Whale songs reveal existence of new blue whale population

There are different populations of blue whales worldwide, and each can be identified by its own whale songs.

A new population has been identified based on its unique whale song, recorded in three locations: the Arabian Sea coast of Oman, the Chagos Archipelago in the central Indian Ocean, and Madagascar in the southwest Indian Ocean.

This discovery was reported in the journal Endangered Species Research.

Starfish-like fossil holds clues to evolutionary past

A well-preserved fossil dating back 480 million years is being used by researchers at the University of Cambridge to decipher the origins of the modern-day starfish.

Named Cantabrigiaster fezouataensis, the fossil was discovered in Morroco's Anti-Atlas mountain range. Frozen in time for 480 million years, the fossil yields features that are similar to both sea lilies and modern-day starfish.

boot show 2021 cancelled

"The continuing high level of infection and the fact that the end of the lockdown is not foreseeable for the time being make a resumption of trade fair operations at the end of April appear increasingly unrealistic", states Wolfram N. Diener, CEO of Messe Düsseldorf.

"We have reassessed the situation with our partners and jointly decided to cancel boot 2021 early. Our priority is the health and planning security of our exhibitors, visitors and service providers. All activities will now be focused on the successful staging of boot 2022."
