A radioactive Bluefin tuna was found off the coast of California this weekend. The tuna is believed to have swam more than 6,000 miles from Japan.  Scientists believe the tuna came from the radioactive shores surrounding the Fukushima meltdown in 2011.  A National Academy of Sciences researcher said scientists are  ”startled” by the discovery.

Though the radiation found in this particular Bluefin was ten times higher than the average, however was still within the safe-to-eat levels established by the U.S. and Japanese governments.

The tuna became radioactive by swimming in contaminated waters and eating contaminated prey like krill and squid.  Scientists originally predicted  the radiation would flush out of the tuna’s system by the time it swam to US shorelines.  They were shocked when the high levels remained. 

We doubt this is the last news we will hear concerning the aftermath of the Fukushima nuclear reactors meltdown. All we can do is hope that Godzilla does not evolve from this mess.

Lights on................Lights off

South Koreans are shocking Americans with their scientific kitsch. I have seen black dogs, brown dogs, tan dogs and white dogs but never have I seen a glowing dog. South Korean Scientists have cloned a dog using a somatic cell nuclear transfer, and this dog can glow. The research being done with the luminescent dog may soon become cutting edge medical research for disease control and prevention.

A dog named Tegon looks like a normal beagle in the light, but under ultraviolet light she glows. The “Glowing Dog Project” cost about 3 million dollars to accomplish, yet the project has loftier goals than simply creating a puppy-night-light.

Scientist hope that by inputting different genes into dogs, such as the one that causes Tegon to glow, they will be able to cure some diseases that both humans and dogs are susceptible to. Scientist next step is to give dogs genes for deadly diseases then try and cure them. There are approximately 268 diseases that humans and dogs share.

“The creation of Tegon opens new horizons since the gene injected to make the dog glow can be substituted with genes that trigger fatal human diseases,” Said lead researcher Lee Byeong-Chun.

The amount of illumination Tegon gives off can now be adjusted by how much of a certain drug is put into her food. Scientist are planning to use this same process to help determine if drugs they are using to “cure” the diseases they give to the dog are working.

In 2005, scientist Hwang Woo-Suk used a somatic cell transfer to clone the worlds first dog, Snuppy.

In 2009, South Korean Scientists led by Lee Byeong-Chun, completed the initial experiment of producing four glowing puppies known as “Ruppys”. Out of the four, two puppies survived, and for the last two years they have been undergoing research leading up to this point where Lee can now turn off the glowing ailment he gave the dogs.

Lee Byeong-Chun says his Ruppys: “Are the world’s first transgenic dogs,” meaning they have genes which are not found in nature and have been engineered.

Using the method of cloning, gene implantation, and experimentation South Korean scientist will try to cure diseases. The process learned by making glowing puppies not glow will now be used in an attempt to cure real diseases. Scientist made puppies glow and then “cured” the puppies of glowing. Now, scientist will give dogs diseases, then try and cure them. The final step in this process will be implementing a cloned-dog-cure on a diseased human.

Tegon is the sole survivor who has given South Korean scientist the success they were looking for. Tegon’s successful cloning, illumination, and anti-glow cure have paved the way for further research with diseases and clones.

Japan’s nuclear reactors have had to stand against tsunami waves and earthquakes; however, Scotland’s nuclear power plant, Torness, is having a problem with jellyfish. The pink invertebrates are clogging up the Torness reactor on Scotland’s East coast. Water from the bay is pumped into the power plant as part of the cooling system. Recently, jellyfish (and lots of them) have gotten caught in the filtration system, which could cause the plant to overheat.  Thus as a preparatory measure the plant was shut down last week.

An Environmental Defense Fund spokesperson from the plant said, “At no time was there any danger to the public. There are no radiological aspects associated with this event and there has been no impact to the environment.” This invertebrate problem has happened before at Israel’s power plant, which was also forced to close temporarily.

This just goes to show how fragile nuclear reactors are, and that the threat can either be very big or very small.

Protest for nuclear energy

It’s been twenty-five years since Chernobyl, and many Americans are now aware of the power nuclear reactors have as they have seen the tragedy unfold at Japan’s Fukushima plant in their own generation. Not all American know that this has happened once before in Russia.

Chernobyl was caused by a faulty nuclear reactor with a crew unequipped to manage the situation, the result was the full meltdown of a nuclear reactor (something Fukushima’s plant managers have not yet allowed to happen). The radioactive core released plumes of radiation into the air and across the surrounding land in 1986.

One crewmember was killed immediately, another died immediately after reaching the hospital, and 28 more people died of radiation poisoning. Russia’s plant in the Ukraine was poised for disaster upon completion. The Soviet reactor design was flawed and the crew trained for its upkeep had nowhere near the experience or capabilities to run it.

