Published How to slow the spread of deadly 'superbugs'
(via sciencedaily.com) Original source Harnessing new advances in genomic surveillance technology could help detect the rise of deadly 'superbugs'.
Published Researchers capture first images of a radio 'ring of fire' solar eclipse
(via sciencedaily.com) Original source Researchers have recorded images of a solar eclipse with the 'ring of fire' effect in radio waves.
Published Gut fungi's lasting impact on severe COVID-19 immune response
(via sciencedaily.com) Original source Certain gut-dwelling fungi flourish in severe cases of COVID-19, amplifying the excessive inflammation that drives this disease while also causing long-lasting changes in the immune system, according to a new study. This discovery identifies a group of patients who may benefit from specialized, but yet-to-be determined treatments.
Published Superdeep diamonds provide a window on supercontinent growth
(via sciencedaily.com) Original source Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research. These findings demonstrate that superdeep diamonds can provide a window through space and time into the supercontinent growth and formation process.
Published Researchers probe molten rock to crack Earth's deepest secrets
(via sciencedaily.com) Original source An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its magnetic behavior and reactivity in chemical reactions, and can influence whether iron prefers to be in the molten or solid rock.
Published Discovery finds ferns produce crop-saving insecticide
(via sciencedaily.com) Original source Researchers have solved the structure of a novel insecticidal protein that is effective in protecting major crop plants like corn and soybean from pests and is naturally produced by ferns.
Published Researchers probe how a piece of the moon became a near-Earth asteroid
(via sciencedaily.com) Original source Two years after the striking discovery that a near-Earth asteroid could be a chunk of the moon, another UArizona research group has found that a rare pathway could have enabled this to happen.
Published Researchers create the most water-repellent surface ever
(via sciencedaily.com) Original source A revised method to create hydrophobic surfaces has implications for any technology where water meets a solid surface, from optics and microfluidics to cooking.
Published LIGO surpasses the quantum limit
(via sciencedaily.com) Original source Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO.
Published Climate is increasing risk of high toxin concentrations in Northern US lakes
(via sciencedaily.com) Original source As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.
Published Plants transformed into detectors of dangerous chemicals
(via sciencedaily.com) Original source What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
Published Plant-based materials give 'life' to tiny soft robots
(via sciencedaily.com) Original source A team of researchers has created smart, advanced materials that will be the building blocks for a future generation of soft medical microrobots. These tiny robots have the potential to conduct medical procedures, such as biopsy, and cell and tissue transport, in a minimally invasive fashion.
Published Simulating cold sensation without actual cooling
(via sciencedaily.com) Original source The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature.
Published Adaptive optical neural network connects thousands of artificial neurons
(via sciencedaily.com) Original source Physicists working with computer specialists have developed a so-called event-based architecture, using photonic processors. In a similar way to the brain, this makes possible the continuous adaptation of the connections within the neural network.
Published Unexpected behavior discovered in active particles
(via sciencedaily.com) Original source Physicists have now shown that, depending on the extent to which the propulsion speed of active particles is dependent on their orientation, clusters in different shapes arise in many-particle systems. This might be a possible key to the realization of programmable matter.
Published Probiotics delivered in biofilm state protect the intestines and brain in NEC model
(via sciencedaily.com) Original source Researchers have been working on a novel solution to prevent NEC. They have developed a novel probiotic system that harnesses the durability of biofilms to improve the administration of probiotics to patients. Their latest study describes the use of a biofilm formulation of Limosilactobacillus reuteri (Lr) to prevent NEC in a piglet model.
Published Mimics human tissue, fights bacteria: New biomaterial hits the sweet spot
(via sciencedaily.com) Original source A new lab-made substance mimics human tissue and could reduce or replace the use of animal-derived materials in biomedical research.
Published Fungal evolution discovered: Mycena can now invade living hosts
(via sciencedaily.com) Original source Biologists have long known mushrooms of the genus Mycena, commonly known as bonnet mushrooms, as fungi that live off of dead trees and plants. New research demonstrates that bonnets can also find their ways into young, healthy trees and plants, where they try to cooperate. In doing so, they have made an evolutionary leap which challenges our understanding of the ecological roles of fungi.
Published A step on the way to solid-state batteries
(via sciencedaily.com) Original source A lithium ceramic could act as a solid electrolyte in a more powerful and cost-efficient generation of rechargeable lithium-ion batteries. The challenge is to find a production method that works without sintering at high temperatures. A research team has now introduced a sinter-free method for the efficient, low-temperature synthesis of these ceramics in a conductive crystalline form.
Published Chemists, engineers craft adjustable arrays of microscopic lenses
(via sciencedaily.com) Original source A team has created minuscule lenses that it can expand or contract in mere seconds -- modifying their magnification, focal length and other optical properties in the process. That on-the-fly adaptability bodes well for the design's use in micro-projection systems and even the culturing of cells, the researchers said.
