Subjected to high-frequency sound waves, stem cells extracted from fat tissue grow into new bone cells. Audible sound waves are useful too, as this latest innovation from a London-based designer shows: her portable speaker doubles as an air purifier. Internal ventilators along with the music’s waves remove harmful particles from the air and drive them into a special filter...

Tap water can be made lead-free using a simple filter. Now, an Estonian startup has developed a wearable solution for those with allergies triggered by substances in the air. The team’s 300g device is worn around the neck. Mini ventilators on the bottom absorb air, and 99.9% of pet hair, pollen, dust or mould contained within is captured by...

Flexible travel is now possible for people with limited mobility - thanks to a tailored search engine and an app which provides assistance for those changing trains. Now, a woman from London is helping the capital’s underground users select the healthiest route. Even below the surface, the air quality index of 25 particles per cubic metre is exceeded through...

Inventive genius isn’t age-restricted. In recent times, school-age children have developed a lead filter for water taps, while this 23-year-old student created a new smog filter. Air quality is equally important for a 12-year-old English girl whose mother has asthma. She developed a rucksack which filters polluted air, incorporating an air filter and ventilators onto the front of her...

Self-driving electric haulers could soon be hitting railway tracks. Meanwhile, an American startup has developed a system which removes CO2 from the atmosphere during rail traffic. Air flows in through an aperture on top of a container car stationed in between track vehicles. The CO2 is extracted and stored within a chamber, with clean air flowing out through the...

Fresh air, also when cycling, keeps us healthy. Now, an engineering student from India has founded a startup so that his compatriots can benefit too. The 23-year-old has invented a machine which absorbs the harmful elements of smog, such as black carbon, and captures them in a large container. The human-sized devices cost less than a new mobile phone...

Fresh air sharpens our senses. Inside, plants can too. But potted plants can never purify our air completely. Most organisms that cleanse the air of pollutants are found in the roots. That is, in the soil. Which is why a Canadian startup has developed a moving wall providing even more freshness in rooms. Different types of plant are grown...
