Space News ,World :- In the vast reaches of space, a peculiar green glow, reminiscent of a Grinch-like apparition, has been captivating astronomers. Known as the Green Monster, this enigmatic phenomenon was first spotted last year meandering through the remnants of a supernova, painting a mesmerizing scene in the cosmic canvas.Captured by NASA's James Webb Space Telescope alongside Hubble, Spitzer, and Chandra space telescopes, a recent image unveiled at the American Astronomical Society conference provides an unprecedented glimpse into the cosmic drama surrounding Cassiopeia A (Cas A). Situated approximately 11,000 light-years away, Cas A is an expanding shell of hot gas, and its light reached us 340 years ago.The captivating image showcases the Green Monster, a 10-light-year-long streak of light infused with red clouds, surrounded by cosmic hues of white, green, and orange. This celestial spectacle has ignited astronomers' curiosity, prompting a year-long quest to decipher its origin within the well-studied supernova remnant.The latest observations, combining the capabilities of multiple space telescopes, have propelled scientists closer to demystifying the Green Monster's origins. The image's X-ray properties align with the outer regions of the supernova debris field, suggesting that this peculiar feature emerged when a blast wave collided with material shed by the ill-fated star, tens of thousands of years before its explosive demise.Study co-author Ilse De Looze compares the Green Monster to a celestial photobomber, separate from the central part of Cas A. By digitally removing this cosmic intruder, astronomers gained unprecedented access to the background details, uncovering a well-preserved area near the explosion's epicenter.As the Green Monster took a backseat in the imagery, a "treasure map" unfolded, revealing a delicate, web-like network near the center of Cas A. Purdue University's Danny Milisavljevic, who led the study, expressed excitement at the opportunity to witness the "insides of a supernova explosion so well-preserved and with such detail."The network of "pristine debris" within Cas A likely formed during the star's collapse when its interior mixed with intensely hot radioactive matter. Milisavljevic emphasizes that studying these structures can provide valuable insights into the physical processes preceding a star's collapse.However, as one cosmic mystery unravels, another emerges. The Green Monster's greenish glow is adorned with "remarkably round holes," possibly formed when knots of supernova ejecta punctured an expanding cloud of stellar gas previously shed by the star.In the quest to unveil the nature of the ill-fated star and its activities leading up to the supernova explosion, future studies of the Green Monster and its mysterious circles hold the promise of shedding light on these cosmic enigmas.This groundbreaking research is detailed in a paper submitted to The Astrophysical Journal, marking a significant leap forward in our understanding of the celestial wonders that adorn our universe.

Space News ,NASA :- In a groundbreaking discovery using NASA's James Webb Space Telescope (JWST), astronomers have identified an unexpected phenomenon—a celestial aurora surrounding a brown dwarf known as W1935, located more than 40 light-years away from Earth. Brown dwarfs, often dubbed "failed stars," fall between gas giant planets and stars in size, forming from collapsing gas and dust clouds but lacking the mass required for hydrogen fusion.Unlike typical auroras witnessed on Earth or other planets, the mystery deepens around W1935 because no nearby stars exist to supply charged particles needed to generate the aurora. In the absence of an external solar wind, scientists speculate that internal processes within the brown dwarf or interstellar plasma may be responsible for the peculiar light display.The team, led by astronomer Jackie Faherty from the American Museum of Natural History, made this remarkable find while investigating a dozen brown dwarfs with JWST. Among them, W1935 stood out due to its methane emissions, detected through infrared signals—an unusual occurrence not observed in its near-identical counterpart, W2220.The researchers delved into modeling the atmospheres of these brown dwarfs to unravel the methane emission mystery. Surprisingly, they found that while W2220 exhibited a typical cooling with altitude, W1935 experienced a temperature inversion, heating up at higher altitudes—a puzzling phenomenon absent an apparent external heat source.Drawing parallels with Jupiter and Saturn, where similar temperature inversions are linked to auroras, the team theorizes that the aurora phenomenon might be responsible for W1935's atmospheric anomaly. This marks the first time that a methane emission from a brown dwarf has been associated with an aurora, according to JWST observations.Astronomer Ben Burningham of the University of Hertfordshire expressed astonishment at the unexpected temperature inversion, noting that similar instances were previously observed in planets with nearby stars, but not in celestial bodies lacking an obvious external heat source.Jackie Faherty, presenting the findings at the 243rd meeting of the American Astronomical Society in New Orleans, emphasized the significance of using the JWST to explore and understand celestial processes beyond our solar system. With W1935, scientists now have a unique opportunity to unravel the intricacies of auroral processes without the influence of stellar irradiation, providing a new perspective on the chemistry of brown dwarfs.

