Powerful new genetic tools allow scientists to alter the DNA of any organism—with tests on human embryos already underway. Even more ambitious, synthetic biologists on the verge of creating the genetic material for a living organism from scratch are setting their long-term sites on fashioning a fully synthetic human genome.

The inflationary theory of cosmology, an enduring theory about our universe and how it was formed, explains that just after the Big Bang, the universe went through a period of rapid expansion. This theory has been critical to understanding what’s going on in the cosmos today.
