Human Chorionic Gonadotropin (HCG) for Fat Loss: "Fallacy and Hazard"

by Travis Saunders, MSc in Obesity Panacea

Photo by Todd Huffman.

One of the great things about this site is that people often bring products or research to our attention that we otherwise might have missed. This occurred yesterday in the comments section of Peter's recent post on Acai berry scams, when one of our readers brought up the use of Human Chorionic Gonadotropin (HCG) in the treatment of obesity. The website that we were provided smacks of weight loss gimmickry - notably the promise of an obesity "cure" and "near 100% ........ Read more »

Ten Simple Ways to Increase Your Physical Activity

by Travis Saunders, MSc in Obesity Panacea

Photo by pugetsoundphotowalks.

Regardless of your shape or size, physical activity has been shown to add years to your life, and life to your years. But believe it or not, the benefits of physical activity are not restricted to exercise performed in the gym. In fact, one of the easiest ways to improve your health may be through increasing the amount of low intensity physical activity you perform throughout the day. For example, simply increasing the number of steps that you take each day is ........ Read more »

Spinach, Popeye, and Fishy Pigeons

by Dr. M in Deep Sea News

Originally, Popeye the Sailor gained strength from rubbing the head of a rare chicken. Not until 1932 and thereafter did Popeye gain superhuman strength and invincibility from downing a can of spinach. Besides being easier to carry than a chicken, spinach was purported to have extremely high levels of iron that would make [...]... Read more »

Milk, Prions and Evolution

by Pablo Astudillo in astu's science blog

Prion protein (PrP) is the focus of some neurodegenerative diseases. It is believed that misfolded prion protein (PrPsc, or “scrapie”) is the infectious agent responsible for bovine spongiform encephalopathy (BSE), and Creutzfeldt-Jacob disease (CJD), among others. PrPsc propagates by conversion of normal (healthy) prion protein (PrPc).
Several questions arise in the research community. Two of [...]... Read more »

The Perils of Fair-Weather Cocaine

by Dirk Hanson in Addiction Inbox

The higher the temp, the higher the death rate.
As spring approaches, cocaine users might take note of further evidence of a connection between high ambient air temperatures and accidental overdoses.
A study published recently in the journal Addiction used mortality data from the Office of the Chief Medical Examiner in New York City from 1990 to 2006 to determine the frequency of cocaine-related overdoses (itself an enterprise fraught with uncertainty and argument over listed causes of death).........

Correction on Intravenous drug administration during out-of-hospital cardiac arrest: a randomized trial.

by Rogue Medic in Rogue Medic

Also posted over at Paramedicine 101. Go check out the rest of what is there.In Intravenous drug administration during out-of-hospital cardiac arrest: a randomized trial,[1], [2] I missed some important information. I think I expected more detail to be in the text, than in the charts and figures, so I did not read Figure 2 carefully enough. Regardless of the reason, I did miss some important information.In response, Anonymous left this comment - RM: I was doing some reading on this article and c........ Read more »

Contingent flexibility

by Jan Husdal in

Can contingency planning increase flexibility and minimize risk exposure to supply chain disruptions? Obviously yes, but what is it about the contingency planning process that relates to flexibility? That question is asked by Joseph B Skipper and Joe B Hanna in Minimizing supply chain disruption risk through enhanced flexibility. Surprisingly, this article suggests that only [ ... ]...

Smell a lady, shrug off flu - how female odours give male mice an immune boost

by Ed Yong in Not Exactly Rocket Science

Sex might be fun but it's not without risks. As your partner exposes themselves to you, they also expose you to whatever bacteria, viruses or parasites they might be carrying. But some animals have a way around that. Ekaterina Litvinova has found that when male mice get a whiff of female odours, their immune systems prepare their airways for attack, increasing their resistance to flu viruses.

Litvinova worked with a group of mice that were exposed to bedding that had previously been soiled by ........ Read more »

Human and Chimpanzee Handedness

by Isabelle Winder in Going Ape

Of the many mysteries surrounding human evolution, the question of why humans, alone out of all the apes, display a strong tendency towards being right-handed is perhaps less well known than uncertainties about our locomotion, brain size and cultural capacity. Yet the fact remains, over 90% of humans are right handed, and strongly so - there are proportionally few left-handed individuals and very few ambidextrous ones. Handedness is a manifestation of laterality - having a behaviourally dominant........ Read more »

Weekly Dose of Cute: World's Biggest Bunny!

by Christie Wilcox in Observations of a Nerd

Often, the cutest things come in small packages. Not so with Ralph - at 42 lbs, he's a record-breaking rabbit.

Ralph comes from a huge family - both his mother and father previously held the world records for largest rabbit in length and weight. And though he's already the biggest bunny in the world, Ralph is still growing! No one knows how immense this ball off fluff will get, but however big he ends up being, he's sure to still be 100% adorable.

Gamma-ray bursts without the gamma rays?

by Charles Daney in Science and Reason

We discussed supernovae a bit in this recent post on gamma-ray bursts. There is now interesting new information on the connection between supernovae and gamma-ray bursts from two recently-described supernovae with atypical properties.Let's first review a little. Gamma-ray bursts (GRBs) are identified by detection of relatively brief (usually less than a few minutes) but highly energetic emissions of gamma rays. Although there's a great deal of diversity, most events fall into one of two categori........ Read more »

Let's Make Scotland More Active!

by PhD Blogger in Exercise Psychology

I thought i would post the Scottish Physical Activity strategy to demonstrate that a good strategy requires effective implementation. The document Preventing Overweight and Obesity in Scotlandidentified that Scotland was the third most obese country in the world after the USA and Mexico. This may actually be progress as until the report we were usually named as the second! Let's Make Scotland More Active is actually a very good strategy document. It was published in 2003 but progress has bee........ Read more »

Brain Scans Confirm: Men Like Curves in Women

by Wayne Hooke in The Psychology of Beauty

Platek & Singh (2010) report that stimuli depicting optimal waist-hip ratios (~0.70) activate the “reward center” in men’s brains; while stimuli depicting body mass index do not. They conclude that BMI preferences are therefore more culturally determined and, by suggestion, that WHR preferences are the result of evolved psychological mechanisms. I will point-out at the [...]... Read more »

Climate communication: Is fear collective action a winning strategy?

In a previous post from my series on why people don’t engage climate change, I described my interpretations of work by Susanne Moser and Lisa Dilling1, which suggested that the use of fear can be a poor way to motivate behavioral changes to deal with climate warming:

Nativism and Empiricism

Nativism and Empiricism
Do we come into the world with an innate understanding of the world, like baby geese seem to (for navigation)? Are the incredible navigational skills of ants and gerbils and other animals learned with experience, or are those animals born with those cognitive constructions of the world? What about for humans?

Availability decay of Bioinformatics web resources : Yes widgets can change it

by Abhishek Tiwari in Fisheye Perspective

Quality and availability of bioinformatics resources is always a matter of great debate. HTTP 404 not found is quite frequent phenomenon for bioinformatics researchers looking to use some published web accessible database or analysis tool. A 4-year follow-up survey on the lack of persistence of bioinformatics resources was published in year 2008 by Jonathan D. Wren suggests that approximately 20% of URLs published in MEDLINE abstracts are now inaccessible, and the most common types of inaccessi........ Read more »