Technology News ,Medical science :- Scientists from MIT and Harvard have discovered a more effective way to correct genetic mistakes using tiny, virus-like particles. These particles, called engineered virus-like particles (eVLPs), carry prime editors into mouse cells with great success, fixing genetic disorders.Prime editing is a powerful technique for fixing genetic mutations that cause diseases. The researchers improved the editing process in human cells by 170 times by modifying these eVLPs. In tests on mice with genetic eye problems, they corrected mistakes and partially restored their vision.The breakthrough is seen as a promising treatment for genetic disorders in living animals. Importantly, when the same method was used to edit genes in the mouse brain, there were no unintended changes. This study marks the first time that therapeutic prime editing has been successfully delivered in an animal using protein-RNA complexes, according to David Liu, the senior author of the study.Scientists have been exploring gene editing to address genetic issues causing diseases. Prime editing, introduced in 2019, allows precise and diverse changes in DNA. However, delivering this editing system into living animal cells has been challenging.Different methods have been used, including lipid nanoparticles and viruses, with virus-like particles (VLPs) showing promise. VLPs are made of viral proteins and carry cargo but do not contain viral genetic material. Although VLPs have had some success, they require specific engineering for each cargo type.In their study, Liu and his team used their system to fix two different genetic problems in the eyes of mice. One issue causes a disease called retinitis pigmentosa, leading to gradual vision loss, and the other is linked to blindness in a condition called Leber congenital amaurosis (LCA) in humans.Using their eVLPs, they corrected the mutations in about 20 percent of the animals" retina cells, partially restoring their vision. The researchers made improvements to how the prime editing cargo was packaged, separated from the delivery vehicle, and entered the target cells" nuclei. These coordinated enhancements led to a 100-fold increase in efficiency, making the technique potentially suitable for therapeutic use in animals."This kind of improvement in efficiency should be enough to give us therapeutically relevant levels of prime editing," said Liu. "But we did not know for sure until we tested it in animals."

Space News ,Amazon :- In the race to revolutionize global internet connectivity, Amazon ambitious Project Kuiper has recently aced a critical milestone, setting the stage for a 2024 launch. Similar to SpaceX Starlink, Project Kuiper aims to usher in high-speed internet access by deploying 3,236 satellites in low Earth orbit (LEO).This endeavor saw two prototype satellites take to the skies in October, marking the initiation of comprehensive testing for the network operational systems. Among the pivotal assessments was the validation of the optical inter-satellite link (OISL) technology, utilizing infrared lasers for data transmission between spacecraft.The good news is, Amazon reports that the prototypes successfully navigated this crucial challenge. During testing, the two satellites maintained a robust connection speed of 100 gigabits per second.While OISL has traditionally facilitated connections between satellites situated farther from Earth, earlier iterations were limited to linking only two satellites. Amazon breakthrough extends beyond ensuring a high-speed link between the prototypes; it indicates the potential for the OISL to interconnect the entire constellation of 3,000-plus satellites, forming a sophisticated mesh network.Unlike conventional high-speed internet services powered by Earthbound optical fiber cables, Project Kuiper leverages space to transmit light, which travels 30% faster than its terrestrial counterpart, according to Amazon. With OISL, the project can efficiently route data throughout the network, enabling reception from any point on Earth and optimized routing based on network traffic.Maintaining OISL links between LEO satellites has historically been challenging due to the need for an extremely narrow beam over distances of up to 1,600 miles and between satellites hurtling at speeds of up to 15,000 mph. Amazon asserts that its advanced optics and control systems have successfully overcome these hurdles.Amazon ambitious timeline involves deploying enough satellites to commence customer pilots by mid-2024. Project Kuiper aims to provide speeds of up to 400 megabits per second for most users by 2029, approximately double the average U.S. broadband speed. Some organizations may even access speeds of up to 1,000 megabits per second, although the real-world and off-world feasibility of achieving such speeds when the system is fully operational remains uncertain. As the digital frontier continues to expand, Amazon Project Kuiper holds the promise of transforming global internet accessibility in the coming years.

