The designer Alicja Biała and the architect Iwo Borkowicz have created an art installation in Poznań, Poland, which visualises data on climate change. Known as "Totemy", this attention-grabbing installation occupies the space underneath the MVRDV Bałtyk tower and consists of six wooden totems in colourful geometric shapes displaying statistics on climate change. They also feature QR codes that can be scanned to find out more about the artwork and data basis, which has a strong reference to Poland and aims to convince climate change sceptics.

The American founder Lindsay McCormick has developed an environmentally-friendly alternative to toothpaste in tubes called "Bite". Made of natural ingredients, this dental hygiene product consists of pills sold in small glass bottles. The "Bites" are placed in the mouth and are then made to foam using a regular, wet toothbrush. Customers can sign up to a four-month subscription in the online store and have the biodegradable refill pouches in the flavours of "fresh mint" and "activated charcoal" conveniently delivered to their homes.

The clothing-retail company H&M supports the start-up the DO School in a program for young people who need help in finding out what they want to do after school or vocational training. The six-month program includes workshops on a range of topics such as personality and soft skills, as well as training for the modern working world. The participants are between the ages of 16 and 22 and also do a 5-week internship in the various departments of an H&M store. This gives the company a highly effective employer branding among this young target group, for whom the program is free of charge.

The confectionery company Cadbury has celebrated "World Chocolate Day" in Melbourne with a campaign that invited residents to make chocolate using a 3D printer. For this purpose, a large 3D printer for milk chocolate was installed in the Myer Chadstone department store, where shoppers could print their own creations and make charms. They also got the chance to personalise the chocolate in different shapes and decorate it with letters, signs and Australian symbols. The charms are therefore not only ideal for immediate consumption, but also make great gifts.

Researchers from Kyushu University have for the first time successfully created a laser diode based on organic semiconductors and thereby opened the path towards new applications in the fields of biosensing, displays, healthcare and optical communications. Previous attempts failed due to the high current required by such devices to achieve the lasing process. The new diode consists of a highly efficient light-emitting material with a relatively low resistance to electricity. A grid-shaped structure made of insulating material around the electrodes achieves the desired optical effects.
