From 1975 on, the global surface ocean has shown a pronounced-though wavering-warming trend. Starting in 2004, however, that warming seemed to stall. Researchers measuring the Earth's total energy budget-the balance of sunlight ...

(PhysOrg.com) -- It's been seven months since Italian physicists Andrea Rossi and Sergio Focardi publicly demonstrated a device that they claimed could generate large amounts of excess heat through some kind of low-energy ...
In the center of most galaxies lies a supermassive black hole. Some of these are actively feeding on the gas and dust around them, expelling excess energy as powerful jets that are seen as quasars across the entire observable ...
