Bacterial Vaginosis and the Secrets of the Vagina's Microbiome - The Atlantic

This is a really long article about a not so pleasant subject, but I did like the title on the website:  "The Superhero in the Vagina", as it lets me make a joke about how it sounds like a rejected Marvel movie title.

Anyhow, the matter of the complicated bacterial balance in the average vagina is kind of interesting.   I wonder whether this is covered in teenage health and sex ed in schools these days?  Sounds like it should...

Fooling your animal

BBC - Earth - How a dog's mind can easily be controlled

It's all about the placebo effect in animals, which seems to be a real thing, even if this article is mainly about the difficulty in studying it.  

Political persuasions of US academia

From a Nature News article about scientists who support Trump (how on Earth did they manage to track down that handful of people?), there's a graphic showing how the political leanings of academics breaks down:

I guess most of this is pretty much what I would have guessed, except I would not have been surprised if engineers had a greater number of conservatives, and I don't really know why mathematicians lean more heavily conservative, too.  (Also, astronomers don't do conservative politics, for some reason.)

Yet more MOND

Hey, I see that my favourite physicist blogger Sabine H has a post up about the new paper which I've been posting about - the one that seems to support the unpopular MOND theory for gravity.

Now, Sabine can be hard to follow when she gets into details, but if you read the post (and the lengthy comments, which get into a bit of an almost philosophical argy bargy about when you give up on a science theory), you get an idea as to why MOND is viewed suspiciously by many. 

Interesting.

Planning for lunar living

An Astronaut Gardener On The Moon - Summits Of Sunlight And Vast Lunar Caves In Low Gravity

Yay - someone who thinks, like me, that it's more sensible to be planning on lunar colonies being the first off Earth permanent colonies for humans, rather than distant, extremely hard to get to, Mars.

This long, long post talks about many aspects of living on the moon.  I haven't read it all yet, but I'll get back to it.

One thing to be curious about - the long term health effects of lunar (or Martian) low gravity.   How can that ever be guessed at until you get people living there for a year or more.  Even more curious - would babies gestated there end up taller, weaker, or what?  I would guess that one of the first things to do on a lunar base would be to raise generations of mice or rats there, and see what happens.   (I also remember some telemovie from - I think - the 1990's that had a mining outpost on the Moon, and the pregnant mother getting spun gently in a centrifuge to provide some artificial gravity to her fetus.  I think she was then heading off to Earth to give birth?  I don't remember much about it - I didn't watch the whole movie.)

Update:  I know that studies have been done with rats raised in centrifuges to simulate a high gravity life, but short of having a centrifuge running permanently on the ISS, the equivalent studies of them raised in low gravity are hard to envisage...

American election comments

*  Donald Trump and his "rigged election" rhetoric is clearly dangerous in a country full of armed-to-the-hilt, conspiracy minded nutters who are encouraged to believe (and easily convinced) that Clinton is a dangerous criminal who wants to take their guns from them.   The mildly worded counterclaims by Republicans (such as Pence) don't seem to be anywhere near enough of a rebuke, and if Trump keeps this up, he really deserves calling out and complete repudiation from the highest levels.  It's much more serious, in its way, than the groping allegations.  (And none of this "he doesn't mean voter fraud - he means the way the media is against him" excuse making I've heard from some of his supporters.)

* There is so little appreciation of the matter of government security classification of communications in the general public that is it easy for them to think that Clinton's classified emails that ended up on her private server were really important stuff.  This is distorting the public perception of her "wrongdoing", and Trump and Republicans are taking full advantage of that.  But even the liberal media is not really helping to clarify public understanding.  This article from back in July sets out this basic point:

An important thing to understand is that the determination of what information is classified is subjective. This means reasonable people can disagree about the relative sensitivity of particular information.

Before coming to academia, I worked for many years as an analyst at both the State Department and the Department of Defense. I held a top secret clearance and worked on issues related to weapons of mass destruction and their proliferation. Debates and arguments about whether certain information should be classified were frequent. More often than not the debates centered on why something was classified in the first place. This is why determining whether Secretary Clinton was careless is not a cut and dried issue.

