In this study the scientists looked for evidence to support the
theory that genetic links exist between SSB and other characteristics
which carry benefits in one sex but not the other. Thus, SSB in one sex
could occur because genetically linked traits are favored by natural
selection in the opposite sex - the genetic tug of war.
The scientists based their hypothesis on the fact that most genes
are expressed in both males and females and often code for more than one
characteristic. For example, previous studies have reported that the
same genes that code for SSB are also the genes that code for mobility.
Mobility is known to be costly to female seed beetles as they do not
need to range as far as males to mate.
To test their hypothesis, the team of scientists selectively bred
male and female beetles to display increased SSB, studying how this
affected their mobility and reproductive success compared to beetles
that had been bred to display decreased SSB. The scientists showed that
when a particular sex had been bred for increased SSB, siblings of the
opposite sex enjoyed an increase in reproductive performance. They also
showed changes in traits such as mobility and sex recognition after
selective breeding on SSB, providing evidence for genetic links between
SSB and these traits across the sexes, according to the researchers.

Inside the world's largest cruise ship, Harmony of the Seas | Travel | The Guardian
There's no doubt about it, these massive new cruise ships look awesomely, um, massive, and are surely marvels of modern engineering.
The waterslides look a bit scary, though:
And I have two other reservations: the way these cabins look across the void straight into other cabins - not much privacy there without a closed curtain (although no doubt much better than being stuck in an windowless internal cabin):
And - I'm no marine engineer, but the whole ship looks a bit disturbingly top heavy, doesn't it?:
There's a hell of a lot of ship for a side on wind to blow against...

Dubious journalism continues
The Right is thrilled that a person who appeared on Q&A and made an entirely valid point about tax rate changes turns out now to have some pretty serious sounding criminal convictions, too.
I would have thought sensible people would at least have misgivings about national media giving front page treatment to this guy's past - is embarrassing a Liberal politician on the ABC enough grounds for the Murdoch press to do that? But, there is the aspect that an Q&A producer had (unwisely) referred to him as a "national hero" in a tweet, and the fact that lots of people promised money to him when they didn't know the full story. So I find it hard to say that his background is completely un-newsworthy; but surely it is still being handled disproportionately and with no regard to how it may affect Storrar and his family.
Of course, Storrar himself could help by, say, getting someone to agree to be trustee of the money on a trust set up for his daughter's education and benefit. That is, if any of the money promised now materialises.
And my complaint about Sinclair Davidson (who thinks the ABC should be running around investigating the private live of everyone who has ever appeared on Q&A) remains: he was calling this guy a "parasite" before any of this came out, and simply because he doesn't pay net tax.
Update: it's been decades since I have seen it, but the movie Absence of Malice just came to mind. I remember few details, except I'm sure it dealt with the journalistic ethics of printing stories that were technically newsworthy, but which carried a strong chance of "collateral damage" to people who were part of the story. (I only remember one scene, which must mean it was really effective - the poor woman who, I think, had had an abortion after an affair with a politician? running around the neighbourhood in the early morning, trying to pick up newspapers delivered on the front step before they could read them. I wonder if I have that right?) Pretty much the same goes here.
Update 2: I just checked the plot of the movie on Wikipedia - I was pretty close.

nest. Two or several females pool their litters in one nest and jointly
care for all offspring, even if litters differ by a few days in age. As
the females cannot tell apart between their own young and the offspring
of the other females, they indiscriminately nurse all pups in the
communal nest. If one female has more pups than the others, she invests
the same into nursing but weans more young and therefore has an
advantage.

Help! Our cash reserves only went up $150,000 last year!
I love the way the IPA makes a call for membership/donations when there's an issue they think can motivate the suckers sympathising readers to part with their cash.
The reality is, as I'm sure I've pointed out before, that the IPA already sits on a piggy bank of cash that's been increasing substantially over the last 5 years. Here, look at this page from their 2014/15 report:
Oh woe is them! Cash reserves have only increased $1.14 million over the last 5 years.
And for all of that, what did they get? A Liberal PM who made promises directly to them that he didn't keep. And even he's supporting the new PM in the superannuation changes the fight against which is supposed to be the rallying point for new membership.
If the IPA wants to run an advertising campaign supporting the ALP on this issue (lulz), why don't members (new or existing) tell them to use their growing cash reserves to cover it?

