An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: Reyhaneh Farimani, University of Vienna, and her colleagues showed that for the simplest case of connected ring pairs, the type of linkage – chemically bonded vs. mechanically linked – has profound effects on the dynamic properties under continuous shear. In these cases novel rheological patterns emerge. In addition to being recently published in the prestigious journal Physical Review Letters, the study received an "Editors' Suggestion" for its particular novelty.

People with symptoms of insomnia may be likely to increase their drinking over time, according to a study published in Alcohol: Clinical and Experimental Research. In the study of adult drinkers, people who had worse insomnia symptoms at the outset of the study tended to increase the amount they drank and the number of times they binge drank during the subsequent year. The researchers found that, even at subclinical levels, insomnia symptoms were a significant predictor of future drinking in adults, suggesting that insomnia symptoms should be addressed to help reduce the risk of problem drinking.