Well, it's fair to say she was careless - but the consequences of the carelessness are something that is not at all clear, and it is quite possibly very inconsequential from a national security point of view.   

Some pretty incredible work here

Mouse eggs made from skin cells in a dish : Nature News & Comment

Some very science-fictiony stuff here that, I guess, really could make sex redundant for reproduction.  Still need a womb for growing a baby though - I don't think any science is being done on replacing women entirely.  As far as I know... 

Surely you wouldn't, Malcolm

It's reported in The Australian today:

Malcolm Turnbull is being pressured to relax the nation’s gun laws to secure two key industrial reforms in an escalating round of Senate horsetrading, amid a political firestorm over the government’s bid to curb union power.

The government’s workplace agenda is hanging in the balance as Liberal Democratic Party senator David Leyonhjelm demands an expansion of shotgun imports to win his vote for laws to crack down on illegal union tactics across the construction industry.

Malcolm would absolutely kill his moderate credentials with voters if gave in to this from Leyonhjelm.  Surely he wouldn't do it?

Speaking of Leyonhjelm:  I have the distinct impression that he's in a bit of a funk since not only the election, but before it.  Since Helen Dale resigned, actually.  He did only barely get returned due to the double dissolution;  Pauline Hanson and her group of numbskulls has kept his numbskull off the media radar to a large extent since the election; he copped it for speaking ill of a journalist on the very day she died; and now his best mate in the Senate (the very uninspiring Bob Day - surely one of the dullest politicians to be in the Senate for many a year) is quitting.   Leyonhjelm just looks very glum anytime I see him now.  Retire, David; it'll do you good...

What blatant dishonesty

Matt Drudge may have lost his grip on reality - The Washington Post

Problem is, I reckon half of Drudge's readership would not go near the Washington Post for news, and will genuinely go on believing Drudge's dishonesty and propaganda.  

Why hunt bears?

Pedals the bear endeared himself to humans by walking like one. Did hunters kill him? - The Washington Post: The week of agitation over what happened to Pedals coincided with New Jersey’s first bow hunt for black bears in more than 40 years, the Asbury Park Press said. This year, the state’s black bear-hunting season spanned Oct. 10 to 15 for those using bows or muzzleloaders, and will open again from Dec. 5 to 10 for those using firearms. Hunters killed 432 bears in New Jersey last week, according to AP.

Gee. I'm very surprised there is a black bear hunting season at all.   Are they marauding around people to such an extent they need to be culled?   And why pander to the bow hunting fraternity at all?   Surely it makes for a more difficult and painful death if they have to be killed at all.

Kind of glad I don't live in the US...

Update:  I see from this anti-bear hunt Facebook site that many blame Chris Christie for the expanded hunt.   He's not a popular man, and as a sell out to Trump, he deserves it...

Ignoring MOND?

[1609.06642] MOND impact on and of the recently updated mass-discrepancy-acceleration relation

A couple of weeks back, I linked to a report of a new study of galaxy rotation which seemed to be pretty important for what it meant for dark matter.

The link above is to a paper by Mordehai Milgrom, who first proposed MOND, complaining that the paper gave way too little attention to the fact that MOND theories of gravity had predicted this, and it's effectively a strong experimental endorsement of MOND.

It does seem that MOND has a bit of a PR problem in astrophysics.  I see from the Wikipedia article on it at the last link that one of its criticisms is that, at a galactic cluster scale, you still need dark matter to make sense of their movement.  As it says, this makes the theory "less elegant"; on the other hand, it apparently means you can use much less dark matter if you use MOND, which one would think is consistent with the problems of even identifying dark matter. 

Yes, my hunch remains that MOND and Milgrom are unjustly ignored.

I sense a potential for misuse of this study...

Study finds link between marriage attitudes and risky sexual behaviors: This is the first study to investigate links between marriage attitudes and sexual behavior across racial and ethnic minority groups as well as the role skin tone plays in shaping marriage attitudes...

