Why not throw

 nuclear waste

into a

volcano?

Nuclear waste is the material that nuclear fuel becomes after it is used in a reactor. It looks exactly like the fuel that was loaded into the reactor.

Once we know what nuclear waste is, we know it's very radioactive and dangerously toxic. As we all know, volcanoes are not closed systems; they have two exits, through the pipe up to the surface, or down to the magmatic chamber. People think if we throw all the nuclear waste into a volcano it will just simply disappear, but that is incorrect. It will eventually come out through either of the two exits I mentioned before.

 If the volcano is active, it will go out to the surface contaminating most of the atmosphere. This will not only affect the atmosphere but it will also damage the oxygen we are all breathing in our daily lives. This can make many animals suffer and many problems to human beings. Like for example having more probabilities to get cancer or to be born with any kind of disability.

If the volcano is not active, the nuclear waste will go through the inside of the earth damaging many ecosystems. Contaminating the plants which will interrupt the photosynthesis in a negative way, and also contaminating the water were many species of animals drink off, and the soil were many insects and also some animals live in.

So the answer to my question is, NO you cannot throw nuclear waste into a volcano because it would be a huge disaster in our society.

can they sweat dogs by tongue?

During summer's dog days, her wet tongue freshens them both as we our sweaty armpits. But, luckily for the dogs, their tongues not perspire really.
Animals with little hair in the body - such as humans, horses and some species of monkeys - cool when sweat evaporates from your skin. For species with long hair, like dogs, sweat would be like putting a coat soaked. For this reason, dogs take the tongue and Pant to cool.
Energy, in the form of body heat, is needed to evaporate the liquid from the surface of the skin or the tongue, explains Jack Boulant, a physiologist heat of the Ohio State University, when the heat evaporates moisture from the surface, the body temperature drops.
After a few years, scientists have discovered that dogs, the system to more regulate internal thermostat, reacts to the heat by pumping warm blood to the tongue, opening the salivary glands and causing a rapid breathing and shallow. As the hot air flows through the trachea and the tongue, help to evaporate moisture, which removes heat from the blood of the dog.
In addition to lower body temperature, this process helps to cool the brain. Blood circulates through the nose and tongue and coldest reaches the brain, which keeps the body which regulates the heat at a temperature lower than the rest of the body. The cooling system works also for races with the short beak, as the Pekingese, which has smaller snout and narrower air passages.

18. IT IS SAFE TO EAT A GENETICALLY MODIFIED FISH?

You may soon be eating genetically modified fish without even knowing it.

The first genetically modified animal intended for the table has been approved by the U.S. Food and Drug Administration, and the agency is not requiring the company who makes it to label the fish as genetically engineered. 

The AquAdvantage salmon has been genetically modified to grow faster than conventional salmon.

The animal is made by introducing a piece of recombinant DNA — a type of DNA that's formed by merging the genetic material of different organisms — into the salmon that makes it grow to market size much more quickly than no genetically modified salmon will.

The FDA said in a statement issued Thursday that Aqua Bounty’s fish had to meet several requirements to gain approval. Among them, the fish has to be safe to eat, the changing of its DNA can't be harmful to the fish, and that it has to actually grow faster, as the company is claiming.

The FDA has determined that the fish is as 
safe and nutritious as no genetically modified fish.

In that photo we can see the diference between a no genetically modified fish and a fish that had been modified.

Can you shoot a gun in space?

The vacuum of outer space will not be a problem for firing a bullet.  Guns do not need oxygen to work. The "gunpowder" or whatever explosive is in the cartridge that holds the bullet is completely self contained and does not depend on the atmosphere.  It has an oxidizer mixed with the fuel and is perfectly capable of firing in a vacuum.  Even the primer which is struck by the pin of the firearm is completely self contained and will work in a vacuum.

