A round up of interesting articles and posts that I have come across the last couple of weeks.

400-year-old Greenland shark is oldest vertebrate animal

The Guardian article is about the newest research into the Greenland shark which indicates that they have a lifespan of centuries, and might be the oldest vertebrate animals around. The scientists did this by looking at the carbon-14 in the eyes of some captured sharks, and used this to estimate the ages of the specimens. This is obviously imprecise, but it does clearly indicate that the sharks have been around for a long time.

As a side note, this article can’t help remind of the old story about the bowhead whale swimming around with a 100-year old harpoon fragment embedded in it.

 

In other marine news, it appears that humpback whales protect potential prey from Orcas, even when the prey is of entirely different species, such as seals.

Humpback whales interfering when mammal-eating killer whales attack other species: Mobbing behavior and interspecific altruism?

Humpback whales (Megaptera novaeangliae) are known to interfere with attacking killer whales (Orcinus orca). To investigate why, we reviewed accounts of 115 interactions between them. Humpbacks initiated the majority of interactions (57% vs. 43%; n = 72), although the killer whales were almost exclusively mammal-eating forms (MEKWs, 95%) vs. fish-eaters (5%; n = 108). When MEKWs approached humpbacks (n = 27), they attacked 85% of the time and targeted only calves. When humpbacks approached killer whales (n = 41), 93% were MEKWs, and ≥87% of them were attacking or feeding on prey at the time. When humpbacks interacted with attacking MEKWs, 11% of the prey were humpbacks and 89% comprised 10 other species, including three cetaceans, six pinnipeds, and one teleost fish. Approaching humpbacks often harassed attacking MEKWs (≥55% of 56 interactions), regardless of the prey species, which we argue was mobbing behavior. Humpback mobbing sometimes allowed MEKW prey, including nonhumpbacks, to escape. We suggest that humpbacks initially responded to vocalizations of attacking MEKWs without knowing the prey species targeted. Although reciprocity or kin selection might explain communal defense of conspecific calves, there was no apparent benefit to humpbacks continuing to interfere when other species were being attacked. Interspecific altruism, even if unintentional, could not be ruled out.

Nation Geographic has a good write up about this: Why Humpback Whales Protect Other Animals From Killer Whales

 

In completely unrelated news, it appears that better health coverage makes people more healthy. Hardly a surprising information, but there are now actual data to back this common-sense conclusion up.

Obamacare Appears to Be Making People Healthier

A few recent studies suggest that people have become less likely to have medical debt or to postpone care because of cost. They are also more likely to have a regular doctor and to be getting preventive health services like vaccines and cancer screenings. A new study, published Monday in JAMA Internal Medicine, offers another way of looking at the issue. Low-income people in Arkansas and Kentucky, which expanded Medicaid insurance to everyone below a certain income threshold, appear to be healthier than their peers in Texas, which did not expand.

It seems incredible that it is necessary to collect data about this, when it is so obvious that it would be the case. There are, however, many things that appears obvious, which turns out to be wrong, so it is good that the researchers uses this opportunity to find data to expand our knowledge.

 

Jennifer Raff has written a very interesting post about human cannibalism:

Cannibalism and Human Evolution

The post starts out with the following bit of family story:

One of my aunts was once asked during an interview for a position in the criminal justice field “Is there any kind of criminal you don’t feel you could work with?”

“Yes,” she replied. “Have you ever seen ‘The Silence of the Lambs?’ I don’t do cannibals.”

This reminds me of a story I was once told by an elderly lady from New Zealand, who told about back when she went to school, and one of her teachers explained to the class that people used to be cannibals, but that this no longer was the case, and that they of course don’t know what humans taste like, to which a Maori girl in the class put her hand in the air, and said, “excuse me miss, it tastes like chicken”.

The girl, who almost certainly didn’t have any firsthand knowledge of this, didn’t make any friends in the class.

There certainly is a strong taboo surrounding cannibalism. Probably especially so when you are in areas where it has been practiced within the last couple of centuries.

 

ThinkProgress has a good article on John Lott, a pro-gun “scientist” who is actually a fraud:

The NRA’s Favorite Gun “Academic” Is A Fraud

The United States seems to be in a perpetual cycle mourning mass shootings in the country. This year alone, there have already been 233 mass shootings, where four or more victims were shot, leaving 310 dead and 930 injured. But every time another shooting happens, advocates pop up arguing that more guns don’t actually lead to more violence and stall the much-needed conversation about gun control.

John Lott is, if not the most influential, certainly the most prolific “academic” in the gun debate. He has authored weekly columns in local newspapers on the horrors of gun free zones, published widely-distributed books on the ostensible benefits of right-to-carry laws, and his newest book The War on Guns has received rave reviews by prominent conservatives, like Sen. Ted Cruz (R-TX), Sen. Marco Rubio (R-FL), and Newt Gingrich.

I had missed the fact that John Lott had turned up again like a bad penny.

