The UK-made Ratio Mech is a modular, all-purpose 1x mechanical rear derailleur designed to replace existing derailleurs across various bike types, promising improved shifting through reduced friction without electronic components. It features a versatile design compatible with different mounting styles and gear ranges, and is user-serviceable and rebuildable.
A new study published in Nature Climate Change reveals that the Gulf Stream, a powerful ocean current that influences weather patterns and carries heat from the tropics to higher latitudes, has been warming faster than the global ocean and shifting closer to the coast over the past two decades. The study, based on extensive temperature and salinity profiles collected between 2001 and 2023, shows that the near-surface layer of the Gulf Stream has warmed by about 1°C and moved about 5 kilometers closer to the Northeastern United States continental shelf. The findings provide observational confirmation of predictions made by numerical simulations and highlight the potential impact on coastal fisheries and weather patterns.
The war on drugs is witnessing a shift in tactics, according to experts.

The article discusses the changing strategies in the fight against drugs, highlighting the need for new approaches and perspectives to address the issue effectively.
MLB has introduced several rule changes this season, including a pitch clock, shift restrictions, and larger bases. The rules for shifting require two infielders on each side of second base, but the third baseman and shortstop can switch positions mid-inning. Pitch-timer violations are not reviewable by replay, and MLB seems committed to the current version of the pitch clock. Teams risk a lot by playing a two-man outfield, but if it becomes more pervasive, MLB has the right to change the rule. The distance between the bases has never been 90 feet, and the new bases will shorten the distance between first and second base by 4 1/2 inches. Umpires have discretionary powers, and there is definitely such a thing as umpire discretion.
