Extracting proteins from pottery: Researchers advance proteomic profiling of ceramic artifacts

By Lisa McDonald / September 28, 2021

There are relatively few examples of successful recovery and identification of archeological protein residues from ceramic artifacts. Researchers led by the University of Catania in Italy looked to advance the application of proteomics to ancient ceramics by investigating prehistoric pottery from the Maltese Bronze/Iron Age site of il-Qlejgħa tal-Baħrija.

Video: An easier way to temper chocolate

By Lisa McDonald / September 8, 2021

Producing chocolate with a shiny, smooth texture and good “snap” requires a complicated heating and cooling process that, on the large scale, is performed using expensive machines. University of Guelph researchers discovered a potentially easier way to achieve the desired texture by modifying the amount of phospholipids in chocolate.
