This is … er … a lede:

Here’s a horrifying little story to kick off your weekend: A 16-year-old girl in Japan recently had a tumor surgically removed from her ovary β€” and when her doctors split it open, they found a tiny brain growing inside.

Or, you know, as the headline from Science of Us explained, “Doctors Found a Tiny Second Brain Growing Inside This Woman’s Tumor”.

A Trivial Question About Your Coffee Cup

A coffee cup at Terra Vista. Detail of photo by B. D. Hilling, 2013.

Cari Romm explains, for Science of Us, a few details about why “It’s Okay to Never Wash Your Coffee Mug”:

As Heidi Mitchell wrote in a recent Wall Street Journal column, it’s fine to never wash your mug, as long as you’re not sharing it with anybody else. Better than fine, in fact: It may actually be the most sanitary option.

There are two caveats to that statement, infectious-disease expert Jeffrey Starke, a pediatrics professor at Baylor College of Medicine, told Mitchell: One, it only applies if you’re not sharing the mug with anybody else. And two, “if you leave cream or sugar in your mug over the weekend, that can certainly cause mold to grow”―in which case, wash it out.

The bottom line, Romm suggests, is that “letting your mug live in its own filth may be a safer bet than the alternative: scrubbing it with the disgusting communal sponge in the office kitchen”.

And, yes, there is the bit about putting the sponge in the microwave, but this still begs a question.

Who says you absolutely must use a sponge?

A Note re: Kaine vs. Pence

22 FEBRUARY 2015: Indiana Gov. Mike Pence appears on 'FOX News Sunday with Chris Wallace'. Guest host John Roberts interviewed Mr. Pence regarding various issues, including his status as a 2016 'dark horse' for the GOP presidential nomination, and the Hoosier State's 'religious freedom' bill empowering discrimination, which Pence signed into law in late March. (Image credit: FOX News)

This is important:

In one important area, Pence has the advantage of being perceived as a mainstream pol. Politico published a piece yesterday that characterized tonight’s vice presidential debate as “Battle of the Normals,” and a “sane moment” in a campaign cycle that’s often seemed insane.

On a certain level, I can appreciate where analysis like this is coming from. As a matter of tone and temperament, Mike Pence is hardly scary: the governor is a mild-mannered, soft-spoken Midwesterner. Unlike the man at the top of the GOP ticket, no one would ever expect Pence to start tweeting at 3 a.m. about his disgust for a beauty-pageant contestant and encourage Americans to seek out a “sex tape.”

But to shift one’s focus from tone to policy is to see one of the most extremist politicians to seek national office in over a generation.

Steve Benen is not wrong. This has been a factor worth considering in recent years, and even more so this cycle. What counts as centrist or mainstream is, in American politics, a roving range. The msnbc blogger and producer continues:

About four years ago, Nate Silver published an interesting analysis of Paul Ryan, who’d just been named to Mitt Romney’s ticket. Nate wrote at the time, “Various statistical measures of Mr. Ryan peg him as being quite conservative. Based on his Congressional voting record, for instance, the statistical system DW-Nominate evaluates him as being roughly as conservative as Representative Michele Bachmann of Minnesota. By this measure, in fact, which rates members of the House and Senate throughout different time periods on a common ideology scale, Mr. Ryan is the most conservative Republican member of Congress to be picked for the vice-presidential slot since at least 1900.”

Nate added a chart, highlighting the fact that Ryan’s record put him slightly to the right of Dick Cheney, who was slightly to the right of Dan Quayle.

There are curious circumstances, now and again, in which the GOP hardliners leave me standing shoulder to shoulder with Republicans I generally wouldn’t get along with. George W. Bush on China, and suddenly I’m commiserating with Pat Buchanan? What was it, Jade Helm? How do Rick Perry and I land on the same side? I can tell you, though, that when Lindsey Graham is bagging points off John Kasich being described as a “moderate”, well, at least we have that much in common.

It happens.

We revisit the question for Mike Pence. Benen notes the Indiana governor also has a record in Congress:

In the 107th Congress (Pence’s first, covering 2001 and 2002), for example, out of 435 members of the U.S. House, Pence ranked #428―meaning that 427 members were to his left, putting the Hoosier on the far-right-wing fringe. The results were roughly the same in the 108th Congress and the 109th.

