A Duck Has Fathered A Chicken (& Apparently This Is Just The Beginning)

A Duck Has Fathered A Chicken (& Apparently This Is Just The Beginning)

Because genetically modified food has been working out sooo well for everyone, scientists in Dubai decided to take their experiments a bit further. The Central Veterinary Research Labratory originally injected a duck’s DNA to produce eggs and sperm into a chicken hoping to make more fertile hens. But when the chicken produced duck sperm, the researchers decided to take things a bit further. Now, we have ducks fathering chickens, and it might not stop there. More »

Study Finds Depression, Autism and Other Psych Disorders Share Common Genetic Roots

Study Finds Depression, Autism and Other Psych Disorders Share Common Genetic Roots

What does schizophrenia have to do with depression? Or bipolar disorder with autism and ADHD? Sure, they’re all psychiatric disorders, broadly defined; but depression and bipolar are mood disorders, autism is considered a developmental disorder, ADHD a neurobehavioral problem and schizophrenia a good, old-fashioned “mental illness.” it sure shakes things up a little bit to note that all five mental health issues may stem from a common genetic variation.

Born Gay? Epigenetics Explains How People Could ‘Inherit’ Homosexuality

Born Gay? Epigenetics Explains How People Could 'Inherit' Homosexuality

The burgeoning field of epigenetics could explain the biological roots of people being gay, say researchers. Epigenetics looks at how genes are expressed and the temporary markers that control this expression, known as “epi-marks.” In a study published online Tuesday, scientists working with the National Institute for Mathematical and Biological Synthesis (NIMBioS) say sex-specific epi-marks passed from father to daughter or mother to son could cause homosexuality.

The Science Of A Six-Pack: Can Diet and Exercise Trump Genetics?

The Science Of A Six-Pack: Can Diet and Exercise Trump Genetics?

In October, we published “Starving For A Six-Pack“–a 3-part series chronicling writer Dana McMahan‘s experience prepping for and getting fitness model photos taken for her portfolio–and there was no shortage of controversy over the grueling diet she followed to get industry standard’s sculpted, toned look. Many argued that getting a six-pack (or muscle tone, in general) requires nothing more than “eating right” and working out. Others (including Dana) argued that a lot of what determines muscle tone is genetic; despite being strong and healthy, not all of us are destined for easily-sculpted abs. More »

Why You Should Care That Scientists Found 4 Types Of Breast Cancer

Why You Should Care That Scientists Found 4 Types Of Breast Cancer

New research identifying four major types of breast cancer has been getting a lot of attention from scientists (and reporters) hailing it as “the breast-cancer equivalent of putting a man or woman on the moon.” If you feel like you’re missing something, here’s a quick breakdown of why you should care about the new genetic research (and what it could do for our breasts).

Grossed Out By Meat? Blame This Stinky Pig Steroid (And Your Genes)

Grossed Out By Meat? Blame This Stinky Pig Steroid (And Your Genes)

Some people are white-knuckle vegetarians who fantasize about tender slices of warm, savory ham or crackling strips of bacon but, for whatever reason, resist the urge and stick with a meat-free diet. Others, though, are genuinely squicked out by the smell, the texture, and the appearance of animal products, making the choice an easy one. But it may not be due to a deep love for all animals, large and small; according to a new study by researchers at Duke University Medical Center, it may actually be that some people are grossed out by meat because of a genetic predisposition that makes them sensitive to steroids found in animal flesh. Are you one of them? More »

Faces of Meth™: Good Argument Against Drugs, Great Proof That Genes Aren’t Everything

Faces of Methâ„¢: Good Argument Against Drugs, Great Proof That Genes Aren't Everything

It’s not hard to prove that meth is a bad idea, but the Faces of Meth™ photos from Oregon’s Multnomah County Sheriff department definitely help the case. They’re also one of the most convincing arguments I’ve ever seen for the idea that we aren’t doomed to whatever our genes have in store for us: Proving that in the argument of nature vs. nurture, nurture can have an astounding—and sometimes catastrophic—effect.
