  • BEING a nice person could come down to having a good set of genes
  • "kind" behaviour of more than 700 individuals was partly linked to receptor genes for oxytocin and vasopressin.
  • uch of the hormone you have, it's how responsive your brain is to the hormo

  • It's not about how much of the hormone you have, it's how responsive your brain is to the hormones
  • "(Niceness) is a combination of genetics and your environment."
  •  
    A study shows that genetics could play a role in determining "niceness". The kind behavior is found to be linked to receptor genes for oxytopic and vasopressin. People that are more responsive to it are more inclined to donate money, pay taxes, give blood, report crime etc. It isn't about how much of the hormone you have but how responsive you are to it. Of course genetics isnt the only factor, if you are surrounded by nice people it is likely that it would rub off on you.

Epigenetics Seeks Clues to Mental Illness in Genes' Life Story - Science in 2011 - NYTi... - 0 views

  • epigenetics, the study of how people’s experience and environment affect the function of their genes.
  • Studies suggest that such add-on, or epigenetic, markers develop as an animal adapts to its environment, whether in the womb or out in the world — and the markers can profoundly affect behavior.
  • In studies of rats, researchers have shown that affectionate mothering alters the expression of genes, allowing them to dampen their physiological response to stress. These biological buffers are then passed on to the next generation: rodents and nonhuman primates biologically primed to handle stress tend to be more nurturing to their own offspring, and the system is thought to work similarly in humans.

  • the offspring of parents who experience famine are at heightened risk for developing schizophrenia, some research suggests — perhaps because of the chemical signatures on the genes that parents pass on.
  • in some people with autism, epigenetic markers had silenced the gene which makes the receptor for the hormone oxytocin. Oxytocin oils the brain’s social circuits, and is critical in cementing relationships; a brain short on receptors for it would most likely struggle in social situations.
  • In one large study of people with schizophrenia, researchers at Johns Hopkins are analyzing blood and other data to see whether the degree of epigenetic variation is related to the inherited risk of developing the disorder. In another, researchers at Tufts are studying the genes of animals dependent on opiates to see how epigenetic alterations caused by drug exposure affect the opiate sensitivity of the animals’ offspring.

Genetic adaptation of fat metabolism key to development of human brain - 0 views

  • 300,000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans.
  • higher risk of developing disorders like cardiovascular disease.
  • investigated the genes for the two key enzymes that are needed to produce Omega-3 and Omega-6 fatty acids from vegetable oils.
  • ...7 more annotations...
  • genetic adaptation for high production of Omega-3 and Omega-6 fatty acids is found only in humans
  • 300 000 years ago in the evolutionary line that led to modern humans
  • important factor for human survival in environments with limited dietary access to fatty acids
  • In today’s life situation, with a surplus of nourishment, this genetic adaptation contributes instead to a greater risk of developing disorders like cardiovascular disease
  • first study to show a genetic adaptation of human fat metabolism
  • thrifty gene
  • adaptation that contributed to enhanced survival in an earlier stage of human development, but in a life situation with an excess of food instead constitutes a risk factor for lifestyle diseases
  •  
    This article explains how earlier genetic adaptations that help our survival is now harming us.

Genes Are No Crystal Ball For Disease Risk - Science News - 0 views

  • For all but four diseases, the genetic data would fail to determine who is likely to contract the condition in most cases,
  • genetics are only part of the story when it comes to determining health. Lifestyle, environment and random chance play a bigger role than genes, or work with genes, to cause or protect against disease.
  •  
    Looking at twin data, researchers found that genetics alone could not account for the risk of disease.

A new class of obesity genes encodes leukocyte adhesion receptors - 0 views