Technology News ,Medical Science :- Scientists have found a brand-new kind of antibiotic that seems to be effective against one of the three bacteria that pose a major threat to human health due to their high drug resistance. This breakthrough involves a drug called Zosurabalpin, which successfully fought against Carbapenem-resistant Acinetobacter baumannii (Crab) in mouse models of pneumonia and sepsis. Crab is categorized as a top-priority pathogen by the World Health Organization, alongside two other drug-resistant bacteria.Dr. Andrew Edwards from Imperial College London, not involved in the study, emphasized the significance of this discovery. Crab causes infections in hospitals, especially in ventilator-dependent individuals. Its resistance to multiple antibiotics makes treatment challenging. Developing new treatments against Crab has been tough, but Zosurabalpin shows promise by overcoming the bacterium outer cell layer barrier.Antibiotic-resistant infections, especially those caused by Gram-negative bacteria, are a pressing threat to human health. Gram-negative bacteria have an outer shell with lipopolysaccharide (LPS), protecting them from antibiotics and immune system attacks. Roche Pharma Research and Early Development in Switzerland created Zosurabalpin, a drug identified for blocking A baumannii growth. Through experiments at Harvard University, researchers discovered that the drug prevents LPS transport, effectively killing the bacterium.While Zosurabalpin alone won"t completely solve the problem of antibiotic-resistant infections, it opens doors for future efforts targeting similar transport systems in other bacteria. Another antibiotic in development, murepavadin, also targets LPS transport but through a different mechanism, potentially expanding the approach to combat other antibiotic-resistant bacteria.Despite these advancements, transitioning from animal studies to human trials can be challenging. Simultaneously, the UK science, innovation, and technology committee advocate exploring bacteriophages, viruses that kill bacteria, as an alternative to antibiotics. However, the development of phage therapies faces obstacles, requiring specific standards for clinical trials, which, in turn, depend on successful clinical trials. The committee suggests considering the establishment of a facility in the West Midlands to support the production of bacteriophages.

These innovations are designed to make robots operate more efficiently, effectively, and safely. One notable improvement involves a data gathering system named AutoRT, which utilizes a visual language model (VLM) and a large language model (LLM) working together. This system enables robots to understand their surroundings, adapt to new settings, and determine suitable tasks.To ensure safety, DeepMind has implemented a "Robot Constitution," inspired by Isaac Asimov "Three Laws of Robotics." This set of safety-focused guidelines directs the LLM to avoid selecting tasks that involve humans, animals, sharp objects, and even electrical appliances. The robots are also equipped with a safety feature that automatically stops them if the force on their joints exceeds a certain threshold. Additionally, a physical kill switch is available for human operators to deactivate the robots, adding an extra layer of security.Over a seven-month period, Google deployed 53 AutoRT robots in four different office buildings, conducting over 77,000 trials. Some robots were controlled remotely by human operators, while others operated based on pre-programmed scripts or autonomously using Google Robotic Transformer (RT-2) AI learning model.In the trial, AutoRT VLM identified objects on a countertop, such as a sponge, cloth, a bag of chips, and a napkin. The LLM then suggested tasks like placing the napkin on the countertop and opening the bag of chips. AutoRT follows a systematic approach for each task, ensuring a logical and safe decision-making process.The robots used in the trial were practical in design, equipped with a camera, robot arm, and mobile base. DeepMind has also introduced two additional technologies. SARA-RT enhances the existing Robotic Transformer RT-2 with a more accurate and faster neural network architecture. RT-Trajectory incorporates 2D outlines to assist robots in performing specific physical tasks, such as wiping down a table.Although fully autonomous robots capable of serving drinks and fluffing pillows may still be in the distant future, these advancements pave the way for safer and more intelligent robotic systems, providing valuable lessons for future developments in the field.