Researchers found that positive attitudes toward marriage had a significant dampening effect on risky behaviors for lighter-skinned African Americans and Asians compared with their
darker skin counterparts, who had more negative attitudes toward marriage. The findings suggest that skin tone plays a role in views toward relationships and marriage, thus impacting decisions about sexual behavior for some people.

I am not at all sure what to make of that!

Excuse me while I talk to monty

Your guest post at Catallaxy has the advantage of not being insane, unlike most of the blog, but I have the following criticisms:

*  did you really have to throw in the "cultural allusion"?:  it reminds me too much of the grand - and nutty - Right wing faux historical prisms that nearly everyone at that blog thinks everything has to be viewed through.  In a way, it reads too much like the grandiose crap that Mk50 used to go on about.  (And, incidentally, he seems to be on some calming medication, or something, now, since he returned under a new identity.  [And why did he bother doing that, when everyone knows who it is?]  He's no longer getting positively excited by the prospect of an American Right wing armed revolution, like he used to.)

* takes too many words to make a point that many - even on the Democrat side - have already made.

* candy was right - the reference to Trump's supporters formerly being the type who would have a country club membership is a tad improbable.  Update:   here's Nate Silver yesterday:

Based on recent polls, I’d estimate that about 35 percent of Trump’s current voters are white men without a college degree, by far Trump’s best demographic group.

  Was this demographic ever into country club membership, monty?

* it's one thing to have sympathy to the economic plight of the low educated under globalisation - and to talk of them having a logical reason for dissatisfaction - but in doing so it risks encouraging them to believe the situation is more catastrophic than it really is, exactly as Trump has been doing.   It also underplays the poisonous anti-evidence based nonsense that the entire leadership of the American Right has participated in for more than a decade as priming Trumpkins to believe any nonsense at all, including that sprouted by their orange buffoon.

I can see how it's not a winning strategy to win hearts and minds to tell people that they are being idiots - yet this is what at least the leadership of the Right needs to be told.   I fear that expressing too much sympathy towards the Trump base makes that job harder to do, and I think that your post reads too much in that direction.

PS:  please pass on the threadsters at Catallaxy that I think they're all being idiots.

JG is correct on this

Trump's Bad Sex Strategy | National Review

A calm explanation from Jonah Goldberg about the stupidity of the Trump, um, counter-grope strategy.

And it was probably written before he heard Trump basically tell a crowd that he wouldn't have forced himself on one of the women 'cos she's not hot enough (as Slate generously puts it.  Others would say - 'cos she's too ugly.)  (Mind you, if challenged on this, I bet he'll deny that's what he meant.  And absolutely no one will believe him.)

He is, genuinely, a rolled gold idiot.

Donald and "disgusting"

Two Women Say Donald Trump Touched Them Inappropriately - The New York Times: In a phone interview on Tuesday night, a highly agitated Mr. Trump denied every one of the women’s claims.

“None of this ever took place,” said Mr. Trump, who began shouting at the Times reporter who was questioning him. He said that The Times was making up the allegations to hurt him and that he would sue the news organization if it reported them.

“You are a disgusting human being,” he told the reporter as she questioned him about the women’s claims.

Asked whether he had ever done any of the kissing or groping that he had described on the recording, Mr. Trump was once again insistent: “I don’t do it. I don’t do it. It was locker room talk.”

There are, one strongly suspects, many more stories to come of unwelcome groping/kissing by Trump, and I wonder whether he'll find a new way to react other than by calling the reporter "a disgusting human being".

This seems to be his favourite insult, and in particular, he seems to use "disgusting" in contexts few other people would.  I take it as a sign of a pretty limited vocabulary, and it's hard to imagine him being good with words in diplomatically important encounters. 

Update:  Trump can't even take his own advice:

More on Penrose

I had missed that Peter Woit had favourably reviewed Roger Penrose's new book a few weeks ago.   Go have a read.