By the 110th Congress, Pence was at #432, putting him to the right of nearly everyone in the chamber. The results were roughly the same in the 111th Congress and the 112th.

Let’s put this another way: during his congressional career, Pence wasn’t just more conservative than Paul Ryan. His voting record also put him to the right of Michele Bachmann, Todd Akin, Steve King, and even Louie Gohmert. That’s not an exaggeration. Bachmann, Akin, King, and Gohmert all had voting records less extreme than Mike Pence.

The problem is the gap between perceptions of Mike Pence and his actual record. To use Politico’s phrasing, the Hoosier is seen as “normal” and “conventional.” But on a substantive level, we’re talking about a politician whose claim to fame is an anti-LGBT law that did real harm to his state. Pence is a climate denier. He rejects the idea that cigarettes are deadly. He doesn’t believe in evolutionary biology, but he does support “conversion therapy.”

There was an embarrassing episode having to do with alleged Iraqi WMDs; something about privatizing Social Security not being conservative enough; something about government shutdowns; oh, right, and some manner of conspiracy theory about Disney film and women in the military.

Unfortunately, that last isn’t a joke.

This is the problem: If Gov. Mike Pence is “normal”, then we might pause to consider how we define normalcy.

Your Lede of the Day (Antibacterial)

This is the flabbergasting, unexpected lede of the day:

The Food and Drug Administration said today that antibacterial soaps and body washes will be banned starting next year. The FDA says they aren’t any more effective than regular soap and manufacturers have been unable to prove that they’re safe for long-term use.

(Rinkunas)

Science of UsAlright, then. I mean, you know: It’s time? Okay.

It’s just one of those things we hear about but don’t expect to happen.

Clear as Wood

Two fun paragraphs:

Researchers at the University of Maryland were able pull away color and chemicals from a block of wood to leave it impressively see-through. The result is a material that is both stronger and more insulating than glass, with better biodegradability than plastic. “We were very surprised by how transparent it could go,” said Liangbing Hu, who wrote about the project in Advanced Materials.

Hu’s team isn’t the only group that’s developed a technique for transparent wood―Swedish researchers have also been able to clear out that pesky visible pulp, replacing it with a transparent polymer. The treatment techniques appear pretty similar: it’s a two-stage process.

The human species never ceases to amaze me.

The trees, of course, are appalled.

Something Completely Different

Shizuo Heiwajima wanders Ikebukuro. (Detail of frame from Durarara!! episode 7, "Bad-Ass Dude".)

“Have to face it, I’m finally an addict; the smell of popcorn and worn plush lingers for weeks.”

―Margaret Atwood

Here’s a change of pace:

No matter where you go, the movie theaters tend to smell the same: like popcorn, and the butter-like stuff they put on the popcorn, and that stale odor of recycled air-conditioned air.

Also fear, and sadness, and joy. These feelings aren’t scents, per se, in that you don’t take a whiff of air and consciously think, “Man, it smells scary in here.” But in a study published earlier this week in the journal Nature, a team of researchers found that the air in movie theaters tends to take on unique chemical signatures based on how the audience reacts to what’s happening on the screen. A horror film, for instance, will have a different chemical imprint than a comedy, which will leave a different mark than a tearjerker.

The report from Cari Romm for Science of Us actually sets a number of thoughts in motion, including a weirdly recursive context in which yes, actually people do now have ideas of something smelling scary, and as the colloquialism sets roots in American culture the idea will eventually concretize or crystallize long enough to be noted, and then set right back to shifting and changing and growing and evolving. It’s not quite the same as the decade-old debate whether sour apple or lime tastes like green, though even then the question illustrates contextual challenges. To wit, the straightforward answer: I’m middle-aged; the sour-apple thing is “new” by comparison, so “lime” is what tastes like “green”. A more honest answer: Marijuana. A more cultural-contextually useful answer: I’m sure as a middle-aged lifer in cedar and hemlock country, green means something different to me than it would a young’n barely as tall as the wheat that is all he can see for miles in any direction.

