The Wonderful Coconut
Posted on April 30, 2013 Comments (5)
One of the treats of living in a tropical climate is drinking coconut water. I love drinking the water from fresh coconuts. This video provides insight into the many uses of all parts of the coconut tree.
The Truth About Coconut Water by Kathleen M. Zelman, MPH, RD, LD – WebMD
…
There are some health benefits to consuming coconut water. It’s an all-natural way to hydrate, reduce sodium, and add potassium to diets. Most Americans don’t get enough potassium in their diets because they don’t eat enough fruits, vegetables, or dairy, so coconut water can help fill in the nutritional gaps.
Beyond that, the scientific literature does not support the hype that it will help with a laundry list of diseases. “There is a lot of hype about coconut water, yet the research is just not there to support many of the claims and much more research is needed,” says Cheung.
I have tried bottled coconut water which was pitiful. I don’t know if that was just a bad type and good options exist or the fresh stuff is just much much better. But I’ll stick to fresh coconut water as long as I can.

Pew Science and Technology Knowledge Quiz
Posted on April 25, 2013 Comments (2)
The Pew Science and Technology Knowledge Quiz is a simple 13 question quiz to get a very simple look at scientific understanding in society. Obviously these types of quizes are just extremely simple views, still it is interesting to see how you can do and what questions people struggle with.
I am surprised the fewer than 50% of the people got 2 true or false questions correct, including “Electrons are smaller than atoms. Is this statement…” Looking back at my previous post, I guess I shouldn’t be surprised, in the 2009 Pew Science Knowledge Quiz it is also the case that under 50% got the are electrons smaller than atoms question right.
They also provided a breakdown by demographic factors. Men had better percentages of correct answers, for the 2 true or false questions men were correct 55% of the time while women got 40% correct. The two other true of false questions had much higher correct answer rates 77% (83% for men 72% for women) and 66% (70 for men, 63 for women).
There was also a substantial tendency for the youngest ages to do better and the performance to decline for each age group. I am not surprised by the question answered incorrectly most often (only 20% got it right), see if you can guess which it is.

Engineers Save a Life

This photo was taken by the driver’s parents when they arrived. It doesn’t show much of what it went through to get there, but it gets most of the point across. The picture was taken 200 feet away and looking down from the road.
I shouldn’t be alive discussion on Reddit.
cmdshftn: Great engineering saved your life. The vehicle’s safety systems from the seatbelt to the crumple zones to the design of the seat kept you safe and alive despite all hell going on around you. Please write a letter to the manufacturer thanking their design team, but above all, follow up with whoever you need to in that jurisdiction to find out why there isn’t a guard rail on that road! Vehicle safety helps, but great road design to prevent an accident like yours helps more!

Can You Effectively Burn Calories by Drinking Cold Water?
Posted on April 15, 2013 Comments (1)
Neil deGrasse Tyson stated on Twitter:
What if your body is trying to cool down? I would imagine we have to use energy to cool off (though I am no expert on this)? So if you drink cold water and your body has less need to cool off, couldn’t this actually end up “saving” your body needing to burn calories – and thus cause yourself to gain weight?
This model would be similar to a server room that was cooled with air conditioning and cold winter air to cool off the servers. If there was less cold air used then more electricity would be used running the air conditioner to cool down the servers. I don’t know if it is a decent analogy though – maybe that isn’t an usable model for how we cool off.
I know we cool off partially by pushing water out onto the exterior of our skin to have it evaporate and cool us off. I would think that takes energy to do.
I do get that it takes energy to raise the temperature of the water you consume. It does make sense to me that if you were cold (like say I was during the winter living in the house I grew up in) you would use energy raising the temperature of the water.
What the overall energy situation is if your body needs to cool down seems questionable to me. Please let me know your thoughts. In any event his statement is accurate. It is just that the implication may lead people astray; that you can consume 1,200 Calories extra to balance the 1,200 Calories drinking cold water uses (or loss weight by having reduced your excess Calories by 1,200 if you eat exactly the same things you would without the cold water).

Building A Better Bed Bug Trap Using Bean Leaves
Posted on April 11, 2013 Comments (0)
Building A Better Bed Bug Trap
…
Although its mechanisms weren’t known at the time, the tactic dates back to at least 1678, when the English philosopher John Locke wrote of placing kidney bean leaves under the pillow or around the bed to keep bed bugs from biting as he traveled through Europe.
In the early twentieth century, the approach was also common throughout the Balkans, according to a 1927 report from the Imperial and Royal Austro-Hungarian Army. That report suggested the leaves stunned the bloodsucking bugs as they traveled from hiding places to their sleeping hosts during the night; in the morning, the bug-covered leaves were removed and burned.
…
“The inconvenience of bean leaves is that not everyone wants them scattered around their bed room.” Synthetics mimicking the surface of the bean leaf, however, could be placed “as a ring around the bed legs, a floor mat at the door, a strip on the bed board, it could be something one put’s in one’s suitcase,”
Very cool. The chemical assault on bed buds is failing all over the world. A new vector to assist in the fight against bed bugs will be most welcome. It is interesting to learn the scientific reasons that explain why some folk remedies work.
