Giraffe, Gemsbok Genome Assemblies Add to Map of Life

August 12, 2019
The genomes of wild animals can help us understand how they have adapted to unique situations, give insight into their evolution and help in efforts to protect or restore endangered species. Two examples are recently published chromosome-scale genome assemblies for the Masai giraffe and the gemsbok.

Dark Centers of Chromosomes Reveal Ancient DNA

June 18, 2019
Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have changed during human evolution.

Different Strokes for Different Fly Folks: Study Links Reproductive Evolution of Hawaiian Flies to Environment

June 12, 2019
In a new study, UC Davis postdoctoral researcher Didem Sarikaya and her colleagues analyzed egg-laying strategies of 65 different Hawaiian Drosophila species and found that egg-laying capacities diverged in response to their unique environments, which directly affected the number of cells involved in each species’ ovarian development.

Tech-Based Naturalists: Inspiring Citizen Science with the City Nature Challenge

April 15, 2019
Designed with data collection in mind, iNaturalist acts like a pocket repository for all things wildlife and will be used during the upcoming City Nature Challenge, an event held from April 26 to April 29 that encourages people to explore and record the natural world around them, from the city streets to the riparian woodlands.

Discovering Curiosity: Uncovering the Hidden World of Plants with Jennifer Gremer

February 27, 2019
Assistant Professor Jennifer Gremer showed an interest in plant life at an early age, but her path to scientific research wasn’t straightforward. She dabbled in many fields related to plant sciences, from working as an interpretive ranger in Yosemite National Park to performing botanical surveys for the Greater Yellowstone Ecosystem.