Smells, of course, are more interesting, but translating the relevant trivia about memory into something useful seems a challenging return on investment especially according to a daunting prospect against success.

Nor should we wonder why Atwood comes to mind.

None of My Business

Detail of FLCL episode 3, 'Marquis de Carabas'.

Do what you’re gonna do: Roll your eyes, groan, gnash your teeth, bang your head on the desk, throw your hands and declare, “I could have guessed that!”

If you happen to be a woman interested in taking Addyi, the first FDA-approved drug intended to treat low libido in women, your doctor will first tell you this: You absolutely cannot drink β€” at all β€” as long as you’re taking the drug, because alcohol has been shown to exacerbate its side effects, including fainting, dizziness, and low blood pressure. When the drug hits the market in mid-October, it will come with a black box underlining the importance of abstaining from alcohol while taking the medication.

But here’s the thing. Nobody actually even knows what would happen if a woman taking Addyi were to cheat and have, say, a glass of wine with dinner β€” because the research on the effects of drinking while on the medication was done almost entirely on men. The alcohol-safety study included 23 men, and a grand total of two women.

Okay, so: The good news is that there is a reason this happens, and it is perfectly understandable. The bad news is that this doesn’t actually help anything, and thus doesn’t count as good news.

Worth a Few Minutes of Your Time

Suou's Reflection: Detail of frame from Darker Than Black: Gemini of the Meteor.

This is worth keeping an eye on:

Few recent books have spawned as many arguments as Sheryl Sandberg’s Lean In. Until last week, though, I hadn’t seen anyone claim that Sandberg’s feminism-in-the-workplace manifesto is anti-science. And yet that’s exactly what Amy Alkon, an advice columnist who frequently dips into psychological research, argued in the New York Observer on Friday.

Drawing on evolutionary psychology β€” basically, the idea that many of our behavioral tendencies were shaped long ago, when the sorts of pressures that needed to be overcome in order to survive and reproduce were a lot different than they are today β€” Alkon writes that Sandberg simply ignores fundamental, biologically, and genetically predetermined differences between male and female behavior, and that because of these differences, Sandberg’s advice could actually be harmful if followed.

This sort of thing pops up from time to time β€” it’s not uncommon to see pop-science accounts that use evo-psych to make sweeping statements about human nature, particularly on gender issues. In one recent incident Science of Us readers might remember, for instance, researchers used evo-psych principles to tell a rather nonsensical story about why Kim Kardashian’s butt appeals to so many men. But Alkon’s column, even if it draws on some long-standing and stale claims about the differences between men and women, deserves a thorough debunking simply because it’s such an egregious example of the subgenre.

Jesse Singal of New York magazine’s Science of Us blog offers the well-considered response to one of those strange defenses of sexism that starts with the premise that “women are meeker than men, and less likely than men to bond, friendship-wise, with members of the same gender β€” behaviors forged by, you guessed it, evolution”.

And Singal really does deserve some credit for patience; repeatedly dismantling these arguments does nothing to prevent them from popping up again, but this is also the sort of thing people can steel themselves against for the future; and once one learns the familiar patterns, one is well equipped to respond to this nonsense when it arises in personal circles. The thing is that being polite does not mean sitting back and letting your friends embarrass themselves and denigrate others blindly pushing this sort of stuff. The number of advocates who, when challenged, resent the suggestion of misogyny suggests blithe ignorance, lest we have grossly underestimated the will while focusing on the habit.

And, frankly, that latter is a bit unsettling; this isn’t really some sort of conscious calculation so many people make in such a way that it looks like a conspiracy. This is just people being people. But that’s the thing: We can attempt to politely correct the record, and if it really is that big a deal to one of our friends, well, yeah, good luck with that. No, really, I can’t tell you to leave them behind; neither can I suggest you are remotely obligated to stick around.

But it seems somehow improper to leave them to wallow in potentially contagious ignorance. Indeed, we might even suggest it is dangerous. The thing is that this comes up enough that it would probably be helpful to have a response at hand. For now, Singal’s is pretty useful.
