off to new pastures. All of my slime attempts were a bit off. A new study finds that some strains of this social amoeba, called, dictyostelium discoideum, pack bacteria snacks with them before they travel. The second time I attempted, I did the same thing only added the glue into the Borax, which also didnt mix very well. "We now know that primitively social slime molds have genetic variation in their ability to farm beneficial bacteria as a food source George Gilchrist, program director in the National Science Foundation's Division of Environmental Biology, which funded the research, said in a statement. A bit too gritty, a bit too liquidy, not sticky enough, not bouncy enough. It's a strategy that's not without costs. I never even did it right once after 5 tries. It all smelled like glue and made a mess of my hands. The process gave scientists an insight into how the mold deciphered, as a collective, which direction to hunt.

Dictyostelium biology could be summed up in a lyric of the rock band Metallica Boomsma, who was not involved in the study, wrote.

Oh, and don't forget to pack a lunch. Neither of them worked either. Researchers found the slime branches communicated with each other every minute by using their pulsing mechanism, which triggers the mold to pump out in the direction of a favorable environment. Though the amoebae don't plow, hoe, or otherwise tend their bacterial crop, the behavior is a form of primitive farming, Rice University researchers reported Jan. The institute has more than a year of experiments to conduct before it can release further results, but if initial testing has taught the team anything, its that intelligence doesnt have to be complicated: Decision making doesnt necessarily need complex communication mechanism, often just physics. The team conducted an timelapse experiment over a 24 to 48 hour period in which they filmed slime mold as it became hungry and spread out looking for sustenance. "If this farming symbiosis turns out to be ancient, our new understanding.
