Myostatin Deficiency
Myostatin (also known as growth differentiation factor 8) is a secreted TGF beta protein family member that inhibits muscle differentiation and growth. Myostatin is produced primarily in skeletal muscle cells, circulates in the blood and acts on muscle tissue, by binding a cell-bound receptor called the activin type II receptor.[1][2] In humans, myostatin is encoded by the MSTN gene.[3]
Animals lacking myostatin or animals treated with substances such as follistatin that block the binding of myostatin to its receptor have significantly larger muscles. Myostatin is active in muscles used for movement (skeletal muscles) both before and after birth. This protein normally restrains muscle growth, ensuring that muscles do not grow too large. Mutations that reduce the production of functional myostatin lead to an overgrowth of muscle tissue. Myostatin-related muscle hypertrophy has a pattern of inheritance known as incomplete autosomal dominance. People with a mutation in both copies of the MSTN gene in each cell (homozygotes) have significantly increased muscle mass and strength.

Well, I guess eugenicists win this round.
The Worst Date Ever
I'm a big fan of bodybuilding.com forums and some of the people on those forums have very messed up stories. If you haven't yet read this story, follow the link and read it beginning to end. I promise that you will laugh HARD. Warning: It is a bit graphic. Some profanity is included. So if you can't handle a small dose of profanity, you might want to put on your e-seatbelt. MS paint images are included; they are quite hilarious, along with the rest of the story.

Understanding the 'Left' and the 'Right'
The map below, in my opinion, provides an accurate representation of today's 'Left' and 'Right'. If you've ever been curious about politics, and/or the general views of the 'Left' and 'Right', this might be the day your curiosity meets satisfaction.
This map isn't the finest piece of art, if considered as such. Not all 'Leftists' and 'Right wingers' match this description, hence I would not suggest prejudice thoughts about all stockbrokers belonging to the 'Right.' I think the cartographer meant to produce irony, painting the 'Left' in red and the 'Right' in blue, or just being idiotic. One of the two.
Like what you see? Follow my blog. You can expect to see updates about random affairs.

Nutrition
If you've ever wondered about supplements and how the nutrition industry operates, you will learn a lot by reading Pogue's blog. Pogue lists the best supplements for the dollar, with citations of scientific research to support his point. In his blog, he reaches out to the beginners and pros of fitness, discussing supplements such as Protein powder, Creatine, Multivitamins, and supplements which do no more for your body than a placebo.

6 days a week
Eating sure is good. However, did you know that a lot of sea food contains high levels of mercury?
The complexities associated with mercury transport and environmental fate are described by USEPA in their 1997 Mercury Study Report to Congress. Because methylmercury and high levels of elemental mercury can be particularly toxic to a fetus or young children, organizations such as the U.S. EPA and FDA recommend that women who are pregnant or plan to become pregnant within the next one or two years, as well as young children avoid eating more than 6 ounces (one average meal) of fish per week.
In the United States, the FDA has an action level for methylmercury in commercial marine and freshwater fish that is 1.0 parts per million (ppm). In Canada, the limit for the total of mercury content is 0.5 ppm. The Got Mercury? website includes a calculator for determining mercury levels in fish.
Species with characteristically low levels of mercury include shrimp, tilapia, salmon, pollock, and catfish (FDA March 2004). The FDA characterizes shrimp, catfish, pollock, salmon, sardines, and canned light tuna as low-mercury seafood, although recent tests have indicated that up to 6 percent of canned light tuna may contain high levels. A study published in 2008 found that mercury distribution in tuna meat is inversely related to the lipid content, suggesting that the lipid concentration within edible tuna tissues has a diluting effect on mercury content. These findings suggest that choosing to consume a type of tuna that has a relatively higher natural fat content may help reduce the amount of mercury intake, compared to consuming tuna with a low fat content. Also, many of the fish chosen for sushi contain high levels of mercury.
According to the US Food and Drug Administration (FDA), the risk from mercury by eating fish and shellfish shall not be a health concern for most people. However, certain seafood might contain levels of mercury to harm an unborn baby (and especially its brain development and nervous system) or in cases of young child's interfere with the development of the nervous system. The FDA provides three recommendations for young children, pregnant women, and women of child-bearing age:
- Do not eat shark, swordfish, king mackerel, or tilefish because they might contain high levels of mercury.
- Eat up to 12 ounces (2 average meals) a week of a variety of fish and shellfish that are lower in mercury. Five of the most commonly eaten fish and shellfish that are low in mercury are: shrimp, canned light tuna, salmon, pollock, and catfish. Another commonly eaten fish, albacore or big eye tuna ("white") tuna depending on its origin might have more mercury than canned light tuna. So, when choosing your two meals of fish and shellfish, it is recommended that you should not eat more than up to 6 ounces (one average meal) of albacore tuna per week.
- Check local advisories about the safety of fish caught by family and friends in your local lakes, rivers, and coastal areas. If no advice is available, eat up to 6 ounces (one average meal) per week of fish you catch from local waters, but consume no other fish during that week.
These recommendations should be are considered when feeding fish and shellfish to young children, but in proportionally smaller and controlled quantities.
