Summary: Dr. Daitoku Sakamuro of LSU Health Sciences Center New Orleans and the LSUHSC identified a protein that enables the activation of a DNA-repair enzyme that protects cancer cells from tremendous harm casued by chemo and radiation therapy. The protein c-MYC oncoprotein, can promote almost all human cancers and discovering the cancer treatment resistance may lead to many lives being saved. Researchers also propose that analyzing the levels of c-MYC and BIN1 also serve as a valuable prognostic marker to determine if a cancer responds to an aggressive dose of therapeutic agents. Cancer accounts for 25% of deaths in the US with an estimated 569,490 cancer deaths to be expected las year. Dr. Sakamuro add, " our study will determine how we can re-sensitize maligent cancer cells to conventional DNA-damaging therapeutic agents and how we can minimize unnecessary side effects associated with cytotoxic chemo and radiation therapy.
Opinion: I think the research that Dr. Sakamuri is doing is a really good thing. My granfather had cancer and altough it was detcted early and it didnt do any severe damage, he nor anyone else should have to go through the pain of dealing with cancer or have to see a family member go through it. Its amazing how far we have come in life to keep discovering new vaccines, medicines, and treatments to the illnesses we have today. The fact that a quarter of the deaths in the US are from cancer is pretty scary. Hopefully we'll reach a point where no one has to worry about any type of cancer.

At the University of Montreal and McGill University, scientists have discovered a cellular bilingualism. This means that one neuron, has two functions (two types of communicating messages). That action is known as contramission. There are two types of time scales, slow and fast. This neuron has both. This finding, could help explain other diseases, such as, Parkinson's, depression, and schizophrenia.
I personally do not think that bilingualism is a disease. It is just simply learning another language. It is the same as learning different maths or sciences. To me, this seems like a far stretch for this finding. Although, it is neat that scientists are able to come to this conclusion, by looking at DNA.

Who felt it not, smelt it not
New studies show that people who feel no pain due to genetic inability, also cannot detect odors. The nerves that uncover pain rely on the same protein as those concerning smells to deliver the information to the brain. Three people who posses the inability to feel pain participated in the recent study. Researchers found that they were unaware that they could not smell anything since birth. This has been an important discovery by linking that smell and pain by sharing same delivery of information to the brain.
I think this is very interesting because I too would never make the connection between the the link discovered. It makes me wonder what else could be connected that scientists have not uncovered yet. Hopefully this knowledge can be used to our advantage. If we can find other links as well, a new door of opportunity might be opened for further research. One day maybe this information could be used to help study diseases or other disorders.

A Safer, More Effective Morphine... Coming Soon?
A orphan drug originally used for HIV patients during their treatments has been found, by the researches at Indiana University School or Medicine, to short-circuit the process that results in additional sensitivity and pain from opioid use. Morphine, the gold standard for controlling moderate to severe pain, has given side effects such as reduced respiration, constipation, itching and addiction. Patients also develop a tolerance to morphine which can lead to a complicated spiral disorder. At first opiods were used to relieve pain following surgery, from cancer and at the end of life, but today opiods are used nationally for painful conditions like osteoarthritis and back pain. Morphine may hurt people instead of helping them, this new drug claims to produce a "new pain" to contradict the other pain.
I think these researchers are doing a great thing. Using a substance for morphine could help many people. Sometimes it seems morphine only hurts patients because of the side effects and risks of addiction or increasing the dose. If the researchers succeed they will help many patients feel no pain with out worrying of the side effects or later problems. If this "new yet improved morphine" does not cause more pain by inducing inflammatory responses in the body like morphine does then the medical world will have a great, safer medicine in there hands.

