It probably happens every minute of the day: A little girl demands to see the photo her parent has just taken of her. Today, thanks to smartphones and other digital cameras, we can see snapshots immediately, whether we want to or not.

But in 1944 when 3-year-old Jennifer Land asked to see the family vacation photo that her dad had just taken, the technology didn’t exist.

Across the North Atlantic, shipwrecks scatter the seabed like the carcasses of prehistoric creatures. Bygone relics of sea exploration, trade, migration and conflict, these historical monuments are important sites of cultural interest. But they also form the basis of a burgeoning recreational dive tourism industry, and contribute substantially to the biodiversity and abundance of marine life.

The dancer, actress, director and photographer Helene “Leni” Riefenstahl, who died in 2003, is a controversial character, largely because of the many propaganda movies she produced for the Nazis. So when it was recently announced that her estate would be handed over to a Berlin photography museum, historians of the period hoped to find some clarification about the extent of her involvement with the Nazi regime.

Cancer has always been thought of as something that grows rapidly and uncontrollably, but this view may be wrong.

These include downloadable apps (1300 at the last count), books to read or color in, and online courses. Mindfulness practice and training is now part of a global wellness industry worth trillions of dollars.
