Actin is as essential to a cell’s function as Girl Scout cookies are to mine. With all of the biologists sorting out the many different functions and regulators of actin, it’s easy to get a little overwhelmed as a reader and actin admirer. Thankfully, a recent paper delves into the world of RhoA to clarify exactly what it is doing in our skin cells. RhoA is an actin small GTPase, which means it serves as a molecular switch to regulate actin cytoskeleton organization. RhoA is important in m........ Read more »

Space and time

by Janet Kwasniak in Thoughts on thoughts

p { margin-bottom: 0.08in; }
I have taken for granted that our sense of time is founded on our sense of space and that this is an example of embodied thought. A recent paper (citation below) examines this assumption and shows it far from clear.
Kranjec and Chatterjee say:
Is time an embodied concept? People often talk and [...]... Read more »

The Many Faces of Empathy

by Dr Shock in Dr Shock MD PhD


Based on recent literature and a lecture it appeared to me that not everyone is talking about the same phenomenon when it comes to empathy. In much animal research resonance is mostly the adequate description of what is being studied. Resonance is the phenomenon of one person unconsciously mirroring the motor actions as basis of [...]

A New Safe Blood Test to Diagnose Down Syndrome

by Laika in Laika's Medliblog

The established method to prenatally diagnose chromosomal gross abnormalities is to obtain fetal cells from the womb with a fine needle, either by Amniocentesis (a sample of the fluid surrounding the foetus in the womb)  or by Chorionic villus sampling (CVS, a sample of the placenta taken via the vaginal route). The procedures are not to be sneezed [...]... Read more »

Psycasm - The Cognitive Differences between Christians and Atheists.

by Rift in Psycasm


It's generally accepted that as a nation's mean IQ increases their irreligiousity increases too (Lynn, Harvey & Nyborg, 2009). That is, there's a negative correlation between Intelligence (as measured by IQ tests) and religious beliefs (be that belief in (a) God(s), an after-life, or super-beings). The Lynn, Harvey and Nyborg (2009) paper claims the relationship between g and &#; (read more)

Bubbles under the microscope

  As the data from the Milky Way Project are starting to come in, and Rob is making progress with the data reduction of  many clicks and drawings, I’ve been giving a lot of thought to these gorgeous bubbles we’re seeing. How were they created, why do they appear the way they do, and what [...]... Read more »

Rape Myth #1: She's Probably Lying

by Stephanie Zvan in Almost Diamonds

Tawana Brawley. Duke University men's lacrosse team.If you see a rape allegation in the news, those words aren't far behind. They are talismans, touchstones for the idea that we must never, ever forget that women lie about rape. These women lied; therefore, women lie.The truth is, of course, that some women do lie about having been raped. That shouldn't surprise us. People make false accusations about every type of crime, even murder, where it is excruciatingly difficult to do. If no woman ever ........ Read more »

Species abundance distributions and basketball

by Scott Chamberlain in Recology

A post over at the Phased blog (http://www.nasw.org/users/mslong/) highlights a recent paper in PLoS One by Robert Warren et al. Similar results were obtained in a 2007 Ecology Letters paper by Nekola and Brown, who showed that abundance distributions found in ecology are similar to those found for scientific citations, Eastern North American precipitation, among other things. A similar argument was made by Nee et al. in 1991 (in the journal PRSL-B). The author of the blog appears to agree with ........ Read more »

A paper which examined the over-diagnosis of breast cancer (referenced below) received more press attention than any other study I looked at. Coverage of cancer is ever-present in our newspapers, televisions and online media. From the latest way to reduce your chance of getting it, to new treatments and heart-wrenching stories of patients with the [...]... Read more »

Different Speeds have Different Meanings in our Bodies' Performance in Pain

by mc in begin to dig (b2d)

Every little thing in the complex systems that are us seems to impact every other thing - or at least a whole lot of other things.  Take speed.  Have you ever tried to do a familiar movement either really fast or really slow? Say whipping an egg in a bowl, making a shoulder circle, lifting a knee up and down. Speed changes performance, doesn't it? Something else we've seen change performance is pain: pain will change event what muscles get recruited,when performing an action. Recent r........ Read more »

Moving on up – Vertical migrations of Nautilus

by Mike Mike in Cephalove

If you like nature documentaries, you’ve probably seen the following clip (from the BBC’s “Planet Earth“): Nautiluses are really cool – they’re misfits among cephalopods, having many tentacles and external shells while their fellow squids and octopodes are squishy and eight- or ten-armed. In this clip, at least, they come across as sort of mysterious, [...]... Read more »

Supply Chain Risk Management Thesis (Impact of demographics on supply chain risk management practices)

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


This is somewhat of the fifth contribution to my series on doctoral dissertations, apart from not being a doctoral thesis but a master thesis on Supply Chain Risk Management. Nonetheless, an immense effort and dedication is spent on these works only to find the results hidden in the libraries. So the goal is raise interest in the research of my peers.

Willpower and the Unconscious on Automatic Pilot

by Shaheen Lakhan in Brain Blogger

What is the practical value of research delving into our sense of self? Willpower is one answer.

How Bacteria Swim in Your Stomach

Bowling together... in most of Europe, at least

by Tom Rees in Epiphenom

Ten years ago, the sociologist Robert Putnam created shockwaves with his analysis of the breakdown of US society in recent decades -

We sign fewer petitions, belong to fewer organizations that meet, know our neighbors less, meet with friends less frequently, and even socialize with our families less often. We're even bowling alone [Source: Bowling Alone].

Putnam's analysis of the causes was pretty nuanced (read: no-one really knows), but he did point out that the decline of religion in the US ........ Read more »
