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).
Published 'Glow-in-the-dark' proteins could help diagnose viral diseases
(via sciencedaily.com) Despite recent advancements, many highly sensitive diagnostic tests for viral diseases still require complicated techniques to prepare a sample or interpret a result, making them impractical for point-of-care settings or areas with few resources. But now, a team has developed a sensitive method that analyzes viral nucleic acids in as little as 20 minutes and can be completed in one step with 'glow-in-the-dark' proteins.
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.
Published Webb Telescope captures rarely seen prelude to supernova
(via sciencedaily.com) The rare sight of a Wolf-Rayet star -- among the most luminous, most massive, and most briefly detectable stars known -- was one of the first observations made by NASA's James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.
Published 3D internal structure of rechargeable batteries revealed
(via sciencedaily.com) Researchers have pioneered a technique to observe the 3D internal structure of rechargeable batteries. This opens up a wide range of areas for the new technique from energy storage and chemical engineering to biomedical applications.
Published Thermal conductivity of metal organic frameworks
(via sciencedaily.com) Metal organic frameworks, or MOFs, are kind of like plastic building block toys. The pieces are simple to connect, yet they're capable of building highly sophisticated structures.
Published Scientists identify substance that may have sparked life on Earth
(via sciencedaily.com) A team of scientists dedicated to pinpointing the primordial origins of metabolism -- a set of core chemical reactions that first powered life on Earth -- has identified part of a protein that could provide scientists clues to detecting planets on the verge of producing life.
Published Customizing catalysts for solid-state reactions
(via sciencedaily.com) A newly developed molecular catalyst specifically tailored for mechanochemical reaction conditions enables high-efficiency transformations at near room temperature.
Published Researchers find access to new fluorescent materials
(via sciencedaily.com) Fluorescence is a fascinating natural phenomenon. It is based on the fact that certain materials can absorb light of a certain wavelength and then emit light of a different wavelength. Fluorescent materials play an important role in our everyday lives, for example in modern screens. Due to the high demand for applications, science is constantly striving to produce new and easily accessible molecules with high fluorescence efficiency.
Published Microscopy: Highest resolution in three dimensions
(via sciencedaily.com) Researchers have developed a super-resolution microscopy method for the rapid differentiation of molecular structures in 3D.
Published Scientists call for global push to eliminate space junk
(via sciencedaily.com) As almost 200 countries agree a legally-binding treaty to protect the High Seas, a collaboration of experts in ocean plastic pollution and satellite technology has urged world leaders to learn lessons from the management of the High Seas and act now to protect Earth's orbit.
Published New biosensor reveals activity of elusive metal that's essential for life
(via sciencedaily.com) A new biosensor offers scientists the first dynamic glimpses of manganese, an elusive metal ion that is essential for life.
Published A safe synthesis of hydrogen peroxide inspired by nature
(via sciencedaily.com) Scientists report the safe synthesis of hydrogen peroxide (H2O2), an oxidizing agent used in multiple industries including semiconductors, using a new rhodium-based catalyst. The catalyst is based on natural enzymes found in extremophile microorganisms, and the reaction meets three chemical ideals for H2O2 production: safe, use of a single vessel, and direct synthesis.
Published How does the immune system react to altered gravity?
(via sciencedaily.com) Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions. But is it also risky to be exposed to altered gravity for short periods of time?
Published Flat, pancake-sized metalens images lunar surface in an engineering first
(via sciencedaily.com) Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a research team created the first ultrathin, compact metalens telescope capable of imaging far-away objects, including the moon.
Published The planet that could end life on Earth
(via sciencedaily.com) A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.
Published Can artificial intelligence help find life on Mars or icy worlds?
(via sciencedaily.com) Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.
Published Catalyst purifies herbicide-tainted water and produces hydrogen
(via sciencedaily.com) Researchers have developed a dual-purpose catalyst that purifies herbicide-tainted water while also producing hydrogen.
Published DART impact provided real-time data on evolution of asteroid's debris
(via sciencedaily.com) When asteroids suffer natural impacts in space, debris flies off from the point of impact. The tail of particles that form can help determine the physical characteristics of the asteroid. NASA's Double Asteroid Redirection Test mission in September 2022 gave a team of scientists a unique opportunity -- to observe the evolution of an asteroid's ejecta as it happened.
Published DNA repair discovery could improve biotechnology
(via sciencedaily.com) A team of researchers has made a discovery that may have implications for therapeutic gene editing strategies, cancer diagnostics and therapies and other advancements in biotechnology.
