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 third professorship that has been endowed in the Fine family name, this is one of 83 new endowed professorships that have been created during The Meliora Challenge.
Cardiologist Arthur J. Moss will lead a five-year analysis of the genetic condition called Long QT Syndrome, type 3. The research focuses on identifying the basic cellular mechanisms involved in the disorder and any overlap with common heart rhythm disorders.
In a nationwide student, School of Medicine and Dentistry researchers found that a majority of middle-aged men and women eligible to take aspirin to prevent heart attack and stroke do not recall their doctors ever telling them to do so.
Complication rates can vary as much as five-fold among hospitals, prompting researchers to call for the development of a national quality reporting system to improve maternal outcomes.
As a quantum state collapses, it will follow a path known as a quantum trajectory. In a new paper featured this week on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a theory, recently developed by University of Rochester physicists, for predicting the most likely path a system will take.
Chair of Pediatrics Nina Schor followed a hunch about a brain receptor — a hunch that may give researchers a new avenue for testing drugs for autism. “Science doesn’t always travel in a straight line,” Schor said. “Sometimes the importance of a scientific study in one field is what it unexpectedly tells us about another field.”
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.
