A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts–both extremely luminous, distant objects–has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction of gamma-ray bursts than in the direction of quasars. Quasars are thought to be powered by accretion of material onto supermassive black holes…

Atomic-resolution structure of a ribozyme yields insights into RNA catalysis and the origins of life
Which came first, nucleic acids or proteins? This question is molecular biology’s version of the “chicken-or-the-egg” riddle. Genes made of nucleic acids (DNA or RNA) contain the instructions for making proteins, but enzymes made of proteins are needed to replicate genes. For those who try to understand how life originated, this once seemed an intractable…

UCSC physicists explore a boundary of their discipline in new book, Quantum Enigma
Quantum mechanics, one of the most successful theories in all of science, says some strange things about the fundamental nature of the world. For all practical purposes, physicists can and do ignore the bizarre implications of the theory and use the equations of quantum mechanics to understand atoms and stars and to create the marvels…
