Research scientists urge universities to improve undergraduate science teaching

In the Jan. 14 issue of Science, Washington University in St. Louis biologist Sarah C.R. Elgin, PhD, and 12 other biomedical research scientists recommend seven steps that universities can take to support the teacher-scientist, ranging in difficulty from educating faculty about research on learning or creating teaching discussion groups to creating (monetary) awards and named professorships for outstanding teachers and requiring excellence in teaching for promotion.

Deep genomics: Scientists probe the epigenome

A Washington University in St. Louis team is participating in the modENCODE project, a massive ongoing effort to map all the elements in model organisms that affect whether genes are silenced or expressed. The work supports the more complex ENCODE project, which is tasked to map the same elements in the human genome. While the genome is the same in every cell, each cell type expresses a different set of genes. In people, moreover, roughly 95 percent of the genome is silenced. Together the projects will “put flesh on the bones” of the Human Genome Project, says team leader Sarah C.R. Elgin.

New method takes snapshots of proteins as they fold

Using a sophisticated version of the stroboscopic photography a pioneering photographer used in 1877 to prove that a horse takes all four hooves off the ground when it gallops, Michael L. Gross, PhD, professor of chemistry in Arts & Sciences and of medicine and immunology in the School of Medicine, catches proteins in the act of folding.

BattleBots Battle Royale

Mechanical engineering students maneuver BattleBots during a Battle Royale held Tuesday, Dec. 14. The battle was the final assignment in a freshman mechanical engineering class taught by Pat Harkins, a technical lab technician in the School of Engineering & Applied Science.

Cornstarch might have ended the Gulf spill agony sooner

Last year’s attempt to kill the Macondo well in the Gulf of Mexico by pouring heavy mud down the well bore may have been defeated by an instability that led to turbulent mixing of the oil and the mud. Jonathan Katz, PhD, professor of physics at Washington University in St. Louis, had suggested a simple solution to the problem: cornstarch. Experiments described in an article published recently in Physical Review Letters suggest his solution might have worked.

Champion hydrogen-producing microbe

The cyanobacteria are famous for releasing the oxygen that made the Earth a hospitable planet, but some strains also have a hidden talent for producing hydrogen gas, a potential biofuel. With the help of a few metabolic tricks, a lab at Washington University has coaxed one such strain to produce champion levels of the gas.
