Unraveling the origin story of beer yeast

Unraveling the origin story of beer yeast

April 5, 2019

Saccharomyces cerevisiae, or brewer’s yeast, has been used to make beer for thousands of years. To reconstruct the history of modern ale strains, Rochester biologist Justin Fay and his colleagues sequenced the genome of modern brewer’s yeast.

‘Selfish’ genetics amplify inflammation, age-related diseases

‘Selfish’ genetics amplify inflammation, age-related diseases

March 14, 2019

Research from Rochester biologists shows that a class of genomic parasites may cause more harm than previously thought, triggering inflammation that causes age-related diseases.

Male Y chromosomes not ‘genetic wastelands’

Male Y chromosomes not ‘genetic wastelands’

February 6, 2019

The Y chromosome is one piece of the genetic puzzle that is notoriously difficult to sequence. Rochester biologists are finding new insights into the processes that shape the Y chromosome.

What makes a species different?

What makes a species different?

January 2, 2019

New Rochester research points to the presence of “selfish genes,” whose flow among species may dictate whether two species converge or diverge.

Scientists discover gene controlling genetic recombination rates

Scientists discover gene controlling genetic recombination rates

April 19, 2018

Some species have evolved to display far more genetic crossover than others, and scientists in Rochester have discovered a gene in fruit flies that is responsible for the evolution of these recombination rates.

Field guide to fruit flies documents these surprisingly close human relatives

Field guide to fruit flies documents these surprisingly close human relatives

October 4, 2017

The common fruit fly is often deemed an annoying household pest. But these tiny insects are a boon to researchers. Rochester biologist John Jaenike has co-authored the first comprehensive guide to fruit flies published in nearly a century.

Firefly researchers mapping ‘world’s second-most interesting genome’

Firefly researchers mapping ‘world’s second-most interesting genome’

September 19, 2017

“Fireflies only tend to be out during the summer months in Rochester,” says assistant professor of biology Amanda Larracuente. “The end of summer is when we’re frantic about getting all our work done.” Her team is now the first to successfully sequence the firefly genome.

Wasp venom holds clues on how genes get new jobs

Wasp venom holds clues on how genes get new jobs

June 22, 2017

University researchers studying the venom of parasitic wasps believe a relatively understudied mechanism for creating new gene functions may be widespread in other species as well.

Scientists find new gene tool for predicting course of prostate cancer

Scientists find new gene tool for predicting course of prostate cancer

December 20, 2016

Researchers at the University’s Wilmot Cancer Institute and Roswell Park in Buffalo have discovered a possible new tool for predicting whether prostate cancer will reoccur following surgery based on the expression patterns of four genes.

Protein found that initiates DNA repair

Protein found that initiates DNA repair

September 8, 2016

Researchers who specialize in the study of aging have identified a protein that may serve as a first responder, activating a “longevity gene” known as sirtuin 6 and setting in motion a cascade of molecular first responders to repair damaged DNA.
