Netherlands taxes barnacle geese’s immune system

Dutch scientists have suggested an explanation for why Dutch barnacle geese have a less active immune system once they’ve migrated to Spitsbergen, Norway than when they winter in the Netherlands. “The birds on Spitsbergen appear to invest much less energy in their immune systems, particularly general resistance to disease. Researchers suspect that this might be because there are far fewer pathogens [like bird flu] in the North than here in the Netherlands.”

With their immune systems taxed less, the geese have more energy available to reproduce and change feathers, which the Dutch birds don’t. This means that the geese appear able to adjust their immune systems according to the risk of catching a disease.

Filed under: Film,Online,Photography by Orangemaster @ 12:35 pm

Photojournalist Kadir van Lohuizen has won many prizes for his work and is well known for his project Diamond Matters, about the diamond industry. This time, over the course of a year, Lohuizen investigated the roots of migration in the Americas, a time-old phenomenon that is increasingly portrayed as a new threat to the Western world.

Via PanAm engages the audience through a variety of platforms, using both traditional and new media. The stories made on the road are edited into weekly radio broadcasts, biweekly newspaper columns and regular magazine publications. The Via PanAm website and iApp not only provide contextual background info, but also directly connect readers and viewers with the journey’s progress. Day by day, the Americas and their people reveal themselves to the photographer and his followers as photo-stories, video and audio are uploaded on a regular basis.
