Beyond the School
Despite being essential members of our community, teachers frequently receive little recognition. Their lives are devoted to instructing, modeling, and guiding the next generation. One such hero is Jonathan Oliver, a physical education teacher at Valdosta, Georgia’s WG Nunn Elementary School, who recently won over many people’s hearts with his kind deed.
A Small Motion That Has a Huge Effect
Kristen Paulk, one of Oliver’s kindergarten students, came up to him during a basketball game asking for assistance. She requested that he restyle her hair into a ponytail. Oliver picked up a basketball, bent over, and immediately set about pulling Kristen’s braids out of her face. He had no idea that Kandice Anderson, a colleague educator, had recorded the touching incident on camera.
Touching Hearts All Around
The moment Anderson uploaded the video to YouTube, it became extremely popular. The video’s title, “When your job goes beyond teaching!” sums it all up.The public expressed their sincere gratitude and support for Oliver. Good Morning America noticed the clip and contacted Oliver to set up an interview.
A Modest Instructor
Oliver said in the interview, “We all do it, so I never expected it to receive so much attention.” “We want the students to have a great time and feel comfortable here. Oliver saw helping Kristen with her ponytail as just another day of providing his kids with the kind of attention they need. We strive to show them love as often as we can.
Beyond Style of Hair
Oliver assisted Kristen with her ponytail even though he isn’t a hair stylist. He made the amusing comment that anything more complicated than a ponytail would mean calling her mother for help. Miyah Cleckley, Kristen’s mother, conveyed her appreciation for Oliver’s gentle disposition. She said, “I always know Kristen is in very good hands with him.” Cleckley, who has one son and five daughters, is grateful for Oliver’s assistance.
We are reminded of the compassion and commitment found in our educational system by educators such as Jonathan Oliver. Even if their good deeds can go unappreciated, their influence is immense.
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.
