Are you at-risk for Alzheimer's? Are you predisposed to Parkinson's? Do you have an increased chance of cancer? A new breakthrough in science lets you...
Why are some people so quick to latch on to bold claims about the biological origins of homosexuality? I think it's because they believe that we need to show that we're born gay in order to establish that our sexuality is a deep, important and relatively fixed part of who we are.
I've always believed that when you pray for God's will, you are praying simply for the strength and wisdom to choose what God would want you to choose. In other words, you aren't praying for God to intervene in this world. You're praying to enable yourself to do what God would have you do.
Will you wait for your own crisis, however it presents itself, or will you open your eyes and your heart, learn from the experience of others, and make changes now to embrace your authentic self?
Reductionism has its limitations. Is a human being -- one who bristles at injustice, weeps at Pachelbel's Canon, loves her children, is awestruck by beauty, and craves chocolate -- simply the product of Pavlov's conditioned reflexes to stimuli?
Only by knowing Mik-tal's endowment to us can we hope to meet the challenges of the modern world. Our efforts to find our way home begin by knowing where home is, and where we are now. Our efforts to achieve dietary health begin by knowing ourselves.
Welcome again to my blog, Toxic Tracks. Please send along any feedback or ideas for environmental health topics via email or Twitter. Among its devas...
To see where the clash comes from, we first need to understand the revolutionary nature of the Imago Dei idea in its original context in the texts of Genesis.
Using experimental systems where male rats can self-administer cocaine, researchers found that the sons of the cocaine-using fathers were resistant to the allure of cocaine. These results seem counterintuitive from a scientific viewpoint.
In a Tacoma holding pattern, waiting for Lee's return from sailing across the Pacific, I continued seeking out American heroes who are making changes in food quality.
While it's profoundly difficult predicting the developmental trajectory of any single individual, new research suggests we can influence the odds that people will retreat within themselves or unleash the fundamentally human drive to explore and create.
The idea is that when the epi-marks on genes that affect sexual orientation get passed from father to daughter, then some traits end up more masculinized. Likewise, mother-son transmission of epi-marks can result in the feminization of some traits.
What we want to discuss here is the effect of endocrine-disrupting chemicals (EDCs) on evolution and show how present evolutionary theory, developed and codified prior to the chemical revolution, does not account for life in our contaminated world.
Molecular analysis of genome regulation and change have uncovered additional pathways for ecological input into the evolutionary process.
McClintock predicted that we would focus on how the genome responds to challenge. Clearly, unraveling the molecular basis of epigenetic regulation is an integral part of that revolutionary research agenda.
This is number two in my series on epigenetic control of genome restructuring and hereditary transmission of traits modified by life history events. We are going to take a detour through some classic bacterial genetics history, but it will ultimately bring us back, with new insights, to epigenetic regulation.
Two postings back, I promised a commenter called Sierkovitz that I would discuss epigenetics. This is an important subject with major implications for understanding natural genetic engineering in evolution.
For many years it was thought that our genes were the whole game -- the stuff that determined our appearance, our aptitudes, and even our susceptibility to disease. But we now know it's more complicated than that. It turns out that not all of our genes are active. Some are turned "on" and others are turned "off."
While most population biology is highly theoretical and conjectural, the Grants have been following what has actually been going on in the wild. Theirs is an exciting scientific and human story, including raising and educating their daughters in a tent while making field observations.
We haven't proved that chemical exposure is at the root of increases in mental health disorders. What we do know with increasing confidence, however, is that chemical exposure is changing our brains, and that those changes are being passed on to our descendants.
How could natural selection operate so that "the good ones spread in the population" if there were no positive variants in the first place? That is why I am confounded by Jerry Coyne's comment that he can explain natural genetic engineering by "garden variety natural selection."
The environment in which your great-great-grandmother lived, breathed, ate and drank might be responsible for health problems endured by you, your chi...
We all know that regular exercise can boost cardiovascular health and help you to maintain a healthy weight. But even for the most health-conscious am...
It turns out that you aren't just what you eat -- you're also "what you do," according to Juleen Zierath, professor of clinical integrative physiology...
David Code would like us to all calm down. NOW. It is urgent he says, even while understanding that urgency itself is a cause of stress, because it's ...
