Sting rays and the science behind them

Sting rays have always been a interesting subject to me as I have only seen them in tanks and I get so caught up in looking at them I usually don't look at the info. Sting rays are flattened fish that are somewhat related to sharks. There have been fossils that date back to 150 million years ago! With stingrays there are not 1 or 2 species but there is about 300 different species in 18 families characterized. When you hear the word "ray" and talking about animals usually it is not the stingray as there are butterfly rays, electric rays, round rays, manta rays, guitarfish, and sawfish. When it comes to production they are live bearing animals. Stingrays are often lead to believe that they are dangerous to humans which they are they have venom tails but are often not lethal. Electric rays wrap their tail around and use electric discharge beach-goers often step on these animals and lead to a painful wound yet no deaths have been reported from a Electric ray. The biggest ray is the manta ray (picture below) and the smallest ray is the short-nose electric ray which is about 4 inches. Rays might be usually called stingrays as they are the most common to see at a aquarium or when fishing but truth is that there are a ton that just don't bite!

How long does a nuke have a affect on a area? Well first let us talk about the nuke in general being made up of either Uranium, plutonium, or Thorium or fusion of hydrogen into helium. Usually Uranium in today's standards the explosion is 10 million times the energy produced by the combustion of a atom with coal. The two isotopes mostly used are U-235 and U-238 U-235 being used .7% of the times of nukes and U-238 being used 99.3%. Using these elements a nuke could last up to 4 months (Including Nuclear Waste). The nuke destroys the body or any living thing in it's radius (Cockroaches being a exception). Nuclear Power is not being only used on Bombs they have been used as Nuclear Plants. US had 109 that were certified and there were about 400 in the world. US gets 20% of it's electricity from Nuclear Plants and Means of Nuclear Energy.

Plasma Weapons? True or Fiction?

The closest to plasma weaponry is in the scientists hands and their process can be summarised as this. In our progress of Plasma we are able to have a ring of plasma for 2 feet. We have not been able to exactly have weapons with plasma inside. To give you a good comparison on the power and heat on plasma. The sun is about 6000K hot and plasma happens to be 6600K and up to 7700K! We have not however made it to go over 4ft and will hopefully work up to that point and beyond. However there has been a lighting gun which has been tested and was a success. Lighting makes the air to plasma and could be considered a plasma weapon but has not been released to use under any circumstance and can only be used by those who are certified. They have tested on many targets and hope to finish their research as the weapon could shock itself and potentially blow up. However Russia has attempted to make a plasma shield over artillery and are testing it on Russian tank shells. That is as far as the US and Russia have gotten to plasma weaponry or plasma in general.

What's your Blood Type

Today I will be talking about blood types and what affect they could have to your body and the difference between each type. There are 4 types of blood each with positive and negative being present (+) or absent (-) this is called the Rh factor which is the 3rd of the antigens that show your blood type. Blood type comes from your parents like eye color it's inherited and it comes from both parent's blood type. You can donate blood to someone and become a blood donor but blood can be given to only certain blood types.

The types of blood can be very rare and very common O+ being more common and can be as rare as AB - Blood can also depend on race or ethnic group.

Donateing blood can same lives and can make an empact on people close to them. The procedure is very simple they will ask if you are eligible to do blood work (18+). When you are having your blood taken just bring a music player with you listen to calming music or maybe talk to the person who is doing the procedure you can also have moral support from a friend. If you have a fear of needles the sure to tell them they will take note.

The many ways of Flu

The flu is a very dangerous disease and has ranged from 3,000 to 49,000 deaths a year. There are 4 types of flu A,B,C and the Bird Flu. Bird Flu being the most dangerous and killing 60% of who is effected. The A flu is most commonly in humans but is also in animals wild birds being the host of the flu. Type B is actually only in humans may cause a less severe reaction than the a flu but is still dangerous. Type C Flu is less severe than A and B and doesn't cause epidemics. To stop these types of flu you may have to get a flu vaccine. There are two ways to get a sort of flu protection you could use a shot from a health provider or get nasal spray. The flu is supposed to not be taken lightly as it takes many life's and makes many more sick.
