Sound waves from fin whale songs could help us study Earth s crust

Wildestanimal/Alamy Fin whale songs, one of the loudest animal calls in the ocean, can be used to learn about the structure of Earth’s crust. Václav Kuna at the Institute of Geophysics of the Czech Academy of Sciences in Prague and his colleague John Nábĕlek at Oregon State University thought of the idea while they were recording seismic activity from earthquakes off the coast of Oregon. Advertisement “I was processing the data and found that there were some signals recorded which I didn’t recognise,” says Kuna. The mystery was solved when he realised the stations were recording songs produced by fin whales (

Female giraffes who hang out with friends live longer than loners

Derek Lee Adult female giraffes who spend time with lots of other females live longer than less sociable animals. Monica Bond at the University of Zurich, Switzerland, and her colleagues observed 512 female giraffes over 1500 square kilometres in the Tarangire Ecosystem in northern Tanzania. They surveyed the landscape six times a year between 2012 and 2016 and took photographs of any female giraffes they encountered. Advertisement The team used a piece of software called WildID to identify giraffes from their spot patterns. Each giraffe is born with a unique pattern of spots and these remain unchanged throughout their life, says Bond. The researchers built a giraffe social network – based on similar research studying human ones – to map each female giraffe’s relationships with other females, the strength of these relationships and their average group size.
