Tiny microenvironments hold clues to ocean nitrogen cycle

Tiny microenvironments hold clues to ocean nitrogen cycle

April 20, 2018

A new Rochester study shows that nitrogen-feeding organisms exist all over the deep ocean, and not just in large oxygen-depleted “dead zones,” changing the way we think about the delicate nitrogen cycle.

Scientists discover gene controlling genetic recombination rates

Scientists discover gene controlling genetic recombination rates

April 19, 2018

Genetics is a crapshoot, with genes from both parents combining and recombining to produce combinations unique to each offspring. While genetic recombination is vital to natural selection, there is always a risk that “selfish DNA” will enter the mix, causing abnormal crossovers that can manifest as birth defects. Some species have evolved to display far more crossover than others, and scientists in Rochester have discovered a gene in fruit flies that is responsible for the evolution of these recombination rates.

We think we’re the first advanced earthlings—but how do we really know?

April 16, 2018

Imagine if, many millions of years ago, dinosaurs drove cars through cities of mile-high buildings. A preposterous idea, right? In a compelling thought experiment, professor of physics and astronomy Adam Frank and director of the NASA Goddard Institute for Space Studies Gavin Schmidt wonder how we would truly know if there were a past civilization so advanced that it left little or no trace of its impact on the planet.

Schumer announces plan to protect and expand LLE

Schumer announces plan to protect and expand LLE

March 5, 2018

U.S. Senate Minority Leader Charles Schumer announced a three-part plan to protect and expand the University of Rochester’s Laboratory for Laser Energetics (LLE) during his visit to the LLE on Monday, March 5. The Trump Administration’s Fiscal Year 2019 budget, announced last month, proposed significant cuts to the lab and a “three-year ramp-down” in federal support. During his visit, Schumer praised the LLE for creating jobs and advancing scientific research in physics, optics, and photonics. “The Laser Lab is vital not only to Rochester but to the United States and our national security,” Schumer said. “Turning out the lights on the Laser Lab is a horrible idea, and I promise you, it will not happen under my watch.” (University of Rochester photo / J.
