The three-body problem broke Newton, broke Poincaré (who ended up inventing chaos theory trying), and was finally cracked open by Chenciner & Montgomery in 2000: the figure-8 in clip 4 is their proof. Šuvakov & Dmitrašinović added 13 more families by 2013. Every clip is a real numerical integration of F = G·m₁m₂/r² with equal masses, no fudging. Math from 1687 still has surprises in it.

The Sun has only 22 galactic orbits left. Earth races around the Sun at ~67,000 mph (107,000 km/h), giving us our familiar 365.25-day year and changing seasons. But the Sun is in motion too—hurtling through the Milky Way at ~514,000 mph (828,000 km/h) on a grand orbit around the galactic center. One complete lap, known as a cosmic year, takes roughly 225–230 million years. When the Sun finished its most recent galactic orbit, the earliest dinosaurs were just beginning to roam Earth. Since its birth ~4.6 billion years ago, our star has completed about 20 such orbits. Stellar models predict the Sun will keep fusing hydrogen in its core for another ~5 billion years before it swells into a red giant and eventually fades into a white dwarf. At its current orbital speed, that leaves roughly 22 more laps around the Milky Way. Each cosmic year sweeps the entire Solar System tens of thousands of light-years across the galaxy—through dense spiral arms rich with star-forming regions, past ancient globular clusters, and amid countless other stars. Continents drift, mountains rise and erode, entire species evolve and vanish—all within a tiny fraction of one galactic circuit. Human civilization, from the first cities to today’s digital age, has existed for less than 0.001% of a single cosmic year. We are passengers on a star halfway through its ~10-billion-year galactic journey across a 100,000-light-year-wide disk—witnessing just the briefest sliver of one ongoing lap in an unimaginably vast cosmic dance.

Yes: handwriting still matters. A new study has confirmed that writing by hand activates far more complex and widespread neural networks in the brain than typing, underscoring its importance for learning and memory. Researchers at the Norwegian University of Science and Technology used a high-density EEG cap with 256 electrodes to record brain activity in university students. They found that the intricate, sensory-rich movements involved in handwriting, especially cursive, trigger highly synchronized brain waves across extensive areas of the parietal and central regions. These coordinated patterns are strongly linked to memory formation, cognitive processing, and encoding new information. In contrast, typing, which involves repetitive, simpler finger movements, produced significantly less neural connectivity and engagement. The difference was striking: the brain appears much less active during digital writing. The researchers conclude that the unique motor and sensory experience of holding a pen plays a key role in brain development and learning. As a result, they argue that handwriting instruction should remain a core part of education to support deeper comprehension and cognitive growth in the next generation.

China now officially hosts the world’s fastest supercomputer. The new system, named LineShine, has claimed the #1 spot on the TOP500 list with a staggering performance of 2.198 exaflops, making it the fastest publicly verified supercomputer on the planet. To put that in perspective: one exaflop equals one quintillion (1,000,000,000,000,000,000) calculations per second. LineShine can perform more than 2 quintillion calculations every second, meaning it can solve in a single day what would take a regular computer thousands or even millions of years. Unlike your laptop or phone, a supercomputer is not a single device, it’s a massive cluster of thousands of processors working in parallel. It breaks enormous problems into millions of smaller tasks, solves them simultaneously, and combines the results. These machines are essential for tackling humanity’s toughest challenges: simulating hurricanes, modeling climate change decades ahead, designing new materials at the atomic level, running nuclear simulations, accelerating drug discovery, and training powerful AI models. What makes LineShine particularly notable is that it achieved this record without using GPUs — the chips that power most modern AI systems. Instead, it relies entirely on traditional CPUs, showing an alternative route to exascale computing (machines exceeding 1 exaflop). Only a few publicly confirmed exascale supercomputers exist today. Of course, this level of performance comes with huge energy demands, LineShine consumes roughly 42.2 megawatts, enough electricity to power tens of thousands of homes. Even so, researchers are already looking ahead to the next milestone: zettascale computing — systems roughly 1,000 times more powerful than today’s exascale machines. If realized, they could revolutionize AI, climate modeling, medicine, and our understanding of the universe. Science and facts💡