Cruise Ship Infection
My current event is on the outbreak of gastroenteritis on a cruise ship of 2009. It talks about ways to prevent it from spreading. They now discourage sick people from boarding their ship. This disease is also very contagious; even from skin-to-skin contact. It's also spreadable through the air if fumes are breathed in.
My opinion on this is half and half. It is a good thing that they have ways of preventing outbreaks on a ship. The bad side to this is that they have nowhere to put sick passengers besides the nurse office, and then she gets sick. This disease kills about 21 million annually (serious killer). Thanks for reading :)

Self-Strengthening Nanocomposite
The researchers at Rice University have created some kind of material gets gets stronger from repetitive use. This can be compared to how muscles get stronger after work outs. Pulickel Ajayan is a professor at Rice University has created this material. He got this idea from the complex nanostructures and polymers in engineered nanocomposite materials. Brent Carey, a graduate, discovered that more stress mean it gets stronger. He used dynamic mechanical analysis and found that 3.5 million compression made the material 12% stronger.
This is very interesting and useful. The world of science has grew a lot and many new things have been made. This is one of those things that can make the world a better place. A material that can make it self stronger is just amazing. There are so many things that can be used for. I hope this project works successfully and make a difference in the world.

Fish Know to Avoid the Spear
Marine biologists have discovered that in some area where fish are hunted with spear guns they are more wary and they keep away from swimmers. They have observed that these fish are ussually from the areas arround devloped countries. In developing countries, fisshing has stayed at the traditional line and rod method where in other areas they fish with spears, rods and even net to catch a large amount of fish. Scientist measured the fly speed-the speed it takes a fish to swim away- by measurind how fast it took the fish to swim away just by seeing the diver. The fish from developing countries ussually reacted much slower because there arn't ussualy much under water diver hunting for fish.
Opinion
These fish are used to living in parts where there is a lot of fishing, ussually, in highly domesticated and over populated areas. It's curious how as soon as a diver enters the water, the fish quickly swims to the protected area of the water where fishing is prohibited. Unlike in other areas where fish are caught for the days meal, in these areas a very lare amount of fish is caught for exporting to different countries and to be canned or sold in grocery stores. These animnals have adapted to their environment instaed of apandoning a place where they are aware of prepadors, and in this case it's us humans. Even though they have adapteed to their environment these areashave and will always have a smaller ammont of fish than other parts of the water.

Monitoring Coral Reefs
Chris Langdon, along with other scientists from the University of Miami Rosenstiel School of Marine and Atmospheric Science, have recently developed a new tool to monitor the vital signs of coral reefs. The purpose of this tool is to accurately measure the biological pulse of the reefs. Scientists hope the tool will assist in determining how climate change and other economical threats impact the ecosystems. The tool will measure dissolved oxygen production, which leads to measuring the results of the production and consumption of the organic matter within the reef. This advancement is expected to expand the studies in protection of coral reefs.
Coral reefs play a huge role in the world today and are many times forgotten about or simply ignored. 75% of the world's coral reefs are endangered primarily because of human influence. My hope is that this tool will help prove the huge impact humans are having on the coral reefs. Something needs to be done to prevent complete destruction and depletion of the precious and abundant ecosystems. This new too could lead to long-term resolutions needed to protect the coral reefs.

New Targeted Drug Helps Smokers Quit
http://www.sciencedaily.com/releases/2011/03/110317115358.htm
The Academy of Finlands Research Program has been striving to create a drug for the use of smokers to help them quick. The new drug slows down the metabolism of nicotine, which would help smokers cut down the number of cigarettes they smoke. They have found that nicotine is absorbed rapidly through the lining of the mouth but most is absorbed in the lungs. The nicotine then goes into the brain. Once the nicotine reaches the liver, it is metabolised by an enzyme called CYP2A6. The enzyme can help smokers curb the need to smoke.
I think this drug is a great discovery. I think that this may be the best plan for anyone who wants to stop smoking. The new opportunities are advancing from a patch to a pill and going from outward help to internal help. This gives smokers the opportunity to live a healthier more efficient life. In the end, this pill will be a relaxing therapy to smokers who have the urge to quit.

