Q&A: Biologist earns raves for work with yeast

Q&A: Biologist earns raves for work with yeast

March 16, 2016

LISTEN: David Goldfarb, professor of biology, researches yeast as a model organism for understanding the aging process in humans. Why does this essential ingredient in bread and beer make a good research specimen?

‘Selfish’ DNA flouts rules of inheritance

‘Selfish’ DNA flouts rules of inheritance

February 24, 2016

If researchers aren’t careful, they may be hoodwinked into thinking that a selfish gene is one that has some evolutionary advantage, says Daven Presgraves, an evolutionary geneticist at the University of Rochester.

Scientists map genome of common bed bug

February 2, 2016

“There’s an explosion of insect genome sequencing right now,” said Jack Werren, a professor of biology and a member of the research team. “But the bed bug is particularly interesting because it’s a human parasite, a major pest, and has a unique biology.”

So far, researchers have made little progress in solving the mystery or determining how other long-lived species beat cancer. One exception involves naked mole rats.

Do naked mole rats hold the key to defeating cancer? Ugly rodents produce hybrid protein that prevents tumour growth

February 5, 2015

The researchers hope it may now be possible to use this newly discovered protein to develop new treatments that can help stop cancers from spreading or even developing in the first place.

An extra protein gives naked mole rats more power to stop cancer

February 4, 2015

Naked mole rats are small, hairless, subterranean rodents that have never been known to get cancer despite having a 30-year lifespan. A new protein discovered by biologist Vera Gorbunova may help explain why.

Parasitic DNA stops “jumping” when protein takes charge

Parasitic DNA stops “jumping” when protein takes charge

September 23, 2014

Biology researchers Vera Gorbunova and Andrei Seluanov report that the “jumping genes” in mice become active as the mice age when a multi-function protein stops keeping them in check in order to take on another role. A protein called Sirt6 is needed to keep the jumping genes—technically known as retrotransposons—inactive.

Absurd Creature of the Week: The naked mole rat could one day save your life

September 12, 2014

Biologist Vera Gorbunova studies these creatures at the University of Rochester. She says naked mole rat societies, which can reach 300 individuals, are more like dictatorships than monarchies because anyone with the gumption can ascend the throne.

Less effective DNA repair process takes over as mice age, biologists find

Less effective DNA repair process takes over as mice age, biologists find

September 9, 2014

Biologists Vera Gorbunova and Andei Seluanov have discovered one reason for the the increase in DNA damage as we age: the primary repair process begins to fail and is replaced by one that is less accurate.
