Y chromosomes are sex chromosomes in males that are transmitted from father to son; they can be important for male fertility and sex determination in many species. Even though fruit fly and mammalian Y chromosomes have different evolutionary origins, they have parallel genome structures, says Larracuente, who co-authored the paper with her PhD student Ching-Ho Chang. “Drosophila melanogaster is a premier model organism for genetics and genomics, and has perhaps the best genome assembly of any animal. Despite these resources, we know very little about the organization of the Drosophila Y chromosome because most of it is missing from the genome assembly.”

Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won’t or can’t mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.

Bacteria cause many serious illnesses, from food poisoning to pneumonia. The challenge for scientists is that disease-causing bacteria are extraordinarily resilient. For example, when bacteria like Escherichia coli (E. coli) undergo starvation, they massively reorganize their bacterial DNA, allowing them to survive stressful conditions.

Throughout his years, Ward developed the large collection that made the University of Rochester and Ward himself famous. Following his death, Ward’s collection bounced around many buildings at the University of Rochester, and the specimens were dispersed. Some specimens ended up in storage in Hutchison Hall, where they lay untouched until about five years ago. Since then, Senior Lecturer of Biology Robert Minckley has been researching the documents and specimens with the help of Melissa Mead (the John M. and Barbara Keil University Archivist and Rochester Collections Librarian) and others. This project is known as the Ward Project, a collaboration supported by the Departments of Biology and Earth and Environmental Studies and the River Campus Libraries (RCL) that aims to capture Ward’s enduring legacy and impact.

Around the world, there’s a higher proportion of specialist bees in arid environments than in humid ones. But scientists don’t know why. “One interpretation is that to survive in really hot, unpredictable parts of the desert you need to be able to be synchronized with that plant very well,” says Bob Minckley, a professor of biology.

Genetics is a crapshoot. During sexual reproduction, genes from both the mother and the father mix and mingle to produce a genetic combination unique to each offspring. In most cases, the chromosomes line up properly and crossover. In some unlucky cases, however, “selfish DNA” enters the mix, causing abnormal crossovers with deletions or insertions in chromosomes, which can manifest as birth defects.

Zhao, Gorbunova, and Seluanov find another piece to the puzzle in naked mole rats’ long, cancer-free life
February 7, 2018
With their large buck teeth and wrinkled, hairless bodies, naked mole rats won’t be winning any awards for cutest rodent. But their long life span—they can live up to 30 years, the longest of any rodent—and remarkable resistance to age-related diseases, offer scientists key clues to the mysteries of aging and cancer.

“Fruit flies can reveal a lot about genetics, disease progression, addiction, crop parasites, you name it,” says John Jaenike, a professor of biology at the University of Rochester. Jaenike, along with Thomas Werner, an assistant professor of biological sciences at Michigan Technological University, recently coauthored an open-access field guide, Drosophilids of the Midwest and Northeast. The book documents the physical and behavioral characteristics of fruit fly species in the titular regions and is the first comprehensive guide to fruit flies published in nearly a century.

Because anticancer drugs are designed to kill growing cells, they also affect normal, fast-growing cells—blood cells forming in the bone marrow, for example, and digestive, reproductive, and hair follicle cells. Chemotherapy may also affect cells in vital organs, such as the heart, kidney, bladder, lungs, and nervous system.

At the height of his career, only a half dozen other researchers in North America shared William Muchmore’s interest in pseudoscorpions – small arachnids with pear-shaped bodies and pincers similar to scorpions, but without the tails. After all, they were not known to have any economic or medical importance. They were also small and “tedious to study,” said the former University of Rochester biology professor, who died in May at the age of 96.

On a clear, cool day in mid-September back in 2012, John Jaenike and Thomas Werner maneuvered their way through the forested Tech Trails in Houghton, Michigan, to the mushroom and tomato fruit fly traps Werner had planted a few days prior. Jaenike, an evolutionary ecologist from the University of Rochester, poised his net over a trap that had enticed several Drosophila specimens—each no more than two to four millimeters long. He bent down to begin collecting. “Oh, cool, Drosophila neotestacea!” Werner recalls Jaenike exclaiming as he spotted the very species he planned to discuss during his seminar at Michigan Tech the next day.

The common fruit fly is widely used in laboratory experiments because it can provide insights into the biological processes of other, more complex organisms, including humans. However, what is seen in fruit flies in the lab may bear little resemblance to what is seen in fruit flies in the wild—especially when it comes to the bacteria found in their intestinal tracts, University researchers find.

In a recent study, Rochester scientists made two important contributions to DNA damage research. First, though scientists could previously point to an association between DNA damage and aging, the Rochester group has demonstrated a causal relationship between reduced DNA damage and extended lifespan. Second, the researchers have identified a cellular factor—an enzyme called topoisomerase 2, or Top2, implicated in DNA damage—that can be targeted to reduce that damage. The findings are published in the journal Aging.
