Science Rocks. Babies Rock!

Please do not believe that babies are capable of self soothing. They are not. It is important to comfort them whenever they need. Being left to self sooth causes them to give up crying and seeking out but the body continues in a state of distress. Dissociation between behavior and the body is not a sign of calm.

Help kids ! Because children Rock!

the American Academy of Child and Adolescent Psychiatry, in a 2012 statement, concluded that,

…although corporal punishment may have a high rate of immediate behavior modification, it is ineffective over time, and is associated with increased aggression and decreased moral internalization of appropriate behavior.

In 2011, the National Association of Pediatric Nurse Practitioners (NAPNA) issued a statement noting that,

Corporal punishment (CP) is an important risk factor for children developing a pattern of impulsive and antisocial behavior…[and] children who experience frequent CP… are more likely to engage in violent behaviors in adulthood.

A new window into attraction! Science Rocks

Physical attraction linked to genes that control height

Some may believe that chance brings you together with your loved one, but scientists have found a far less romantic reason. Mate choice is influenced by our genes, in part by those responsible for our height.

An analysis of the genotype of more than 13,000 human heterosexual couples found that genes that determine your height also influence your choice of mate by height. This provides more understanding into why we choose partners of a similar height.

Over the last century, numerous studies have found that height was a key trait when choosing a mate, but until now there has been no explanation for this preference. This study investigates both, individual physical traits in relation to mate choice and the role played by underlying genetic variation.

Lead author, Albert Tenesa, from University of Edinburgh, says, "Our genes drive our attraction for partners of similar height to ours, i.e. tall people pair with tall people. We found that 89% of the genetic variation affecting individual preferences for height and one's own height are shared, indicating that there's an innate preference for partners of similar height."

Our height is determined by a combination of genetic and environmental factors. Using height as a model physical trait of attractiveness, the researchers sought to determine whether sexual attraction is driven by genes controlling a preference for a mate's height. They investigated whether the genes controlling your own height influence your preference for a mate of similar height to you.

Our genes can be used to predict the height of our partner. Albert Tenesa says, "Using one partner's genes for height, we estimated the height of the chosen partner with 13% accuracy. The similarity in height between partners is driven by the observed physical appearance of the partner, specifically their height, rather than influenced by the social or genetic structure of the population we live in."

Using white-British male and female pairs the team analyzed to what extent attraction to a mate of similar height was explained by a person's genetic make-up. The analysis provided correlations between one's own height and one's genetic make-up. These correlations indicated that genotype (one's genetic make-up) determines not only phenotype (one's physical appearance), but also one's preference for a mate with a particular appearance.

Mate selection driven by one's height is more than just a chance event and has important social and biological implications for human populations. The mating pattern observed for height is known as assortative mating, a mating pattern where individuals of similar physical characteristics mate more frequently than expected by chance. Assortative mating influences how DNA variation is arranged in the genome, which may have important implications for other human traits including disease susceptibility.

This study brings researchers closer to understanding the mechanisms that govern sexual attraction and those that drive human variation.

Your nose and your weight?!

Heightened ability to imagine odors linked to higher body weight

The John B Pierce Laboratory
The ability to vividly imagine the smell of popcorn, freshly baked cookies and even non-food odors is greater in obese adults, new research suggests. Vivid mental imagery is a key factor in stimulating and maintaining food cravings, which can be induced by the thought, smell and sight of food, say authors of a new report on the work.

Neuroscience Rocks! Memory Consolidation.

"It takes a few hours for new experiences to complete the biochemical and electrical process that transforms them from short-term to long-term memories. Over time, they become stronger and less vulnerable to interference, and, as scientists have argued for nearly a century, they eventually become imprinted onto the circuitry of our brains. That process is referred to as consolidation. Until recently, few researchers challenged the paradigm; the only significant question about consolidation seemed to be how long it took for the cement to dry."

But now a great deal of information is becoming available and how incredible this time in Neuroscience is turning out to be.

A fascinating article by Michael Specter about rewriting our traumatic memories. Neuroscience has come a long ways.
