Understanding how bacteria detoxify and eat antibiotics might help us develop ways to address antibiotic contamination in the environment.
Michael Worful

Ten years ago, Gautam Dantas stumbled across a strange phenomenon in the lab: bacteria that were able to feed on antibiotics.

“The story really starts very serendipitously,” said Dantas, who is now a professor of pathology and immunology at Washington University. “Like whoa, there are bugs in the soil that are munching on antibiotics.”

Native St. Louisan Jonathan Losos is a Harvard University biology professor and director of Losos Laboratory at the university. He recently wrote the book “Improbable Destinies: Fate, Chance and the Future of Evolution.

The book follows researchers across the world who are using experimental evolutionary science to learn more about our role in the natural world.

State and local-level school officials would be required to develop guidelines for teaching evolution under legislation making its way through the Missouri House.

If passed, school districts would have to, “encourage students to explore scientific questions” regarding the “strengths and weaknesses” of both biological and chemical evolution.  The sponsor, State Representative Andrew Koenig (R, Winchester), says House Bill 179 stresses academic freedom.

“It does not mandate curriculum to the teacher," Koenig said.  "It’s really up to the school district, and if evolution is gonna be taught, it just allows them to teach the scientific strengths and weaknesses.”

Darwin vs. design

Jan 19, 2012

This article first appeared in the St. Louis Beacon, Jan. 19, 2012 - If a science course taught in any public classroom in Missouri, from grade school through college, includes a lesson on evolution, should it also have to give equal time to intelligent design?

Mammalian Mash-up: Platypus genome shows three animals in one

May 12, 2008

This article first appeared in the St. Louis Beacon: An international team of scientists has sequenced the genome of a duck-billed platypus. Part bird, part reptile and part mammal, the platypus genome sheds light on the evolution of mammals, including humans, and on the genetics of disease. Led by Richard K. Wilson, director of the Genome Sequencing Center at Washington University School of Medicine, the scientific team found that this mammal's DNA is as unusual as its duck-bill.

This article first appeared in the St. Louis Beacon: The Missouri House Education Committee is considering this session an outrageous bill that attacks Missouri education while claiming to improve it. Submitted by Republican Rep. Wayne Cooper of Camdenton as the "Missouri Science Education Act," HB 2554 purports to improve science teaching in Missouri by helping students develop critical thinking skills. Teachers would have to clearly identify what is "verified empirical data" and distinguish it from what is "theory, hypothesis, conjecture, speculation" and the like.
