In all the centuries that humans have studied chemical reactions, just 36 basic types of reactions have been found. Now, thanks to the work of researchers at MIT and the University of Minnesota, a 37th type of reaction can be added to the list.

A team of University of California, Riverside physicists recently received recognition for their work on the Compact Muon Solenoid (CMS) pixel detector, a particle tracker integral to the study of fundamental particle physics. Martina Malberti, Kira Burt, Manuel Olmedo and Mauro Dinardo make up part of the group responsible for repairing malfunctioning channels in the forward pixel detector.
Nuclear magnetic resonance -- that phenomenon where nuclei of certain atoms, when in a magnetic field, take in and give off measurable amounts of electromagnetic radiation -- is everywhere.
For three weeks in August, leading physicists from all over the world attended the Mass 2013 conference at CP³-Origins in Odense, Denmark. Lots of new calculations were presented, among them the results of the project ‘Dark Matter from a Composite Goldstone Boson’ – a lattice study of SU(2) gauge theory with two fundamental fermions.
A joint Australian-German research team led by Curtin University’s Dr Christian Hirt has created the highest-resolution maps of Earth’s gravity field to date – showing gravitational variations up to 40 per cent larger than previously assumed.
No one knows for sure, but it is not unlikely that the universe is constructed in a completely different way than the usual theories and models of today predict. The most widely used model today cannot explain everything in the universe, and therefore there is a need to explore the parts of nature which the model cannot explain. This research field is called new physics, and it turns our understanding of the universe upside down. New research now makes the search for new physics easier.
University of Calgary scientists have overcome an “Achilles’ heel” of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Astronomers have used the NASA/ESA Hubble Space Telescope and ESO's New Technology Telescope to explore more than 100 planetary nebulae in the central bulge of our galaxy. They have found that butterfly-shaped members of this cosmic family tend to be mysteriously aligned — a surprising result given their different histories and varied properties.
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.
