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.

Dr. O'Reilly's advice is bad for patients.

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........

Sometimes it pays to blow the dust off those old archives. An Italian research team has been able to reconstruct how fish stocks in the Northern Adriatic Sea have changed over the last 200 years thanks to a creative method for transforming the diaries of long-dead naturalists and fishmongers into crunchable data. These long-ignored “eyewitness […] Read More »... Read more »

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........

We were all Africans…before the intermission

Quick review. In the 19th century once the idea that humans were derived from non-human ancestral species was injected into the bloodstream of the intellectual classes there was an immediate debate as to the location of the proto-human homeland; the Urheimat of us all. Charles Darwin favored Africa, but in many ways this ran against the [...]... Read more »

Playing God with Fruity Flies
