However, regardless of what your opinions may be, there used to be an entire area of science dedicated to things like this. Phrenology was used to analyze a person’s personality based on the measurements of their skull. Listed below are interpretations of what the shape of your nails may reveal about your personality:
1. The vertically long nail.
You’re probably a real romantic. Even-tempered with a strange but wonderful imagination. You can be a perfectionist and easily overwhelmed. You see the little things that few notice. People really love you. You get along with most people.
2. The broad-sided nail.
Unlike #1, you’re more short tempered. You are, however, a sharp, deep thinker. Even though you’re short tempered, people enjoy you for your straightforwardness. You can tell the difference between the truth and lies. That ability allows you to cut through the BS and offer the best advice. You don’t tell people what they want to hear, you tell them what they need to hear.
3 and 4. The “round-egg” nail.
You’re the endlessly happy one. You’re the pacifist. You’re the laid-back one. You enjoy doing things in a very unique way. You rarely go with the what the majority is doing. Even though you’re in touch with your feelings, you don’t often let them get the better of you.
5. The square nail.
You’re the gutsy one. You’re the one born a natural leader. You have a serious attitude that can put people off, but that makes your playful, good-natured moments all the more pleasant and fun for everyone around you.
6 & 7. The Triangular nail.
You’re the smart ones of the bunch. You’re typically innovative and brilliant when others demand perfection out of you. You often bring new ideas faster than most. People you meet are fascinated by you.
8. The almond nail.
You’re honest, friendly, and faithful. You’re polite but firm when it’s needed. People enjoy spending time with you because you find the good in them. You’re good at handling difficult situations.
9. The sword nail.
Last but not least, the sword nail. In your life, you’re often the tip of the sword. You’re ambitious. You work hard. You have your goals and you won’t stop until you meet them. You’re often well rounded and can handle tasks even far outside of your comfort zone. Your ambition is often contagious.

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.
