by Tony Trueman, European Sociological Association Genealogical research and genetic testing are revealing skeletons in family closets and causing rifts among members, a new study shows. Family members have discovered they are unrelated or have relatives from an unexpected ethnic group, the research says. Katy Barbier-Greenland and Associate Professor Deborah Dempsey of Swinburne University, Australia,...

Moles on the body largely influenced by genetics, finds new study
KING’S COLLEGE LONDON A study published this week in the journal Pigment Cell & Melanoma Research has found that genes have a greater influence than previously thought not only on the number of moles you have but also where they are on your body. Survival of skin cancer is known to be influenced by gender, with female patients demonstrating higher rates of survival linked...

Genetic characteristics of peripheral artery disease
by Matt Batcheldor, Vanderbilt University Peripheral artery disease (PAD)—a narrowing of the arteries serving the legs and feet —affects as many as 12 million Americans and 200 million people worldwide. It is a manifestation of clogged arteries, but until now, scientists lacked information about why some people with the disease presented with problems with their...

Autism Is Largely Genetics Than Environmental, New Study Finds
By Rubi Valdez Tech Times A new study finds evidence proving that autism spectrum disorder or ASD is largely due to genetics, not environmental, discrediting claims that it is vaccine-related. The largest study of its kind involving more than 2 million people from five countries showed that ASD risk if 80 percent reliant on genes. The...

Turbo chip for drug development
by Karlsruhe Institute of Technology In spite of increasing demand, the number of newly developed drugs decreased continuously in the past decades. The search for new active substances, their production, characterization, and screening for biological effectiveness are very complex and costly. One of the reasons is that all three steps have been carried out separately so...

Genetics may help predict the right blood pressure drug for you
Medication can play a huge role in reducing high blood pressure, a leading cause of stroke, heart attack and other serious health problems. Yet given the wide selection of drugs for doctors to choose from, figuring out which drug works best for someone is difficult. But researchers may have found a better way to predict the effectiveness and side...

New method to detect off-target effects of CRISPR
by Julie Langelier, Gladstone Institutes Since the CRISPR genome editing technology was invented in 2012, it has shown great promise to treat a number of intractable diseases. However, scientists have struggled to identify potential off-target effects in therapeutically relevant cell types, which remains the main barrier to moving therapies to the clinic. Now, a group of scientists at the Gladstone Institutes...

The Prospects of Behavioral Genetics: Bad Genes Behind Crimes, Precision Education And Loosing Free Will?
Can the “warrior gene” explain aggressive and violent acts so that lawyers base their defenses on that in courts? Can genetics determine whether your marriage will be a long-lasting companionship? What about alcoholism, depression or autism? To what extent are we the product of our environment or the expression of our genes? While the nature versus nurture debate has been...

Blocking protein’s activity restores cognition in old mice, study shows
by Stanford University Medical Center By blocking a protein’s activity with antibodies, Stanford University School of Medicine investigators were able to improve cognitive behavior in aging mice. A paper describing the finding will be published online April 3 in Nature. Tony Wyss-Coray, Ph.D., professor of neurology and neurological sciences, is the senior author. The lead author...
