Apple Has Lost Control of the iPhone. This New Game Emulator Is Proof.
— Lais Borges/Inverse; Photograph by Ian Carlos CampbellGame emulation is having a big moment on the iPhone. Earlier this month, in a surprise move, Apple updated its app review guidelines to allow for retro game emulators on the App Store, a change that the company has resisted since the original iPhone launched in 2007. Game emulators aren’t illegal, but Apple has long been afraid of inadvertently supporting piracy (and losing out on the potential for game purchases in its own store).Since A
New metasurface innovation unlocks precision control in wireless signals
<div>Researchers have unveiled a technology that propels the field of wireless communication forward. This cutting-edge design, termed a reconfigurable transmissive metasurface, utilizes a synergistic blend of scissor and rotation actuators to independently manage beam scanning and polarization conversion. This introduces an innovative approach to boosting signal strength and efficiency within wireless networks.</div>
