Research finds that chromosomal inversions – which occur when a chunk of chromosome containing tens to thousands of genes breaks off, flips and reattaches – help certain species maintain genetic differences adapted to various regions.
Milkweed has found a new strategy in its epic evolutionary battle with monarch butterflies: structurally upgrading its toxins to outmaneuver monarchs' resistance.
A proof of principle study in mice, six years in the making, shows how targeting a natural checkpoint in meiosis, the process by which sex cells reproduce, safely stopped sperm production.
A new study reveals for the first time the metabolic changes that allow bacteria to survive high doses of penicillin, a classic β-lactam antibiotic. The study also uncovered a weakness in how the bacteria survive, which may help scientists find better ways to fight antibiotic tolerance in the future.
Cornell's Integrated Pest Management program is now in its fourth decade, growing from an effort to reduce pesticide use in agriculture into a statewide model for science-based, economically beneficial pest control to protect crops, public health and the environment.
Susan Henry, former dean of the College of Agriculture and Life Sciences and a molecular geneticist whose breakthroughs in understanding cell metabolism contributed to advances in human pharmaceuticals, died March 7 at age 79.
Researchers at Cornell's Weill Institute for Cell and Molecular Biology have uncovered new evidence that two major types of gene-controlling DNA sequences, promoters and enhancers, operate with a shared logic and often perform the same jobs.
Cornell researchers have uncovered a built-in molecular “gate” that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate blood pressure, brain signaling, and immune defenses. But when levels go unchecked, it can damage cells and disrupt normal signaling.
