How global warming and mind-eating parasites are creating a global intelligence gap
For an affluent Western country, the United States has an usually high proportion of its people living in warm-to-tropical climates, which are breeding grounds for parasites.
Schistosomiasis and toxoplasmosis may sound like something you would pick up in a developing country, but the reality is that more and more so-called "third world" parasites are becoming endemic to the United States. Already, some 60 million people — that’s right 60 million — are infected with toxoplasma gondii or, as it's more fondly known as, the “cat poop parasite.”
But don’t freak out about your pet just yet — it could be worse, and by worse I mean having a tapeworm eat your brain. There have been at least 2,000 cases of neurocysticercosis in the U.S. and 5 million or more cases worldwide, which cause epileptic-like symptoms when this normally gut-eating parasite takes up residence in the cerebrum. There’s also Chagas disease, most commonly found in Latin America, which affects the cardiovascular system and can lead to heart failure. In 2007, U.S. blood banks began screening for the disease and found alarmingly high rates among poor communities in Florida and Texas.
Not only are parasites a public health concern, but also they take an untold toll on human intelligence.
So why are parasites flourishing in the U.S.? For an affluent Western country, the United States has an unusually high proportion of its people living in warm-to-tropical climates, which are breeding grounds for parasites. Moreover, as global warming continues, these parasites find more areas that are amenable to their proliferation. In addition, there is relatively low public awareness about the likelihood of contracting such parasites — malaria happens only in Africa, right?
If parasites aren’t reined in effectively, they not only threaten public health, but also could reduce human capital.
Not only are parasites a public health concern, but also they take an untold toll on human intelligence. Researchers at Johns Hopkins found ACTV-1, a chlorovirus, in two out of every five subjects. Normally found in algae, the pathogen somehow made a rapid evolutionary leap from infecting plant matter to humans and the cost was diminished cognition in those participants who were infected. According to The American Scholar, “When compared with those who did not harbor the virus, those infected were about 10 percent slower to make calculations and had a reduced attention span, suggesting that the virus compromised their ability to calculate, to focus, and to process visual information — disadvantages in the classroom, on the job, and in other familiar learning situations.”
These findings are disturbing on many levels and further reinforce the need for greater access to health care, especially for the nation’s poorest. If parasites aren’t reined in effectively, they not only threaten public health, but also could reduce human capital.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
A recent study gives new meaning to the saying "fake it 'til you make it."
- The study involves four experiments that measured individuals' socioeconomic status, overconfidence and actual performance.
- Results consistently showed that high-class people tend to overestimate their abilities.
- However, this overconfidence was misinterpreted as genuine competence in one study, suggesting overestimating your abilities can have social advantages.
Is this proof of a dramatic shift?

Dramatic and misleading

The situation today: CNN pushed back to the edges of the country.
Over the course of no more than a decade, America has radically switched favorites when it comes to cable news networks. As this sequence of maps showing TMAs (Television Market Areas) suggests, CNN is out, Fox News is in.
The maps are certainly dramatic, but also a bit misleading. They nevertheless provide some insight into the state of journalism and the public's attitudes toward the press in the US.
Let's zoom in:
- It's 2008, on the eve of the Obama Era. CNN (blue) dominates the cable news landscape across America. Fox News (red) is an upstart (°1996) with a few regional bastions in the South.
- By 2010, Fox News has broken out of its southern heartland, colonizing markets in the Midwest and the Northwest — and even northern Maine and southern Alaska.
- Two years later, Fox News has lost those two outliers, but has filled up in the middle: it now boasts two large, contiguous blocks in the southeast and northwest, almost touching.
- In 2014, Fox News seems past its prime. The northwestern block has shrunk, the southeastern one has fragmented.
- Energised by Trump's 2016 presidential campaign, Fox News is back with a vengeance. Not only have Maine and Alaska gone from entirely blue to entirely red, so has most of the rest of the U.S. Fox News has plugged the Nebraska Gap: it's no longer possible to walk from coast to coast across CNN territory.
- By 2018, the fortunes from a decade earlier have almost reversed. Fox News rules the roost. CNN clings on to the Pacific Coast, New Mexico, Minnesota and parts of the Northeast — plus a smattering of metropolitan areas in the South and Midwest.

