Using historical radar data to map changes in urban environments
Synthetic aperture radar (SAR) is a type of remote sensing from satellites that uses the reflection of radio waves to relay information about the surface of the earth. This reflection, or backscatter, is responsive to physical properties, such as rou.....»»
Observations confirm plasma bubble origin of persistent radio emissions from fast radio bursts
Fast Radio Bursts (FRBs) are one of the most recent open mysteries of modern astrophysics. Within a few milliseconds, these powerful events release an immense amount of energy, among the highest observable in cosmic phenomena......»»
Middle-aged radicalization: Why are so many of Britain"s rioters in their 40s and 50s?
Look closely at the pictures of the violent unrest that has spread across England and Northern Ireland and you will notice something that is not being spoken about. The rioters seen fighting, attacking police and setting fire to buildings are often m.....»»
Coupling excitons to polaritons for better solar cells and higher intensity LEDs
In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and thos.....»»

Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
How solar panels went from ’50s satellites to your backyard
From Einstein's theories of light to Bell Lab's revelations about doping silicon, solar power has been inching toward its current craze for more than a century. Here's how we got here......»»

Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
A new study shows how the sun could permanently capture rogue planets
Interest in interstellar objects (ISOs) was ignited in 2017 when 'Oumuamua flew through our solar system and made a flyby of Earth. Roughly two years later, another ISO passed through our solar system—the interstellar comet 2I/Borisov......»»
