Forscher der University of Waterloo und der Universität Innsbruck haben erstmals drei miteinander verschränkte Photonen unabhängig von einander gemessen. Die in der Zeitschrift Nature Photonics veröffentlichten Ergebnisse bestätigen eindrucksvoll die Theorie der Quantenverschränkung.

Quantenphysik zeichnet sich durch einige für den Laien schwer verständliche Eigenschaften aus. So geht die klassische Physik davon aus, dass Vorgänge nur Auswirkungen auf ihre direkte räumliche Umgebung haben. Die in der Quantenmechanik formulierte Möglichkeit, dass verschränkte Teilchen auch über weite Distanzen hinweg stark miteinander verbunden sein können, veranlasste Albert Einstein einmal dazu, von einer „spukhaften Fernwirkung“ zu sprechen. Bis heute suchen deshalb Zweifler nach möglichen verborgenen Eigenschaften, die die Quantenmechanik doch den Gesetzen der klassischen Physik unterordnen. Diese Bemühungen erfahren nun erneut einen Rückschlag. Mit der örtlich unabhängigen Messung von drei miteinander verschränkten Photonen bestätigen Physiker um Gregor Weihs vom Institut für Experimentalphysik der Universität Innsbruck sowie Thomas Jenewein und Kevin Resch vom Institute for Quantum Computing (IQC) der University of Waterloo in Kanada eindrucksvoll die Richtigkeit der Quantenmechanik.

South African scientists to develop rugged microservers to handle the harsh desert conditions, explore new computer architectures and develop advanced algorithms for radio astronomy imaging

Pretoria, South Africa – 11 Mar 2013: Square Kilometer Array (SKA) South Africa, a business unit of the country’s National Research Foundation is joining ASTRON, the Netherlands Institute for Radio Astronomy, and IBM in a four-year collaboration to research extremely fast, but low-power exascale computer systems aimed at developing advanced technologies for handling the massive amount of data that will be produced by the SKA, which is one of the most ambitious science projects ever undertaken.

The SKA is an international effort to build the world’s largest and most sensitive radio telescope, which is to be located in Southern Africa and Australia to help better understand the history of the universe. The project constitutes the ultimate Big Data challenge, and scientists must produce major advances in computing to deal with it. The impact of those advances will be felt far beyond the SKA project—helping to usher in a new era of computing, which IBM calls the era of cognitive systems. (more…)

NASA’s Kepler Discovers 461 New Planet Candidates

PASADENA, Calif. – NASA’s Kepler mission Monday announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun’s “habitable zone,” the region in the planetary system where liquid water might exist on the surface of a planet.

Based on observations conducted from May 2009 to March 2011, the findings show a steady increase in the number of smaller-size planet candidates and the number of stars with more than one candidate. (more…)

Global Research Team Discovers New Alzheimer’s Risk Gene

Scientists have discovered a rare genetic mutation that increases the risk of Alzheimer’s disease.

The international team, led by researchers at the UCL Institute of Neurology, studied data from more than 25,000 people and found a link between a rare variant of the TREM2 gene – which is known to play a role in the immune system – and a higher risk of Alzheimer’s.

The paper, which is published in the New England Journal of Medicine, has major implications for our understanding of the causes of Alzheimer’s and the authors believe it is potentially the most influential gene discovery for the disease in the last two decades. (more…)

UD ranks third among U.S. public doctoral institutions in study abroad participation

The University of Delaware ranks third in study abroad participation among U.S. public doctoral institutions, according to the 2012 Open Doors report released Nov. 13 by the Institute of International Education (IIE).

During the 2010–11 academic year, more than one out of every three UD students (34.7 percent) studied abroad. Most pursued “short term” programs of eight weeks or less. (more…)

UD joins research team teaching robots to respond in disaster emergencies

How do you teach a robot to get into vehicle and drive it? Three University of Delaware professors plan to figure it out by the end of next year.

Christopher Rasmussen, Ioannis Poulakakis and Herbert Tanner are part of a team competing in a new U.S. Defense Advanced Research Projects Agency (DARPA) Challenge. The team, with members from 10 schools, led by Drexel University, is one of several groups worldwide working to advance robotics technology for disaster relief. (more…)

NASA Radar Penetrates Thick, Thin of Gulf Oil Spill

PASADENA, Calif. – Researchers at NASA’s Jet Propulsion Laboratory and the California Institute of Technology in Pasadena have developed a method to use a specialized NASA 3-D imaging radar to characterize the oil in oil spills, such as the 2010 BP Deepwater Horizon spill in the Gulf of Mexico. The research can be used to improve response operations during future marine oil spills.

Caltech graduate student Brent Minchew and JPL researchers Cathleen Jones and Ben Holt analyzed NASA radar imagery collected over the main slick of the BP Deepwater Horizon oil spill on June 22 and June 23, 2010. The data were acquired by the JPL-developed Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) during the first of its three deployments over the spill area between June 2010 and July 2012. The UAVSAR was carried in a pod mounted beneath a NASA C-20A piloted aircraft, a version of the Gulfstream III business jet, based at NASA’s Dryden Aircraft Operations Facility in Palmdale, Calif. The researchers demonstrated, for the first time, that a radar system like UAVSAR can be used to characterize the oil within a slick, distinguishing very thin films like oil sheen from more damaging thick oil emulsions.

Bounce, Skid, Wobble: How Huygens Landed on Titan

Piecing together the events of the farthest touchdown a manmade spacecraft has ever made on an alien world reveals new clues about Titan’s surface and helps plan future missions to moons and planets.

The Huygens probe, ferried to Saturn’s moon Titan by NASA’s Cassini spacecraft, bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Titan in January 2005, a new analysis reveals. The moon’s surface is more complex than previously thought.

Scientists reconstructed the chain of events by analyzing data from a variety of instruments that were active during the impact, in particular changes in the acceleration experienced by the probe. The probe was supplied by the European Space Agency and named after the Dutch 17th century astronomer Christiaan Huygens. (more…)
