Stellar explosions forge heavy elements such as gold more quickly than scientists had predicted, as indicated by the first measurement of the half-life of a rare form of nickel that's a key link in the chain of element formation. (p. 318)
-
Studies that fail to find purported five-quark particles, or pentaquarks, are stacking up quicker than studies that claim to have found such particles, suggesting that they might not really exist. (p. 318)