Elephants Benefit From Elder Matriarchs' Experience
http://www.nytimes.com/2011/03/22/science/22obelephant.html?ref=science
Kendall Roberson
Scientists have gained the knowledge that elephants benefit by being led by older matriarchs. A matriarch is the head woman or female in the group. The matriarch is better at locating and scaring off predatory male lions. Elephants with older matriarchs are able to organize and march toward a roar to challenge an assumed predator, more quickly as a united, or "whole" front better than each elephant for itself. Groups with matriarchs of 60 years or over are able to conclude if a lion's roar is a female or a male roar (male lions are far more dangerous), and can react quicker and more productive than groups with younger matriarchs. The matriarchs of the groups live to be around 60 years old and they remain group leaders until they die. Also, the matriarchs have no hearing loss at the age of 60.
I believe that the idea of having an older matriarch is a good thing. Having a matriarch brings a different perspective to the group because a woman can hear and determine different things than a male can. I like the idea of how matriarchs are still group leaders until they die because it keeps consistency in the group. Matriarchs should continue to be the leaders of the groups because they are productive, organized, and it has made the group more defensive to lion predators. Elephants benefit more from matriarchs compared to male leaders due to the organization, hearing experience, and group unity.

Better Biotech Enzymes
Agustin Gonzalez
Summary:
This article talks about a new type of enzymes in the field of Biotechnology. Enzymes are proteins that speed up chemical reactions, So Proffessor Kam-bo Wong and his team in the Chinese university of Hong Kong used this info and discovered new biotechnological enzymes. They are using new enzymes found in the protein of bacteria called Thermophile. It can be used in research in further studies in the field of Biotechnology.
Opinion:
I wonder what these new enzymes can actually do in the field of Biology. I also wonder if these things will even actually do anything in our lives. I heard that making an engine that contain these "new" enzymes, will allow the car to go up to ten times faster. I'm wondering what can you possibly do with a car like that. I mean, you probably wont be able to even go someplace like McDonald's because it probably wont even be street legal. So I actually think this is useless

Weed-eating fish?
There has been a discovery of weed-eating fish. This may help to assit the coral reefs in the world to remain...well here. There are two types of fish: parrotfish and surgeonfish. These fish can help only if the weed hasn't taken over a certain amount. Once past that amount the weed will take over entirely and the coral reef will be lost.
This is an astounding discovery for the preservation of the coral reefs. Due to the low population of the fish they will try to preserve some of them. If coral reefs were gone there would be one less natural beauty in this world. The weed eating fish will be such a great help we may never have to lose another coral reef again. Thanks for reading :)

Cat Allergy? I foresee a cure in your future…
http://www.sciencedaily.com/releases/2011/03/110309182104.htm
Do you have cat allergies? Well, your problems could soon be over as a team of immunologist at the University’s School of Molecular Medical Science has discovered the cell component that causes this reaction. This team is lead by Drs Ghaem-Maghami and Martinez-Pomares. They believe this development to be extremely good, with all the recent asthma attacks in the last few decades they can use all the help they can get in the UK. Recent statistics show that at least three people die every day from an asthma attack over there. When a person has asthma their symptoms worsen as they are exposed to airborne allergens that can come from places like cat dander, dust mites, and pollen. At least 40% of children are allergic to cats, or rather their dander. With their worsening attacks the doctors are ecstatic that they have found this cell component. Along with this information they can continue research to create better products and solutions that can eventually help cure asthma once and for all.
In my opinion I believe this to be a big burden that has just been wiped off the back of humanity. My brother has a minor case of asthma and it is a relief to see that this little problem can be washed away. It is very sad to hear that all these kids in the UK are dying because of this. Some even say that it has reached epidemic proportions in a lot of industrialized countries.

