Researchers at Princeton University have conducted research into the security of electronic voting machines. They have created a virus that could breach voting machines and change votes. The creators of the voting machine say the research was unrealistic.

Edward William Felten, a professor of computer sciences and public affairs at Princeton University, and two Princeton graduate students, Ariel Feldman and Alex Halderman, created a computer virus that they say could remain concealed in tests, “steal” votes, delete itself to go undetected and spread to other machines.

They used a Diebold AccuVote-TS which is a small computer with a touch screen. The latest version of the software used 128-bit data encryption, digitally signed memory card data, secure socket layer (SSL) data encryption for transmitting results and dynamic passwords.

They opened the drawer with a key, picked the lock or undid screws to open the compartment that allows them to change the memory card. They suppressed the beep created by the computer when it reboots by using headphones. They say the virus can spread by using the same memory card which when inserted into a different machine will infect the machine.

The researchers say they received the machine they tested on from someone who wants to keep their name anonymous.

“You have to be a good programmer — not a genius — to do this,” Halderman said. “I believe a good programmer could reproduce our virus without very much effort.”

“Analysis of the machine…shows that it is vulnerable to extremely serious attacks,” the report states. “An attacker who gets physical access to a machine or its removable memory card for as little as a minute could install malicious code.”

Diebold Election Systems president Dave Byrd said that the research was done with security software that were two generations old.

“By any standard–academic or common sense–the study is unrealistic and inaccurate,” he said in a statement.

“Normal security procedures were ignored. Numbered security tape, 18 enclosure screws and numbered security tags were destroyed or missing so that the researchers could get inside the unit. A virus was introduced to a machine that is never attached to a network.”

“Every voter in every local jurisdiction that uses the AccuVote-TS should feel secure knowing that their vote will count on Election Day,”

“That’s what they were saying a few years ago,” said Halderman. He said he would very much like to study Diebold’s newer machines and software. “We expect and fear, unfortunately, that if we were to examine the newer version of the software, we could find similar problems.”

NASA has stated that the Mars Phoenix lander is having trouble analyzing soil samples that its robotic arm is collecting. According to NASA, the soil appears to be too clodded to pass through screens on the way to Phoenix’s Thermal and Evolved-Gas Analyzer (TEGA).

Images taken by the lander’s camera shows that the robotic arm has dumped a large portion of soil over the TEGA, but it failed to register any soil which might have passed through the screens leading into the analyzer. The screen is designed to let through particles up to one-millimeter (0.04 inch) across while keeping out larger particles, in order to prevent clogging a funnel pathway to a tiny oven inside. An infrared beam crossing the pathway checks whether particles are entering the instrument and breaking the beam. It is now believed that the particles are either too large to pass through the screen, or the soil is too clumpy.

“I think it’s the cloddiness of the soil and not having enough fine granular material. In the future, we may prepare the soil by pushing down on the surface with the arm before scooping up the material to break it up, then sprinkle a smaller amount over the door,” said Ray Arvidson of Washington University located in St. Louis, Missouri. Arvidson is the Phoenix team’s science lead researcher for Saturday and digging czar for Phoenix’s mission.

NASA also plans to use a shaker inside the TEGA to shake any material or samples longer than previously planned in an attempt to break up the larger particles and clumps. Phoenix already utilized this method on Friday June 6, shaking the soil for five minutes before dumping it onto the screen. NASA plans to tell Phoenix to shake the material a little longer in order for the soil to be tested.

While scientists ponder ways to fix the issue, TEGA will not be analyzing any samples. Instead Phoenix is expected to have completed tasks today such as horizontally extending a trench where the lander dug two practice scoops earlier this week, and taking additional images of a small pile of soil that was scooped up and dropped onto the surface during the second of those practice digs.

The Boston College men’s basketball team defeated the North Carolina State Wolfpack at home in a 74-72 double-overtime thriller on Feb. 25. The BC Eagles, ranked #11 going in to the contest, left with a 22-6, 9-5 record in the Atlantic Coast Conference, while the NC State Wolfpack dropped to #19 after the game with a 21-7, 10-5 record.

Boston College star Sean Marshall finished with 22 points, including three 3-point shots, while Craig Smith had 18 points, 14 rebounds and six assists for the Eagles.

Ilian Evtimov led the Wolfpack with 16 points.

BC outscored the Wolfpack by two in the first half, which was reversed in the second half. Only Miller’s second overtime 4-pointer put BC decisively in the lead and allowed them a victory.

By causing the mutation of one specific gene, researchers have produced mice with two frequently encountered behavioral traits of persons diagnosed with autism. Autism commonly affects the ability to interact socially and is associated with repetitive behavior. The finding was reported in the March 20 online edition of Nature.

