‘Tour de force of microbiology’ as scientists recreate eukaryotic cell that sparked life on Earth | News

A case could be made that the most significant moment on Earth occurred two billion years ago when a single-cell organism engulfed another to form the building block of complex life. Everything, from fungi to humans, emerged from the eukaryotic cell. Researchers have now created an organism similar to that fateful one in a “tour de force of microbiology” that has illuminated one of the most mysterious and important chapters in life. The reason multi-celled organisms such as animals and plants exist at all is because of an ancient symbiosis. Scientists believe that a single-cell organism called an archaea trapped a bacterium one day.

In addition to creating and viewing videos featuring the brand’s sponsored hashtag, a separate tab features an in-app experience where products from the campaign can be purchased within TikTok itself. Last week, Kroger was the first brand to try out the new feature, according to a report from AdWeek. While not exactly a company that exudes youth appeal, Kroger found a way to reach TikTok’s young adult audience through their hashtag campaign.
