Published 'Inkable' nanomaterial promises big benefits for bendable electronics
(via sciencedaily.com) An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published Galaxy changes classification as jet changes direction
(via sciencedaily.com) A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.
Published High-energy-density, long life-cycle rechargeable lithium metal batteries
(via sciencedaily.com) Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes.
Published ESO telescopes on the aftermath of DART's asteroid impact
(via sciencedaily.com) Using ESO's Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA's Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid's composition from the expelled material.
Published Nitrate can release uranium into groundwater
(via sciencedaily.com) A team has experimentally confirmed that nitrate, a compound common in fertilizers and animal waste, can help transport naturally occurring uranium from the underground to groundwater. The new research backs a previous study showing that aquifers contaminated with high levels of nitrate -- including the High Plains Aquifer residing beneath Nebraska -- also contain uranium concentrations far exceeding a threshold set by the Environmental Protection Agency. Uranium concentrations above that EPA threshold have been shown to cause kidney damage in humans, especially when regularly consumed via drinking water.
Published Scientists find a common thread linking subatomic color glass condensate and massive black holes
(via sciencedaily.com) Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.
Published Recycling: Researchers separate cotton from polyester in blended fabric
(via sciencedaily.com) Researchers found they could separate blended cotton and polyester fabric using enzymes -- nature's tools for speeding chemical reactions. Ultimately, they hope their findings will lead to a more efficient way to recycle the fabric's component materials, thereby reducing textile waste.
Published Can synthetic polymers replace the body's natural proteins?
(via sciencedaily.com) Scientists developing new biomaterials often try to mimic the body's natural proteins, but a chemist shows that simpler polymers -- based on a handful of plastic building blocks -- also work well. Using AI, her team was able to design polymer mixtures that replicate simple protein functions within biological fluids. The random heteropolymers dissolve and stabilize proteins and can support cells' normal protein-making machinery. The technique could speed the design of materials for biomedical applications.
Published Cans or bottles: What's better for a fresh, stable beer?
(via sciencedaily.com) The flavor of beer begins to change as soon as it's packaged, prompting a debate among afficionados: Does the beverage stay fresher in a bottle or a can? Now, researchers report that the answer is, well, complicated, and depends on the type of beer. An amber ale stayed fresher in bottles, whereas container choice made much less difference to the stability of an India Pale Ale (IPA).
Published Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
Published Nano cut-and-sew: New method for chemically tailoring layered nanomaterials could open pathways to designing 2D materials on demand
(via sciencedaily.com) A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials -- like a tailor altering a suit -- could be just the tool for designing the technology of a sustainable energy future. Researchers have developed a method for structurally splitting, editing and reconstituting layered materials, called MAX phases and MXenes, with the potential of producing new materials with very unusual compositions and exceptional properties.
Published 'Terminator zones' on distant planets could harbor life
(via sciencedaily.com) In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.
Published New approach to harvesting aerial humidity with organic crystals
(via sciencedaily.com) Researchers have reported a novel method of harvesting water from naturally occurring sources such as fog and dew.
Published Modelling superfast processes in organic solar cell material
(via sciencedaily.com) In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.
Published Evidence that Venus is volcanically active
(via sciencedaily.com) Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.
Published Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
(via sciencedaily.com) Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
Published Filming proteins in motion
(via sciencedaily.com) Proteins are the heavy-lifters of biochemistry. These beefy molecules act as building blocks, receptors, processors, couriers and catalysts. Naturally, scientists have devoted a lot of research to understanding and manipulating proteins.
Published Where did Earth's water come from? Not melted meteorites, according to scientists
(via sciencedaily.com) A new study brings scientists one step closer to answering the question of where Earth's water came from.
Published Researchers control the degree of twist in nanostructured particles
(via sciencedaily.com) Micron-sized 'bow ties,' self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team has shown.
Published Extensive catalog of exploding stars
(via sciencedaily.com) The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data is publicly available via the Young Supernova Experiment (YSE).
