Scientists Discover Parts of Our Bodies Age at Different Rates

Some people age faster than others, but the discovery of a DNA body clock by UCLA researchers now shows that different parts of our bodies age faster than others. The discovery offers important insights into the aging process — and what we might be able to do about it. » 10/21/13 8:13am 10/21/13 8:13am

How an 1836 Famine Altered the Genes of Children Born Decades Later

Why do some identical twins look so different from each other? Could your eating habits during puberty have an impact on the genetic makeup of your grandkids? These are just two of the startling questions raised by the science of epigenetics, as this "deleted" chapter from David Epstein's book The Sports Gene explains. » 8/26/13 8:00am 8/26/13 8:00am

Is it really true that homosexuality can be explained by epigenetics?

Early last week we told you about a new paper published in the Quarterly Review of Biology which suggests that homosexuality arises on account of epigenetic processes rather than genetic ones (i.e. non-heritable factors that alter the expression of DNA). Not surprisingly, the web exploded in a firestorm of debate,… » 12/20/12 2:30pm 12/20/12 2:30pm

Scientists claim that homosexuality is not genetic — but it arises in…

A team of international researchers has completed a study that suggests we will probably never find a ‘gay gene.' Sexual orientation is not about genetics, say the researchers, it's about epigenetics. This is the process where DNA expression is influenced by any number of external factors in the environment. And in… » 12/11/12 8:00am 12/11/12 8:00am

Working out during pregnancy could boost your baby's brain defenses

Buff moms make for healthy babies.

Use epigenetics to place a long-lasting curse on your enemy's family

There was once a time when witches could place a curse not only on their enemy, but on their enemy's sons and daughters, stretching on into eternity. Then came the era of science, when what happened to people was a combination of chance, determination, and genetics, and no family curses could touch the young. But now, … » 7/27/11 9:00am 7/27/11 9:00am
