Brown out!

The most common emails I receive are about hair and eye color, and of these the most frequent source seems to be from individuals in interracial relationships. Quite often they are curious as to the possible outcome of their offspring’s phenotype. Sometimes they wonder why their offspring looks the way he or she does. On…

The genomic future is almost here?

Technology dramatically speeds gene mapping. A short little piece which repeats the standard mantras; faster, cheaper and better. The Human Genome Project was proof of principle. Right now, with all the stuff that is starting to bubble up around personal genomics it looks like we’re at a technological and social point of no return, the…

Sidr hearsay blogging

Just talked to my mother today and she phoned relatives in Dhaka. Everything is OK, electricity is coming back online. She seemed dismissive of the idea when I asked if it was all well in the rural areas where some of my distant relatives live; it wasn’t that big of a deal. On the other…

Glimpse of the future?

My Genome, Myself: Seeking Clues in DNA: For as little as $1,000 and a saliva sample, customers will be able to learn what is known so far about how the billions of bits in their biological code shape who they are. Three companies have already announced plans to market such services, one yesterday. Offered the…

Sidr update

Update: OK, not to be morbid, but the confirmed death tolls is now greater than 3,000, and there is a tentative projected death toll on the order of 10,000. That’s in line with my comments below. End Update The death toll is pushing 2,000. I think I might be safe in saying that the fatalities…

Questioning the breastfeeding & IQ link

A few weeks ago I reported some research that seemed to show a relationship between a gain in IQ due to breastfeeding and a particular genetic variant. Looks like I spoke too soon. p-ter has the goods: The fact that they have a measure of maternal IQ but don’t directly include it in the published…

The evolving male

Simpler mode of inheritance of transcriptional variation in male Drosophila melanogaster: Sexual selection drives faster evolution in males. The X chromosome is potentially an important target for sexual selection, because hemizygosity in males permits accumulation of alleles, causing tradeoffs in fitness between sexes. Hemizygosity of the X could cause fundamentally different modes of inheritance between…

Is Sidr a sign of progress?

It’s almost Friday here in the United States. The latest update I can find is that 200 people have died due to typhoon Sidr. These are almost certainly “early returns,” and the numbers will keep going up. Like pre-modern battles most of the fatalities won’t be directly due to the cyclone. Social disturbances, and likely…

Radio Open Source almost back?

Read about it.
