Research in David Lab:

In the lab, I utilize techniques in molecular and structural biology, protein biochemistry and enzymology. These skills were cultivated and applied in the process of solving the first full-length structure of an important human base excision repair glycosylase, MUTYH. This work has enabled us to characterize many functional features of the enzyme but has raised additional questions pertaining to the coordination of a zinc ion which is missing from the structure. My current work involves characterizing the structural motif that binds zinc, as well as characterizing naturally occurring cancer variants surrounding this motif. Our structure of MUTYH has also informed a second project, involving the potential discovery of a small molecule inhibitor that binds to a C-terminal substrate recognition motif, thereby diminishing enzymatic activity.

  • Down goes antimatter! Gravity's effect on matter's elusive twin is revealed September 27, 2023
    For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.
  • Decreasing biodiversity may promote spread of viruses September 27, 2023
    How are environmental changes, loss of biodiversity, and the spread of pathogens connected? The answer is a puzzle. Researchers have now described one piece of that puzzle, showing that the destruction of tropical rainforests harms the diversity of mosquito species. At the same time, more resilient species of mosquitoes become more prevalent -- which also […]
  • Study sheds new light on strange lava worlds September 27, 2023
    In a new study, scientists have shown that sweeping molten oceans have a large influence on the observed properties of hot rocky Super-Earths, such as their size and evolutionary path.
  • New insights into the atmosphere and star of an exoplanet September 25, 2023
    A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system's star and its planetary features.
  • Did life exist on Mars? Other planets? With AI's help, we may know soon September 25, 2023
    Scientists have discovered a simple and reliable test for signs of past or present life on other planets -- 'the holy grail of astrobiology.' Researchers report that, with 90% accuracy, their artificial intelligence-based method distinguished modern and ancient biological samples from those of abiotic origin.
