See-through Zebrafish May Hold Clues to Ovarian Cancer

by Greg Watry

For thousands of years, animals have helped humans advance biomedical research. Early Greeks, such as Aristotle and Galen, studied animals to gain insights into anatomy, physiology and pathology. Today, model organisms, like mice, help researchers understand human diseases, opening the door to potential defenses and new therapies.

Genome Project Aims to Restore Health of Redwood and Giant Sequoia Forests

By Ann Filmer

Some trees are better at surviving drought, fire, pests, and diseases than others. By identifying the genes responsible for these adaptations, scientists can compile a scalable database that will aid resource managers as they plan long-term conservation strategies, particularly as the climate changes.

UC Davis, Johns Hopkins University and Save the Redwoods League are working together to protect this iconic tree.

Professor David Neale, UC Davis Department of Plant Sciences, showed in preliminary research that it is feasible to sequence the redwood, which has a genome 10 times larger than ours. Redwoods are “hexaploid” with  six copies of each chromosome compared to humans’ two copies.
