Light in Darkness: Disabled Lives?

Photodynamic therapy: a light in the darkness?

Photodynamic therapy (PDT) is used to treat localized premalignant or early malignant disease. This study reports the enhanced, systemic antitumor immune response from PDT, suggesting that it may have a potential role as a therapy to address both local and disseminated disease.

From Darkness into Light: Factors Controlling Photomorphogenesis

A seedling that emerges in darkness follows a developmental program known as skotomorphogenesis (dark development), which is characterized by etiolation, that is, a long, spindly hypocotyl and pale cotyledons and inhibition of chlorophyll and anthocyanin biosynthesis and true leaf development. Upon exposure to light, the seedling switches rapidly to photomorphogenesis (light development); the h...
