What Baby Teeth may Tell Researchers About Autism

Researchers are constantly studying and learning more about autism spectrum disorder (ASD), but they have yet to be able to pinpoint specific causes. The origins of the disorder seem to be based in genetics and environmental factors. Now a study funded by the National Institute of Environmental Health and Sciences (NIEHS) seems to suggest that exposure to heavy metals could be one of the environmental triggers of autism. [1]

The Untragic Mulatto

I remember, vividly, on a certain Martin Luther King Jr Day during my childhood—back before schools regularly observed the federal holiday—when my kindergarten teacher passed out coloring pages of Dr. King’s portrait which the class was to fill in. Not a minute after I began coloring brother Martin’s face the same color as my Afro-Filipino father—brown—I noticed all but two or three of my white classmates were coloring the page with black crayons.

Roderick Kaine - Smart and SeXy: Biological Differences Between Men and Women - Hour 1

Roderick Kaine is an American who has a degree in biochemistry, and he has done professional research in both Biology and Neuroscience. After moving on from this work, he has focused on writing and independent scholarship. Around 2010, Roderick began his work on his book, Smart and SeXy, which describes the biologically based cognitive differences between the sexes by using the latest research in neuroscience and genetics. Smart and SeXy was published in 2016. He has been active in the neoreactionary movement since 2014, where he writes under the name Atavisionary.

First Human Injected with Controversial Genetically Modified Genes

For the first time in history, a human has been injected with genes edited using the CRISPR-Cas9 method. [1]
The experiment took place on 28 October 2016, when a team of Chinese scientists, led by oncologist Lu You at Sichuan University in Chengdu, delivered the genetically modified (GM) cells into a patient with aggressive lung cancer as part of a clinical trial at the West China Hospital in Chengdu. [2]
To protect the patient’s privacy, the details of the trial have not been released; but Lu said the trial “went smoothly.”

Smoking can Permanently Damage DNA – But Quitting can Heal Some Wounds

A new study published in the American Heart Association (AMA) journal Circulation: Cardiovascular Genetics finds that smoking cigarettes affects the human genome in the form of DNA methylation. [1]
If you quit smoking, the majority of the damage goes away, but not all of it. Translation: smoking causes some permanent damage.
