Don't extinct, excel!

I recently got into a discussion with some people on Facebook. A friend had posted a link about the impact of humans on the environment and some of his friends mentioned being supporters of the Voluntary Human Extinction Movement. I couldn't keep quiet even though I generally know better than to argue with extremists on the internet. To my mind, anyone who advocates human extinction is depressed and suicidal on a species-wide scale and needs some mental health care. Obviously, I do realise humans haven't been taking very good care of their environment, but to extinct us just isn't normal and natural behaviour. The VHEM has a lot of arguments for their case on their website, and a lot of them are fallacious or at best one-sided half-truths. My two main arguments in favour of the presence of the human race on this planet are featured as well.

Regeneration and rejuvenation: science fiction... right?

Having just watched Susan Lim and Anthony Atala talk on TEDMED, I'm amazed at what modern science can already do. They can take adult stem cells and turn them back into fully versatile stem cells - similar to embryonic stem cells but without the ethical dilemmas - and use them to regrow broken organs in the body. Another option is to take working cells from the bit of body you need to repair and grow more of them in a Petri dish. Then you take the cells, put them on a 'scaffold' and grow a whole new organ. There's actually someone out there who has a working bladder grown in a lab from her own bladder cells more than a decade ago.

I wonder if this would work for pituitary glands, and other glands in the body? The current research seems to focus on kidneys and livers because that's what the majority of people on the waiting lists for donor organs are waiting for. Are pituitaries more complex than kidneys and livers, or similar?

I imagined a cyborg solution to the problem of broken pituitaries, using nanotechnology. It seems the cell biology approach is the more likely candidate for success.

Robots are your friend

When TED tweeted this video of a TED talk by Cynthia Breazeal about robots I knew this would be something I was going to blog about. Some of the first science fiction I ever read was Asimov and I've always felt particularly attracted to his I, Robot stories. Ever since childhood, I expected flying cars and robots, not to mention space colonization to be a part of my future. I'm still waiting. But I needn't be all that disappointed, because the development of robots is further along than I thought! I might not be able to get a dependable robot nanny for my children, but perhaps there will be one for my grandchildren, or maybe a lovely 24/7 robot carer in my old age.

How to survive a zombie apocalypse... with Addison's

Like most sci-fi geeks, we have worked out a fairly detailed plan of action in case of zombie apocalypse, or possibly a more conventional sort of apocalypse such as a meteor strike or the collapse of civilisation. Or should I say, we had worked out a good plan. Post-apocalyptic survival becomes a lot more complicated when you have a dependency on life-sustaining medication. Not only do we have to worry about food, water, fuel and ammunition, we need to be sitting on top of a well stocked hospital pharmacy as well.

Any other tips?
