Is there an formula that can measure the 'popularity' of ratings?

Posted: 17 Jul 2021 02:06 PM PDT

For example, 1,000 upvotes and 10 downvotes would be considered much more popular than 5 upvotes and 0 downvotes despite the fact that the first case has more downvotes.

On the other hand, 200 upvotes and 800 downvotes would be considered much less popular than the original 5 upvotes and 0 downvotes despite the fact that the first case has more upvotes.

Is there a methodology that can be used to objectively measure how 'good' certain ratings are?

Does the pancreas produce insulin in anticipation of food?

Posted: 17 Jul 2021 04:27 PM PDT

As a type 1 diabetic I have to administer insulin some time in advance of eating. In the same way that someone salivates when expecting/smelling food, does a normal pancreas release insulin or "get ready" to release it?

Are all retroviruses dangerous and lethal?

Posted: 17 Jul 2021 05:50 PM PDT

I know we have HIV the most notorious and well known of them all but i hear that there is an abundance of retroviruses out there. Are there any ones that are spread through air or droplets?

Do all of them prove to be lethal to their infected hosts?

Are male animals that possess extremely ornate feathers or other decorations compared to the more down to earth and dour females of the species considerably more likely to suffer from predation than females due to their lack of camouflage?

Thinking about an animal as basic as a mallard duck and how the male is considerably more eye catching with its bright green head, white neck ring and contrasting white and dark areas on the rest of the body. In contrast the female has a dull but prudent coloration that lends itself well to blending into reeds and other vegetation.

There's lots of other animals like this, Peafowl males notoriously have to lug around their cumbersome display feathers in addition to the bright coloration for example, while the female Sage-Grouse seem to be able to blend into the prairie much more comfortably than their partners.

Does this have real world repercussions for the survivability for either sex broadly speaking? Because I'd imagine that females have better luck when males almost seem to be advertising their presence to anything with eyes.

Do Wet Bulb conditions (conditions where humans cannot physically cool down) ever occur in the tropics/sub-tropics?

Posted: 16 Jul 2021 01:11 PM PDT

I heard about such a thing happening in Canada of all places, so it got me wondering why I haven't heard about such a thing while struggling through the heat and high humidity down in South Carolina.

For Plants that can be sexed, are only the female plants able to produce fruit?

Posted: 16 Jul 2021 04:37 PM PDT

My wife told me about recent conspiracy theory that landscaping and agriculture businesses basically all male plants so when they pollinate they cannot produce fruit. Do only female plants produce fruit or are they just more productive when making fruit?…
