Genetically Modified Babies?

How would you like to “design” a baby? What if you could give the baby George Clooney’s eyes or Cindy Crawford’s…everything? While the science of making these “alterations” is limited, there is concern for that possibility becoming a reality in the future with a recent procedure being cleared for approval in Britain last week.

The fertility procedure, which is banned in the United States, is called mitochondrial transfer technique, or mitochondrial replacement therapy, and it helps to prevent children from being born with deadly genetic diseases. In particular, this procedure is an attempt to treat mitochondrial disease.

Mitochondrial mutations—which are linked to fatal diseases involving the heart, nerves, skeletal muscles, brain, liver, kidneys, and the endocrine and respiratory systems—are caused by defective mitochondria (small structures in almost every cell responsible for converting food into useable energy).

Mitochondrial flaws are typically passed down from the mother, which explains, in part, how this technique works:

The technique involves using a donor egg in addition to the mother’s egg and the father’s sperm. The goal of the procedure is to get healthy mitochondria from the donor. The donor egg’s nucleus is extracted and replaced with the nucleus from the mother’s egg—thereby getting rid of the diseased mitochondria.

Doctors from New York performed the procedure in Mexico and the resulting baby, born a few months ago in New York, is, by all accounts, healthy. The parents who participated in the procedure had only ever experienced having children born with extreme disabilities passed on from the mother’s mitochondrial flaws. For the first time, they have a healthy baby.

And while the headlines surrounding this story have largely been focused on the three-parent angle, the donor’s DNA will have no impact on the physical or personality traits of the resulting baby. All of the physical and personality traits still come from the parents and not from the minute amount of donor DNA.

So why isn’t this procedure approved in the U.S.? What gives opponents pause?

Ethical questions persist! Opponents typically object to the procedure because it deals with the manipulation of genetic matter. There is also concern over this procedure ultimately paving the way for genetically modified babies. That is, being able to select the physical traits of an unborn child.

Do you think this procedure could pave the way for genetically modified babies?

Do Women Like Jerks?

Posted July 19, 2012 6:56 AM by HUSH

Zach pulled his Ford into Kelly's driveway, flicked his lights off, and unbuckled his seat belt. Kelly opened her car door, and Zach was holding her coat while she looked for her keys in her purse. They had a nice evening; they ate a cliché dinner at the Cheesecake Factory, and then saw a movie: Harry Potter and I Can't Believe this Franchise is Still Going. Zach wanted to see Total Recall, but sacrificed his want to make Kelly happy.

Kelly jingled her keys, and looked at Zach blankly. Zach leaned forward, puckered his lips…and Kelly slouched away.

"Oh, no. Oh, jeez. I'm sorry Zach, I just don't see you that way. You're a great friend, but you're that, a friend." Kelly went inside, and didn't return Zach's phone call the next day.

A week later Zach learned that Kelly has been dating A.C. Slater. Slater wasn't nice, didn't take Kelly out on dates, and was arrogant. Slater was a jerk, and Kelly loved him.

...via NY Post

There is an underlying mythos in the dating world that women like jerks. Something about their cockiness or selfishness just makes women fascinated--or at least, allegedly so.

Is it true? Do women really want guys who walk all over them? It doesn't seem to make sense. People are drawn to people with similar interests, who are polite, and unlikely to misplace trust.

Let's see what some experts have to say on the matter, shall we?

Let's further define 'jerk' so we have a basis from which to compare. While Urban Dictionary lists it as, "The kind of guy most girls ACTUALLY want," I prefer's version: "A contemptibly naive, fatuous, foolish, or inconsequential person." Other adjectives that may describe a jerk: stubborn, critical, aggressive, and disagreeable.

Physcologist Scott Barry Kaufman wrote that when analyzing how mating was related to certain character attributes, he noticed one glaring connection: The lower the level of agreeableness, the more sexual partners.