Tobacco Smoking Impacts Teens' Brains, Study Shows
Tobacco is leading cause of deaths in the U.S over 400000 die each year of disease thqt invole with smoking. Major of adults started smoking when they were 18. UCLA researchers wanted to compare brain function in adolescent smokers and non smokers and they found that non smokers I.Q and there brain cells have a greater impct then the teen that smokes . People that start smoking at ages 15 - 17 have a greater percentage to having lung or throat cancer then people who pick up the addication at a late age.
i think teens should not smoke i think cigs are cancer sticks and they affect our thinking capacity. I wish cigs where never invented and we had somthing that really helps us to get off of them

Controlling Skin Regeneration and Skin Cancer
http://www.sciencedaily.com/releases/2011/03/110303132306.htm
This article talks about research found by Fernando Camargo, PhD and the study's senior researcher, and his colleagues that skin cancer and skin regeneration are close in function. The team experimented on a molucule called Yap1 to cause large tumor growth. When Yap1 was suppressed in mice, experimental guinea pigs,their epideral skin cells did not expand and the mice had very thin skin. They also found that more Yap1 aids to thicker skin, but activation of Yap1 led to "squmaous-cell carcinoma-like tumors". More research showed that Yap1 was inactivated by alpha-cantenin, which attachs to the Yap1 and keeps it out of the nucleus, but when squamous carcinoma cells mutate with alpha-cantenin they can get back into the nucleus and cause tumor growth. The alpha-cantenin can tell skin cells whether to grow or to stop growing through the Yap1. This molecular "switch" they found could lead to finding ways to grow skin cells when needed or reverse and stop cancerous cell growth.
I think that this is really neat, that like they were able to find the connection between the growth of cancerous tumors to the growth of skin cells. If this "switch" can lead to easier skin cell growth for people with burns or that are in need of new skin, and then turn around and stop skin cancer cells that's awesome. I would totally agree with further research on this subject, because now more people are getting into tanning and being tan all the time, which can lead to serious cases of skin cancer. So, in this case it's like, they can get new skin if they need it or have their cancer cells inactivated all through the same research.

Facebook Users More Prone to Developing Eating Disorders, Study Finds
The University of Haifa found a new study, which shows that the more time young girls spend on Facebook, the more chances they have of having eating disorders. These eating disorders could be ones such as anorexia, bulimia, and exaggerated dieting. This study was done with a group of 248 girls ages 12-19. The girls were asked how much they watched t.v and how much they spend online. They were also asked the number of popular shows related to physical images, such as the perfect Barbie image. Also, they filled out a survey of their outlook on slimming down, eating, satisfaction, and personal things. Results showed that the more time that younger girls spend on Facebook, the more they suffered eating disorders such as bulimia, anorexia, physical dissatisfaction, negative self-image, etc.
I believe that this article is wrong. I do agree with it in some ways, but in other ways I disagree because it doesn't make complete sense. People who sit around are more, are prone to eat more, not less. Also, people who sit around are more likely to gain weight because they are not getting any exercise. I do agree with this article some because people do look online (girls more then boys) and see body figures that they would like to have. With this happening, girls can start having eating disorders. But, this article just doesn't make complete sense to me. I think people should get off Facebook and live their lives right!
An Alzheimer's vaccine in a nasal spray
Summary: Researchers are working on a vaccine that promises to protect against both Alzheimer's and stroke. The vaccine repairs vascular damage in the brain by gathering "troops" from the body's immune system. Dr. Frenkel says, "using part of a drug that was previously tested as an influenza drug, we've managed to successfully induce an immune response against amyloid proteins in the blood vessels. Dr. Frenkel believes that this approach, when applied to humans test, will be able to prevent the downward health spiral of Alzheimer's and dementia. So far there have been no signs of toxicity in animals, and Dr. Frenkel is hopeful that this new approach could lead to a cure.
Opinion: The reseach Dr. Frenkel is doing is a very good thing. Many people i know have been effected by this disease and have had to deal with the pain of their loved one not remembering them. If there was even talk of a cure then i'd be all for it. Since there haven't been any toxic effects on animals then we should proceed and try the cure on humans. I enjoyed this current event alot because i could relate to the topic.

