Scientists Have Observed Epigenetic Memories Being Passed Down For 14 Generations
Category: Science Alert
Original Article by Signe Dean appeared in Science Alert, April 27, 2019 The most important set of genetic instructions we all get comes from our DNA, passed down through generations. But the environment we live in can make genetic changes, too. Last year, researchers discovered that these kinds of environmental genetic changes can be passed down for a whopping 14 generations in an animal – the largest span ever observed in a creature, in this case being a dynasty of C.
Results of study involving primates suggest that speech and music may have shaped the human brain’s hearing circuits. In the eternal search for understanding what makes us human, scientists found that our brains are more sensitive to pitch, the harmonic sounds we hear when listening to music, than our evolutionary relative the macaque monkey. The study, funded in part by the National Institutes of Health, highlights the promise of Sound Health, a joint project between the
Harvard Medical School team leads pioneering gut-brain research Original article posted Oct 12, 2018 You are not alone — literally. And in a way, you are also not entirely 100 percent human — from a cellular perspective. According to the National Human Genome Research Institute, the human body is host to approximately 10 times as many non-human microbial cells to human cells [1]. There are 10-100 trillion microbiota (microbes) that live inside and outside the
Emergence of Hybrid Models of Genetic Testing Beyond Direct-to-Consumer or Traditional Labs
Category: JAMA
Original article from JAMA, May 30, 2019 Historically, genetic evaluation has been dominated by a clinician-centric traditional model in which a patient’s physician had the central responsibility for testing, such as ordering the test and communicating the results. Conversely, in the direct-to-consumer (DTC) model, consumers are more empowered because they can order their own tests, obtain samples using home test kits, and receive the results directly from the laboratory or company that provides the test.
9 Types of Manipulative Patients

Know their tactics and be prepared Original article from MedPage Today by Jeffrey E. Keller, MD May 23, 2019 One of the more common complaints that I hear from medical practitioners in jails and prisons (especially new practitioners) is, “These manipulative patients are driving me crazy!” Well, to be honest, I ran into a lot of manipulative patients when I worked in the ER, as well. But it is true that many of our patients in
