Game Changing Wearable Technology
Imagine a wearable computing device that will project a Minority Report user-interface on any surface. A few more levels deeper and we’ll have wearable technology akin to Vernor Vinge’s Rainbow’s End, which I think is completely possible within our lifetimes, and most definitely possible within our children’s lifetimes.
One more level after this, we’re talking Ghost in the Shell level of human/computer integration.

“Junk DNA” Re-Awakened to Fight HIV
What? We (humans) have had the potential ability to naturally resist HIV-1? Well, golley-gee, Toto, let me click my heels and decry, “There’s no place like our genomes! There’s no place like our genomes!”
In all seriousness, this is a huge breakthrough and something to keep an eye on:
A group of scientists led by Nitya Venkataraman and Alexander Colewhether wanted to try a new approach to fighting HIV – one that worked with the body’s own immune system. They knew Old World monkeys had a built-in immunity to HIV: a protein called retrocyclin, which can prevent HIV from entering cell walls and starting an infection. So they began poring over the human genome, looking to see if humans had a latent gene that could manufacture retrocyclin too. It turned out that we did, but a "nonsense mutation" in the gene had turned it off at some point in our evolutionary history.
…
The human cells made retrocyclin, fended off HIV, and effectively became AIDS-resistant. And it was done entirely using the latent potential in the so-called junk DNA of the human genome.
For the more scientific-minded, here’s a more technical article. For the rest, here’s a summary.
