@Shayne Coplan and his #prediction-market Polymarket crowdsource bets on real-world outcomes across 15 categories, and Coplan argues it is the most accurate thing we have. The platform hosts about 10,000 questions, lets users wager real money on yes/no outcomes, and odds shift as bets and news flow, with roughly $3.6 billion wagered on the Trump outcome. Coplan says Polymarket answers who is going to win rather than who voters will vote for, a signal that has at times diverged from polls, such as a 70%-30% projection for Trump early in October. Regulatory scrutiny, including investigations by the #CFTC and the #FBI, underscores tensions around prediction markets, even as the model remains a prominent example of crowd-based information in geopolitics and other sectors.
19. How Solar Flares Could Have Corrupted An Airbus Plane
Intense solar radiation could corrupt data critical to the A320’s flight controls, prompting Airbus to recall thousands of its aircraft for a software fix. The recalls followed an October incident involving an #A320 operated by @JetBlue that suddenly lost altitude and diverted to Tampa, with Airbus citing an elevator aileron computer #ELAC malfunction as a potential link to solar flares. An FAA directive notes the issue affected fleets worldwide, including more than 70% of Avianca’s planes, while some carriers such as @Delta and @United reported limited impact and American said all 209 affected aircraft were fixed. The proposed mechanism is that solar flares—massive bursts of electromagnetic radiation and large sunspot activity—could corrupt data to #flightcontrols, triggering unintended pitch changes and rapid descents. This episode underscores how space weather can pose real safety and logistics challenges for commercial aviation and aligns with warnings from @NOAA scientists about rising solar activity and potential geomagnetic disturbances associated with large sunspots.
20. Chernobyl Fungus Appears to Have Evolved an Incredible Ability
In the Chernobyl Exclusion Zone, a dark melanin-rich fungus, Cladosporium sphaerospermum, clings to the interior walls of one of the most radioactive buildings and appears to thrive in ionizing radiation. A late-1990s field survey led by @Nelli Zhdanova of the Ukrainian National Academy of Sciences documented 37 fungal species, with C. sphaerospermum dominating and showing some of the highest levels of radioactive contamination. Radiopharmacologist @Ekaterina Dadachova and immunologist @Arturo Casadevall led work showing that exposure to ionizing radiation does not harm this fungus and may even enhance its growth, and that ionizing radiation changes the behavior of fungal melanin. They proposed #radiosynthesis, a biological pathway in which melanin harvests radiation to generate energy much like #photosynthesis, while also shielding cells from damage. While radiosynthesis remains a theory that is difficult to prove, the findings point to a remarkable adaptive strategy for life in high-radiation environments, illustrating how C. sphaerospermum may exploit extreme conditions.