Similarly, this study indicates that the so-called "Dark Triad" traits (narcissism, psychopathy, and Machiavellianism) are good indicators of short-term heterosexual relationships. Or, to be blunt, booty-calls and hook ups. While these were a predictor of sexual partners, they also predicted long-term relationships would be unsuccessful and mostly unhappy. Specifically, narcissists seek social environments in which to validate their ego, which only strengthens the personality qualities women find attractive. Those being: confidence, creativity, humor, charisma, and high energy. Essentially, if the male is more comfortable in a setting, he is more likely to find a sexual partner. The most comfortable of men are those who are unafraid of their social stature, hence the attractive qualities of narcissists.

Want to see where you stand in the Dark Triad?

...via Terra Incognita

Part of the allure of a jerk could be a little bit of conditioning as well. Jerky guys tend to be non-committal towards females. Jen Kim, of Psychology Today, wrote:

Women want some chase, some drama, some intrigue. If it's too easy to get the guy, then she might think, "Wait, he just fell into my lap. This is fishy. Maybe he thinks that I'm too good for him. Cool. I'm too good for him. Wait, if I'm too good for him, then that means I could do better. Next!" I hate to say this, but this thought has crossed my mind (and I'm sure others' as well) more than once.

There is one glaring conflict though: in Chelsey H's blog, "What Women Want," she mentions that women are attracted on a biological level. Aren't these traits exactly what women are trying to avoid? You know, further depreciation of her offspring's potential gene pool?

Matt Huston, former editor of Psychology Today, theorizes that being a jerk is actually an indicator of good genetics, and not bad genetics. These individuals essentially, can "put their money where their mouth is" by taking risks from being a bad boy, and are better emotionally developed (hardened?) to take the consequences of being a jerk and build upon them. A VERY similar concept has been put forth, but related to salary. Timothy A. Judge's study suggests that disagreeable men get further in the business world by taking risks, and though they are more likely to get fired than a 'yes man,' they're also more likely to get a new job at a better wage. In fact, disagreeable men make 18% more annually than agreeable men-averaging $10,000!

...via Atomic Movie Freak

While I've seemed to make a good case for treating your girlfriend horribly (which, for the record, I do not condone; I don't know why I need to make that clear …) there is one issue I need to circle back too: long term relationships. Just as the Dark Triad-or the jerk traits-tend to indicate a good number of sexual partners, they also indicate long-term relationship success. Or rather disaster. Higher scores of narcissism and psychopathy predict unhappy long term relationships-or more accurately, no long term relationships. These traits are in direct conflict with compromise and compassion, two highly-heralded pillars of relationship success .

Do women like jerks? Do nice guys finish last? It seems it depends on the race. In the sprint for sex, jerks will take the tape. But in the marathon setting of a long term relationship, jerks are left for dead with heat exhaustion .

You Found Love Where?

Posted July 05, 2012 12:00 AM by Chelsey H

Hearts equal love. At least that's what Valentine's Day and pop culture has instilled in us. However, how the <3 became a symbol for love is an interesting but rather long-winded story. And as romantic as a broken-heart sounds, love actually originates in the brain. What makes this even more confusing is being able to distinguish between love and desire. Both mental states are invoked by an intense longing to be with another person, and are therefore often difficult to disentangle from one another.

Image Credit:

A recent international study published in the Journal of Sexual Medicine has been the first to draw an exact brain map of love and desire. Although the scientists were skeptical, they found that love and desire activate specific, but related areas in the brain.

Many studies have been done to examine the brain while subjects engaged in tasks such as viewing erotic pictures or looking at pictures of their significant others. The group analyzed the results of 20 of these studies. They found that the insula, located deep in the cerebral cortex, and the striatum, located in the forebrain, are responsible for tracking the progression from sexual desire to love. The two emotions activate different parts of the striatum. Sexual desire activates an area of the striatum associated with things that are inherently pleasurable, such as sex or food. Love activates an area associated in the process of conditioning by which things are paired with reward or pleasure, and are given inherent valve. This means that as sexual desire turns to love, they are processed in different parts of the striatum.

What I found interesting is that this area of the striatum is also the part of the brain associated with drug addiction. This makes sense, since love is actually a habit. It's formed when the desire part of 'sexual desire' is rewarded (and subsequently can be hard to break the habit.)

