However, while electric charges exist, magnetic charges have never been observed in nature.

WAIT... what?

https://en.wikipedia.org/wiki/Lodestone

Yes, "Magnetic Fields" certainly do exist in nature, and they are routinely created by the flow of electricity through a wire. 

But, think of this as "Magnetic Charges" versus "Magnetic Fields."

In electricity and magnetism, "Charges" and "Fields" are related phenomena. But, they are also different phenomena.
 

What in the fuck are you babbling about? Yes, a magnetic charge and a magnetic field are different, but you can't have a magnetic field without a magnetic charge, so you're still just amazingly wrong. Have you taken physics or chemistry?

For what it’s worth, I've taken seven (7) quarterly semesters of university level physics, four (4) of them with labs. (That includes one (1) semester, my fourth (4th), entirely dedicated to electricity and magnetism.)

And, I've taken three (3) quarterly semesters of university level chemistry, worth 4.5 credits per semester, all of them with labs worth an additional .5 credits per semester.

Following is a link to the list of SI Electromagnetism Units.

https://en.wikipedia.org/wiki/SI_electromagnetism_units

Let me know if you find a unit for “Magnetic Charge” on that list.

Hint: There’s a reason why you won’t find a unit for “Magnetic Charge” there, or anywhere else.

It occurs to me that your introduction of the “magnetic charge” is much too profound a revelation to be left to linger in the fetid darkness that is this forum. I believe you owe it to the scientific community to bring your revelation to their attention. After all, Gauss missed it when he formulated Gauss’s law for magnetism. Maxwell missed it when he put his four (4) equations of classical electromagnetism together. And, even Einstein missed it while studying Maxwell’s equations to formulate his theory of special relativity.

In fact, your introduction of the “magnetic charge” is so profound, I recommend you skip publishing on arXiv.org and send your manuscript directly to Nature. (Here’s the link to their FOR AUTHORS page: http://www.nature.com/nature/authors/index.html)

Now, it typically takes Nature a couple to a few months to get around to publishing a newly submitted manuscript, so you’re probably not going to make the short list for the Nobel Prize in Physics for 2017. But, on the bright side, those dark energy and dark matter guys aren’t likely to get anywhere soon. So, you’ll be a shoo-in for 2018. And, you probably won’t even have to share the prize money with anyone! After all, they gave a Nobel to Millikan for just measuring elementary “electrical charge,” and he didn’t even theorize or discover “electrical charge.”

Now, the bad news: under normal circumstances, the scientific community would further honor you, immortalize you in fact, by naming the unit of “magnetic charge” the Nigel. Unfortunately, the letter N is already being used to denote the SI unit of force, the Newton. And, the letter m is already being used to denote the SI unit of length, the meter. But, the letter U isn’t currently being used for anything, so I suggest that you could request the unit of “magnetic charge” to be denoted as the “Unicorn.” (Years ago I saw what was advertised to be a unicorn at the circus. But, to be honest, I think it was just a goat with something that kind of looked like a horn glued to its head.) Anyway, my thinking is that since “magnetic charge” is every bit as rare as unicorns, the name is appropriate.

You’re welcome.   

So you're shifting your argument away from "magnetic charge" and specifying that no magnetic monopoles have been found in nature? Well that's true. Have you ever considered being precise in your use of language?

“New evidence that all stars are born in pairs”

As per the article:

‘Astronomers have even searched for a companion to our sun, a star dubbed Nemesis because it was supposed to have kicked an asteroid into Earth’s orbit that collided with our planet and exterminated the dinosaurs. It has never been found.

The new assertion is based on a radio survey of a giant molecular cloud filled with recently formed stars in the constellation Perseus, and a mathematical model that can explain the Perseus observations only if all sunlike stars are born with a companion.

“We are saying, yes, there probably was a Nemesis, a long time ago,” said co-author Steven Stahler, a UC Berkeley research astronomer.

“We ran a series of statistical models to see if we could account for the relative populations of young single stars and binaries of all separations in the Perseus molecular cloud, and the only model that could reproduce the data was one in which all stars form initially as wide binaries. These systems then either shrink or break apart within a million years.”’

Here’s the link to the article: http://news.berkeley.edu/2017/06/13/new-evidence-that-all-stars-are-born-in-pairs/

And, for hardcore astronomy students, here’s the link to the original arXiv.org paper: https://arxiv.org/abs/1705.00049

So monkey brains (and, by extension, very probably /our own/) literally encode faces in the same exact way that a Bethesda RPG encodes faces. That is astounding and hilarious.

Interim results from a FDA-approved clinical trial testing the generic vaccine bacillus Calmette-Guérin (BCG) to reverse advanced type 1 diabetes are being presented at the 75th Scientific Sessions of the American Diabetes Association. The data demonstrate a potential new mechanism by which the BCG vaccine may restore the proper immune response to the insulin-secreting islet cells of the pancreas. Presented by Denise Faustman, MD, PhD, director of the Massachusetts General Hospital Immunobiology Laboratory and principal investigator of the trial, the findings suggest that BCG may induce a permanent increase in expression of genes that restore the beneficial regulatory T cells (Tregs) that prevent the immune system from attacking the body's own tissue. The results are being presented on Saturday, June 10.

Consumer attitudes are being put to the test at Adelaide Central Market with an offering of roasted crickets and ants, mealworm cookies and cricket energy bars.

"We want to further investigate consumers' attitudes towards edible insects, evaluate taste preferences and consumers' willingness to buy such products," says Postdoctoral Fellow Dr Anna Crump, who's working on the project with project leader Associate Professor Kerry Wilkinson and other researchers from the School of Agriculture, Food and Wine and the School of Humanities at the University of Adelaide.

"We will also be asking consumers questions relating to food neophobia -- reluctance to eat novel or new foods. We'll be interested to see if a consumer's ethnicity influences their acceptance of edible insects."

In a preliminary online survey of 820 Australian consumers, the researchers found that 20% had tried edible insects. Of those surveyed, 46% said they would be willing to try a cookie made from insect flour.

"In the earlier survey, consumers said they were most likely to try flavored or roasted insects and least likely to want to try cockroaches or spiders," Dr Crump says.

"In this taste test, we've chosen products that consumers are most likely to react positively towards -- apologies to anyone keen to try a cockroach or spider. The samples we'll be offering consumers provide a good spread of the available insect products in Australia's marketplace, some of which may be more acceptable than others."

Dr Crump says the research will help guide the development of an edible insect industry.

I would think that it is a possibility, but that particular scenario isn’t mentioned in the arXiv.org paper.

As I understand it, the authors believe that the stars in the particular cluster they studied either circle in closer together and remain binary systems, or they separate entirely.

Barring another big mass passing by, I am unsure how they would separate.