Honey Pot Protocells
The article this current even is based on can be found here.
Artificial cells received a near 100 percent success rate at deactivating experimental versions of Nipah and Hendra viruses. These henipaviruses can cause fatal encephalitis, inflammation of the brain, in humans. Henipaviruses, like parainfluenza, mumps and measles, are a part of a called 'enveloped viruses'. Enveloped viruses are surrounded by a two layer lipid membrane, much like that found in the enclosing of animal cells. A pair of proteins embedded in this membrane act to infect host cells. The proteins work together to pull the virus into the cell, and infect it; however, this can only be done once. The protocells are loaded with a protein called Ephrin-B2, this is the target of henipaviruses. They use these cells like decoys, and even cleared out a test solution of active viruses during a controlled experiment. In the long run, scientists say that these protocells could eventually become a sort of antiviral drug.
I find it very intriguing that there could possibly be a new line of antiviral drugs. The success rate of these protocells is astounding, and is no doubt another step in biological research and the medical field. I hope that more protocells such as these can be created and used to work with other forms of viruses. I'm hoping from this there will come more development and new discoveries in the world of science.

Star Shaped Cells
Astrocytes
There are star shaped cell in our brain called astrocytes .They do more than just fill up gaps between between all important neurons . Recent research has proved these cells to do more than they said they did . They play a role in information processing and signal transmission and they help to regulate the shapes of our neurons and the way they connect to eachother. These cell also play a role in long-term memory .I think astrocytes are very important. They help our bodies perform which is a good thing. Without these starshaped cells our brains couldnt function properly. I hope research continues to investigate deeper into their purposes. These cells may help alzhiemers which could be a big realief for families in the U.S
Scientists Discover how Spider Silk Works
http://www.biologynews.net/archives/2011/03/01/scientists_unravel_the_mysterious_mechanics_of_spider_silk.html
Summary
A study by Cell Press looked into exactly what spider silk thread is. Spider silk is known to have strength like steel, toughness like kevlar, and density much less that our materials in use already. Being such an amazing material, in was inevitable that people would want to know how to reproduce it. The study looked into the exact atomic makeup of the two building blocks of spider silk, soft amorphous, and hard crystalline materials. The researchers were able to recreate the thread, using several different patterns to find the one most useful and similar to actual spider silk.
Opinion
This was a good article that outlined a good idea. If humans are able to take something out of nature and recreate it, and have it be better that something artificial, that will benefit us to no end. Not only would it work better that synthetic material, but it would be more environmentally friendly, and possibly more cost effective. The scientists that completed this study had to make the silk from the ground up, starting with the atomic components and building from that. If a process could be developed in which spider silk, or any similar substance, could be mass produced in a lab setting, it could change the way things are made for the better

Liver, Not Brain, May Be Origin of Alzheimer’s Plaques
On March 3, 2011, Scripps Research Institute reported that the original idea of Alzheimer's disease may be altered because of unexpected results from research conducted recently. The liver is now thought to be the source of a substance entitled "amyloid" that contribute to brain plaques associated with the disease. Scientists used a mouse model to test current theories. Their results conveyed levels of presenilin within the liver. That cell membrane protein is thought to contribute to the development of Alzheimer's. Scientists hope that this discovery will lead towards treatments and prevention.
This discovery caught my attention since my grandma has been diagnosed with Alzheimer's. Even though she is in the advanced stage, I hope this research will lead to success in finding a cure for future victims. It seems interesting that the liver would be involved; I've always thought of the origins of Alzheimer's occurring primarily in the brain. This could be a major steppingstone in the progression to end the Alzheimer's epidemic. With the disease expected to spread even more in the future, it's important to commit to research now. This discovery could definitely be a clue in the mystery of Alzheimer's.

