When we consider nuclear energy, we remember how bad nuclear disasters have been, and we think of all those terrible nuclear weapons It’s easy to see why so many are opposed to nuclear energy. But in the midst of our climate crisis, nuclear is one of the best and the safest green energy sources we have available.
But how can it be so safe?
Well, here’s an interesting fact: among major energy sources, nuclear is the one that releases the least amount of radiation into the environment. Of course nuclear leaves behind toxic nuclear waste, but that’s managed and stored…
The morning of September 29, 1982, was a difficult one for twelve-year-old Mary Kellerman of Chicago who was struggling with symptoms of the common cold. She was given an extra-strength Tylenol capsule to relieve her pain. She died shortly after.
Also, on that day, 27-year-old Adam Janus passed away after taking Tylenol. Janus’s brother, Stanley, and sister-in-law, Theresa, took Tylenol from the same bottle. Stanley died later that same day.
Nurse Helen Jensen was the first one to link the Tylenol to the deaths. Upon arriving at the Janus residence, she recalls, “I counted up the pills and saw six…
That’s my bunny. For some reason, I have noted that she was very on edge last night, and very early this morning, a magnitude 3.5 earthquake struck not ten miles from where we live.
It’s not the first time this happens either — the night before the last noticeable earthquake, she appeared to be frightened of something.
Is there anything to this other than pure coincidence? Well, it’s hard to tell.
While it is well known that animals can sense an earthquake minutes before it hits, the millennia-old belief that they can detect one a few days in advance has…
Algae, when coupled with AI-equipped bioreactors, can capture carbon up to 400 times better than trees. These ancient microorganisms are responsible for at least half the oxygen in the atmosphere.
With this in mind, many, from startups to coal power plants, have pursued algae to remove carbon from the atmosphere.
Some have even theorized that if we add nutrients to the oceans, algal blooms could take up enough carbon to neutralize our emissions.
But currently, the focus is on bioreactors. A bioreactor is basically a tank designed to grow algae.
Many companies are already growing algae for an array of…
North Korea is quite a strange place. Many Americans have visited the Hermit Kingdom — and while one certain basketball player managed to get away with saying “Marshal, your father and grandfather did some fucked-up shit” to Kim Jong Un’s face, others have received far less leniency.
We hear a lot about North Korean defectors — they are, after all, the most qualified to inform the free world about the state of things back in their homeland. What we hear little about are the stories of the soldiers who defected to North Korea.
There are six American soldiers known to…
Ah, chlorophyll, that lovely green pigment we see everywhere — the reason why plants are green. It is a pigment used by plant cells to absorb light for photosynthesis, but why exactly is it green?
The way a pigment works is by absorbing all color wavelengths and reflecting the one we see. For example, a blue pigment absorbs red and green light but reflects blue. Similarly, a white pigment reflects all wavelengths and absorbs none, while a black pigment absorbs all wavelengths and reflects none. Chlorophyll absorbs blue and red light but reflects green.
Plants use energy from light to…
We’ve heard of many nuclear power plant disasters. Fukushima, Chernobyl, Three Mile Island are some names that come to mind. These seem to leave an impression — but what happens when a nuclear reactor melts down? Does it explode? Is it anything like a nuclear bomb?
Well, to understand why a nuclear reactor meltdown is very little like a nuclear detonation, we first have to understand the mechanism behind controlled and uncontrolled nuclear fission.
When a neutron collides with an atom, the atom becomes unstable and splits. When the atom splits, it releases energy, radiation, and more neutrons. Those neutrons…
Can plants remember? This seemingly trivial question makes quite a few scientists very angry.
Most of the scientific community rejects that plants can reveal any resemblance to the behavior seen in animals with nervous systems.
Despite this, Dr. Monica Gagliano, associate professor at the University of Western Australia, decided she would test whether or not plants had the ability to remember. She would try this on Mimosa pundica (otherwise known as touch-me-not), a plant that folds its leaves inward when disturbed.
In her study, later published under the name “Experience teaches plants to learn faster and forget slower in environments…
Out of everything the world is running out of, its sand is probably the least obvious. With all the deserts and beaches we have, you’d be forgiven for thinking it is in plentiful supply.
As it turns out, the sand that can be used for most applications is extremely limited. Most of the time, desert sand simply cannot do the job.
From concrete and asphalt to glass and computer chips, sand is nearly everywhere. Even paper and toothpaste require some sand during their manufacturing.
But concrete is where most of the sand goes. This is thanks to the worldwide tendency…
It was late October 2007 when the North Korean cargo ship Dai Hong Dan was sailing off the coast of Somalia. It had already delivered its cargo and was sailing back — but those were dangerous waters.
The ship was boarded by seven armed Somali pirates who were disguised as guards. The 22 North Koreans aboard were held hostage as the pirates sent the ship out to international waters and demanded a ransom of USD$15,000.
The North Koreans, despite their surrender, managed to put out a distress signal, which was picked up by the American destroyer USS James E. …
