Researchers in Israel and Illinois say they’ve found a second code in DNA, one that deals with the positioning of proteins. Palimpsest anyone?

The Blue People of Troublesome Creek. Due
The Blue People of Troublesome Creek. Due to a rare blood disorder, “four of the seven Fugate children were born with bright blue skin that lasted their entire lives.” “Over the years, the Fugates interbred repeatedly. Blue people proliferated.” (More here….scroll for the Science article.)

The Edge has a transcript and an mp3 recording of an event called The Selfish Gene: Thirty Years On. The speakers include Daniel Dennett and Richard Dawkins.
America’s Stone Age Explorers
Watched America’s Stone Age Explorers on PBS this evening, a summary of recent findings about who the first Americans were, where they came from, and when they arrived. Recent genetic and archeological evidence suggests they arrived earlier than generally accepted and may have originated from Europe rather than Asia.
To Dr. David Hague, human pregnancy is
To Dr. David Hague, human pregnancy is a struggle between the fetus and mother. Evolutionarily speaking, the fetus “wants” as many resources as possible for itself while the mother “wants” to do what she can to spread her resources across as many children as possible. In theory, this is a cause of the many serious health problems surrounding pregnancy.
Update: Carl Zimmer has more about this on his blog.

This is fascinating…”sex might have evolved as a way to concentrate lots of harmful mutations into individual organisms so they could be easily weeded out by natural selection”.
Kian and Remee are twin daughters born
Kian and Remee are twin daughters born to a UK couple…one is black and one is white. “If a sperm containing all-white genes fuses with a similar egg and a sperm coding for purely black skin fuses with a similar egg, two babies of dramatically different colours will be born. The odds of this happening are… a million to one.”

