Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»
Two European satellites launch on mission to blot out the Sun—for science
This will all happen nearly 40,000 miles above the Earth, so you won't need your eclipse glasses. Two spacecraft developed by the European Space Agency launched on top of an India.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Citizen scientist data help uncover the mysteries of a blue low-latitude aurora
Colorful auroras appeared around Japan's Honshu and Hokkaido islands on May 11, 2024, sparked by an intense magnetic storm. Usually, auroras observed at low latitudes appear red due to the emission of oxygen atoms. But on this day, a salmon pink auro.....»»
