The depths of space are much closer to home following the University of Albertas acquisition of a meteorite that is the only one of its kind known to exist on Earth! What makes it so rare? The meteorite is pristine – that is, still frozen and uncontaminated – and so provides an invaluable preserved record of material from when the solar system formed 4.57 billion years ago.
The Tagish Lake Meteorite is carbonaceous chondrite and, as such, represents primitive material from which the solar system formed. The meteorite is rich in pre-solar grains – grains from other stars that were present near our solar system when it formed. The meteorite contains primitive molecules that are the building blocks of the components necessary for life. The pristine state of the meteorite makes it especially important for scientific research purposes; it presents an unprecedented opportunity to look for extraterrestrial ices.
The University of Alberta, through the Department of Museums and Collections Services and the Department of Earth and Atmospheric Sciences, led a consortium of partners that, together, acquired the pristine samples for mutual research and heritage interests. These partners include the Department of Canadian Heritage, the Royal Ontario Museum, Natural Resources Canada, and the Canadian Space Agency.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
