Impossible Foods has been granted approval by the FDA to sell its plant-based meat in US groceries this fall. The additive in Impossible Burgers that gives it a meat-like flavor and makes it 'bleed', soy leghemoglobin, has been deemed safe for consumers to eat. Competitor Beyond Meat already sells its plant-based meat products in grocery stores, recently selling out at some Whole Foods locations. Currently, consumers can only purchase Impossible Foods' fake meat at partnered restaurants, including Burger King, Qdoba, and Claim Jumper. The demand for meat alternatives is likely to grow as people become more health-conscious.

Spanish-born biologist Juan Carlos Izpisúa Belmonte, who operates a lab at the Salk Institute in California, has been working with researchers in China to create embryos that are part human and part monkey. The aim is to research human-animal chimeras for viability in organ transplants. Previous research into other types of human-animal chimeras has failed as the human cells were far too different from other animals' cells. While harvesting organs from human-monkey chimeras is probably not a viable option due to their size and how long they take to develop, the research may provide clues to crossing evolutionary barriers when creating other types of chimeras. So far, no human-monkey chimeras have been born, as they are only allowed to develop for up to two weeks in the lab. There are no rules for creating mixed human-monkey embryos in China.

NASA's Artemis program is a collaboration between NASA and 13 private US companies with the aim of taking humans back to the Moon by 2024. SpaceX will be part of the Artemis program, developing technologies that will help spacecraft refuel while in orbit. Pulling away from Earth's gravity is typically where most fuel is used, so being able to refuel a spacecraft while in space would greatly improve the efficiency and range of space travel.
