Redefining genetic privacy
Experts discuss how advances in genetics will require a rethink about privacy. How do we protect it and would we forgo it over improved health?
This article is an interesting insight into how advances in genetics will likely require a rethink about privacy and how we protect it.
It reports on a meeting at the recent 2010 AAAS conference in San Diego. There a panel of experts criticized US policies and offered solutions to the ethical issues associated with how DNA can or might be used to identify characteristics about us we might want to keep private. It is based on the US legal system, but the same issues would be applicable in Australia.
Australian discussions
I have come across a few people that for differing reasons have no issues with people knowing intimate stuff about them. See TechNyou blog, Cheap Genetic test
Most people I chat to about this, however, do have concerns, but are also torn by the fact that such knowledge could help understand a lot more about human disease and how to treat or prevent it in the first place. If there was to be a choice, not that there needs to be such a stark choice, many of these people would opt for better health over privacy. That is, they would be willing to forgo some of their privacy if it meant better health care for them.
Some of the comments are interesting as well.

Stem Cells Restore Sight in Mouse Model
Mouse embryonic stem cells have been used to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa.

Nano zinc in sunscreen. It gets in – apparently?
Apparently the nano zinc in sunscreens is getting into our bodies and who knows what it can do to us. At least that would be a reasonable conclusion to draw if you read The Australian today (25 Feb 2010, page 5)
The article
Following is the headline and first couple of paragraphs from the article:
Sunscreen’s zinc factor ends up in blood
PEOPLE who use a lot of sunscreen could be at risk of having “larger than normal” quantities of zinc in their bloodstream, with new evidence showing zinc particles penetrate the skin and are absorbed into the body.
Geochemist Brian Gulson, of Sydney’s Macquarie University, has provided the first conclusive evidence that zinc oxide nanoparticles – which appear in many translucent sunscreens – can be absorbed by the body and remain there for extended periods of time.
The horse’s mouth
Being the skeptic-type that I am I thought this was a bit extreme based on what I knew already about Professor Brian Gulson and CSIRO’s research into this. So I went to the horse and got it from his mouth – Prof Brian Gulson, that is.
Here is what Prof Gulson had to say:
“We have not found that ‘zinc oxide nanoparticles can be absorbed by the body”
“Our study has shown that zinc from sunscreen can reach the blood in small amounts. We have not found any difference between conventional zinc oxide sunscreens and nanoparticle sunscreens and we don’t know what form the zinc is in.”
“It is also worth noting that in our study the increase in zinc we saw in blood was about one thousandth of the normal levels of zinc in blood.”
My mother always said, don’t believe what you read in the papers.

Nanotech to enable a computer memory a million times faster
A forest of erect nanowires will form the basis of computer memory that will be a million times faster, an IBM physicist said at this week’s ICONN conference in Sydney.

Human enhancement: are we going cyborg. Slide show
Selected slides from secondary teacher workshop titled, Human enhancement: are we going cyborg
Last Friday I ran a workshop at the VCE biology conference in Melbourne titled Human enhancement: are we going cyborg. A number of teacher expressed interest in obtaining the slides I used. So here they are. I have uploaded them to Slideshare as well. It has inspired me to upload a few other relevant workshops, so keep checking or look up TechNyou on Slideshare
