Iran Launches Monkey Into Space: Reports
Iranian space officials announced Monday (Jan. 28) that they have successfully launched a live monkey into orbit, inching closer to the Islamic republic's goal of a manned mission, according to news reports.
The space capsule, called Pishgam, which means "pioneer" in Farsi, reportedly returned the monkey alive after a suborbital flight to space and back, according to Iranian news agencies.
"The Islamic Republic of Iran has sent a monkey into space aboard an indigenous bio-capsule as a prelude to sending humans into space," the the Islamic Republic News Agency reported.
Space officials in the country have previously said that they hope to send a human into space by 2020 and put an astronaut on the moon by 2025.
Iran's defense minister, Ahmad Vahidi, told state TV that the success "paves the way for other moves," according to Agence-France Presse.
"The monkey which was sent in this launch landed safely and alive and this is a big step for our experts and scientists," Vahidi said.
Iran failed in a 2011 effort to launch a live monkey into space. News reports out of the country at the time did not explain what went wrong, but the plan had been to send a rhesus monkey into orbit atop a Kavoshgar-5 rocket.
Iran has made progress in spaceflight technology in recent years. The country sent its first domestically built satellite into space in February 2009 and launched a Kavoshagar-3 rocket in 2010 that delivered a rat, two turtles and a worm into space. Iran also sent Earth-observing satellites into orbit in 2011 and 2012.
Western critics have expressed concern over the potential military applications of Iran's rocket program, since boosters developed to reach space could also be used as long-range ballistic missiles. The Islamic republic has denied such ambitions for its space program.
In the early days of spaceflight for the United States and the Soviet Union, animals were used to test the safety and feasibility of launching a living being into space and bringing it back unharmed.
A rhesus monkey named Albert I was the first?monkey astronaut. He was launched aboard a U.S. military V-2 rocket from White Sands, New Mexico, in June 1948, but suffocated and died during the flight. A monkey named Yorick was the first monkey to live through a spaceflight. Yorick and 11 mice were recovered after an Aerobee missile flight of 236,000 feet from Holloman Air Force Base, New Mexico, in September 1951.

Study Bolsters Quantum Vibration Scent Theory
How does the sense of smell work? Today two competing camps of scientists are at war over this very question. And the more controversial theory has just received important new experimental confirmation.
At issue is whether our noses use delicate quantum mechanisms for sensing the vibrations of odor molecules (aka odorants). Does the nose, in other words, read off the chemical makeup of a mystery odorant?say, a waft of perfume or the aroma of wilted lettuce?by ?ringing? it like a bell? Chemistry and forensics labs do this all the time with spectrometers?machines that bounce infrared light off mystery materials to reveal the telltale vibrations that the light provokes. Olfaction might, according to the vibration theory of smell, do the same using tiny currents of electrons instead of infrared photons (see previous coverage of the vibration theory here).
The predominant theory of smell today says: No way. The millions of different odorants in the world are a little more like puzzle pieces, it suggests. And our noses contain scores of different kinds of receptors that each prefer to bind with specific types of pieces. So a receptor that is set to bind to a molecule called limonene sends a signal to our brains when it finds that compound, and that's one of the cues behind the smell of citrus. Likewise that same receptor wouldn't bind to hydrogen sulfide?which smells of rotten eggs.
So, the promoters of the standard theory say, the familiar chemical interactions between receptor and odorant are all that's needed to explain olfaction. No fancy quantum vibration theory is necessary.
Yet here's a twist: odorant molecules typically contain many hydrogen atoms. And hydrogen comes in multiple forms, each very chemically similar to the others. But those different isotopes of hydrogen do strongly affect how a molecule vibrates. So deuterium, containing a hydrogen nucleus that has both a proton and a neutron (as opposed to plain-old-hydrogen that has just a proton), might help scientists discriminate between the proposed vibration and standard chemical binding theories of olfaction.
According to new research published today in PLoS ONE, human noses can sniff out the presence of at least some kinds of deuterium. Specifically, experimenters found regular musk molecules smelled different from ones that contain deuterium. "Deuterated" musks, says researcher Luca Turin of the Alexander Fleming Biomedical Sciences Research Center in Greece, lose much of their musky odor and instead contain overtones of burnt candle wax.
The finding represents a victory for the vibration theory, Turin says. And, he adds, it makes some sense, when you consider the purpose of our olfactory ability?whatever its mechanism is. The natural world contains millions of types of molecules. Some are good for us, and some are bad. The nose helps to distinguish one from the other. "Olfaction is trying to be like an analytical chemist," Turin says. "It's trying to identify unknowns." Chemists identify unknowns using spectrometers. Olfactory receptors, according to the vibration theory, act like little wetware spectrometers.
Adding to Turin's quiver is a 2011 finding in Proceedings of the National Academy of Sciences indicating that drosophila flies, too, can smell the difference between a molecule called acetophenone (which to humans smells sweet) and its deuterated cousin.
That?s all well and good, says Eric Block, professor of chemistry at the University at Albany in New York State. But, he says, it hardly proves the vibration theory, which faces some contrary evidence. For one, he points out that Turin once claimed humans, like drosophilia, could sniff out a deuterated version of the molecule acetophenone from the regular stuff, yet in 2004 Nature Neuroscience published a contrary claim, that human noses can't smell the presence of deuterium in acetophenone (Scientific American is part of Nature Publishing Group). And, Turin himself says in his new paper that he has confirmed the negative 2004 finding, although he thinks he has an explanation for the failure: deuterated acetophenone has relatively few deuteriums in it and thus may generate a weak vibrational signal that is too weak for humans to detect. Block says Turin can't have it both ways: either noses can smell deuterium or they can't.

Alberta brings in policy to allow Sikhs to wear kirpan religious knives in court
EDMONTON - Alberta has come up with a policy to allow Sikhs to wear a ceremonial religious dagger called a kirpan in courthouses.
Under the Justice Department policy, a person must tell security officers they have a kirpan and wear it in a sheath, under clothing.
The blade of the kirpan can be no longer than 10 centimetres.
The World Sikh Organization says Alberta is the first province to bring in such a policy, which is partly based on rules developed for courts in Toronto.
The organization says Ontario is now working on a provincewide policy.
The Alberta rules stem from a human rights complaint filed in 2008 where a man wasn't allowed inside a Calgary court because he was wearing a kirpan.

Several catalysts making U.S. stocks attractive | Trading Desk ...
The U.S. Federal Reserve?s accommodative monetary policy is one reason to consider increasing exposure to U.S. equities, but it?s not the only catalyst making the trade attractive, says Charles Marleau, portfolio manager at Palos Management Inc. in Montreal.
?While we recognize that recent stock market performance has a lot to do with the application of easy money in terms of cost and availability, it remains that the US economy is doing fairly well when compared to other developed economies,? Mr. Marleau said in his latest weekly commentary.
?Corporate profits are beating expectations, confidence about the future has improved and the housing sector is on a significant uptick.?
Mr. Marleau said there is also a positive trend in U.S. companies repatriating their manufacturing, noting a recent survey by Boston Consulting Group that showed 44% of U.S.-based manufacturing companies are planning or considering bringing back production to the U.S.
He said the U.S. is gaining comparative advantage due to low interest rates and the backing of the Fed, both of which lead to business confidence.
North American energy input costs are lower than anywhere else in the world, he added, while five years of corporate and personal deleveraging which has led to a very strong financial foundation.
?Moreover, given that it appears that the Fed will likely make changes to monetary policy before Canada, more exposure to U.S.-denominated securities may prove to be a good move in that U.S. dollar could make gains against the Canadian dollar,? he wrote.