And while there are always extreme cases, love in general is not considered a bad habit. Love works with different pathways in the brain that are involved in monogamy and in pair bonding. It can actually decrease activity in certain parts of the brain when it is not associated with desire. "While sexual desire has a specific goal, love is more abstract and complex, so it's less dependent on the physical presence of someone else," says Pfaus, a professor at Concordia University.

Is Infidelity Predicatable?

Posted June 21, 2012 7:17 AM by HUSH

So…we're again reaching into the back of HUSH's mind to produce an anecdote that will segue into a good CR4 post for Courtship Chemistry. Are you prepared? I'm not.

A couple years ago, I was dating a very beautiful woman. Think Vicki Vale kind of beautiful. Anyway, we had spent about three months casually seeing each other, but we never had "the talk." The talk I'm referring to, of course, is the one that defines a couple's relationship. If "the truth shall set you free," then the talk will deprive you equally so.

...via Bernos

Yet, there can be a damning grey area before this talk arises. And in the case of my Vicki Vale, my procrastination of the talk tempted Vicki to the fruit of another. It was a lesson learned the hard way, as lessons of love are often taught.

I wonder though, what made Vicki consider her options? Is there a scientific conclusion? And even if Vicki didn't cheat, what causes infidelity. I did some digging, so let's see what you think about my shallow conclusions from what I found. Mmmmkay?

...via Sure Villa

It turns out fidelity is linked to something called 'attachment theory.' Essentially, attachment theory explains how people think, feel and behave in interpersonal relationships. Humans have their first experiences with attachment theory during the toddler stages of life, where the youngster uses their parents as a springboard and emotional measuring stick for their physical actions. The style of attachment between the parent and the child can be boiled down to one of four styles.

...via Wikimedia

These four styles of attachment roughly translate to romantic and sexual adult relationships. The four types of attachment for adults are secure, anxious-preoccupied, dismissive-avoidant, and fearful-avoidant. Securely-attached individuals are confident of their partners and relationships, and can develop a good balance of intimacy and independence. Anxious-preoccupied adults are very dependent, and seek approval and response from the partners often. These individuals are less confident of their relationships and partner, and are more prone to worry and emotional impulsiveness. Dismissive-avoidant attachment styles are characterized by suppressed feelings, extreme independence, and low-opinions of their partners. Like dismissive-avoidant individuals, fearful-avoidant individuals suppress emotions, but often believe they are the ones unworthy in the relationship.

Out of these four, secure individuals are the least likely to cheat on their partners, while anxious-preoccupied individuals are most likely to cheat. This is due to their extreme need for approval and attention, and even a mild affection holdout from their significant other could be enough to push them to "the cheating side of town." Avoidant-attachment individuals tend to have "average" rates of cheating, or at least median rates.

...via Venus Genus

However, if we're looking at cheaters as individuals, it's probably worth looking at the subjective nature of cheating. Some people may thinking cheating starts at flirting, and others may say it starts when "the nipple makes its first appearance."

Studies have found that twice as many men as women say they'd be upset more by sexual infidelity than by emotional infidelity. This could be traced back to an evolutionary behavior providing incentive for both partners. If a woman becomes impregnated by another man, then her spouse loses her ability to reproduce for at least nine months, and he'll be left with another man's child which could take resources from his own offspring. This is in contrast to if a woman developed feelings for another man, but she did not have intercourse with that man. On the flip side, a woman would care more about her male mate's emotional infidelity, because that is essentially what commits the man to the woman, the family, and their preservation. Intercourse outside of this relationship is less likely to lead to him abandoning her than if he were to develop feelings for another woman.

...via Author's Den

That's not to say males were unconcerned with the affections of their women, or that women were unconcerned with where their husbands may lie at night. Evidence only suggests that these factors are diminished in comparison. Evidence also suggest that because of the traditional male role model (tough, domineering, emotionless), men are more likely to have dismissive or fearful-avoidant attachment styles, while women-whose traditional gender roles (yuck!) instill compassion and emotional development-are more likely to have secure attachment styles. Again, we're speaking in generalizations here, so deviations always occur.

