The National Aeronautics and Space Administration's Electrojet Zeeman Imaging Explorer (EZIE) mission has passed on to the construction phase after a rigorous review for design cleared the project for further development. Under the EZIE mission, scientists will study electrical currents in the uppermost limits of Earth's atmosphere which will solve the mystery of electrojets' structure and evolution. The mission will see three identical CubeSats orbiting the Earth in a pearls-on-a-string formation, being launched no…

By Vanessa Thomas, NASA’s Goddard Space Flight Center July 11, 2022This illustration shows the three CubeSats of NASA’s EZIE mission flying in formation above Earth. The spacecraft will study electrical currents in Earth’s atmosphere that link changes in the magnetosphere to effects at the Earth’s surface during geomagnetic storms – the same storms that trigger the colorful auroral displays.

When Guillermo Mejias was 7 years old, his parents sent him out to buy bread during a family holiday in southern Spain. Mejias still remembers his growing anxiety as he walked to the bakery, repeating what he would say over and over in his head. But when the moment arrived, he was unable to produce a single word. He recalls returning empty-handed, ashamed, and wondering what to tell his parents. “I was so tense that I had been inadvertently biting my cheeks and tongue and my mouth…

Mathematicians have discovered that moiré patterns formed by rotating and stretching one lattice relative to another may be used to design a variety of composite materials. Their electrical and other physical characteristics can change—sometimes dramatically—depending on whether the resultant moiré patterns are regularly repeating or non-repeating.You’re probably familiar with moiré patterns, the large-scale interference patterns known in mathematics, physics, and art. They are created by overlaying one ruled opaque…

A flexible contact lens that senses eye pressure and releases a drug on-demand could help treat glaucoma, the second leading global cause of blindness worldwide.The compact wireless device, which has been developed by a team of Chinese researchers and tested in pig and rabbit eyes so far, appears to detect and reduce rising eye pressure, one of the usual causes of glaucoma.  Glaucoma is an umbrella term for a group of eye diseases where damage to the optic nerve, which relays visual information to the brain, causes…

Bacteria producing nanowires made up of cytochrome OmcS. Credit: Ella Maru StudioCooling Speeds Up Electrons in Bacterial NanowiresThe ground beneath our feet and under the ocean floor is an electrically-charged grid created by bacteria “exhaling” excess electrons through tiny nanowires in an oxygen-depleted environment.

Conductive structures at depths between 28 and 39 km, corresponding to the lower crust and uppermost mantle, colored by density anomaly. Red indicates below average density at this depth indicating a liquid conductive phase, blue indicates neutral to above average density, associated with a solid conductive phase or dry melt. The location of the Yellowstone Hotspot is marked by a yellow star. Credit: Geophysical Research Letters (2022). DOI:…

Jeep has gone all in on its annual raft of Easter Jeep Safari concepts this year, dazzling the Moab 4x4 crowd with what it defines as its most impressive lineup of Safari concepts ever. Its slogan "Zero Emissions Freedom" helps shape the concept slate, which is headlined by a ferocious evolution of last year's Wrangler Magneto. The Magneto 2.0 emerges as an absolute off-road tour de force, developing up to 625 hp and 850 lb-ft of torque for everything from slow-motion, high-consequence rock crawling to furious two-second…
