For Thanksgiving, my little family wants to have a picnic in a pine forest. But which one? Can you recommend a place within 90 minutes of the Twin Cities that has a pine forest where we can lay our blankets on a bed of pine needles? Bonus points for: not crowded, not a 5 mile hike from the car with picnic, and postprandial pretty hiking options.
I found this in a coffee can of seashells in the basement of my new house. It's about three inches long, and an inch and a half wide. It has a somewhat rough texture. The house is in Illinois about 7 miles from the Mississippi. Anyone have any ideas? Photo here

Does anyone have suggestions for early winter birding in Oregon & Northern California? [more inside]
I recently saw an article about burning and then "un-burning" iron powder, allowing the same material to be burned over and over again as part of a renewable energy system. Dang, I have so many questions! [more inside]
I've always been interested in quick mental math/arithmetic. e.g. Sometimes I find myself checking a bill by adding it up the way we were taught in school. I'm sure there are better ways. What are the best books/resources? Looking for math techniques that can be used often, are easy to remember and easy to use!
I'm interested in understanding the historical paradigms of thought around pharmacology and the concept of medicine - not medical practice in general, but specifically ingesting various substances to produce healing. [more inside]

Working with my psychiatrist, I'm continuing a years-long taper off of a psychiatric medication (in IR tablet form) that I have developed an extreme physiological dependence on. Compounding services aren't financially viable for me in the long term, so I am planning on preparing my own solutions of appropriate dosages. Because of the therapeutic dose of this medication, I am going to need to have the ability to accurately measure liquid in very small amounts. Any professional chemists (or the like) have suggestions for me? [more inside]
What are the best science magazines written for the layperson? Ideally, these feature articles that are well-written and high quality. Ideally articles put new ideas/discoveries/findings in appropriate context in the field and discuss the degree of validity / extrapolation appropriate, and are written by science-focused journalists. I'm fine with some sensationalism (to provoke interesting thoughts!), but would like it strongly tempered with appropriate skepticism and adherence (duh) to the scientific method. [more inside]
I'm thinking of giving my character an interest, or maybe even degree, in mycology. I'm working in the life sciences but besides hunting mushrooms in my childhood and seeing a bizzare documentary about slime molds or lichen have no clue about the field. Is there some book/film/documentary where I can pick up something about it? [more inside]
I am writing a demographics paper for a graduate program I'm in, and I am not sure of the best way to graph several different variables. Talk to me like a child. [more inside]
I can't figure out how to google this. I have blue eyes and so do both of my parents. But I'm curious about how having recessive genes from both sides affects gene expression. [more inside]
I'm trying to understand why shopping is often listed as a low risk activity for COVID exposure. If COVID is transmissible by aerosol as the science seems to indicate, shouldn't spending time in an indoor, semi-ventilated space be considered a higher risk? Or is it because of the lower concentration of people and expected spacing and movement (compared to say, sitting in a restaurant)?
I read a study or an article a few months back that described the efficacy of therapy in terms of years progressed. As in, they asked study participants how many years of growth they had experienced while in therapy. And through this they found some sort of expected ratio like "one year of therapy produces the same amount of personal growth as non-therapy (normal) years" Do you know what this study or article is?
When spiders' egg sacs hatch naturally without human interference, do they do so all at once, or one at a time? [more inside]
