Scientists uncover new way viruses fight back against bacteria
  1. Life Sciences

Using AI to scrutinize, validate theories on animal evolution

By harnessing the power of machine learning, researchers have constructed a framework for analyzing what factors most significantly contribute to a species’ genetic diversity. The study, recently published in the journal Molecular Phylogenetics and Evolution, suggests that the genetic variation of two species, the Brazilian sibilator frog and the granular toad, both amphibians native to […]

Advancements in genomic research reveal alternative transcription initiation sites in thousands of soybean genes

Rosalind Franklin, James Watson and Francis Crick discovered the structure of DNA — that molecular blueprint for life — over 70 years ago. Today, scientists are still uncovering new ways to read it. In 2010, Jianxin Ma, a professor of agronomy, and his collaborators built the first reference genome for soybeans on the widely studied […]

Securin regulates the spatiotemporal dynamics of separase

Separase regulates multiple aspects of the metaphase-to-anaphase transition. Separase cleaves cohesin to allow chromosome segregation and localizes to vesicles to promote exocytosis. The anaphase-promoting complex/cyclosome (APC/C) activates separase by ubiquitinating its inhibitory chaperone, securin, triggering its degradation. How this pathway controls the exocytic function of separase is unknown. During meiosis I, securin is degraded over […]

What Role Can Climate Change Play in the Courtroom? – State of the Planet

Columbia’s Sabin Center for Climate Change Law focuses on four program areas: cross-cutting issues and initiatives, energy law, environmental and land use law, and international and foreign law. As the number of legal efforts involving each of these categories continues to grow, the center has positioned itself as a resource hub for tracking and analyzing […]
