An international group of astrophysicists has found evidence strongly supporting a solution to a long-standing puzzle about the birth of some of the most massive stars in the universe.
In a recent publication B. Slomski and co-workers have been able to follow how spin-orbit interaction causes anti-prallel spin states to interact. The resulting spin flip yields an unexpected spin texture.
An exceptionally close stellar explosion discovered on Jan. 21 has become the focus of observatories around and above the globe, including several NASA spacecraft. The blast, designated SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type Ia supernova to occur during the life of currently operating space missions.
New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of Warsaw. The materials and elements used to form these structures allow us forecast new trends in solotronics – a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.
Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors.
Nanoscale Superconducting QUantum Interference Devices (nanoSQUIDs) are potentially the most sensitive measurement devices in the world. They detect changes in an electromagnetic property known as magnetic flux, which means they can be used to detect single photons or to characterise the tiny quantum oscillations in nano-electromechanical systems (NEMS).
Quantum Biosystems today announced the release of raw data access to its first reads. The company released reads showing an accuracy of more than 99% in non-homopolymer regions and homopolymer indels at a rate of ~10%. This release allows researchers to evaluate the platform and engage in its validation and development. It marks a major milestone in the single molecule electrical sequencing of DNA.
An international team, including researchers from CNRS and the Paris Observatory at LESIA (Observatoire de Paris/CNRS/Université Pierre et Marie Curie/Université Paris-Diderot) and at IMCEE (Observatoire de Paris/CNRS/Université Pierre et Marie Curie/Université Lille 1), has discovered intermittent emissions of water vapor on Ceres, the largest of the asteroids, using the Herschel space telescope. These findings are published in the journal Nature dated 23 January 2014.
Three NASA science instruments are being prepared for check-out operations aboard the European Space Agency's Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus in November.
Research at CERN receives 6.685 million Danish kroner from NUFI, the National Committee for Research Infrastructure under the Danish Agency for Science, Technology and Innovation. The funds are granted for the operation and the development of the Danish experimental work at CERN in 2014.
In its first 25 days of operations, the newly reactivated NEOWISE mission has detected 857 minor bodies in our solar system, including 22 near-Earth objects (NEOs) and four comets. Three of the NEOs are new discoveries; all three are hundreds of meters in diameter and dark as coal.
UBC scientists have developed a new type of optical spectroscopy, dubbed “centrifuge spectroscopy”, capable of probing molecules in an unprecedented regime of ultrafast “super” rotation. An optical centrifuge is a laser pulse with rotating linear polarization. Due to the light-induced dipole moment, molecules line up along the polarization vector and faithfully follow its rotation, spinning up to ultra-high angular frequencies, which cannot be reached by any other means.
If the chemical bonds that hold together the constituent atoms of a molecule could be tuned to become stronger or weaker, certain chemical properties of that molecule might be controlled to great advantage for applications in energy and catalysis. Berkeley Lab researchers at the Molecular Foundry, in collaboration with researchers from Rice University, were able to accomplish this feat by using an applied voltage and electric current to tune the strength of chemical bonds in fullerene or “buckyball” molecules.
How would electrons behave if confined to a wire so slender they could pass through it only in single-file?
Professor Jairo Sinova of Johannes Gutenberg University Mainz (JGU) has been allocated a highly coveted ERC Synergy Grant to carry out spintronics research together with project partners from the United Kingdom and the Czech Republic. The European Research Council (ERC) uses Synergy Grants to make it possible for outstanding scientists to work together on trailblazing projects.
