People are frequently seen debating something or other on the internet these days.
Given that it essentially brought millions of people together in one location and allowed them to freely express their emotions, it was unavoidable. But they were always going to spark a heated argument, regardless of how diametrically opposed they were.
Even while contentious images and videos are becoming commonplace on the internet, it doesn’t mean it’s not worthwhile to check them out whenever they appear. Thus, when I saw a photo of a father and his dozing kid shot during a flight—one that, incidentally, has sparked a variety of comments—we had to share it.
The discussion started when Reddit user u/therra123 posted a wonderful photo of a father and daughter in the r/MadeMeSmile thread.
An image of a girl curled up on her aisle seat during a trip was submitted by the user. Her father had put his palm under her cheek, preventing her head from resting on the armrest, which is, I’m sure anyone who has used one, a quite harsh and coarse pillow.
“This man kept his hand in this position for 45 minutes so his daughter could sleep well,” says the Reddit caption that goes with the image.
We have to say at this point that, in our perspective, this appears to be no more than a father going about his business. Although the post was appropriately labeled “wholesome moments,” some Redditors disagreed.
Remarkably, the father’s activities drew criticism; some individuals wrote merely to point out that he could have done it more skillfully.
The widely shared post received approximately 60,000 likes and thousands of comments, with responses like these:
“It seems like… I believe there must be a better approach.
“Do you not have your towel?” said another. The most crucial item you can pack is a towel.
“Shows a distinct lack of creative problem solving,” said a third person. You claim that after 45 minutes, you were unable to come up with a workable answer. Hey!
A fourth person wrote, “Seriously. Fold up a sweatshirt, and presto! Instant-pillow. Here’s an absurd idea: request a blanket and pillow from a flight attendant.
Others, meanwhile, were more understanding of the father and his gesture. By coincidence, we also find ourselves in that category!
What about you, though? Was there anything improper, in your opinion, with the father using his kid as a makeshift pillow throughout this flight? Tell us in the comments below.
We’ve All Waited for It: Scientists Created a Drug That Can Help Regrow Lost Teeth
The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the child’s pillow, but they be assured of a replacement tooth in a few months. Unfortunately, the scenario is quite different for adults grappling with a loss of teeth. Luckily, there may be some hope thanks to a new study performed by scientists at Kyoto University and the University of Fukui.
A dental breakthrough
While the typical adult mouth houses 32 teeth, approximately 1% of the population exhibits variations of them, either possessing more or fewer teeth due to congenital conditions. Researchers have delved into the genetic factors behind cases of excessive teeth, seeking valuable insights into the potential regeneration of teeth in adults. This study is the first to show that monoclonal antibodies can help regrow teeth. It suggests a new way to treat a dental problem that currently requires implants and other artificial solutions.
A bit of science
The research team disclosed that an antibody targeting a specific gene, known as uterine sensitization-associated gene-1 (USAG-1), can induce tooth development in mice affected by tooth agenesis, a congenital condition. The findings were published in the journal, Science Advances.
As per Katsu Takahashi, a senior lecturer at the Kyoto University Graduate School of Medicine and one of the principal contributors to the study, the essential molecules crucial for the development of teeth have already been pinpointed. “The morphogenesis of individual teeth depends on the interactions of several molecules including BMP, or bone morphogenetic protein, and Wnt signaling,” says Takahashi.
On April 13, 2021, the University of Kyoto posted its first pic of newly-grown teeth in mice.
BMP and Wnt are involved in more than just tooth development; they affect the growth of organs and tissues early in the body’s development. Because drugs affecting them directly might have broad side effects, scientists are cautious. To find a potentially safer method, researchers focused on the gene USAG-1, thinking that aiming at factors countering BMP and Wnt specifically in tooth development could be more precise.
“We knew that suppressing USAG-1 benefits tooth growth. What we did not know was whether it would be enough,” added Takahashi.
The first results
Scientists looked at how different monoclonal antibodies affect USAG-1. Monoclonal antibodies are often used to treat things like cancer and arthritis and for making vaccines. Tests with this antibody showed that BMP signaling is crucial for deciding the number of teeth in mice. Also, just one treatment was enough to grow a whole tooth. Further tests confirmed these positive results in ferrets too.
“Ferrets are diphyodont animals with similar dental patterns to humans. Our next plan is to test the antibodies on other animals, such as pigs and dogs,” explained Takahashi.

The next steps
Now, scientists are going to test the drug on healthy adults. If that goes well, the team plans to try it on kids aged 2 to 6 with a rare tooth problem called anodontia, a genetic disorder defined as the absence of all teeth. These kids will get one shot of the drug to see if it makes their teeth grow. If everything works out, the medicine might be approved by 2030.
Takahashi sees the new medicine as an additional choice for individuals who are missing some or all of their teeth.
“The idea of growing new teeth is every dentist’s dream,” Takahashi told the Japanese newspaper, The Mainichi in June this year. “I’ve been working on this since I was a graduate student. I was confident I’d be able to make it happen.”
So hopefully, by the year 2030, humans will get a chance to have their third generation of teeth grown and say goodbye to implants. Until then, make sure to keep your teeth strong and healthy — this article will help you with that.
