I’ve been getting a lot of questions about when I’ll be able to share the video of my debate on the existence of God at Virginia Tech back in March. I’ve been in touch with one of the organizers for the debate and as of two weeks ago the VT Video Productions was almost finished with the final video. I’ve been anxiously checking the mail every day for a while now so I’m looking forward to getting it just as much as several of you. Once I get it I’ll let you know and I’ll share it. I’m really hoping it’s this week.

Evolution Seen in ‘Synthetic DNA’
Original post by BBC Science & Technology.
Researchers have succeeded in mimicking the chemistry of life in synthetic versions of DNA and RNA molecules. The work shows that DNA and its chemical cousin RNA are not unique in their ability to encode information and to pass it on through heredity. The work, reported in Science, is promising for future “synthetic biology” and biotechnology efforts. It also hints at the idea that if life exists elsewhere, it could be bound by evolution but not by similar chemistry.
In fact, one reason to mimic the functions of DNA and RNA – which helps cells to manufacture proteins – is to determine how they came about at the dawn of life on Earth; many scientists believe that RNA arose first but was preceded by a simpler molecule that performed the same function.
However, it has remained unclear if any other molecule can participate in the same unzipping and copying processes that give DNA and RNA their ability to pass on the information they carry in the sequences of their nucleobases – the five chemical group “letters” from which the the two molecules’ genetic information is composed.
