Brett Smith for redOrbit.com - Your Universe Online The days of using ball-and-stick models or dusty chalkboard equations have long been over for chemists. Instead, many scientists use complex computer models powered by state-of-the-art processors to work out today’s chemical equations. In recognition of these high-tech models, the 2013 Nobel Prize in Chemistry was awarded to three researchers behind the creation of these complex computer simulations: Martin Karplus of Harvard and the...

U.S.-led researchers say they have created a new model of catalyst design that challenges current ideas about how catalysts function. The study also suggests a method for designing new catalysts. "Catalysts are molecules that speed up chemical reactions without participating in them," the researchers said, noting thousands of industrial and biological processes rely on catalysts. In the human body, enzymes catalyze nearly every reaction. "The Holy Grail of enzyme catalysis and the...
