Some iPhone 17 Pro Max units are experiencing a color shift from vibrant orange to rose gold due to aluminum oxidation, likely caused by sealing layer inconsistencies in certain production batches. Users are advised to inspect their devices, avoid abrasive cleaners, and contact Apple Support for potential replacements. The issue adds to other reported problems with the device, such as scratches and software bugs.

Tesla Cybertruck owners have reported seeing small orange specks of oxidation on their vehicles, which can be easily cleaned with solutions like Bar Keeper’s Friend. Tesla’s lead Cybertruck engineer, Wes Morrill, and CEO Elon Musk have affirmed that the stainless steel can be buffed to remove scratches and surface marks. Tesla Design Chief Franz von Holzhausen also discussed scratch removal on the Cybertruck, emphasizing the durability of the stainless steel finish. The company has developed a process for owners to buff out scratches and return the stainless steel to its original finish.

Green tea and black tea are both derived from the Camellia Sinensis plant, but they undergo different processing methods. Black tea is oxidized, resulting in a darker color and stronger, bitter flavor, while green tea remains unoxidized, giving it a milder taste with vegetal and floral notes. The caffeine content varies depending on factors such as tea type, preparation, and infusion time, but generally, green tea contains less caffeine than black tea.

Scientists have developed a catalyst with a hydrophobic cavity that contains an active iron centre to convert methane into methanol. The catalyst has a 'catch-and-release' mechanism where a hydrophobic methane molecule enters the cavity for oxidation and the resulting hydrophilic methanol molecule is released into the surrounding aqueous solution.
