A neutron star’s weird wind rewrites space physics12:07 XRISM’s observations of GX13+1 revealed a slow, fog-like wind instead of the expected high-speed blast, challenging existing models of radiation-driven outflows. The discovery hints that temperature differences in accretion discs may determine how energy shapes the cosmos. A hidden breathing problem may be behind chronic fatigue’s crushing exhaustion12:07 Scientists have discovered that most chronic fatigue patients experience dysfunctional breathing, which may worsen their symptoms. The likely culprit is dysautonomia, a disruption in how the body controls blood vessels and muscles. Breathing retraining, yoga, or biofeedback could help restore proper breathing rhythm and ease fatigue. The findings open a promising new path for managing this long-m… Physicists prove the Universe isn’t a simulation after all9:52 New research from UBC Okanagan mathematically demonstrates that the universe cannot be simulated. Using Gödel’s incompleteness theorem, scientists found that reality requires “non-algorithmic understanding,” something no computation can replicate. This discovery challenges the simulation hypothesis and reveals that the universe’s foundations exist beyond any algorithmic system. AI unravels the hidden communication of gut microbes9:52 Scientists have turned to advanced AI to decode the intricate ecosystem of gut bacteria and their chemical signals. Using a Bayesian neural network called VBayesMM, researchers can now identify genuine biological links rather than random correlations. The system has already outperformed traditional models in studies of obesity, sleep disorders, and cancer. Supercomputer breakthrough exposes Enceladus’s hidden ocean9:52 From Cassini’s awe-inspiring flybys to cutting-edge simulations, scientists are decoding the secrets of Enceladus’s geysers. Supercomputer models show the icy moon’s plumes lose less mass than expected, refining our understanding of its mysterious interior. These discoveries could shape future missions that may one day explore its subsurface ocean—and perhaps even detect life below the ice. New bacterial therapy destroys cancer without the immune system5:29 A Japanese-led research team has developed AUN, a groundbreaking immune-independent bacterial cancer therapy that uses two harmonized bacteria to destroy tumors even in patients with weakened immune systems. By leveraging the natural synergy between Proteus mirabilis and Rhodopseudomonas palustris, AUN selectively targets cancer cells, reshapes itself within tumors, and avoids harmful side effect… New online tool can predict how well blood pressure drugs will work5:29 A new blood pressure calculator built on extensive clinical trial data helps doctors accurately estimate how much each medication will reduce blood pressure. The tool simplifies complex treatment choices and replaces unreliable BP measurements with solid evidence. Doctors found a way to stop a deadly metformin reaction5:29 A hospital in Thailand created a quick-action dialysis protocol for patients with metformin-associated lactic acidosis, a dangerous reaction to a common diabetes drug. The program sharply reduced deaths and sped up treatment times. Awareness also soared, showing how organized emergency pathways can transform patient outcomes. Microbes that breathe rust could help save Earth’s oceans17:48 Researchers from the University of Vienna discovered MISO bacteria that use iron minerals to oxidize toxic sulfide, creating energy and producing sulfate. This biological process reshapes how scientists understand global sulfur and iron cycles. By outpacing chemical reactions, these microbes could help stop the spread of oceanic dead zones and maintain ecological balance. A simple DNA test could reveal the right antidepressant for you17:48 Millions struggle with depression and anxiety, often enduring long waits for effective treatment. Scientists in Sweden, Denmark, and Germany are developing a genetic test to predict which medications will actually work. Using polygenic risk scores, they can analyze DNA variations linked to mental health and drug response. Astronomers shocked by mysterious gas found in deep space17:48 Astronomers have discovered phosphine gas in the atmosphere of an ancient brown dwarf, Wolf 1130C, using the James Webb Space Telescope. The finding is puzzling because phosphine, a potential biosignature, has been missing from other similar objects. The detection may reveal how phosphorus behaves in low-metal environments or how stellar remnants like white dwarfs enrich their surroundings with t… Dark energy might be changing and so is the Universe17:48 New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest evidence yet for an evolving cosmic force. Warm ocean beneath Saturn’s icy moon Enceladus may be perfect for life9.listopadu NASA’s Cassini mission has revealed surprising heat flow at Enceladus’ north pole, showing the moon releases energy from both ends. This balance of heat could allow its subsurface ocean to remain liquid for billions of years, supporting conditions for life. The study also refined estimates of ice thickness, giving scientists a clearer picture of where to search next. Meet the desert survivor that grows faster the hotter it gets9.listopadu In Death Valley’s relentless heat, Tidestromia oblongifolia doesn’t just survive—it thrives. Michigan State University scientists discovered that the plant can quickly adjust its photosynthetic machinery to endure extreme temperatures that would halt most species. Its cells reorganize, its genes switch on protective functions, and it even reshapes its chloroplasts to keep producing energy. The fi… 9,000-year-old ice melt shows how fast Antarctica can fall apart9.listopadu Around 9,000 years ago, East Antarctica went through a dramatic meltdown that was anything but isolated. Scientists have discovered that warm deep ocean water surged beneath the region’s floating ice shelves, causing them to collapse and unleashing a domino effect of ice loss across the continent. This process created a “cascading positive feedback,” where melting in one area sped up melting else… |
