Pictured at left is the queen ant of the parasitic species Mycocepurus castrator. This ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.
The University ranks as the number one destination for graduates of the African Leadership Academy (ALA), a selective college preparatory program in South Africa. Last week the University hosted the academy’s 4th annual indaba, meaning “gathering” in Zulu – the largest conference in North America for students who have graduated from ALA.
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.”
“This internship has been the most enriching, most difficult, most thought-provoking, and heartbreaking experience,” said Humma Sheikh ’15, rising senior, a neuroscience major.
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.
Humans have a well-documented tendency to see winning and losing streaks in situations that, in fact, are random. Now in the first study in non-human primates of this systematic error in decision making, researchers find that monkeys also share our unfounded belief in lucky streaks.
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.
