How Not to Respond to Negative Research – Addendum

by Rogue Medic in Rogue Medic

Does carboxyhemoglobin vary that much that a few seconds later, the HbCO is wildly different?

If that is the case, why buy a machine that will only give us a snap shot of a rapidly fluctuating and unreliable number?

Is there any reason to believe that carboxyhemoglobin changes that rapidly and unpredictably?... Read more »

The Epidemiology of Trauma in PTSD

by William Yates, M.D. in Brain Posts

PTSD represents a pathological response to a serious trauma. The evolution of the diagnostic criteria for PTSD has included a broadening of the types of trauma exposures felt sufficient to trigger PTSD.  The original criteria included combat, concentration camp confinement, natural disaster, rape or physical assault.  The current DSM-IV criteria for trauma require that "the person experienced, witnessed or was confronted with an event(s) that involved actual or threatened death or seri........

Prehistoric Clues Provide Insight into Climateʼs Future Impact on Oceans

by Allie Wilkinson in OH, FOR THE LOVE OF SCIENCE!

The Miocene marks a period in geologic time in which massive changes were occurring to Earth. Major landmasses came close to their present-day positions, and the closing of the Tethys Ocean ended the circumglobal circulation of warm waters. Modern patterns of ocean and atmospheric circulation developed, as gyres formed in the northern and southern hemispheres, [...]... Read more »

Mink Vs. Vole

by Journal Watch Online in Journal Watch Online

A mink stole may be stylish, but a live American mink can be an ecological nightmare. The carnivores have invaded habitats around the world, wiping out everything from native seabirds to fish. Now, Scottish biologists are reporting success in ousting the enemy with a “clear and hold” campaign of epic proportions.
Since 2006, a small, […] Read More »... Read more »

Music Therapy and Speech Production for Children with Autism

by Psychology 379 bloggers in Cognition & the Arts

It is estimated that for every 1,000 children born, two to six will be diagnosed with autism. Because of its relatively large presence, treatments and therapies for the impairments autistic children face are constantly being developed and improved. One of the most significant impairments associated with Autism is extreme difficulty in the development of speech and language. Some of the features of the language and speech impairment that autistic children face are unusual word choice, pronoun rev........ Read more »

Massive Magnets Reveal More Sex In the Brain

by Neuroskeptic in Neuroskeptic

"Is that a 7 Tesla magnet in your pocket, or are you just pleased to see me?"German neuroscientists Metzger et al report on the results of a study using the latest, ultra-high-field Magnetic Resonance Imaging to measure brain activity in response to sexually arousing stimuli.Most fMRI studies are done using MRI scanners with a field strength of either 1.5 Tesla or, most commonly nowadays, 3.0 Tesla. However, a few especially forward-thinking, by which I mean wealthy, research centres have starte........ Read more »

Simple Jury Persuasion: Don’t hate me because I’m beautiful…

by Rita Handrich in The Jury Room

It’s like that 1980’s shampoo commercial featuring Kelly LeBrock that seemed so silly.  “Don’t hate me because I’m beautiful…”. And decades later, we find that the sentiment is not only true, but we know it is true and we fear what will happen when others envy us! The research findings that we truly dislike the [...]

Fibre Supplement Can Decrease Glycemic Index

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

Yesterday, I blogged about the results of the DIOGENES study showing that a moderately high-protein diet, that also has a relatively low glycemic index, may be better for sustaining weight loss.
This post prompted a number of questions regarding the glycemic index (GI) - which most readers may recall refers to the relative speed with which [...]... Read more »

How Not to Respond to Negative Research

by Rogue Medic in Rogue Medic

That advice from Dr. O'Reilly may encourage us to return fire fighters to an environment that has already made them toxic, but with the mistaken belief that they have carboxyhemoglobin levels of zero, when their carboxyhemoglobin is really very high.

Dr. O'Reilly's advice is bad for Masimo investors.

Who writes health news?

by Hadas Shema in Information Culture

In times of financial difficulties, health reporters are usually the first to be let go. This is especially true if they actually know something about health (it makes them more expensive). Financial cutbacks mean that media outlets have to rely on news agencies or have non-specialist journalists report health. The authors of "Does it matter who writes medical news stories" are familiar with such problems (and their consequences), since they are reviewers of health news stories for the Australia........

Oil-eating bacteria

by Lab Rat in Lab Rat

Oil is formed from hydrocarbons: organic compounds which consist soley of the elements hydrogen and carbon. There are many, many different types of hydrocarbons, all of varying lengths and shapes, and pretty much all of them can in some way be consumed as an energy source by bacteria.Hydrocarbons, in both ring and chain form, taken from a mix of sourcesThe general rule is that the shorter and fewer rings present, the more toxic the compound to bacteria (ethalon, for example, is deadly) however t........

Thanksgiving and Football: Why you should always go for it on 4th and short

by Brad Walters in Cortical Hemming and Hawing

Today being Thanksgiving, it's pretty reasonable to assume (if you live in the U.S.) that you will likely be sitting down to a large meal involving lots of turkey, stuffing, and cranberry sauce.  It is also pretty likely, that somewhere in the house, football games will be on the television.  Which brings us to one of the quintessential questions in football: It's 4th down, your team is on the opposing team's 30 yard line and they have only one yard to go to get a first down.  Sho........

Common ancestry of life – Q.E.D?

by Tara Cronin in BioMed Central Blog

The proposition that “all the organic beings which have ever lived on this earth descended from some one primordial form”, first put forward by Darwin, and central to modern evolutionary theory, is a commonly held biological view.An attempt by Douglas Theobald, described in a letter to Nature as a ‘formal test’ of the universal common ancestry (UCA) hypothesis, stirred considerable interest recently - whilst the universality of the genetic code and evidence from comparative genomics prov........

Using beauty as an advertising tool - does it always work?

by BPS Research Digest in BPS Research Digest

Announcing that neuroscience writer Jonah Lehrer had been listed as one of Salon's sexiest men of 2010, psychologist and uber-blogger Vaughan Bell joked that an aftershave would soon follow. Vaughan was referring, of course, to the widespread tendency for marketeers to use beautiful people to promote products. The rationale of the tactic is obvious. By pairing a product with an attractive model, hopefully people will come to find the product attractive too. A new study by Debra Trampe and collea........ Read more »

Navigating by the (dead) stars

by Niall in we are all in the gutter

Until the last century, astronomy had one very practical purpose, navigation. Ancient mariners used stars such as the North Star and the Southern Cross to work out where in the ocean they were. With the advent of modern methods (the most up to date of which is GPS) navigating by the stars fell by the wayside. Now a new method that combines the ancient idea of stellar aids to navigation with some of the principles of GPS has been suggested to accurately determine the position of spacecraft, and i........
