As the Associate Librarian for Collection Development at Harvard, Hazen oversees the acquisitions of one of the biggest library systems in the world. On the first floor of Widener, among the hundreds of stacks and hundreds of students on laptops, Hazen writes reports that emphasize a digital future.

...came into plain view when the researchers started experimenting with the rodents' diet. When one group of mice was fed a typical Western diet, high in fat and sugars, they tended to gain weight and grow more Firmicutes gut bacteria and fewer Bacteroidetes. In mice given a low-fat plant-based chow, the distribution of the two groups of bugs flipped and the animals remained lean. It's not clear whether the balance of gut bugs causes weight gain or is a result of it, but the findings suggest that a "gut profile" could potentially serve as a diagnostic tool...
Gordon also found in his mouse populations that changing the animals' diet caused a dramatic and rapid shift in the population of bacteria in their gut. Switching a mouse from low-fat plant chow to a high-fat Western diet resulted in an explosion of Firmicutes in less than...

"The most probable hypothesis is there was some accident that affected one or more points in the transmission system," a statement from Itaipu said. The area suffered unusually fierce storms on Tuesday, which could have played a part...
