FDA Cracks Down on Illegal Supplements
According to an article on comcast.net News the FDA is cracking down on the manufactures of supplements made to enhance sexual activity, increase weight loss, and those used for body building. According to the FDA the manufacturers of these products are incorrectly labeling them trying to cover up ingredients that they contain that can cause serious side effects including stroke, organ failure and death. FDA commissioner Margaret Harnburg says "the manufactures selling these tainted products are operating outside the law." The manufactures are supposed to ensure that these products are safe and they do not currently require FDA approval. The FDA is currently trying to get these companies to pull the products from the market; the government does not currently have the power to issue a recall. The FDA however is issuing warnings about the products to create awareness and have stated that the companies could face criminal prosecution.

Slim Spoils for Obesity Drugs: Pharma Struggles to Find Safe Treatments
Contrave, developed by Orexigen Therapeutics, based in La Jolla, California, and co-founded by Cowley, director of the Monash Obesity and Diabetes Institute in Victoria, Australia, is a combination of two medications. One is an anti-depressant, the other is used to treat alcoholism. Together it is said that they boost the activity of a brain circuit called POMC pathway, which reduces hunger. The final decision on approval is expected early next year.
Studies have shown that even with this drug only a 8 percent decrease in body weight was reported after 6 months. It says that the next drug that is likely to face the FDA will target metabolism.
In my opinion, there should not be any drug for obesity. It seems that there is a drug prescribed for everything these days, I think the risks are to great to use unless there are no alternatives. Our society needs to change if obesity rates are to decline. I recently read that the food additives used today are actually designed to addict us to them, obviously attributing to obesity. It seems all food in the market is bad for you in some way. The FDA needs to change what food is readily available to our society and people need to make healthier choices.

Insights Give Hope for New Attack on Alzheimer’s
I found this article to be an extremely interesting. I find Alzheimer's to be a devastating but fascinating disease, I would love if one day we can find a cure or some form of medication to prolong the disease. It’s a horrible disease to watch your loved one go through, so I hope this is a successful new breakthrough.

Humble Honey Bee Helping National Security
“Bees are at least as good as sniffer dogs but are cheaper and faster to train, and available in much larger numbers. It is dependent on the specific odor, but bees can detect some odors that are present in parts per trillion - that’s equivalent to detecting a grain of salt in an Olympic-sized swimming pool,” says Dr. Nesbit, a research scientist at Insentience Ltd.
The process of training the bees is a simple one. They are placed in a holder where different odors are passed over them. Every time they smell an odor a small dose of sugar syrup is administered to them and they stick their “tongues” out to receive the award. After a few rounds of this, the bees stick their “tongues” out after smelling the odor without a reward being present. Once trained, up to 36 bees are loaded into a hand held sensing device. The bees can be trained to detect the same odor, or smaller groups of bees can be trained to detect different odors within the same device. The bees are exposed to a constant stream of clean, filtered air until a sample of air from an area requiring testing is sucked into the machine. An optical sensor records any bees extending their “tongues,” which is then interpreted by software. Based on a statistical population of bees, a simple odor present/absent response follows. The whole detection process takes around six seconds.
This article really caught my eye just because it's bout bees! Who would've thought bees could be used for anything other than producing honey (or causing allergic reactions). I feel that this could really become useful in the future once perfected. It's easier to train hundreds of bees than dogs!

Pain Free Mammogram: Digital tomosynthesis
According to an article in Science Daily radiologists have recently devised a better way to perform a mammogram. The digital tomosynthesis, is helping find cancer as small as 2 millimeters. This machine uses an xray tube that moves around the breast at at least 11 different angles taking multiple images.A computer then puts the information together to create a 3-D image. A traditional mammogram only used 2 angles and can be difficult to read due to dense breast tissue that looks similar to cancer. Elizabeth Rafferty, a radiologist at Massachusetts General Hospital states, " I think for many radiologists the prospect of interpreting a mammography is very scary." comparing it to Where's Waldo she says ".....I'm trying to find the thing I'm interested in but it looks like everything else in a sea of normal structures." Another benefit of this new method is it uses less compression, making it less painful for the patient.

