Language of chemistry is unveiled by molecular make-up

Posted: Published on August 8th, 2014

DO YOU speak chemistry? Analysing molecular structures as if they were sentences has revealed hidden "words" that are key to their make-up. The approach suggests that algorithms like the ones Google uses in search engines might reveal ways to mix up molecules or invent drugs. Linguists can analyse text by ranking words according to how often they appear. This "bag-of-words" approach can help to distinguish different kinds of texts. For example, the word rankings for spam emails are different to those of genuine messages, which helps algorithms filter out spam. Bartosz Grzybowski of Northwestern University in Evanston, Illinois, and his colleagues wondered if a similar approach could find the most important parts of a molecule. "Chemistry is about recognising certain patterns of atoms," he says. "In linguistics we also recognise patterns: those are words." The team took thousands of molecules, each representing a sentence, and applied a bag-of-words algorithm. By comparing pairs of molecules, they noted arrangements of atoms that appear in both, like a ring of carbons or a particular group that connects to oxygen and hydrogen, and ranked the frequency of these common fragments. The researchers had expected the "words" to correspond to functional groups clusters of atoms … Continue reading

Katherine Heigl Explains Why She Really Quit Greys Anatomy

Posted: Published on August 8th, 2014

Katherine Heigl said recently she quit Greys Anatomy after determining that juggling her work schedule with being a new mom to daughter Nahleigh whom she adopted in 2009 was too much and something had to go. I would come home angry and frustrated that Id missed everything with my kid that day, said the 35-year-old actress in the September issue of Good Housekeeping. I didnt get to wake her up from her nap, or do bath time or bedtime. Id have to sneak into her room and kiss her when she was sleeping, hoping not to wake her up. It was something that weighed heavily on the mind of the Greys Anatomy star. I felt like my priorities were messed up, she said. I was putting so much time and energy into just my work, but I was raised [to believe] that family comes first. Naleigh, now five, was adopted from South Korea, mirroring what Heigls own parents did in adopting her big sister, Meg. My family had its own unique look, she said. And I wanted the one I began with my husband to have the same look, in a way. Two years ago, Heigl and her husband, singer … Continue reading
