The main reason of humanoid robots isn't that the people think that it is a person, it's because our environment is made for humans and because of this the design to best fit in this environment with several different tasks. The little bot in the article never be apable to wash your dishes, climb stairs or serve you an beer from the fridge. Robots made for one specific task, certainly can have a design specific for it, there isn't needed an humanoid design.

Anyway this turns only absurd if it referred to the exact pole, geographic or magnetic, but not from the continent as is.

Just in the South of the Arctic

China isn't communist, but way kess stupid as the US, that is the main difference. It's something like a state capitalism, not depending on private lobbies as in the other capitalist systems. A real comunist state don't currently exist in the world (no, also not North Corea, it's a fascistic dictatorship, not so far from what will be the US with Trump in the near future)

For Trump, he needs two hands to drink a glass of water

Also very interesting for musicians

Good idea, but here it is not the best place to expose it, it is not an official channel, mainly dedicated to news in Vivaldi. To suggest functions, ideas or questions is better to expose them in the forum, there you can have direct contact with the team.

Agree, I like also a strong Expresso with Latte Art, while listening Insomnium or an Irish Coffee and Eluveitie

I don't know, try it

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]
