Agar comes from multiple sources, as many red seaweeds are “agarophytes” (that is, seaweeds containing agar in their cell walls). Species of Gelidium are the most important source of bacteriological (lab-grade) agar. Other main agarophytes, largely used for culinary agar, include red seaweeds from the genera Gracilaria, Pterocladia, Ahnfeltia, and others. Species from the genera Eucheuma, Gigartina, and Chondrus have been used as agarophytes in research during agar shortages.9

I’ve been lucky enough to attend six summer Olympic Games, but I’d never before photographed a Winter Olympics. They’ve always been too far away and the UK has never been a major snowsport country, which has limited their news appeal. This time it was different. With Team GB anticipating a record medal haul and the Games staged in northern Italy, I headed off with nervous excitement, lured by the promise of fast action sports occurring amid beautiful snowy vistas. I covered ski jumping, big air, ice hockey, biathlon, curling and much more. A lot of it was alien to me but it was very enjoyable. There were new rules to learn, new challenges to face – I’ve certainly never had to wear sharp crampons at a football match.
