(PhysOrg.com) -- Overhead transmission lines traverse thousands of kilometers, often crossing remote areas. Inspecting the often ageing lines and the vegetation near them is an important aspect of maintenance, but it can ...
(PhysOrg.com) -- "One of the most exciting things about this is that it gives us nice, clean control over the interaction between light and matter," William Kelly tells PhysOrg.com. "Our technique has the potential to give ...
Electromagnetic noise poses a major problem for communications, prompting wireless carriers to invest heavily in technologies to overcome it. But for a team of scientists exploring the atomic realm, measuring tiny fluctuations ...
