If not, what are the differences?

What is the oldest medicinal technique that is still effective today?

Posted: 27 Sep 2020 10:23 AM PDT

This is a spontaneous question that popped into my mind, and would be interesting to know in the same way it is interesting to know the Romans created so great a many things that we still use today.

How does the immune system differentiate from gut bacteria and other bacteria?

Posted: 28 Sep 2020 01:18 AM PDT

Also, if the gut bacteria were to cause an overgrowth in regions where it's not supposed to, would the immune system act then? Or is the bloodstream completed sealed off from the gut? I am sorry if it sounds stupid, the closest I could find anything similar is a hypothetical Leaky Gut Syndrome

How likely is it to be tested positive a short period of time after exposing to COVID?

Posted: 28 Sep 2020 01:49 AM PDT

For example, after getting the virus in airport or on the plane, is it likely to be test positive at the destination airport?

I am not medical student but I am trying to write a crawler to gather statistic of origins of imported cases in different countries, so I want to know whether exposure during travel has a major impact on the number.

What makes hydraulic brake hoses flexible but non-expandable?

Posted: 28 Sep 2020 01:46 AM PDT

When transferring pressure from the brake lever to the caliper, a brake hose must keep its volume as stable as possible, to avoid any loss of brake pressure from the expanding of the hose.. right?

How does it manage to keep its diameter and volume rock-solid stable and still be able to flex in all directions?

Another way to ask this would be: how does a brake hose manage to be rigid radially and flexible longitudinally? Am I asking this right?

Has the Equable Climate problem been solved?

Posted: 28 Sep 2020 06:52 AM PDT

Hey guys, I was reading about paleoclimates and paleoecology and came across the term "Equable Climate problem". From what I understand it basically is the fact that during the Eocene the world's climate was almost uniformly warm. I looked more into this and found some theories about it describing Hadley cells expanding, cyclones, large lakes, and even orbital anomalies as theories for this problem; however, papers and posts explaining/discussing these theories all appear rather old (most of them are around 10-ish years old).

My question is if there has been any advancements on theories explaining it, have some theories been disproven? (I haven't seen much development on the theory of Hadley cells expanding and the disappearance of polar cells, so maybe that theory has been disproven?), and if there hasn't been any developments on this problem I would also want to know what are your explanations for the Equable Climate problem (out of curiosity).

Thank you all in advance

Did locusts exist in hordes before agriculture?

Posted: 27 Sep 2020 03:17 PM PDT

It seems like it would make sense that they evolved hordes after available food became concentrated (ie farms).

What is stopping the earth's crust from getting as hot as the mantle?

Posted: 27 Sep 2020 09:03 AM PDT

The temperature at the core mantle boundary is 7230F / 4000C, and the temperature of the inner core is 9806F / 5430C, whereas the temperature at the mantle crust boundary is 392F / 200C. Given the extreme pressure, and the fact that the core is constantly radiating its heat up through the earth's layers, what is stopping the crust from heating up?

Ignoring eclipses, do tidally locked bodies like the Earth and Moon have the same length of a day as each other?