Does that make men more likely cheat? Not so, says Men's Health, who-not surprisingly with its readership base-lays the blame of male cheating on the biological need to reproduce, inattentive spouses, and boredom.

...via How to Stop Divorce

Does the perception exist that men cheat more than women? Yes. In large part this is from media coverage. TIME author Jeffrey Kluger believes that cheating men are more visible because they abuse their power. Think Bill Clinton, Arnold Schwarzenegger, and Tiger Woods. Kluger also believes that there is more public outcry, and therefore coverage, because these already successful men are living a life provided the admiration of proletariat, and they should have the moral fiber not to abuse it.

So, let's get a wrap on this. Was HUSH's Vicki Vale one of many wolves in a sheepish disguise? It seems more likely that men and women cheat at about the same rate . However, some recent studies have signaled that women cheat more than men; they're just better at keeping it a secret.

What Women Want

Posted June 07, 2012 3:24 PM by Chelsey H

So as promised, here is your follow up to 'You "Type" is More Mind Than Media'. I'm calling it "What Women Want." It really should be called "what women are biologically programmed to think they need," but that's not a very catchy title.

Men typically are not very good at sending or receiving the signals used in the courtship ritual. The book The Definitive Book of Body Language states, "women not only control the game and make the rules, they own the scoreboard." In the animal kingdom, the male of a species tends to be more colorful and use flashy, and sometimes absurd rituals to attract a female mate. For humans, the primary displays that men use are their power, wealth, and status. In lieu of dressing sensually, or wearing makeup, men will rev their car engine, brag about their salaries, and challenge other men which, in most cases, isn't very effective. Still, they do subconsciously send out other signals that encourage attraction in either direction.

Similar to women, men display preening behavior in the presence of the opposite sex. Today, more than ever, men are spending more time and money on personal grooming. This behavior may manifest itself as him straightening his tie, touching his cufflinks or watch, and rearranging his shirt, coat, or other clothing. But the most direct sexual display a man can make is the 'Thumb-in-Belt' gesture that highlights his crotch. This may be combined with turning his body to her, use of an intimate gaze and holding that gaze for longer than usual. When sitting or standing a man may spread his legs to not only display his crotch, but to take up more of the space to seem bigger and more dominating. Much to the dismay of women, men will also use crotch adjustments to assert masculinity in front of others. This is especially true on sporting teams or other groups that encourage macho attitudes.

As for what women are attracted to, in general women prefer men with a deeper voice, athletic body shape, broad shoulders, muscular chest and arms, and a tight butt. Just like men, women fall into three distinct categories for what parts of a man's body they are most attracted to: chest/arms, butts, and legs.


Men have a distinct upside-down-triangle shape, which is opposite of the women's right-side-up body shape. Sexy, as defined by the book and blog, is the distinction between the sexes so a man who has broad shoulder is highlighting this difference. These features evolved to allow them to carry weapons and food over long distances. The male chest developed to house large lungs to allow for better breathing when running and chasing. In past generations, and in many animal species, the bigger the man's chest, the more power he has in a group.

There is such a thing as too much muscle though; it makes a woman think you care more about your appearance than theirs.


Surprisingly, butts are considered the favorite part of a man's body with 40% of the votes. But I bet many women don't know why. Women are attracted to a small, tight butt because it's a sign that the man can make the necessary forward thrusting motion needed for reproduction.


Back to the triangle- the ideal man's body has broad shoulders and narrow hips with muscular legs. It's not that women are actually attracted to the legs, as much as they are attracted to the symbol of power and endurance that they display. According to Dr. Devendra Singh, women find male hips with a 90% waist-to-hip ratio the most appealing.

This book also gives men a sneaky hint that, even as a woman, I admit to be true. If a man wants to find out which women find him attractive, he should wear his tie a little to one side. A woman who thinks you're good looking can't resist straightening it out for you.
