Polarized light pollution leads animals astray

Human-made light sources can alter natural light cycles, causing animals that rely on light cues to make mistakes when moving through their environment. In the journal Frontiers in Ecology and the Environment, a collaboration ...

Atomic-scale investigations solve key puzzle of LED efficiency

(Phys.org) —From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs—and ...

NRL develops low cost, high efficiency solar sensor

Research scientists at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division have developed a novel low cost, highly efficient spectral sensor for field analysis of solar cell irradiance performance ...

Picturing access to energy for all in sub-Saharan Africa

The U.N.'s Sustainable Development Goal 7 (SDG 7) aims to ensure access to affordable, reliable, sustainable and modern energy for all populations by 2030. Access to electricity services is, of course, a key priority under ...

AI helps scientists understand cosmic explosions

Scientists at the University of Warwick are using artificial intelligence (AI) to analyze cosmic explosions known as supernovae. Their paper is published in Monthly Notices of the Royal Astronomical Society.

Light amplification accelerates chemical reactions in aerosols

Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify ...

Massive stellar winds are made of tiny pieces

(Phys.org)—ESA's XMM-Newton space observatory has completed the most detailed study ever of the fierce wind from a giant star, showing for the first time that it is not a uniform breeze but is fragmented into hundreds of ...

Organic electronics—a hot matter

Organic semi-conductors could revolutionise electronics in various areas. Nowadays, components put out such high performances that they are used in small devices like mobile phones. With larger devices, however, the organic ...
