(NewsNation) — Bad news for the tooth fairy: Humans may be one step closer to regrowing their teeth with the help of a new drug from Japanese researchers.

The intravenous treatment suppresses uterine sensitization-associated gene-1 (USAG-1) protein, the antibody which prevents tooth regrowth.

Scientists at Kyoto University Hospital will conduct the first human trial of the drug from September 2024 to August 2025. In tests on ferrets and mice, the drug worked with no notable side effects, Popular Mechanics reported.

The drug will be used on 30 men between 30-64 who are missing at least one molar. From there, researchers will expand the study to those with partial edentulism, or those missing one to five permanent teeth.

“We want to do something to help those who are suffering from tooth loss or absence,” said lead researcher Katsu Takahashi, head of dentistry and oral surgery at Kitano Hospital told NewAtlas. While there has been no treatment to date providing a permanent cure, we feel that people’s expectations for tooth growth are high.”

If the trial is effective, the medicine could be commercially available as soon as 2030.

(NewsNation) — Sen. James Lankford, R-Okla., lamented on Sunday the Senate’s failure to pass bipartisan legislation on the southern border and blamed the lobbyist culture of Washington, D.C.

“There are so many outside groups that are built around not getting things done,” he said on NewsNation’s “The Hill Sunday.” “It’s the old consulting joke: If you can’t solve a problem, there’s good money to be made prolonging it. And that’s where we are in the cycle at this point.”

Republicans in February resisted advancing a bipartisan proposal intended to clamp down on illegal border crossings. In a speech on the Senate floor just before the vote, Lankford, who crafted the proposal, said it was a chance for the Senate to decide “if we’re going to do nothing, or something.”

“It’s an issue that’s bedeviled, quite frankly, this body for decades,” Lankford said. “It’s been three decades since we’ve passed anything into law to be able to change border security.”

In the meantime, Lankford says illegal border crossings have only become more frequent since the bill was scuttled, largely by his own party.

“We have 10 million people that have illegally crossed in the last three and a half years,” he said. “That’s more than the previous 12 years combined.”

Lankford said coming to a bipartisan consensus on the situation at the U.S.-Mexico border shouldn’t be difficult.

“It’s a controversial issue because there are so many people in Washington, D.C., and around the country, who get email blasts with information that literally pushes out to them ‘Don’t allow your people to be able to vote for this because it has this in it.’ And it creates so much noise.”
