Eye thermal radiation can indicate a disease even before clinical signs appear

The eyes are not only a mirror of a soul, but also a medical record. Their thermal radiation can indicate a disease even before clinical signs appear. Investigations in this area conducted by Russian scientists have been supported by the research program of the Russian Academy of Sciences called “Abstract Sciences for Medicine”.

Variation in a taste receptor gene influences taste sensitivity

Variation in a taste receptor gene influences taste sensitivity of children and adults, accounting for individual differences in taste preferences and food selection, report a team of researchers from the Monell Chemical Senses Center. In addition to genes, age and culture also contribute to taste preferences, at times overriding the influence of genetics.

Medical experts have proposed associations between birth size and rates of adult cancer. To examine this hypothesis, researcher Valerie A. McCormack and colleagues at the London School of Hygiene & Tropical Medicine and the Universities of Uppsala and Stockholm investigated overall and site-specific cancer incidence in relation to birth characteristics in a Swedish population-based cohort.