Newfound planet stirs old debate
Astronomers who have spotted three large planets orbiting around a single star have just found another one, that seems to be larger than Jupiter. It seems to be very close to the star HR 8799. The astronomers are wondering how all four planets were formed. The newly-found planet lies only 130 light-years from the Earth, and 14.5 astronomical units from its sun. "The planets orbiting HR 8799, with masses estimated at between five and 10 times that of Jupiter, form a scaled-up version of the planets in the outer solar system, according to codiscoverer Christian Marois of the Herzberg Institute of Astrophysics in Victoria, Canada, and his colleagues."
The astronomers are also wondering how the gas giant arised. The astronomers believe that if the other three planets were formed right where they are they must have been formed by gravitational instability, and the new planet is believe to be formed by core accretion. There is also a belief that the planets have migrated after they were formed. They are still discussing this issue, and are hoping to find out how these planets were formed.
I found this very interesting. Especially how new planets are continuously found in space. It makes me wonder how many more are out there that have not been found yet, and how many are forming at this very moment.

Microbe that can use arsenic as nutrient found

Arsenic and Old Bacteria
According to Biology News Net, research began on this subject when Mono Lake in California was examined closer. The lake has high levels of dissolved arsenic concentrations, and it is believed to have been formed from neighboring volcanic eruptions. The study done by Lawrence Liverpool National Laboratory, which was led by NASA, found that a bacterium isolated from Mono Lake can substitute phosphorus with arsenic to sustain its growth.
The six building blocks of living matter are oxygen, carbon, hydrogen, nitrogen, sulfur, and phosphorus, which are all made up of nucleic acids, proteins, and lipids. These new studies show it is possible to replace one of the building blocks of life with something that is considered a poison. That shows that it is possible for organisms to live and survive on non-typical elements, so scientists have used this idea for the subject of life on other planets.

Scientists Find Fountain of Youth ... in Mice
The enzyme telomerase was used during this experiment. It is an enzyme that makes small units of DNA that seal the tips of chromosomes. They act like the plastic caps at the ends of a shoelace, preventing chromosomes from fraying and genes from unraveling. When scientists increased levels of telomerase in the mice, their organs began to rejuvenate. Harvard stated that shriveled testes grew back to normal and allowed the mice to be fertile again along with other organs that recuperated from their degenerated state.
In humans, however, this experiment could hold extremely different results. The main problem is the fact that the enzyme telomerase stops generating in humans so that cells do not over replicate themselves causing cancer; the risk of cancer would dramatically increase.
I found this article extremely interesting. It is amazing how far along scientists are coming on a day to day basis. Imagine what this experiment, once made accurate for humans, could do for our society today? It sort of reminds of stem cell research except this experiment is a lot less controversial. Obviously this is just a small step in this research, but at least it's something!

Blueberries, a Very Healthy Fruit
I knew that blueberries were healthy and good for you, obviously because any fruit is. I wasn't aware of all the antioxidants and fiber they have. It's interesting that Native Americans used them to treat coughs. If more people knew this, then maybe there wouldn't be such a high need for cough drops and medicines. I also think it's kind of interesting that there is a whole month dedicated to blueberries.

Studies About HIV Antibodies
Some of the earliest and most abundant antibodies that are available to try and fight the infection cannot actually “see” the virus until it has already invaded, and is too late. These scientists have done a series of biochemical and crystallography experiments which showed them what specific molecular structures different types of antibodies need in order for them to hold an effective defense. Now that it is known what kind of structure is needed, researchers have a better understanding of what an immune system needs to have an effective defense against HIV.
The subject of preventing and treating HIV/AIDS is one that is very important and urgent. These studies are a big milestone in the process of figuring out this disease. I think it is great that scientists are getting farther towards a way to help people who have been infected with this dangerous illness.

