Bill Nye The Science Guy, “Atoms” (1997).
Could everybody stop falling into the hoax that the Fukushima power plant has contaminated all of the pacific ocean?
Most of the radiation being leaked into the Pacific Ocean is cesium-134, which has a half-life of only two years. Cesium goes in and out of the body like salt, and has had effect on marine populations near Japanese fisheries, however most of the banned sea food is slowly being made acceptable for public consumption.
The real issue now is that some leaks of strontium-90 have been discovered, which is a radioactive substance that stays in the bones of fish and human beings, however much of what has been leaked is cesium.
Now, I am not saying that Fukushima is not an emergency. It is. In fact, that is what is has been classified as by officials. However, we’re not all going to drop dead in five years from eating a pacific fish yet. The Japanese government is spending lots of money to prevent further leakage of radioactive substance.
But the posts you’ve surely seen going around tumblr telling everybody that we’re going to drop dead from consuming milk, fish, vegetables, etc, are totally false! They are taking what is an existing issue and turning it into a crisis.
Whether most of us want to admit it or not, Tumblr is just as bad a source of information as Facebook can be! Don’t trust everything you read, and don’t trust second party news sites! There are people out there who just want to scare you, or make a sensation.
Tangentially related: the shaming aspect of the hysteria really puts me off, too.
THIS IS WHAT YOU SHOULD BE REBLOGGING AND PAYING ATTENTION TOO, NOT MILEY CYRUS!
It’s such a red herring leap of logic. As if talking about one actually takes away brain time from paying attention to something else. Something else that you may not have even bothered to research properly in the first place.
One half of the humans are female, so one half of the scientists should be female.

This photograph of the surface of a human brain (selected as the grand prize winner) captures the intimate view that a neurosurgeon had while operating on an epileptic patient. “The arteries are bright scarlet with oxygenated blood, the veins deep purple and the ‘grey matter’ of the brain a flushed, delicate pink,” said Alice Roberts, an anatomist and one of the judges, in a press release. “It is quite extraordinary.” - Continue reading at Smithsonian.com.

Almost everyone in the United States drinks some kind of caffeinated beverage daily. Whether it’s coffee, tea, a soft drink or an energy drink, you’re consuming caffeine, and that means you’re consuming these crystalline xanthine alkaloids. This photo is a false-colored image of caffeine crystals taken with a scanning electron micrograph.
This is what snake venom does to blood. I strongly suggest watching through to the end.
I think this would be more informative if they specified what type of toxin it is and if that affects its result on the blood in this video…
Happy 4th of July, American friends! Here’s a little chemistry lesson on where the colors in fireworks come from.

If you make movies that have anything to do with science, please note: Astrophysicist Neil deGrasse Tyson, director of the Hayden Planetarium, pays attention.
Tyson pays so much attention, in fact, that he got James Cameron to fix the stars in the sky in Titanic for the recent 3-D rerelease. On Friday’s Morning Edition, he talks to David Greene about this summer’s big movies and how they stack up, science-wise. You should note that there is some talk in this conversation about what goes on in Prometheus, Men In Black 3 and The Avengers, so if you’re desperately hoping to be surprised, you might tread cautiously.
Prometheus is as good a place to start as any, both because it spends most of its time in the far reaches of space, and because Tyson says he saw it “at 12:01 the morning it premiered.” He notes that the early scene in which the origins of human life are explored is unrealistic in one regard: “The unrealistic part of it is that it’s a humanoid alien planting DNA seeds to seed all of life on Earth. And most life on Earth is not humanoid. In fact, most life on earth is plant and bacterial. So if they were to represent that accurately, it would be some kind of bacterium dropping its DNA into the oceans of Earth.”
My little brother got into outer space and stuff so my step-mom bought him a place mat with all the planets on it. When I first saw it, I was upset, because it was newer and so Pluto wasn’t labeled. I was about to say something when I noticed something…
Pluto is there.
