FEATURES
Lasers Help Carmakers Chase Fuel Efficiency Laser-based technologies and techniques including drilling, welding and measurement allow auto manufacturers to keep pace with the demand for lower emissions. For car manufacturers, the number 54.5 looms large. That’s the mile-per-gallon requirement from the U.S. Environmental Protection Agency set to take effect in 2025. That figure represents roughly a 70 percent increase over the 2014...
Vehicle Vision Puts the 'Auto' in 'Automobile' Vision systems are increasingly enabling self-driving cars to automatically park, maintain speed and prevent collisions. Can a world of ubiquitous self-driving cars be far off? Whether it’s a...

EDITORIAL
And We’ll Have Fun, Fun, Fun ’Til the 409 Drives Itself The distinctive sound of The Beach Boys has been ringing in my ears since a recent concert I attended. Songs about cars and driving have long been among my favorites, probably because I’ve always enjoyed driving. I especially like my current winding and hilly route to work. I wonder, though, what it would be like in a self-driving car: I could enjoy the passing scene without a care, and it...
TECH PULSE
Metamaterial Shows Promise as THz Imager An imaging approach involving metamaterials could make the terahertz regime more accessible. Researchers from Boston College, the University of New Mexico and Duke University engineered a low-power multiplex tunable spatial light modulator (SLM) that uses a series of masks to retrieve multiple samples, which are reassembled by a single-pixel detector. Data obtained from these encoded measurements...

TECHNOLOGY NEWS
Swelling Sensor Detects Toxic Gas Those who work with hazardous substances could find an extra measure of protection in an optical sensor that puffs up in the presence of even trace amounts of toxic gases. Made from a 400-nm-thick film of polymethyl methacrylate (PMMA), the sensors are infused with fluorescent dye and patterned with 1-D photonic crystal cavities suspended in air. Certain gases cause the PMMA to swell, changing...

Tofu Chemical Could Prompt New Wave of Solar Cells Solar cells could learn a thing or two from tofu and bath salts. Researchers from the Stephenson Institute for Renewable Energy at the University of Liverpool in England have found that magnesium chloride (MgCl2) – found in tofu, bath salts and de-icing solutions – may produce more cost-effective and efficient solar cells. The compound could serve as a replacement for cadmium chloride...
LIGHTER SIDE
Bees Are No Bumblers When flowers start to bloom, you know it. The smell of honeysuckle, lilacs or gardenias wafts through the air and into our noses as we walk outside, drive down the road or, with any luck, wake up next to an open window. The perfume is intoxicating, and it’s no surprise that bees and other insect pollinators are drawn to these fragrant blossoms. However, their journey has nothing to do with...
