Saturn’s moon Titan has shocked scientists by breaking a key chemistry rule. NASA and Chalmers University researchers found that polar and nonpolar molecules, usually immiscible, can mix under Titan’s extreme cold. The discovery deepens our understanding of prebiotic chemistry and could reveal how life’s building blocks form in frigid extraterrestrial environments.

A team of scientists has created a microscopic engine made from a 5-micrometre glass bead suspended in an electric field. By applying oscillating voltages, the bead moves as if it’s in an environment of 13 million°C, even though it remains cool. The study reveals bizarre thermodynamic effects at tiny scales, offering clues to how natural molecular “machines” work inside living cells.

A new “mechanochemical” process allows the recycling of Teflon by grinding it with sodium metal at room temperature. This solvent-free reaction breaks down Teflon’s carbon-fluorine bonds, producing harmless carbon and sodium fluoride instead of toxic PFAS. The sodium fluoride can be reused in fluorine-based products, making this approach a breakthrough for sustainable plastic recycling and circular fluorine chemistry.

Google is expanding its Gemini AI assistant to more Android devices, officially replacing Google Assistant. Users are being notified via email, which also outlines how their data is handled. Gemini offers conversational interactions, app integration, and live assistance via screen sharing and video calls. However, Google clarifies that chats and activity data may be reviewed for training, but can be turned off.

Oppo Reno 15 series' key specifications have surfaced online, hinting at what the lineup could offer. The lineup is expected to feature an Oppo Reno 15 and a Reno 15 Pro Max. The company could also unveil a model with a 6.59-inch display as the of the Reno 15 series. The Reno 15 Pro Max, which was earlier tipped to feature a Dimensity 9400 SoC, is now expected to be powered by a MediaTek Dimensity 8450 chipset.
