Berkeley Lab scientists join an international collaboration to understand how archaea and bacteria work together deep in a cold sulfur spring

In the fall of 2010, Hoi-Ying Holman of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) was approached by an international team researching a mysterious microbial community discovered deep in cold sulfur springs in southern Germany.

“They told me what they were doing and said, ‘We know what you contributed to the oil-spill research,’” recalls Holman, who heads the Chemical Ecology group in Berkeley Lab’s Earth Sciences Division. “They wondered if I could help them determine the biochemistry of their microbe samples.” (more…)

Chromosome Painting: Discovering beauty in DNA

Everyone has a genetic story.

For artist Geraldine Ondrizek, an art professor at Portland’s Reed College, her story begins with the tragic loss of her child to a condition caused by a genetic anomaly. It’s a story that starts with her efforts to piece together her family’s genetic history and that has brought her, in the years since, to a beautiful intersection of science and art that today defines the very essence of her work.

Since 2001, Ondrizek has worked with geneticists and biologists to gather images of human cellular tissue and genetic tests relating to disease, ethnic identity, and the depiction of genetically inherited conditions. (more…)

Images Capture Split Personality of Dense Suspensions

Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals a decidedly non-viscous side. University of Chicago physicists recorded this surprising behavior in laboratory experiments using high-speed photography, which can capture action taking place in one hundred-thousandths of a second or less.

UChicago graduate student Marc Miskin and Heinrich Jaeger, the William J. Friedman and Alicia Townsend Friedman Professor in Physics, expected that the dense suspensions in their experiments would behave strictly like viscous liquids, which tend to flow less freely than non-viscous liquids. Viscosity certainly does matter as the particle-laden liquid begins to exit the nozzle, but not at the moment where the drop’s thinning neck breaks in two. (more…)
