Self report or functional assessment – or both?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

One of the more vexing problems in pain management is how to measure functional performance. I’ve written before about the problems with functional capacity evaluations (lack of predictive validity, poor reliability and so on), and these problems also apply to assessments of the ability to carry out activities of daily living. Amongst some of the … Read more... Read more »

Mediating burn-induced gastric impairment with insulin treatment

by EcoPhysioMichelle in C6-H12-O6 (old)

I’m trying to think my way through some of the results in Mechanisms of burn-induced impairment in gastric slow waves and emptying in rats by Sallam et al. This article (like almost all of the articles I talk about on this blog) is outside of my subfield in physiology, so I’m trying to apply the [...]... Read more »

Frilled dinosaur Mojoceratops is groovy baby, yeah

by Captain Skellett in A Schooner of Science

Mojo: The libido. The life force. The essence. The right stuff. What the French call a certain… I don’t know what.
Mojoceratops was discovered when Nicholas Longrich from Yale University was looking at existing fossils from American Museum of Natural History in New York. They had been classified as another species, Chasmosaurus, but Nicholas believed [...]... Read more »

The Science of Double Rainbows (OMG, what does this mean?)

by westius in Mr Science Show

This question came in from @holabendez for Science Week. What causes a double rainbow? The question is inspired by, in my opinion, the best youtube video since Keyboard Cat met Hall and Oates. Check out the Double Rainbow video below - if I'm this happy for just one day in my life, it will have been a happy life:

And now you'd better check out the Double Rainbow Song....

Rainbows are the result of the reflection and refraction of light by water droplets. They can be seen when there are wa........ Read more »

More hybrid lovin’: coywolves, wolves and coyotes…

by DeLene Beeland in Wild Muse

Is it a wolf? No. A coyote? No. A mixture of the two? Oh, yes. Northeastern wild canids have been leading biologists on a wild goose chase recently, as science scrambles to catch up with just what, exactly, Mother Nature has been cooking up in Massachusetts. Reports of extra large eastern coyotes have been rolling [...]... Read more »

Forget your worries with religious zealotry

by Tom Rees in Epiphenom

When animals are made to feel anxious and frustrated, they often turn to displacement activities - goals which may be irrelevant, but which they can at least achieve. Rats may run so eagerly on wheel that they starve themselves to death. Dogs may lick themselves so repetitively that they develop skin lesions. But what do humans do?

One thing we can do, according to new research by Ian McGregor and colleagues at York University, Toronto, Canada, is to become more fervent in our pursuit of cheris........ Read more »

Do sea snakes anticipate the onset of tropical storms?

Paul, the ‘Psychic’ octopus who can apparently predict* World Cup football match results, has inspired a lot of silliness attracted a lot of media attention recently. But can any other marine organisms see into the future? Sea snakes of the genus Laticauda (Fig 1.) are not entirely aquatic – not only must they regularly return [...]... Read more »

Clam attacks and kills oystercatcher

by Darren Naish in Tetrapod Zoology

Another one from the annals of weird deaths. Believe it or don't, wading birds sometimes get their toes or bill-tips caught in bivalve shells, they remain trapped, and they then drown when the tide comes in. Here is rare photographic evidence of this behaviour...

Disruption-Management Strategies for Short Life-Cycle Products

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

In his 2009 paper Brian Tomlin analyzes strategies to mitigate disruption risks in a three echelon supply chain.

Focus in his research is a single company, with its suppliers and customers. The objective is to maximize expected utility, while demand and supply are uncertain. There are two products available which can be used as substitutes. The time horizon for the decision maker is one season where the products can be sold.

Three different sourcing structures are considered.

Low-Carb Mediterranean Diet Improves Glucose Control and Heart Disease Risk Factors in Overweight Diabetics

by Steve Parker, M.D. in Advanced Mediterranean Diet

A low-carbohydrate Mediterranean diet improved HDL cholesterol levels and glucose control better than either the standard Mediterranean diet or American Diabetes Association diet, according to Israeli researchers reporting earlier this year.
Prior studies suggest that diets rich in monounsaturated fatty acids (olive oil, for example) elevate HDL cholesterol and reduce LDL cholestrol and triglycerides in type [...]... Read more »

Antarctic octopus venom

by Mike Mike in Cephalove

In my recent quest to find new, cutting-edge research on cephalopods, I've come across some neat stuff (check out this post on the perception of polarized light by cuttlefish - it's one of my favorite new cephalopod research topics!)  The study I'll review here is outside of my field of relative expertise, but it's so neat and so new that I couldn't resist writing about it.  It's good to step out of one's comfort zone every once in a while, right?An international team of researchers ha........

hold on to your protons. this could be huge…

by Greg Fish in weird things

As Professor Farnsworth would say, shocking news everyone! A new experiment says that we’ve consistently been overestimating the size of protons by about 3 × 10^-14 millimeters, and the physicists who measured this discrepancy by tracking the motions of electrons’ much heavier siblings, are clutching their chests in fear that they might’ve broken a law [...]...

Log Normal Distributions in Ecology ~ multiplications complications

by apeescape in mind of a Markov chain

The normal distribution is the “norm” when applying statistics to data. It is simple to interpret, simple to predict, simple to optimize, convenient software-wise and analytically elegant. But in many applications, this modeling assumption may not be optimal. The first is that the normal distribution doesn’t have a zero bound. In ecology, the data is [...]... Read more »

Breeding, Biotech and Bulls

by Matt DiLeo in Biofortified

I’ve been meaning to tell this story for some time. It’s a good example of how not all biotechnology is genetic engineering. Traditional Breeding In trad breeding, the breeder/gardener simply crosses two parents that show great (and complementary) traits, grows up the offspring, selects the best and repeats. It’s effective, slow, labor intensive and limited by the perception of the breeder. Most traits are also very heavily impacted by the environment, so each new Continue read........ Read more »
