...article type. It's a sort of field theory for the infinite
tower of oscillatory modes of a string, each of them representing different particle species, Schnabl said. As Schnabl observed, string field theory, by explaining also how quantum mechanics is compatible with general relativity, is essential for und...

number of "degrees of freedom"--the octopus is able to generate a vast repertoire of movements that is unmatched by the human arm. Nonetheless, despite the huge evolutionary gap and morphological differences between the octopus and vertebrates, the o...

Computer modeling reveals hidden conversations within cells
...ws that, analogous to how a telephone transmits an infinite
number of different signals along a single wire, it is the timing of the proteins' activity that allows them to exert intricate control over the behavior of a cell. The computer model reveals the hidden conversations in the cell's wiring." The resea...

universe of "probe-like" small chemical compounds that might possibly modulate these interactions. But what would be most useful to know for any one disease is which particular human molecules are interacting and which exact type of smal...
