Haboob - Intense Sandstorm Formation

Image via Wikipedia

   A haboob (Arabic هبوب) is a type of intense sandstorm commonly observed in arid regions throughout the world. There is almost no visibility in close proximity when inside the area covered by the haboob (as can be seen in the video below).

   During thunderstorm formation, winds move in a direction opposite to the storm's travel, and they will move from all directions into the thunderstorm. When the storm collapses and begins to release precipitation, wind directions reverse, gusting outward from the storm and generally gusting the strongest in the direction of the storm's travel.

   When this downdraft, or "downburst", reaches the ground, dry, loose sand from the desert setting is essentially blown up, creating a wall of sediment preceding the storm cloud. This wall of sand can be up to 100 km (60 miles) wide and several kilometers in elevation. At their strongest, haboob winds can travel at 35-50 km/h (20-30 mph), and they may approach with little to no warning.

Today I will introduce a series of posts entitled "Kinesiology:" which will deal with the interesting facts and information that I've learned throughout my years in university. If you could, give me your opinions whether you liked this post, and whether you would like similar in the near future in the comments section.

   I have finished a Bachelor of Science in Kinesiology and Health Science program, and know a reasonable amount of background information on the subjects pertaining to health and physical activity. Today I will start  off with a brief introduction to Myotomes and their testing.

   Myotomes are defines as a groups of muscles supplied by a single nerve root. It also has to be noted that spinal nerves come in pairs, one from the left side and the other from the right side. So an injury to a single nerve root (either right or left) is associated with muscle weakness (a.k.a. incomplete paralysis) of the myotome (left side or right side muscles) supplied by that nerve root. When testing a myotome, key muscles are tested for weakness, not pain.

Top 10 Most Extreme Substances Known on Earth

Here is a nice top 10 list of awesome Earthly substances, ranging form super-hot to the most darkest and the most magnetic to the super-fluid. So without any further adieu

10. The Darkest Substance Known to Man

What do you get when you stack carbon nanotubes on their ends and sandwich them together? A material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. Then add to that carbon nanotubes act as superconductors in certain arrangements, which makes them excellent light absorbers, and you have a perfect storm of black. Scientists are really excited about the potential applications of the substance; since virtually no light is “wasted”, it would be used to improve optical tools like telescopes, and even be used to make nearly 100% efficient solar collectors.

Keep your mouth shut about your goals and plans.

When you have some great aspirations in your life, shouldn't you announce them to your family and friends?
Isn't it good networking to tell people about your upcoming projects?
Doesn't the “law of attraction” mean you should state your intention, and visualize the goal as already yours?
Nope.

Tests done since 1933 show that people who talk about their intentions are less likely to make them happen. 

Announcing your plans to others satisfies your self-identity just enough that you're less motivated to do the hard work needed. 

In 1933, W. Mahler found that if a person announced the solution to a problem, and was acknowledged by others, it was now in the brain as a “social reality”, even if the solution hadn't actually been achieved. 

NYU psychology professor Peter Gollwitzer has been studying this since his 1982 book “Symbolic Self-Completion” (pdf article here) - and recently published results of new tests in a research article, “When Intentions Go Public: Does Social Reality Widen the Intention-Behavior Gap?”
Four different tests of 63 people found that those who kept their intentions private were more likely to achieve them than those who made them public and were acknowledged by others. 

Once you've told people of your intentions, it gives you a “premature sense of completeness.”
You have “identity symbols” in your brain that make your self-image.Since both actions and talk create symbols in your brain, talking satisfies the brain enough that it “neglects the pursuit of further symbols.”

 At first you might feel unable to hold all your goals and aspirations only to yourself, but you should try and do it gradually to see the most benefit from it. If you can't hold off telling someone your goal then try rephrasing it into a way that will not give you any social satisfaction or gratification. For example, instead of saying: "I've joined a gym and bought running shoes. I'm going to do it!" say something like: "I want to get into shape and become more fit, and if I slack off you should kick my ass or not talk to me for a while". That way you will be dissatisfied with your statement to a friend and will still be compelled to do your hard work to reach that goal later on.

Art meets science in a stem-cell exhibit

This year marks the 50th anniversary of the discovery of stem cells by Canadian scientists James Till and Ernest McCulloch, thus the Ontario Science Centre !dea Gallery has brought together scientists and artists to explore the intersection between art and the cutting-edge science of stem cell research.

This collaboration has inspired student artists and designers from a remarkable diversity of disciplines -including fashion design, science and medical illustration, and visual and textile arts - to respond with their personal visions of what stem cells are and what they mean.

Watch the animation made for this exhibition to find out more about stem cells.

