Brain Insula Signals Response to Depression Treatment
by William Yates, M.D. in Brain Posts
In a previous post, I reviewed a research summary of the potential for brain imaging to be a clinical tool in the diagnosis of brain disorders in the mood disorders domain.One of the key points in that review is the value of finding brain biomarkers for response to specific treatments.To follow up on this point, a recent research study has been published that proposes the brain insular cortex region may be key to determining specific treatment response in major depressive disorder.Helen Mayberg ........

by Usman Paracha in SayPeople
Main Point:
Scientists studied Martian meteorite obtained from Antarctica and found potential building block of life in it.
Published in:
PLoS ONE
Study Further:
Scientists have found good amount of boron in the rock. Boron is considered as the important element in the development of ribonucleic acid or RNA, which a nucleic acid that contains the sugar ribose. It is found in all living cells, and is essential for the manufacture of proteins according to the instructions carried by........ Read more »

Autoimmune disease as a risk factor for mood disorder?
by Paul Whiteley in Questioning Answers
Autoimmunity, the process by which the immune system fails to recognise self as self and subsequently targets those self tissues and cells, is something talked about quite a lot on this blog with autism specifically in mind. Part of the very wide and diverse immune-related features which have been discussed with at least some of the autisms in mind, it's not yet altogether clear exactly how and why autoimmunity is linked to behaviour but the association is an interesting one.Sally? @ Wikipe........

3 Ways Concept Maps Help You Learn
by Louise Rasmussen in Head Smart
Concept maps are pictures that that show how ideas relate to each other. In a concept map, ideas are represented as nodes, and the relationships between them as links with descriptive labels. Concept maps can be very large and complex—and they can be very small and simple. You can use concept maps to capture, communicate, and simplify [...]... Read more »

No Sex Drive? There’s A Pill For That

In my mind, pills are like apps. Do you have a common problem to solve? There’s an app for that, as Apple has trademarked. Do you have some health related issue? There’s probably a pill for that. Blood pressure? Check. Cholesterol? Check. Social anxiety? Check. Erectile dysfunction? Check. Obesity? Check. Female libido? Oops! No check! But just wait! Big Pharma is working on that!

Reversing the loss of brain connections in Alzheimer’s disease
by Bruce Lieberman in Beaker
The first experimental drug to boost brain synapses lost in Alzheimer’s disease has been developed by researchers at Sanford-Burnham. The drug, called NitroMemantine, combines two FDA-approved medicines to stop the destructive cascade of changes in the brain that destroys the connections between neurons, leading to memory loss and cognitive decline....

To Grow, Plants Do the Mathematics
by Andrew Porterfield in United Academics
You see them in sunflowers and artichokes. The familiar, concentric spiral-shaped Fibonacci sequence is part of a lot of flowering plants. These patterns precisely follow the Fibonacci sequence (1, 1, 2, 3, 5, 8), in which each digit (once you move along) is the sum of the previous two. But until now, nobody really knew how plants knew to make these mathematically precise patterns.... Read more »

How did sauropods get blood up their necks?
by Marc in Teaching Biology
Sauropods are the largest animals to have ever lived, surpassing whales even though they lived on land. Their unique anatomy, including their extremely long neck, has long been the subject of speculation and study, as their physiology must have stretched the limits of regular vertebrate capabilities. The topic of circulation is one central issue: how […]... Read more »

JUST PUBLISHED: Early Life Determinants of Reproductive Success
by Mark Rubin in The University of Newcastle's School of Psychology Newsline
Infertility is a rising problem around the world. Coupled with a current tendency to delay childbearing, the growth in the population of many countries has come to halt. Bacterial infections are an often overlooked cause for infertility. This is particularly relevant to the recent increase in Chlamydia infections among young people. When untreated, Chlamydia in pregnant women can be transmitted to the newborn. As a result, up to 15% of newly born babies are currently known to be infected with Ch........ Read more »
