Cornell scientists have developed a novel technique to transform symmetrical semiconductor particles into intricately twisted, spiral structures – or “chiral” materials – producing films with extraordinary light-bending properties.

The discovery, detailed in a paper publishing Jan. 31 in the journal Science, could revolutionize technologies that rely on controlling light polarization, such as displays, sensors and optical communications devices.

Chicken consumption has doubled in the U.S. since 1980, breezing past beef in 2010. But nearly three-quarters of production costs in the industry are bound up in what the birds eat.

Spent grain from the brewing industry offers a huge opportunity for animal agriculture, with about 36.4 million tons produced as waste annually. Brewers’ spent grain (BSG) is frequently upcycled and used as cattle and hog feed, but chickens cannot efficiently digest such fiber-rich ingredients.

Now, in a new paper appearing in the Journal of the American Chemical Society, a team of researchers from Cornell and the University of Wisconsin report new catalysts which exhibit superior ORR activity and robust stability. The team has characterized metal–organic framework-derived nonprecious dual metal single-atom catalysts (SACs), consisting of Co–N₄ and Zn–N₄ local structures.

Summer Engineering Research for Community College Students (SERCCS) selects 2 students from (2-year) community colleges for eight-week internships in accelerator and x-ray sciences research, during which students also
