Science! Origin of Violent Rage Found in Male Mice

So, this has little to absolutely nothing to do with jiu jitsu, I just think it’s kind of funny to think of mice as having “violent rage”. A recent study published suggests they have found the neural circuitry that is responsible for unprovoked, violent outbursts from male mice.

While this doesn’t quite have any practical application to humans just yet, the article does mention, “this research may help map the neural circuitry that controls aggressive behavior, which could eventually lead to surgical treatment for humans.”

Check it out, and have a great day everyone!

Science! Study Suggests Seasons Can Actually Change Your Brain

Huh, this is interesting: a study was recently published which suggested different parts of the brain are more active during the different seasons.

“While these are interesting observations, [it is pointed] out that the team currently has no insight as to how this process could happen.”

Well, balls. It’s interesting to consider though.

Check it out and let me know what you think- otherwise, have a great day everyone!

Science! Exercise Does Not Always Mean Weight Loss

While we know anecdotally that exercise is not the all encompassing answer to weight loss, we now have science to back it up: a recent study showed that while there will be a significant spike in calorie expenditure when initially being more active, the body will eventually adapt and end up burning less calories.

Our bodies are almost frustratingly efficient sometimes.

Anyway, check out the article and have a great day everyone!

Science! Those Who Take Their Coffee Black May Be More Likely to Exhibit Psychopathic Tendencies

I’m just mentioning this because it involves one of my favorite things in life, coffee.

Not that this study should be taken as indisputable fact, but a recent study claims to have found that people who take their coffee black are more inclined to exhibit psychopathic tendencies:

“Looking at the taste preferences of 500 people, it was found that those who enjoyed bitter flavors over sweet flavors were more likely to exhibit signs of “Machiavellianism, psychopathy, narcissism, and everyday sadism.” The study, which was published in the journal Appetite, was conducted at the University of Innsbruck, Austria, by psychologists Christina Sagioglou and Tobias Greitemeyer.”

While 500 people may seem like a lot, that’s actually a pretty small sample size. There are a couple other elements to this study that are missing, so I’m really not taking this study seriously. Still, it’s interesting to consider.

Feel free to check it out while I sit here and sip my coffee (with creamer in it), and have a great day everyone!

Science! Vitamin D May Protect Against Cognitive Decline

Stock up on your vitamin D everyone.

According to an article on IFLScience, studies have shown there may be a possible correlation between a vitamin D deficiency and a decline in cognitive function, particularly for individuals over 60. According to one researcher quoted in the article:

“There were some people in the study who had low vitamin D who didn’t decline at all and some people with adequate vitamin D who declined quickly. But on average, people with low vitamin D declined two to three times as fast as those with adequate vitamin D.”

It would be a shame to learn all this jiu jitsu, and then lose it all later in life.

Now if you will all excuse me, I’m going to go sit in the sunshine, drink some milk, and then have some salmon and…something else really high in vitamin D.

Take a look at the article, and have a great day everyone!

Science! The Misleading “Pee in the Pool” News Story

I’m writing about this because I’m a little annoyed, mainly because it shows how infrequently people actually read the source material of a story. And I’m totally guilty of doing the same, but this is a reminder that we should check the source before sharing articles, stories, etc.

I’m sure you’ve seen the article I’m referring to, probably on Facebook:

“The CDC says it’s not chlorine that’s irritating your eyes, it’s pure URINE! Ewwww!”

Ok, slow your roll there, friend.

If you read the actual article posted by the CDC, found here, from what I understand that’s not actually what’s happening: the article actually talks about poor airflow in indoor pools and the buildup of byproduct created when chlorine binds to sweat, urine, etc to destroy them. Your body is irritated by the chlorine doing its job and disinfecting the pool, essentially.

I’m not terribly familiar with exactly how chlorine molecules work, but I’m pretty sure that’s what the CDC is trying to inform everyone of. If there’s a chemist out there in the peanut gallery, please by all means feel free to correct me, but I’m pretty sure that’s what their article is about. The article is also suggesting to reduce this buildup of byproduct and keep indoor pools well ventilated, and hey, maybe actually follow the rules of the pool and rinse off before jumping in (again, not pointing fingers- I’m sure we’ve all ignored that rule at LEAST once).

That’s all for today folks- now go out there and…don’t pee in the pool. Please.

Science! Excessive Intake of Vitamin Supplements May Increase Cancer Risk

You know how they talk about there being too much of a good thing? Apparently vitamin supplements can also fall under that category.

According to IFLScience, an article was published by the University of Colorado Cancer Center in which researchers analyzed data regarding vitamin usage and cancer, and found that those who took more than was necessary actually increased their risk of developing cancer. according to the post:

“We are not sure why this is happening at the molecular level,” explains researcher Tim Byers, “but evidence shows that people who take more dietary supplements than needed tend to have a higher risk of developing cancer.”

Ruh roh. The post goes on to assure us all not to panic, that these vitamins in the correct dosage should be beneficial for everyone.

Check it out, and have a great day everyone!
