Undoubtedly, the importance of a good night’s sleep for overall health is widely acknowledged. With numerous studies exploring the optimal ways to achieve quality rest, recent research proposes a surprising solution, sharing the bed with dogs. Canisius College in New York State spearheaded this unconventional investigation, revealing that women experience better sleep next to their canine companions compared to human or feline counterparts.
Lead researcher Christy Hoffman, Ph.D., an animal behaviorist, conducted a survey involving nearly a thousand women across the United States to draw these intriguing conclusions. The results unveiled that 55% of participants shared their beds with at least one dog, 31% with a cat, and 57% with a human partner.
Hoffman delved into the reasons behind dogs emerging as superior sleep partners. The study highlighted that dogs’ sleep patterns align more closely with humans than those of cats. Hoffman theorizes that this synchronization may contribute to improved sleep quality, as dogs are adept at accommodating their owners’ sleep schedules, potentially mitigating disruptions caused by differing bedtime routines.
Furthermore, the structured routines imposed by dogs, such as morning walks, assist in regulating their owners’ daily schedules, thereby enhancing overall sleep quality. Another contributing factor is the physical stillness of dogs during sleep, unlike fidgety feline companions. Women in the study reported that dogs tended to remain on the bed throughout the night, fostering a sense of security and stability.
The study’s third crucial finding emphasizes the unique sense of security that dogs provide. Unlike cats or even human partners, dogs offer a heightened level of psychological comfort. Hoffman suggests that the perception of dogs as vigilant protectors, capable of alerting their owners to potential intruders, plays a role in enhancing the sense of security.
Despite these intriguing findings, the study acknowledges the subjectivity of sleep preferences. Factors such as a dog’s snoring or generating excess warmth could pose challenges. Additionally, there are individuals who find solace in the companionship of cats during bedtime.
It’s essential to note that the study relies on participants’ subjective perceptions of their pets’ impact on sleep quality and duration. Consequently, further research is necessary to definitively crown dogs as superior sleeping partners. Hoffman emphasizes the need for continued exploration into the various contexts under which pets positively or negatively influence sleep quality.
As American households increasingly welcome pets, understanding these dynamics becomes crucial. Future research may utilize technologies like Fitbit-like devices to objectively track sleep quality in diverse sleeping conditions, providing a more comprehensive understanding of the intricate relationship between humans and their animal companions during bedtime.
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.
