Tire

A new study shows that lettuce readily takes up particles produced from rubber car tires as they roll along our roadways. The research is part of a growing body of evidence that materials we use everyday are flowing back into our food supply.

A new study has shone a light on the impacts on the aquatic environment of tire wear particles, which the authors say can have detrimental effects on marine species, including growth abnormalities and death.

Armed with a special nanogenerator and a toy Jeep, researchers have demonstrated that the energy wastage caused by friction as car tires roll across the road can be captured and turned into electricity. It's a development that could bring about better fuel efficiency in cars of the future.
