Episode notes

Hippos can recognise each other's honking voices, and if they hear a group of hippos they dislike, they react by aggressively spraying dung. Little is known about hippo communication because in the wild the animals are very difficult to tag and identify. Authors say that hippo communication should be taken into account when animals are relocated for conservation purposes. For example, biologists could prepare a settled pod for new neighbours by playing recordings of the incoming animals' voices.

00:53 How virtual meetings can limit creative ideas

In April, we heard how a team investigated whether switching from face-to-face to virtual meetings came at a cost to creativity.

Hippos’ habit of aggressively spraying dung when they hear a stranger, and why being far from humans helps trees live a long life.

18:36 Higgs boson turns ten

Ten years ago, scientists announced that they’d found evidence of the existence of the Higgs boson, a fundamental particle first theorised to exist nearly sixty years earlier. We reminisced about what the discovery meant at the time, and what questions are left to be answered about this mysterious particle.

28:28 The open-science plan to unseat big Pharma and tackle vaccine inequity

In this episode of Coronapod we investigated a radical new collaboration between 15 countries — co-led by the WHO, and modelled on open-science — that aims to create independent vaccine hubs that could supply the global south. This project was supported by the Pulitzer Center.

40:10 Missing foot reveals world’s oldest amputation

In September, we heard about the discovery of a skeleton with an amputated foot, dated to 31,000 years ago. The person whose foot was removed survived the procedure, which the researchers behind the find say shows the ‘surgeon’ must have had detailed knowledge of anatomy.
