(Phys.org) —A team of researchers from the U.S., the Netherlands, and Italy has found a way to detect and measure the exchange of volatile organic compounds (VOCs) in the atmosphere. In their paper published in the journal ...
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much-despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living ...
