INSIDE THE ORION NEBULA
This is a wonderful shot showing us one of the most beautiful regions of the sky.
IC 434 is an emission nebula visible in the constellation Orion. In the center of the photo we can see the famous Horsehead Nebula, a dark cloud overlapping it in our line of sight.

Humans may regrow lost teeth soon.
🦷 Humans may soon regrow lost teeth!
A team of doctors in Japan has developed a groundbreaking drug that could allow people to naturally grow a brand-new tooth.
Instead of relying on dentures or implants, this treatment activates the body’s own ability to produce another set of teeth. The research is led by Dr. Katsu Takahashi at Kitano Hospital’s Medical Research Institute. His team discovered that by blocking a protein called USAG-1—which normally prevents extra teeth from forming—they could trigger tooth growth. In experiments with mice, the treatment worked successfully. Now, human clinical trials are being prepared, with hopes of making the therapy available by 2030.
Scientists believe humans may still have hidden “third set” tooth buds, just waiting to be switched on. This idea is inspired by animals like sharks and elephants, which naturally replace their teeth throughout life. Combined with advances in dental tissue and bone regeneration, researchers are confident that reversing tooth loss biologically is within reach.
If all goes well, the next decade could make tooth regrowth a real option for millions of people who lose teeth due to age, injury, or disease.
