One of the highlights on the Audi stand is the bicycle technology concept known as the Audi e-bike Wörthersee – a sport bike that does not fit into any of the usual categories. It is neither a pedelec nor a conventional bike, but is best described as a high-end pedelec made by Audi for sport, fun and tricks. The Audi e-bike Wörthersee combines the Audi brand’s principal competences – design, ultra, connect and e-tron – and explores the limits of what is technically feasible in terms of design, lightweight construction, networking and electric mobility.

“Alice in Waterland” is a beautiful series of photographs re-imagining the Lewis Carroll classic underwater. It’s a creation of photographer Elena Kalis, who lives on a small island in The Bahamas, surrounded, she says, “by pristine clear warm water. Underwater is where I spend a lot of time; snorkeling, diving, photographing. It is fascinating how the world changes down below: light, sound, gravity and proportions are different from what we are used to”. (Photo by Elena Kalis)

Kagome Co's employee Shigenori Suzuki tries to eat a tomato which is fed to him by the newly-developed “Wearable Tomato” device for runners, during its unveiling event ahead of the weekend's Tokyo Marathon in Tokyo February 19, 2015. The eight-kilo (17.6-pound) contraption fits on a runner like a rucksack. It can distribute a total of seven medium-sized tomatoes, one by one, at the click of a button and supplies the runner with much needed nutrients during a long jog or race.
