Soap Bubble Structures by Kym Cox. Bubbles optimise space and minimise their surface area for a given volume of air. This phenomenon makes them a useful tool in many areas of research, in particular, materials science and “packing” – how things fit together. Bubble walls drain under gravity, thin at the top, thick at the bottom, which interferes with travelling lightwaves to create bands of colour. Black spots show the wall is too thin for interference colours, indicating the bubble is about to burst. (Photo by Kym Cox/2019 Science Photographer of the Year/RPS)

Jerome Flynn, who played Bronn on “Game of Thrones“, posed in a cage on London's Oxford Street on November 26, 2019 alongside the campaign group Farms Not Factories to raise awareness that most supermarkets and high street food chains are still sourcing their pork almost entirely from factory farms. Says Jerome "Factory Farming is one of the most horrific examples of how far we have strayed from our hearts in the relentless drive for profit and so called progress”.

Will Rosner and a playful humpback whale pose for a selfie. This man is certainly knows how to enjoy life travelling the South Pacific and posing for selfies with a whale. Australian carpenter Will Rosner, 24, from Sydney, Australia, has been travelling the world for the past 18 months but nothing could have prepared him for this incredible postcard moment. Swimming in the pristine waters of the Tonga in the Pacific Ocean Will was lucky enough to have the chance to swim with an entire pod of humpback whales. (Photo by WIll Rosner/Caters News)

Yogis and street performers have been simulating levitation with nifty contraptions forever. They appear to be held aloft via nothing but their preternatural mental prowess. But are really enjoying the benefits of basic physics just like the rest of us when we use a chair. However, just because it’s perfectly explainable doesn’t mean it isn’t nifty. I’m especially impressed by this 2-person version and am still trying to work out how exactly the chair they’re using is shaped at the base.

Jonny Joo, 23, visits derelict malls, stations, towers and other places because they remind him of Silent Hill – a psychological horror video game which was made into a film. “When I first started exploring places, so many would remind me of the game. It was a world I was kind of obsessed with because of how dark and eerie it looked”, Joo said. His book, titled “Empty Spaces”, will feature 116 images and is being released this week.

“That’s the only way to show how we really are” – sweaty, exhausted, but happy, actress and singer Juliette Lewis said about the idea of a photo collection capturing musicians moments after a concert.

Ever wonder what a human head would look like if he or she was turned into a pastry? Well now you can, thanks to the works created by the photographer Brandon Voges. Some of the pictures are light and funny, while others are pretty gruesome and outright disgusting. For example, the comparison of an old lady with some chunky, orange-colored pastry coated with what looks like syrup, really makes you lose your appetite. It is a wonder how they decided to use such an unappealing picture to promote an annual food show of the National Restaurant Association. (Photo by Brandon Voges)

Few people haven’t heard about the ancient city of Persepolis, which lies at the foot of the Mountain of Mercy (Kuh-I-Rahmat). In ancient times, Persepolis was the capital of the Achaemenid Empire. Regretfully, it was burned by the Greeks in 330 BC after they looted the immense treasure of this city. It is said that Greeks needed 5,000 camels and 20,000 mules to carry all the treasures from Persepolis. The only thing of Persepolis that has survived the wear of time is the ginormous stone terrace 530 by 330 meters adorned by elaborate stone sculptures. It is amazing how intricately detailed some of the sculptures are, despite the fact that they were created many centuries ago.
