Everything evolves. Plant and animal species adapt to their environments. Rocks, under heat or pressure, shift form. Earth revolves around a sun that traces its arc of existence through the ever changing cosmos. And with this issue, Scientific American introduces the latest design and content adjustments in its 165-year history, ready to embrace the next 165.

Longtime readers will see much that is familiar in the magazine and its Web site, www.ScientificAmerican.com, from the classic design to the hallmark informational graphics. As always, collaborations with scientists—as authors of the feature articles and as sources for top journalists—inform everything we do.

You made it clear that the feature articles are important to your relationship with Scientific American. You want to dive deep into the science in some articles but also enjoy some shorter pieces. You want a variety of topics, from basic research to technologies, from physical sciences to life sciences. This issue delivers: in our cover story, biologist Jonathan K. Pritchard tells us “How We Are Evolving.” Physicists Stephen Hawking and Leonard Mlodinow describe “The (Elusive) Theory of Everything.” Other articles look at the wonder of an octopus sucker, the challenge of designing ethical robots, the true value of the Human Genome Project, the tribulations of parents with autistic children and the production of fuels using “artificial photosynthesis.
