In each day of our life, we see inflammation. We see it during sore throats and abscess formations in our bodies, and even slight tooth pain is a form of inflammation. Sometimes it's good when it fights to protect us from invading organisms, but sometimes it becomes bad when it occurs in inappropriate ways, like acne.
Do not ever laugh or shrug off what medical bottles or boxes give you as side effects or warnings. All of the side effects and warnings are put on the medication for a purpose. Priapism is a topic we all laugh or giggle about but it is a very serious emergency problem.

What is Pulse Pulse is that weird sensation that we feel when we palpate the skin overlaying an artery.
In a previous article, I showed how to make a powerful airsoft BB machine gun with a portable air supply using about $50 worth of PVC and air fittings. For this project, I have simplified the design to make a machine gun out of only 4 parts totaling about $15 that runs directly off of an air compressor.
Though it's unlikely you'll ever have a need for hostage survival skills, it never hurts to take in a few tips on what to do in the event of being accosted by Somali pirates off the Horn of Africa. Wired has tracked down a HowTo guide that addresses such a scenario. Though most of the advice is fairly general, one important point addresses the dangers of lighting up with the enemy:
This weekend in a jungle estuary, the DEA and local Ecuadorian police seized a prototype narco sub that may be the most sophisticated one yet. Complete with air conditioning and periscope, this 100 foot creation would have carried a more cocaine tonnage than any previously captured narco sub. To give you a perspective on the resourcefulness of these outlaws, consider this. A U.S. Navy Virginia Class attack submarine will run around $2.8 billion. But a drug lord in Cartagena would make you one...
Cortisone containing topical ointment and creams have various effect on the skin depending on its chemical nature plus the concentration of cortisone within it.
Also called hull-less watercraft or flapping wing propulsion vessels. Bounce up and down to make the wing fly and propel you across the surface of the water. If you stop, you fall. It's like a human powered water ski Fly a human powered hydrofoil.
Natural processes often create objects that have a fractal quality. Fractal branching patterns occur in plants, blood vessel networks, rivers, fault lines, and in several electrical phenomena. Many of these processes take lifetimes, or even occur on geological timescales. But this is not the case for electrical phenomena. They often occur near instantaneously. One example would be the branching patterns that sometimes occur in lightning.
It’s that time of year (in the U.S. anyway) when people are focused on getting organized -- or rather wishing they were organized. Being organized is great, it affords physical space, mental space and all but insures higher efficiency. But wishing and doing are two entirely different things. Wondering how to achieve the bliss of knowing where your stuff is? It’s easy... if you start small and don’t waste your valuable time watching TV shows or reading magazine articles on “how to” do it.

The immune system is not as simple as you might think. Simply, it's formed of two main groups of cells:
What is a burn? It's a form of injury to body tissues which is caused by heat, corrosive substances or friction. There is another form of burn, which is known as scald; it results from exposure to hot water or steam.

Halloween will be here in just over a week, which means next week these Scrabble Bingo of the Days will become more horrific. This week, there's just a few relevant Halloween seven-letter words for your Scrabble vocabulary, referencing witchcraft and one of the eeriest horror movies of all time, The Thing (not this year's version).

I am writing this quick post in response to the recent earthquakes and tsunamis that are affecting Japan. As soon as the news broke, and we began to hear of tsunami warning for our area, I immediately realized how under prepared I was for a natural disaster. The thing that drove this point home even deeper was the number of people asking me for advice on what they could do to prepare for the possibility that we are hit by one of the resultant tsunamis. Many thoughts raced through my mind, and...
If you're like me, you were disappointed when NASA cut their human space flight program. No longer could children and adults in dead-end jobs dream of someday walking on the surface of the Moon or drinking floating globules of water through a straw. Homo sapiens as a species are still making it up there, but I will never be one of the chosen ones.
