The COP30 climate summit has commenced in Belém, Brazil, with UN Secretary-General António Guterres delivering a stark warning that failing to limit global warming to 1.5°C would be a "moral failure and deadly negligence." He emphasized that while a temporary overshoot of this critical target is now unavoidable, the severity of its impact hinges entirely on immediate and decisive global action to cut emissions and phase out fossil fuels.
A groundbreaking study published in Nature on November 5, 2025, has identified a distinct population of brain immune cells, known as microglia, that actively protect against Alzheimer's disease by reducing inflammation and slowing the accumulation of harmful amyloid plaques and tau proteins. This discovery, which pinpoints the PU.1-CD28 molecular pathway, offers promising new avenues for developing immunotherapy and novel treatments to potentially modify the course of Alzheimer's.
T-Mobile has dramatically expanded its satellite-powered "Text to 911" feature, making it freely available to all U.S. wireless users, regardless of their carrier, to provide a critical lifeline in remote areas. This groundbreaking initiative, leveraging Starlink's direct-to-cell satellites, covers approximately 500,000 square miles without traditional cell service and works automatically with compatible unlocked phones.
India's Parliamentary Affairs Minister Kiren Rijiju announced that the Winter session of Parliament is scheduled to convene from December 1 to December 19, 2025, a crucial period approved by President Droupadi Murmu to bolster democratic principles and address national aspirations.

Pop superstar Lady Gaga closely followed with seven nominations, and Bad Bunny made history as the first Spanish-language artist to be nominated in all three major categories.
Physicists are rigorously scrutinizing Albert Einstein's theory of relativity by employing black hole shadows to test its validity under the universe's most extreme gravitational conditions. This groundbreaking research, utilizing advanced simulations and anticipated ultra-sharp images from telescopes like the Event Horizon Telescope, aims to identify any deviations that could fundamentally re-evaluate our understanding of gravity and the universe.
North Korea's Defence Minister, No Kwang Chol, issued a stark warning on Saturday, November 8, 2025, threatening "more offensive action" after Pyongyang conducted a ballistic missile launch the previous day that traveled approximately 700 kilometers. This declaration comes amidst intensified criticism from Washington and Seoul, with North Korea accusing the United States of deliberately escalating regional tensions through recent sanctions and joint military exercises.
An Istanbul court has issued international arrest warrants for 37 Israeli officials, including Prime Minister Benjamin Netanyahu, on charges of crimes against humanity and genocide in Gaza. This significant legal action, citing incidents like hospital bombings and civilian deaths, marks a major escalation in Turkey's diplomatic efforts, though Israel has vehemently dismissed the warrants as a "PR stunt.
NYU researchers have unveiled "gyromorphs," a groundbreaking new class of materials poised to revolutionize light-based computing by efficiently rerouting microscopic light signals. These innovative materials uniquely combine properties of liquids and crystals, acting as "isotropic bandgap materials" to overcome limitations in traditional computing and pave the way for faster, more energy-efficient photon-based systems.
