Image: Hubble views a galaxy with an active black hole

This image from the NASA/ESA Hubble Space Telescope reveals tendrils of dark dust threading across the heart of the spiral galaxy NGC 7172. The galaxy lies approximately 110 million light-years from Earth in the constellation ...

Researchers discover anti-laser masquerading as perfect absorber

Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber ...

UCLA scientists double efficiency of novel solar cell

Nearly doubling the efficiency of a breakthrough photovoltaic cell they created last year, UCLA researchers have developed a two-layer, see-through solar film that could be placed on windows, sunroofs, smartphone displays ...

Researchers make magnetic fields breakthrough

(PhysOrg.com) -- Researchers at the University of Dundee have made a breakthrough in the study of magnetic fields, which enhances our understanding of how stars, including the Sun, work.

43 percent: New solar power world record

(PhysOrg.com) -- Australian and US solar cell researchers have achieved the highest efficiency for solar power, setting a new world record of 43 per cent of sunlight converted into electricity.

Ice-like phonons in liquid water discovered

For more than 100 years, scientists have debated what the underlying molecular structure of water is, and the common view has been that H2O molecules are either "water-like" or "ice-like." Now through computer simulation ...

Solving the solar cell power conversion dilemma

(PhysOrg.com) -- "There is a lot of interest in creating more efficient solar cells that are also simpler than many of the designs common now," Wladek Walukiewicz tells PhysOrg.com. "We think that, through the mixing of certain ...

Comparing energy conversion of plants and solar cells

Scientists now have a way to more accurately compare how efficiently plants and photovoltaic, or solar, cells convert sunlight into energy, thanks to findings by a research consortium that included a U.S. Department of Agriculture ...
