Supply chain agility – Risk mitigation and response

by Jan Husdal in husdal.com

How does company culture shape a firm’s risk mitigation and response, and thus, how does company culture shape a firm’s supply chain agility? That is the research question asked by Michael J Braunscheidel and Nallan C Suresh in their 2009 article The organizational antecedents of a firm’s supply chain agility for risk mitigation and response. [ ... ]... Read more »

Fibromyalgia: Time for the rheumatologists to hand over?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living


The American College of Rheumatologists developed diagnostic criteria for fibromyalgia in 1990, the culmination of many years of debate and disparagement of the existence of this pain problem.  At the time, it was thought that it was a rheumatic complaint due to the presence of body pain and soft tissue tenderness, so the diagnosis and [...]...

Violating the Principles of Open Access

by Michael Long in Phased

Caroline Savage and Andrew Vickers (Memorial-Sloan Cancer Research Center, New York) have shown that many scientists who publish in technical science journals, under an open access agreement, are noncompliant with explicit data sharing requirements.

Broca’s area and the processing of hierarchically organised sequences pt.1

by Wintz in A Replicated Typo

Ever since its discovery in 1861, Broca’s area (named after its discoverer, Paul Broca) has been inextricably linked with language (Grodzinsky and Santi, 2008). Found in the left hemisphere of the Pre-Frontal Cortex (PFC), Broca’s region traditionally[1] comprises of Broadmann’s areas (BA) 44 and 45 (Hagoort, 2005). Despite being relegated in its status as the [...]... Read more »

optimizing your coffee consumption

by Alex Holcombe in ceptional

We live in an era where students, shift workers, and scientists increasingly consume drugs that modify brain activity in order to enhance cognition. Ethicists are right to fret about this as the number of addictive substances with some ill effects proliferates (DeJong et al. 2008). People will use these things regardless whether or not some [...]... Read more »

Vitamin D and sun bed UV

by Stuart Watson in Optical Futures

Light is good for your health. Most notably, there are significant health benefits from vitamin D, which is produced in our bodies by the absorption into the skin of ultraviolet (UV) radiation. There are also dietary sources of vitamin D, but one of the best and most enjoyable involves simply sitting back and soaking up the sun's rays.

Innate Immune Cells: Mediators of the Angiogenic Switch?

by Varun in Wissenschaft

The role of Matrix metalloprotease type 9 (MMP-9) in the activation of Vascular Endothelial Growth Factor (VEGF), the induction and maintenance of chronic angiogenesis and early stage tumor growth has been well established. But what is the source of MMP-9 ? In a study published in 2006, Nozawa and co-workers, using the RIP1-Tag2 transgenic mouse as a model, identified two inflammatory cell types, neutrophils and macrophages, as the major sources of MMP-9.The RIP1-Tag2 transgenic mouse is a well ........

Panic! In the fMRI Scanner

by Neuroskeptic in Neuroskeptic

Continuing the theme of interesting single case reports, I was pleased to see a paper about brain activity in someone who suffered a panic attack in the middle of an fMRI brain scan experiment.The unfortunate volunteer, a 46 year old woman, was taking part in an experiment looking at restless-leg syndrome. The scan lasted 40 minutes, and everything was going smoothly until quite near the end, when out of the blue, she had a panic attack.Obviously, the scan had to be abandoned, but the researcher........

Bees follow the crowd: Do whole-hive traits override individuals' genetics?

by Jeremy Yoder in Denim and Tweed

Social insects are often considered prototypes of group selection, in which the evolutionary interests of individual organisms are forced to defer to the needs of their social group. Now, the authors of a new study of honeybees argue that colony-level traits can override the genetic predispositions of individual bees [$-a].

Induced pluripotent stem cells with one transcription factor

by Charles Daney in Science and Reason

Just under three years ago, in October 2006, some important stem cell research was announced by a Japanese scientific team led by Shinya Yamanaka. The team showed how ordinary mouse skin cells could be transformed into cells that turned out to be pluripotent, just like embryonic stem cells (ESCs). The new cells were called induced pluripotent stem cells (iPSCs). Although "ground-breaking" is an over-used term, this research genuinely deserved the description.Aside from the fact that it could be ........ Read more »

Global warming and shifts in food web strucutre

by Marc Cadotte in The EEB and flow

Predicting the effects of global warming on biological systems is of critical importance for informing proactive policy decisions. Most research so far has been on trying to predict shifts in species distributions and changes in interactions within local habitats. But what many of these studies assume is that the basic biological processes and requirements of the individual species will not change -that is their biology is fixed and they simply need to find the place that best suits them. Not so........ Read more »

How many genomes did I just squash?

by Keith Robison in Omics! Omics!

Yesterday was a good day for catching up on the literature; not only did I finally get around to the IL28B papers I blogged about yesterday, but I also took a run through the genome fusion paper which is being seen as the fitting marker of the end of the "Communicated by" mechanism of PNAS (sample coverage by In The Pipeline and Science, though the latter requires a subscription).The paper, by Donald Williamson and communicated by Lynn Margulis, takes the position that " in animals that metamor........

Got Pain? Take Two Photos of Your Loved One and Call Me in the Morning

by David DiSalvo in Neuronarrative

Before our first son was born, my wife and I took labor preparation classes at the hospital. The instructor suggested that when the big day arrived, husbands (or partners) should bring to the hospital a photograph of someone or something that their wives love (kids, pets, family members, etc). While in labor, the instructor said, the photo will help the soon-to-be mother cope with the pain.

This seemed like decent counsel to me, though probably more of a “good feeling” suggesti........ Read more »

The psychological impact of adolescent obesity

by Travis Saunders, MSc in Obesity Panacea

The idea that adolescent obesity may provide a significant psychological burden is not terribly surprising. Adolescence is difficult under ideal circumstances, the physical stress and social discrimination that often accompany obesity could only be expected to exacerbate this situation (the ridiculously discriminatory advertisement at the top of this post may not be tolerable in today's society, but weight discrimination continues to increase in prevalence, with some arguing that it is now ........

Religion – A “Natural” Phenomenon?

by Shaheen Lakhan in Brain Blogger

All human societies have some phenomenon that can be described as religion. It is difficult to understand why religion is so pervasive in human culture. Some theories suggest that religion is a byproduct of evolution. However, no other animal group has anything that even remotely resembles the concept that has been labeled as religion in [...]...

Why middle-agers shouldn't join the army

by William Lu in The Quantum Lobe Chronicles

Enlisting in the army is a significant life-changing decision, especially for someone who's middle-aged. Apparently there's an age cap of 42 for active duty. The reasoning behind this seemingly arbitrary number is that it allow for a 20-year military career before retirement. However, perhaps they should look toward a younger cutoff point in light of a recent study investigating the effects of sleep deprivation on arousal levels of middle-aged rats. But before we continue with this line of argum........ Read more »
