How Risky is your Company?

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Today I picked a special article on corporate risks. “How Risky is your Company?” by Robert Simons of the Harvard Business School. Its a more business oriented view on how companies should handle risks, internally. But since internal risk management can be seen as a part of supply chain risk management, I also include it here.... Read more »

More than just calories

by Rebecca Nesbit in The birds, the bees and feeding the world

In today’s population of just over 7 billion people, more than 900 million are undernourished and over 2 billion have nutrient deficiencies, yet over 1 billion adults are overweight. Lots of work has gone on to address the problems of undernourishment and obesity, but the problem of nutrient deficiency has taken second place.

Cradle of Cholera’s Seventh Pandemic Found

by Michelle Ziegler in Contagions

Cholera is a disease of seemingly endless fascination to epidemiologists for good reason. Vibrio cholerae emerged on a global stage in the 19th century just in time for the beginnings of modern medicine to grapple with it and for its transmission to prove the worth of epidemiological work. Although we understand its treatment and transmission [...]... Read more »

Can brain trauma cause cognitive enhancement?

by Bradley Voytek in Oscillatory Thoughts

Another post inspired by Quora. Someone asked the question: "Can brain trauma cause cognitive enhancement?".Obviously this topic is dear to me, so I felt compelled to answer.(Read previously on my TEDx talk, my Neuron paper on functional recovery after stroke, my PNAS paper on working memory network deficits after stroke, why we don't need a brain, and my discussion of Rep. Grabrielle Giffords' brain surgery).The full response to the Quora question is below.*****Maybe! But most likely only in ve........ Read more »

How much should we trust job applicant ratings of their own emotional intelligence?

by Alex Fradera in BPS Occupational Digest

Self-rating is a popular way to measure emotional intelligence in the workplace. Under lab conditions it's been shown that these ratings vary depending on what your (imaginary) objective is: to give a 'true' picture or to successfully win a job. A new study translates this lab finding to the workplace, finding that applicants for jobs really do rate themselves higher on EI than counterparts already working in that organisation.

The study compared scores for 109 job applicants with 239 volunteer........ Read more »

Walk Along the Paper Trail: Taste Hotsprings

by Michael Patterson in ...And You Will Know Me By The Trail of Papers

I haven't done many walkalongs about new papers, so let's review a new paper from Charles Zuker's lab.

Trail Prep

First, two pieces of background. There are two diametrically opposed theories of taste coding. The "labeled line" theory states that each taste quality (sweet, salty, bitter, etc.) is encoded by a single cell type, and individual cells respond to single taste qualities. In contrast,... Read more »

Hot hazy weather, violent behavior and the expert witness

by Doug Keene in The Jury Room

It’s really hot right now in Texas. We are in extreme drought. This weekend things became heated on my neighborhood email list when someone asked if our HOA had relaxed standards since so many lawns were brown. Multiple others took offense. Finally, someone recommended a cool glass of water for everyone. What’s amusing is that [...]

September 5, 2011

by Erin Campbell in HighMag Blog

When you hear the word “angiogenesis,” do you start hissing? Many of us associate angiogenesis with tumors on their way to becoming malignant cancer. Well, if it weren’t for angiogenesis, we’d all be in trouble. Angiogenesis is the formation of blood vessels from pre-existing ones, and is a key process during development.

Blood vessels are the tubular structures that transport all of the good stuff in our blood. The formation of blood vessels depends on angiogenesis, the process in ........ Read more »

Why Is Facebook So Successful

by Dr Shock in Dr Shock MD PhD

Buffer Because Facebook use can evoke a positive emotional state. Researchers have esthablished these positive responses during an expirement in which they measured several psychophysiological measures. They recorded skin conductance, blood volume pulse, electroencephalogram, electromyography, respiratory activity, and pupil dilationstate. They measured these psychophysiological patterns in 30 healthy subjects during relaxation condition, showing slides of [...]

Is It Possible to Not Judge A Book by Its Cover?

by Sam McNerney in Why We Reason

It’s an age-old aphorism preached to us by our parents, teachers, and coaches – Don’t Judge a Book By Its Cover. The lesson has manifested itself in a number of ways throughout history: Shakespeare said that all that glitters is not gold; MLK told us to judge a person not by the color of their [...]...

What explains HIV -induced pain syndrome?

by Connor Bamford in The Rule of 6ix



Does HIV-1 Tat protein induce pain in HIV/AIDS sufferers? Notice a Tat induced increase in activity when compared to control or inactivated protein. (Taken from: Chi, et al, 2011)

Pain is an extremely complicated symptom - just see the TED talk below on chronic pain, yet of the 33.4 million people currently living with HIV/AIDS worldwide, 90% will experience peripheral neuropathy - otherwise known as pain. This a general unrecognised and under-diagnosed (and under-treated) outcome of HIV infe........ Read more »

DNA of the Black Death at East Smithfield, London

It seems as though every couple of months a new paper is published reporting Yersinia pestis DNA from ancient remains.

Global Warming: Separating the noise from the signal

by Greg Laden in Greg Laden's Blog

A small "Signal-to-Noise Ratio" means that there is not enough real information (signal) compared to the background noise to make a definitive statement about something. With a sufficiently high Signal-to-Noise Ratio, it is possible to make statistically valid statements about some measure or observation. This applies to a lot of day to day decisions you make in life.

Climate change denialists understand this principle and they use it to try to fool people into thinking that "the jury is still........ Read more »

Do Cosmic Rays Cause Global Warming?

by Joel Rein in Moth Eyes

How do you make a cloud? Well, first you start with an aerosol particle, a small particle around which the much larger cloud condensation nuclei (CCNs) can condense. It takes a large CCN – at least 100 nanometres in size – for water vapour to be able to condense from water vapour. Clouds are made [...]... Read more »

Conservation and industry side by side

by Rebecca Nesbit in The birds, the bees and feeding the world

A paper published this month by researchers from the University of Alberta (Canada) looked at a trade-off between proposed industrial developments and protecting habitats the industry would destroy.

How you choose which areas of land to preserve is a much-debated issue. In this paper they worked on the premise that by protecting every ecosystem type in the area most species will have their needs met.
