Nuclear physics: Elusive transition spotted in thorium
The highly precise atomic clocks used in science and technology are based on electronic transitions in atoms. The discovery of a nuclear transition in thorium-229 raises hopes of making nuclear clocks a reality. See Article p.47

Nuclear physics: Four neutrons together momentarily
A system of four neutrons known as the tetraneutron is a hypothetical state in nuclear physics. The report of evidence for the fleeting existence of this state has implications for research into neutron stars.

Nuclear DNA sequences from the Middle Pleistocene Sima de los Huesos hominins
A unique assemblage of 28 hominin individuals, found in Sima de los Huesos in the Sierra de Atapuerca in Spain, has recently been dated to approximately 430,000 years ago. An interesting question is how these Middle Pleistocene hominins were related to those who lived in the Late Pleistocene epoch, in particular to Neanderthals in western Eurasia and to Denisovans, a sister group of Neanderthals...
EMC2 revives its quest for nuclear fusion
After languishing in limbo for most of the last year, EMC2 Fusion Development Corp. says it’s back in business with an unorthodox concept for nuclear fusion power plants. The concept is variously known as Polywell fusion, inertial electrostatic confinement or magnetic cusp confinement.....
Hey, coders: Want to do nuclear fusion research? This crowdsource challenge gives you a chance
It’s not clear when fusion power will pay off, but there’s a way to earn a cool $ 20,000 in fusion research. And you don’t even have to be a plasma physicist or an energy entrepreneur. All you have...
Nuclear physics: Close encounters of the alpha kind
Breakthrough calculations of collisions between two helium nuclei pave the way to a quantitative understanding of how the elements carbon and oxygen were made in stars — and to improved models of stellar evolution. See Letter p.111
