Humanitarian aid is better when decentralized

by Jan Husdal in husdal.com

Humanitarian operations rely heavily on logistics in uncertain, risky, and urgent contexts, making them a very different field of application for supply chain management principles than that of traditional businesses. Decentralization, pre-positioning and pooling of relief items are key success factors for dramatic improvements in humanitarian operations  performance in disaster response and recovery. So say [ ... ]... Read more »

Hey there fluffy

by stajich in The Hyphal Tip

I spy a picture of Neurospora growing on the cover of Genetics this month.  The cover highlights the results from the work of the lab of Luis Corrochano who works on  light regulation in a variety of systems like Neurospora and Phycomyces.  This work describes their work on the fluffy gene which regulates conidiation (production of conidia [...]...

Adaptive radiation of “coywolves”

by DeLene Beeland in Wild Muse

Lately, “coywolves” have been making headlines and raising eyebrows. They are a wild canid that is a hybrid between a coyote and a wolf. It may sound like an urban legend, but coywolves are real.* I first learned about this quirky common name via a news article from The Star in Canada, Meet the Coywolf [...]... Read more »

Life between extinctions: cracking open the Cretaceous period

by Katie Kline in EcoTone

One hundred million years ago, Earth experienced its first great peak in biodiversity. Flowers emerged and with them pollinators, dinosaurs towered over newly evolved mammals and marsupials, the steaming jungles were teeming with newly arrived ants and termites, and the oceans were filled with gigantic, air-breathing reptiles. This was life during the Cretaceous period, Earth between two great extinctions.... Read more »

Fear of pain, not always fear of harm

by Bronwyn Thompson in Healthskills: Skills for Healthy Living


I know it’s actually Friday Funnies day, but before I go there I want to explore something I’ve been observing for a while.  Over the past four or five years, the TSK (Tampa Scale for Kinesiophobia) has been a really popular instrument for identifying and monitoring pain-related anxiety and avoidance.  It has been found to [...]...

Omega-3 Fatty Acids and Brain Cortex Activity

by William Yates, M.D. in Brain Posts

There is some research evidence to support the cognitive benefits of omega 3 fatty acids. These natural compounds are found in a variety of dietary sources including tuna, salmon and sardines. McNamara et al and colleagues at the University of Cincinnati recently published an interesting brain fMRI study of DHA (docosahexaenoic acid) supplementation. DHA is a key component of omega-3 fatty acids. Here are the key elements of the design:33 healthily boys age 8 to 10 years were randomizedSubjec........ Read more »

Prayer, but not belief in the afterlife, reduces anxiety of sick people

by Tom Rees in Epiphenom

It's clear that stressful situations can bring out the religious in people. What's not clear is whether turning to religion actually helps to relieve anxiety.Even less well understood is which, if any, aspects of religion are effective. Does the social support that comes with attending religious meetings help, or some other religious activity, or is it some facet of belief itself?Terrence Hill, at the University of Miami, and colleagues have looked at this using data from the US General Social S........

A Holin One

by Merry Youle in Small Things Considered

When time's up, an infecting phage lyses its host cell, thus releasing the assembled virions. (See our previous post for more about lysis.) This process has been intensively studied in the coliphage λ. Here the phage-encoded holin proteins are said to "permeabilize" the E. coli membrane, thus allowing the endolysins accumulated in the cytoplasm to pass through and attack the cell wall. "Permeabilize" has such a polite sound, suggestive of an orderly modification of the membrane to allow the fo........ Read more »

Amazing rats

by Richard Grant in Naturally Selected


by Brian Mossop
Ever since the size of our brains outgrew our closest animal relatives, we humans have declared ourselves far smarter than any other creatures in the animal kingdom.  But our big brains, and bigger egos, may underestimate the intelligence of other critters, simply because we’ve been asking the wrong questions. A study published in [...]...

Cultural Transmission in Chimpanzees

by Eric Michael Johnson in The Primate Diaries

Culture defines who we are but few can explain where it comes from or why we adopt one tradition over another. In the classic musical The Fiddler on the Roof the main character, Tevye, muses on this basic fact of human existence:

Here in Anatevka we have traditions for everything... how to eat, how to sleep, even, how to wear clothes. For instance, we always keep our heads covered and always wear a little prayer shawl... This shows our constant devotion to God. You may ask, how did this tradit........ Read more »

What is the impact of strict population control?

by Dave in The Daily Monthly

We’ve discussed some of the problems with increasing population, particularly in poorer countries. But what do attempts to deal with those problems look like?
China has implemented a notorious “one-child” policy since 1979 — over thirty years. While most people agree that this policy is a serious violation of human rights, the example of China is [...]... Read more »

Poverty of Stimulus and Ecological Laws

by Andrew Wilson in Notes from Two Scientific Psychologists

The first critique of Gibson's perceptual psychology came from noted cognitive scientists Fodor & Pylyshyn (1981). The critique was simply that Gibsonian information is an empty concept; however, this critique is ably addressed by Turvey, Shaw, Reed & Mace in the 'ecological laws' paper.... Read more »

How Men Respond to Sexual Victimisation

by Ultimo167 in Strong Silent Types

Weiss (2008) discusses some of the similarities and differences in how women and men experience sexual victimisation. That includes the fact that men are less likely to report having been abused to police, their emphasis on fighting back against male perpetrators, and in certain situations, blaming alcohol for their temporary loss of masculine control. ...

Storms and climate change

by Andy Russell in Our Clouded Hills

I’ve been pretty distracted recently with the Institute of Physics issue. I’ll hopefully draw that chapter to a close in the next couple of weeks (it looks like the IoP are going to stick their head in the sand and wait for it to blow over) but right now I’m bringing my current project [...]...

Weight ain't about exercise.

by Yoni Freedhoff in Weighty Matters

Not sure how many more posts will have the same title but yet another study has come out that suggests exercise doesn't have a tremendous impact on weight.This study, out of Harvard, tracked 34,000 women for 13 years and monitored their weight and their exercising.Only 13% of the women didn't gain weight over the course of those 13 years and those women began the study at a healthy weight and exercised on average an hour a day.For women who began the study overweight, no amount of exercise was s........

Pallimed Cited in the NEJM; Pallimed Readers Stand Up!

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

I am very pleased to announce that Pallimed has officially been cited in the New England Journal of Medicine! (members only).

The letter to the editor was written by my colleague at the University of Kansas, Lindy Landzaat, DO (a 2009 Harvard HPM Fellowship grad) based on Drew's post about Continuous-Flow Left Ventricular Assist Devices (LVAD).  This came about because I knew of Lindy's interest in LVAD's since she had presented at the 2009 Case Conference in Austin on the topic, and encou........
