If you’ve ever explored your grandparents’ house, you’ve probably found some strange items that left you puzzled.
Recently, someone online shared a photo of some metal tools that, if it weren’t for the nut-shaped bowl they’re in, could be mistaken for tiny weapons.
People online quickly started guessing what these odd tools were for, with one person even joking that they might be used to “find cavities.” Curious to know more about this mysterious tool? Keep reading!
Most of us have heard of a nutcracker—not the ballet with the Sugar Plum Fairy, but the metal tool used to crack open nuts.
A nutcracker looks like pliers and usually has two metal arms with a hinge at the top. The arms are often serrated to grip the nut better. You place the nut in the jaws of the nutcracker, squeeze the arms together, and the shell cracks open, revealing the nut inside.
Nutcrackers come in all sorts of designs and sizes, from simple handheld ones to fancy, decorative pieces.
Some are made for specific types of nuts, while others can handle a variety of nuts and even shellfish like lobster or crab.
Getting the nut out of its hard shell isn’t always easy. After cracking the shell, you still have to deal with the meat sticking to the tough walls inside.
That’s where a nut pick comes in, which is the tool that’s confusing people online.
Nut picks come in different styles and materials, like metal, wood, or plastic. Some even have fancy handles or are designed to be comfortable to use.
They’re useful for enjoying all kinds of nuts, such as walnuts, pecans, and almonds, where you need to get the edible part out of the shell.
People online have been sharing their experiences with these versatile tools.
One person remembered the hard work of cracking nuts in the past, saying, “We used them for walnuts. Back then, you didn’t buy pre-cracked walnuts for baking; you had to crack them open yourself.”
Another user shared, “We used them for walnuts, pecans, and more. They came with the nutcracker and were also great for getting lobster out of those tiny legs.”
Someone else mentioned, “They’re crab and lobster meat picks. I’m lucky to still have my family’s set. Growing up near Maine, we had lots of chances to use them!”
Another person added that she’s found multiple uses for the pick, saying, “I’ve used them for their intended purpose, but as an artist, I’ve also found other ways to use them.”
Others had different ideas. One user said, “They’re called olive picks, but you can use them for other things, so your hands don’t touch the food.” Another joked, “Mostly used to pick your teeth after a big dinner… also handy for finding cavities!”

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.
