A new strategy to create blue light from a promising material

A Florida State University research team has developed a new way to create blue light from a class of materials that shows enormous potential for optoelectronic devices, including solar cells, light-emitting diodes (LEDs) ...

Identifying a new, cleaner source for white light

When early humans discovered how to harness fire, they were able to push back against the nightly darkness that enveloped them. With the invention and widespread adoption of electricity, it became easier to separate heat ...

Astronomers investigate a peculiar cataclysmic variable

Using ESA's XMM-Newton satellite, astronomers from the Columbia University in New York have inspected a peculiar cataclysmic variable system known as Swift J0503.7−2819. Results of the study, presented June 29 on arXiv.org, ...

Webb telescope to reveal earliest galaxies after Big Bang

NASA's James Webb Space Telescope is poised to reveal some of the earliest galaxies that formed after the Big Bang, the White House said Monday, as anticipation builds for the powerful observatory's first images.

Sizing up special light to downsize particle accelerators

Researchers have developed a new technique to better measure special "terahertz" light. This light travels in waves longer than the infrared light that is beyond what the human eye perceives. The new sampling technique preserves ...

Astronomers discover two new polars

By analyzing the data from the Spektr-RG (SRG) space observatory and from the Zwicky Transient Facility (ZTF), astronomers from the California Institute of Technology (Caltech) and elsewhere have discovered two new polars. ...

Astronomers investigate highly variable polar V496 UMa

By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...

Light-emitting electrochemical cells for recyclable lighting

A low-cost and easy-to-manufacture lighting technology can be made with light-emitting electrochemical cells. Such cells are thin-film electronic and ionic devices that generate light after a low voltage is applied. Researchers ...
