Geochemists at Canadian universities measured and mapped naturally occurring hydrogen gas building up within billion-year-old rocks of the Canadian Shield, finding that boreholes at a mine near Timmins, Ontario release approximately 140 metric tons of hydrogen per year — enough to support the annual energy needs of over 400 households.^[1]

Paleontologists in Spain uncovered the best-preserved stegosaur skull ever found in Europe, a 150-million-year-old Dacentrurus armatus specimen that has led researchers to propose a new evolutionary group called Neostegosauria and redefine the relationships of stegosaurs worldwide.^[2]

Brazil coach Carlo Ancelotti named 34-year-old Neymar to the national team's 26-man World Cup squad, marking the forward's return to international competition after a near three-year absence following an ACL injury, with Brazil set to open their campaign against Morocco on June 13.^[3]

A large European study published in Annals of Internal Medicine found that a Mediterranean diet combined with calorie reduction, physical activity, and professional weight loss support reduced the risk of type 2 diabetes by 31%, with the PREDIMED-Plus study following nearly 5,000 participants.^[4]

Antarctica's Hektoria Glacier collapsed at a record pace, retreating 15 miles in just 15 months and setting a modern record for grounded ice loss, with scientists warning that similar processes affecting larger glaciers could accelerate sea level rise.^[5]

Japanese researchers traced a powerful medieval solar storm from around 1200 CE by linking ancient diary accounts of red lights in the sky over Kyoto with spikes of carbon-14 found in buried tree rings, revealing the Sun was far more active than previously understood during that period.^[6]

A major new review published in The Lancet Diabetes & Endocrinology found little convincing evidence that 'yo-yo dieting' causes long-term metabolic harm, challenging the widespread belief that repeated weight cycling is worse than staying overweight.^[7]

SpaceX's Starship V3 megarocket, the first of the new V3 design featuring larger grid fins and other upgrades, is now scheduled to launch on Thursday, May 21, at 6:30 p.m. EDT from Starbase, Texas, marking the first Starship test flight of 2026.^[8]

Researchers at Queen Mary University of London proposed that the universe's fundamental physical constants sit within an extremely narrow range that allows liquids to flow properly inside living cells, suggesting that life depends on a delicate cosmic balance.^[9]

New thermal evolution models suggest that Jupiter's moon Ganymede generates its unique magnetic field through ongoing core formation rather than convection in an already-formed core, offering new insights into how moons in the solar system evolve.^[10]
