Probing Protein Adaptations in Extreme Environments

Extremophiles are organisms that thrive, or at least tolerate, extreme environmental conditions, such as the high temps and pressures found near under-water hydrothermal vents, or the freezing temperatures of permafrost soils. To survive these uncomfortable climates, organisms have had to undergo adaptations, specifically molecular adaptations that change the behavior between their biomacromolecules to reflect the […]

Studying Radical Movements Under Pressure

Radiation is a hazard to all living organisms, damaging cellular systems at the molecular level.  Much of this damage is not due to the direct impact of radiation on cells, but the interaction of radiation with water to produce reactive oxygen species that react with and degrade biomolecules.  Like tiny bombs, these small molecules diffuse through the