A black fungus feeds on radiation in Chernobyl. In the radioactive ruins of Chernobyl’s Reactor 4, scientists found an extraordinary black fungus, Cladosporium sphaerospermum, thriving in one of Earth’s most toxic environments. Rather than merely enduring radiation, this fungus seems to harness it through radiosynthesis—a process akin to photosynthesis but driven by gamma radiation, converting it into chemical energy. It’s among the rare organisms capable of this feat. Even more remarkable, when tested on the International Space Station, the fungus flourished, forming a biofilm that blocked up to 84% of cosmic radiation, hinting at its potential as a living radiation shield for astronauts. With radiation posing a major hurdle for deep-space missions to Mars and beyond, this self-regenerating biological layer could revolutionize spacecraft design by replacing heavy, bulky shielding. On Earth, researchers are exploring its use in bioremediation to detoxify radioactive sites too hazardous for humans, potentially transforming nuclear disaster recovery. As one scientist put it, “It’s like nature crafted a biological radiation shield.” From Chernobyl’s ruins to space, this humble fungus could help humanity thrive in the universe’s harshest environments.

Creatine, long celebrated for supporting muscle growth and athletic performance, is gaining recognition in neuroscience as a powerful aid for brain energy management—especially under demanding conditions like mental stress, intense cognitive effort, or sleep deprivation. As the brain's primary energy currency, adenosine triphosphate (ATP) gets rapidly depleted during high-demand tasks. Creatine helps by facilitating the quick recycling of ATP through the phosphocreatine system, providing neurons with a more reliable energy buffer to sustain performance when demands spike. Recent systematic reviews and meta-analyses of randomized controlled trials have quantified these effects. A 2024 meta-analysis (Xu et al., Frontiers in Nutrition) found that creatine monohydrate supplementation significantly improved memory performance, with a standardized mean difference (SMD) of 0.31 (95% CI: 0.17–0.44; equivalent to Hedges' g ≈ 0.30), alongside benefits in information processing speed and attention time in some measures. An earlier 2023 meta-analysis (Prokopidis et al., Nutrition Reviews) reported an overall SMD of 0.29 for memory enhancement in healthy individuals, with particularly strong effects in older adults (SMD = 0.88 in those aged 66–76 years). While this 0.31 SMD reflects a modest-to-moderate standardized effect size (not a literal 31% raw improvement in every person or task), it indicates meaningful gains in memory, mental clarity, and processing efficiency—especially when the brain is challenged. Benefits tend to be most evident in specific groups: older adults (who may have lower baseline brain creatine), vegetarians/vegans (with naturally reduced dietary intake), females, and those experiencing sleep deprivation or high mental fatigue. Emerging research is also exploring creatine's therapeutic potential for neurological conditions such as Alzheimer's disease, traumatic brain injury, depression, and mild cognitive impairment, though evidence remains preliminary and strongest for memory support. Creatine isn't a miracle cure or standalone fix—it's best viewed as a supportive nutrient that bolsters brain resilience. Experts stress the need for more large-scale, long-term studies to clarify optimal dosing, duration, and broader impacts on neurological health. [Xu C, et al. (2024).

A new theoretical study proposes that time is not a universal constant throughout the universe, but an emergent phenomenon tied to the curvature of spacetime, one that could gradually weaken and eventually fade away as the cosmos expands. For decades, physicists have grappled with the idea that time may not be fundamental. Now, Anderson Gama Fernandes de Freitas of Brazil’s Federal University of Itajubá has introduced a “geometric clock” framework within general relativity. According to this model, time functions meaningfully only in regions where spacetime is sufficiently curved by gravity (such as near massive objects or in the dense early universe). In vast, nearly flat, empty regions of space, the geometric conditions supporting time break down, and it loses its operational meaning. As the universe continues to expand and becomes increasingly flat, this theory suggests that cosmic time itself may slowly “wind down,” eventually leading to a future where time ceases to exist in its current form. Beyond its striking implications for the fate of the universe, the model offers a promising approach to the long-standing “problem of time”, the fundamental incompatibility between quantum mechanics and general relativity regarding how time behaves. By treating time as a local, geometry-dependent feature rather than a universal backdrop, the framework helps bridge these two pillars of physics.