The gun will work (very slightly) better in space.  The bullet will not have to push and compress the air in the barrel as it exits the gun.  Air will not slow down the bullet as it travels, so the range of the gun would essentially be infinite.  It will curve eventually since it will probably still be in orbit, but it will have a different orbit than the gun/person that fired it.  For example the International Space Station (ISS) has an orbital speed of roughly 17,000 miles per hour which is 7600 m/s.  Muzzle velocities range from about 120 m/s to about 1,200 m/s depending on the gun and therefore the orbit of the bullet will differ from the orbit of the astronaut that fired it.  In general firing anywhere in the forward direction of the orbit will result in a more eccentric orbit that will always stay at or above the ISS's orbit.  If it is fired against the direction of the orbit, the bullet may end up dipping into the atmosphere and therefore deorbiting.

There is no need to "push" against anything for a gun to work.  The difference between the mass of the bullet and the mass of the gun plus the person holding the gun will insure that the bullet gets almost all the kinetic energy of the explosive (Even though they both get the same momentum due to conservation of momentum.) However, assuming the astronaut is floating freely in space, if the line of the barrel does not point through the center of mass of the gun+astronaut, the firing of the gun will impart some small angular momentum to the astronaut.

TITAN ARUM

Amorphophallus titanum , known as the titan arum, is a flowering plant with the largest unbranched inflorescence in the world. The titan arum's inflorescence is not as large as that of the talipot palm. 

Due to its odor, which is like the smell of a rotting animal, the titan arum is characterized as a carrion flower, and is also known as the corpse flower, or corpse plant . For the same reason, the title corpse flower is also attributed to the genus Rafflesia which, like the titan arum, grows in the rainforests of Sumatra, Indonesia.

WHY IT SMELLS SO BAD?

As the spathe gradually opens, the spadix releases powerful odors to attract pollinators, insects which feed on dead animals or lay their eggs in rotting meat. The potency of the odor (aroma) gradually increases from late evening until the middle of the night, when carrion beetles and flesh flies are active as pollinators, then tapers off towards morning. It smells to  limburger cheese, rotting fish, sweaty socks, sweet floral scent,  Chloraseptic, and  human feces.

 

DISTRIBUTION

Amorphophallus titanum is native solely to western Sumatra,  where it grows in openings in rainforests on limestone hills. The plant is cultivated by botanic gardens and private collectors around the world.

WHY NOT JUST DISPOSE OF  NUCLEAR WASTE IN THE SUN?

After FYI answered why dumping the world's nuclear waste into a volcano would be a bad idea, our inbox was flooded with readers wondering, "Well, how about shooting it into the sun?"

On paper, this is a fantastic way to wipe our hands clean of all that pesky waste. The sun is a constant nuclear reaction that's about 330,000 times as massive as Earth; it could swallow the tens of thousands of tons of spent nuclear rods as easily as a forest fire consumes a drop of gasoline. And NASA currently has two probes orbiting the sun, so the technology exists to get the job done. Alas, the benefits fall far short of the risk involved.

There isn't a space agency or private firm on the planet with a spotless launch record. And we're not talking about cheapo rockets—last year, the craft carrying NASA's $280-million Orbiting Carbon Observatory fizzled out and crashed into the ocean near Antarctica. It's a bummer when a satellite ends up underwater, but it's an entirely different story if that rocket is packing a few hundred pounds of uranium. And if the uranium caught fire, it could stay airborne and circulate for months, dusting the globe with radioactive ash. Still seem like a good idea?

12:WHY ARE HENRIETTA LACKS' CELLS SO IMPORTANT?

-The Henrietta Lacks' cells, also known as HeLa, are the oldest and most commonly used human cell type used in scientific research. These cells come from an inmortal cell  line derived from some cervical cancer cells taken from Henrietta Lacks, a patient that died because of this type of illness. 

-HeLa is used for the searching of information about cancer, HIV, toxic substances and other scientific activities. these are some examples of why this type of cell is so important.
