Temperature dependence and the thermal limits of embryogenesis
(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 ...
New mechanism of inheritance could advance study of evolution, disease treatment
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 ...

Imperfect system is all that protects you from genetic parasites out to destroy your genes
We like to think of evolution as a fine-tuning process, one that whittles away genetic redundancies. The only problem is, we are not fine-tuned machines. Our bodies are chock-full of parts that either don't work anymore or ...
