[Image of fire-ant raft] A team led by Nathan Mlot, a doctoral student studying bio-inspired engineering at Georgia Institute of Technology, collected fire ants by roadsides in Atlanta and then filmed and froze the ants when they formed these floating clusters. [Fire Ants Go Global] Once ...
each other,forming a floating disk atop the water.The antraft may float for months seeking safe harbor.The ants on the bottom don't drown,and the ants on the top stay dry.Working together,the ants float to safety---even though a single ant alone in the water will struggle to survive....
mounted a large container of water on top of an old record player (spin table), with a small ant raft floating on the water's surface. In one experiment, both the container and the raft were spinning. In another, the researchers created a vortex in the water with a magnetic st...
But the ant structures are a combination of solid and fluid when stressed by forces at all speeds, the researchers found. They actively deform their structure to accommodate a stress (like a fluid) but then bounce back into place afterward (like a solid). Check out what happens w...

A drop of water can sit on top of the ant like a backpack. When an ant does end up underwater, tiny hairs on its body can trap bubbles of air that give the bug a boost up.To investigate the science behind the antraft, the scientists placed hundreds or thousands of ants at a time...
Hello all, I've used physicsforums a few times over the years, but I believe this is my first post. I'm working on an engineering project in which I need to find a highly-endothermic reaction where the reactants and products will be stable at very high temperatures (well over 800C)...
When there is floating coal in the roadway with poor ventilation, spontaneous combustion may occur. Moreover, a coal dust explosion can be caused by a gas explosion, electrical equipment detonation, friction sparks, impact sparks, a fire caused by electric welding, and spontaneous coal combustion....

mixed condition of reactants. The fact that even a partial restriction of an explosive dust cloud might generate a very devastating explosion should be taken into consideration. Dust clouds act similarly to combustible gas clouds in this respect as well. View chapter ...
