Scientists trace 1840s train disruption to geomagnetic storm, fix historical typo

By filing add-on patents for minor modifications or new formulations, companies can delay generic competitors from entering the market. This tactic allows drugmakers to maintain high prices for longer periods, limiting affordable alternatives for consumers. The trend has drawn scrutiny from researchers and policymakers concerned about its impact on drug affordability.

This marks the second rollback under Trump, who previously cut the standard to 40 mpg during his first term in 2020. The latest reduction further loosens the fuel efficiency targets that automakers must meet across their vehicle fleets. Critics argue the move will increase fuel consumption and emissions, while supporters contend it eases regulatory burdens on the automotive industry.

Bose QuietComfort Ultra Gen 2 gains Auracast support via firmware update

Bose has released a firmware update for its $449 QuietComfort Ultra Headphones Gen 2, adding Bluetooth LE Audio and Auracast as beta features. This makes the flagship model the first Bose headphone to support Auracast, a technology that enables shared wireless audio broadcasts and improves accessibility. The company has indicated plans to extend the feature to more of its devices in the future. Auracast adoption remains limited in the industry, with only a handful of brands — including Sony, JBL, Samsung, and Sennheiser — currently supporting it on select products.
