How big the predicted deviations are: from ~10⁻²³ m for a falling 87Rb atom on Earth to percent-level effects near a mini black hole with Schwarzschild radius ~1 mm. What makes TU Wien’s approach different from other quantum gravity ideas, and how it connects quantum mechanics explained in standard textbooks with curved spacetime. How future high-precision experiments and extreme-gravity environments could test whether particles truly follow Einstein’s paths or quantum-corrected q-desics.

NASA DART mission uncovers ‘cosmic snowballs in space’ around asteroid moon Dimorphos and the Didymos asteroid system. This episode explains how an asteroid impact mission revealed near-Earth asteroids quietly trading material across space rocks and asteroids. Learn how NASA space discoveries are rewriting asteroid science, from fast-spinning primaries to debris-sharing asteroid moon systems. What You'll Learn: How the NASA DART mission was designed as an asteroid impact mission and why Dimorphos was chosen as the target in the Didymos asteroid system. What the DRACO camera saw in its final images and how a 0.6 m per pixel resolution at 1,000 km revealed faint streaks interpreted as “cosmic snowballs in space.” Why Didymos spinning once every 2.26 hours puts it near the theoretical breakup limit and what that means for rubble-pile asteroids. How sunlight can spin up near-Earth asteroids (the YORP effect) until they shed debris that can drift toward nearby asteroid moons. The orbital relationship between Didymos and Dimorphos—an 11.9-hour orbit at roughly 1.2 km distance—and how that close pairing enables material exchange. Why these “cosmic snowballs” are the first direct visual proof that active processes constantly reshape near-Earth asteroids. What this discovery means for future planetary defense missions and how understanding asteroid moon systems improves impact risk assessments. How NASA space discoveries like DART help scientists better predict the structure, evolution, and behavior of space rocks and asteroids.

Chronic constipation and gut bacteria: new constipation disease finally explained Breakthrough discovery of “bacterial constipation” links specific gut bacteria to dry stool, intestinal mucus gut health, and treatment-resistant constipation. Understand how Akkermansia muciniphila and Bacteroides thetaiotaomicron may be driving your chronic constipation—and what this means for future diagnosis and treatment. What You'll Learn: How chronic constipation can be driven by specific gut bacteria, not just diet, fluids, or motility issues. Why Akkermansia muciniphila and Bacteroides thetaiotaomicron are implicated in a new form of “bacterial constipation.” What intestinal mucus does for gut health, lubrication, and stool hydration—and what happens when it’s stripped away. How co-colonised mice developed a 2.7-fold higher colonic transit time compared to germ-free controls, and why that matters for humans. What the human data show: 71% of refractory-constipation patients carried high levels of both bacteria vs only 9% of healthy controls. Why standard constipation treatments (fiber, laxatives, stool softeners) often fail when the underlying problem is mucus-destroying bacteria. How this research could change future testing, diagnosis, and targeted therapies for chronic constipation and dry stool causes. Practical questions to ask your doctor about gut microbiome and digestion if you have treatment-resistant constipation.

Arctic snow loss and satellite climate data: how a decades-long measurement illusion hid the true decline in Northern Hemisphere snow cover. This climate change podcast episode unpacks why satellite climate data once showed growing autumn snow, and how new analysis reveals rapid Arctic snow loss instead. Understand what this means for global warming science, Arctic warming, and the future of our planet. What You'll Learn: • How a spurious satellite trend turned an apparent October snow cover increase (+0.3 million km²/decade) into a robust decline once corrected. • Why updated estimates now show a −0.45 to −0.55 million km²/decade loss of Arctic October snow extent north of 60° N between 1982 and 2020. • How improvements in satellite imagery analysis and snow detection created a misleading long‑term climate signal. • What “snow extent,” “snow cover,” and “surface albedo” really mean in the context of global warming science. • How Arctic snow cover decline interacts with albedo feedback to amplify regional warming (and why each 10 % loss matters, with caveats). • How climate scientists validate, correct, and reconcile satellite climate data records over multiple decades. • What shrinking Northern Hemisphere snow cover implies for future climate projections, ecosystems, and human communities.
