Will genetic research advances lead to a new era of racism?

At the same time, genetic information is slipping out of the laboratory and into everyday life, carrying with it the inescapable message that people of different races have different DNA. Ancestry tests tell customers what percentage of their genes are from Asia, Europe, Africa and the Americas. The heart-disease drug BiDil is marketed exclusively to African-Americans, who seem genetically predisposed to respond to it. Jews are offered prenatal tests for genetic disorders rarely found in other ethnic groups.

[…]

But many geneticists, wary of fueling discrimination and worried that speaking openly about race could endanger support for their research, are loath to discuss the social implications of their findings. Still, some acknowledge that as their data and methods are extended to nonmedical traits, the field is at what one leading researcher recently called ‘a very delicate time, and a dangerous time.’

‘There are clear differences between people of different continental ancestries,’ said Marcus W. Feldman, a professor of biological sciences at Stanford University. ‘It’s not there yet for things like I.Q., but I can see it coming. And it has the potential to spark a new era of racism if we do not start explaining it better.’

Stem Cells From Testes Produce Wide Range of Tissue Types

U.S. researchers say they’ve successfully reprogrammed adult stem cells from the testes of male mice into a wide variety of cell types, including functional blood vessels, contractile cardiac tissue, and brain cells.

If the same can be done with adult testes stem cells from humans, they may offer a source of new therapies to treat men with health problems such as heart disease, vascular diseases, diabetes, stroke, Parkinson’s, Alzheimer’s, and even cancer, the researchers said.

Ronald Bailey’s Singularity Summit coverage

By 2030, or by 2050 at the latest, will a super-smart artificial intelligence decide to keep humans around as pets? Will it instead choose to turn the entire Earth, including the messy organic bits like us, into computronium? Or is there a third alternative?

These were some of the questions pondered by the 600 or so technosavants meeting in the Palace of Fine Arts at the second annual Singularity Summit this past weekend. The meeting was convened by the Singularity Institute for Artificial Intelligence. The Institute’s chief goal is to make sure that whatever smarter-than-human artificial intelligence is eventually spawned by exponentially accelerating information technology that it will be friendly to humans.

Networks, Bacteria, and the Illusion of Control

Brainsturbator stitches together a number of articles, some of which you may have seen here, to make the case that we’re less in control of our minds and bodies than we think.

Baring Your Genes in Public–A Full Individual Human Genome Sequenced for the First Time

Would you want to know your genetic predisposition to alcoholism, coronary artery disease, obesity, Alzheimer’s disease, antisocial behavior and conduct disorder? Genome pioneer Craig Venter now does and he is revealing to the whole world that he’s got genes that make him more susceptible to them all. Venter and his team have for the first time sequenced a full (diploid) set of human chromosomes–his.

Do We Need to Regulate Dead Men’s Sperm?

Caplan also notes that children have been born using sperm taken from the still warm bodies of men who died unexpectedly. With the advent of egg freezing, dead women may also be able to become posthumous parents in the future.

But why do we need regulation in this area? Have there been abuses? If so, Caplan cites none in his column. Men who freeze sperm might be presumed to want children and in fact, most of them have probably left written instructions on what do with their reproductive remains. If a man hasn’t left any explicit instructions, the decision should be left up to the next of kin–wives or parents. The same thing goes for for taking sperm from men who suddenly drop dead.

Russia bans human tissue export in bioweapon alert

Russia has banned the shipment of medical specimens abroad, threatening hundreds of patients and complicating drug trials by major companies, the national Kommersant newspaper reported on Wednesday.

Kommersant attributed the ban to fears in the secret service that Russian genetic material could be used abroad to make biochemical weapons targeting Russians. The quality daily cited anonymous sources in the medical community.

Morbid environmental question: what’s the most ecologically sound way to dispose of a dead body?

A few months ago Honky Tonk Dragon asked me what I want done with my remains if I were to perish. I thought about it and wasn’t too sure, saying “whatever is the most ecologically friendly method.” I’ve been thinking about it again, and the only thing i could find on the subject is this article which suggests that feeding the dead to animals is the best way to go. I’m not really sure how one would arrange for such a thing, but I’d be fine with that.

Are there any other methods out there?

In a first, scientists develop tiny implantable biocomputers Discussion at PhysOrgForum

Researchers at Harvard University and Princeton University have made a crucial step toward building biological computers, tiny implantable devices that can monitor the activities and characteristics of human cells. The information provided by these “molecular doctors,” constructed entirely of DNA, RNA, and proteins, could eventually revolutionize medicine by directing therapies only to diseased cells or tissues.

Third ear open

stelarc third ear

Earlier this year, Stelarc finally found a medical doctor willing to implant a cell-cultivated ear beneath the skin on the artist’s forearm.

[…]

Stelarc is apparently planning to go through a few more surgeries to give it more definition.

“He’s also going to implant a mic inside the ear that will connect to a bluetooth transmitter, so the ear can broadcast audio from the internet wirelessly,” explains former BB guestblogger and sometimes Stelarc collaborator Karen Marcelo. “That Stelarc, always got something up his sleeve! He likes to say that too. ”
