Males and females are made different through a diverse assortment of molecular mechanisms--from the XY chromosomal system of mammals to temperature-dependent systems in certain reptiles. In most species, some mixture of hormones, sex-specific transcription factors, and gene regulation carry out the initial instructions of the sex-determining triggers, but the outlines of these pathways have only recently begun to emerge in studies of various creatures.

Gloria Culver has been appointed dean of the School of Arts & Sciences, effective immediately. Peter Lennie, the Robert L. and Mary L. Sproull Dean of the Faculty of Arts, Sciences & Engineering, made the announcement following a yearlong national search. Culver has been serving as interim dean since July 1, 2014.

Kathy Giardina’s position requires her to manage complex budgetary matters within the department—including 30 research grants, faculty start-up accounts, capital equipment accounts, as well as departmental operating and teaching budgets.

We humans tend to assume we rule the Earth. With our advanced tool making, language, problem solving and social skills, and our top predator status, we like to think of ourselves as the dominant life form on the planet.

A protein newly found in the naked mole rat may help explain its unique ability to ward off cancer.
The protein is associated with a cluster of genes (called a locus) that is also found in humans and mice. It’s the job of that locus to encode—or carry the genetic instructions for synthesizing —several cancer-fighting proteins. As Professor of Biology Vera Gorbunova explains, the locus found in naked mole rats encodes a total of four cancer-fighting proteins, while the human and mouse version encodes only three proteins.
The findings by Seuanov and Gorbunova research team have been published in the Proceedings of the National Academy of Sciences.

Choosing between two good things can be tough. When animals must decide between feeding and mating, it can get even trickier. In a discovery that might ring true even for some humans, researchers have shown that male brains – at least in nematodes – will suppress the ability to locate food in order to instead focus on finding a mate.

As we and other vertebrates age, our DNA accumulates mutations and becomes rearranged, which may result in a variety of age-related illnesses, including cancers. Biologists Vera Gorbunova and Andrei Seluanov have now discovered one reason for the increasing DNA damage: the primary repair process begins to fail with increasing age and is replaced by one that is less accurate.

One challenge in killing off harmful bacteria is that many of them develop a resistance to antibiotics. Researchers at the University of Rochester are targeting the formation of the protein-making machinery in those cells as a possible alternate way to stop the bacteria. And Professor of Biology Gloria Culver has, for the first time, isolated the middle-steps in the process that creates that machinery—called the ribosomes.

Christian Rabeling and his team discovered the parasitic Mycocepurus castrator, an example of a still-controversial theory known as sympatric speciation.

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.

Research from Rochester biologists shows that different types of histone proteins need to exist in specific proportions in order not to damage a fruit fly's DNA—and that any over-produced histones are kept in cellular storage facilities until they are needed.
