What we’re reading: The vital importance of mosquitoes’ gut microbes, an app for classroom genetics, and how to fish for p-values without really trying

Functional assays showed that axenic larvae of each species failed to develop beyond the first instar. Experiments with Ae. aegypti indi- cated several members of the microbial community and Escherichia coli successfully colonized axenic larvae and rescued development.

The app provides demonstrations of Mendelian inheritance and population genetics, it assists with calculations common in genetics classes associated with these principles (e.g., recombination fraction), and it generates unique practice problems with which students can practice or professors can design assessments.

In the news

“It seems that negative events are necessary and we use them to avoid making the same mistakes again. It doesn’t need to be dramatic, it can be something as apparently positive as constructively worded critical feedback.”

“Wade wants us to cut up human diversity into five races not because that’s what the statistical analyses show, but because thinking about it as a gradient is hard.”

“Our key point here is that it is possible to have multiple potential comparisons, in the sense of a data analysis whose details are highly contingent on data, without the researcher performing any conscious procedure of fishing or examining multiple p-values.”
