A scientific fact/tidbit you recently learned that you thought was interesting

80+% or so have an innie as opposed to an outie, but belly button aficionados have so many shape breakdowns that a pure round concavity occurs less often than you would think.
 
Until recently, I thought it was just some form of perception bias. But when standing around a camp fire, the smoke really does tend to always blow towards you.

I should have been more specific and/or detailed (I was on my tab) and checked auto-correct hadn't buggered things up. Must take more care...

Approximately 10% of humans have outward facing navels.

Yeah, that post was (due to tablet and keyboard, at least that's my excuse) rather buggered up. 10% are 'outie'.
Less AI meetings, more sleep.

Human jaw shrinkage - jaws have been progressively getting smaller and oral cavities lower in volume within the past several thousand years.

Kind of scary thinking of all of the people getting braces and having teeth pulled these days. And sleep apnea?!

Just yesterday I saw an AYFKM* internet ad -- Joe Rogan plugging a system for strengthening your jaw. My impression was that it would lead to all sorts of TMJ problems.

*Are You ******* Kidding Me?

I'm guessing no one's jaw hit the ground when they learn about that.

Tongue exercises can help to reduce snoring.

My wife has been very happy since I took this route.
 
Skipping everything else and answering the OP question...

I just found out that pineapples are bromeliads. They're the only one that fruits, all other bromeliads flower.

A long time ago I learned that the strawberry is a member of the rose family. Only recently, I learned that raspberries and blackberries are also in the same family.

Oh, and also apples, almonds, peaches ......
 
Only sort of a scientific fact, but I just found out why Pringles all have the same shape: they are made from the same kind of powder used to make instant mashed potatoes and molded. For the same reason, they cannot legally be called "chips".

Reminds me of "almost pizza".

At least they don't actually look like potato chips vs having to double check to make sure the ice cream you are picking up actually says ice cream on the label.
 
Astronomers have captured hundreds of mysterious filaments pointing towards the Milky Way’s supermassive black hole. galaxy. The strange horizontal strands are 25,000 light years from Earth, with scientists comparing them to the dots and dashes of Morse code floating through space. They spell out "We apologize for the inconvenience."



I might've made the last bit up.

This one needs some 'splainin'. As the words are used by botanists, all flowers produce fruits and all fruits come from flowers, so every species in existence does both or neither. Could this have meant that pineapple plants are the only bromeliads that produce a fruit we would normally think of as fruit in the culinary sense, and/or that other bromeliads' flowers are more like what we normally think of as flowers in the "getting flowers from the florist" sense?

Plums & cherries & apricots & nectarines are not only members of that family but even members of the same genus as almonds & peaches.
 
Peach makes sense as a stonefruit... did almonds lose their fleshy "shell"? [emoji15]


And what might an almond fruit have tasted like? Half of y'all are trying to imagine that right now. (not a huge almond fan, myself)

The trees still produce that. We just take it off before sending the nuts out to customers because nobody likes it. The same thing is also true for pecans & walnuts.
