Insect mating behavior has lessons for drones

Male moths locate females by navigating along the latter’s pheromone (odor) plume. Two strategies are involved: males must find the outer envelope of the pheromone plume, and then head upwind. Can understanding such insect behavior be useful for robotics research? Yes, according to an entomologist, whose research using computer simulations shows that such insect behavior has implications for airborne robots (drones) that ply the sky searching for signature odors.

Some gas produced by hydraulic fracturing comes from surprise source

Some of the natural gas harvested by hydraulic fracturing operations may be of biological origin — made by microorganisms inadvertently injected into shale by oil and gas companies during the hydraulic fracturing process, a new study has found.

Satellites find sustainable energy in cities

Underground heat islands in cities have an enormous geothermal potential. Warm groundwater can be used to produce sustainable energy for heating and cooling. Researchers have now developed a new method to find underground heat islands: They estimate groundwater temperature from surface temperatures and building densities measured by satellites.
