Frost rejected the idea, but his UChicago successors thought differently. In 1986 they established the first in a series of telescopes at the South Pole to take advantage of its high elevation (9,301 feet), its clear, dry atmosphere, and its uninterrupted view of the same patch of sky. UChicago scientists have since become a scientific fixture of the South Pole, which now enters its second century of human activity.
UChicago deployed its first telescopes as part of the Cosmic Background Radiation Anisotropy Experiment (COBRA). The largest COBRA telescope, called Python, recorded measurements of the cosmic microwave background — the big bang’s afterglow — that were 10 to 100 times better than any other Earthbound site conducting such studies.
Then came Chicago’s South Pole Infrared Explorer (SPIREX), the only telescope in the world that had a continuous view of the crash of Comet Shoemaker-Levy 9 with Jupiter in July 1995.
The Degree Angular Scale Interferometer (DASI), which began operating in 2000, soon recorded slight temperature fluctuations in the cosmic microwave background. DASI’s precise measurements enabled cosmologists to verify the theory that ordinary matter, of which humans, stars and galaxies are made, accounts for less than 5 percent of the universe’s total mass and energy.
DASI also made the first detection of the much fainter polarization in the cosmic microwave background, which made the cover of the Dec. 19, 2002 issue of Nature.
Succeeding DASI was the South Pole Telescope, which collected its first data in February 2007. SPT studies the mysterious phenomenon of dark energy, which makes the expansion of the universe accelerate.
The South Pole Telescope will be featured as a Science Bulletin next summer in a high-definition, seven-minute documentary at the American Museum of Natural History in New York City.

Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents
22.05.2015 | Universität Basel
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
Development and implementation of an advanced automobile parking navigation platform for parking services
To fulfill the requirements of the industry, PolyU researchers developed the Advanced Automobile Parking Navigation Platform, which includes smart devices,...

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
