m/s is the best, everyone know aprox. what is an meter and an second to know the velocity, but not so easy with km and a hour.. 50km/h seems slow, but not so 13 m/s.

Certainly also nazis upload their trash there, same as in all other platforms, seen include in Mastodon instances, also in YT. That cant be avoided in public accesible platformas.

Or south from the Equator line.

It is vallid to substitute ä with ae, ö with oe and ü with ue, if you don't have an German or also Spanish keyboard (¨ is also used in Spain, but in a different way, to put weight on a letter)

Doomsday nowadays is an nuclear explosion 200km above a country, back to the 18 Century in milliseconds. Lights off, all electronic devices converted to paperweights, no water, no fuel, no transports, no communication....Mad Max.

Before using in humans, they need to test it first in animals. Neurochips and VR glasses are already on the way, until now FOX News and X are only partial satisfactory.

The best alternatives for creators to obtain revenue are Bandcamp and Odysee, they have an fair business modell. Certainly when YT said selfhosting is harmfull, it's only for their business modell, but if creators create their own pages with their work, it's not really a solution, it will be interesting only for direct fans.

Like the horse, I also use the middle fingers while walking.

It's possible, I think that DNS4EU seems a improved version.

Andi's Writeup

Recent research shows significant advances in using hydrogels to restore lost teeth and dental tissue through several approaches:

Injectable Hydrogels for Tooth Pulp Regeneration

  • Researchers at NJIT developed a first-of-its-kind injectable hydrogel that triggers the body to regenerate lost tooth pulp, funded by a $3 million NIH grant[^3]
  • The material recruits dental pulp stem cells to rebuild tissue without requiring live cells, making it viable for off-the-shelf use[^3]
  • Early animal trials showed formation of soft tissue, blood vessels, and nerve bundles within a month[^3]

Enamel Regeneration

  • Scientists in China created a gel containing mineral clusters that can stimulate crystal regrowth to restore eroded tooth enamel[^18]
  • Tel Aviv University researchers developed a water-based hydrogel that encourages bone regrowth, potentially transforming dental implant procedures[^5]
  • USC researchers engineered peptide-based hydrogels that can rebuild tooth enamel structure and restore early cavity damage[^23]

Periodontal Tissue Engineering

  • Hydrogels are being used as scaffolds to regenerate periodontal ligament, alveolar bone, and cementum[^2]
  • Key components include:
    • Natural polymers like chitosan, sodium alginate, and hyaluronic acid
    • Synthetic polymers such as polyethylene glycol and gelatin methacryloyl
    • Bioactive substances including antibiotics, growth factors, and stem cells[^2]

Future Development

  • Japanese researchers aim to begin human trials for tooth regeneration within 6 years[^20]
  • Current challenges include:
    • Creating sufficient blood vasculature
    • Controlling bacterial growth
    • Improving mechanical properties
    • Achieving complete periodontal regeneration[^2]
