Both a fascinating human story and an example of the complexity of biology.

SREBP1 has long been known to manage fat storage. After a meal, SREBP1 is helping each of your cells decide whether to use the fat that just arrived for fuel or store it for later.
Lefai’s team found, in animals, that a buildup of SREBP1 in the cell can lead either to extreme muscle atrophy or extreme muscle growth. And that was something Jill was interested in. She sent Lefai a two-line email with a question about his work. He thought it was from a scientist or Ph.D. student and responded.
Soon, Jill told Lefai about her own history, and suggested that it is possible that he discovered the actual biological mechanism that makes her and Priscilla so different — SREBP1 interacting with lamin.
How a woman whose muscles disappeared discovered she shared a disease with a muscle-bound Olympic medalist.

A lovely essay about bad coffee.
Lately, something has changed. Lately, I've been reacting to fancy coffee the same way a child reacts to an accidental sip of red wine mistaken for grape juice. I don't know when it happened, but I've devolved into an unexpected love affair with bad coffee. It's not just instant coffee that I hanker for each morning, either, it's any subpar coffee I can get my hands on.

Getting past the "information" level, there's some greatness to things like, " The best cup of coffee I ever had was the dirty Viennese blend my teenage friends and I would sip out of chipped ceramic mugs at a cafe near the University of Cincinnati while smoking clove cigarettes and listening to Sisters of Mercy records, imagining what it would be like to be older than we were." and " On top of the refrigerator, my old friend the French press has gathered dust. When I notice a dead housefly decomposing inside it, I wonder what the hell has happened to me."

In fact, pasta itself is probably the most famous example of this sort of cultural appropriation. It was originally a failed Italian attempt to copy Chinese noodles (as is Japanese ramen, actually). Aren't you glad we have pasta? Aren't you glad we have ramen? You can thank cultural appropriation.

In France, pleasure, or “plaisir,” is not a dirty word. It’s not considered hedonistic to pursue pleasure. Perhaps a better translation of the word is “enjoyment” or even “delight.” Pleasure, in fact, takes the weight of a moral value, because according to the French, pleasure serves as a compass guiding people in their actions. And parents begin teaching their children from very early childhood in a process called the education of taste, or “l’éducation du gout.”
If New Year's resolutions have you in an abstemious mindset when it comes to enjoyment these days, consider a pleasure recalibration based on 'l'éducation du gout.'

You can never find evidence to prove a hypothesis (or theory) true, but just whether that hypothesis (or theory) is consistent with the data or the facts. For that purpose in this particular case, you may try to check 

1. whether the lower socio-economic class is relatively more fertile in the US (compared to the rest of the US population) than in other developed countries, and 
2. whether a lower IQ score is correlated with lower socio-economic status:


«You hear about the "haves" versus the "have-nots," but not so much about the "have-one-or-nones" versus the "have-a-fews." This, though, is how you might characterize the stark and growing fertility class divide in the United States. Two new studies bring the contrasting reproductive profiles of rich and poor women into sharp relief. One, from the Guttmacher Institute, shows that the rates of unplanned pregnancies and births among poor women now dwarf the fertility rates of wealthier women, and finds that the gap between the two groups has widened significantly over the past five years. The other, by the Center for Work-Life Policy, documents rates of childlessness among corporate professional women that are higher than the childlessness rates of some European countries experiencing fertility crises.

Childlessness has increased across most demographic groups but is still highest among professionals. Indeed, according to an analysis of census data conducted by the Pew Research Center, about one quarter of all women with bachelor's degrees and higher in the United States wind up childless. (As Pew notes, for women with higher degrees, that number is actually slightly lower than it was in the early 1990s—but it is still very high.) By comparison, in England, which has one of the highest percentages of women without children in the world, 22 percent of all women are childless. According to the new Center for Work-Life Policy study, 43 percent of the women in their sample of corporate professionals between the ages of 33 and 46 were childless. The rate of childlessness among the Asian American professional women in the study was a staggering 53 percent.

