Girl Power or: Partnership status and the human sex ratio at birth: a paper by Karen Norberg

Could the sex of a child be influenced by the status of the parents' relationship at the time of conception? In a sample of 86,436 births in the United States, we find a small excess of sons among births to parents who were married or living with an opposite sex partner before the child's conception, compared to births to parents who were not. This is the first evidence that household arrangements can affect the human sex ratio at birth, and could explain the fall in the proportion of male births in some developed countries over the past thirty years.

You get the gay from your mother

You get the gay from your mother.
It turns out that there may not be "gay" genes, just "attracted to men" genes.

Science

In terms of our genes, we humans are all the same -- except for the ways in which we're different. Pharmacogenomics has for years been touted as the ultimate benefit of the genomics revolution. But to many, this revolution has a troubling side.

Patenting Genes

Monsanto Wins Fight to Control Plant The Canadian Supreme court sets international precedent by ruling that since Monsanto holds a patent on a gene, it can control the use of the plant. So does this mean that in the future that an engineered human gene could be patented, and therefore if you receive this gene you will have to make royalty payments? And if you renege on paying can they repo the gene?

Send in the clones

Godsend Institute offers up this explanation of their cloning procedures. Since Dolly, several scientists have cloned other animals, including cows and mice. Now, at Godsend, we have pioneered a technique that allows a cell nucleus from a recently deceased child to be implanted within a human egg, allowing a mother to carry that child to term again.

Challenging Darwin: Is sex really all about the genes?

Author challenges Darwin's theory of "sexual selection." To Darwin, mutations that don't enhance survival, like peacocks' tails, must be aids to attracting mates to pass on genes. Homosexuality, therefore, is to Darwin and the Christian-right both an unnatural aberration. But with ever growing evidence of homsexual behavior in animals, from bonobos to penguins, isn't it time that Darwin's theory get replaced?

Making the Mind

Making the Mind. "The general outlines of how genes build the brain are finally becoming clear, and we are also starting to see how, in forming the brain, genes make room for the environment’s essential role. While vast amounts of work remain to be done, it is becoming equally clear that understanding the coordination of nature and nurture will require letting go of some long-held beliefs."

Genetic Sexual Attraction

A new brand of incest. "You're 40, happily married - and then you meet your long-lost brother and fall passionately in love. This isn't fiction; in the age of the sperm donor, it's a growing reality: 50% of reunions between siblings, or parents and offspring, separated at birth result in obsessive emotions. Last month, a former police officer was convicted of incest with his half-sister - but should we criminalise a bond hardwired into our psychology?"

This is Bob. Bob has bitch tits.

Breasts on men — most people's only knowledge of this stems from Fight Club (his name was Robert Paulson), but Gynecomastia is a very real medical condition, often a side effect of Klienfelter Syndrome. This person's experiences with their gender identity (raised primarily as a girl, then switching to being publicly masculine when older) while growing up with Gynecomastia in a small town fascinated me.

The human genome and the new eugenics

"We are becoming the masters of our own DNA. But does that give us the right to decide that my children should never have been born?" John Sundman is a science fiction novelist and the father of two children with severe medical conditions. In this two-part article he shares his experiences and thoughts on bioethics, the Human Genome Project and whether genetics research is paving the way for a resurgent eugenics movement.

I yearn for your tasty flesh

[ Gene Study Finds Cannibal Pattern ] - "Deep in the recesses of the human heart, lurking guiltily beneath the threshold of consciousness, there may lie a depraved craving — for the forbidden taste of human flesh. The basis for this morbid accusation, made by a team of researchers in London, is a genetic signature, found almost worldwide, that points to a long history of cannibalism" (NYT)

Toughness Gene

Those crazy scientists have discovered a gene that determines how sensitive somebody is to pain. The gene comes in two forms, and you get one from each parent, so a quarter of the people end up tough, half end up in the middle, and the other quarter comprise of wusses. Interesting stuff.

Dolly is dead. "The type of lung disease Dolly developed is most common in older sheep. And in January 2002, it was revealed that Dolly had developed arthritis prematurely. She was cloned using a cell taken from a healthy six-year-old sheep, and was born on 5 July 1996 at the Roslin Institute, Edinburgh, Scotland."

That means no Planet of the Apes II, I guess

Going bananas. The only fruit to ever appear on a Velvet Underground album cover (not to mention the title of a J. D. Salinger short story) may be on its way to extinction. Facts: I) total disappearance could occur within a decade; II) bananas are the staple diet for half a billion people and III) current genetic tampering mean that, even if the fruit doesn't quite disappear, it will taste and look different (Guardian article here).

Since Genetically Modified Organisms are a big no-no in Europe, some scientists are now focusing their efforts on TILLING (Targeting Induced Local Lesions in Genomes), a novel technology for rapid selection of a mutation in any gene from mutant plant, through the use of a mutagen, Ethyl Methanesulfonate (EMS). Will this method be seen as less dangerous than Genetic Engineering à la Monsanto? During my search on this topic, I stumbled on this entertaining story about DIY genegeneering.

They're farther along than I thought...

They're farther along than I thought... You may have heard about Nexia Biotechnology, who have put spider genes into goats to get milk with spider silk protein in it. I thought it was still in the research phase, but Nexia have apparently gone to market with the stuff. They've signed agreements with several manufacturers to produce spider silk protein-based products such as lightweight ballistic armor (like Kevlar, only lighter and non-toxic to produce) for the armed forces and super-strong sutures and prosthetic ligaments for medical supply companies.

The Icelandic company Decode Genetics

The Icelandic company Decode Genetics may have the lead in creating a catalog of the deviant genes that cause most diseases. Led by Dr. Kari Stefansson, the project uses a novel combination of genotyping living Icelanders and comparing the results to Iceland's unique genealogical database that extends back 1100 years. With Iceland's other project to completely switch from fossil feuls to hydrogen power, my admiration for that island of Vikings keeps growing stronger.

Are heart disease, cancer and schizophrenia caused by pathogens?

Are heart disease, cancer and schizophrenia caused by pathogens? The logic basically goes that a genetic disease cannot have a very high rate of occurrence as natural selection would prevent that gene from surviving (leaving the few occurrences of the disease that are caused by random mutation). Also: how to make diseases more benign by altering the parameters to their natural selection.
