Researchers are using the power of the sun to upcycle plastic waste.
The recycling rate of commonly used plastics is less than one percent, but that accounts for nearly a third of all the waste, in all the landfills, worldwide. Researchers are looking to harness the power of the sun, in a climate-friendly process, to upcycle plastic waste, in hopes of increasing the ...This is an NSF Multimedia Gallery item.

Researchers are working to improve radiologists ’ interpretation of AI data.
The wide range of applications for artificial intelligence alone are impressive. Researchers used mammograms of breast cancer to compare radiologists and AI assessments, to understand how AI and humans look at the images and find regions of potential concern. They learned, when you pair up human ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

A team of researchers have developed a high-speed, 3D microscope, called MediSCAPE.
When doctors need to remove a sample of body tissue for closer examination, they perform a biopsy, a procedure that can create stress and anxiety in patients. MediSCAPE is a high-speed, 3D microscope that provides real-time, detailed images of live tissue cells that might someday make biopsies ...This is an NSF Multimedia Gallery item.
