Richmond had jumped from 42 points behind to secure a superb win over the Brisbane Lions at MCG. In Sunday’s other fixtures, the Gold Coast beat the West Coast by three points, while Essendon beat COVID-hit North Melbourne by eight goals. After conceding the first six goals for most of the game against the Lions, the Tigers took the lead in the 16th minute of the final quarter. The two sides traded punches for the final stages, with veteran Mitch Robinson missing a golden opportunity to put the Lions back in front after picking up a free kick from 15 yards. A fatal error from defender Darcy Gardiner allowed Tigers star Tom Lynch to score his fourth and last-minute winner. The Tigers ended a three-game winless run to win 15.14 (104) to 14.13 (97) in Shane Edwards’ 300th senior appearance. Importantly for Richmond, it provides a great opportunity for the ninth-placed Tigers to play in this year’s final with the last three games in favor of the season. But for the Lions, this is a major b

Heart disease – the leading cause of death in the US – is so deadly in part because the heart, unlike other organs, cannot repair itself after injury. That is why tissue engineering, which ultimately includes the wholesale manufacture of whole human hearts for transplantation, is so important to the future of cardiac medicine. To build the human heart from the ground up, researchers needed to replicate the unique structures that make up the heart. This includes recreating the helical geometry, which creates a circular motion when the heart beats. It has long been theorized that this circular motion is essential for pumping blood at high volumes, but proving it is difficult, in part because creating hearts with different geometries and alignments is a challenge. Now, bioengineers from Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed the first biohybrid model of the human ventricle with helically aligned beating heart cells, and have shown that