Justin reports on his family’s results of a neat project called the Geneographic Project, co-produced by National Geographic and IBM. If you purchase a testing kit, they’ll trace the specific genetic markers of your ancestors back to (possibly) our common African root.
Why do people believe in God? Evidence
Why do people believe in God? Evidence suggests that it’s partially inherited. “The degree of religiosity was not strongly related to the environment in which the twin was brought up. Even if one identical twin had been brought up in an atheist family and the other in a religious Catholic household, they would still tend to show the same kind of religious feelings, or lack of them.”
For some real controversy over evolution, check
For some real controversy over evolution, check out evo devo, or “evolutionary developmental biology”. Its proponents claim that evolution works primarily by changing when certain genes are expressed, not via changing genes themselves. Scientific American has more.
In the five years since the sequencing
In the five years since the sequencing of the human genome, “much of the data have little immediately useful meaning, and the research has produced only a trickle of medicine”. And where medical science has failed, hucksters have filled the gap.
Twenty percent of the human genome is
Twenty percent of the human genome is patented. I expect that someday in the future, my morning will be interrupted by a lawyer telling me that the company he represents holds a patent on the biochemical conversion of foodstuffs to energy suitable for powering a biological organism and that I should cease and desist eating my Cheerios.
Two of the biggest pessimists in the
Two of the biggest pessimists in the business, Bill Joy and Ray Kurzweil, outline their case for not releasing the genome for the 1918 influenza virus. “The genome is essentially the design of a weapon of mass destruction. No responsible scientist would advocate publishing precise designs for an atomic bomb, and in two ways revealing the sequence for the flu virus is even more dangerous.”
Flowers don’t smell as good as they
Flowers don’t smell as good as they used to and part of the reason is breeding…they’re breeding flowers for looks and longevity, not for scent. I believe Michael Pollan discusses this in his excellent The Botany of Desire (tulip chapter).
Scientists are having a bit of fun
Scientists are having a bit of fun wondering about the genetics of wizardry in Harry Potter. “This suggests that wizarding ability is inherited in a mendelian fashion, with the wizard allele (W) being recessive to the muggle allele (M). According to this hypothesis, all wizards and witches therefore have two copies of the wizard allele (WW).”
And, the rest of the (AIGA Conference) story
Here’s a sampling of the rest of the AIGA Design Conference, stuff that I haven’t covered yet and didn’t belong in a post of it’s own:
- Juan Enriquez gave what was probably my favorite talk about what’s going on in the world of genetics right now. I’ve heard him give a variation of this talk before (at PopTech, I think). He started off talking about coding systems and how when they get more efficient (in the way that the Romance languages are more efficient than Chinese languages), the more powerful they become in human hands. Binary is very powerful because you can encode text, images, video, etc. using just two symbols, 1 and 0. Segue to DNA, a four symbol language to make living organisms…obviously quite powerful in human hands.
- Enriquez: All life is imperfectly transmitted code. That’s what evolution is, and without the imperfections, there would be no life. The little differences over long periods of time are what’s important.
- Enriquez again: The mosquito is a flying hypodermic needle. That’s how it delivers malaria to humans. We could use that same capability for vaccinating cows against disease.
- Along with his list of 20 courses he didn’t take in design school, Michael Bierut offered some advice to young designers:
1. Design is the easy part.
2. Learn from your clients, bosses, collaborators, and colleagues.
3. Content is king.
4. Read. Read. Read.
5. Think first, then design.
6. Never forget how lucky you are. Enjoy yourself. - Nicholas Negroponte: If programmers got paid to remove code from sofware instead of writing new code, software would be a whole lot better.
- Negroponte also shared a story about outfitting the kids in a school in Cambodia with laptops; the kids’ first English word was “Google”, and from what Negroponte said, that was followed closely by “Skype”. He also said the children’s parents loved the laptops because at night, it was the brightest light in the house.
- Christi recorded Milton Glaser’s mother’s spaghetti recipe. “Cook until basically all of the water is evaporated. Mix in bottle of ketchup; HEINZ ketchup.”
- Ben Karlin and Paula Scher on the challenges of making America, The Book: Books are more daunting than doing TV because print allows for a much greater density of jokes. In trying to shoot the cover image, they found that bald eagles cannot be used live for marketing or advertising purposes. The solution? A golden eagle and Photoshop. And for a spread depicting all the Supreme Court Justices in the buff, they struggled — even with the Web — to find nude photos of older people until they found a Vermont nudist colony willing to send them photos because they were big fans of The Daily Show.
- Bill Strickland blew the doors off the conference with his account of the work he’s doing in “curing cancer” — his term for revitalizing violent and crime-ridden neighborhoods — in Pittsburgh. I can’t do justice to his talk, so two short anecdotes. Strickland said he realized that “poor people never have a nice day” so when he built his buildings in these poor black neighbohoods, he put nice fountains out front so that people coming into the building know that they’re entering a space where it’s possible to have a good day. Another time, a bigwig of some sort was visiting the center and asked Strickland about the flowers he saw everywhere. Flowers in the hood? How’d these get here? Strickland told him “you don’t need a task force or study group to buy flowers” and that he’d just got in his car, bought some flowers, brought them back, and set them around the place. His point in all this was creating a place where people feel less dissimilar to each other…black, white, rich, poor, everybody has a right to flowers and an education and to be treated with respect and to have a nice day. You start treating people like that, and surprise!, they thrive. Strickland’s inner city programs have produced Fulbright Scholars, Pulitzer Prize winners, and tons of college graduates.
- I caught 30 minutes of David Peters’ presentation of Typecast: The Art of the Typographic Film Title and realized I should have gotten there in time to see the whole thing. I could sit and watch cool movie titles all day long. Among the titles he showed were Bullit, Panic Room, Dr. Strangelove, Barbarella, The Island of Dr. Moreau, and Superman. The title sequence for Napoleon Dynamite (which was discussed on Design Observer last year) was shown later in the main hall.
- At the closing party at the Museum of Science, we checked out the cool Mathematica exhibit that was designed by Charles and Ray Eames, two designers who were also pretty big science/math nerds.
- And some final thoughts from others at the conference. Peter Merholz says that “form-makers”, which make up the vast majority of the AIGA audience, “are being passed by those who are attempting to use design to serve more strategic ends”. (That’s an interesting thought…) A pair of reviews from Speak Up: Bryony was a bit disappointed with the opening Design Gala but left, like everyone else, in love with emcee John Hockenberry while Armin noted that the preservation of digital files is a big concern for museums in building a collection of graphic design pieces…in 35 years, how are you going load that Quark file or run that Flash movie?

Lengthy examination of what makes people gay
Lengthy examination of what makes people gay by the Boston Globe. “What makes the case of [identical twins] Patrick and Thomas so fascinating is that it calls into question both of the dominant theories in the long-running debate over what makes people gay: nature or nurture, genes or learned behavior.”

A small ocean microbe called Pelagibacter has the smallest genome of any self-sufficient organism with 1,354 genes. It also doesn’t appear to have any extra DNA…no junk or redundant copies of genes.
The Red Delicious apple has fallen out
The Red Delicious apple has fallen out of favor. It’s been dumbed down too much for the market. For more on apples, see Michael Pollan’s excellent The Botany of Desire.
Male and female fire ants maintain their
Male and female fire ants maintain their own independent gene pools. “The sperm of the male ant appears to be able to destroy the female DNA within a fertilized egg, giving birth to a male that is a clone of its father. Meanwhile the female queens make clones of themselves to carry on the royal female line.”
Advancing scientific research means that chimeric animals
Advancing scientific research means that chimeric animals are on the way. “In the case of human cells’ invading the germ line, the chimeric animals might then carry human eggs and sperm, and in mating could therefore generate a fertilized human egg. Hardly anyone would desire to be conceived by a pair of mice.”
