Editorial
The Cavalry Is Coming The doctor’s office has long served as the front line in the fight against disease and age-related ailments. Here, the undiagnosed threat is as dangerous as the undetected enemy. And in a scenario that would make most military generals queasy, the medical profession’s scouts — diagnostic technicians — commonly operate not in advance of the front, not at it, but behind it...

NIR-Activated Nanoparticle Therapy Suppresses Tumors A nanoparticle drug-delivery system that combines photodynamic and molecular therapies has been shown to suppress tumor progress and metastatic outgrowth in animal models. The complementary treatment could improve outcomes and mitigate toxicity for patients with pancreatic cancer and other treatment-resistant tumors. "A broad challenge in cancer treatment is that tumor cells use a network of...

Narrow Wavelength LED Light is New Rx for Picky Plants It does not take a brown thumb to know plants are fickle. But this winter many green-thumb gardeners growing fruits or perennials from seed — in a spare bedroom or whatever doubles as their greenhouse — will not realize just how picky their plants are. Even if the seeds sprout, leaves unfurl and buds flower, their fragrance may not reach its full potential. That’s because...
