In the future, you might not have to resort to exotic materials to create heart cells — you could just raid your grocery store’s produce section. Scientists have invented a process that turns spinach leaves into farms for functioning human heart cells. The team started by pumping a detergent solution through the spinach, stripping it of its plant cells and turning it into a ghostly shell made mostly of cellulose. After that, they cultured heart cells on the remaining structure, sending both fluids and microscopic beads through the vegetable’s now-empty veins in order to feed the new cells.

IF YOUR MOTHER ever warned you not to eat apple cores, it was with good reason. Yeah OK, so apples don’t really havecores, but they do have those rough middle sections full of seeds, and those seeds can harbor concentrations of molecules called cyanogenic glycosides. One of those is amygdalin, and when it gets down into your gut bacteria, it can turn into cyanide, which can do a pretty good job of killing you.
Tomorrow, two American astronauts will boldly go where several people have gone before. In the early hours of September 1 astronauts Jeff Williams and Kate Rubins will embark on America’s 195th spacewalk, venturing outside of the ISS to make some basic repairs, including retracting a part of the station’s cooling system, a task that has been on the to-do list of spacewalker’s for a while now. The two will also install a new high-definition camera on the outside of the ISS.
