The British Media's "Blonde Moment"

by Neuroskeptic in Neuroskeptic

Ten days ago, the Sunday Times - Britain's "newspaper of record" - recorded thatBlonde women born to be warrior princessesWomen with fair hair are more aggressive and determined to get their own way than brunettes or redheads, according to a study by the University of California... “We expected blondes to feel more entitled than other young women — this is southern California, the natural habitat of the privileged blonde,” said Aaron Sell, who led the study...Well who'da thought it.

Mirror The Body, Mirror The Emotion

by Cole Bitting in Fable

In their study, Evidence for mirror systems in emotions,1 Bastiaansen et al., examine the relationship between mirror systems and embodied simulation.

This examination highlights and advances the connections between body changes, emotions and the simulation of body changes and emotions. These systems also play a significant role in the creation of consciousness.2 The neuroscientific sense of body-mind connection provides great insight into the development of resilience and cultivation of well-b........

Presence of prion proteins in non-neuronal tissue in a case of variant CJD

by Brian Appleby in CJD Blogger

A recent article in the journal PLOS One describes a novel finding of abnormal prion proteins (PrPres) in additional non-neuronal tissues of a variant CJD (vCJD) patient.  The study comes from the National Prion Disease Pathology Surveillance Center, located at Case Western University in Cleveland, Ohio.  Prior to this study, there was evidence that PrPres was present in some non-neuronal tissues as shown below. The present study examined other tissues for the possible presence o........ Read more »

Is Homo floresiensis really that strange?

by zinjanthropus in A Primate of Modern Aspect

BMC Biology has recently published a paper (It’s Open Access!) which explores trends in brain size in the Primates.  A trend toward a larger brain is usually considered one of the “hallmarks” of the Primates, but Stephen Montgomery and his colleagues have shown that in many lineages, there is a trend towards secondarily “shrunken” brains.
The [...]... Read more »

How Can Haiti Be Sustainable?

by Eric Michael Johnson in The Primate Diaries

As I wrote yesterday in my piece for The Huffington Post, the history of Western financial involvement in Haiti has been one of growing the nation's textile industry despite the fact that 70% of Haiti's annual income comes from agriculture. By emphasizing programs such as HOPE and HOPE II, the United States has increased the profits of American companies, but the livelihood of Haitian workers has decreased at nearly the same rate.

Financial Risks and Reward Centers

Climate change drying up streams, reducing the reproductive success of bats in the Rockies

by Jeremy in Voltage Gate

Bats, as this article in Ecology explains, are particularly sensitive to these changes and, due to their enormous numbers, are integral to food webs as predator and prey. They may be that indicator ecologists are looking for.... Read more »

Where is paleontology?

by Andrew Farke in The Open Source Paleontologist

Last week, many of the leading journals in evolutionary biology - including The American Naturalist, Molecular Ecology, Journal of Evolutionary Biology, Evolution, and a number of others - announced a data archiving policy. In short, this policy states that the data behind the results of a paper should be publicly archived in well-known respositories such as Data Dryad, GenBank, or TreeBASE. Do you notice anything missing in this illustrious list of publications?Not a single one of those journal........ Read more »

Minimizing the impact of approaching boats on nesting shorebirds

by Rob Goldstein in Conservation Maven

If you ever walked along an empty stretch of beach and flushed away a flock of frightened shore birds, you might have wondered to yourself whether you just committed a horrible ecological sin.

Perhaps you asked yourself, "Where are those birds going? Did they just abandon their nestlings? How long until they come back? Or better yet, will they ever come back?"

A new study tries to answer these types of questions with respect to the impact of recreational boaters on nesting colonies of bla........ Read more »

Therapeutic Gene Silencing Strategies: An Introduction

by Rick Scavetta in DNA Dude

There has been quite a buzz circulating about the possibility of therapeutic gene silencing strategies. Today I want to take a first look at what these therapies mean.
One great example where gene silencing could be used is in polyglutamine disorders. This includes several disorders where genes accumulate, by replication errors, a repeat expansion of the [...]... Read more »

Santa's OK! Over 70 and overweight possibly a good idea.

There have been a number of studies of late that have concluded that being overweight (not obese, overweight) and elderly is in fact a good combination.Well, here's another.This study, published today in the Journal of the American Geriatric Society has Leon Flicker and his colleagues discussing the impact of weight on mortality over a 10 year period in 9,240 Australian men and women.Their findings?The minimum mortality risk was found at a BMI of 26.6 and as BMI decreased from there, risk i........

Our very own Tree of Eukaryotes

by Psi Wavefunction in Skeptic Wonder

Time to unveil what I've been up to for the past several Friday nights. I figured that after nearly a year and a half, and almost 20K page views, it's time for our blog to grow up a bit. What we need is our very own tree.Remember how I often refer to the Keeling et al 2005 tree when pointing out where some obscure organism lies on the 'map'? Well, that tree is 5 years out of date now. In fields like molecular biology and genomics, a lot can change in five years; compounded with how the protistan........ Read more »

The paradoxes of the Endangered Species Act (and how to fix them)

by Rob Goldstein in Conservation Maven

In a recent article in the journal Environmental Management, conservation biologist George Wilhere argues that the Endangered Species Act and its provision for habitat conservation plans are hampered by three main paradoxes: the Train Wreck Paradox, the Jeopardy Paradox, and the Maximum Mitigation Paradox. We interview George Wilhere and ask him how we can fix the problem...... Read more »

XMRV infection is enhanced by prostatic protein fragments

by Vincent Racaniello in virology blog

Fragments of an abundant protein produced by the prostate form amyloid fibrils that enhance infection of cells by human immunodeficiency virus type 1. These fibrils, called semen-derived enhancer of virus infection (SEVI), have been found to boost infection of prostate cells by the retrovirus XMRV. Is this evidence that XMRV causes prostate cancer?
Because most HIV-1 [...]... Read more »
