Sustainable 'plastics' are on the horizon

A new Tel Aviv University study describes a process to make bioplastic polymers that don't require land or fresh water—resources that are scarce in much of the world. The polymer is derived from microorganisms that feed ...

The path to reducing plastic pollution

Shuddering and unable to breathe, he vomited up five plastic bags. The small pilot whale, found in a Thai canal this past June, is another symptom of a crisis in the world's oceans. Plastic waste, mostly broken down into ...

Mexican scientists design a new system to control the mistletoe

Mistletoe comprises a group of plants unable to take water and nutrients from the soil, so they have to absorb other plants for survival. These parasitic plants easily reproduce, and in some cases, even kill their hosts. ...

Researchers develop new way to manufacture nanofibers

Researchers at the University of Georgia have developed an inexpensive way to manufacture extraordinarily thin polymer strings commonly known as nanofibers. These polymers can be made from natural materials like proteins ...

Microencapsulation produces uniform drug release vehicle

Consistently uniform, easily manufactured microcapsules containing a brain cancer drug may simplify treatment and provide more tightly controlled therapy, according to Penn State researchers.