mad scientists part 1
So for my next series of scientific icons I chose to do the maddest scientists of all time.To kick things off...Frankenstein. Well, not exactly. Dr.Seregei Bryukhonenko was a Soviet scientist during the time of WWI. His mission or brilliant "stroke of genius" was to find a way to make humans immortal but to start his experimentation he used severed dog heads. His experiment involved the use of his famous invention the autojektor; a heart and lung machine that enabled the decapitated heads to still eat, drink, and most importantly stay alive.
One day he decided to change the animal of chose in his experiment; this time he was going to use snakes. This plan worked surprisingly but not before the snake violently attacked Dr.Bryukhonenko killing him in a matter of minutes. His experiment succeeded in his death. He chose to play with fire by looking for immortality too bad he didn't live to see it through.Talk about irony.
Partners of Cancer Patients Become ill.
Swedish study shows that the person is more vulnerable to illness after marrying a person with cancer. This was found out by cancer nurse Katarina Sjovall from Lund University. She has worked with people with all kinds of cancer. After researching the partners of those cancer patients, 25% more people were diagnosed with cancer. This discovery seems to worry a lot people. It was not only cancer, but other illness such as metal and depression.
This is actually very shocking. To be ill because your partner has cancer. I hope this is not true or it is very rare. To have cancer just because you are with your partner seems like a sad story. Its not only cancer, but a whole bunch of other illness like cardiovascular disease. I hope people will think about this, but not too much and leave your partners who have cancer.

Lactate More Important Then You Think
http://www.biologynews.net/archives/2011/03/03/starshaped_brain_cells_feed_longterm_memory.html
Researchers are finding that the empzyme Lactate may be more important in the brain then we thought. According to their research Lactate is needed to form and remember long term memories but not short term. When they took Lactate away from lab mice and did a series of memory test they remembered for a little while but then later forgot. If the Lactate processes is disrupted then memory problems seem to occur.
I think that this is a very important find, its helping to understand certain diseases like Alzheimer's and Parkinson's. While in the past we thought that Lactate was just needed for energy purposes; we now know that it serves a way more important part. This discovery could be vital to those who are lactose intolerant, where their patterns maybe interrupted often. I really hope they continue their research further.

epilepsy
http://www.biologynews.net/archives/2011/03/01/answers_to_a_rare_and_tragic_form_of_epilepsy.html
In teens there is a disease appearing called Lafora disease. It is genetic and caused by improper glycogen buildup. The enzyme glycogen synthase usually gets on glucose molecules, but about 1 out of 10000 glucose molecules it attaches to a phosphate molecule. They release lafora bodies which are bodies of acid mucopolysaccharides into the brain and neurons. Because glycogen constantly breaks and builds up it gives the phosphate time to build up and cause chemical defects in the glycogen. Scientists are blaming glycogen synthase for the disease.
For those who don't know, epilepsy is a nervous system condition that stops signals to the brain. Glycogen is what stores energy in the liver and present in muscles. Lafora disease is quite painfull if you think about it. It degrates your energy while "poisoning" your nervous system. The comparison to mice shows that that it is most common in us. the second gene leading to the disease sounds like a possible link to finding a solution

Eastern Cougar is Declared Extinct, With an Asterisk
http://www.nytimes.com/2011/03/03/science/earth/03cougar.html?_r=1&ref=science
Kendall Roberson
This past Wednesday, March 2, 2011, the Eastern Cougar was declared extinct. The last Eastern Cougar seen was seven decades ago and the Fish and Wildlife Service were the ones who declared it extinct, and it should be taken off the nation's endangered species list. However, many scientists believe that the Eastern Cougar is not actually extinct. A genetic study that took place in 2000 established that there is no real difference between the eastern and western cougars. The last known Eastern Cougar was trapped in the late 1930's and was held captive, according to the Fish and Wildlife Service.
I believe that the Eastern Cougar is extinct. Even though some scientists believe it is not because of the relatively close genetics of the Western Cougar, the "Eastern" Cougar is technically extinct. The Fish and Wildlife Service is an educated organization and they know more about the ecosystem and wildlife than anyone else in the country. If scientists were so worried about the Eastern Cougar becoming extinct, then they should have tried to reproduce it in the late 1930's with the last of the Eastern Cougar species. Now, since the Eastern Cougar is extinct, it cannot be reproduced or brought back into the ecosystem, which can hurt more than just the cougar population. The Eastern Cougar should be taken off the endangered species list because it is now extinct.