As the ThinkProgress article explains, John Lott lies and distorts gun statistics, makes undocumented claims, lies about his data and research, and has been caught sockpuppeting both book reviews and comments to articles and blogposts.

Tim Lambert at Deltoid has done a lot of work debunking John Lott’s stuff in the past.

A few links to interesting stuff that I have come across.

The evidence shows that chiropractors do more harm than good

Chiropractors rely heavily on manipulating their patients’ spines, and the benefits are not at all clear. Practitioners usually insist that their manipulations are effective for a bafflingly wide range of conditions. On the internet, for instance, it is hard to find an illness that chiropractors do not claim to cure. However, the published evidence generally reveals these claims to be little more than wishful thinking. Therefore, even relatively minor side-effects might tilt the risk/benefit balance into the negative.

There is now a lot of evidence showing that more than half of all patients suffer mild to moderate adverse effects after seeing a chiropractor. These are mostly local and referred pains that usually last for two to three days. Chiropractors often claim that these are necessary steps on the road to getting better. On a good day, we might even believe them.

But unfortunately there is more, much more. Several hundred cases have been documented in which patients were seriously and often permanently damaged after chiropractic manipulations.

The news is not surprising for anyone who has looked into the subject, but the numbers are truly alarming.

People are spreading dangerous lies about an invention that prevents millions of illness every year

Yet another post about the dangers of anti-vaccination. It is good, but I hate the fact that we have to keep writing this stuff.

David Neiwert has writte a great series of posts in “celebration” of Confederate Heritage Month, the latest is Confederate Heritage Month: The Strange Fruit That Fed Jim Crow.

If blacks’ slave status largely protected them from racial violence before the Civil War, then its abolition also left them remarkably vulnerable to such assaults upon the South’s defeat. Certainly, once emancipated, they became seen as a real threat to whites, and particularly to their dominant status; much of this perception, particularly regarding the violent nature of the newly freed blacks, as we shall see, was more an illusion produced by psychological projection than real in any meaningful way.

This became immediately manifest, during Reconstruction, when black freedmen were subjected to a litany of attacks at the hands of their former owners that went utterly unpunished. As documented by Philip Dray in his definitive study, At the Hands of Persons Unknown: The Lynching of Black America, these crimes turned up in hospital records and field reports from the federal Freedmen’s Bureau, all of which described a variety of clubbings, scalpings, mutilations, hangings and even immolations of former slaves, all within the first year after Appomattox.

Ads force German xenophobes to hear the plights of refugees

People searching for anti-immigrant YouTube videos in Germany are going to have an awkward time doing so thanks to a novel advertising campaign by Refugees Welcome. The organization has put together a series of 30-second spots featuring real refugees who discuss their situations using a potent mixture of perspective, fact and humor to counter the country’s rising xenophobic tide.

Finally a good use for those unskippable ads on YouTube.

How to Explain Mansplaining

It was on a recent trip to Indonesia that, as a male bureaucrat sounded forth on a vast span of subjects without being asked to do so, I realized that the English language was in need of a new addition: the manologue. This otherwise perfectly charming man droned on and on, issuing a steady stream of words as I sat cramped in a tiny room with a group of fellow journalists and squinted at the labels on the soda cans hospitably placed on a table in front of us.

No, Obama doesn’t hold a “grudge” over Britain torturing his Kenyan grandfather. But so what if he did?

[W]hen Obama is accused of bearing an “anti-colonial” grudge, it is typically framed as irrational, often implied to be racial, or made alongside an accusation that he secretly hates America. “Anti-colonial” has become a kind of dog-whistle, and at times a racist one.

Why? Why is this possibility — that Obama might mind that his grandfather was wrongly and unapologetically tortured — so taboo that it is raised only as part of an often-racist dog-whistle?

…

President Obama is not the first head of state to do business with countries that mistreated his ancestors. But, frequently, it is assumed that those heads of state will bring that history with them — and that doing so is acceptable, even appropriate.

Former Polish President Lech Kaczynski and his brother, former Prime Minister Jaroslaw Kaczynski, often spoke of their father’s role in the 1944 Warsaw Uprising against Nazi rule, which biographers tend to describe — always in positive terms — as formative for how they led Poland.

A good article on the double standard on whether one should remember past wrongs or not.

Lazy linking

I am fairly busy until some time after Easter, so don’t expect neither massive blogging nor a banner from me until then. In the meanwhile, here are some links to articles, blogposts etc. that I think are worth reading.

As Women Take Over a Male-Dominated Field, the Pay Drops

A new study from researchers at Cornell University found that the difference between the occupations and industries in which men and women work has recently become the single largest cause of the gender pay gap, accounting for more than half of it. In fact, another study shows, when women enter fields in greater numbers, pay declines — for the very same jobs that more men were doing before.

This is something which has been suspected for a long time (with earlier studies indicating the same), but it is good to have new studies demonstrating it. This means that men can’t just dismiss the pay-gap as a symptom of different career choices. I will probably blog more about this study at some stage.