The Delusional Conservatives who pine for the return of Tony Abbott as PM must be feeling some dismay at his lengthy support for the Turnbull changes to superannuation in the budget.
More skepticism on company tax cuts
Election 2016: The weak case for a company tax cut
Oh, so it's not just Crikey and Bernard Keane arguing that the benefits of cuts to company tax aren't proven. Peter Martin now explains the reasons it might not be such a good idea, after all.
I find this issue confusing, partly because someone like Ken Henry, who was clearly perceived by some Right wing economists as being a soft headed friend of the Left, argued for it. But as Martin says today:

And earlier plans to cut company tax were to be at least partlyOn the matter of the "Google tax", I heard on Radio National this morning that (based on Britain's experience, which Turnbull is copying), it's not really expected to raise much tax of itself, rather it is designed to encourage companies not to minimise their tax by their offshoring profit methods. [Hence, it wouldn't do much to make up the loss in revenue that Martin explains today.]
funded by the companies themselves (Wayne Swan wanted to do it by
removing loopholes, the Henry review by a mining super-profit tax).
Turnbull's plan is different. It's give, without the take.
On the plus side he is cracking down on multinational tax avoidance, and to
some extent a lower company tax rate might itself make avoidance less
attractive.
The centrepiece of his election campaign is far more than a thought bubble. It derives from serious economic modelling. But it might not yet have been completely thought through.
Both sides take damage; but only one looks nasty
I didn't see Q&A on Monday night, but have been following the story about Mr Storrar, who argued that a tax change at the high end of the scale gives no benefit to people (like him, allegedly) with income at the bottom of the scale. Fair enough argument, one would have thought, but he did paint it in a very personal light.
I take it that Kelly O'Dwyer (who, in my opinion, used to come across as very hard nosed and an economic dry, but has softened somewhat since having a baby) didn't counter convincingly. Whereupon The Australian decided to follow up on Storrar's personal life not once, but two days running. Meanwhile, a unionist set up a donation site which has led to much money being promised to Storrar, most of it perhaps by people who may not have realised he didn't live with his daughters and (from today's Australian) has an adult son who is estranged from him, claims he led him into drug problems, and is annoyed at the positive image his father got from his TV appearance.
Even before this morning's story in The Australian, Sinclair Davidson at Catallaxy was angry at this guy's "sense of entitlement" and quoting passages from Atlas Shrugged(!) at him. In comments, he went as far as calling him a "parasite".
As far as I'm concerned, the whole incident demonstrates three things:
a. a certain gullibility on the Left to immediately accept appearances when it comes to "hard luck" stories;
b. the somewhat creepy way The Australian has sought to attack government critics personally, whether they be statutory appointments (Triggs) or mere audience members on an ABC show. Sure, they came up with the goods, so to speak, this time; and perhaps they would not have thought it worthwhile were it not for the donations being sought for him. But it still seems to me to have become an ugly, nasty paper, even with former editor Chris Mitchell leaving.
c. the nasty and poisonous taint of Randian name calling that is just under the surface of part of the Australian Right. That Sinclair Davidson, a man who seeks to be influential in Coalition policy, and is invited to talk at Liberal Party functions, should use "parasite" for someone who receives government benefits shows he has no idea how that language demeans himself in the eyes of the broader Australian public. The extreme and eccentric views of Ayn Rand have never caught on here like they have amongst a certain political corner of America, and in our more egalitarian society they are never likely to do so. As I have said before, the Liberals could only benefit by distancing themselves from the IPA, and him.*
So, I think both sides take some damage from this story, but only the Right ends up looking nasty.
* And why no ABC journalist ever questions him when he on TV or radio about statements he has made on his blog, but give him a clear run, is a bit of a puzzle. Perhaps they need me to supply links?

Intersex issues
The spectrum of sex development: Eric Vilain and the intersex controversy : Nature News & Comment
A somewhat interesting article here about an intersex researcher who has had his share of controversy.
Here's one part (in the first paragraph) that I thought surprising, if true:
A somewhat interesting article here about an intersex researcher who has had his share of controversy.
Here's one part (in the first paragraph) that I thought surprising, if true:
At Necker University Hospital for Sick Children in Paris in the
1980s, he says, doctors presumed that a child would be psychologically
damaged if he or she did not have normal-looking genitalia. In Vilain's
experience, that belief was so strong that doctors would take genital
abnormalities into account when deciding how hard to fight to save a
premature baby. “The unanimous feeling was that boys with a micropenis
could never achieve a normal life — that they were doomed,” he says.
(The paediatric-surgery department at Necker refused to answer questions
relating to past or current standards of care.)
DSDs occur in an estimated 1–2% of live births, and hundreds of genital
surgeries are performed on infants around the world every year1.
But there are no estimates as to how often a child's surgically
assigned sex ends up different from the gender they come to identify
with.

Packing Heat Onto College Campuses - The New York Times
Seems that there are a handful of sensible Republicans on guns: such as this one:
Seems that there are a handful of sensible Republicans on guns: such as this one:
The gun lobby’s relentless drive to arm students across the nation’sBut the best paragraphs of this article are at the end:
college campuses ran into an unexpected hitch in Georgia last week when
Gov. Nathan Deal vetoed a measure that would have let students carry
concealed weapons to class. Mr. Deal scoffed at the rationale of fellow
Republicans in the legislature that arming students would increase their
safety. “It is highly questionable that such would be the result,” he
stressed in his veto message.
And in July of next year, all six Kansas state universities and dozens of community colleges and tech schools must allow their students to carry concealed weapons on campus, classrooms
included. A poll of 20,000 Kansas college employees found 82 percent said they would feel less safe on an armed campus, according to National Public Radio. Two-thirds said the presence of guns would necessarily hamper their freedom to teach effectively. Critics of the move wonder, what if students get into a gun fight in class? And what happens to open discourse in a place tense with concealed carry?
The legislative majorities pushing this issue as a public safety necessity insist armed students and professors are the best way to defend against armed intruders. But a new study of federal firearms data indicates licensed and armed private citizens wind up harming themselves or others with their guns far more often than shooting attackers. The study by the Violence Policy Center, a gun safety advocacy group, found that over a three-year period ending in 2014, lessthan one percent of victims of attempted or completed crimes of violence used their firearms to try to stop crimes. The notion of quick-draw self defense remains a macho fantasy for gun buyers.

