I hope everyone had a great weekend. One of my posts got featured on the radar, which was a nice surprise, and I’d like to welcome all my new followers!
1. In response to this and this. You’re right that the margin of error in the dating results don’t detract from the awesome discovery. The margin just means that the we can’t know the exact date the fossil was created, but instead the narrow range that it falls within.
2. Sleep learning has been discredited since we acquired the ability to monitor brain activity in the 1950’s.
3. I do indeed answer (almost) all of the questions I get. To be honest, I don’t have a good answer for you as to why people seem to enjoy their own odors. One thing I do know is that scent is highly related to genetics and the cellular markers that make you specifically you. Therefore, our attraction to our own scents may have something to do with the brain’s recognition of its own cells and byproducts. But that’s just a guess! Thanks for the question.
4. You may have to be more specific about your gripe with antibacterial soap. If you’re against handwashing in general, I’m afraid that the expert advice is against you. There are some concerns about the chemicals found in antibacterial soap, but it’s too early to say anything definitive. A nuanced approach might be to limit using antibacterial soap, but the results of one or two students certainly aren’t enough to justify swearing off soap.
5. I’m not sure exactly what you want to know. I am very skeptical that we will ever establish a permanent colony on the moon. Considering we’re already starting to see a crunch on resources due to overpopulation, I can’t see how flying a civilization’s worth of supplies to the moon could be feasible. My guess would be that, if a base is ever established on the moon, it will be a small research or private one, and it will be a long way in the future.
