A new modeling approach using sea ice motion data to follow parcels of ice backward in time at monthly intervals for up to 3 years while accumulating a history of the solar radiation and air temperature to which the ice was exposed offers new hope for increased accuracy in climate change models, say scientists with the U.S. Geological Survey and the Russian Academy of Sciences, Moscow. This is the only model based entirely on historical observations.

Using this new technique, the thickness of Arctic sea ice was estimated from 1982 to 2003. Results showed that average ice thickness and total ice volume fluctuated together during the early study period, peaking in the late 1980s and then declining until the mid-1990s. Thereafter, ice thickness slightly increased but the total volume of sea ice did not increase.

A 10-cent pill doesn't kill pain as well as a $2.50 pill, even when they are identical placebos, according to a provocative study by Dan Ariely, a behavioral economist at Duke University.

"Physicians want to think it's the medicine and not their enthusiasm about a particular drug that makes a drug more therapeutically effective, but now we really have to worry about the nuances of interaction between patients and physicians," said Ariely, whose findings appear as a letter in the Journal of the American Medical Association.

Objectives.

Sepsis is a syndrome that results from a dysregulated host response to infection which can rapidly lead to organ dysfunction and death.
The aim of this study was the microbiological and clinical assessment of a new real-time PCR test (SeptiFast: SF, Roche Diagnostics) for the diagnosis of blood stream infections (BSI) in a population of neutropenic patients.
The results of SF were compared with blood cultures (BC) obtained on the same specimens and the clinical significance of the two methods was assessed.
