Women freeze faster than men.

Your knowledge of that sounds kind of ominous... :o

In Howard's defense, I assumed he means "freeze" in the colloquial sense of "feel uncomfortably cold", not in the physical sense of "change into a solid crystallized state". :p ;)

[ThaHoward]

Technically your cells might crystalize from freezing. For example frost bites. That is frost crystals forming in your tissue and killing it.

And yes, it is the old and usual thing of saying i.e "it's so cold! I'm freezing!" No need to argue on semantics.

An EF5 tornado releases more energy than the bomb which leveled Hiroshima.

It's inaccurate to say that we descend from apes. Because as hominids, we are apes. Planet of the apes isn't science-fiction, it's just reality.

Women freeze faster than men. However men die of freezing before women.

This is correct and the reason behind it is due to men having more testosterone which contributes to muscle growth, and muscles generate heat. To put it very basically, testosterone=muscles, muscles=heat.

(Refrains for going into a whole tangent about science of muscle adaptation :P)

Last year, several articles ran about why offices tend to run colder than really needed, especially these days, and it's because the formula used to calculate the amount of air conditioning (and power) is based on the male body type [more muscle mass, etc.]. Men tend to run hotter than females due to more bulk. At one point, men dominated jobs found in office buildings, now they don't.

Here's a New York Times article about it: Chilly at Work? Office Formula Devised for Men

The math and science wizards will love the formula in the article.

Office Air Conditioning Is Cold for Women; Science Reveals Why

[Nidwin]

At the second 100 Year Starship Symposium, White told Space.com, “We're trying to see if we can generate a very tiny instance of this in a tabletop experiment”, the project is a "humble experiment" but said it represents a promising first step, “The findings I presented today change it from impractical to plausible and worth further investigation.”

So there's a chance that warp tech made a very small step in the right direction.

[XYZ96]

There's a mutation on Chromosome 3 that makes people either partially or fully immune to HIV(-1) infections.
They become immune due to not having a certain protein (CCR5) on the outside of their cells, HIV needs this protein to enter the cells.
Full immunity, caused when you have two mutated genes, is rare, partial immunity, when you only have one mutated gene, (making infection harder and less severe) isn't rare but still uncommon.

After extensive observations, XYZ96 is appereantly a human and not a devil.

Giraffes cannot step down. If they try, they fall forward.

Well in that case I must be a fricking Amazon. LOL! I have always had huge muscles for a female and I am always WAY too hot in even 72F, maybe that's why I am never cold in a -40 winter!

They say average women carry more body fat than men, talking already healthy people here not fat people. So that would provide more insulation against actual freezing.

[ThaHoward]

Men's symptoms are actually stronger. So "manflu" is a thing :P

We need to impart that mutation to people.

Colour doesn't objectively exist outside our visual senses it is wavelengths of light photons hitting three cone cells in our eyes. Our brains have three values to work with and they create what we think of as colour from those.

There's some very interesting research going on about people evolving a 4th color sense. The researchers were having trouble coming up with tests to perform to see if it was even real or not but what was really interesting is that they found that people are taught to perceive color and that the human brain saw more color shades and depths after noticing basic shades are different. In other words, once the brain created another category for a color it then began sorting more colors into it.

The same mutation renders people immune to bubonic plague.

I wasn't saying that was an absolute (all men/all women are this or that) nature and science doesn't work in absolutes, so you, as a female having huge muscles isn't really abnormal and as the saying goes in archeology "God doesn't work with straight lines", to indicate a difference between a man made structure and a natural one, nothing is clean cut or black and white. Also, in reference to body fat percentage, yes, women tend to carry more body fat than men, however the difference in fat and muscle is that muscle produces heat whereas fat merely insulates and the body breaks down fat for various purposes, your fat wouldn't protect you as long as muscle mass would.

Colour doesn't objectively exist outside our visual senses it is wavelengths of light photons hitting three cone cells in our eyes. Our brains have three values to work with and they create what we think of as colour from those.

That's anthropocentric reasoning. Objectively, the photons have different wavelengths, whether we see them or not.

True... but transferring an fluid continuum of a wavelength spectrum into a small number of discrete "colors" is the result of the human observer. Photon wavelengths are obviously part of physical nature, and (most likely) independent of who perceives them or not; the arrangement of these into bands of colors, however, is purely a product of human minds trying to interpret and categorize these wavelengths, while making use of a sensory organ that is anatomically biased in specific ways.

So, sometimes, anthropocentric reasons are the most scientifically sound ones. ;)

Course photons have different wavelengths but colour isn't an intrinsic property of them.

Also look at the visual variance in how different people and cultures perceive colour subjectively.

"Several years ago, researchers showed some of the Himba tribe a circle with 11 green squares and one blue.

The study found they could not pick out which one was different from the others, or took much longer to make sense of it.

However, the same tribe has many different words for green. When they were shown squares with one green a different shade, they could pick it out immediately.

Another study focused on how Russian speakers have separate words for light blue (goluboy) and dark blue (siniy).

MIT recruited 50 people from the Boston area in Massachusetts, half of whom were native Russian speakers.

They found they were 10 per cent faster at distinguishing between light (goluboy) blues and dark (siniy) blues than at discriminating between blues within the same shade category."

Actually I'd take the oppossing view, anthropocentric reasoning would be that the universe is a literal reflection of how the human brain and visual cortex translates different frequencies of light wavelengths into colour.

[fissiparity]

From a conversation I had recently with a long term student of practical and academic anthropology (concerning the objectivity of achromatic colour grey);

"All color is a product of our visual cortex making sense of different wavelengths of reflected light.

Light is that part of the electromagnetic spectrum that falls in what we call the visible light range. Visible light consists of a variety of frequencies that our eyes can perceive.

Our brains translate these frequencies into color.

When visible light strikes or falls upon any object, some portion of it is absorbed, and some portion is reflected. Its that portion thats reflected that we perceive as the objects color.

Objects which absorb most or all of the visible light we see as black. Those which reflect most or allWhite. Grays are produced by a sort of mixture of the two Those of us with some arts training know we can produce grays with opposing colors.This is used in the production of shadow tones.

SoDo gray tones exist outside of human sight? Sure. Many animals have no color perception at allThey see everything in terms of grays Black and white as we say."

The largest dinosaur footprint ever was recently found. Close to 4 ft long.

Human beings don't need to breathe air. Some liquids can provide oxygen just as well as air, and sometimes even do a better job.

In The abyss, the scene of the rat breathing liquid was made without any tricks. The rat was breathing oxygenated perfluorocarbon (I tried to find which molecule exactly but I still don't know for sure which one was used here ; the most commonly used for this are perflubron and perfluorodecalin).

The reason why elephants have stubby toe is, with their weight, longer toes would break when they step on them.

The Berenstein Bears are actually the Berenstain Bears. Nearly everyone remembers it as being the former. This has led to the popular Mandela Effect theory on the internet, while science simply calls it confabulation.
