HON CHEMISTRY: How’d you like writing writing nuclear equations to represent radioactive decay? Maybe a tad bit easier than writing chemical equations? Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. Not nearly as bad as polyatomic ions?!?
Great discussion of half life! Do you need a formula for the problems or can you think through them?

There is a wall underwater in Germany that seems to be man made. It goes for about 1 kilometer and has a total of almost 1 700 rocks connected to each other. The heaviest stone weighs over 11 000 kg and radiocarbon dating shows that this was accomplished aver 10 000 years ago; meaning no modern technology. This is wall is what is believed to funnel Eurasian reindeer allowing them to be easily killed ultimately going extinct.

Scientists have developed a new device that would make it possible for amputees to feel temperature in their prosthetic arm. By placing sensors all over the hand, it will allow people to feel changes in temperature, and help to tell the difference between warm and cold things, or if something is alive or not. Amputees will be able to feel what they are touching finally, which will be helpful in many situations.

Scientists have been researching the immune cells that cause allergies. They have found that certain antibodies that help fight off infections are also the ones causing allergies in many people. These antibodies have stopped making a certain protein, and that causing people to have allergies.

Scientists have been researching the reasons that dogs wag their tails. They have discovered that a dog wagging its tail is not always happy, but is trying to communicate something to the owner. They discovered that if a dog wags its tail right, the dog is interested, but if the dog wags its tail left, the dog is uncertain or worried.

In January 202, a group of researchers made an attempt to explore a floating ice off the coast of Antarctica. They made a 600 meter deep hole in ice and put a submarine in the water. One of the researchers, Britney Schmidt, started observing from the camera of the submarine what look to be glistening stars attached to the icy ceiling above. As the submarine got closer to the animals, called anemones, they started crawling into small holes in the ice. This animals have learn to make this cold, dark water their home. This creatures usually live on the seafloor and they sprout from rocks or root in sand. In this environment, they burrowed themselves in the ice. Due to the ice shelves, many thought since it cut off sunlight, the waters would most likely not sustain life cause it could not photosyntheses. This discovery is lowly emerging and are clues that more life may be under this blocks of ice.
