The mini-hearts are the first to beat like that of a human embryo. Dubbed cardioid, the miniature heart is the size of a sesame-seed and has a hollow chamber that beats 60-100 times per minute.
Mysterious News Briefly May 24, 2021 Biologists at the Austrian Academy of Sciences in Vienna successfully grew a bundle of human stem cells into a tiny artificial “heart” the size of a sesame seed that could beat rhythmically, squeezing liquid in and out of its chamber-like cavity. A huge success that also ruined eating. Read more »

Scientists have successfully grown a bundle of human stem cells into a tiny artificial heart the size of a sesame seed.
The pulsating mass is the first self-organizing miniature organ to resemble the human heart, including a hollow chamber enclosed by a wall of cardiac-like tissue.
Simple heart-like organs, or cardioids, have been built in the lab before, but only using a scaffold, a mold, or a matrix for the cells to assemble around.
This new cardioid model spontaneously constructed itself. All scientists had to do was coax the pluripotent stem cells in their dish using six signaling pathways known to coordinate heart development in the human embryo.

Thermo Fisher Scientific, the world leader in serving science, has developed a custom-built high-resolution scanning transmission electron microscope ((S)TEM) to support advanced materials research at Monash University. The instrument is being installed in the Monash Centre for Electron Microscopy (MCEM) in Melbourne, Australia, a node of Microscopy Australia.
The Thermo Scientific Spectra φ is configured to provide enhanced electron beam flexibility to optimize advanced imaging of complex material systems. The Spectra φ was designed and built to meet the specifications of a team led by Professor Joanne Etheridge, of MCEM and Fellow of the Australian Academy of Science. By incorporating Spectra φ into their instrument lineup, Monash University will continue driving groundbreaking
