Why is radiation bad for us but useful at the same time?
By: Bell Muthukumaran

Radiation is used by tons of people on a day-to-day basis, at the same time, it hurts a lot of people,but why? Radiation happens when the nucleus of an unstable atom decays and starts releasing ionizing particles. If these particles come into contact with organic matter, such as human tissue, the radiation can cause harm to you, it can cause cancer and it can even lead to death if radiation levels are high enough. Although all of that information is true, don't be alarmed, that is only if radiation is misused or if an accident happens, such as the Chernobyl incident in 1986. Medical treatment, nuclear accidents, and the people that work at the reactors' environment can all be sources of radiation poisoning. Radiation is used all around us but it is handled safely.

                                                                                                        Something that is scary to think about is the fact that there is no cure to radiation but there are certain barriers that can prevent exposure to it and there are medicines that can remove some of the radiation. Damage to cells by radiation is irreversible so that's why even though you protect other parts of your body while taking an X-ray, you don't get them frequently. There are many ways that radiation is measured such as, Grays, Sieverts, Rems and Rads. Today I will talk about Rads. So these are the amounts of rads and how dangerous they are, 
  • Below 30 rads = Mild symptoms
  • 30 to 200 rads = Person may become ill
  • 200 to 1,000 rads = Person may be seriously ill
  • Over 1,000 rads = Lethal
Why is radiation good? Radiation is good because it is used for a number of things, one of them being radiology. Some ways they are used are X-rays, CT scans, ultrasound etc. Radiation therapy can even help people with cancer because they will make the radiation damage the cells so they die and cannot multiply. Although that is an option for cancer treatment, it has some side affects that can be major such as hair loss, skin damage, fatigue etc.

I think that this field will advance in many ways because people will probably figure out how to reduce some of the side affects for cancer treatment with radiation. We will also probably figure out a way to make the work conditions of those who work in nuclear reactors and factories better so that they have better health than they do now. We do have to figure out a way so there aren't as many deaths by radiation. We should also figure out a way to maximize the amount of efficiency in radiation so that we use less of it, but we get more out of it.

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Mahar-ullah Shahminah- Molecular Gastronomy

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
