Pregnancy with a side of pregnancy
It was a great day when Rebecca Roberts and her partner went to the obstetrician to confirm their positive pregnancy test. They’d been trying for more than a year without success, and now they would be having a baby. Note the usage of the singular there. That will become important in a moment.
When Ms. Roberts went back for her 12-week ultrasound appointment, there was an unexpected complication: Baby had become babies. The original fetus was there and doing fine, but there was now a second, less-developed fetus who’d invited herself in unannounced. While they were technically twins, the second fetus did not form at the same time, like normal fraternal twins, instead forming from an egg that was released weeks after the first egg was fertilized.
The phenomenon, called superfetation, is incredibly rare. Prior to 2008, there were fewer than 10 reported cases in the world, according to the European Journal of Obstetrics & Gynecology and Reproductive Biology. The odds of an egg being released during pregnancy, something that’s not supposed to happen, and then having that egg also become fertilized and successfully implanted in the uterus, is astronomically small.
It was not an easy pregnancy for Ms. Roberts, and at 33 weeks into the first pregnancy, the younger fetus’s umbilical cord began to malfunction, so delivery for both was induced in September 2020. Both infants spent time in the neonatal ICU, with the younger baby being in for 3 months, but after 6 months both are doing well and developing quickly. It’s always nice to have a happy ending to one of these weird medical phenomena, especially one with such an unpleasant-sounding name. If we didn’t know better, we’d think superfetation was something really, really smelly.
What’s a little misinformation among neighbors?

Vaccination will, hopefully, get the COVID-19 pandemic under control at some point, but the related misinformation floating around the Internet is another story. Already rampant in the United States, it’s now spreading … to Canada.
Investigators from that northern land took a look at the Twitter accounts of the platform’s 187,000 most active Canadian users and eventually ended up with a database of 147 million tweets, of which 154,000 contained terms associated with misinformation.
The Canadian social media users had more exposure to information from the United States than from Canada, and the exposure to U.S. outlets was more likely to involve misperceptions about COVID-19. “Most of the misinformation circulating on Twitter shared by Canadians was retweeted from U.S. sources,” the researchers said, and “Canadians who followed more American users were more likely to post misinformation.”
The study’s lead investigator, Aengus Bridgman of McGill University in Montreal, put it this way: “It’s hard for Canadian journalists, scientists, and public health experts to be heard by the average Canadian, given all the noise generated by American sources.”
People generally don’t take the time to read the fine print on contracts, and it looks like the Canadians have fallen into that trap. Not entirely their fault, of course, because most people coming from Canada to America don’t pass the Statue of Liberty, but she’s got some fine print of her own.
That poem written on the pedestal, the one that says, “Give me your tired, your poor, your huddled masses yearning to breathe free”? It’s actually a contract, and at the bottom, in very small print, it says, “In return for acceptance of the aforementioned ‘huddled masses,’ countries of origin agree to accept all of the social media noise generated by American sources.”
Sorry, Canada, but we gotcha.
