Bill Nye slammed religion recently with a video saying that teaching creationism was "destorying the minds of our youth". He firmly believes that only evoultion should be taught to youth, as there is scientific evidence for it. According to Bill Nye, "the fact that things evolved is indiputable and should be taught as such."
This is obviously showing what we talked about in Chapter One, evolution.

There has been new findings on the protein called "clathrin". Not only does clathrin transport materials, but it also is important in cell division. This new discovery may lead into how deformities in chromosome segregation is affecting cancer. Proteins are found in chapter three section two. This article was posted on September 10, 2012.
Researchers have found that roadblock can be a new way to prevent the alzheimers disease. if they can block the transport pathway through brain cells they believe it will be a next step to stopping alzheimers. the two main agents involved in the inception of alzheimers are the amloiyd beta precurser protein and the beta secretase enzyme. they take different paths through the brain and it is found that when they meet up it sets off alzheimers.
Researchers have found mutations in a gene that stops several essential amino acids being depleted. This deficiency causes a rare form of autism that could possibly be treated with a dietary supplement. The children were tested after receiving the supplement, their blood levels of amino acids were normal.

Columbia researches have come up with an idea that they can transform cells from the intentness to insulin.They have always veiw stem cells as the only way now this development proves other wise.
A team of researchers managed to sequence the first complete complex carbohydrate biopolymer, or glycosaminoglycan. The first carbohydrate biopolymer sequenced was taken from bikunin, a proteoglycan (a protein where one single carbohydrate biopolymer chain is attached). If looked into further, understanding the carbohydrate biopolymer could lead to further understanding of evolutionary differences and how carbohydrate chains respond to disease and injury. The source date is October 10, 2011.
Scientists have recently made explorations into the biological clock and the control of neuronal activity. They found the gene that controls the biological clock to be Ir, they surprisingly found that Ir is not only the output of the biological clock but it also can send feedback to the core clock. This feedback helps the clock to maintain working well. Source date: September 25, 2012
There has been a study that has linked electromagnetic waves to the unzipping of DNA. Scientist now believes that cell phones, Wifi hot spots, power lines and electrical appliances are breaking the hydrogen bonds on are DNA. This can damage DNA severely and cause many genetic disorders. This relate to our class because we have learned about DNA and its weak hydrogen bonds.

Esther Verheyen,a sciencetest found out a protein,kinase, can be duplicated to stop the over growth of cell tissues, it stops the growth of yorkie cells otherwise known as "yap"in humans. Which might be able to help stop cancer.
Nutrition's have noted that the presence of carbohydrates in just the mouth alone gives a burst of energy to athletes and or those in need of an energy boots w/o the need to ingest. This is because the carbohydrates trigger a response to the brain. This relates back to chapter 2 section 3 when these carb-filled drinks transport stored energy within complex organisms.
New ways of obtaining protein with out all the red meat and fats have come to light. These days more and more people are becoming vegan so there is a need for protein substances that don't come from consuming the usual meat product. They found that vegetables like: avocado, broccoli, spinach, kale have high amounts of protein. Also, lentils, beans,nuts,seeds,non-dairy milk and grains have high amounts of proteins.

Researchers at the Mayo clinic have discovered a new enzyme that destroys one of the proteins that builds up in an Altzeimers patients brains.The name of this new enzyme is BACE2, and there is one that is almost the same as itself but it has the opposite reaction. With this discovery they can infer that mutations in this protein might give you an increased risk of Altzeimers. However they don't know that yet, and are going to start experimenting with BACE2.

At UC San Diego chemists have developed a method that allows researchers to have a better understanding of the biochemistry of proteins. This will allow better antibiotics to be made and scientists to be able to track proteins in living cells.
There is a project over in Europe where they plan to reverse engineer the human brain by 2023. This will be done by creating a detailed simulation of the entire human brain in a supercomputer. This in essence would be emulating the biological processes in the human brain. The project is two of six that might receive one billion euros from the European Commission. If it does it will be called the Human Brian Project (HBP). This is an extremely interesting article and there also is a TED talk about it.
The article was published on 02-22-2012 by the journal nature.
The structures of bacterial proteins have revealed one of the biochemical secrets that enables bacteria to avoid the effects of antibiotics.Multi-drug tolerance begins with a protein kinase molecule called HipA, which forces a few bacterial cells into dormancy. Eventually, these cells awaken to begin growing and starting the cycle of infection all over again. The main point of this atricle is scientists have found a protein that reveals secrets to stopping multi drug tolerance. This is a very big step in our medicine department and is also a very interesting article. This article was in a paper published Sept. 20, 2012 in the journal Cell Reports at Duke University School of Medicine.
Protein-bound polysaccharide K (PSK) is an anticancer agent used for adjuvant therapy against gastric cancer. Scientists ran an experiment and found that using this polysaccharide in combination with oral chemotherapeutic agents is increasing patients' chances for survival.

