From the corner of the eye: Paying attention to attention
...s. Salk Institute neurobiologists are beginning to tease apart the complex brain networks that enable humans and other higher mammals to achieve this feat. In a study published in the July 5, 2007 issue of Neuron, the researchers report two classes of brain cells with distinct roles in visual attention,...Soil particles found to boost prion's capacity to infect
...andscape and that scientists are just beginning to tease out factors in soils that may contribute to transmissibility. The new study implies, he says, "that some soils may promote the transmission of the prion agent more readily than others." Why that's the case is unknown, Pedersen explains, but the Wis...Stressed-out African naked mole-rats may provide clues about human infertility

... Tardunos research, the only data scientists could tease from the rocks suggested the field was perhaps only a tenth as strong as todays. Tarduno had previously shown that as far back as 2.5 billion years ago, the field was just as intense as it is today, but pushing back another 700 million years in time ...Survey finds perceived risk of recurrence low in African-American breast cancer survivors
...she and a team of researchers at Penn attempted to tease apart the factors that might lead to this disparity, one of which, they believe, is the way survivors think about time. "Attitudes about time are aspects of a cultural worldview," Halbert said. "We thought, based on earlier work, that African Amer...'Electric' fish shed light on ways the brain directs movement
