Eight-year-old David was begging for money outside a mall when he noticed a homeless man staring at him for a long time. He ran away thinking this person was dangerous, but he caught him and explained something shocking about the boy’s past.
David Donaldson stood outside International Plaza and Bay Street in Tampa, Florida, and couldn’t hold back his tears. His face was covered in wet streaks, and most people only looked at him for a second before they continued walking. He was there to try to raise money for his mother’s funeral.
David’s mother died after a long battle with cancer, and the funeral home was waiting for the money to pay for everything. The manager was worried about the kid, but David had lied to him, explaining that his uncle was coming soon and would be paying for everything.

Sadly, David didn’t have any family left. He was staying at the apartment, but the rent was due soon. He would not be able to pay, and others would soon discover what was going on. They would call CPS, and he would go into the system.
He hated that idea. That’s why he was at the mall, begging people for money. Some shoppers were familiar with the little boy because he also tried to raise funds throughout his mother’s treatment. They would give him a dollar or two before calling the cops. Luckily, David was able to get away from them.
But now, his mother was finally gone, and she deserved to have a nice service. So, once again, he stood outside there with a sign where he wrote what he needed.
After a long sniffle, David dried his tears, thinking that people might be avoiding him because of his crying. He needed that money, so he had to be brave and stop. But once he cleared his eyes using his hands, David saw someone strange. A man was looking at him from the other side of the street. His stare was unnerving.
The man was dressed in tattered clothing, and it was clear he was homeless. David feared he would become like him soon. But an even scarier thought crossed his mind. What if he wants to steal my money? No! My mom needs it!
David gathered his hat from the floor where people had thrown some extra change and started counting. He placed them inside his pocket quickly and raised his head just to see the man cross the street and walk directly toward him.
The boy’s blood went cold, but he had to think fast. That’s when he stood and raced out of there. He could hear the heavy footsteps of the man running after him, and the man yelled, “Wait boy, I want to talk to you!”
“No! This is my mother’s money! Go away!” David screamed back but didn’t slow his pace.

“I don’t want your money, boy! Please, stop!”
The boy didn’t listen, but unfortunately, he entered a dead-end alley and couldn’t escape. “Please, sir. This money is very important. My mother just died, and I need to pay for the funeral,” David pleaded with the man, clutching his right hand over his right pocket where he kept the cash.
The man stopped and approached him slowly now. David could see his unclean state and ragged shirt, but there was something familiar about his face. He also had kind eyes. Maybe he wasn’t lying.
“Again, I don’t want your money, boy. I read your sign. You said your mother died? Can you tell me her name?” the man asked, smiling slightly.
“Maria,” David answered shyly.
“What about you? What’s your name?”
“David Donaldson.”
The man closed his eyes and nodded. Then he looked at the ground, and David could hear his heavy breathing.“Oh, man,” the man whispered and started crying.
“Sir, are you ok? Did you know my mother?” David asked, taking a small step towards the man.
“Yes. I knew her,” the man replied. “But I can’t believe she’s gone. I’m a horrible man.”
“What?”

“Maria… I mean, your mother was my girlfriend around nine years ago. My name is Charlie Donaldson,” the man answered and looked up at him. David could see the tears in his eyes and the sadness in his expression.
“Why do you have my last name?” David questioned, although the eight-year-old was no fool. He already guessed the reason.
“I’m pretty sure I’m your father, kid,” the man revealed.
The boy had no idea what to say, but it was probably true. The man’s face had looked familiar because they shared the same green eyes.
“Ok, so you don’t want to take my money,” David added, just to confirm.
Charlie laughed bitterly. “No, David. I would never do that. I fell on hard times, and that’s why I’m homeless, but I would not take money from a child. Besides, you need to pay for Maria’s funeral, right? That’s what your sign said.”
“Yeah. It’s expensive,” the boy said, scratching the back of his head with one hand.
“Let me ask you something else. Who are you staying with? An aunt or an uncle?”
“No one.”
“Maria told me she had a sister,” Charlie stated with a frown. He wiped the tears that had streaked his face and looked straight at the boy.

“No. I never met anyone, or maybe, they don’t know Mom died,” David continued, not knowing what else to say. It was the truth. It had always been just the two of them.
“And why are you on the streets? Shouldn’t CPS have taken you in?”
“I lied to some people. I told them my uncle was coming soon. I guess they didn’t call anyone,” David answered. But suddenly, he was curious about something. “If you’re my father, why weren’t you in my life?”
“That’s a long story,” Charlie began and said that he had run away as soon as Maria told him she was pregnant. He didn’t want the responsibility. “But in the end, it was the worst thing I ever did. Karma got to me, and I got mixed up with some bad people. I should’ve stayed with your mother and been a father to you.”
They talked more in that dead-end alley and even had a few laughs despite their sad circumstances. Finally, David had an idea. “Why don’t you come live with me so that I won’t be taken away? But on the condition that you will get a job and help me out. I’m a kid. I can’t do anything without an adult without raising suspicion.”

“Are you sure? Do you have a house?”
“An apartment. But rent is due at the end of the month. I don’t have the money. I still have to pay for Mom’s funeral,” David continued.
Charlie thought about it for several minutes. He didn’t have a home and had no idea how to raise a kid. But it was a deal he couldn’t pass up. So he moved in with David, and now that he had an address, he could apply for jobs.
Together, they raised enough for a simple funeral for Maria, and they bonded when Charlie told him stories of their time together. David reciprocated and recounted all the things they did together. Eventually, Charlie found a job at Target and paid rent a few weeks later, as the landlord gave them an extension.
David was able to go back to school instead of begging for alms every day. In the end, they thought of each other as family even if they met under the oddest of circumstances.
What can we learn from this story?
- Don’t run from your responsibilities. Not everyone is ready to have kids, but you can’t run away from your duties.
- It’s never too late to do the right thing. Charlie moved in with David and paid for everything he could, so the kid would not have to be alone.

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.
