Reply to What makes a strong immune system? by hodlboo
I think this is a difficult question to answer. The immune system isn't like a muscle, where it really only does one job. You've eliminated the primary defense from your question (skin, cilia, mucus), but the secondary, innate system and the tertiary, adaptive system, all have a large number of roles.
- Anti- bacteria
- Anti- fungal
- Anti-viral
- Anti- parasitic
- Anti-cancer
Your immune system's ability do deal with any of those things has a lot of variables (nutrition and genetics to some extent). Your innate system will use different cells for each of those pathogens. Your adaptive response will vary to a large degree as well.

Humanized mouse model. They translate pretty well.

I had the opportunity to read some palliative medicine books at one point. Something that was brought up frequently was hoe a sense of helplessness and other negative emotions could heighten the perception of pain. I didn't look at the year of publication, but it didn't seem like a new book. I don't imagine these Cannabis findings are a surprise to anyone in the game of reducing suffering in humans.

I'm crazy for clover. I wish it was used on public grounds more. Thank you for the suggestion, I'm looking forward to falling down that rabbit hole!

Can it be useful with current farming equipment though? I wonder if adaptations can be made to the equipment.

Reply to Eli5 : is the order of the colors in a real rainbow always the same? and why , whichever it is? by Just_a_happy_artist
Violet has the shortest wavelength, so the greatest chance to interact with a more dense medium. This slows it more than blue, which is more than green... you get the idea.
Hitting straight on you wouldn't notice, but at an angle, it causes the light to bend (think of driving a car, then slowing the left wheels more than the right, the car will turn).
Because the Violet portion bends the most, it ends up on one end, and the red (which bends the least) ends up on the other.

Reply to How do they know what the inside of the earth is made of, along with the internal temperatures? by Kozzinator
Waves, when moving from one medium (material type) to another, will bend if they strike at an angle. They will bend one way if moving unto a less dense medium, the other way if entering a more dense medium. Earthquakes generate massive waves in the earth. By measuring how long those waves take to reach different seismographs (tools for measuring Earthquakes), scientists can determine how the wave moved through the earth, and through that path, the density of the materials the waves moved through.
Temperature data is hypothesized based on the material we know the upper mantle to be made of (from lava) and its density and then supported by deep holes we have dug, where thr Temperature increases in a fairly linear manner.

I'm absolutely going to give this problem to my math class after the break!

To add to this, the PNW range is made from subduction of two or more plates. Hawaii exists due to a Hotspot that the oceanic plate is moving over. Imagine a candle over moving paper, the flame burns through occasionally.

Reply to Do forests have natural life cycles, or will they go on indefinitely without interference? by WhereIdIsEgoWillGo
Trees, yes. Forrests, maybe not how you are thinking. Theyare referred to as "stochastic". Trees fall, other species move in for a bit, old tree type returns. Fire wipes out a patch, grasses, followed by bushes reclaim, but the Trees come back. Over a long enough time scale, because of Tectonic motion, the Trees may end up at a latitude they are not well adapted to. The forests that once grew on the land thar is now Antarctica certainly got well and truly screwed.

Reply to comment by HaloGuy381 in A cougar was observed swimming 1.1 km (0.68 miles) to an uninhabited island in Pugent Sound.

In bed with a cougar can be a positive.
