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”.

Cheng Liping, whose husband Ju was onboard Malaysia Airlines Flight MH370 which disappeared on March 8, 2014, shows a picture of she and her husband together and an old card with a message given by her husband, at a park near her house where she and her husband used to visit during an interview with Reuters in Beijing July 24, 2014. Cheng said her life has been totally changed since the incident. Their two little sons, who don't know about this incident, keep asking her when their dad is coming back. Six months after Malaysia Airlines Flight MH370, with 239 mostly Chinese people on board, disappeared about an hour into a routine journey from Kuala Lumpur to Beijing March 8, loved ones of missing passengers derive what comfort they can from what's left behind after the world's greatest aviation mystery. More than two dozen countries have been involved in the air, sea and underwater search for the Boeing 777 but months of sorties failed to turn up any trace – even after narrowing the search area to the southern Indian Ocean – long after batteries on the black box voice and data recorders had gone flat.

An employee in a bookshop adjusts packaged cigarettes which have to be sold in identical olive-brown packets bearing the same typeface and largely covered with graphic health warnings, with the same style of writing so the only identifier of a brand will be the name on the packet, in Sydney on December 1, 2012. A new world-first law forcing tobacco companies to sell cigarettes in identical packets came into effect Saturday in Australia in an effort to strip any glamour from smoking and prevent young people from taking up the habit.
