Lightening data have more use than previously thought

IMAGE: The lightning strokes light up the night sky with various shapes. view more  Credit: Zhichao Wang Lightning is a spectacular natural phenomenon and the fascination with thunderstorms and lightning is a long-standing one. Today, lightning is known to be closely associated with the electrification and discharge of thunderstorms. Different types of thunderstorms correspond to different lightning characteristics and charge structures. But what are the characteristics…

Flaring, massively

Its lower temperature makes it a prime target to study flares and the more explosive 'superflare' view more  Credit: National Astronomical Observatory of Japan Japan -- The cold, dark chaos of space is filled with mystery. Fortunately, the ways in which we can peer into the mists of the void are increasing, and now…

New biomaterial could shield against harmful radiation

IMAGE: Human cells treated with selenomelanin nanoparticles view more  Credit: Northwestern University EVANSTON, Ill.-- Packing for outer space? Here's one thing you won't want to forget. Northwestern University researchers have synthesized a new form of melanin enriched with selenium. Called selenomelanin, this new biomaterial shows extraordinary promise as a shield for human tissue against harmful radiation. "Given the increased interest in space travel, and the general…

New study shows colliding neutron stars may unlock mysteries of universe...

ORLANDO, July 8, 2020 - The National Science Foundation's Arecibo Observatory in Puerto Rico has proven itself instrumental in another major astronomical discovery. An international team of scientists, led by the University of East Anglia in the United Kingdom, found an asymmetrical double neutron star system using the facility's powerful radio telescope. This type of star system is believed to be a precursor to merging…

Shock-dissipating fractal cubes could forge high-tech armor

IMAGE: Simulations show how fractal structures of increasing complexity dissipate energy from shockwaves. view more  Credit: Los Alamos National Laboratory Tiny, 3D printed cubes of plastic, with intricate fractal voids built into them, have proven to be effective at dissipating shockwaves, potentially leading to new types of lightweight armor and structural materials effective against explosions and impacts. "The goal of the work is to manipulate the…
