SpaceX’s Dragon spacecraft successfully arrived at the International Space Station on October 15, docking at 10:27 a.m. EDT with the space-facing port of the station’s Harmony module. The spacecraft brought more than 6,300 pounds of food, equipment, and other essential supplies for the Expedition 75 crew. The delivery marks SpaceX’s 35th commercial resupply mission to the orbiting laboratory under its contract with NASA. New Solar Arrays and Advanced Medical ResearchAmong the cargo is the final set of International Space Station Roll-Out Solar Arrays (IROSAs), which astronauts are expected to install later this fall. These arrays will expand the station’s ability to generate electricity from sunlight.

The sea cucumber study reveals an unusual form of tissue regrowth, with detached fragments continuing to heal, reorganize, and grow for more than three years in natural seawater. Credit: ShutterstockSea cucumber tissue kept growing for more than three years after removal, surviving in seawater teeming with microbes. Like Thing, the disembodied hand in The Addams Family, a severed piece of sea cucumber tissue kept living without the body it came from, prompting scientists to describe the animal as a “real-life zombie.” Weeks after being cut from a tube foot, the fragment appeared to be growing in seawater full of microbes, far from the sterile conditions usually needed to keep tissue cultures alive. Scientists at Memorial University of Newfoundland followed up by placing tissue removed from the feet, main body, and tentacles of three sea cucumbers in flowing seawater. The animals belonged to Psolus fabricii, a cold-water species. Working with collaborators including Rachel Sipler, a senior research scientist at Bigelow Laboratory for Ocean Sciences, the team documented what happened to those fragments in a study published in Science Advances.
