“Can’t believe my view on the plane. It was like this the whole four-hour flight,” X user captioned the pics. A plane passenger named Flea was surprised to witness two of his fellow travelers getting extremely cozy on a recent flight. He took to social media to share his frustration, posting pictures of the couple’s intimate display across a row of seats. The duo, barefoot and entwined in a spooning position, had their feet sticking out into the aisle, much to Flea’s horror.
This incident stirred the airplane etiquette debate, following others like feet on seats and seatbelts around ankles.
Flea shared three photos online showing a couple lying across three seats on a plane. The woman had her legs wrapped around her partner, with her bare foot on the tray table. In another photo, they were making a heart shape with their hands. The third picture showed the man with one bare foot on the floor while the woman rested on top of him.
Many people commented online, expressing their disapproval of the couple’s behavior, especially being barefoot and taking up multiple seats. Some questioned why the flight attendant didn’t intervene, while others were specifically bothered by the bare feet.
People started a heated debate.
One user wrote, “I would have stared at his feet the whole time.” Another user on X commented, “This isn’t even safe.”
Another commenter remarked, “Breaking up in two months.” Someone else shared, “I hated these types of couples in high school, all in the hall, slowing you down.”
This incident isn’t the first time airplane passengers have sparked debates over etiquette. Just a few weeks ago, there was an uproar when a frequent flier demonstrated a risky travel hack of wearing her seatbelt around her ankles to sit more “comfortably” during the flight.
Air travel brings people together despite occasional etiquette lapses, emphasizing diversity and mutual respect.
Despite the debates and occasional lapses in etiquette, air travel continues to connect people from all walks of life. These incidents, while they may cause frustration or amusement, also highlight the diverse experiences and perspectives we encounter during our journeys.
Ultimately, the shared experience of flying brings us together, reminding us of the importance of mutual respect and understanding in our interconnected world. What’s your take on this situation?
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.
