Extreme heat wave to hit US - expected temperatures above 48 °C [1]

The Watchers, 6/29/13, Chillmanjaro

Interior US West will experience heat reaching dangerous levels, challenging records and elevating the wildfire threat. The developing pattern will take the heat to the extreme levels with record highs. Temperatures will soar above 120 °F (48.8 °C) into early next week. The extreme heat is expected to impact Las Vegas, Phoenix, Salt Lake City, Denver, Boise, Idaho, Rawlins, Medford and Fresno. The worst of the heat will hold up just inland over California.

Scientists discover highly asymmetric and branched patterns are the result of physical forces and local instabilities; research has important implications for understanding biofilms and multicellular systems.

hey showed that as each bacterium grows in a single direction, lines or files of cells are formed, but these files are unstable to small disturbances. As large numbers of cells push and shove against each other, mechanical instability leads to buckling and folding of cell files. This is repeated as the cells continue to grow and divide, leading to the formation of rafts of aligned cells arranged in self-similar branching patterns, or fractals.

These microscopic fractal patterns emerge spontaneously from physical interactions between the large number of cells within the population. This was tested by looking at the interactions between twin cell populations and a mutant [4] that has a round shape (where this behaviour is not observed).

espite [5] always forming circular shapes as they grow, their cells form internal divisions which are highly asymmetrical and branched. These fractal (self-similar) patterns are due to the physical forces and local instabilities that are a natural part of bacterial cell growth, a new study reveals. The research, published in the scientific journal ACS Synthetic Biology, has important implications for the emerging field of synthetic biology.
