New research indicates that simple laser treatments to the skin may help to prevent the development of basal cell carcinoma and squamous cell carcinoma, which are collectively known as keratinocyte ...

Devices that convert the energy from footsteps, arm movements, and breathing into electricity could charge smart watches and wearables. But they are complicated and costly to make. Now a team has made ...

Modern technologies increasingly rely on light sources that can be reconfigured on demand. Think of microlasers that can quickly switch between different operating states—much like a car shifting ...

In a study of patients with a history of facial keratinocyte carcinoma, 20.9% of those treated with nonablative fractional lasers experienced a subsequent keratinocyte carcinoma, compared with 40.4% ...
