Meet the ‘Halo 4’ Engineers Delivering ‘30 Seconds of Fun’ – Early and Often

“Halo 4” launches tomorrow, and millions of fans will start blasting their way through the biggest and most detailed “Halo” universe yet.

REDMOND, Wash. — Nov. 5, 2012 — It happens early and often in every “Halo” game: the ‘30 seconds of fun.’

That phrase refers to the heart-thumping period when players risk pixelated life and limb to take on teeming hordes of enemies. The ‘30 seconds of fun’ mantra began with Bungie, the game studio that created the first five games of the “Halo” franchise.

But “Halo” has always delivered a rich story alongside the action; the game’s universe has spawned comic books and New York Times bestselling novels. “Halo” takes the Goldilocks approach to gaming: it doesn’t exhaust you with long storytelling animations nor numb you with nonstop battles. It finds a middle ground: It’s just right. (more…)

Researchers Find ‘Goldilocks’ of DNA Self-Assembly

Researchers from North Carolina State University have found a way to optimize the development of DNA self-assembling materials, which hold promise for technologies ranging from drug delivery to molecular sensors. The key to the advance is the discovery of the “Goldilocks” length for DNA strands used in self-assembly – not too long, not too short, but just right.

DNA strands contain genetic coding that will form bonds with another strand that contains a unique sequence of complementary genes. By coating a material with a specific DNA layer, that material will then seek out and bond with its complementary counterpart. This concept, known as DNA-assisted self-assembly, creates significant opportunities in the biomedical and materials science fields, because it may allow the creation of self-assembling materials with a variety of applications.

But, while DNA self-assembly technology is not a new concept, it has historically faced some significant stumbling blocks. One of these obstacles has been that DNA segments that are too short often failed to self-assemble, while segments that are too long often led to the creation of deformed materials. This hurdle can lead to basic manufacturing problems, as well as significant changes in the properties of the material itself. (more…)
