Published Chloride ions from seawater eyed as possible lithium replacement in batteries of the future
(via sciencedaily.com) 
Sodium, Potassium and zinc have all been promising contenders for lithium's place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.
Published Webb reveals colors of Earendel, most distant star ever detected
(via sciencedaily.com) 
NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. Webb's NIRCam (Near-Infrared Camera) instrument reveals the star to be a massive B-type star more than twice as hot as our Sun, and about a million times more luminous.
Published Quantum material exhibits 'non-local' behavior that mimics brain function
(via sciencedaily.com) 
New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Geomagnetic field protects Earth from electron showers
(via sciencedaily.com)
Original source 
Geophysicists studied the activity of high energy electrons and clarified the unexpected protective role of the geomagnetic field surrounding the Earth.
Published Gas streamers feed triple baby stars
(via sciencedaily.com)
Original source 
New observations and simulations of three spiral arms of gas feeding material to three protostars forming in a trinary system have clarified the formation of multi-star systems.
Published Single drop of ethanol to revolutionize nanosensor manufacture
(via sciencedaily.com) 
Engineers have developed a breakthrough technique to make the processing of nanosensors cheaper, greener and more effective by using a single drop of ethanol to replace heat processing of nanoparticle networks, allowing a wider range of materials to be used to make these sensors.
Published Scientists discover the highest-energy light coming from the sun
(via sciencedaily.com) 
New research details the discovery of the highest-energy light ever observed from the sun. The international team behind the discovery also found that this type of light, known as gamma rays, is surprisingly bright. That is, there's more of it than scientists had previously anticipated.
Published New exoplanet discovery builds better understanding of planet formation
(via sciencedaily.com) 
An international team of scientists have discovered an unusual Jupiter-sized planet orbiting a low-mass star called TOI-4860, located in the Corvus constellation.
Published James Webb Space Telescope captures stunning images of the Ring Nebula
(via sciencedaily.com) 
NASA's James Webb Space Telescope has recorded breath-taking new images of the iconic Ring Nebula, also known as Messier 57.
Published Mussel-inspired membrane can boost sustainability and add value to industrial wastewater treatment
(via sciencedaily.com) 
Engineers have developed a new kind of membrane that separates chemicals within wastewater so effectively that they can be reused, presenting a new opportunity for industries to improve sustainability, while extracting valuable by-products and chemicals from wastewater.
Published Gravitational arcs in 'El Gordo' galaxy cluster
(via sciencedaily.com) 
A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.
Published Faster thin film devices for energy storage and electronics
(via sciencedaily.com) 
An international research team reported the first realization of single-crystalline T-Nb2O5 thin films having two-dimensional (2D) vertical ionic transport channels, which results in a fast and colossal insulator-metal transition via Li ion intercalation through the 2D channels.
Published Cracking in lithium-ion batteries speeds up electric vehicle charging
(via sciencedaily.com) 
Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.
Published Energy-storing supercapacitor from cement, water, black carbon
(via sciencedaily.com) 
Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
Published Scientists create novel approach to control energy waves in 4D
(via sciencedaily.com) 
Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published Hubble sees evaporating planet getting the hiccups
(via sciencedaily.com) 
A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.
Published Listen to a star 'twinkle'
(via sciencedaily.com)
Original source 
Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.
Published Using cosmic weather to study which worlds could support life
(via sciencedaily.com) 
As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away exoplanets.
Published Webb snaps highly detailed infrared image of actively forming stars
(via sciencedaily.com)
Original source 
Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.
