How can we describe a population expanding into a new environment, like an invasive species spreading into virgin territory, or a disease infiltrating a community of susceptible hosts? Would the speed at which the population’s front advances be constant, like a car driving along a highway, so that if it travels 60 miles in one … Continue reading Muskrats, Arts and Crafts
(A follow-up to my election day post.) Tuesday’s surprising presidential election has been on everyone’s mind for the past week, and has stirred up lots of emotion. I thought it worth acknowledging this event at the start of class on Thursday. My aims were that this would be very brief, that I wouldn’t expresses displeasure … Continue reading Post-election-day biophysics
(A short election day post!) I always start off my “biophysics for non-science majors” class with an interesting picture. Today, since it’s election day, I tried to think of something that links politics and science and came up with these photos that I took at the Library of Congress this past summer, where there’s a … Continue reading Election day biophysics

[Update: Note Eric Johnson’s comment on the sunshades! Update: Lara Nesselroad, below, notes that there is an informational placard next to the artwork!] The Science Library here … Continue reading Science Sketches and Café Cartoons
[Edit, Sept. 25, 2016: In retrospect, this is a confusing post. The overall point is fine, but my contrived illustration is not a good one.] At an otherwise excellent talk some time ago, the speaker put up a graph like this (look below — not the cheetah)… …and said that the two sets of data points, … Continue reading You may not be interested in noise, but noise is interested in you
An extremely long post, mainly written to have something to point people to as a commentary on some recent work. A new paper from my lab came out recently in PLOS Biology, on watching and learning about the competition between gut microbes. I like the paper a lot, and, with one possible exception, it took more hard labor … Continue reading How are your intestines like a tide pool?
A few evenings ago I gave a “science pub” talk — part of a long-running series of public presentations that the Oregon Museum of Science and Industry runs at several sites in the state. (This was at a local pizza place, so thankfully I could just bike to it.) I called the talk “Glimpses of … Continue reading Science Pub 2016
