A new study from the University of Illinois reports long-lasting cognitive impairments in mice when they are administered a chemotherapy regimen used to treat breast cancer in humans.Life SciencesEngineeringPhysical SciencesGenome-editing proteins ride a DNA zip lineAug 15, 2016 1:30 pm886 views For gene-editing proteins to be useful in clinical applications, they need to be able to find the specific site they’re supposed to edit among billions of DNA sequences. Using advanced imaging techniques, University of Illinois researchers have found that one class of genome-editing proteins rapidly travels along a strand of DNA like a rider on a zip line – a unique behavior among documented DNA-binding proteins.HealthLife SciencesReport: People buy most of their junk food at the supermarketAug 9, 2016 9:15 am1028 views An analysis of a nationally representative sample of U.S. adults reveals that access to healthy foods in a supermarket does not hinder Americans’ consumption of empty calories. In fact, the study found, U.S. adults buy the bulk of their sugar-sweetened beverages and nutrient-poor discretionary foods at supermarkets and grocery stores. The findings challenge the "food desert" hypothesis.Life SciencesAncient bones, teeth, tell story of strife at CahokiaAug 4, 2016 10:45 am1595 views Dozens of people buried in mass graves in an ancient mound in Cahokia, a pre-Columbian city in Illinois near present-day St. Louis, likely lived in or near Cahokia most of their lives, researchers report in the American Journal of Physical Anthropology.