Using mice, researchers at the Massachusetts Institute of Technology (MIT) and Duke University mutated one of the genes associated with autism, known as shank3, a gene that controls the production of the shank3 protein present in the brain. Mice that were given this mutation exhibited repetitive behavior and avoided social interactions with the mice around them.

According to MIT Professor Guoping Feng: “Our study demonstrated that Shank3 mutation in mice lead to defects in neuron-neuron communications.”

Shank3 protein are found in synapses within the brain. Synapses allow brain cells (called neurons) to communicate with each other. The mutation in the mouse gene interfered with this communication, apparently producing the subsequent autism-like traits. Researchers believe their work demonstrates the important role of shank3 in the functioning of brain circuits that determine behavior.

While hundreds of genes have been linked to autism in human patients, only a small percentage have been linked to shank3. Professor Feng hypothesizes that disruptions of other genes that act on the production of brain proteins affecting synaptic communication may also be related to autistic behavior. If this disruption is real, Feng claims that treatments could be developed to correct synaptic function for any defective synaptic protein in an autistic patient.

Feng continued; “These findings and the mouse model now allow us to figure out the precise neural circuit defects responsible for these abnormal behaviours, which could lead to novel strategies and targets for developing treatment.”

About one in 110 children in the U.S., and at least one in 100 in UK, have been diagnosed with an autism spectrum disorder, for which there is currently no effective cure.

Turkey’s Finance Ministry has given Google a tax demand of $18.6 million, and Transport and Communications Minister Binali Y?ld?r?m called on Google to register as a taxpayer in the country to “help accelerate” the lifting of a ban on YouTube and Google services.

As The Register reported, access to search engine Google had been limited due to a block imposed on its IP set, and most of Google’s online services had been inaccessible in Turkey since June 4. The IP addresses were shared between YouTube and other Google services. As International Business Times reports, YouTube has been banned in Turkey since 2008.

Accoring to HaberTurk, which is the Turkish version of Bloomberg, Yildirim said that “YouTube is a tax-payer in 20 countries, and we want them to do the same in Turkey.” Turkey’s Finance Ministry has given Google a tax demand of $18.6 million. Y?ld?r?m called on Google to register as a taxpayer in the country, and he said that it is a step that “would help accelerate the lifting of a ban on the company’s Youtube video-sharing website.”

Reporters Without Borders condemned “the growing repercussions of Turkey’s censorship of YouTube” and quoted Turkey’s President Abdullah Gul as saying “I do not want Turkey to be included among the countries that ban YouTube and prevent access to Google.”

Several internet sites have recently been banned in Turkey. The Register reports that 3,700 websites are “blocked for arbitrary and political reasons” in Turkey, including foreign websites, sites aimed at the country’s Kurdish minority, and gay sites according to The Organisation for Security and Cooperation in Europe (OSCE). Reporters Without Borders added Turkey to the list of “countries under surveillance” in its report on “Enemies of the Internet,” issued March 2010.

According to media reports, a Colombian air force AC-47 (registration FAC1670) spy plane carrying five people has crashed near the Colombian city of La Dorada, in the department of Caldas.

All on board the plane are believed to have been killed, according to Colombia Reports. Among the dead, according to Monsters and Critics, are two technicians, a major and two second lieutenants. ABS-CBN News reports that the dead included three high ranking officials and two lower ranking ones.

Jorge Ballesteros, a Colombian air force official, says that the plane took off from an air force base in the city of Puerto Salgar and was on an exercise mission when it crashed. He also states that although it was on a training exercise, the plane was carrying bombs and machine guns.

A military team has been dispatched to the area to investigate the incident, but they have already put the blame on mechanical failure. Ballestero noted that investigators have ruled out a rebel attack and terrorism as possible causes.

AC-47’s have been used by the Colombian air force for nearly 20 years, most of which were donated from the United States. They were provided to the country in an attempt to fight the illegal drug market and to defend citizens and the military against rebel attacks. They are also used to gather intelligence and come equipped with a state-of-the-art communications system, radar and infrared detection systems.

Wikinews held an exclusive interview with Wayne Allyn Root, one of the candidates for the Libertarian Party nomination for the 2008 U.S. presidential election.

Root is the founder and chairman of Winning Edge International Inc., a sports handicapping company based in Las Vegas, Nevada. In addition, he is an author and a television producer, as well as an on-screen personality both as host and guest on several talk shows.

Root, a long-time Republican, declared his candidacy for the Libertarian Party on May 4, 2007.

He says he is concerned about the qualities of many who run for president, and fears that they do not know the needs of American citizens. He also says that they cater to big businesses instead of small ones.

He has goals of limiting the federal government and believes that the US went into Iraq for wrong reasons. A strong supporter of the War on Terror, he feels that it was mishandled. He has conservative values and came from a blue collar family in New York. He graduated from Columbia University with fellow presidential hopeful Barack Obama in 1983.

Root believes that America is in trouble and hopes to change that if elected.