Chernobyl demonstrated the power and danger of nuclear energy; it was the world’s first radiation induced deaths. The Chernobyl incident was caused when facility workers were attempting to test and see how long reactor turbines would spin in the event of an electrical cut-off.

Today, the nearby town of Chernobyl is vacant looking like a ghost town still full of personal items evacuees

An abandoned Chronobyl high school pool.

were forced to leave behind. The nuclear reactor of Chernobyl is now encased in cement to prevent further atmospheric exposure to radiation.

The fact that nobody is still in the Chernobyl area is testimony to the immense power contained in these facilities. Many Russia’s are celebrating the 25th anniversary of Chernobyl by protesting nuclear energy.

The same protests are currently happening in Japan where those residences forced to evacuate the radioactive areas are upset that the government had put them at such a risk.

Nuclear power is by far one of the most efficient sources of energy today, but it is also the most lethal. It is impossible to predict a nuclear meltdown, its causes can vary from an earthquake to a routine test, and nuclear energy is unstable energy.

Most people today are aware of the dangers of nuclear energy and if you aren’t you need to do more than type in “Fukushima” or “Chernobyl” Into Google to see the history for yourself.

Someone forgot their coat...

An Explosion at Fukushima

On March fifteenth I posted an article describing the initial damages done by the seventh largest earthquake ever recorded. The disaster did not have just one name: An Earthquake, a Tsunami, and a Whirlpool, are just a few of the natural disasters that struck Japan recently. Yet the current nuclear threat is worst of all.

On Tuesday, at 12:30 p.m., the death toll calculation was 3,373 with 6,746 people unaccounted for. Today, March 17, at 12:30 p.m., the death toll is 5,692 and 9,522 missing.

The waves have subsided, however, much of the country is still flooded. Not all of the once dry land will be recovered, Japan as a whole has shrunken, and as I said before, the county has moved eight feet.

The looming nuclear disaster is all but understood; Japanese officials are keeping its citizens frighteningly un-informed on the goings-on at the nuclear power plants. Many people in Japan do not know where safety lies, nor if their food supply has been contaminated by radiation.

The Japanese government has not yet issued an evacuation for Tokyo. The United States, German, Australian, and French governments are telling it’s citizens in Japan to get out of Tokyo; either to come back to their home country, evacuate to the south, or go west to Osaka. Croatian and Serbian governments are telling it’s citizens to get out of Japan; the Croatian embassy has moved to Osaka.

Tokyo is 170 miles away from the affected nuclear plants in Fukushima. That distance is not enough to dilute the plume of nuclear haze being carried by wind over the county. The nuclear plume will eventually reach the United States west coast, by then the cloud will have been diluted down to a safe amount of radiation.

“Health and nuclear experts emphasize that radiation in the plume will be diluted as it travels and, at worst, would have extremely minor health consequences in the United States, even if hints of it are ultimately detectable. In a similar way, radiation from the Chernobyl disaster in 1986 spread around the globe and reached the West Coast of the United States in 10 days, its levels measurable but minuscule” (Broad, William). A statement in yesterdays New York Times.

It is very hard to find out information on what exactly is going on inside of the nuclear plants, and even harder to understand for those of use who are not scientists.  I have bullet pointed the most consistent “facts” I could find.

  • Inside of the plant a team of workers is trying to prevent a meltdown. The workers job has been deemed “A suicide mission”.
  • The workers must keep the exposed fuel rods cool.

Fuel rods: Nuclear fuel rods are the most dense source of energy available today. If these rods get too hot, they will meltdown, causing an explosion. A theoretical meltdown in Japans plant’s could trump Chernobyl in terms of radiation. Japan has an advantage seeing as there is a chance to evacuate the areas that could be affected. Death and exposer could be minimal with a preemptive evacuation as some governments are already issuing.

  • The Japanese military is assisting those inside the plant. Helicopters are being used to drop sea water on the exposed fuel rods, and soldiers were firing water cannons into the flames. The water cannons have since been shut off.
  • The 800 plant workers have been cut down to 50 heros who will give their lives to the nuclear containment effort.

There is a lot of information about the nuclear reactors on the news. One channel tells me that a plant in Fukushima is on fire, whilst the next says the fire there is out. It is a safe assumption that the situation is absolutely unstable, and I hope with the combined efforts of the 50 heros, Japanese military, and foreign aid the situation will soon become stable, yet current information tells me a speedy recovery is unlikely.

As I said before, give thought and compassion to those affected by disaster, and to those to whom it is seemingly looming.
