Lab-grown heart beats perfectly

Plus: A mysteriously long 'radio heartbeat' is coming from a distant galaxy. Jul 15, 2022 [Blueprint]( Researchers at the University of Toronto have [grown a miniature model]( of the left ventricle of the human heart using living heart cells. It beats like a regular heart and even pumps fluid under laboratory conditions. According to the World Health Organization, heart-related conditions are the leading cause of death globally, so this is a major development. However, at the moment the tissue can only create about 5 percent of the ejection pressure of a human heart, so there’s a way to go. But the researchers say they are confident the tissue can be scaled up in the future. But be still the beating heart for just a second… before you jump into that, [check out]( the $20 device that managed to break into an $80,000 Tesla. Yes, really. Good morning.

[Must Read]MUST READ [Lab-grown artificial heart part has living cells, and it beats perfectly]( [Lab-grown heart]( A miniature model of the left ventricle of the human heart has been [grown using living heart cells](. Researchers at the University of Toronto have said it can beat like a regular heart and even pump fluid under laboratory conditions. The researchers used tiny scaffolds made from biocompatible polymers to make their tissue in three dimensions, as opposed to the two-dimensional cultures that are normally used in laboratories. They said they chose to recreate the left ventricle because it’s the heart's main chamber and pumps oxygenated blood into the aorta, which then carries it to the rest of the body. → This is relevant because according to the [World Health Organization]( heart-related conditions are the leading cause of death globally.
