Biology researchers Vera Gorbunova and Andrei Seluanov report that the “jumping genes” in mice become active as the mice age when a multi-function protein stops keeping them in check in order to take on another role. A protein called Sirt6 is needed to keep the jumping genes—technically known as retrotransposons—inactive.
Biologists Vera Gorbunova and Andei Seluanov have discovered one reason for the the increase in DNA damage as we age: the primary repair process begins to fail and is replaced by one that is less accurate.
For the first time, the middle-steps in the process that creates the protein-making machinery of bacterial cells—called the ribosomes—has been isolated. A new study by biologist Gloria Culver suggests that blocking these pathways may help kill off drug-resistant bacteria.
A newly-discovered species of ant supports a controversial theory of species formation. “Most new species come about in geographic isolation,” said Christian Rabeling, assistant professor of biology at the University of Rochester. “We now have evidence that speciation can take place within a single colony.”
The University’s dining services has been ranked 6th on the 2014 list of 75 Best Colleges for Food by the online publication The Daily Meal. In addition to the quality of the food, the rankings were determined by the “food scene of the surrounding area,” as well as nutrition, sustainability, accessibility, events, uniqueness, and “the overall quality of the dining experience.”
Rochester biologist Michael Welte and his team made their discovery while studying the internal mechanisms of the egg cell of the fruit fly, known as Drosophila. What keeps the assembly line functioning—based on the new research—is a protein called Klar.
Findings on the cellular-level regulation of proteins called histones by lipid droplets, or “fat depots,” shines light on chromosome production – and possible manipulation of that process.
When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. A new technique keeps the stem cells in place, resulting in faster and better tissue regeneration.
Daniel Weix, assistant professor of chemistry, has been selected as one of 14 Camille Dreyfus Teacher-Scholars for 2014, an award given to faculty members in the chemical sciences who are within the first five years of their academic careers and who have demonstrated outstanding scholarship and commitment to education.
