Why, in Superbowl of statistical mechanics, famous players could never cross goal line: 3-D proof for Ising model impossible, researcher proves

Computational biologist Sorin Istrail shows that the solution of Ising's model cannot be extended into three dimensions for any lattice, making exact solutions unattainable. The model, developed by Ernst Ising in 1926, has been extensively studied in one and two dimensions but remains unsolvable in three dimensions.

Nature's cycles in a fractal state of mind

Scientists Yonathan Shapir and Jacob Jorné discovered that natural cycles generate fractal patterns, governing everything from weather to cauliflower heads. This breakthrough enables the prediction of events like car battery lifespan, lawn growth, and tumor cell behavior, with potential applications in engineering and medicine.