This sequence of maps, showing America turning from blue to red, elicited strong reactions on the Reddit forum where it was published last week. For some, the takeover by Fox News illustrates the demise of all that's good and fair about news journalism. Among the comments?
- "The end is near."
- "The idiocracy grows."
- "(It's) like a spreading disease."
- "One of the more frightening maps I've seen."
- "LOL that's what happens when you're fake news!"
- "CNN went down the toilet on quality."
- "A Minecraft YouTuber could beat CNN's numbers."
- "CNN has become more like a high-school production of a news show."
Not a few find fault with both channels, even if not always to the same degree:
- "That anybody considers either of those networks good news sources is troubling."
- "Both leave you understanding less rather than more."
- "This is what happens when you spout bullsh-- for two years straight. People find an alternative — even if it's just different bullsh--."
- "CNN is sh-- but it's nowhere close to the outright bullsh-- and baseless propaganda Fox News spews."
"Old people learning to Google"

CNN vs. Fox News search terms (200!-2018)
But what do the maps actually show? Created by SICResearch, they do show a huge evolution, but not of both cable news networks' audience size (i.e. Nielsen ratings). The dramatic shift is one in Google search trends. In other words, it shows how often people type in "CNN" or "Fox News" when surfing the web. And that does not necessarily reflect the relative popularity of both networks. As some commenters suggest:
- "I can't remember the last time that I've searched for a news channel on Google. Is it really that difficult for people to type 'cnn.com'?"
- "More than anything else, these maps show smart phone proliferation (among older people) more than anything else."
- "This is a map of how old people and rural areas have learned to use Google in the last decade."
- "This is basically a map of people who don't understand how the internet works, and it's no surprise that it leans conservative."
A visual image as strong as this map sequence looks designed to elicit a vehement response — and its lack of context offers viewers little new information to challenge their preconceptions. Like the news itself, cartography pretends to be objective, but always has an agenda of its own, even if just by the selection of its topics.
The trick is not to despair of maps (or news) but to get a good sense of the parameters that are in play. And, as is often the case (with both maps and news), what's left out is at least as significant as what's actually shown.
One important point: while Fox News is the sole major purveyor of news and opinion with a conservative/right-wing slant, CNN has more competition in the center/left part of the spectrum, notably from MSNBC.
Another: the average age of cable news viewers — whether they watch CNN or Fox News — is in the mid-60s. As a result of a shift in generational habits, TV viewing is down across the board. Younger people are more comfortable with a "cafeteria" approach to their news menu, selecting alternative and online sources for their information.
It should also be noted, however, that Fox News, according to Harvard's Nieman Lab, dominates Facebook when it comes to engagement among news outlets.
CNN, Fox and MSNBC

For the record, here are the Nielsen ratings for average daily viewer total for the three main cable news networks, for 2018 (compared to 2017):
- Fox News: 1,425,000 (-5%)
- MSNBC: 994,000 (+12%)
- CNN: 706,000 (-9%)
And according to this recent overview, the top 50 of the most popular websites in the U.S. includes cnn.com in 28th place, and foxnews.com in... 27th place.The top 5, in descending order, consists of google.com, youtube.com, facebook.com, amazon.com and yahoo.com — the latter being the highest-placed website in the News and Media category.
If you thought your mother was pushy in her pursuit of grandchildren, wait until you learn about bonobo mothers.
- Mother bonobos have been observed to help their sons find and copulate with mates.
- The mothers accomplish this by leading sons to mates, interfering with other males trying to copulate with females, and helping sons rise in the social hierarchy of the group.
- Why do mother bonobos do this? The "grandmother hypothesis" might hold part of the answer.
