Your clothes can have an afterlife: Strategies for greater reuse and recycling of textiles

Only about 15% of used clothes and other textiles in the United States get reused or recycled. The other 85% head straight to the landfill or incinerator. This wastes scarce resources, contributes to climate change and pollutes ...

Unexpected light behavior may be harnessed to improve optical communications and sensors

Shine a flashlight into a murky pond water and the beam won't penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam, which loses a fixed percentage of energy per unit distance traveled. ...

Study shows everyday plastic products release trillions of microscopic particles into water

Plastics surround us, whether it's the grocery bags we use at the supermarket or household items such as shampoo and detergent bottles. Plastics don't exist only as large objects, but also as microscopic particles that are ...
