The Wildscreen festival is the world’s biggest celebration of screen-based natural history storytelling which takes place every two years in Bristol. Here: “Walrus in Midnight Sun”. Walrus feed mostly on bivalves in productive, shallow and often sandy habitats in the Arctic. This individual, though, arrived on a beach outside Tromsø, northern Norway, and found comfort on a stranded dead sperm whale. After two weeks he approached Audun, and only half a metre away he stretched his tusk forward and touched his hand gently. “This was one of the most memorable moments of my life”, Rikardsen says. He named the 500kg male Buddy. After two months, the dead whale was decomposed and Buddy suddenly disappeared. (Photo by Audun Rikardsen/Wildscreen 2016)

Breath of an Arctic fox by Marco Gaiotti, Italy. Marco was watching this little Arctic fox as it incessantly called another nearby. Gradually he noticed the fox’s wet breath was quickly freezing in the air after each call. It was late winter in Spitsbergen, Svalbard, and the air was -35C (-31F). Photographing Arctic foxes is often frustrating, as they are normally running around fast in search of food, but this one was very relaxed and let Marco get close enough to focus on it, with the light glowing perfectly in the background.

“Environmental Migrants: The Last Illusion” by photographer Alessandro Grassani, documents the life of people in Kenya, Mongolia and Bangladesh who migrate to escape environmental stresses to the city of their own countries in hopes for a better life. Here: Asia, Mongolia, March 27, 2011. A view of Ulaan Baator over the shoulder of a slumbering drunk. Alcoholism is a huge problem in the city, home to almost half of Mongolia's people. The capital's population has doubled in the past two years. High levels of unemployment and poverty await herders who abandon rural areas and arrive in the city, illiterate and untrained in any skills necessary for urban jobs. (Photo by Alessandro Grassani)

“Most recently, the bushy beard’s masculinity has been turned off and instead adorned with flower power. A wacky new trend sees hipsters weave foliage into their facial hair. It’s emerging across boho America. Yes, men in Brooklyn, Portland and San Francisco are adorning their faces with blossoms, seemingly for the sole purpose of artistic portraits that have been taking over the social media with the hashtag #flowerbeards. It started gaining popularity on the social platform of Tumblr, when a blogger began “Will It Beard” project, and has since blossomed elsewhere around the Internet”. – Linda Sharkey via The Independent.

SpaceX, the space transportation company built from scratch by visionary billionaire Elon Musk, has the grand goal of space travel evolution through the use of re-usable rockets. Its technology – which has proven its worth several times – can reduce the costs of space transportation to its fraction, making it a more affordable way of reaching orbit or traveling beyond.

Christopher Wheeldon’s Alice’s Adventures in Wonderland is the biggest production the Australian Ballet has ever undertaken and it’s also one of the most spectacular. Created for the Royal Ballet and designed by Bob Crowley, it involves puppetry, optical illusions, major setpieces and immersive projections, as well as costumes that some dancers have to actually climb into. Here: Ako Kondo as Alice, on stage September 11, 2017 in Melbourne, Australia. (Photo by Jeff Busby/The Guardian)

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.
