Maternal health during gestation and prenatal conditions are well documented as having profound effects on health and development of a baby after birth. The mechanisms behind many of these effects are attributed to epigenetic changes that take place in utero. More recently, pre-fertilization maternal health has been also been implicated in affecting development of babies ...The post Yet Another Reason to Thank Dad This Father’s Day! Evidence for Paternally-Inherited Epigenetic Modifications

The second day of the American Scientific Summit kicked off a bit early, especially for those of us who stayed up late to enjoy the excellent food and entertainment on Bourbon Street. The two themes of the morning were the changing landscape of medical genetics, and microbial detection and epigenetics.
First up was Richard Gibbs from the Baylor College of Medicine Human Genome Sequencing Center on the realities of clinical sequencing. He started off talking about predictability of future events

Great Minds - Goodall, Fossey & Galdikas
Today we know that humans and chimpanzees share 99% of their DNA and that we have a lot in common. Not just how we look, but how we behave, form groups, defend our turf, and love each other. People didn’t always see other primates this way, but in the 1960s and ’70s, some amazing intrepid women came along to turn primatology on its hairy head. Jane Goodall, Dian Fossey and Birute Galdikas studied chimpanzees, gorillas and orangutans,
The Scientific Secret of Strength and Muscle Growth
It turns out that superhuman strength may not be so farfetched! After losing the Myostatin producing gene, many animals (including humans) increase muscle mass drastically.

Breast cancer, iPads, the Supreme Court's gene patent decision and more in this week's double edition of LabBook.
While the forensic and general communities continue to argue about the merits of the recent Supreme Court ruling on collection of samples from arrestees prior to conviction, I am fascinated by the technology that make this question relevant. The conventional way of generating a DNA profile from a sample by STR (short tandem repeat) analysis […]

The horses bear a striking resemblance to those depicted in European cave paintings with short necks, spiky manes and a yellow hue.
As a bone-a-fide dog lover, it gives me great pleasure to highlight Baynes and Agassiz Fuertes' beautifully illustrated "The Book of Dogs: an intimate study of mankind's best friend" as this week's book of the week. In it, the famous ornithologist and illustrator lends his hand to the descriptions and art of drawing various breeds of "man's best friend" while Baynes tells stories of dog fame, adventure, and heroism, such as this one about Red Cross dogs in WWI:pg. 55"The Red Cross dogs
PS4B - Electromagnetic Radiation
In this video Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. A number of phenomenon (including refraction, emission spectrums, and gamma radiation) are discussed. A teaching progression K-12 is also included.
