Dark mode may not save your phone’s battery life as much as you think, but there are a few silver linings
When Android and Apple operating system updates started giving users the option to put their smartphones in dark mode, the feature showed potential for saving the battery life of newer phones with screens that allow darker-colored pixels to use less power than lighter-colored pixels.

WEST LAFAYETTE, Ind. – An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications.
The Purdue invention uses composite based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems. The interest in NLTLs has increased in the past few decades because they offer an effective solid-state alternative to conventional vacuum-based, high-power microwave generators that require large and expensive external systems, such as cryogenic electromagnets and high-voltage nanosecond pulse generators.

WEST LAFAYETTE, Ind. - An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications.
The Purdue invention uses composite based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems. The interest in NLTLs has increased in the past few decades because they offer an effective solid-state alternative to conventional vacuum-based, high-power microwave generators that require large and expensive external systems, such as cryogenic electromagnets and high-voltage nanosecond pulse generators.
NLTLs have proven effective for applications in the defense and biomedical fields. They create directed high-power microwaves that can be used to disrupt or destroy adversary electronic equipment at a distance. The same technology also can be used for biomedical devices for sterilization and noninvasive medical treatments.
