On Numeracy, Bacterial Nanowires And Electrical Circuits

by Robert Deyes in Promega Connections

Our local library is all abuzz these days over a traveling exhibition that chronicles the life and works of America’s grand statesman, philanthropist and polymath Benjamin Franklin.  The tercentenary exhibition, bearing the title In Search Of A Better World, began in 2008 on a journey that, when finished, will have hit 40 libraries in 31 [...]...

All-Cause Mortality Risk and BMI

by William Yates, M.D. in Brain Posts

Elevated BMI (body weight in kilograms divided by height in meters squared) increases risk for heart disease and some types of cancer.  There is less data on the relationship and effect size on all-cause mortality.   A recent pooled study analysis of approximately 1.5 million adults in the U.S. provides important new data.The authors of the study pooled (aggregated) 19 longitudinal studies of white (non-Hispanic) samples.    The large sample size allows for controll........

Endogenous Electric Fields May Guide Neocortical Network Activity

by Bradley Voytek in Oscillatory Thoughts

(Note: this is a repost of my original post from 2010 Jul. I'm reposting some old posts to work within the ResearchBlogging.org framework.)I’ve been geeking out about this paper for a week or so now, so I just finally decided to put together a post about it to explain why I think it’s so awesome.I’ve been thinking about the foundations of electrophysiological research in neuroscience. The earliest experiments on the electrical properties of neurons were performed on giant squid axons becau........ Read more »

Science Careers: The Good, The Bad and The Starry

by Duncan Hull in O'Really?

Of all the things you can do with a Science degree, being paid money to stargaze from the top of a volcano in Hawaiʻi has to be one of the more interesting. Tom Kerr is one such lucky astronomer who has been managing operations at UKIRT (UK infrared telescope) – currently the world’s largest telescope dedicated [...]... Read more »

How clownfish help their anemones: nutrient transfer in a triple symbiosis

by Hannah Waters in Sleeping with the Fishes

The vision of a tropical beach is something we take for granted: the white sands, crystal blue water, and colorful, diverse reefs.  It’s like a playground designed just for us where everything is beautiful and comfortable (well, minus the sunburn).  But we actually shouldn’t take this for granted, as the existence of coral reefs in warm tropical waters is not a give-in, but rather the result of millions of years of slow evolution and coevolution to cope with this nutrient-poor ha........

Tip of the Week: BioGPS for expression data and more

by Mary in OpenHelix


This week’s tip introduces BioGPS, or Gene Portal System. We get a lot of questions about two things that BioGPS can help you to tackle: what do I do with a list of genes to find out what are? And the next question people have after that is: and where are they expressed? BioGPS can help you with both of those problems. It is a tool that integrates and displays many types of data that researchers would be interested in. It also allows you to customize your display with the types of data th........ Read more »

Overdoing it: Is there such a thing as too little anxiety in your witness?

by Rita Handrich in The Jury Room

Close your eyes. Think of a nervous witness you have had to prepare for trial. Beads of sweat on their upper lip. Nervous throat-clearing. Trembling hands. Shaky voice. Deer in the headlights expression. Testifying can be terrifying and we’ve all had the experience of attempting to take the edge off of the visible anxiety of [...]

Do TRegs discriminate?

by iayork in Mystery Rays from Outer Space

As I’ve noted several times before, regulatory T cells are important reasons for the poor immune response to tumors. TRegs are normal components of an immune response, “designed” to keep inflammation from running riot in general and to prevent responses to self-antigens in particular. Whether it’s because tumors are mostly (though not solely) self antigens, [...]... Read more »

Personalized Products and its Impacts on Supply Chain Design

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Experts from research and business alike argue that within the last decades consumers have grown to be a more demanding factor for supply chain management. At the same time manufacturing and supply chain strategies adapted to this development (from lean to agile, see Christopher and Towill, 2000).

But how are customer demands going to develop? Are we already seeing the decentralized manufacturing world, where everybody uses his own 3D printer to produce individual products on their desks? ........ Read more »

An increase in mitochondrial superoxide extends lifespan in C. elegans but not by hormesis?

by Colby in nutsci.org

Rate of ageing theories have evolved significantly over the years but now frequently centralize around the involvement of the mitochondria. Of recent (and seemingly on the way out) is the oxidative stress theory of ageing (formally the free radical theory of ageing), which is largely supported by correlational data. Recent genetic manipulation studies on the endogenous antioxidant network has caste considerable doubt over this theory.... Read more »

Is an unusual new galactic gamma-ray source a possible “dark accelerator”?

by mithy in The Enlightenment Junkie

In my last post on gamma-ray binaries, I mentioned that only a few of these exotic X-ray binaries (XRB) have been observed, and that they appear to fall into two distinct categories: microquasars, where the gamma-ray emission is caused by leptonic or hadroni particle interactions in the relativistic jet (Inverse Compton Scattering and Neutral Pion Decay respectively) and pulsar wind binaries. where the gamma-rays are [...]...
