Scientists add bacteria to a waste gas reactor what happened next is nearly impossible
Norwegian scientists have engineered a process using specialized bacteria to convert industrial waste gases, carbon dioxide and hydrogen, into nearly pure methane. This biologically produced fuel, exceeding 96% purity, can be used in existing natural gas systems, offering a sustainable solution for storing renewable energy and replacing fossil fuels.
Interstellar comet 3I/ATLAS, a 7.5-billion-year-old visitor from the early galaxy, is offering scientists a rare glimpse into the universe's past. Professor Brian Cox marvels at humanity's progress, noting we now photograph such ancient objects from other planets, a stark contrast to just centuries ago when Earth's place in the cosmos was debated. Its unique composition and trajectory provide invaluable insights.
2 green comets shine bright. How to spot them in the night sky?
Two bright green comets, Comet Lemmon and Comet SWAN, are currently visible in the Northern Hemisphere after originating from the outer solar system. Comet Lemmon will have its closest approach to Earth around Tuesday, while Comet SWAN's flyby occurred Monday and it is now dimming. Spotting both simultaneously without special equipment is a rare but notable celestial event.
The hidden planet beyond Pluto: Is Planet Y real
Astronomers are investigating a potential hidden planet, dubbed Planet Y, far beyond Neptune. Its gravitational pull is suspected to be causing unusual orbital tilts in distant Kuiper Belt Objects. This elusive world, estimated to be smaller than Earth but larger than Mercury, could revolutionize our understanding of the Solar System's formation and structure.
Aliens got bored: NASA scientist gives bizarre reason why aliens have stopped contacting us
A NASA astrophysicist proposes 'radical mundanity,' suggesting aliens haven't contacted us because they're not vastly superior, just slightly ahead. After exploring, they may have lost interest in making contact, finding Earth unremarkable. This theory offers a grounded explanation for the Fermi paradox, suggesting modest civilizations limited by physics and motivation.
4.5-billion-year-old traces of proto-Earth discovered could rewrite our planets origin story
MIT scientists have discovered ancient rock samples from Greenland, Canada, and Hawaii exhibiting a rare potassium-40 deficit. This chemical signature suggests these rocks are remnants of proto-Earth, predating the giant impact that formed the Moon. The findings challenge previous assumptions about the early Earth's complete remelting and offer a glimpse into the solar system's initial chemistry.
The International Space Station is set for a controlled deorbit by 2030. This orbiting laboratory, a testament to global collaboration, has hosted thousands of experiments, significantly advancing science and technology. NASA is now transitioning to privately operated space stations to maintain human presence in orbit, fostering a new era of space exploration.
Google for DNA: Scientists create the worlds first and fastest genetic search engine
Scientists at ETH Zurich have unveiled MetaGraph, a revolutionary tool dubbed 'Google for DNA'. This innovation allows rapid searches across vast genetic databases, overcoming the slow, resource-intensive methods previously used. MetaGraph's compressed index promises to accelerate research into diseases, antibiotic resistance, and rare genetic conditions, making genetic exploration faster and more comprehensive.
SpaceX's Starship rocket completed a significant test flight, traveling halfway around the globe and deploying mock satellites before landing in the Indian Ocean. This eleventh mission, crucial for NASA's lunar landing goals by 2030, saw the massive rocket successfully separate its booster and test entry procedures over the ocean.
Isro opens XPoSat observatory to Indian scientists
India's XPoSat mission is now open for proposals from Indian scientists. Launched in January 2024, this X-ray observatory offers a chance to study extreme cosmic phenomena. Sixty percent of observation time for the XSPECT payload is reserved for Indian researchers from January to December 2026. Submissions are due by November 30, 2025.
Mount Everest has captivated the world with recent stunning views from both space and the Indian plains. Astronaut Don Pettit shared a striking ISS photograph of the Himalayas, while a rare video from Bihar showed the mountain visible from the plains due to exceptional atmospheric clarity. These visuals highlight Everest's enduring allure and the grandeur of the Himalayas.
The real cause of depression may lie in just two brain cell types, scientists say
Scientists have pinpointed specific neurons and microglia, crucial for emotion and inflammation, as key players in depression. This breakthrough, using advanced brain tissue analysis, reveals disrupted gene activity in these cells. The findings offer a biological foundation for the disorder, paving the way for more targeted and effective future treatments for millions worldwide.
