It’s long been asserted that dolphins and whales are very intelligent. That’s because this group of aquatic mammals, cetaceans, have large brains and because some of their behaviours have been interpreted as displaying notable intelligence. Paul Manger unpacks new research that shows that the brains of cetaceans are indeed special – but for different reasons than previously suggested. His findings show that their brains have evolved to prevent losing heat in cold water. Understanding how this survival adaptation works opens the door to designing better conservation efforts in the wake of rising ocean temperatures as a result of climate
change.
The world’s attention recently zeroed in on the Suez Canal, an artificial channel connecting the Mediterranean and Red seas across Egyptian territory. A massive container ship wedged across the canal, blocking all traffic and creating a huge and expensive backlog of trade vessels. The economic benefits of the canal are apparent. What’s been less explored are the technical mishaps and failed ambitions that dogged it in its early years. Lucia Carminati provides insights into the canal’s fascinating beginnings and what it took to cleave this huge waterway through the desert-like region.

The cetacean brain has a specialised thermogenic system that helps the animal's brain to produce enough heat to maintain a functional brain temperature.
