Compare the DNA of two people and you see about three million base sequence differences and compare the DNA of a human and chimp and you see about thirty million. This is out of about three billion bases total. So, at the DNA level, people are about 99.9% identical to each other and about 99% … Read moreWhy are people different from chimps??

Last Tuesday in Mississippi the “personhood amendment” garnered only about 42 percent of votes and (fortunately) did not pass. This proposed amendment to the State Constitution stated, “life of an individual begins at fertilization, cloning, or the functional equivalent thereof”. We wish to comment that this interpretation should raise serious doubts and concerns. The proposed … Read moreMississippi says no to Personhood amendment
We got her about twelve years ago, as a little fluff of fur puppy that was happy as a lark, jumping around and into endless mischief. What a joy to be around. She grew up quickly to a medium-sized dog, but still full of energy, and happy to run around in big circles in our … Read moreI miss my dog
Benjamin Franklin wrote in 1789, “The only things certain in life are death and taxes.” Well, for the last couple of years General Electric has shown that it is possible to make billions and pay no taxes. And some recent startling advances in aging research suggest that Ben might have been wrong on both counts. … Read moreAnother important step towards a cure for aging
Eggs and sperm are pretty special cells. They are the chains that link one generation to the next. In a sense they are our immortal parts, with some living on in our children, and some of theirs carrying on in yet the following generation, and so on. The scientists that study these cells consider them … Read moreTurning skin into sperm
Historians might refer to our current era as the Age of DNA Sequencing. There is an incredible technological revolution going on that is radically reducing the cost of DNA sequencing. The Human Genome Project, which determined the first complete Human DNA sequence, was completed about a decade ago, at a cost of over three billion … Read moreThe DNA sequencing revolution and our designer genes future
In many ways our DNA defines us. Consider identical twins, which are the result of an embryo splitting in early life. They are actually a single individual that divided into two parts during the early stages of embryonic development. They don’t call them identical for nothing. Studies show that in addition to looking the same … Read moreDNA Proves Evolution
I recently blogged on a visit to the creation science museum, located not far from my home in Cincinnati, Ohio. It is a creationist alternative to natural history museums. The creation museum attempts to provide scientific authenticity and respectability to the creationist view that the bible is literally true in every detail. That is, God … Read moreA fresh look at the Creation “Science” Museum
There is a quiet revolution going on in the world of cloning. Very few have heard of it, but its potential power is astonishing. Imagine a radical new way to clone that can not only create exact carbon copies of adults, but also allows the generation of important genetic improvements. Another you, but smarter, healthier, … Read moreRadical Cloning
