An international team of astronomers – including 17 Cornellians – report they have found the first faint, low-frequency whispers that may be gravitational waves from gigantic, colliding black holes in distant galaxies. The findings were obtained from more than 12.5 years of data collected from the national radio telescopes at Green Bank, West Virginia, and the recently collapsed dish at the Arecibo Observatory, in Arecibo, Puerto Rico./news/astronomers-find-possible-hints-low-frequency-gravitational-waves
How do perceptions of luck shape views about inequality and redistribution? Could interventions nudge hiring managers to evaluate job candidates blindly, and thus more objectively? Has remote instruction during the pandemic improved student interactions and equity in science labs?
From a mountain high in Chile’s Atacama Desert, astronomers with the National Science Foundation’s Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in the universe. Their new observations plus a bit of cosmic geometry suggest that the universe is 13.77 billion years old, give or take 40 million years./news/new-view-natures-oldest-light-adds-twist-debate-over-universes-age
Chaos and uncertainty are hallmarks of armed conflict. But new research that ties together multiple aspects of political violence reveals universal dynamics in how conflicts emerge and expand. The work provides a statistical framework that could one day help anticipate deadly violence./news/data-armed-conflict-reveals-patterns-violent-chaos
The first mention of the word “coronavirus” in a Cornell Chronicle story in 2020 came on Jan. 29, when the university designated mainland China as an elevated-risk destination, and imposed travel restrictions on students, faculty and staff./news/2020-review-covid-19-was-story

Craig Wiggers grew up in Alabama. During his 25-year career in the U.S. Marines he served in Iraq and Afghanistan. So when he moved to Ithaca as a Cornell ROTC instructor in 2012, he wasn’t quite sure what to do with snow.
“At first my wife and I spent our winters staring at the walls and waiting for spring,” said Wiggers, now director of administration at the Department of Physics in the College of Arts and Sciences (A&S)./news/biathlon-e-book-aims-insight
Even though a crystal of electrons was first predicted in 1934, a method for achieving it had remained elusive./news/researchers-trap-electrons-create-elusive-crystal
