A light-therapy machine called ReGen, produced by Energist, in Swansea, Wales, uses high-intensity LEDs, which the company claims will soften skin, smooth wrinkles, and erase blemishes. Each of the four light boxes has a 255- by 70-millimeter panel containing 1024 LEDs. At wavelengths of 415 nanometers, they glow blue; when they’re set at 630 nm, they’re red. A third mode—which produces purple light by mixing blue and red—is claimed to combine the benefits of both treatments. Twenty minutes twice a week is supposed to reduce the signs of aging.

Are You Ready for Workplace Brain Scanning?

Extracting and using brain data will make workers happier and more productive, backers say

Get ready: Neurotechnology is coming to the workplace. Neural sensors are now reliable and affordable enough to support commercial pilot projects that extract productivity-enhancing data from workers’ brains. These projects aren’t confined to specialized workplaces; they’re also happening in offices, factories, farms, and airports. The companies and people behind these neurotech devices are certain that they will improve our lives. But there are serious questions about whether work should be organized around certain functions of the brain, rather than the person as a whole.

To be clear, the kind of neurotech that’s currently available is nowhere close to reading minds. Sensors detect electrical activity across different areas of the brain, and the patterns in that activity can be broadly correlated with different feelings or physiological responses, such as stress, focus, or a reaction to external stimuli. These data can be exploited to make workers more efficient—and, proponents of the technology say, to make them happier. Two of the most interesting innovators in this field are the Israel-based startup InnerEye, which aims to give workers superhuman abilities, and Emotiv, a Silicon Valley neurotech company that’s bringing a brain-tracking wearable to office workers, including those working remotely.
