Environment, Lifestyle Factors Determines Changes In Pain Sensitivity

Ranjini Raghunath for redOrbit.com - Your Universe Online The way you react to pain keeps changing throughout your lifetime, influenced by lifestyle and environmental factors, a new study carried out by researchers at King’s College London suggests. The study identified genetic changes that determine how different people – even identical twins -- react to pain differently. The results from the study could help scientists understand how pain sensitivity differs in individuals, and...

The fact that taller people also tend to be slightly smarter is due in roughly equal parts to two phenomena—the same genes affect both traits and taller people are more likely than average to mate with smarter people and vice versa—according to a study led by the University of Colorado Boulder. The study did not find that environmental factors contributed to the connection between being taller and being smarter, both traits that people tend to find attractive. The modest correlation...

Does Dad's stress affect his unborn children? According to the results of a new study in Elsevier's Biological Psychiatry, it seems the answer may be "yes, but it's complicated". The risk of developing depression, which is significantly increased by exposure to chronic stress, is influenced by both environment and genetics. The interplay of these two factors is quite complex, but in fact, there is even a third factor that most of us know nothing about — epigenetics. Epigenetics is...

(Ivanhoe Newswire) -- A specific genetic defect in one Chinese family shows that high blood pressure was inherited from the mother. The defect results from the substitution of a single DNA "base" for another during replication in the genes of a tiny cellular organ called the mitochondria, which generates a cell's energy. When reproductive cells come together to form an embryo, the mitochondrial DNA from the mother cell is passed on to the offspring. Evidence has suggested a mother-child...

Early 20th century evolutionist may have discovered epigenetics A new study into the research of the renowned Lamarckian experimentalist Paul Kammerer may help to end the controversy which has engulfed his research for almost a century. The study, published in The Journal of Experimental Zoology, suggests that far from being a fraud Kammerer may have discovered the field of epigenetics, placing him decades ahead of his contemporaries. Paul Kammerer, a leading proponent of the Lamarckian...

Article reviews evidence for epigenetic inheritance in wide range of speciesFor years, genes have been considered the one and only way biological traits could be passed down through generations of organisms.Not anymore.Increasingly, biologists are finding that non-genetic variation acquired during the life of an organism can sometimes be passed on to offspring"”a phenomenon known as epigenetic inheritance. An article forthcoming in the July issue of The Quarterly Review of Biology lists...

Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House. So why couldn't Darwin have done it too? A Journal of Biology article* argues that Darwin's background, influences and research focus gave him a viewpoint that prevented him from interpreting the evidence that was all around him, even in his own work. Darwin's commitment to quantitative variation as the raw material of evolution meant he could not see the logic...

CAMH study reveals that heritability may not be limited to DNA Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases. These findings challenge the fundamental principles of genetics and inheritance, and potentially provide a new insight into the primary causes of human diseases. Your mother's...
