It's difficult to know how motivated a fly is, and how motivated behaviors change with experience. To do this, we've been developing new ways to measure operant learning in flies, as described in our new Open-LA paper below.

Ever wonder how individuals decide what to eat & what to avoid? We used our novel #OperantLearningAssay (Open-LA) to let #Drosophila control their sensory world and study their motivated choices over time. Read my full work with @karlakaun.bsky.social & co-authors at doi.org/10.1242/jeb....

If you are a mentor for Native students, please keep in mind that some students are staying connected with their ways of life. Not all, bc forced assimilation has led to some Natives being removed from land and family, so not every Native needs time like this.

I spent most of 30 years in the Lower '48 earning my degrees and getting training. During grad school I only had the funding and time to return every 3 years, on average. I've only been home in the winter once in the last 20 years, when my aunt died. Subsistence living is year round. I missed a lot.

To all parents of school age kids: University labs train nearly all people going into science in the US, which is about 25% of the US workforce. These budget cuts to the NIH and NSF means your kids won’t be able to get trained to be scientists. This crisis is putting your kids’ future in peril.

Human embryo editing against disease is unsafe and unproven — despite rosy predictions | Nature
Mathematical modelling suggests that it is theoretically possible to reduce risk of common diseases using heritable genome editing. Scientists argue that the technology involves considerable risk and uncertain benefits. Pitfalls of heritable genome editing undermine theoretical benefits.
