MacLean, on his second spaceflight, joins five other astronauts on the first construction mission to the International Space Station since the Columbia disaster of 2003. The Nepean, ON native will play a crucial role in increasing the station's power. Using the robotic Canadarm, he will manoeuvre a set of solar panels from the shuttle to the station. He will then perform a spacewalk on Sept. 13 to release locks on the panels, allowing them to track the sun. (Elizabeth Howell reporting)
Faintest Stars Detected by Canadian Led Team
Posted: August 18, 2006
Astronomer Harvey Richer (external - login to view)
at the University of British Columbia used the Hubble telescope to study white dwarfs in star cluster NGC 6397, which is 8500 light years away. The light detected is the equivalent of a birthday candle on the moon. Astronomers have used white dwarfs in globular clusters as a measure of the universe's age. The universe must be at least as old as the oldest stars. White dwarfs cool down at a predictable rate. The older the dwarf, the cooler it is, making it a perfect "clock" that has been ticking for almost as long as the universe has existed. Richer and his team are using the same age-dating technique to calculate the cluster's age. NGC 6397 is estimated to be nearly 12 billion years old.

Researchers do not know yet if the effect will be beneficial or a damaging to the human immune system.
Canadian Team Tops Space Elevator Contest

A team from the University of Saskatchewan managed to get their robot the highest up a tether "to space" as a first step in a NASA initiative to build a space elevator. The idea is to use a thin but unimaginably strong ribbon tethered to an orbiting satellite. People and cargo would travel up the ribbon to space. This is the first year of the contest, and though nobody won the $50,000 prize, the Canadian team's robot reached 12 meters, higher than any of the the other six competitors. More at New Scientist

This problem which would normally take 3 - 6 years of computing time should complete in one day on CISS. While software is a major component, Paul Lu, a CISS researcher says, "Much more time and arm-twisting has been spent to convince people to include their systems in CISS. We accept, and are trying to work with, human nature. Technologists ignore human factors at their own peril."

The telescope was extremely cheap to build, costing 300 times less than the Hubble telescope. It will be launched in April 2003 atop a Russian rocket. Matthews hopes the Canadian telescope will confirm or disprove the existence of other planets which so far can only be inferred from the wobble of some stars.

Canadians begin catalogue of human proteome
Posted: January 11, 2002
Now that scientists have worked out the human genome, the next task is to figure out the human proteome, the total set of proteins the genome encodes. Researchers at the University of Toronto are using supercomputers to do it. In this week's Nature, working with colleagues in Heidelberg, Germany, Canadian geneticists led by Mike Tyers and Michael Moran use a supercomputer to unravel the highly complex interaction of the thousands of proteins coded in the genome of yeast. Their key finding: each protein is involved in numerous interactions and therefore new designer drugs targeted to specific proteins could have serious side effects.

Parasite genome stripped to bare essentials
Posted: November 23, 2001
"This is an exciting time for parasitology," says Patrick J. Keeling of the University of British Columbia, in a News and Views article in this week's Nature magazine refering to the discovery by French researchers that the parasitic microsporidion Encephalitozoon cuniculi has a genome less than 0.1% the size of the human genome and is even smaller than the genomes of many bacteria. Its genes have little ‘junk’ DNA between them. This has nearly erased the genomic record of the organism's evolutionary history, making it difficult to determine how it originated. According to Keeling, other emerging genome sequences will "usher in an age of comparative parasite genomics." If E. cuniculi is an indication, he concludes, "many ‘rules’ are about to be broken."

Australian scientists studying Canadian garter snakes (Thamnophis sirtalis parietalis) suggest in this week's Nature magazine that slow and sleepy male garter snakes might mimic females to fool other males into warming them up. These 'she-males' produce female pheromones at the end of hibernation, causing them to become engulfed in large 'mating balls' of amorous males — sometimes containing more than 100 snakes.
