Five new posts on key science findings at the Design of Life blog

Goodbye GATTACA: Environment and lifestyle affect which genes are actually expressed

The genes that matter are the ones that are expressed. A recent North Caroline State University study of North African Berbers showed that which breathing-related genes were expressed depended in large part on whether the individual is living an urban, rural, or nomadic lifestyle. Vince Freeman, the genetically troubled hero of GATTACA (1997), need not rely only on determination. He has other heavy hitters on his team too, as it turns out. Genes "R" Not Us.

Junk DNA - oops, non-coding DNA - less junky than ever but still expected to fit the "frame"

Junk DNA has sure come up in the world: From Dawkins's "sea of nonsense" to increasingly biologically important - but somehow it is still supposed to support the conventional explanations.

One consequence of growing efforts to "frame" science is that readers of reports on new research must be skilled at seeing past elaborate frames, in order to discern findings. For more, go here.

Cutting edge science: Cambrian explosion ecosystems organized themselves pretty much the way ecosystems do today, and not everyone is pleased to hear that ... (because it implies that there may be underlying patterns and laws within nature that are not merely incidental and mechanistic).

Natural selection: Mutation protects against malaria - at a steep cost. (A recent study supports Mike Behe's observation in Edge of Evolution that the protections against malaria that evolve through natural selection acting on random mutations (Darwin's mechanism) - apart from being few and far between - tend to come with serious problems. DON'T trust evolution to solve your problems!

Human evolution: Shape of early human teeth fails to predict actual diet, study finds.

"A recent study by anthropologist Peter Ungar of the University of Arkansas and colleagues has challenged the conventional way that anthropologists determine what early humans and human ancestors ate. Apparently, they didn't necessarily eat what they 'should have.'" So there is a lot we cannot predict about early human diets. For more, go here.

Toronto-based Canadian journalist Denyse O'Leary (www.designorchance.com) is the author of the multiple award-winning By Design or by Chance? (Augsburg Fortress 2004), an overview of the intelligent design controversy. She was named CBA Canada's Recommended Author of the Year in 2005 and is co-author, with Montreal neuroscientist Mario Beauregard, of the forthcoming The Spiritual Brain: A neuroscientist's case for the existence of the soul (Harper 2007).

  • ID The Future

    Intelligent Design The Future is a multiple contributor weblog whose participants include the nation's leading design scientists and theorists: biochemist Michael Behe, mathematician William Dembski, astronomer Guillermo Gonzalez, philosophers of science Stephen Meyer, and Jay Richards, philosopher of biology Paul Nelson, molecular biologist Jonathan Wells, and science writer Jonathan Witt. Posts will focus primarily on the intellectual issues at stake in the debate over intelligent design, rather than its implications for education or public policy.
