The Arsenic Monsters!!!
Date: December 2, 2010
Length: 5 pages
Title of Article: A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus
Summary By: Anastasia
Article Summary:
All living things are mostly composed of 6 major elements: carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorous. No organisms have been found that don't follow this rule - until now, that is. NASA scientists have recently discovered a bacterium that can replace the phosphorous in its cell body with arsenic, an element that, while similar to phosphorous in structure, is nevertheless toxic to most living things. The environment where these little arsenic monsters live (Mono Lake, CA) has little phosphorous, but a very high concentration of arsenic. The bacteria have taken advantage of this by evolving the ability to incorporate arsenic into those structures in their cells that would normally require phosphorous. This by itself is not surprising; around 20 other types of bacteria can do this. What makes these bacteria from the Halomonadaceae family special is the fact that they can live entirely on arsenic, without using phosphorous at all. It is the only known organism that can do this.
Scientists discovered this organism's special secret by isolating it from the mud on the lake's bottom and growing it in a petri dish. Gradually, they gave the bacterial less and less phosphorous and more and more arsenic, until, eventually, there was no phosphorous in the dish at all. They were surprised to find that the bacteria were still able to thrive in these circumstances.
Conclusion:
This discovery is important not only in a biological sense, but also in the context of space science. Many planets have different ratios of elements than we do here on earth. Previously, those planets that did not contain large amounts of the 6 elements vital for Earth life were dismissed as unsuitable for any life forms. However, these arsenic-munching bacteria prove that it is possible for organisms to do without at least one of these 6 elements, raising new possibilities and hopes in the search for extraterrestrial life.

Main Idea
The Supporters of prop 8 are trying to repeal the walker decision that said that prop 8 is
unconstitutional. This Morning Monday December 6 the lawyers that want prop 8 to be upheld
and don’t want same sex marriages are fighting in court. The court has gone back and forth on
this issue since 2008.
• May 15 2008 the judges ruled that same sex couples have the right to marry.
• Proposition 8 was passed in the November 2 Elections. Said that only men and women can
get married.
• August 4,2010 Judge Vaughn Walker said prop 8 is unconstitutional
Conclusion
Currently same sex marriage is illegal but later in maybe years from now to say what is
constitutional and what’s not. The case will eventually end up in the California supreme court

Privacy vs. Commerce: Lawmakers Debate Wisdom of 'Do Not Track' Laws
Something very disturbing to all internet users are they're still being secretly tracked by companies from all over. Research shows they are more invasive than we thought. For example, when telemarketers got out of hand, the government responded with the 'Do Not Call' list, and now, Lawmakers debate the 'Do Not Track' list. There were very powerful responses from both lawmakers and witnesses on regulating online tracking. Susan Grant, the director of consumer protections at the Consumer Federation of America said, “companies already track consumers' every online move, often without their consent. If someone were following you around...tailing you and making note of everywhere you go, what you read, who you talk to, what you eat, the music that you listen to, what you buy, what you watch, you might find this disturbing.” Daniel Castro, a senior analyst with the Information Technology and Innovation Foundation, said, “'Do not Track,' of course, doesn't actually stop online advertising, it only limits the ability of ad networks to deliver ads the user might actually want. Users who opt out of tracking would receive more – not less – unwanted advertising.”
Conclusion
The 'Do Not Track' list is actually extremely different from the 'Do Not Call' list. It's not like the companies like Sears can listen to all your phone calls and just interrupt with a Sears ad. The 'Do Not Call' list is a lot simpler and straightforward. The 'Do Not Track' list is more complex, there are good and bad sides to it because either way, there will always be ads on whichever site you visit, the only difference is if the ad actually fits the consumers need. I think the 'Do Not Track' list should not pass because you will always have ads, the only difference is it only limits the ability of ad makers to deliver ads the user might actually watch rather than having a completely irrelevant ad.

Title: Drugs common in fatal car crashes
Writer: David Martin
Publication Name: CNN, the chart
Date of Publication: Nov 30, 2010
Length: 439 words
David Martin, the Senior medical producer at CNN, researched the link between car accidents and drug use. This was the first ever drug analysis of drivers performed in 2009, as reported by the Office of National Drug Control Policy.
These studies have shown that 1/3 of every person killed in an accident in America, had been under the influence of drugs. This article sheds light on the fact that driving under the influence of drugs can be just as, if not more dangerous than driving under the influence of alcohol. This study has shown that illegal drugs are not the only type of drugs that can impair you enough to cause an accident that could have been prevented. Prescription drugs have also been known to cause impairment in drivers, causing accidents.
Although drug companies deny taking any responsibility for the accidents caused by consumer drug consumption, this study has linked the cause-effect relationship between over-the-counter and prescription drugs to car accidents.
Gil Kerlikowse, director of the national drug control policy said that the percentage should serve as a wakeup call for people who drive under the influence of drugs. For example the 10.5 million people age 12 or older reported driving under the influence illicit drugs during the past year. Or the about 4 percent of the population. Hopefully people will wake up and stop driving under the influence of drugs.

