A robot removes algae from ships’ hulls autonomously. Now, a Norwegian startup is using automated technology to combat mildew and fungal mould on grapevines. Here, too, there is no need for chemicals, as the electrically-powered robot doesn’t employ oil or sulphur, but soft UV-C light. The latter specifically breaks up the DNA of pests and viruses while protecting the...

A ring can control light switches and air-conditioning units. Now for people who rely on working dogs comes a British research team’s wireless control for household devices. Born out of the team’s extensive experience of working with charities and dogs, the blue auxiliary device is easy for owners’ canine companions to recognise. They can be trained to switch it...

Rapidly spreading algae makes construction materials more sustainable. High numbers of shore crabs likewise disrupt the maritime ecosystem. Which is why a Danish startup is collecting the invasive beach- and ocean-dwellers using crab baskets or passive fishing nets. Once caught, crab flesh and shell are processed separately into flour and used as animal- or fish-feed supplements. Crab meal powder...

Skin cancer is treatable with soap made from salicylic acid and Vitamin A. Meanwhile in California a research team has discovered Vitamin D’s cancer-fighting potential. Pancreatic tumours are often surrounded by protective connective tissue (or fibroblasts), making it hard for medication to reach cancer cells. However, a particular molecule in the tissue is activated by Vitamin D, which in...

A membrane filters wastewater and runs on its own electricity. Inspiration, perhaps, for a US research team, which has created a solar panel from black metal to make seawater drinkable without pre-treatment. Key here: special surface treatment of the metal. Tiny laser-cut grooves make the metal permeable to water without affecting its ability to absorb sunlight. Through the capillary...

Coffee grounds are a versatile thing: used in everything from sustainable concrete to glasses frames, even offering natural oils for cosmetics. But as a cocoa alternative? It might sound far-fetched, but that’s exactly what a USA-based startup is trying to achieve. The logic is simple enough: from a taste perspective there are similarities between coffee and cocoa. First the...
