Book recommendations on how the brain impacts the body

I'm interested in learning more about the science of mind-body connections, especially in the mind-impacts-body direction. For example, I'm curious about how mental exertion can lead to physical fatigue, or how an emotion can trigger physical symptoms in the body (such as indigestion from stress). I'm looking for an interesting and accessible book on this topic, if one exists. [more inside]

What's that darn river called?

I read a while ago about a stretch in a particular river that's very dangerous because it's very narrow and looks calm, while in actuality it's extremely fast and deep. People try to cross it, or they get in, and boom. That's it. Does anyone know what I'm talking about? I've utterly failed at googling, and for some reason it's really bothering me. [more inside]

I'm looking for all thing unusual, little known and also ATOMIC

The other day I read this thing about ATOMIC GARDENING And apparently this controlled mutation is the reason we have ruby red grapefruits. So my question is what ELSE is atomic that I didn't know about? Is there anything else using radiation unconventionally or atomic technology in novel places I didn't suspect?

Math / probability question re: HIV

I'm trying to calculate the probability of contracting HIV for the husband of an infected woman. Given a risk of 10-50 conversions per 10,000 exposures. And assuming an average frequency of sexual acts of 2-3 X per week. That's 100-150 sexual acts /year. That should give about a 10%-15% yearly risk of contracting HIV, right?

How far do I need to be from a highway/parkway to no longer hear it?

How far do I need to be from a highway/parkway to no longer hear it? I hope to use this information to look at a map and find the nearest place that will be quiet in the middle of the night, to record sound. Local road noise or the occasional passing car is not a concern, just highways and parkways that will be busy all night.

UK fungus ID groups/materials?

I'm looking for a UK-oriented fungus identification online group or guide or website or book or Android app. Recommendations based on personal experience are most welcome. Poking around online has led me to a few places, like Mycokey, but either the varieties aren't listed or I'm just rubbish at describing what I've found. [more inside]

Anna's hummingbirds vs bees on Salvia leucantha (Mexican sage)?

There are a lot of Anna's hummingbirds and a lot of bees here. They both like a big Mexican sage. Yesterday I saw several hummingbirds in series dive down near the sage then pull up sharply with a sudden 'tweet' noise like a short blast on a whistle. Why are the birds doing that? [more inside]

Is there a service that will tell me if it's going to be a nice sunset?

Or failing a service, is there a way to tell, ahead of time, whether or not a given sunset will likely be a colourful one? I have the perfect spot already, about 650' about sea level, and all of the camera equipment I'm going to get. What I need to know is what to look for in the weather conditions that will make a difference. Which type of clouds will be the most fortuitous, are there particular weather patterns that will help, etc?