Legal cannabis and driving is a serious problem, after all
Fatal road crashes involving marijuana double after state legalizes drug: Foundation research also shows that legal limits for marijuana and driving are meaningless -- ScienceDaily
I always suspected that this would be a likely problem, but the evidence to show that it was really was seems to have been slow coming forward. And the thing is, because of the way THC works and hangs around for a long time at detectable levels, it's a tricky one to respond to. (Short of saying any THC in the test will result in a punishment, I guess.)
Update: here's a story about a recent case in Australia illustrating the difficulties of making "drug driving" laws for THC. I see that the Greens recommend following British laws where they also test for impairment - but I've always been doubtful about the reliability of roadside impairment testing.

So the IPA wants you to vote Labor? Ahahahaha
Disunity is meant to be death in politics, and surely the IPA's proposed campaign against the Coalition's superannuation changes is only going to hurt Turnbull and his government in this election.
Now, some might say that the sight of a think tank campaigning on the grounds "but think of the rich...the poor mistreated rich!" might actually encourage swing voters who might have leant towards Labor to go for Turnbull after all; but I can't see it working that way. No, I think the effect will be more along the lines that they won't vote for the side of politics which the rich think they can push around to get changes back in their favour.
It's early days, but I suspect the Coalition must be feeling pretty nervous about the way this election campaign is going so far.

Good quotes
John Quiggin has posted quotes from Jennifer Rubin (herself a conservative) writing at the Washington Post about the need for conservative politics in the US to reform itself, and I have to agree with JQ that they are very, very sensible:
Somewhere in that mix are the contours of a platform that is contemporary and conservative and for which there is arguably a broader demographic and geographic appeal. It should not include (for there is no political appetite for these things, and they are unattainable and/or unwise from a policy standpoint): opposition to gay rights; large tax cuts for the rich; protectionism; expelling women from combat in a volunteer army; rooting gays out of the military; obsessing over bathroom assignments; fixating on local ordinances about wedding services; keeping the status quo on entitlements; cutting out (as opposed to reforming) the safety net; never, ever raising taxes on anyone; and mass deportation.
What follows will be different from 1980s conservatism because we are more than three decades removed from Ronald Reagan. Our problems are different — stagnant wages, resurgent and varied enemies, the withering of communal organizations, crumbling infrastructure. We have recognized that the old solutions — a rising tide lifts all boats (not if you have no skills) — are insufficient. However, Republicans should not sell snake oil. Telling working-class whites that the problem is immigrants is a lie. The economic data overwhelmingly show that immigration spurs growth, creates jobs and aids innovation, and no amount of junk statistics from zero-population Malthusians is going to change this. (There are solutions for the tiny segment of the workforce, usually the last wave of immigrants, that might be adversely affected.) Telling workers that millions of jobs went to China is a lie, too. The problems are real, and the solutions must be real as well. We need the world’s best and brightest workers, a humane society and methods to control borders and prevent visa overstays.
Along with all of this, conservatives have to end their intellectual isolation and self-delusions. They need to stop pretending that climate change is not occurring (the extent and the proposed solutions can be rationally discussed) or imagining that there is a market for pre-New-Deal-size government. Conservatives must end their infatuation with phony news, crank conspiracy theories, demonization of well-meaning leaders and mean rhetoric. It’s time to grow up, turn off Sean Hannity, get off toxic social media and start learning about the world as it is. (Read a book authored by someone without a talk show, spend time with non-Republicans, take an online course in economics.) Confirmation bias has become pathological.
Good marks for effort..sort of
Thai university students caught using spy cameras, smartwatches to cheat on medicine exam
Of more general interest in the report is the explanation that the Thai education system is not doing so well:
Three students used glasses with wireless cameras embedded in their frames to transmit images to a group of as yet unnamed people, who then sent the answers to the smartwatches.
Mr Arthit said the trio had paid 800,000 baht ($31,000) each to the tutor group for the equipment and the answers.
"The team did it in real-time," Mr Arthit wrote.
In the 2014 PISA rankings, which measures global educational standards, Thai students performed below the global average and much worse than those from poorer Vietnam in subjects like maths and science.
Last year, the World Bank said improving poor quality education was the most important step the kingdom could take to securing a better future, with one third of Thai 15-year-olds "functionally illiterate" — lacking the basic reading skills to manage their lives in the modern world.
Critics say the kingdom's high corruption levels and ongoing political instability has made deep-seated education reforms impossible over the last decade.
