New Research Identifies Protein Integral to Sperm Development and Male Fertility

Early in the development of sperm, a strange event happens: the X and Y chromosomes condense into tight packages and are sequestered away from the other 44 human chromosomes. If any part of this process goes awry, the cells cannot mature into sperm. Researchers in the College of Biological Sciences have now identified an important link in this process — a little-known protein called ATF7IP2.

New Findings Shed Light on Pancreatic Cancer Treatment Targets

Pancreatic cancer is the third leading cause of cancer-related deaths in the United States and only 12% of patients survive five years after being diagnosed. Severe pancreatic cancer is associated with metastasis, and it is this spread of secondary tumors that usually causes death, but little is known about the molecular mechanisms that drive metastasis.

Understanding Neutrophil Decision-Making: How Immune Cells Prioritize Competing Signals

Neutrophils, the primary foot soldiers of the immune system, swarm to sites of infection and inflammation by following breadcrumb pathways made up of signaling molecules. But the human body is a complex place, and neutrophils are often simultaneously bombarded with multiple signals, some of which are more important than others. For example, signals of infection or tissue damage require more urgent attention than signals produced by other immune cells.

Chloroplasts Do More Than Photosynthesis; They’re Also a Key Player In Plant Immunity

Scientists have long known that chloroplasts help plants turn the sun’s energy into food, but a new study, led by researchers in the Department of Plant Biology, shows that they’re also essential for plant immunity to viral and bacterial pathogens.

Chloroplasts are generally spherical, but a small percentage of them change their shape and send out tube-like projections called “stromules.” First observed over a century ago, the biological function of stromules has remained enigmatic.

From Tide Pools to Policy: CBS Graduate Student Leads in Environmental Research and DEIJ Advocacy

Elena Suglia, a soon-to-graduate Ph.D. candidate in the Population Biology Graduate Group, has spent her time at Davis tackling the “inextricably intertwined issues” of environmental protection, environmental justice, and equity.

In recognition of her leadership in working at the intersection of science and public policy, Suglia was awarded the 2023 Emerging Public Policy Leadership Award from the American Institute of Biological Sciences.

Dean’s Mentorship Awards Recognize Outstanding Graduate Student Mentors

Mentorship in the life sciences plays a crucial role. One generation helps the next, and together new discoveries are made, techniques are developed and skills are honed, by both mentor and mentee.

The CBS Dean’s Mentorship Awards, which are made possible through donations to the college’s Annual Fund, recognize exceptional graduate students who have mentored undergraduate students in the lab and classroom. This year’s recipients were honored at a college award ceremony on Saturday, June 3.

Creativity and Commitment: Fellows to Present on Efforts to Foster Diversity and Inclusivity

In the College of Biological Sciences, principles of diversity, equity and inclusion are guiding principles. As such, an array of special DEI-related programs led by graduate students, each of whom was awarded a Graduate DEIJ Leader Fellowship for the 2022-23 academic year, will culminate in an open house event highlighting their achievements from 1:00-3:00pm on June 8, in Walker Hall.
