Published Chemists create organic molecules in a rainbow of colors
(via sciencedaily.com) Original source Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.
Published From infamy to ingenuity: Bacterial hijack mechanisms as advanced genetic tools
(via sciencedaily.com) Original source Researchers have uncovered the intricate molecular mechanism used by parasitic phytoplasma bacteria, known for inducing 'zombie-like' effects in plants.
Published Unlocking neutron star rotation anomalies: Insights from quantum simulation
(via sciencedaily.com) Original source A collaboration between quantum physicists and astrophysicists has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic cosmic phenomenon with ultracold dipolar atoms. This research establishes a strong link between quantum mechanics and astrophysics and paves the way for quantum simulation of stellar objects from Earth.
Published Astronomers determine the age of three mysterious baby stars at the heart of the Milky Way
(via sciencedaily.com) Original source Through analysis of high-resolution data from a ten-meter telescope in Hawaii, researchers have succeeded in generating new knowledge about three stars at the very heart of the Milky Way. The stars proved to be unusually young with a puzzling chemical composition that surprised the researchers.
Published Can signs of life be detected from Saturn's frigid moon?
(via sciencedaily.com) Original source Researchers have shown unambiguous laboratory evidence that amino acids transported in the ice plumes of Saturn's moon, Eceladus, can survive impact speeds of up to 4.2 km/s, supporting their detection during sampling by spacecraft.
Published Interpreting the afterglow of a black hole's breakfast
(via sciencedaily.com) Original source An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of astronomers.
Published 10-billion-year, 50,000-light-year journey to black hole
(via sciencedaily.com) Original source A star near the supermassive black hole at the center of the Milky Way Galaxy originated outside of the Galaxy according to a new study. This is the first time a star of extragalactic origin has been found in the vicinity of the super massive black hole.
Published Dark galactic region nicknamed 'The Brick' explained with Webb telescope findings
(via sciencedaily.com) Original source Using the James Webb Space Telescope, astronomers spot unexpected source of carbon monoxide ice at galactic region surprisingly devoid of stars.
Published Researchers decode aqueous amino acid's potential for direct air capture of CO2
(via sciencedaily.com) Original source Scientists have made a significant stride toward understanding a viable process for direct air capture, or DAC, of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions, where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.
Published New technique efficiently offers insight into gene regulation
(via sciencedaily.com) Original source Researchers have developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease. MAbID offers new insights into how these mechanisms work together or against each other.
Published Ghostlike dusty galaxy reappears in James Webb Space Telescope image
(via sciencedaily.com) Original source Astronomers studying images from the James Webb Space Telescope have identified an object as a 'dusty star-forming galaxy' from nearly 1 billion years after the Big Bang. They have also discovered more than a dozen additional candidates, suggesting these galaxies might be three to 10 times as common as expected. If that conclusion is confirmed, it suggests the early universe was much dustier than previously thought.
Published Meteorites likely source of nitrogen for early Earth
(via sciencedaily.com) Original source Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system.
Published PicoRuler: Molecular rulers for high-resolution microscopy
(via sciencedaily.com) Original source A team presents a groundbreaking advance for the world of high-resolution fluorescence microscopy: The innovative method enables researchers for the first time to use biomolecules as molecular rulers to calibrate the latest super-resolution microscopy methods, which have a resolution of just a few nanometers.
Published Discovery of planet too big for its sun throws off solar system formation models
(via sciencedaily.com) Original source The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems.
Published Researchers reveal new process for making anhydride chemical compounds
(via sciencedaily.com) Original source A collaborative research team has discovered a new process for making anhydrides that promises improvements in costs and sustainability.
Published Rocky planets can form in extreme environments
(via sciencedaily.com) Original source Astronomers have provided the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy. These results suggest that the conditions for terrestrial planet formation can occur in a possible broader range of environments than previously thought.
Published An astronomical waltz reveals a sextuplet of planets
(via sciencedaily.com) Original source Astronomers have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm. This rare property enabled the team to determine the planetary orbits which initially appeared as an unsolvable riddle.
Published Artificial intelligence paves way for new medicines
(via sciencedaily.com) Original source Researchers have developed an AI model that can predict where a drug molecule can be chemically altered.
Published Releasing brakes on biocatalysis
(via sciencedaily.com) Original source Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase.
Published Building blocks for life could have formed near new stars and planets
(via sciencedaily.com) Original source While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices. The findings could be used to train deep space instruments like the James Webb Space Telescope to search for prebiotic molecules in distant, star-forming regions of the universe.
