   All it’s doing is minimizing its surface area. Even non-living things can do that (think of a droplet of oil immersed in water).

   They do bring up the point that people refer to “intelligent materials”, but I think the study does more to show the ridiculousness of that label rather than the actual intelligence of the slime mold. “Smart materials” or “responsive materials” would perhaps be better.

   By George, are you saying there is intelligent oil out there?

   Plants can re-orient themselves to get more sunlight too, but I wouldn’t call that intelligence. Putting the slime mold in a maze seems misleading.

   Silliness.
   If a plant is placed in the same maze, with nutrients at one end, it would be intelligent? Its roots would fill out the same maze, and in the end, the root that finds the nutrients would grow the strongest. Same result.

   Am I missing something?

   It didn’t solve the maze, it just expanded to every possible pathway. If it had gone straight from one end to the other, that would’ve been intelligence, possibly.

   All it did was pull back the parts of it that weren’t most connected to the nutrient sources, to which it was apparently connected at the start and end of maze. Now, if it had grown from one end to the end to get the nutrients, that’d be impressive.

   I agree with commenters. Also, did it ‘pull back’ from non-nutrient paths, or did the cells in that chain just die off from not being fed?

   In any case, it’s just doing it’s thing, growing toward a food source. If you consider that intelligent, then we must consider a whole bunch of things ‘intelligent’, like DNA and virii, various internal organs, all types of plants and stuff.

   Putting something in a maze is a poor test for this kind of thing, i think. Why do so many ’scientists’ think maze=smart? bah!

    and those that are asleep and are dreaming may have pretty intelligent dreams… but they’re not conscious.

    Slime molds are freaking awesome. I had one in my back yard about a year ago and it was just fascinating. If I would have encountered one of those in my experiment-on-everything-you-can-find-in-the-back-yard preteen years, I would have had days of fun with that thing. If you haven’t already, look up slime molds on wikipedia.

    Okay, comment posted twice, sorry about that. The first one didn’t show up so I thought it didn’t post for some reason.
