Diet and Physical Activity Reduces Cardiometabolic Risk in Severe Obesity

by Arya M. Sharma in Dr. Sharma's Obesity Notes

One of the important indications for weight loss in people with excess weight is to reduce their risk for cardiometabolic complication.
But, as regular readers of these pages are aware by now, diet and exercise may be of limited benefit, especially in individuals with severe obesity.
So exactly how effective are such lifestyle interventions in this population?
This [...]... Read more »

Managing Information Risks

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

At the moment I am looking for gaps in my reading up to now and I found that I have not read much about information risks. It also seems that those risks are not (yet?) in focus, neither in research nor business. So I was happy to find "Information risks management in supply chains: an assessment and mitigation framework" by Faisal, Banwet and Shankar.

Topic / Methodology
The purpose of the paper is to provide a framework for the management of information risks, and to device a way to meas........ Read more »

Social networking extends battery life

by David Bradley in Sciencetext

A new approach to social networking for mobile devices, such as tablet PCs and smart phones could improve the user experience as well as making connecting with contacts more efficient. The approach could also boost battery life by up to 70% by making use of shared data between users that are in the same location.

The RAD-57 Pulse Co-Oximeter – Does It Work – Part II

by Rogue Medic in Rogue Medic

Should anyone ever use a low RAD-57 reading to justify returning a fire fighter to a fire?


Sending a fire fighter, with a not-yet-detected elevated COHb, back into the fire is probably only sending that fire fighter back into the same environment that produced the not-yet-detected elevated COHb.

This is not the way to make good things happen.... Read more »

New Podcast: The fetal origins of later obesity

by Travis Saunders, MSc, CEP in Obesity Panacea

Image by euthman
Earlier this week I discussed the results of an interesting paper which suggested that obesity surgery in women could reduce the risk of obesity in their future children.  It generated some excellent discussion in the comments, with a few people expressing skepticism over the importance of the physiological mechanisms described in the paper (the discussion is ongoing, so feel free to head-over and share your two cents).  As luck would have it, I recently interviewed my friend........

A History of Mental Illness: Part 1 - The Gods Were At Work

by John Wayland in The Darwin Tribune

We've all heard the famous line "Those whom the Gods destroy, they first make mad". The author of this line is often debated. Some maintain it was written by Euripides, a Greek playwright who wrote famous tragedies (plays that explore human suffering).The version used here and often quoted, appears in Daniel Anderson Scott's 'Daniel: A Model for Young Men' on page 248.Whatever its origin, throughout the centuries man has believed that mental illness was the result of the........

Homozygosity runs in the family (or not)

by Razib Khan in Gene Expression

The number 1 gets a lot more press than -1, and the concept of heterozygosity gets more attention than homozygosity. Concretely the difference between the latter two is rather straightforward. In diploid organisms the genes come in duplicates. If the alleles are the same, then they’re homozygous. If they’re different, then they’re heterozygous. Sex chromosomes [...]... Read more »

Lunar lost and found

Forty years ago today the Lunokhod-1 lunar rover landed on the Moon.

A Brush with Madness

by Kristopher Hite in Tom Paine's Ghost

I'm giving myself ten minutes to do this. To write whatever storms into my mind then hit post.

I think the archaic revival might run into some barriers. Like starvation, no communication, and other electrical difficulties if it embraces the Abbey-esque Luddite philosophy entirely.

As much as I want to get onto that other boat I think I will just slip between the hulls and end up swimming by myself among the sea-monsters, bullets whizzing past my head with bubbles trailing behind in dark ........ Read more »

Re-Evaluating Ancient Beavers

by Andrew Farke in The Open Source Paleontologist

Beavers are some of the most distinctive (and largest) rodents around today. Two species of the extant beaver, Castor, are found throughout the northern hemisphere, and these animals have an enormous effect on their landscapes. Beavers are perhaps most famous for their dam-building activities, altering the flow of streams and generating valuable wetlands used by other animals. Surely, the impact of this group extends far back in geological time.Many early beavers were fossorial, or burrowing, wi........ Read more »

This is no Picnic – Seasonal Migration of American Black Bears is a Complicated Business

Organisms in search of favourable conditions commonly undertake long-distance migrations.  Birds, whales and sea turtles come to mind as typical species that spend a good deal of time on the move; however, there are many animals that undertake seasonal movements to a lesser extent.  Black bears (Ursus americanus) are not recognized as typical ‘round-trip’ migrators, [...]...

Winter active bumblebees

by Africa Gomez in BugBlog

We had our first frost yesterday, and it was also a frosty morning today. But coming back home this afternoon, with the light already going weaker, I came across a Tree Bumblebee, Bombus hypnorum feeding on a large Mahonia bush. I have posted before on this bumblebee, a recent natural colonist in the U.K. In the last two decades, reports of winter active bumblebees - mostly Bombus terrestris - have steadily been accumulating, especially in the south of Britain.

You are your brand label

by Tom Rees in Epiphenom

The last post, on how people find secular alternatives to fill one particular emotional need traditionally fulfilled by religion (the need to feel in control), set me to thinking about another study that was published earlier this year.

The study looked at brands, which are a powerful form of self expression. People use brands to send signals about personality and wealth. Many people are, in a very real sense, defined by their brands.

Religion, too, provides a powerful sense of identity. Whe........ Read more »

Brain MRI White Matter Intensities: Clinical Significance
