Tuesday, March 22, 2005Volunteers began a 60 day bed-rest marathon on March 19 to study simulated weightlessness effects on women astronauts. The study, Women International Space Simulation for Exploration(WISE), is conducted at the MEDES Space Clinic in Toulouse, France.

The 12 women, selected from 1600 applicants hailing from France,Great Britain, Germany, Finland, The Netherlands, Poland and the Czech Republic began the study after a 20 day screening for baseline comparison data as the study progressed.

The women will conduct all activities from eating, bathing, and reading while lying in hospital beds tilted headfirst at a six degree angle. This particular position, called head-down tilt bed rest was determined from previous studies to remove the vertical load of gravity on the body, inducing changes similar to what astronauts in a genuine weightless environment experience [1].

Long term exposure to weightlessness creates a number of physiological and psychological problems in astronauts such as:

• Reduced capacity for physical exertion
• Muscle atrophy
• Affects of confinement and isolation
• Impaired circulatory function

A total of 24 women will participate in the study. A second group of 12 will join in September.

Three groups of eight women each will be studied over the course of the two campaigns of bed rest. One group will serve as a control, receiving no specific treatments, the second will exercise, while the third will receive nutritional supplements.

The study is designed to fill in gaps of knowledge on the differences between men and women during extended weightlessness. It also aims to develop countermeasures for reducing the debilitating effects of long spaceflights.

Participating agencies in the study include the European Space Agency, NASA, the French Space Agency and the Canadian Space Agency.

Rescuers are searching for the victims of the Tans Peru airliner crash which occurred earlier this month. Emergency services rescued 5 survivors on Thursday morning.

TANS say that 41 people were killed and a further 57 injured in this, the fifth airliner crash worldwide this month. The Boeing 737-200 airliner crash-landed in heavy jungle near the city of Pucallpa, 840 kilometers (522 miles) northeast of Lima, the capital city.

Peruvian authorities have ordered an investigation and have shipped the aircraft’s two flight data recorders, or “black boxes” to the United States for data retrieval.

Jorge Belevan said “We’ve also found five more survivors and that takes the number (of survivors) to 57. Two people are still missing and there are 41 dead,” Local authorities also said that the death toll is likely to rise due to inaccessible location of the crash site. This is the second TANS Peru plane crash in three years, following the January 2003 crash of flight 222 in the Peruvian rainforest. In that plane crash there were no survivors.

Peruvian government lawyer Marco Ochoa said that rescuers are opening the skin of the aircraft to determine whether there are more bodies trapped inside.

Survivors said that the plane was caught in a fierce storm about 10 minutes before the crash. The plane then caught fire and landed in swampland.

A letter and motion to be debated by Italian Parliament this week calls for action to address speculative bubbles and potential future financial crashes in the global economy. The motion asks for a global summit similar to the 1944 Bretton Woods United Nations Monetary and Financial Conference, which gave us the IMF and World Bank.

The letter raises questions about the sustainability of current financial trends, based on the highly speculative nature of today’s markets. For example, according to the letter, “It is estimated that the entire financial bubble, counting all financial derivatives and all other forms of existing debt, is equal to about $400 trillion, compared to a worldwide GDP of slightly more than $40 trillion”.

Last years collapse of Italian dairy company Parmalat, with “14.3 billion euros that must still be accounted for”, is given as evidence for “a lack of effective tools and controls regarding financial operations”. Enron, which famously collapsed in November 2001 revealing faudulent accounting practices from previously respected accounting firm Arthur Andersen, is given as another example.

Oddly, the largest collapse on record, that of WorldCom, is not mentioned, though the set of examples is not purported to be exhaustive. A number of other crashes are mentioned: the LTCM fund, Argentine bonds, Cirio, and Finmatica.

