In the Northern Territory of Australia (NT), voters in the electoral division of Daly are scheduled to vote for a new Member of the Legislative Assembly (MLA) tomorrow. The previous Member, Ian Sloan of the Country Liberal Party (CLP), resigned in August. Daly covers communities near Darwin, as well as more remote places such as Timber Creek and Wadeye.

Via email, Wikinews interviewed Rebecca Jennings, who is standing in the Daly by-election as an independent candidate. Jennings previously contested the 2020 Northern Territory general election as a candidate for the Territory Alliance party. She ran in the Fannie Bay, and received 242 votes (5.6% of the vote).

Consumption of grilled or baked fish at least once a week can preserve the brain structure of seniors and reduce the risk of developing Alzheimer’s disease by three to five times, according to the results of a recent US study.

The study, conducted by the University of Pittsburgh School of Medicine in Pennsylvania, asked 260 volunteers with an average age of 76, about the frequency of their fish consumption. Ten years later, brain scans were carried out on those being researched. Those who regularly ate fish were found to have better preservation of parts of the brain related to memory. An additional five years later, 31% of those who did not regularly consume fish contracted mild cognitive impairment or Alzheimer’s disease. Of those who ate fish at least once a week, between three and eight per cent contracted the aforementioned medical conditions.

According to The Daily Telegraph, consumption of grilled or baked fish increases the intake of Omega 3 fatty acids, providing a greater amount of blood flow to the brain; therefore prompting a reduction in inflammation and internal gathering of plaque encountered in the lead-up to Alzheimer’s disease. Fried fish does not reduce the risk of contracting Alzheimer’s disease due to the low amount of Omega 3 it contains.

Dr. Cyrus Raji, who took leadership of the study, called it “the first study to establish a direct relationship between fish consumption, brain structure and Alzheimer’s risk.” Raji concluded that “people who consumed baked or [grilled] fish at least one time per week had better preservation of grey matter volume on MRI in brain areas at risk for Alzheimer’s disease.”

The Alzheimer’s Society’s research manager, Dr. Anne Corbett, stated: “This moderately sized study adds weight to existing evidence suggesting that eating fish reduces your risk of developing cognitive decline.” However, she contested these findings, saying they “did not account for lifestyle factors such as other foods or exercise”, which may have affected the overall outcome. Dr. Corbett advised consumers to “eat a healthy diet including fruit and vegetables along with taking regular exercise and giving up smoking” to reduce the risk of contracting dementia.

Meanwhile, Alzheimer’s Research UK lead researcher, Dr. Simon Ridley, believed the study had not clarified “whether other underlying factors may have contributed to the lower risk in people who eat fish.” There is “a clear need for more conclusive research into the effects of dietary fish on our cognitive health,” according to Dr. Ridley.

The results of the study are to be presented today at the annual meeting of the Radiological Society of North America.

Aung San Suu Kyi, the detained leader of the National League for Democracy in Myanmar marked her 62nd birthday today, still under house arrest, where she has spent most of the past 17 years.

About 250 supporters met at the National League for Democracy (NLD) headquarters in Yangon, not far from Suu Kyi’s home, and held a rally calling for her release. Doves and balloons were released into the air, under the watchful eyes and video cameras of around 50 plainclothes police officers, who were stationed across the street.

The police force was augmented by a dozen truckloads of members of the Union Solidarity and Development Association, the political arm of the State Peace and Development, the junta that rules Myanmar.

“The doves symbolise peace. We also released colourful balloons, which rise like her prestige when they fill the sky,” NLD women’s wing leader Lai Lai was quoted as saying by Agence France Presse.

With the party marking marking Suu Kyi’s birthday as “Myanmar Women’s Day,” Lei Lei read out a statement at the ceremony, calling Suu Kyi “irreplaceable” and praising her “honesty, bravery and perseverance.”

Security was beefed up around Suu Kyi’s lakeside home on University Avenue, which is usually open to traffic during daytime, but is closed on significant anniversaries such as Suu Kyi’s birthday or the May 30 anniversary of her detention.

NLD supporters said police were also watching their homes.

“Plainclothes police circled around my house on their motorcycles last night until dawn,” Su Su Nway, 34, was quoted as saying by Agence France-Presse. She was arrested on May 15 with 60 others during a prayer rally for Suu Kyi in Yangon, and was released for health reasons on June 7. She said around 52 NLD supporters were still in custody.

Suu Kyi is generally barred from receiving visitors, so she spent the day alone. Except for her maid, a personal physician, a dentist and an eye specialist, the only other person to visit with Suu Kyi in the past year was United Nations Undersecretary-General for Political Affairs Ibrahim Gambari, whom she met for one hour last November at a government guest house.

