Hispanic Children Rarely Get Top-Notch Care For Brain Tumors

Hispanic children diagnosed with brain tumors get high-quality treatment at hospitals that specialize in neurosurgery far less often than other children with the same condition, potentially compromising their immediate prognosis and long-term survival, according to research from Johns Hopkins published in October’s Pediatrics.

More than a decade after the Institute of Medicine’s landmark report Crossing the Quality Chasm, the Hopkins investigators say their findings detect persistent gaps in access to specialized care among certain patients, raising questions about how far across the chasm we have actually come.

Study reveals how ‘world’s toughest bacterium’ survives lethal radiation

Listed in the Guinness Book of World Records as “the world’s toughest bacterium,” Deinococcus radiodurans can withstand extreme temperatures and drought conditions, lack of nutrients and a thousand times more radiation than a human being.

A new study by Cornell researchers reveals that nitric oxide — a gas molecule used in many metabolic processes in animals and a pollutant in the atmosphere that leads to smog — plays a key role in D. radiodurans’ recovery when exposed to ultraviolet radiation (UV).