The motion, linked to supporters of the Lyndon LaRouche movement, is signed by Parliamentarians Lettieri, Soro, Delbono, Tolotti, Widmann, Villani Miglietta, Rosato, Albertini, Morgando, Diana, Luigi Pepe, Damiani, Ostillio, De Brasi, Maccanico, Carbonella, Paola Mariani, Grandi, Pistone, Giovanni Bianchi, Giacco, Benvenuto, Piscitello, Camo, Realacci, Squeglia, Rocchi, Iannuzzi, Intini, Meduri, Santino Adamo Loddo, Boccia, Villari, Chianale, Siniscalchi, Sandi, Cusumano, Cennamo, Annunziata, Rotundo, Bonito, Buemi, Pennacchi, Fanfani, Tarantino, Rodeghiero, Angioni, Detomas, and Nesi.

Debate was scheduled for March 14-18.

On Saturday, the plastic ban in the Indian state of Maharashtra came into force. In an attempt to minimise pollution, the state government has introduced a ban on single-use plastics.

The leader of the Yuya Sena political party, Aaditya Thackeray, said on Twitter, “The ban on single use disposable plastic cups, plastic bags, plastic straws, plastic plates and cutlery, styrofoam cutlery and non woven bags”. He added, “these are global issues now and we have taken a step to combat it”.

Plastic pollution has led to the choking of drains, marine pollution and a risk of animals consuming plastics. This year, India’s motto for World Environment Day — June 5 — was “Beat Plastic Pollution”. People violating the plastic ban are to face a fine of 5,000 Indian Rupees (INR) for the first offence. For the second offence, the fine is INR 10,000 and the third time offence is INR 25,000 and a three-month prison term. Deputy municipal commissioner Nidhi Choudhary said, “To weed out corruption, we plan to give inspectors payment gadgets for electronic receipts of the fines”.

The Maharashtra government has given a 90-day period for manufacturers to dispose of existing polyethylene terephthalate (PET/PETE) plastic spoons and plates, while shopkeepers and citizens in general have six months to dispose of plastics. However, the ban does not prohibit plastic usage for wrapping medicines or milk cartons thicker than 50 microns.

The state government had announced the decision for the plastic ban on March 23. According to NDTV’s report, Maharashtra is the eighteenth Indian state to enforce a state-wide plastic ban. Aaditya Thackeray also said, “I congratulate the citizens for making this into a movement, even before the ban was enforceable, giving up single use disposable plastic.”

A tropical tree-dwelling lizard has succeeded in a problem-solving test by learning to associate the color of a cap with a food reward, contesting the stereotype that reptiles are extremely limited cognitively compared to birds and mammals. The cognitive abilities of reptiles have rarely been studied.

In a color discriminating task, the lizards learned to flip over the correctly colored cap to reveal a worm hidden underneath. The experiment was conducted at Duke University and the results, published in the Royal Society journal Biology Letters, suggest that the problem-solving abilities of reptiles may be greater than previously thought.

The Puerto Rican lizard, (an anole), used in the study, is a well-studied species, known to excel at foraging food by being acutely aware of movement. Several lizards of this species were collected from Puerto Rico for the experiment.

Researches first wanted to determine if the six lizards used in the study were able to figure out how to flip off the cap to obtain the food. The agile reptiles quickly learned to use one of two ways to move the cap: they closed their jaws on the edge of the cap and dragged it off the food, or ran into the cap with their heads, tipping it over and grabbing the food.

The lizards were then given a choice between two caps; one was blue and the other was yellow and blue; under only one was the food reward of a worm. They quickly learned to distinguish which cap had the reward.

“They learned to associate the color of the [cap] with a food reward,” said Manual Leal, the Duke University researcher who led the study. Their success on a test that is based on worms and usually used on birds was “completely unexpected,” he said.

The lizards solved the problem in fewer tries than birds needed to flip the correct cap and pass the test, Leal explained. Lizards get just one chance per day because they eat less, while birds usually get up to six chances a day. Thus a mistake by a lizard means it must remember until the next day how to correct the mistake, Leal said.

