How Molecules Became Machines: 2016 Chemistry Nobel Prize Winners
Arden Jansen 

There have been huge advancements in the chemistry field over the last 70 years. In 1959 scientist attempted to build molecular machines. They were not able to complete the task. Later, the University of Strasbourg attempted the same task. They were able to use prior knowledge of how molecules bond and reasoning to complete the job. This experiment was led by Sauvage from the University of Strasbourg. 
Sauvage had many trial and error situations when attempting the experiment. He started by changing the natural affinity by devising a system to link two ring-shaped molecules together. He did this by using a copper ion. This was a big step because they were able to do this without destroying the molecules agility. This fundamental research was crucial to the creation of nanometers made of molecules.  
In 1991, Northwestern University’s professor Stoddart made advancements from Sauvage’s attempt. The one advancement that he made was mounting a ring of molecules onto an electron that would serve as the axle. Then when heat energy was applied, the molecules revolve back and forth on the electron track. The team had a lot of fun with the technology. One thing that they did with the technology was building an elevator that could raise 0.7 nanometers above the starting surface. The work by Stoddart was worthy of a Nobel Prize that was awarded in 2016. 
There are many advancements that will keep being made to the fundamentals of these tiny machines. Interesting enough, an association is France is hosting the first ever nanocar race to try to keep the tiny machine research alive. So many teams were interested that they had to push back the date. These tiny machines will possibly lead to a whole new way of living because of the incoming inventions. An example of one of these inventions is a new way to store energy. This can be crucial as technology keeps advancing and the way of living becomes more and more different.

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 ...

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 ...

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...