Savanna Elephants
Agustin Gonzalez
Article Summary:
Since the year 2006, over 2,000 Elephants have been found dead in an African Park near the Sahara Desert. So after a long time of investigating, they have finally realized the problem.
The problem was that many Ivory poachers have been killing off many of these parks many elephants, and have been at it for a while. Because of them, the elephant population has rapidly decreased and is causing a problem for them. Also, while trying to stop these poachers, many park gaurds and rangers have been shot and killed or severly injured.
Opinion:
I'm wondering if the poachers will ever get caught and if anymore casualties will happen as a result of the poachers not being caught. I aslo wonder if they will become an extinct group of elephant if they keep dying off. If the elephants are dying off will it affect the benefits of the entire park. and if the poachers are ever caught, what was their purpose for killing off the creatures in the first place. I heard that there are up to 3,500 elephant now dead.
Blood protein in lung cancer could improve diagnosis and treatments.
Scientists have reported the discovery of a protein in the blood of a lung cancer patient that could be used in tests for the disease and to develop drugs that prevent lung cancer from spreading. The scientist understood how difficult it was to diagnose a patient of lung cancer when it was in the early stages. So to find a better diagnostic tool the researchers studied the proteins in the blood of lung cancer patients in search of some kind of signal to show the diseases presence. The scientist studied the most rapidly increasing form on lung cancer in women called adenocarcinoma and found elevated levels of a certain protein that would only exist in adenocarcinoma patients. This showed the high amounts of SSA that are unique to all lung cancers, signally the difference between the patient with the disease and a healthy patient without it.
I think that these tests are a great advance for lung cancer patients. The researches have found an extraordinary discovery of the protein in the patients blood, the protein could be used as a diagnostic marker for lung cancer as a target for developing drugs that stop the spread. Lung cancer is difficult to diagnose in the earliest stages and because of this study Doctors may have the ability to diagnose lung cancer in a much earlier stage. Scientist have noted that lung cancer is the leading cause of cancer related deaths worldwide. A huge reason to why the cancer is so deadly is because of its tendency to spread to different parts of the body, such as the brain or the liver. In result, these tests are very beneficial for the life of the lung cancer patient and the study of the scientist.

Alzheimer's Vaccine?
http://www.biologynews.net/archives/2011/02/28/an_alzheimers_vaccine_in_a_nasal_spray.html
An influenza vaccine turned into an Alzheimer's vaccine can now prevent strokes and Alzheimer's disease in one tiny spray. This can stop current Alzheimer symptoms and prevent future symptoms from occurring. It guarantees to protect from stroke, a cause of Alzheimer's. It can also reverse brain tissue damage. It tricks the brain into producing more healthy cells that can be used to attack the Alzheimer's and prevent the strokes from happening. Currently, no animals have shown any poisonings from this, and it is said to cure 80% of trial patients.
I find this astonishing that scientists/doctors basically found a cure for Alzheimer's. This is completely mind boggling. Although, I would be skeptical to try this. It sounds like a good idea in theory, but it has been tested only on animals, and a few select patients, it has yet to go "mainstream". I feel it would make me more susceptible to a stroke than to prevent it. Maybe within a few more years of testing, they can completely put Alzheimer's to a halt, and make the vaccine mandatory, like Polio or Hepatitis.

