Lab-grown mammoth meat used to create giant meatball in startup's triumph.

An Australian cultured meat company, Vow, has created an oversize meatball using cultivated flesh in a lab, partly made from the DNA of an extinct woolly mammoth, to educate people on alternatives that are more sustainable than real meat. Meanwhile, a tornado in Mississippi killed at least 26 people, and President Joe Biden toured the ravaged area on March 31. In Nashville, three students and three adults were killed by a shooter at a private Christian school. On a lighter note, the MLB's Opening Day saw the Yankees crush the San Francisco Giants 5-0, with rookie shortstop Anthony Volpe making his major league debut.