Title: Amazon Bows To US Censorship Pressure: Refuses To Host Wikileaks
Publication Name: Amazon takes action against Wikileaks. Writer: Mike Masnick
Date of Publiction: 12/1/10 Words: 1000
- Main Ideas: Amazon has officially denied hosting the WikiLeaks website. The site, “WikiLeaks” has been a hot topic in the media because the site has allegedly been releasing “secret information” which could affect “national security”. In reality the site is realizing articles that are well within public domain. WikiLeaks shares articles, which discuss government and military mishaps, which is not illegal. Many officials however, feel that this is a threat to national security, and are looking for a way to extend the espionage act, to ban WikiLeaks off of the web. In the meantime, more traditional ways of censorship are being used to block the site. Senator Bill Lieberman is the main voice in the expansion of the espionage act in order to ban WikiLeaks. Senator Lieberman was quoted saying “…this site is a definite threat to both the white house, and the military. They are releasing misguiding and often false information about the U.S. government, which should be deemed unconstitutional. As of now the WikiLeaks site is public domain and is protected by the 1st Amendment, but officials say that until a ban can pass through congress and the senate, the only way to combat this site is to put pressure on those sites which support it. Amazon dumped WikiLeaks after much pressure from the government, and it seems many other search engines are soon to follow.
- Conclusion: WikiLeaks is not violating any laws. Although they do provide articles, which are often misleading and may not portray the U.S. government and military in good light, they still have a right to express their opinion under freedom of speech. However, the espionage act, if amended to deal with WikiLeaks, does have a right to censor what the country deems as a threat to national security. The government sees WikiLeaks as a fountain of doubt and mistrust, which would affect the minds of many American citizens. In these hard times, officials don’t want Americans to lost any more trust in the government, and therefore banning WikiLeaks seems essential.

Title: state board of education makes change to starting age for kindergarten
Writer: Eileen FitzGerald

Length: 341 words
The State Board of Education in Connecticut and three other states have changed there starting age from five years old in January to 5 years old in October. This change will take a total of four years to complete because they want to do it gradually. By next year the dead line to be five will not by January but it will be December first, by 2013 the day will become November first, and in 2014 it will make it to its final spot of October first. There are a few reasons for this change one of them being that some kids need to experience more pre-school activities to develop. Another reason to change the age for kindergarten is that it will lesson the gap between age within the classroom, which will allow the kids to develop better and faster. Also this will become a more efficient kindergarten system after the transformation is finished. For all these positives there are also some negatives for example some of the underprivileged children and there familys will have to, in some cases pay for anther year of child care. This will not effect some familys because the State Board of Education in these four states will provide 27.5 million dollars for the year of care. The new age of this change will effect about 7,500 kids who are in the age group that are going to have to another year of pre-school.
Conclusion: These changes to me seem to be pointless and that it is a waist of mony for the schools and the parents of the kids who are affected. Although this change is supposed to help develop kids faster and better I believe that it is not worth 27.5 million dollars for something that might work. This bill will help the development of the kids but with a dent in the schools wallets.

Main Idea:
On Wednesday, President Obama reversed a decision to expand off shore oil drilling to the Atlantic ocean and eastern gulf of Mexico. However he still allowed deep sea drilling in the gulf where the oil spill happened. the move banned oil drilling in new areas until 2017. there were mixed reaction among the states hit by the oil spill. Florida said the decision would safeguard the areas tourism and fishing industry. Louisiana, on the other hand disagreed saying it is a major step backwards for energy security. Texas Congressman John Culberson gave it the thumbs down saying that it would harm the economy by raising energy prices. Also the Natural Resources defence council says that the move did not go far enough because it left the door open for drilling in the arctic and allowed seismic testing in the Atlantic, both of which are harmful to the environment.
Conclusion:
President Obama reversed a decision to expand offshore oil drilling in new areas until 2017. states hit by the oil had mixed feelings about the decision. some say it was a good decision, while others say that it could harm the economy. One group said it did not go far enough because it left too many doors open for drilling elsewhere.
Caffeine and Alcohol Drink is Potent Mix for Young