Winner of the 1991 Nobel Peace Prize, Suu Kyi has been under house arrest for 11 of the past 17 years, continuously since 2003. Her National League for Democracy won a landslide election in 1990, but the military, which has ruled Myanmar since 1962, refused to honor the results. The country is also known as Burma, but the military government renamed it Myanmar in 1989.

Calls for Suu Kyi’s release have been issued by the NLD, various world bodies and other countries, but the pleadings have been met by no response from the generals.

“In our view, until their constitution is ratified, she will not be released,” Sann Aung, a Bangkok-based leader of the Burmese government-in-exile was quoted as saying by Reuters.

“They are worried that she will be a threat to the National Convention and the referendum,” he told Reuters, referring to the planned national referendum on a new constitution that is being written by the generals.

The Nation newspaper in Bangkok marked Suu Kyi’s birthday with an editorial, saying that sanctions against the Myanmar regime have been ineffective.

“The junta has earned huge amounts of foreign revenue from oil and gas exports, with prices jacked up many times over. With rich mineral resources, energy hungry countries have been attracted to Burma despite the repressive nature of the junta,” the editorial said, also making note of a recent deal that Russia has made to build nuclear reactor in Myanmar.

The paper also said Myanmar bodes ill for the 10-member Association of Southeast Asian Nations regional grouping.

“As long as Aung San Suu Kyi remains incarcerated, ASEAN’s reputation and the group’s international standing will be tarnished. Asean leaders have repeatedly appealed to the Burmese junta to free her, but to no avail … today, Burma is the black sheep of ASEAN. Without any current provisions for sanctions, Burma will remain as intransigent in the future as it is today.”

The 20th annual World AIDS Day was December 1, 2007. The theme selected by the World AIDS Campaign is “Stop AIDS: Keep the Promise” as it will be through 2010. The day was marked by thousands of events around the world.

“It is now time for bold leadership at all levels in order to turn the tide of HIV,” said Felicita Hikuam, Global Programmes Manager, World AIDS Campaign. An estimated 33.2 million people around the world—one in every 200—are living with HIV, and approximately 6,800 people are infected with HIV and 5,700 people die of AIDS-related illnesses every day.

“The trend is encouraging but still for every person receiving treatment four others are newly infected,” said Nelson Mandela, speaking at a concert in Johannesburg, South Africa. “If we are to stop the Aids epidemic from expanding, we need to break the cycle of new HIV infections. All of us working together with government, communities and civil society can make the difference that is needed,” he continued.

As many as 50,000 people attended the concert in Johannesburg, South Africa, which was telecast around the world. It was organized by Nelson Mandela’s 46664 AIDS campaign and featured performances by artists such as Peter Gabriel, Ludacris, Razorlight, the Goo Goo Dolls and Annie Lennox.File:20050702-Nelson Mandela Live8 Edinburgh.jpg

At a fundraiser in the town of Midrand, in the province Gauteng, near Johannesburg on Friday, singer Annie Lennox had strong words for the South African government’s AIDS policies.

“AIDS, as Madiba [Mandela] has said, is a human rights issue and should be treated as such in order to avoid this genocide that is affecting millions and millions of people around the world,” said Lennox in a speech. Lennox has previously been critical of the South African government’s position on suggesting some AIDS medications were toxic. “It is unacceptable that treatment has not been made available to those who need it most,” said Lennox.

The rock band Queen, which lost its lead singer Freddie Mercury to AIDS, released a new song entitled, Say It’s Not True, to coincide with World Aids Day. It has been made available as a free download from the band’s website. “By making the song available for free, we hope to help Nelson Mandela with his campaign to get across the message that no-one is safe from infection,” said Queen drummer Roger Taylor. “We have to be aware, we have to protect ourselves and those we love.”

In China, people distributed AIDS prevention brochures in the streets and promoted safe sex in cities like Beijing and Shanghai. In Changsha, official warning signs were put on hotel bedstands. The government announced on Friday an allocation of CNY860 million for AIDS prevention and control. According to official reports, there are estimated to be 700,000 people living with HIV/AIDS in China.

Also in China, the Miss World 2007 was in Sanya on World AIDS Day. The pageant presented a special tribute to the fight against AIDS, with a televised speech from former South African President Nelson Mandela, along with traditional dancers from South Africa who joined the contestants in a special song.

Friday, United States President George W. Bush urged the United States Congress to double the 2003 Emergency Plan for AIDS Relief to US$30 billion over the next five years. “Above all, we rededicate ourselves to a great purpose: We will turn the tide against HIV/AIDS—once and for all,” he said.

