Water is the most ubiquitous fluid on Earth, and plays a foundational role in life as we know it. And yet the complexity of this seemingly simple molecule remains a vigorously debated area of scientific research to this day. Writing in the most recent issue of Nature Physics, Professor of Physics Francis Starr provides a commentary on recent research to uncover the mystery of water’s unusual properties.
“We all learn as children that oil and water don’t mix,” Starr writes. ” If there was only one fluid – say just the water – then “unmixing” should not even be a possibility. However, it turns out that evidence suggests that, under unusual supercooled conditions, water can unmix from itself, forming two distinct fluids, both of which are pure water. And it turns out this unusual behavior just might help explain many of water’s other unusual and vital features.”
Nature Physics, part of the prestigious group of Nature journals, is published monthly.
Starr’s research at Wesleyan focuses on computational approaches to understand the emergent complexity of soft and biological matter. His lab has explored DNA modeling and nanotechnology, lipid membrane dynamics, and polymer films and composites. Undergraduates and graduate students work together in the Starr lab, emphasizing connections to experimental results.
