(PhysOrg.com) -- Four theoretical physicists, led by Allan Widom, of Northeastern University, have published a paper in arXiv, where they show a possible way for some bacteria to produce radio waves. Taking note of the fact ...
(Phys.org)—Energy from the ocean, or "blue energy," is arguably the most underexploited power source, according to researchers in a new study. Although the oceans contain enough energy to meet all of the world's energy ...
(PhysOrg.com) -- Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the ...

(Phys.org)—Physicists have demonstrated a new mode of electromagnetic wave called a "line wave," which travels along an infinitely thin line along the interface between two adjacent surfaces with different electromagnetic ...
(PhysOrg.com) -- At the Clean Technology 2011 Conference and Expo in Boston, Andre Sharon presented a new concept of using ships equipped with a wave-power system to harvest energy and deliver it back to a power grid on shore.
(Phys.org) —With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip ...