“I’m pleased to announce that Laura and I will travel to sub-Sahara Africa early next year,” Bush said. Sub-Saharan Africa suffered nearly three-quarters of AIDS-related deaths during 2006 and is home to two-thirds of those living with HIV/AIDS.

Wednesday, March 29, 2006The Australian House of Representatives today acknowledged the impact of the recent devastating Cyclone Larry and the efforts of the support given to the residents and communities of north Queensland in order to restore normal life.

Phillip Ruddock (Liberal, Berowra) moved a motion expressing this after Question Time today, which included a description of the devastation wrought on the area, the response by the Australian Government and the Australian Defence Force, and thanked the efforts of people for their “willingness to roll up their sleeves and get on with the job of cleaning up and rebuilding their towns and centres.”

The Leader of the Opposition, Kim Beazley (Labor, Brand) supported the motion, and congratulated the move to put General Peter Cosgrove in charge of operations, stating that soldiers “know how to work through logistics issues…how to work around officialdom or blockages”, praised both local federal and state members of Parliament, and especially the Labor Queensland state premier, Peter Beattie.

Bob Katter (Independent, Kennedy) was more critical in his speech. Katter thanked Beattie for his immediate response, but also described his confrontation with him and said how first responses were “simply not working”, but also praised Beattie’s decision on Cosgrove. Katter also described how the incident was “the worst natural disaster inAustralian history” and how the banana industry in north Queensland was decimated. Katter went on to describe the financial problems of the people in the region, the “huge gap” between the cost of rebuilding and insurance payouts, also asking “Are we going to pay people virtually nothing to sit on their backsides to do nothing or are we going to pay them a decent wage and have them rebuilding our communities for us?”

The debate is set to continue in the Main Committee, as an opportunity for many more members of the House of Representatives to speak to the motion, without taking up further time in the Chamber.

Vinay Deolalikar, a mathematician who works for HP Labs, claims to have proven that P is not equal to NP. The problem is the greatest unsolved problem in theoretical computer science and is one of seven problems in which the Clay Mathematics Institute has offered million dollar prizes to the solutions.

The question of whether P equals NP essentially asks whether there exist problems which take a long time to solve but whose solutions can be checked quickly. More formally, a problem is said to be in P if there is a program for a Turing machine, an ideal theoretical computer with unbounded amounts of memory, such that running instances of the problem through the program will always answer the question in polynomial time — time always bounded by some fixed polynomial power of the length of the input. A problem is said to be in NP, if the problem can be solved in polynomial time when instead of being run on a Turing machine, it is run on a non-deterministic Turing machine, which is like a Turing machine but is able to make copies of itself to try different approaches to the problem simultaneously.

Mathematicians have long believed that P does not equal NP, and the question has many practical implications. Much of modern cryptography, such as the RSA algorithm and the Diffie-Hellman algorithm, rests on certain problems, such as factoring integers, being in NP and not in P. If it turned out that P=NP, these methods would not work but many now difficult problems would likely be easy to solve. If P does not equal NP then many natural, practical problems such as the traveling salesman problem are intrinsically difficult.

In 2000, the Clay Foundation listed the “Clay Millenium Problems,” seven mathematical problems each of which they would offer a million dollars for a correct solution. One of these problems was whether P equaled NP. Another of theseseven, the Poincaré conjecture, was solved in 2002 by Grigori Perelman who first made headlines for solving the problem and then made them again months later for refusing to take the prize money.

On August 7, mathematician Greg Baker noted on his blog that he had seen a draft of a claimed proof by Deolalikar although among experts a draft had apparently been circulating for a few days. Deolalikar’s proof works by connecting certain ideas in computer science and finite model theory to ideas in statistical mechanics. The proof works by showing that if certain problems known to be in NP were also in P then those problems would have impossible statistical properties. Computer scientists and mathematicians have expressed a variety of opinions about Deolalikar’s proof, ranging from guarded optimism to near certainty that the proof is incorrect. Scott Aaronson of the Massachusetts Institute of Technology has expressed his pessimism by stating that he will give $200,000 of his own money to Deolalikar if the proof turns out to be valid. Others have raised specific technical issues with the proof but noted that the proof attempt presented interesting new techniques that might be relevant to computer science whether or not the proof turns out to be correct. Richard Lipton, a professor of computer science at Georgia Tech, has said that “the author certainly shows awareness of the relevant obstacles and command of literature supporting his arguments.” Lipton has listed four central objections to the proof, none of which are necessarily fatal but may require more work to address. On August 11, 2010, Lipton reported that consensus of the reviewers was best summarized by mathematician Terence Tao, who expressed the view that Deolalikar’s paper probably did not give a proof that P!=NP even after major changes, unless substantial new ideas are added.
