Part IV. Assembling the details and making the case for a novel paramyxovirus This is the fourth in a five part series on an unexpected discovery of a paramyxovirus in a mosquito. In this part, we take a look at all the evidence we can find and try to figure out how a gene from…

Part I. The back story from the genome record Together, these five posts describe the discovery of a novel paramyxovirus in the Aedes aegyptii genome and a new method for finding interesting anomalies in GenBank. I. The back story from the genome record II. What do the mumps proteins do? And how do we find…

This the third part of case study where we see what happens when high school students clone and sequence genomic plant DNA. In this last part, we use the results from an automated comparison program to determine if the students cloned any genes at all and, if so, which genes were cloned. (You can also…

This the second part of three part case study where we see what happens when high school students clone and sequence genomic plant DNA. In this part, we do a bit of forensics to see how well their sequencing worked and to see if we can anything that could help them improve their results the…

In its simplest sense, we imagine that learning occurs through a series of positive and negative rewards. Some actions lead to pleasure, others to pain, and it seems reasonable to expect that people will repeat the actions with pleasurable results and avoid those that ended in pain. Yet, we all know people who aren’t deterred…

Believe it or not, there is the remote possibility that I may get to have some influence in getting a web application built, that I can use in teaching, that will do something that I want. Unfortunately, I know very little about the relative merits of AJAX/JavaScript vs. Flash vs. a custom C++ plug-in, that…

The University of Virginia does. They survey students every year to find out what they’re up to tech-wise. Apparently 99% of their first year students own computers. And, a large majority of those computers are laptops (3058/3113 or 98%). And, what’s on those laptops? Let’s have a drum roll:

I’ve been writing quite a bit this week about my search for a cross platform spread sheet program that would support pivot tables and make pie graphs correctly. This all started because of a bug that my students encountered in Microsoft Excel, on Windows. I’m not personally motivated to look for something new, since Office…

I think all of us; me, the students the OO advocates, a thoughtful group of commenters, some instructors; I think many of us learned some things that we didn’t anticipate the other day and got some interesting glimpses into the ways that other people view and interact with their computers. Some of the people who…

Okay OpenOffice fans, show me what you can do. Earlier this week, I wrote about my challenges with a bug in Microsoft Excel that only appears on Windows computers. Since I use a Mac, I didn’t know about the bug when I wrote the assignment and I only found out about it after all but…
