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.
Experiments have created the conditions capable of producing a fusion yield that’s five times higher than the current record laser-fusion energy yield. The new work represents an important advance in a long-standing national research initiative to develop fusion as an energy source.
Until now, it was thought the cracks on icy moons such as Pluto’s Charon were the result of processes like plate tectonics. But new computer models suggest that the pull exerted by another object might have been the cause.
Rochester researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve. Their framework helps explain how the rotation of stars, their emission of x-rays, and the intensity of their stellar winds vary with time. According to Eric Blackman, professor of physics and astronomy, the work could also “ultimately help to determine the age of stars more precisely than is currently possible.”
