Scientists Move Closer to Understanding Schizophrenia’s Cause

Scientists Move Closer to Understanding Schizophrenia’s Cause | enjoy yourself | Scoop.it
A new study provides researchers with their first biological handle on the disorder, and helps explain why it often begins at a relatively young age.
Kenneth Weene's insight:

As a psychologist, I am excited by this contribution to our understanding of schizophrenia. Hopefully, this will lead to ideas for treatment and prevention, but for now at least it gives us a new understanding. Sadly, too much of a good genetic thing can be bad for one. So how can we monitor and reduce the expression of this particular genetic trait in young people who are at risk? Yet another reason for universal medical care.

Anorexia nervosa

Anorexia nervosa | enjoy yourself | Scoop.it
A study led by Howard Steiger, Ph.D., head of the Douglas Mental Health University Institute Eating Disorders Program, in Montreal, in collaboration with Linda Booij, a researcher with Sainte-Justine Hospital and an assistant professor at Queen's University, is the first to observe effects suggesting that the longer one suffers from active anorexia nervosa, the more likely they are to show disorder-relevant alterations in DNA methylation.
Kenneth Weene's insight:

In effect, prolonged dieting leads to even more prolonged dieting which in turn leads to other profound health problems. The simple message, don't push children to diet and don't push false body images on children.

Study suggests genetic link for male homosexuality

Study suggests genetic link for male homosexuality | enjoy yourself | Scoop.it
A large study of gay brothers adds to evidence that genes influence men's chances of being homosexual. But the results aren't strong enough to prove it.
Kenneth Weene's insight:

Is there anyone left who doesn't know that homosexuality is the result of genetics and not some choice? Well, anyone outside of places like Uganda and the American religious right where they don't believe that God actually works through the laws of science?

Feathered friends: researchers unveil bird 'family tree'

Feathered friends: researchers unveil bird 'family tree' | enjoy yourself | Scoop.it
By Will Dunham WASHINGTON (Reuters) - Scientists have unveiled the most comprehensive bird 'family tree' ever devised, using genetic data from 48 species to trace how modern bird lineages arose and flourished after the mass extinction that killed off the dinosaurs. The work by researchers from 20 countries helps clarify the evolutionary relationships of modern bird groups and reveals the genetic underpinning of traits such as singing, toothlessness, colorful feathers and color vision. ...
Kenneth Weene's insight:

Imagine that hummingbird outside your window, that robin singing, that parrot talking trash: all the wonder of birds. Now thing they all survived and were descended from the dinosaurs. Wow! Will they survive man? Will we cause another mass extinction?

More than a century after their discovery, we still don’t really know what blood types are for. Do they really matter? Carl Zimmer investigates.
Kenneth Weene's insight:

A fascinating and informative read. And, yes, there is discussion about the blood type diet fad.
