Dont curse the darkness light a candle

Better to light a candle than curse the darkness: illuminating spatial localization and temporal dynamics of rapid microbial growth in the rhizosphere

The rhizosphere is a hotbed of microbial activity in ecosystems, fueled by carbon compounds from plant roots. Basic questions about the location and dynamics of plant-spurred microbial growth in the rhizosphere are difficult to answer with standard, destructive soil assays mixing a multitude of microbe-scale microenvironments in a single, often sieved, sample. Soil microbial biosensors designed...

Sarcoma nomograms: a light over the darkness

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.

Is it better to shine a light, or rather to curse the darkness? Cerebral near-infrared spectroscopy and cardiac surgery.

Cerebral perfusion and good neurological outcome appear most obviously at risk during operations on the aortic arch. However, it is also evident that from a numerical standpoint, otherwise uncomplicated coronary artery bypass grafting (CABG) accounts for the greatest number of perioperative strokes, as shown in a review of 7839 patients in which it was determined that the overall incidence of c...

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...