May Beer Have Helped Lead to the Rise of Civilization?
“Beer is sacred stuff in most traditional societies,” described Bryan Hayden, archeologists at Simon Fraser University in Canada. According to LiveScience.com, beer could have possibly led to the rise of civilization. Research has shown that Stone Age peoples would domestic cereal grains, not to fill their stomachs, but to lighten their heads.
This whole idea came about due to the fact that there was a good amount of work that had to be done to make the grains edible enough to eat and this would be done usually for a feast of some sort. The feasts were important community gatherings and having beer sparked interest to the other people.
"It's not that drinking and brewing by itself helped start cultivation, it's this context of feasts that links beer and the emergence of complex societies," Hayden said.
Beer was usually made to impress guests, make them happy, and alter their attitudes favorably towards the host. The idea was that the people who held the feast would get reciprocated for their work. For example, they would be invited to someone's feast and get the same hospitality.
Although there is significant amount of evidence pointing to the correctness of this theory, there still needs to be more exploration.
I'm not going to lie, the first thing that caught my attention to this article was the word “beer.” I thought to myself, 'How does beer relate to science?' After reading the article I was quite stunned to realize that this could really be true. It's funny to relate Stone Age people to our society today. Clearly, nothing has changed.

Reducing the Risk of Peanut Allergies
There were researchers in five United States study sites who evaluated 503 infants between the ages of three to fifteen months, who had likely milk or egg allergies, which are factors that are associated with an increased risk of peanut allergy. The infants whose mothers ate peanuts during the pregnancy had blood tests that showed a stronger sensitivity to the peanuts compared to the infants whose mothers did not eat peanuts. The researchers acknowledge that the test results only show that there is a potential risk factor, and once they further the studies, maybe they could develop a risk reduction.
Peanut, milk, and egg allergies are very dangerous, so I think that any kind of research that could maybe prevent them or reduce the risk of developing them is very beneficial. The article said that these allergies are potentially fatal and they are becoming more prevalent. These studies may have seemed like a small step, but I think it was an important step towards reducing the impact of these allergies.

How the Ozone Layer is in Jeapordy.
The Ozone layer is a big part of our life in this World. It helps us humans get the right amount of light and energy from the sun(Ultraviolet Rays), without getting harmed. The O3 oxygen is what blocks the Ultraviolet Rays. As well, there are always consequences to what products we make, and how we dispose of our wastes. Chloroflorocarbons (CFC) are what we use in everyday products such as, refrigerators, freezers, hairspray cans, asthma inhalers, and even car conditioners. And they are the problem that will destroy the Earths future. With the amount of these products that we use, we will destroy the ozone layer in a few hundred years. The CFC's are emited into the sky, and when they reach the Ozone Layer, they form a different chemical reaction then the one that is natural occurence in the Ozone (O3). With the normal reaction, (O3 )is split by ultraviolet rays being absorbed, and O2 + O is formed. Normally they would rejoin quickly to form Ozone, but bad part about the CFC's is when absorbed they altar this reaction because of a strong chlorine atom, and forms (CIO) in the Ozone instead of (O3). Now the ultraviolet Rays are flying through the Ozone Layer and we are absorbing harmfull rays. This is a nother demonstartion
North Pole
South Pole
As you can see the Ozone Layer is much thin and the Chlorine levels are sky high, this is going to become a huge threat to us and our wildlife. The Ozone layer is a big part of our living, and many people do not understand that. The era must be started, and there must be some way to cut back the usage of CFC's. If we don't start to help, there will be no future.

Newly Discovered Snub-Nosed Monkey Sneezes in the Rain
According to ScienceDaily, a new species of monkey was discovered in Northern Myanmar. It was discovered during the Hoolock Gibbon Status Review in 2010. They started investigating when hunters started seeing monkeys with prominent lips and upturned nostrils.
The species, Rhinopithecus strykeri,is unlike any other snub-nosed monkey ever reported. It has a a long tail, and black fur everywhere except for around the face and ears. The species is very new to scientists, but when interviewing the locals, they knew exactly what the scientists were talking about. They could tell what kind of monkeys they were because when it rained, the water would get stuck in their noses, causing them to sneeze. It was said that they could be found sitting with their heads in-between their knees when it rained to keep the water out.
Just like the other types of snub-nosed monkeys, this species along with the rest are all endangered due to hunting and new developments.
I found this article very interesting. It is always really cool to read about new species being discovered. It just goes to show how much we do not know about our own planet! (I also thought it was sort of cute, in a weird way)
