Clams, oyster and more: ISS astronauts ditch Apollo-era Thanksgiving; enjoy special holiday meal

Microsleep is a brief, involuntary shutdown of the brain lasting 1–30 seconds, often arriving with tiny dream-like flashes and no warning. Anaesthesiologist Dr Myro Figura describes it as the brain “blacking out” after severe sleep deprivation, a danger linked to thousands of road crashes. Sleep clinics warn that inconsistent sleep, long wakeful hours and late-night driving make these episodes far more likely.

Short-form video wasn’t supposed to become our generation’s Matrix, yet here we are, scrolling ourselves into a new cognitive baseline. Drawing on Feeds, Feelings and Focus, a meta-analysis of 71 studies and nearly 100,000 people, this piece maps how TikTok, Reels and Shorts quietly retrain the mind. Attention thins, emotions accelerate, adults prove no more resilient than teenagers, autonomy erodes in micro-increments, and identity becomes whatever narrative the algorithm reflects b

ESA's Juice spacecraft has captured striking new images of Comet 3I/ATLAS, revealing its active coma and distinct plasma and dust tails. While originally designed for Jupiter, Juice's navigation camera provided an early glimpse of the comet's activity. Full scientific data, gathered by five specialized instruments, is expected in February 2026, promising deeper insights into this interstellar visitor.

New research reveals ancient humans in southern Africa lived in isolation for nearly 100,000 years. This led to unique genetic traits not seen in modern populations. These findings show human evolution was complex, involving multiple isolated groups. The study analyzed genomes from 28 ancient individuals, offering insights into early human diversity and adaptation.

Scientists at the University of British Columbia Okanagan say they’ve found a mathematical limit that shuts down the Simulation Hypothesis entirely. Drawing on Gödel’s incompleteness theorem, their study argues that parts of reality cannot be generated by any algorithm, which means no computer, however advanced, could ever build a universe like ours. The obstacle isn’t processing power. It’s logic itself.

A powerful 2025 Kuril-Kamchatka earthquake generated a Pacific-wide tsunami, captured by NASA's SWOT satellite.These unprecedented high-resolution images reveal complex, braided wave patterns, challenging the assumption that large tsunamis travel as non-dispersive waves.This discovery offers crucial new insights into mid-ocean energy distribution, promising to significantly improve future tsunami forecasting and hazard assessments.

Bennu asteroid samples returned by NASA's OSIRIS-REx mission reveal life's building blocks, including sugars like ribose and glucose. Scientists also found a unique nitrogen-rich polymer, offering clues to early life's chemical origins. The asteroid's high concentration of supernova dust sheds light on its formation environment and the distribution of presolar materials in our early solar system.

India and Russia are poised to significantly boost space collaboration, with Roscosmos hinting at a major announcement soon.Discussions are reportedly covering engine development, crewed missions, and orbital stations, emphasising mutual benefit over technology transfer. President Putin's visit aims to elevate ties across various sectors, including energy and industry, to a new qualitative level.

Bengaluru-based Biomoneta has achieved a significant first, becoming the inaugural Indian healthtech firm to secure US-FDA 510(k) Class II clearance for its innovative medical air-cleaning device. This breakthrough, powered by their unique ZeBox technology, promises to revolutionize hospital infection control by effectively eliminating airborne pathogens, including SARS-CoV-2, paving the way for its deployment in US healthcare facilities.

New research has confirmed that a vast ring of Neolithic pits, more than a mile wide and over 4,000 years old, was deliberately engineered near Stonehenge, not formed by nature. Using cutting-edge dating and soil-analysis techniques, researchers argue it reflects an ancient belief system inscribed into the land itself. The discovery suggests Stonehenge’s builders shaped not only monuments of stone, but also monuments of earth.
