Understanding the Mechanisms of Embryonic Cell Behavior

During embryonic development, thousands of cells divide and move as one. Understanding the mechanisms that coordinate this collective behavior remains a significant challenge in biology and the physics of living systems. Researchers from UC San Diego have discovered that avian embryos control their

A Better Understanding of How Gene Editing Tools Work

Patients are being healed with a personalized treatment that repairs the patient’s specific genetic mutation. The treatment was created using a form of gene editing called base editing —a method created by UC San Diego’s Alexis Komor. Her latest research outlines the way certain DNA repair proteins

Pollution From the Tijuana River Affects Air Quality in San Diego

A new study from UC San Diego examines how pollutants from the Tijuana River travel and are transmitted in the atmosphere through coastal aerosols. The study found a mixture of drugs and chemicals from tires and beauty products aerosolize from wastewater and are detectable in both air and water.

The Long Pathway to Cell Organization and Growth

Sterols are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic pathways. Researchers from UC San Diego have used a novel approach to show how they interact with other lipids that help cells self-organize.
