Age-related changes in total and regional fat distribution

by Travis Saunders, MSc in Obesity Panacea

Unfortunately there are other negative changes in body fat distribution with age, including increased fat storage in the heart, liver, bone marrow, and skeletal muscle, all of which are associated with increased metabolic risk, as well as increased risk of fractures in the case of bone marrow. And as mentioned before, none of these changes are readily apparent when obesity is being measured by BMI or waist circumference alone, which are the most common measures used in the field (and which are ........

Longitudinal analysis of street Ecstasy content

by DrugMonkey in DrugMonkey

A topic that arises every now and again, particularly when I am discussing Ecstasy-related medical emergency and death, is the nature of the psychoactive ingredients in Ecstasy tablets. For definitional purposes, I consider 3,4-methylenedioxymethamphetamine (MDMA) to be what is considered by the vast majority of consumers to be canonical "Ecstasy".

It is reasonably well-established in the peer reviewed literature and the harm reduction effort that some fraction of Ecstasy that ........ Read more »

The birth of dragons

by Zen Faulkes in NeuroDojo

How did Komodo dragons evolve to be the world's biggest lizards?

The story goes that cartographers would write, “Here be dragons,” on the places of the map where they had no information. This would only be true in a few areas of the world, namely a few islands in the south Pacific, where Komodo dragons live.

As I talked about in an earlier post, weird things happen to the size of species on islands. Big species get small. Small species get big.

And if there’s one ........ Read more »

For the poor in NYC costs count more than calories

by Yoni Freedhoff in Weighty Matters

On July 18th, 2009 New York City's mandatory menu calorie law went into action and restaurants with 15 or more locations were forced to post calories on menu boards and/or menus for their patrons.The hope has always been that armed with this information people would choose fewer calories.Well, so far the results aren't too promising - at least not for a very specific population.In a paper published online in the journal Health Affairs, Brian Ebel and colleagues explored the purchasing behaviour ........

There is Money in Your Future

Algae bounced back after a knock

by Thomas Kluyver in Thomas' Plant-Related Blog

A number of mass extinctions punctuate the fossil record, dealing a sharp blow to life on Earth. The best known (although not the biggest) is the one that did for the dinosaurs, some 65 million years ago. Unlike some mass extinctions, there’s at least one smoking gun: a damn great rock crashed into the planet, [...]... Read more »

Rapid Resurgence of Marine Productivity After the Cretaceous-Paleogene Mass Extinction

by Greg Laden in Greg Laden's Blog

The course of the biotic recovery after the impact-related disruption of photosynthesis and mass extinction event at the Cretaceous-Paleogene boundary has been intensely debated. The resurgence of marine primary production in the aftermath remains poorly constrained because of the paucity of fossil records tracing primary producers that lack skeletons. Here we present a high-resolution record of geochemical variation in the remarkably thick Fiskeler (also known as the Fish Clay) boundary layer a........ Read more »

Does eating chocolate improve my mood as much as I think it does?

by Dave Munger in Cognitive Daily

I think I've mentioned here before that I'm a big fan of chocolate. I get upset when coffee shops in my area only bring out the chocolates in the afternoon. Who says you can't have a chocolate chip cookie for breakfast?

Chocolate, combined with a cup of coffee, helps me work all the way through to the end of the day, when I'd otherwise be tempted to call it quits in the late afternoon. So naturally I was excited when Greta found a research report on the effect of chocolate on mood. Could there ........ Read more »

What conclusions can we draw from Neanderthal DNA pt.1

by Wintz in A Replicated Typo

In recent times, genetic technology has progressed sufficiently to elucidate upon some of the questions normally preserved for archaeologists. One such question concerns the fate of a group of hominins that roamed Europe and East Asia for at least 250,000 years. During this time, this species adapted and endured some of the harshest environments on [...]... Read more »

Natural antibody protects against viral infection

by Vincent Racaniello in virology blog

Antibodies produced by infection with a virus, or after immunization with viral vaccines, are effective at preventing viral disease. However humans and higher primates contains “natural antibodies” which are present in serum before viral infection. Natural antibodies can activate the classical complement pathway leading to lysis of enveloped virus particles long before the adaptive immune response is activated.... Read more »

Simulations and Labs: Either/or?

by Kristen DiCerbo in Connections Research Blog

A lot of research into simulated environments sets them up in a “horse race” against hands-on laboratory activities in order to show that learning outcomes with simulations are at least as good as those from hands-on labs. But is it really an either/ or proposition?
Jaakkola & Nurmi (2007) looked at the possibilities of combining simulation [...]... Read more »

Does Sugar Make You Violent?

by Christie Wilcox in Nutrition Wonderland

If you read the nutrition science headlines, you might have seen these: "Giving in to pester power can make your child a thug" or "Daily sweets 'linked to violence'". They refer to a new paper that just came out which claims that eating sugary snacks every day as a child has an impact on your behavior as an adult. The idea seems impossible. I mean, sure, we all have thought about slugging that really slow guy in the line in front of us at the ice cream parlor when we're craving a nice, double sc........ Read more »

Vaccination against cocaine: Incremental advance

by DrugMonkey in DrugMonkey

I last broached the topic of immunization against drug use some time ago and I concentrated more on the ethical implications of vaccinating. I was being ever so slightly disingenuous because the current state of progress is not such that we need to consider such questions as:
Would you recommend it broad-spectrum for all children much like MMR?
Would you recommend parents be permitted to subject their drug abusing teen against his or her will?
Allow the courts to mandate inoculation?
Suppose it ........ Read more »
