Can planets be rejuvenated around dead stars?

For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow. Rejuvenated planets, as they are nicknamed, are only hypothetical. ...

3-D imaging provides window into living cells, no dye required

(Phys.org) —Living cells are ready for their close-ups, thanks to a new imaging technique that needs no dyes or other chemicals, yet renders high-resolution, three-dimensional, quantitative imagery of cells and their internal ...

Barn owls reflect moonlight in order to stun their prey

Ecosystems that are bathed in light during the day change profoundly at night. As the sun fades from the land, nocturnal life emerges, with the barn owl (Tyto alba) among them. Barn owls are iconic nocturnal birds of prey ...

Important step in understanding of light scattering

A team of researchers from the University of Twente and from Philips in the Netherlands has succeeded in taking an important step in understanding how light is scattered, absorbed and re-emitted in white light emitting diodes ...

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. ...

Engineers ride 'rogue' laser waves to build better light sources

A freak wave at sea is a terrifying sight. Seven stories tall, wildly unpredictable, and incredibly destructive, such waves have been known to emerge from calm waters and swallow ships whole. But rogue waves of light -- rare ...

Quantum dots brighten the future of lighting

(Phys.org) -- With the age of the incandescent light bulb fading rapidly, the holy grail of the lighting industry is to develop a highly efficient form of solid-state lighting that produces high quality white light.
