Under the surface, the brain seethes with undiscovered activity
...neural traffic of a conscious brain as part of the equation
let Weliky get a better idea of the actual processing going on. As it turned out, one of his control tests yielded insight into neural activity no one expected. When the ferrets were in a darkened room, Weliky expected their visual neurons to lack an...
Vioxx: An unequal partnership between safety and efficacy
...product. Clearly, this is an immensely complicated equation
involving, among other factors, the nature of the condition being treated, the therapeutic strategies already available, and the perceived benefit-to-hazard ratio of the new treatment. The Vioxx story is one of blindly aggressive marketing by Merck ...

is more complicated. "Our study, although somewhat consistent with previous studies, shows that the relationship between the prevalence of periodontitis and income and education is different across racial/ethnic groups," Borrell says. Periodontitis i...
UCSD study cites lack of vigorous exercise as primary factor in adolescent obesity

when considering the population-wide increase we've seen in overweight in this age group in the past couple of decades. Insufficient physical activity and too much time spent on sedentary behaviors like computer games and watching TV may equal, and ...
Moderate-fat diet is kinder to heart than low-fat diet, study by UB researcher shows

Estimating the risk of cancer
...nd, a combination of the two modules results in an equation
in which the life expectancy depends on the food consumption and body growth. For fully-grown animals, the model simplifies to another, already well-known model. This enabled the researcher to ascertain how the parameters of this known model depend o...
