Odorant shape and vibration likely lead to olfaction satisfaction

21-Sep-2012

A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules.The study, in the journal Physical Chemistry Chemical Physics, demonstrates the feasibility of the theory – ...

Illinois researchers use pyrosequencing to study canine intestinal bacteria

16-Aug-2010

A dog's indiscriminate taste is not always a positive trait. In fact, it often leads to gastrointestinal infections and consequent ailments such as diarrhea and vomiting that come from eating spoiled food. Others develop gastrointestinal diseases such as inflammatory bowel diseases that are not ...
