Study: Gays made via epigenetics, not genetics

“Epigenetics – how gene expression is regulated by temporary switches, called epi-marks – appears to be a critical and overlooked factor contributing to the long-standing puzzle of why homosexuality occurs.” [EurekAlert]

Passing on an eating disorder

Claire Vickery was not surprised when scientists announced that eating disorders have a genetic link, because she and her two daughters suffered from the illness.

Hmm… I wonder how strong these epigenetic effects are when the offspring are raised in a different environment. Continue reading

How your great grandmother’s chemical exposures may affect you

Ovarian diseases that persist across three generations develop in rats exposed to common environmental chemicals at a key time before birth. Continue reading

New “evidence” for flame retardant’s role in autism

For the first time, scientists have reported that the environment and genetics can work together to create autism-like symptoms in mice exposed in the womb to a flame retardant. The female mice — born to mothers that are genetically more susceptible to develop autistic behaviors — were less social and had impaired memories and learning skills after their mothers were exposed to a brominated compound known as a PBDE.Continue reading

Researcher: Exposure to toxins can alter DNA

Women with ovarian disease may have inherited it from great grandmothers who were exposed to toxic chemicals decades ago, according to a study by Washington State University researchers.

Uh-huh… they may have been overflown by black helicopters, too. Continue reading

Whoa! Really big stretch: WWII Chemical Exposure Spurs Obesity, Autism, Researcher Says

The World War II generation may have passed down to their grandchildren the effects of chemical exposure in the 1940s, possibly explaining current rates of obesity, autism and mental illness, according to one researcher. Continue reading

Environmental toxicants causing ovarian disease across generations

WSU researchers expand research on environmental epigenetics and ovarian disease Continue reading

Lamarckism Returns: ‘Epigenegtics the next big thing’

Alarmist researchers would like to use neo-Lamarckism to scare people about politically incorrect exposures causing hereditable harms. Continue reading

Claim: Study shows how high-fat diets increase colon cancer risk

Except there’s no reason to think that diet affects colon cancer risk. Continue reading

NS: Fossil DNA has clues to surviving rapid climate change

Well, actually one of six samples exhibited methylation, something which has been found once before. Proof of broad inheritance? No. Continue reading

Revenge of Lamarck: New study casts doubt on Mendelian genetics?

Epigenetics is the new frontier in junk science-based health and environment scares. You read it here first. Continue reading
