China are hosting the 14th FINA World Championships in Shanghai. In my mind’s eye, aquatics is a sport of power, grace, balance and beauty but our pictures seem to add the additional factors of concentration, determination or maybe sheer fear. Against my better judgement, I just have to mention that some of the expressions on the athletes’ faces remind me of the age old tradition of gurning. What also made an impression are the angles, different points of focus and continually new shapes that compliment a file that could have been very repetitive.

Tsunami-like flash floods raced towards Australia’s third-largest city of Brisbane on Tuesday, prompting evacuations of its outskirts, flood warnings for the financial district and predictions that  the death toll is likely to climb.     REUTERS/Tomas Guerin