And when the color of the caps was switched, after a few mistakes two of the lizards were able to figure out the trick. “We named these two Plato and Socrates,” said Leal.

Jonathan Losos, a biologist at Harvard University not involved in the study, said Leal’s experiment demonstrates that when faced with a new situation, most of the lizards were able to solve the problem. They had the ability to figure out the trick and disregard their previous learning; a sign of a cognitively advanced animal that some mammalian species cannot easily do.

The results “should cause researchers to re-evaluate what they think they know about the evolution of animal cognition,” Losos said.

Russian and Chinese armed forces began their first ever joint military exercises since the Korean War, when Russia was still part of the Soviet Union, on Thursday. The exercises are expected to last for eight days.

10,000 troops — about 1800 Russians, the rest Chinese — are participating in the war games. The exercises simulate United Nations-mandated police action to restore order in a fictitious country torn by ethnic unrest. They began in the eastern Russian port-city of Vladivostok and are supposed to culminate in a mock invasion involving beach landings and paratrooper drops off the coast of the Jiaodong peninsula in eastern China.

Russian and Chinese officials have framed the exercises as promoting international cooperation, but some in the US and elsewhere see the exercises as preparation for a possible future invasion of Taiwan, and as a challenge to US dominance in Asia — particularly in Afghanistan. The exercises come amid increasing speculation in the US that China may come to replace the US as the world’s greatest superpower.

Russia and China are working together to help form of a world order that will be based on multipolarity, respect for international law, and a leading role for the UN, Deputy Foreign Minister Alexander Alexeyev said on Monday, August 15, 2005.[1]

“The exercise will be carried out in the framework of the fight against international terrorism and extremism, to respond to new threats and challenges,” said Liang Guanglie, chief of staff of China’s armed forces.[2]

But others citing the use in the operation of advanced aircraft atypical of a peacekeeping operation, say the countries have ulterior motives. “The main target is the US. Both sides want to improve their position for bargaining in terms of security, politics and economics,” said Jin Canrong, professor of international relations at the People’s University of China.[3]

A Taiwanese official quoted by Mosnews.com said, China’s involvement in the operations represents “the biggest security threat in the Asiatic-Pacific region.” [4]

However other analysts speculate that Russia’s motivations for using the aircraft, including Tu-95 strategic bombers and Tu-22M long-range bombers, in the exercises may be to promote their sale to the Chinese.

“Military cooperation is linked with political and economic cooperation as part of a bigger package,” said Robert Karniol, Asia-Pacific editor for Jane’s Defence Weekly. “It’s not an adversarial posture.”[5]

Many have noted that the joint exercises are an emblem of increasingly warm relations between China and Russia since the dissolution of the Soviet Union. But writing In an editorial for the International Herald Tribune, Phillip Bowring disagrees, saying that the primary purpose of the operations is as a warning to the US. “The current Russia-China joint military exercises are not so much a symbol of trust and friendship between the two as a symptom of American overstretch. The two are reminding the United States of the limits of its unilateral global power.”[6]

Despite speculation into the motives of Russia and China, the US has given at least token support to the idea that the exercises could promote international interests. “We are following the exercises,” U.S. State Department spokesman Sean McCormack said this week. “We expect that they will be conducted in a manner that supports some mutual goal of regional stability shared by the United States, China and Russia.”[7]

Others say the operations are mainly a response to separatism and Islamic extremism in Russian Chechnya and the Chinese Xinjiang.

“The exercises are the logical continuation of the first signs of cooperation between Russia and China in the struggle against ‘orange revolutions,’ separatism and the dominant influence of the U.S. in the Euroasiatic sphere,” the Gazeta.ru news website wrote Thursday. Orange was the color adopted by supporters of last year’s revolution in Ukraine, which along with mass demonstrations in Georgia and Kyrgyzstan, brough pro-Western administrations to power. [8]

The war games have been called “Peace Mission 2005“.

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.