Hillary Clinton is funding congressional races so she can enter White House with a majority

One of the most intriguing storylines of the 2016 election has turned out to be one of the most underreported. Every candidate for President hopes to not only enter the White House, but do so with a congressional majority in hand. Although Hillary Clinton is the clear frontrunner and is likely to win the election, republican gerrymandering means that her odds of having a democratic House and Senate are questionable. But she’s spent the past six months trying to rectify that by essentially funding the congressional races of 2016 democratic candidates herself.

This seems like a very smart move. If there is one thing that the GOP has shown us under the Obama presidency, it is that they are not going to work with a Democratic president. This means that it is important to get as many Democrats into the congress as possible. This is a sound tactic, no matter who wins the Democratic primary, and if the GOP should somehow win the presidential race, it is vital that the Democrats hold real power in congress (a note: comments about democratic candidates and the merits of the one or another are not welcome, and will be deleted – I am not interested in getting my blog involved in the internal politics of the democratic party).

One more time: Vaccine refusal endangers everyone, not just the unvaccinated

One of the more frequent claims of antivaccine activists often comes in the form of a disingenuous question. Well, maybe it’s not entirely disingenuous, given that many antivaccinationists seem to believe premise behind it. The question usually takes a form something like, “If your child is vaccinated, why are you worried about my children? They don’t pose any danger to you.” Of course, the premise behind that question is, ironically, one that conflicts with many of the beliefs behind antivaccinationism, in particular the belief that vaccines are ineffective. Yet, the premise behind this question is that vaccines are so effective that there’s no reason for the parents of a vaccinated child to be concerned if that child comes in contact with another child with a vaccine-preventable disease. Of course, no one ever accused antivaccine activists of being consistent in their beliefs.

Once again, Orac does great work taking on the anti-vaccination crowd and their claims.

Bahrain must immediately release Zainab Al-Khawaja

Index on Censorship calls for the immediate release of human rights activist Zainab Al-Khawaja, who was arrested on Monday 14 March 2016 with her one-year-old son Abdulhadi.

“Zainab Al-Khawaja is facing retaliation for exercising her right to freedom of expression,” said Index’s senior advocacy officer Melody Patry. “Bahraini authorities have been harassing her and her family for years and this arrest — based on absurd charges — further shows Bahrain’s determination to silence its critics.”

I stand fully behind the call from Index on Censorship, and hope that the US, the EU and the rest of the democratic world will put pressure on the Bahraini authorities for the release of Zainab Al-Khawaja and other jailed critics.

Four words that might break my brain: “Black, gay Trump supporter”

I think most of us are with Tony on this one.

Change in suicide rates in Switzerland before and after firearm restriction resulting from the 2003 “Army XXI” reform

Abstract

OBJECTIVE:

Firearms are the most common method of suicide among young men in Switzerland. From March 2003 through February 2004, the number of Swiss soldiers was halved as a result of an army reform (Army XXI), leading to a decrease in the availability of guns nationwide. The authors investigated the patterns of the overall suicide rate and the firearm suicide rate before and after the reform.

METHOD:

Using a naturalistic study design, the authors compared suicide rates before (1995–2003) and after the intervention (2004–2008) in the affected population (men ages 18–43) and in two comparison groups (women ages 18–44 and men ages 44–53). Data were received from the Swiss Federal Statistical Office. Interrupted time series analysis was used to control for preexisting temporal trends. Alternative methods (Poisson regression, autocorrelation analysis, and surrogate data tests) were used to check validity.

RESULTS:

The authors found a reduction in both the overall suicide rate and the firearm suicide rate after the Army XXI reform. No significant increases were found for other suicide methods overall. An increase in railway suicides was observed. It was estimated that 22% of the reduction in firearm suicides was substituted by other suicide methods. The attenuation of the suicide rate was not compensated for during the follow-up years. Neither of the comparison groups showed statistically significant changes in firearm suicide rate and overall suicide rate.

CONCLUSIONS:

The restriction of firearm availability in Switzerland resulting from the Army XXI reform was followed by an enduring decrease in the general suicide rate.

I couldn’t really see a way to include it in my last post about Swiss gun laws, but it is an interesting study, which shows limiting access to guns will lead to a decrease in suicides.

The delusion of immortality

Imagine all the poor transhumanists who were born in the 19th century. They would have been fantasizing about all the rapid transformations in their society, and blithely extrapolating forward. Why, in a few years, we’ll all have steam boilers surgically implanted in our bellies, and our diet will include a daily lump of coal! Canals will be dug everywhere, and you’ll be able to commute to work in your very own personal battleship! There will be ubiquitous telegraphy, and we’ll have tin hats that you can plug into cords hanging from the ceiling in your local coffeeshop, and get Morse code tapped directly onto your skull!

Alas, they didn’t have a Ray Kurzweil or Aubrey deGray to con them with absurd exaggerations.

If it isn’t clear, PZ Myers is not the greatest fan of transhumanism and the ideas pushed by people like Kurzweil. I am completely in agreement with him on this.
