Today I learned about Arthur C. Clarke's The Nine Billion Names of God.

Today I learned about the French Pompeii. According to CNN: The site was apparently covered in ash after a great fire destroyed the town.

Today I learned about Morgan's Wonderland. It's a $32 million San Antonio, TX, theme and water park for special needs children inspired by Morgan and built by her father.

Today I learned that fetal gene expression in the spinal cord, rather than a functional motor cortex, may be the genesis of whether we are right or left-handed. I emphasized may because this study is base on a limited sampling ("five human fetuses).

Today I learned how caffeine keeps us awake. Caffeine is an adenosine antagonist, which is one of the substances produced by the brain's metabolic processes that induce drowsiness. Caffeine works by blocking adenosine receptors, which can cause the emergence of new receptors inducing higher caffeine consumption to block the effects of adenosine. Also, today I learned that an analysis of meta-data shows that human sperm count has been declining since 1973. It's down 59% and is showing no signs of stopping. For some reason, I don't think that decline will have that much of an affect on our population.

Today I learned about the Hyrax. Although you can't tell from the picture, this rodent-like creature is actually more closely related to elephants!

Indeed, the SciShow Psych's host for the link above cautioned that small similarities and shared interests rather than overwhelming genetic similarities could be a fact and referenced limited recent studies (2013 and 2014) suggesting as much.

Today I learned why we are attracted to people who look like us. It seems the attraction could be genetically based because people who share similar genetic traits tend to have more stabile relationships.

Ha!

If not in violation of our administrator's note, many thanks for your insight.

You're quite right; however, the video's host afterwards correctly describes hydrogen peroxides chemical composition. Also, the host does indeed reference more recent clinical findings by the German Cancer Research Center in 2014 on the nature of H2O2 in the body rather than rely on 30 year old references or those supported by a 2003 reference as in the Wikipedia reference you've provided. Although he did not cite a reference, the host does say (4 min. 20 sec. in) that topical hydrogen peroxide has been implicated in "several fatal and near fatal incidents." I'll see if I can find a reference for those incidents.

Today I learned why hydrogen peroxided should not be used to clean wounds. Its interaction with catalase at the wound site causes oxidation that can slow the healing process by damaging cell and entering the bloodstream.

Yes, I think it's all in the tradition of humans training animals for jobs we can't or won't do ourselves. For example, there was a breed of dog, now extinct, that humans bred and trained to operate a hearth rotisserie attached to a treadmill. The breed was treated most inhumanely which, if I recall correctly, may have led to the emergence of the very first animal rights group. Also, today I learned why we have earwax and why its removal, when necessary, should be performed properly.

Today I learned how the CIA tried to train cats to be spies. It was a hilariously absurd idea.

Today I learned why transplanted organs are rejected by a host's immune system. The rejection occurs on a molecular level of protein inactions between the SIRP-a of the transplanted organ and CD47 of the host's immune system.

Chelsea's article regards attitudes of an earlier era, which is supported by the various quotes from the published articles and statements she researched. If you have not fully read the entire article, why should anyone here consider your opinion of Ms. Summers article valid? Given your apparent mindset and disinterest in the details on the subject, why would you even bother to comment?

The linked article in my OP was based on this article by journalist Chelsea Summers. Her article explored and detailed the historical and political implications of pockets and its distinction among the sexes. Chelsea wrote: Chelsea also cited this quote, among others, as a continuing example of the sexist attitude regarding pockets during an earlier era: This article provides a more in-depth discussion of the political role of pockets in women's fashion. I'm male as well, but "evil male pig" are your words not mine.

Let me guess, you're a male and didn't read the article right? I found the article illuminating and its sources credible though you, perhaps, did not.

Today I learned the insidious reason why, historically, women's clothing were without pockets. It seems having no pockets were another way men of an earlier era sought to control women. Later, the fashion industry saw pocketless women's clothing as way to increase sales of handbags and purses.

Today I learned that the oldest stone tools ever found were those found in West Turkana, Kenya. The set of sharpened stones discovered at Lake Turkana date from 3.3 million years ago and predate Oldowan tools by 700,000 years. An amazing discovery of tool making that predates the emergence of modern humans by over 3 million years.

Today I learned that having a photographic memory is a myth; however, eidetic memory is real and common to children not adults. Also, today I learned about an extraordinary letter from Jordan Anderson, a freed slave, to his former master when said master asked Mr. Anderson to return as a paid worker. What a well done response it was.

Cold Mountain, by Charles Frazier. A thoroughly engrossing tail set during American's Civil War era about a man's varied, rich, and harrowing journey home from war to the woman he left behind and the travails she endured. One negative, the frequent use of a derogatory term pertaining to people of color during that era. The story's panoramic descriptions and vivid tail of survivals in the old south rings true to my memories of a harsh but simpler time in my youth.

The linked article described procedures in England but did not mention any other country. Whether eggs are refrigerated in other European countries appears to remain an open question.

Today I learned why Americans refrigerate eggs and Europeans don't. To combat salmonella, American egg producers wash their eggs in a solution that removes a protective "cuticle" coating. The loss of that coating renders those eggs vulnerable to additional contaminants that refrigeration prevents. Europeans prefer to vaccinate their chickens against salmonella rather than remove their eggs protective coating; therefore, refrigeration isn't required.

Please, post links to your sources for those of us who have further interest. Thanks.
