Asteroid discovery suggests ingredients for life on Earth came from space
Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago. Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency's Hayabusa2 spacecraft from two sites on Ryugu in 2019. Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Niacin, also called Vitamin B3 or nicotinic acid, is vital for their metabolism.
Second lab-grown chicken product cleared for human consumption by U.S. regulator
California-based cultivated meat company GOOD Meat has received clearance from the U.S. Food and Drug Administration to bring its lab-grown chicken to market, according to agency documents released on Tuesday. Several companies are working to bring cultivated meat to market in the United States, and must receive approval from both the FDA and the U.S. Department of Agriculture before they can sell their products.
