Epigenetics has become a hot topic in biology. There are players "above DNA"– some heritable – that may be more important than the genetic code itself.
Within the factories of molecular machines that run living cells, including those in the human body, processes occur non-stop that are designed to meet every contingency. Here are just a few examples.
As scientists continue to find incredible diversity in the smallest of organisms, realizations of all we've been missing are changing conceptions of life.
The race continues between scientists desperately seeking a rationale for harvesting human embryos and those who say, having adult stem cells and iPS cells available, they are unnecessary – and their use is unethical.
News sites are celebrating a "spectacular" new record for fossil DNA, claiming horse genes found in permafrost are 700,000 years old, placing the common ancestor two million years earlier than thought.
An intelligent design advocate is publishing a book this month that uses the Cambrian Explosion as evidence against Darwinism and for I.D. Two major evolutionary paleontologists have also published a book about the issue.
If you thought work on human cloning and embryonic stem cell research went out of style with the discovery of induced pluripotent stem cells, watch out. The pro-cloning people, who never lost their lust for toying with human embryos, are back.
How does a growing flower bud or feather follicle know where to put the intricate colors and patterns on a mature flower or feather? Scientists are beginning to get partial answers.
