(PhysOrg.com) -- Acting as a microscope for sound, a new device called a micro-ear could make objects on the micro-scale audible. The device could enable scientists to listen to the sounds that cells and bacteria make as ...
(PhysOrg.com) -- "Scientists have been working with dipole fields for quite some time," Peter Barker tells PhysOrg.com. "However, most of the work is focused on very small particles, like atoms, or on larger particles, such ...
Biofilms—slimy layers formed when bacteria stick together on a surface—allow bacteria to shield themselves from extreme environments and even evade antibiotics. In a new study, researchers have shown that laser light ...
