malaria-control measures, which are losing efficacy in the face of increased resistance.
