An injured fan is helped by a riot policeman during clashes between Red Star Belgrade and Partizan Belgrade fans in the stadium before the teams' Serbian Superliga soccer match in Belgrade, April 25, 2015. Serbian league leaders Partizan Belgrade held champions and bitter city foes Red Star to a 0-0 draw in a derby match marred by bad crowd trouble before kickoff on Saturday. The start was delayed for 45 minutes after home Red Star supporters pelted riot police with seats and flares, forcing officers to retreat from the north tier that houses the club's diehard fans.

An adorable baby koala is seen enjoying a snooze after a traumatic start to life. The baby koala, nicknamed “Blondie Bumstead”, is being cared for by a volunteer from the Ipswich Koala protection society in Queensland after her mother was killed by a dog. Blondie, who was named for her light fur, was given just a 50-50 chance of pulling through after the attack. But after a course of antibiotics and some tender loving car from volunteer Marilyn Spletter she has now been given a clean bill of health. According to Marilyn she has hand-reared around 40 baby koalas but says that Blondie, who will be released back into the wild after 15 months, is one of her favourites. She said: “She's got a little character all of her own and she knows what she wants and what she doesn't. When she's stressed I kiss her on the nose or I rub my nose on hers and it relaxes her”.

For our latest mission, we put a Carnegie Hall orchestra in the middle of New York City and placed an empty podium in front of the musicians with a sign that read, “Conduct Us.” Random New Yorkers who accepted the challenge were given the opportunity to conduct this world-class orchestra. The orchestra responded to the conductors, altering their tempo and performance accordingly. This project was a collaboration with Carnegie Hall and Ensemble ACJW.