Title: Caffeine and Alcohol Drink is Potent Mix for Young
Writer: Abby GoodNough
Publication Name: NY Times
Date of Publication: October 26 2010
Length: 1069 words
Summary:
New beverages called Four Loko that mix alcohol and caffeine into an intense fruity flavor, have blown up in popularity among teenagers. These drinks are not only illegal for people under the age of 21, but they are also very dangerous for the human body. Normally when someone takes in alcohol, their body, at some point will stop communicating with the brain and they will either pass out, or regurgitate the substance. But with the caffeine now added to the mix, it tricks the body by keeping the body in a "normal state" so the person will keep on consuming alcohol till they become seriously ill. In a small school called Ramapo College in New Jersey, a number of students had been hospitalized due to the affects of the four loko drink. The president of the college has banned the drink and is encouraging others to do the same. The Food and Drug Administration is investigating whether the mixing of alcohol and caffeine is safe for the human body. This drink is very cheap, so it is very affordable for college students and teenagers. Yes, the law does state the you must be under the age of 21 to consume alcohol, but many kids and young adults ignore this law. Thus being said, people are questioning the owner of four loko and are asking him if they are trying to target a younger group. Even the cans look like the energy drinks/ice tea drinks that kids drink, parents said that they didnt even notice that the drink that their child was drinking was illegal.The owner, Michael Michail says that the company has no intention to sell to minors and that on the can, it states multiple times that the drink has alcohol in it.

Some children who have epilepsy are having up to 130 seizures a day and are unresponsive to medication. So there is a new diet called the Ketogenic Diet.
Conclusion: This diet seems like an alternative to harsher drugs, and also could potentially be cheaper. Instead of putting money into buying strong medicine the money could be put into buying food instead. More hospitals should be prescribing this diet to parents who have tried everything. Although parents will eventually have to look for another alternative, this will work for the time being. This diet seems to be an improvement in the epilepsy treatments.

Title-Mystery Surrounds Cyber Missile That Crippled Iran's Nuclear Weapons Ambitions

Through a computer virus that manipulates windows software using zero days which are unidentified wholes in a systems security in this case windows 7 which are used to run Iranian nuclear facilities. Tncredibly complex the worm had multiple stages and was manipulating the system into thinking that it didn't exist. It was capable of penetrating a non server based operating terminal that had no connection to the world wide web. The worm was programmed almost exclusively for the sabotage of the Iranian nuclear facilities and was able to get onto the computer terminals and manipulate the logic controllers of the facility through workers using flash drives to connect to the terminals. The worm targeted workers around the facilities infecting all the computers and because it is able to use the operating system to hide it it wasn't found. The ingenuity of the worm is that is specifically targeted usb sticks to get onto the control computers because of the previously stated reasons. The planning and thought put into to the writing of this worm must have been years in the making a monster of a worm that can be used for industrial espionage and will undoubtedly be used in such terms because of its unique capabilities(the ability to control programmable logic controllers which are used to control robots). the program can erase its traces in the computer trace log which is how it hides its tracks. Perhaps the most incredible thing is that the worm is constantly being updated in fact they think that some anti virus programs are actually programmed to update the virus instead of get rid of it. The virus was discovered on august 6th this year and the writer is unknown but is thought to be a combination of us and Israel intelligence agency and is estimated to have taken 10000 man hours to write. The day that they found the worm the people who made it were able to erase it withing 24 hours of it being found.
Update on WikiLeak Cables
From info on the diplomatic cables Afghanistan appears to be one of the most corrupt countries in the world. Information on bribery, extortion and embezzlement seem to imply that in Afghanistan they are the norm. for politicians. There was also information that several of these ambassadors took money from American development projects. One official from Afghanistan explained the four times when the corrupt officials steal the money. These are when contractors bid on a project, at application for building permits, during construction, and at the ribbon-cutting ceremony. A while ago Abdul Ahad Sahibi a mayor in Afghanistan was aressted for massive embezzlement in as a "small victory against corruption". However, according to the cables this man was framed for this crime because he was trying to halt a corrupt land-distribution scheme. This sadly increases the idea that honest men in that government are few and far in between and sadly the rare kinda of politician you can find. An advocacy organization Transparency International has ranked Afghanistan as the 3rd most corrupt country in the world. This ranks it as only being behind Somalia and Myanmar. In the summer of 2009 a report from Kabul stated that President Hamid Karzai “allowed dangerous individuals to go free or re-enter the battlefield without ever facing an Afghan court.” Mr. Karzai also pardoned a border police officer who was found with approximately 273 pounds of heroin. He also intervened in a narcotics case involving the son of one of his wealthy supporters. This only can increase the fear and blatant obviousness of a drug trade fulled government.