Cannabis - what it actually does to your brain

   Scientists have known for a while that the active ingredient in cannabis was a chemical called delta-9-tetrahydrocannabinol, or THC for short. Ingesting or smoking THC has a wide range of effects, from the psychoactive "getting high" to the physiological relief of pain and swelling. It also acts as both a stimulant and depressant. How could one substance do all that?

Happy guys finish last, says new study on sexual attractiveness

We've heard it before: nice guys finish last. And when it comes to sexual attraction, it appears the rule holds. Women find happy guys significantly less sexually attractive than swaggering or brooding men, according to a new University of British Columbia study that helps to explain the enduring allure of "bad boys" and other iconic gender types.

Although some of you might be saying that everyone knows that women are more likely to be attracted to a bad-boy attitude, but here is some actual research to back that claim up. The University of British Columbia researchers who worked on the study say there's an inherent contradiction in this finding.

The Science of Persuasion Answers

Here are the answers to yesterday's Science of  Persuasion quiz along with a brief explanation on each. Few people had actually guessed very close to the actual answers. Congrats to you guys! I Hope you enjoyed it and if you are interested in more such quizzes please visit Daily Planet's Mind Bender via  Discovery Channel.


1. How many times should an idea be repeated for maximum effect? 
a) 3-5

Studies have found that the maximum effect came from 3-5 repetitions of an idea or message. Repetition fails if people aren't paying attention or if an argument is weak. If an argument is strong, repetition increases its power to persuade. However, too much repetition can have the opposite of the desired effect.

The Science of Persuation

I recently was watching TV and came up on a show that listed some awesome facts about the power of persuasion. The host basically gave a short quiz about the topic and listed a few plausible choices and then revealed the correct answer. I will try to reproduce that quiz in this post and you will have to take guesses as to what the right answer should be

How to develop good interpersonal skills in 10 steps

1. Try to address someone by their exact name. Remembering a person's name is a sincere sign of interest, is highly flattering, and never forgotten.

2. Never be afraid to make the first move, but try to be positive, not negative. Try to compliment, where possible

3. Aim to be clear, brief and courteous on the telephone.

4. Try to LISTEN more than you speak. You are likely to notice certain unspoken elements which would have otherwise gone unnoticed. Not only that, the person will feel you are genuinely interested in what they are saying.

5. Keep meetings short and interesting. Try to involve everyone present. It is easy to notice the articulate ones while you miss the ones who could really make a difference through some encouragement.

6. Praise first and criticize later, and only if you have to.

7. Make constructive criticisms, not destructive ones, bearing in mind that there are many routes to the same end. If you show colleagues how to build on what they already have it will be far more productive than destroying the foundations they've laid mainly for your own ego.

8. Try to be more persuasive than divisive. People will go to the ends of the earth for you if they feel valued and appreciated. It means you get much more done that way.

9. Always acknowledge another person's point of view, even if you disagree with it. Their view is important to them, just as yours is important to you. If there is a deadlock, think about it for a while and agree to differ, if nothing changes.

10. Above all, it is your right to express yourself freely, to support what you believe in, as long as you remember that this right also applies to everyone else and carries much responsibility for both compromise and sensitivity.

Amazing combustion of Mercury Thiocyanide

   Here is another chemistry related video, and this time it is combustion (burning of) Mercury Thiocyanate. This compound was formerly used in pyrotechnics causing an effect known as the "Pharaoh’s serpent" or "Pharaoh’s snake".

   It is a stable solid at room temperature that has the appearance of white powder with chunks; it can also be grey in color, depending on purity. Mercury compounds are extremely toxic and protective equipment should be used whenever working with Mercury Thiocyanate. 

   When the compound is in the presence of a strong enough heat source, a rapid exothermic reaction is started which produces a large mass of coiling serpent-like solid. An inconspicuous flame which is often blue but can also occur in yellow / orange accompanies the combustion. The resulting solid can range from dark graphite grey to light tan in color with the inside generally much darker than the outside.

Watch and be amazed by science!

Hardest World Languages

   Lets face it in our vastly interconnected world which is mostly caused by globalization, nowadays many people know more than one language. This can be very beneficial because one can easily communicate with others when they are abroad and can pretty much find their way around that new city easily. I, myself know three languages, in which I can fluently converse; they would be: English, Ukrainian and Russian.

   If anyone is interested in learning a new language for themselves, there is a vast amount of free tutorials, videos and lessons on the internet. One great resource is book2 - a website with hundreds of free mp3s that let you learn a new language anywhere you are ("The 100 lessons help you to quickly learn and use a foreign language in various situations").

   This leads to my next point - I wanted to find out what languages would be the hardest to learn from an English speaking perspective. My search led me to this great pictograph:
