A scientific expedition to a remote glacier field in Canada's High Arctic may help researchers unlock the secrets about the beginning of life and provide insights for future exploration of our solar system.
A team assembled by the University of Calgary's Arctic Institute of North America plans to spend two weeks studying a sulfur-spewing spring on the surface of an ice field not far from the North Pole this summer, after it was discovered by Institute Executive Director Dr. Benoit Beauchamp during his travels in the area. Beauchamp, U of C adjunct professor Dr. Steve Grasby from the Geological Survey of Canada, and two graduate students will conduct the first extensive study of the spring after initial tests showed the geological oddity is home to a unique form of bacteria that has adapted to thrive in a cold and sulfur-rich environment.
"We really want to try and understand the plumbing system for this spring and where all this sulfur is coming from," Beauchamp said. "This is a very unusual feature on the earth's surface and it's an extreme ecosystem that could be a good model for how life first begins in a harsh environment."
The spring has also attracted the attention of the Canadian Space Agency and NASA, which are helping to fund the expedition, because it likely provides the best example on Earth for the conditions believed to exist on the surface of Jupiter's moon Europa. Ice-covered Europa is considered one of the best candidates for finding evidence of life on other planets within our solar system. Sending a probe to the planet is high on NASA's list of possible projects. Graduate student Damhnait Gleeson from the University Colorado, on a project sponsored by NASA's Jet Propulsion Laboratory, will be taking part in the study to determine if it will be worthwhile testing spacecraft and remote-control rover equipment on the glacier in the future.
"These are exciting times for planetary exploration in Canada, said Dr. Alain Berinstain, Director of Planetary Exploration and Space Astronomy at the Canadian Space Agency (CSA). "With the development of the Canadian Analogue Research Network (CARN) by the CSA, there are more opportunities than ever for Canadian researchers to further our understanding of other planets by studying analogues sites on Earth," Berinstain said. "These sulfur springs in the Arctic may just put us one step closer to answering that age old question: are we alone in the Universe?"
Beauchamp discovered the spring in the mid-1990s when he noticed a yellow stain on the snow while passing over the Borup Fiord Pass in a helicopter. He eventually visited the site and noticed the strong smell of rotten eggs that indicated the presence of sulfur. Grasby then visited the in 1999 and 2001 and collected samples of the water and mineral deposits from the spring, which contained new forms of bacteria and an extremely rare mineral known as vaterite.
Sulfur-loving organisms have been found living in extremely hot water around geothermal vents deep in the ocean floor but are seldom observed living in cold environments.
Beauchamp, Grasby, Gleeson and U of C graduate student Marie-Eve Caron leave for the glacier on June 21. From Ottawa, they will fly to Resolute, where they will be flown to the Eureka research station via Twin Otter airplane. The team will then reach the glacier by helicopter and set up a small camp near the base of the glacier where they will study the spring and acquire numerous water, mineral and rock samples.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