It was once believed that only about 1% of our genome had gene regions that code for proteins. This was recently proven wrong, and that we actually use about 80% of our genome. Knowing that there is much less wasted space, biologists believe that they will be able to better our understanding of how several human diseases are developed and behave. This article was posted on September 6th 2012.
The salt marshes around the world take the heat-trapping carbon out of the air. However, if the sea level rises more than 1mm per year and the plants in the marshes get swamped, then the stored carbon beneath will be released. Presently, sea levels are rising at about 3mm per year. By this rate, the salt marshes will be swamped by 2050 and the carbon will no longer be absorbed. This will contribute a rise in global warming.

Enzymes are made into pills breaks proteins down. One capsule allows a person to digest proteins, carbohydrates, and fats. All in all, the pill helps digestion moves smoothly for a person.
Enzymes are protein molecules, that play a role in every single biochemical activity in the body. Enzymes have over of different functions, like digesting food, activating the brain, increasing cellular energy and repairing all organs, cells and tissues. They are divided into two main groups: metabolic and digestive. Metabolic enzymes create energy, digestive enzymes are known for breaking down foods.
Recently the University of Stanford found that the protein DUSP6 can be beneficial to the human body. The university fingered a protein that interferes with the capacity of an important class of cells in the immune system to respond to the presence of foreign substances, like cancer and other invading cells. The university also found a compound that restores those cells' responsiveness by inhibiting the DUSP6. The website is http://medicalxpress.com/news.
The biological activities of the interactions of oxidized low-density lipoprotein (LDL) and macrophages are due to the content of lipid oxidation products and apolipoprotein modification by oxidized phospholipids. The aim of this study was to determine the role of short-chain oxidized phospholipids as compounds of modified LDL in cultured macrophages.

Chemists at the University of Warwick, in collaboration with researchers at Cornell University reported the discovery of an enzyme that catalyses an aromatic nitration reaction. This enzyme could potentially help to cut down the use of the highly corrosive chemical nitric acid.
Huntington's disease is known as an incurable disease caused by the degeneration of nerve cells that impairs a person's ability to function. Recent research shows that two new proteins, KMO and JM6, both caused the disease to slow when tested on fruit-flies and rats. JM6 also prevented memory loss and could be used to cure Alzheimer's disease as well.

Misfolded proteins can cause various degenerative diseases such as Huntingtons.These are caused by progressive neuron loss in the brain. In this study, scientists have discovered 21 different proteins that bind to ataxin-1 and 12 of these proteins enhance the misfolding of axtatin-1, while 9 of them prevent the misfolding.
Researchers at the Fred Hutchinson Cancer Research Center in Seattle have found parts of male DNA within the brains of females that did not have any neurological diseases and they say it's common. They found that 18 of 26 women had traces of male DNA spread throughout their brains. This wasn't a complete shock because this male fetal DNA has been found in other organs of females such as their liver, lungs, and hearts. The main question is how the cells could have gotten through the "blood-brain" barrier which is a barrier that protects the brain from pathogens within blood. The researchers found in a follow-up study that women with Alzheimer’s had less foreign DNA in their brains so this DNA could be a source of protection from the disease but they say that the data and results are too premature to be conclusive. Other evidence also shows that fetal cells can affect the risk of cancer and other diseases.
This relates to chapter three section on on nucleic acids.
As of 2008 there were 6 children killed and over 300,000 reported with illness from dairy products containing leather proteins. The indrusties use the leather to increase the protein in their milk products. Once investigators found out about the protein in 2009 they started to do random check ups and was shut down due to toxins.
Your body uses enzymes for numerous reasons, one of which being to digest nutrient from food eaten. If the pancreas doesn't put out enough enzymes, then it becomes enzyme starved. This is a major problem because for example, cellular metabolism includes respiration with oxygen. If there it can't use oxygen, it tries to use glucose instead which is the beginning of cancer and cancerous cells come into play.
Researchers have found a new way to identify the proteins secreted by certain cells. The work is important because if the can understand the proteins they can understand what commands the cells are giving because cells communicate through secretion of proteins. The researchers do this by isolating the secretory pathways in cells which contain the protein.

Not everything about exercising is good for you. When you work out you are using your muscles which are made up of proteins. Therefore, in some way you are damging your proteins and proteins are wha repair muscles. Studies have confirmed that when you exercise there is a lack of oxygen in your body for that period of time and that causes mutations in mitochondrial DNA. This relates to what we learned about proteins in class.
This article explains that scientists have found the gene that controls the spots and strips on a cat. This discovery may allow scientists to create the color and stripe pattern of a cat by mutating the DNA in the future. This and other discoveries could allow for customizing what you want your cat or pet to look like in the future.

A group of scientists in New Zealand have engineered a cow that produces hypo-allergenic milk that is safe for infants with allergies to milk. A cow can be genetically engineered to lack beta-lactoglobulin (BLG), a protein that causes an allergy in 1.5% of all toddlers. The team began expirimenting with RNA "interference" techniques back in 2006, and started expirimenting with sheep milk, which was effective. The gentically-engineered cow is only a calf, so they won't be able to determine any affects on the cow until it reaches adulthood.
