Chromatography in Greek means to ‘write with colors.’ It is a versatile separation technique developed in 1903 by Mikhail Tswett, a Russian botanist. He separated colorful plant pigments using a column of calcium carbonate. Ever since its discovery, chromatography has evolved as a powerful tool in the lab for the separation and identification of different compounds in a mixture.

Study provides insight into the structure of prion proteins responsible for diseases

Prion diseases are a group of rapidly progressive, fatal and infectious neurodegenerative disorders affecting both humans and animals: Bovine Spongiform Encephalopathy (BSE) or 'mad cow' disease is one of the most famous since in 1996 scientists found that the agent responsible for the disease in cows, is the same agent responsible for the so-called variant Creutzfeldt-Jakob Disease (vCJD), a disease affecting humans.

Researchers develop a new way to assess bean composition in coffee

People worldwide want their coffee to be both satisfying and reasonably priced. To meet these standards, roasters typically use a blend of two types of beans, arabica and robusta. But, some use more of the cheaper robusta than they acknowledge, as the bean composition is difficult to determine after roasting. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have developed a new way to assess exactly what's in that cup of joe.
