Adhesive from trees could make tape more eco-friendly
The stuff that makes your tape sticky comes from fossil fuels. Now scientists have used tree wastes to engineer a “greener” tape adhesive — one kinder to the environment.

Scientists Say: Kelvin
Kelvin is a temperature scale. It’s based around the concept of “absolute zero,” a temperature so cold that molecules stop moving.