Algae Converted to Butanol; Fuel Can Be Used in Automobiles
Algae is a very abundant source on this planet mostly due to the fact that algae can grow anywhere you can find water and sunlight. Scientists at the University of Arkansas have been able to convert algae into Butanol, a substance that can replace fuel currently used in automobiles, petroleum, diesel,and even methanol. It is due to the fact that algae uses nitrogen and carbon dioxide in water to grow, so scientist put concentrated amounts of carbon dioxide into tanks and the algae naturally converts it to oxygen. scientists use the carbohydrates also produce and they turn them into simple sugars. They then begin a process in which organisms turn the sugar in to acids that can be used to make Butanol.
Opinion
Scientist have now found a new way to make fuel that is made safely through photosynthesis. this new fuel source that is safe and easy to make be it is also very abundant and renewable! Algae can now practically anywhere so scientists won't have to use food to make their fuel, as with methanol. It is also a way to reduces carbon dioxide in the atmosphere because the algae lives off carbon dioxide, and scientists speed up algae growth with waste and the algae, through photosynthesis, converts it into to oxygen. This will not only save money, but it will also help the environment.
Bacteria Communicate with Nanotubes
Bacteria are known to communicate with each other by means of excreting and recieving extracellular signaling devices. These devices allow bacteria to execute tasks such as antibiotic production and producing virulence factors. Professor Sigal Ben-Yehuda and her team of scientists at the Hebrew University of Jerusalem have discovered a new form of communication, involving nanotubes that connect both similar and different bacteria. These nanotubes allow bacteria to exchange small proteins, molecules, and even some genetic elements. These nanotubes may allow multiple types of bacteria to acquire antibiotic resistance, and therefore open up a new way to fight pathogenic bacteria.
I think that this discovery by Professor Ben-Yehuda will lead to the development of new types of antibiotics, and help the fight against bacteria. Scientists are already working as fast as they can to outrun bacteria in the race of antibiotics versus resistance, and this discovery may be able to slow down bacteria's rate of resistance. While it might not cure us of harmful bacteria, this discovery will allow us to fight them better.

spider silk
link: www.biologynews.net/archives/2011/03/01/scientists_unravel_the_mysterious_mechanics_of_spider_silk.html
Summary: Scientists begin to "unravel" the mystery as to why spider silk is so strong. The two main things in spider silk are soft amorphous and strong crystalline. Scientists began by studying the atoms that make up amorphous and crystalline. After dissecting the materials, scientists discovered the soft amorphous is responsible for elasticity, and the crystalline is responsible for "toughness".
Opinion: This is really cool. Eventually I am hoping that they will make other things based on the ingredients of spider silk. It is extremely cool that that silk can hold the spider up, and catch dinner all at the same time, I wonder what it could do for humans.

Alzheimers disease will claim eight out of ten American lives. A new way to cure it is being tested and it will be a nasally taken 2-in-1 vaccine. This treatment is said to protect you from Alzheimers and stroke. It can also still work when Alzheimers symptoms are already in place. It's also proven in pre-clinical studies that it will prevent brain tissue damage and restore cognitive impairment.
This will be useful because Alzheimers claims so many lives. Will all this coming in who knows what we'll invent next. But with all these guarantees will they end up truthful. People also do not die of Alzheimers they die of a stroke they get when they have Alzheimers. This concludes my event. Thanks for reading! :)

Rare 89-Million-Year-Old Flying Reptile Fossil from Texas May Be World's Oldest Pteranodon
Just north of Dallas, a fossil of a flying reptile was found. Called the Pteranodon, it may be the oldest specimen of its kind yet. It is said to have lived over 89 million years ago. This is the first time this animal has been found in Texas so far. A large bone of the left wing was discovered which made it easier to identify the reptile.
Another dinosaur has been found in America. Many dinosaur fossils are being found which shows that there must have been many dinosaurs in this area. It seems like being a paleontologist would be interesting since so many fossils are being found. The more fossils that are found, the broader our knowledge can get about dinosaurs. From fossils like these, new discoveries can be made about their habitat, diet, predators, etc.
