Decoding the logic of olfaction
...ve cells inside the nose. When an odorant receptor detects an odor molecule, it triggers a nerve signal that travels to a way station in the brain called the olfactory bulb. Signals from the olfactory bulb, in turn, travel to the brain's olfactory cortex. Information from the olfactory cortex is then sent to...New genetic test may detect risk of rare complication from anesthesia
...a patient suspected to be at risk for MH. The test detects 25 to 50 percent of the mutations known to make one susceptible to the condition. If physicians know that a patient has this genetic susceptibility, they can substitute other anesthesia drugs when surgery is required. Ronald S.

The test detects around 200 different volatile organic compounds in a single sample of breath, in distinctive patterns that can determine health or illness, Phillips said. From a patient's viewpoint, a breath test can reduce risk, pain and cost. For example, patients...Other highlights in the August 17 JNCI

Screening mammography detects breast cancers at an earlier stage of development than breast cancers detected symptomatically--the so-called stage shift--and so mammographically detected breast cancers tend to have better prognoses. This stage shift is subject to various biases, s...Insight into the processes of 'positive' and 'negative' learners
