(Phys.org)—Raising the temperature is one easy way to get chemical reactions to speed up. This temperature dependence can be accurately described by a simple exponential relation known as the Arrhenius equation. A commonly ...
For more than a century, scientists have understood the basics of inheritance: if good genes help parents survive and reproduce, the parents pass those genes along to their offspring. And yet, recent research has shown that ...
