(PhysOrg.com) -- Falling raindrops produce friction as they drop through the atmosphere to the ground, and this dissipates the kinetic energy, converting it into diffuse heat. Now researchers in the US have used recently-obtained ...
Rainfalls are suspected to trigger the spread of a multitude of foliar (leaf) diseases, which could be devastating for agriculture and forestry. Instead of focusing on the large-scale, ecological impact of this problem, researchers ...
