Monsanto Is Going Organic in a Quest for the Perfect Veggie - "The lettuce, peppers, and broccoli—plus a melon and an onion, with a watermelon soon to follow—aren't genetically modified at all. Monsanto created all these veggies using good old-fashioned crossbreeding, the same technology that farmers have been using to optimize crops for millennia. That doesn't mean they are low tech, exactly. Stark's division is drawing on Monsanto's accumulated scientific know-how to create vegetables that have all the advantages of genetically modified organisms without any of the Frankenfoods ick factor."

"‘The gene does not lead,’ she says. ‘It follows.’"

The selfish gene is one of the most successful science metaphors ever invented. Unfortunately, it’s wrong.

Intelligence Tests

Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g." [more inside]

Make Babies

"Older parenthood will upend American society." "Is waiting to have kids a big mistake?" "Why do women believe they can delay children for so long?" "Older men are more likely than young ones to father a child who develops autism or schizophrenia, because of random mutations that become more numerous with advancing paternal age."

Cat Color Genetics

After decades of breeding, the complexity of cat color genetics is quite well understood. Genes which control pigmentation, hair length, color dilution, banding (agouti), white fur (dominant, spotting, or albino, sometimes linked with deafness), tabby patterns, and more combine to create a wide spectrum of possibilities. Specific traits such as white gloving among Birman cats and the amber color found only in Norwegian Forest Cats (which comes from a single female born in 1981!) have also been isolated and studied, and can be affordably tested for. On top of all that, fur color is epigenetic as well as genetic, and sometimes responds to the cat's environment. If you clone a calico cat, you get a kitten which doesn't have a similar coat due to X-inactivation, and pointed cats (such as Burmese, Siamese, and Tonkinese) have temperature-sensitive coloration.

Mushroom Sex

"People who use sows to hunt for truffles often find it hard to prevent a sex-crazed animal from eating the truffle she has found and may lose fingers in the attempt." (via) The NYT on decoding the genome of the Périgord Black Truffle . Attempts to make truffles cheaper and more accessible in the past have been met with some resistance.

Learn.Genetics

grumblebee's post about cell size and scale the other day was quite fascinating. Pulling back to the home for that site, the Genetic Science Learning Center at the University of Utah delivers educational materials on genetics, bio-science and health topics ranging from stem cells to gene therapy, and from epigenetics to heredity. Explore the neurobiology of normal and addicted brains and the genetic contribution to this chronic disease.

Humans are evolving rapidly

Humans are evolving more rapidly than in the distant past, according to a new study published in PNAS. "The massive growth of human populations has led to far more genetic mutations, and every mutation that is advantageous to people has a chance of being selected and driven toward fixation. We are more different genetically from people living 5,000 years ago than they were different from Neanderthals", says lead author John Hawks. [more inside]

Kinseyian mathematics, of a kind

The "Darwinian paradox" of homosexuality presents the conundrum of how a potential genetic basis for homosexual behavior could provide a survival benefit to offpsring and extend through generations, when sexual reproduction would seem to place strong selection pressure against such a "gene". Recently developed mathematical models (PDF) from researchers Sergey Gavrilets and William Rice not only show how a "gay gene" might proliferate within a population, but also provides testable hypotheses, including predictions of "widespread bisexuality" (subscription req'd).

Ah, science.

New research takes steps towards finding the "gay genes." A study conducted on gay brothers in more than 100 families found several genetic regions of similarity with linkage to sexual orientation. This is kind of dense (scroll to the bottom of the page for the FAQ), but that's because it hasn't been written up in the press so there are only journal doc's and scientific summaries available.
This is the press release, which is clearer (Microsoft Word).
This is the article on the study, as published in the journal Human Genetics (PDF).

Taming of the Shrew

Extinct is forever. Or is it? Scientists are hard at work reconstructing entire genomes of our common ancestors. The present technology is a far cry from Jurassic Park, but we're getting there.

The Dawkins FAQ.

The Dawkins FAQ. Interesting Q&A session about evolution, biology, genes, etc with an expert. Dawkins claims no final answer on the "gay gene" or a Darwinian explanation of homosexuality.

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.

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?

Gene Prevents 'Brains Everywhere'

Gene Prevents 'Brains Everywhere' The human version of the gene probably is not involved in keeping the human brain inside the skull, but likely plays some other role in nervous system development in human embryos, says Alejandro Sanchez Alvarado, a developmental biologist at the University of Utah School of Medicine.

Orlando police find crack cocaine on Gov. Bush's daughter

Scientists are making DNA that uses letters other than AGCT

Scientists are making DNA that uses letters other than AGCT
Underlying the chemicals is a code. DNA is composed of pairs of four types of proteins. This project at Scripps Research Institute is attempting to design a DNA which uses different proteins to convey genetic information. The ultimate goal would be to have a functioning organism with a genetic code that uses a different "alphabet" to "communicate" the same "message" You know what this means? If they can get it to work, language wins! The world will truly be proven to be a "discursive" formation. (The language metaphor comes courtesy of the NYT, but I believe it is more than apt.)
