Cosmic radiation from supernova altered virus evolution in Africa, study proposes

A new study led by recent undergraduate student Caitlyn Nojiri and co-authored by astronomy and astrophysics professor Enrico Ramirez-Ruiz and postdoctoral fellow Noémie Globus examined iron isotopes to identify a 2.5 million-year-old supernova. The researchers connected this stellar explosion to a surge of radiation that pummeled Earth around the same time, and they assert that the blast was powerful enough to break the DNA of living creatures.

UC Santa Cruz will lead development of next-generation telescope alignment system

The National Science Foundation recently awarded $3.9 million to researchers at the University of California, Santa Cruz as the lead institution for the development of a next-gen telescope alignment system. The researchers will work with an international team to build and test systems in Santa Cruz and eventually install the final designs in seven telescopes at three ground-based observatory sites around the world.
