Sedentary Physiology Part 1 – Not Just The Lack of Physical Activity

by Travis Saunders, MSc, CEP in Obesity Panacea

Image by kaibara87
Welcome to our 5-part series delving into the fascinating research being performed in the emerging field of sedentary physiology.  Today, we’ll start with an introduction.
As regular readers will know, sedentary physiology is one of our favourite topics here at Obesity Panacea.  Later this week we will be examining the relationship between sedentary behaviour (aka behavior) and health, as well as the mechanisms that are thought to mediate this association.  But before we ........

Amiodarone for Cardiac Arrest in the 2010 ACLS – Part III

by Rogue Medic in Rogue Medic

The research only demonstrates improved survival to admission, as if that does anything more than provide false hope and huge hospital bills. Why do we base the standard of care on such limited research?

Since there is no new amiodarone research, let's look at the old surrogate endpoint research that compares amiodarone with placebo. Keep in mind that this surrogate endpoint study is the basis for over a decade of still unproven treatment.... Read more »

Article review: Consensus methodologies in qualitative research

by Michelle Lin in Academic Life In Emergency Medicine

What types of methodologies are used to develop a consensus statement? I'm in the midst of helping to write a consensus statement manuscript in education and ran into this great review article. It's from the British Medical Journal in 1995. Basically, there are 2 general types of methodologies:Delphi ProcessNominal Group Technique Delphi ProcessAn example of a consensus topic might be: How will patient care be affected by the new ACGME Duty Hours rules? The Delphi process tak........ Read more »

How marsupial embryos develop (a short story)

by Captain Skellett in A Schooner of Science

Marsupials are just plain weird when it comes to procreating. I’m not talking about bifurcated penises (where the penis has two heads) although that’s pretty freaking weird. I’m talking about the embryos. When a baby marsupial is born after a 4-5 week gestation, it’s a tiny pink speck of nothing much. About the same size [...]... Read more »

Unquestioning dogma: the gatekeepers of science

by Björn Brembs in

This morning my friend Ramy reminded us of the recent spats over PLoS One publications (Darwinius, Red Sea) and how they were used to question the 'reputation' of PLoS One as a journal. Of course, it is about as meaningful to talk about the reputation of a journal as it is to talk about the reputation of the cover of a book. Journals are containers which say very little about their content. But on to the really relevant point:Specifically, Ramy pointed out how the current spat about a publicati........ Read more »

How To Cuddle Your Lady Right, by Smoove A

You are probably aware that Smoove A* is an authority on crustaceous love. Some have gone so far as to describe Smoove A as the authority on all multi-legged ladies. I am an amphipod (Gammara pulex), a microscopic crustacean that inhabits lakes and streams, and I cannot confirm or deny this report, I can only say . . . → Read More: How To Cuddle Your Lady Right, by Smoove A...

Blog: Qubits and Crypto

by Torah Kachur, Rheanna Sand and Brit Trogen in Science in Seconds

Secrets and lies define the government and military, that and being led by bumbling fools.  There is no doubt that some military information should be kept secret like technological advances, battle locations and strategies and George W. Bush's IQ.  For secrets to be kept away from Wikileaks, cryptography is essential.  The new type of cryptography that is being tested by the US military research division, DARPA, is quantum cryptography.  Because if codes like DaVinci&........

Violent Games increase Prosocial Behavior

by Dr Shock in Dr Shock MD PhD

Dr Shock is utterly biased when it comes to gaming. Especially when Call of Duty is used for research into the topic of possible negative or positive influences of exposure to violent games. This recent research with the action game “Call of Duty” did not support any negative influence of gaming on prosocial behavior or [...]

Science and Hype – Arsenic Life?

by Paul Vallett in Electron Cafe

One of the things that inspired me to write a blog about science is that I believe science does not have to be “dumbed down” for everyone to think that it is interesting. Researchers shouldn’t be afraid to use clear and understandable language to explain what is interesting about their results. Sometimes scientists (and science [...]... Read more »

[guest post: Alex Bradley, PhD] Arsenate-based DNA: a big idea with big holes

by Kevin Bonham in Food Matters

In the wake of the NASA excitement over the new arsenic study, and my promise to give a detailed review of the paper itself, I have recruited a colleague with strong opinons about the work, a solid chemistry and microbiology background, and "Dr." in front of his name to share his analysis. I will be posting my personal and less-technical take on the whole thing soon, so stay tuned.

Dr. Alex Bradley uses modern geochemistry and microbiology tools to study the evolution of life and Earth. He........ Read more »

Acupuncture, some dodgy maths and a cracking review paper

by Lorimer Moseley in BodyInMind

I have a challenge for you. Imagine you’re in ancient China and you’ve had this idea that health and disease hang on the flow of energy through invisible energy pathways called meridians that can be manipulated by applying needles in certain specific points. How do you go about systematically validating this theory? How do you [...]... Read more »

How do you spell "success" after bariatric surgery?

by Maureen McCormick in GourMind

The sweet smell of "success" . . . it's so intangible, so personal, so dependent on the point of view. Here's a sampling of what I have heard from patients:"I can buy clothes in a regular department store!"Often after years of buying shapeless clothes in specialty stores, many people - women and men! - enjoy trying on clothes in a department store, feeling stylish and reveling in colors other than black."I don't need a seat belt extender on airplanes anymore!

Bilingual Brains: Reading in Hebrew and in English

by Jason Goldman in The Thoughtful Animal

I've got an article that appeared in this week's Jewish Journal of Greater Los Angeles about recent research from Hadassah University on the neurobiology of bilingual (English-Hebrew) reading.

Is the English-reading brain somehow different from the Hebrew-reading brain? You might not expect any major differences; after all, both languages are alphabetic and are read more or less phonetically by breaking words into their constituent sounds. Compare English and Hebrew to a logographic language........ Read more »

Are we ‘illiterate listeners’?

by Henkjan Honing in Music Matters

'French babies cry differently as compared to German babies. This was the conclusion from a study that was published a year ago in Current Biology (see earlier entry). Three day old German babies cry in a downward fashion, their French contemporaries showed an increasing swelling of the cry and stop abruptly. It was a surprising observation, especially in the light of the general belief that in crying the pitch should always drop as a physiological consequence of the respiratory cycle. Apparentl........

searching for wormholes with general relativity

When you’re reading sci-fi stories in which some of the characters find themselves in need to cover hundreds or thousands of light years very quickly without a warp drive, they manage to make it through time and space via a convenient wormhole. It’s not the worst way to go since wormholes are supposed to exist, [...]... Read more »
