For hundreds of nights during the next five years, the world’s most powerful digital camera will turn skyward, helping a team of physicists and astronomers from around the globe answer fundamental questions about our universe.
Physics undergraduate Jeysthur Ang has been awarded an Outstanding Undergraduate Researcher Prize (OURP) for research he carried out at CQT. He is the fourth student supervised at CQT to receive the National University of Singapore prize.
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have identified a series of clues that particular arrangements of electrical charges known as "stripes" may play a role in superconductivity—the ability of some materials to carry electric current with no energy loss.
Researchers from the universities in Mainz, Frankfurt, Hamburg, and Ulm have proposed a new platform for quantum simulation. In a theoretical paper recently published in Physical Review Letters, they show that a combined system of ultracold trapped ions and fermionic atoms could be used to emulate solid state physics.
Scientists have pushed back the boundaries of atom-based transport, creating a current by charac-terising the many-body effects in the transport of the atoms along a periodic lattice. This work by Anton Ivanov and colleagues from the Institute for Theoretical Physics, at the University of Heidel-berg, Germany, adopted a new analytical approach before comparing it to approximate numerical simulations, and is reported in a paper recently published in EPJ B.
Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only an all-encompassing theory of quantum gravity which unifies these two fundamental pillars of physics could provide an insight into how the universe began.
An international team of researchers presents fresh evidence that confirms the existence of the superheavy chemical element 115. The experiment was conducted at the GSI Helmholtz Center for Heavy Ion Research, an accelerator laboratory located in Darmstadt.
For millions of years after the Big Bang, there were no stars, or even galaxies to contain stars. During these “Cosmic Dark Ages,” neutral hydrogen gas dominated the universe. When clouds of primordial hydrogen gas started to collapse from gravity, they became stars.

Nobel Laureate Andre Geim of the University of Manchester, UK, has been named the 2012 recipient of the Richard E. Prange Prize and Lectureship in Condensed Matter Theory and Related Areas. Dr. Geim will receive a $10,000 honorarium and deliver a public presentation entitled "Random Walk to Graphene” at the University of Maryland, College Park, on Oct. 16, 2012.
The origin of cosmic rays in the universe has confounded scientists for decades. But a study by researchers using data from the IceCube Neutrino Observatory at the South Pole reveals new information that may help unravel the longstanding mystery of exactly how and where these “rays” (they are actually high-energy particles) are produced.
NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is giving the wider astronomical community a first look at its unique X-ray images of the cosmos. The first batch of data from the black-hole hunting telescope is publicly available today, Aug. 29, via NASA's High Energy Astrophysics Science Archive Research Center, or HEASARC.
The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer.
Using NASA’s super-sensitive Chandra X-ray space telescope, a team of astronomers led by Q. Daniel Wang at the University of Massachusetts Amherst has solved a long-standing mystery about why most super massive black holes (SMBH) at the centers of galaxies have such a low accretion rate—that is, they swallow very little of the cosmic gases available and instead act as if they are on a severe diet.
Disrupting the symmetrical structure of a solid-state topological crystalline insulator creates mass in previously mass-less electrons and imparts an unexpected level of control in this nascent class of materials, an international team of researchers reports in the current edition of Science Express.
Stanford solar scientists have solved one of the few remaining fundamental mysteries of how the sun works.
