As the saying goes, "the sky is the limit". This is true for scientists conducting the first oral health experiment in space to evaluate the growth and response of oral bacteria to the agents being treated in zero gravity.

In order to better understand the growth and metabolism of oral biofilms, scientists are conducting a new oral care experiment in space.

As the saying goes, the sky is the limit. This is true for the scientists conducting the first oral health experiment in space to investigate the growth and response of oral bacteria to treatment agents in zero gravity. The project, which is being sponsored by the International Space Station U.S. National Laboratory and conducted in collaboration with NASA and Colgate-Palmolive, will last two months and is partly aimed at improving oral health treatment on the ground.

SpaceX launched thousands of tiny sea creatures to the International Space Station on Thursday, along with a plaque-fighting toothpaste experiment and powerful solar panels.

The 3,300-kilogram shipment — which also includes fresh lemons, onions, avocados and cherry tomatoes for the station's seven astronauts — should arrive on Saturday.

Rocket due to reach the International Space Station this weekend is loaded with 7,300lb of fresh food and supplies for an orbiting lab.

The University of Nevada, Las Vegas is teaming up once again with NASA to conduct research, this time to determine if oral bacteria grows the same way in weightlessness as it does in the mouths of humans on Earth.