(It's interesting, the discussion about Penrose's issues with inflation.  I always had the feeling that this seemed to be a solution that was widely accepted before the mechanics of how it could happen were even guessed at, which seems to be a somewhat backwards way to work compared to most of physics.  Well, at least for a phenomena that isn't actually being observed but is being inferred. Was my hunch right?)

Watching for new craters

Seems the Moon still gets hit by meteors quite often:

Meteorites have punched at least 222 impact craters into the Moon's surface in the past 7 years. That’s 33% more than researchers expected, and suggests that future lunar astronauts may need to hunker down against incoming space rocks....

Although most of the craters dotting the Moon's surface formed millions of years ago, space rocks and debris continue to create fresh pockmarks. In 2011, a team led by Ingrid Daubar of NASA’s Jet Propulsion Laboratory in Pasadena, California, compared some of the first pictures taken by NASA’s Lunar Reconnaissance Orbiter (LRO), which launched in 2009, with decades-old images taken by the Apollo astronauts. The scientists spotted five fresh impact craters in the LRO images. Then, on two separate occasions in 2013, other astronomers using telescopes on Earth spotted bright flashes on the Moon; LRO later flew over those locations and photographed the freshly formed craters^{2, 3}.

LRO has taken about a million high-resolution images of the lunar surface, but only a fraction cover the same portion of terrain under the same lighting conditions at two different times. Speyerer’s team used a computer program to automatically analyse 14,092 of these paired images, looking for changes between the two. The 222 newfound craters are distributed randomly across the lunar surface, and range between 2 and 43 metres in diameter.

Why the Note 7 won't kill Samsung

Before I get onto this topic, has anyone else noticed that suddenly, at JB Hi Fi, the only tablets on sale are Samsung's and Apple's?  (And both of those companies have a small range now.)   Are other manufacturers giving up on tablets?   (I don't know that any other company had screens as good as the big two anyway, but I still liked looking at what other companies offered.)   Are large "phablets" killing the tablet market?

Back to the Note 7 explody phone:  the Note range was not that important to Samsung, anyway:

While the Note stylus is important to many users, it has still been a niche product. The last Note5 (there was no Note6) generated only 5% of all of Samsung's sales, Moorhead said. The Galaxy line of phones, including the Galaxy S7 and S7 Edge are from two to three times more popular, according to various accounts.

"The Note line has been very small for Samsung," he said. He and other analysts said it would be hard to see problems from the Note line affecting other lines.

"Samsung has many smartphone models globally and none have experienced the same problem," Burden said.

As to whether Apple or Huawei would benefit from the Note7 disaster, analysts were uniformly convinced there will be little boost to competitors.

Part of the reason is that Samsung already controls the largest share of the smartphone market globally, at 22% in the second quarter, according to IDC. Apple had 12% and Huawei had 9%.

"No way will Samsung lose its ranking over this problem," Moorhead said. "They are just so large."

I knew someone would have posted this theory before I could...

I had independently thought of this last week (honest), but kept forgetting to post about it. Anyway, I guessed it would have occurred to others - for all I know, someone on Reddit probably came up with it months ago.

It's the theory that anxiety about Trump has caused the killer clown panic:

The explanation for October's clown sighting hysteria is staring us in the face | Mary Valle | Opinion | The Guardian: I think this “clown epidemic” is a form of real-time trauma play. Right now, in this nation, on this planet, a bona fide human-like sociopath is very close to grabbing the One Ring of Power. Or the Former One Ring of Power that is Still Pretty Powerful.

China may be the Coke of today and we may just be the Pepsi, which may partially explain the second-rate, rinky-dink two-bit hustler who has fooled millions of people into thinking he somehow cares about them, courting steelworkers as he loads his buildings with Chinese steel, pretending to care about small business owners while notoriously stiffing them for decades.

Somewhere in their heads they must understand that they are not acting in their best interest, and this gigantic killer clown is using their despair and hopelessness against them by masterfully pulling their anger strings, turning them, too into ugly, disjointed residents of his angry uncanny valley.

Yes, it's a Jungian explanation, I suppose; in the same way he thought that UFOs were a sort of psychic projection of societal anxieties.