At the same time, the numbers of both unplanned pregnancies and births among poor women have climbed steadily in recent years. About half of all pregnancies in this country are unplanned, with poor women now five times more likely than higher-income women to have an unplanned pregnancy, and six times more likely to have an unplanned birth, according to the Guttmacher Institute's recent analysis of government data. »

Here you are:

«Inferring from the evidence on declining fertility differentials, the question arises as of whether status differentials will converge. Of particular interest is to which extent education will continue to negatively affect fertility in the coming years. For Norwegians born 1935-58, cohort fertility for women with advanced tertiary degrees fell from 2.1 to 1.9 children while for those with primary school, it fell from 2.5 to 2.1, narrowing the education-fertility gap from 0.4 to 0.2 children. However, during the last few recent decades in Belgium, Sweden, Germany and Japan, the fertility gap between high and low educated has not converged (Björklund 2006, Retherford et al. 2004). Moreover, in the US 1960-1990 the gap between college and non-college educated women widened from 0.3 to 0.5 children as TFR fell from 3.7 to 2.1 children (Statistical abstract of the United States 2001, Yang and Morgan 2003). On the basis of data from 57 less developed countries, Bongaarts and Menken (1983) suggests that even where fertility approaches replacement levels, the tertiary educated will continue to have low fertility as the more educated still prefer smaller families.»

— Skirbekk V. Fertility trends by social status. Demographic Research (2008) vol. 18 (5) pp. 145-180
demographic-research.org/Volumes/Vol18/5 

Norway (1958 cohort fertility):
2.1/1.9 ≈ 1.105
US (1990 fertility rate):
>2.6/2.1 ≈ 1.238

Thus, for the most recent cohort (1958), the Norwegian women with lower education level (which is in turn correlated with lower socio-economic status) were on average 11% more fertile than those with higher education level, whereas for the fertility rate of the most recent year (1990), the American women of the lower education level were on average >24% more fertile than their higher educated counterparts.


Correlation between IQ scores and future life outcomes (e.g., later socio-economical status):

«The intent was to examine, over an extended period of years, the relationship between social origin and measured intelligence (IQ), the role that IQ and other psycho-social factors play as predictors of social and economic status in adulthood, and the stability of IQ. The question posed by the “Warsaw Studies” was whether, given the virtual absence of educational, health service, and community distinctions (Warsaw in the 1970s was an ideal laboratory for such a sociological undertaking), would Warsaw schoolchildren still show the usual association between parental occupation and offspring intellectual functioning? The results from a series of follow-up studies indicate that the IQ score at age 13 could be viewed as a relatively good indicator for future life outcomes, defined in terms of attained education, occupational status, and material well being. Dramatic differences in this attainment between the groups of respondents with high and low IQ scores attest to this conclusion. Smaller, yet still significant, differences between talented teenagers and their counterparts from the two control groups who apparently did not have the high IQ advantage also support the thesis that IQ matters much for life success.»

Hopefully, they still bothered to correct/adjust for potential confounding factors such as the socio-economic status of their families.

PS:
Granted, the combined effects suggested by both correlations (fertility and socio-economic status, and socio-economic status and IQ scores) might still cancel out the effect caused by the differences between nations in the relative fertility gap difference between socio-economic classes.
On the other hand, the possible correlation between IQ scores and fertility rates might be exclusively dependent on the environmental/non-genetic component that explains part of the differences between IQ scores.

Story
Introduction
If you can say my last name, you've found the right Jane. If you can't, you might have found the right Jane anyway.

I love ecology, networks, geography, and anything that makes me see the world a little differently. I have been described as being "more interesting than an attack goose".

I'm happy when a post inspires active discussion. Please note, however, that non-standard definitions of standard words tend to impede communication. If you insist on such definitions, I will start a new post where you can discuss them to your heart's content and leave the original post to more substantive conversation.
