In Science and elsewhere, claims about using small forces to pull molecules apart seem fabricated High profile journals are retracting papers byChristopher Bielawskis University of Texas, Austin, team amid an investigation into scientific misconduct. The moves followAngewandte Chemiesretraction of a 2012 paper from Bielawskis team in January 2015.A former research group member admitted to falsifying and/or fabricating data affecting this article, theAngewandte Chemienoticestates. Notices of concern regarding papers inScience, Journal of the American Chemical Society (JACS) Journal of MaterialChemistry,Polymer ChemistryandChemical Sciencehave been published in the past few months and now the first retractions of these papers has been coming into effectone paper in Scienceandthree inJACS. While many authors contributed to these papers, just two are common to them all: Bielawski and his former PhD studentKelly Wiggins. Bielawski is now at the Ulsan National Institute of Science and Technology in Korea, a move he tellsChemistry Worldhad been in the works for several years. For all other questions, he said hed been asked to direct enquiries to the University of Texas.Chemistry Worldwas unable to reach Wiggins for comment.

Microbreweries are cranking out special stouts, IPAs, lagers and pilsners. And the flavors and aromas of each of those brews all come down to chemistry. This week, in honor of St. Patrick's Day, Reactions takes on craft beer chemistry.

Do you love quad IPAs with high alcohol content, or pistachio cream ale and stout beer infused with bacon? A new video in the American Chemical Society's "Reactions" series shows how chemistry makes microbrews like these come to life. The clip, released in celebration of St. Patrick's Day, points out that all beers, from the generic cheap swill to the high-end, flavor-infused microbrew, are made the same way. Start by heating a grain in water until enzymes turn the starches into a sugar solution called wort. Then, throw in some hops and yeast, and let it ferment long enough to turn it into alcohol. That's basically all there is to it, though you can dramatically change the way your beer looks and tastes depending on which types of grains and hops you use. And you can even add things like essential oils to give a beer the exact flavor and aroma you're looking for. To learn even more about how chemistry plays a significant role in the brewing process, check out the video at the top of this post. And be sure to grab a bottle of your favorite brew while watching so you really appreciate what went into making … Continue reading →
